It has been reported that more than 50% of ETTs arise in the uterine cervix or the lower uterine segment. Here, we report a case of ETT within the lower uterine segment and cervical canal and discuss its manifestations,possible causes, and related influencing factors.CASE SUMMARY A 35-year-old woman(gravida 7, miscarriage 3, induction 2 with 1 being twins,para 2 of cesarean section, live 2), who had amenorrhea for 9 mo after breastfeeding for 22 mo after the last cesarean section, was diagnosed with ETT. The lesion was present in the lower uterine segment and endocervical canal with severe involvement of the anterior wall of the lower uterine segment and the front wall of the lower uterine segment where the cesarean incisions were made.Laboratory tests showed slight elevation of serum beta-human chorionic gonadotropin. Intraoperative exploration showed the presence of a normal-sized uterus body with an enlarged tumor in the lower uterine segment. The surface of the lower uterine segment was light blue, the entire lesion was approximately about 8cm × 8 cm × 9 cm, with compression and displacement of the surrounding tissue.Histological examination diagnosed ETT. Immunohistochemical analysis showed positive expression of p63, with a Ki-67 proliferation index of 40%.CONCLUSION A search of the PubMed database using the search terms "cesarean section" and "epithelioid trophoblastic tumor" retrieved nine articles, including 13 cases of ETT and ETT-related lesions, all 13 cases had a history of cesarean section, and the lesions were all located at the cesarean section incision on the anterior wall of the lower uterine segment. The present case is the 14th reported case of ETT after cesarean section. Therefore, we deduced that cesarean section trauma had an important effect on the occurrence of ETT at this site.展开更多

[WT5”BX]Methods.[WT5”BZ]We retrospectively analyzed 68 cases of gestational trophoblastic neoplasia treated by hysterectomy from 1985～1997 at PUMC hospital. Thirty eight cases were diagnosed of choriocarcinoma and 30 were invasive mole. [WT5”BX]Results.[WT5”BZ]Twenty three elder patients who didn’t desire to preserve fertility were selected for hysterectomy after shorter courses of chemotherapy, 22 of them had a complete remission(95 6%), the total aver age courses of chemotherapy was 4 2. Of twenty seven chemorefractory cases who were suspected of a refractory isolated lesion in the uterus, delayed hysterectomy as an adjunct to chemotherapy was performed, 20 of them got a complete remission(74 1%), the total average courses of chemotherapy were 9 4. Emergency hysterectomy is indicated in 18 patients with uterine perforation or life threatening hemorrhage, 17 cases had a complete remission(94 4%), the total average courses of chemotherapy were 7 6. [WT5”BX]Conclusion.[WT5”BZ]Although the development of effective chemotherapy has resulted in improved survival of patients with gestational trophoblastic tumor, hysterectomy remains an important adjuncts in the treatment of a selected subset of patients; in order to operate more completely and prevent recurrence, it’s better to perform extended hysterectomy for the indicated patients.展开更多

There is a wide clinical spectrum of presentation and behaviour ranging from a benign condition to an aggressive disease with a fatal outcome. We report a case of placental site trophoblastic tumor in 23-year-old women with irregular vaginal bleeding during postpartum lactation period. In addition to persistent low level β-hCG titers, ultrasound examination revealed a suspicious low-echoic area in the myometrium consistent with gestational trophoblastic disease. After histopathological examination of the specimen achieved by ultrasound-guided dilatation and curettage of the uterus, the placental site trophoblastic tumor diagnosis was made and subsequently total abdominal hysterectomy was performed. The patient had an uneventful recovery, and no recurrence was detected for 40 months in the follow-up period.展开更多

GTN presents different degrees of proliferation, invasion and dissemination, but, if treated in reference centers, has high cure rates, even in multi-metastatic cases.The diagnosis of GTN following a hydatidiform molar pregnancy is made according to the International Federation of Gynecology and Obstetrics(FIGO)2000 criteria: four or more plateaued human chorionic gonadotropin(hCG)concentrations over three weeks; rise in hCG for three consecutive weekly measurements over at least a period of 2 weeks or more; and an elevated but falling hCG concentrations six or more months after molar evacuation. However,the latter reason for treatment is no longer used by many centers. In addition,GTN is diagnosed with a pathological diagnosis of CCA or PSTT/ETT. For staging after a molar pregnancy, FIGO recommends pelvic-transvaginal Doppler ultrasound and chest X-ray. In cases of pulmonary metastases with more than 1cm, the screening should be complemented with chest computed tomography and brain magnetic resonance image. Single agent chemotherapy, usually Methotrexate(MTX) or Actinomycin-D(Act-D), can cure about 70% of patients with FIGO/World Health Organization(WHO) prognosis risk score ≤ 6(low risk), reserving multiple agent chemotherapy, such as EMA/CO(Etoposide,MTX, Act-D, Cyclophosphamide and Oncovin) for cases with FIGO/WHO prognosis risk score ≥ 7(high risk) that is often metastatic. Best overall cure rates for low and high risk disease is close to 100% and > 95%, respectively. The management of PSTT/ETT differs and cure rates tend to be a bit lower. The early diagnosis of this disease and the appropriate treatment avoid maternal death,allow the healing and maintenance of the reproductive potential of these women.展开更多

The expression of c-erbB2 was detected immunohistochemically by monoclonal antibody against the gene on the formalin-fixed paraffin sections of 21 hydatidiform moles, 21 invasive moles, 20 choriocarcinomas and 30 normal placentas. Results showed that the expression level of c-erbB2 was significantly higher in gestational trophoblastic tumor than in hydatidiform mole and normal placenta of midterm and term pregnancy (P<0.05), while there was no significant difference between patients with gestational trophoblastic tumor of stage Ⅲ, Ⅳ and those of stage Ⅰ, Ⅱ. It was demonstrated that overexpression of c-erbB2 may closely associated with malignant transformation of hydatidiform mole, not only providing important insight into pathogenesis of gestational trophoblastic tumor, but also having an important significance for the early diagnosis and early treatment of gestational trophoblastic tumor.展开更多

Taking Leventhal’s Common Sense Model as a starting point, this study aims to investigate how illness perception could influence patients’ psychological adaptation to these rare diseases. Thirty-seven women completed: the Illness Perception Questionnaire-Revised, the Beck Depression Inventory Short Form, the State-Trait Anxiety Inventory, and the Fertility Problem Inventory. Results show that the perception of severe illness consequences significantly predicts the level of anxiety patients reported at the time of questionnaire completion. Furthermore, mental representations of illness present a significant association with infertility-related stress. Specifically, the belief in the efficacy of the treatment results in fewer feelings of discomfort and isolation from family and social context due to infertility-related problems. Since patients’ illness perception was found to have a specific impact on both anxiety and infertility-related stress, this variable should be considered in the planning of a clinical intervention.展开更多

Subjects and Methods: A retrospective analysis of 13 cases of GTT in China was performed. Clinical appearances, serum human chorionic gonadotropin (hCG) levels, sonographic findings, Doppler waveforms, and patient outcomes were followed up. Color Doppler ultrasound was performed to diagnose the presence of GTT, detect metastasia lesion in abdominopelvic cavity, assess disease recurrence, and monitor the efficacy of chemotherapy. Results: Of the 13 patients with GTT, 4 had choriocarcinoma which 3 cases occurred after an abortion, 1 after a year of dilation and suction evacuation for the hydatidform mole. Metastasia lesion in abdominopelvic cavity was detected by color Doppler ultrasound in all cases of choriocarcinoma, among which the metastasia lesion were found at uterine fundus, near uterus, colon and cystic vascular space near the uterus, repectively. 9 cases with an invasive hydatidiforn mole (IHM) occurred after one to three months of dilation and suction evacuation for the hydatidform mole, consistant with the hCG levels markedly elevating. Metastasia lesion in abdominopelvic cavity was also detected by color Doppler ultrasound besides invasive lesion in uterine muscular layer in all cases of IHM, among which 3 cases showed metastasia lesion in cystic vascular space near the uterus, 2 cases were detected in side wall of pelvic cavity, while the rest were found in abdominal cavity, right kidney, colon and near uterus, respectively. Meanwhile, the image of metastasia lesion with IHM was similar to choriocarcinoma’s. And the reticular structure, the cystic vascular space and solid lesion may be showed by ultrasound. The metastasia lesion had abundant flow. Doppler waveforms showed resistive indices of 0.34 (SD 0.07) for metastasia lesion. There was the same lower-impedance as invasive lesion in uterine muscular layer. Except an IHM with the renal metastasia lesion having been followed, abnormal sonographic and Doppler findings in other metastasia disease all disappeared after surgical operation or chemotherapy were successful. Conclusions: Sonography and Doppler imaging were helpful in detecting metastasia lesion in abdominopelvic cavity, and in following the effectiveness of chemotherapy. And it should be taken full examination for GTT by Color Doppler ultrasound in order to avoid mistake.展开更多

Renal metastasis is of infrequent occurrence. Among previous case reports of renal metastasis in GTN, this is the youngest woman presenting a large renal lesion concurrent with pulmonary and brain metastases. Disease remission had been achieved by treatment with combined chemotherapy and whole brain radiation, although acute myeloblastic leukemia (AML) developed later.展开更多

Although clinically ETT behave in variable fashion, it is considered as a potentially malignant tumor, fatal malignancy occurs in 10% of the cases. Case and Conclusion: A 41 years old patient, who previously underwent Tompkins operation because of congenital uterine septum was admitted to our clinic due to irregular bleeding. Despite of serum hCG levels under the upper limit of normal, histopathology analysis of D&C obtained endometrial samples confirmed the presence of ETT by immunostainings. Henceforth we performed prompt abdominal hysterectomy and preserved the normal structured ovaries. According to the müllerianosis theory of endometriosis aberrant differentiation or migration could cause spreading of cells throughout the fetal organogenesis of the uterus. These cells in an apoptosis week environment might correlate with the initiation of ETT. As a conclusion we suggest further studies to assess the link between ectopic cells and ETT, to gain a better understanding in the pathomechanism of the tumor.展开更多

Methods: The study was performed at Oncology Unit, Maternity Hospital, Ain Shams University in the period from November 2015 to December 2018. Forty cases of complete mole, after evacuation and follow up of serum human chorionic gonodotrophin (β-hCG) titre until it reached zero level (group I) and forty post molar GTN cases (group II) were included in the study. Doppler ultrasound of the subendometrial and intramural blood flow was done for all cases of group I and II. Doppler included two dimensional and three dimensional power Doppler indices. Group II received Methotrexate (MTX) and folinic acid in a dose of 8-day MTX-FA regimen. Doppler follow up for six months of group II concurrently with the chemotherapy regimen was done. Results: A statistically significant difference was found between group I and II regarding initial readings of all Doppler parameters. Follow up for 6 months of GTN cases revealed progressive statistically significant decrease of intramural and subendometrial three dimensional power Doppler (3DPD) indices, while there was a significant increase in two dimensional (2D) Doppler parameters. Four cases were resistant to Methotrexate chemotherapy. Cut off values were determined for prediction of GTN. Multivariate analysis revealed that the most predictive parameter was the subendometrial pulsatility index (PI), odds ratio = 10.63 (95% CI: 1.30 - 86.89). The cut-off point for sub-endometrial PI was: 2.05 (AUC, 90%;sensitivity, 88%;specificity, 76%, PPV 78%, and NPV 86%) with a diagnostic accuracy of 87%. To and Fro sign may be considered a pathognomonic intramural ultrasound sign for prediction of GTN chemo-resistance or choriocarcinoma. Conclusion: Cut off values for Doppler parameters can be used for early predication of GTN. Doppler ultrasound indices can be used during follow up of GTN cases concurrently with serum β-hCG to monitor the response to treatment.展开更多

However, many cases are resistant to first line chemotherapy. Objective: The aim of the study is to report our 5 years experience in the management of GTN cases with special stress on the chemo-resistant cases. Methods: The study was performed through reviewing the records of 51 patients who were diagnosed as GTN during the period from 1/1/2006 to 31/12/2010 in Mansoura University Hospital, Egypt. Results: Resistance to methotrexate therapy was reported in 15.15% of low risk cases and received etoposide or cisplatinum/etoposide. Sixty percent of high risk cases were resistant to MAC combination and received salvage chemotherapy or hysterectomy. There was significant correlation between patient response and initial B-hCG, as well as WHO risk score (P value = 0.001 in both) but correlations with age, parity, type of antecedent pregnancy, and histopathology were non significant (p = 0.95, 0.53, 0.47& 0.83 respectively). Conclusion: Low risk GTN cases who were resistant to methotrexate monotherapy received etoposide or cisplatinum/etoposide as a second-line therapy. High risk GTN cases who were resistant to MAC combination received second-line combination chemotherapy and/or hysterectomy. WHO risk score and initial B-hCG were correlated to resistance to first line chemotherapy.展开更多

Methods: This study was performed at Gynaecologic and Obstetric Clinic of Dakar Teaching Hospital, the reference Centre of Gestational Trophoblastic Disease in Senegal. At the beginning of 2011, patients were followed according to FIGO’s recommendations. From 2011 to 2014, we diagnosed 88 low-risk gestational trophoblastic neoplasia (GTN) patients (WHO score < 7). Low-risk patients started their treatment with methotrexate (MTX) based on the 8-day protocol consisting of 1 mg/kg MTX in combination with 0.1 mg/kg folinic acid (FA) every other day. Resistance to treatment was the main outcome. We studied the association of different prognostic factors included in the World Health Organisation (WHO) scoring system and resistance to the initial single agent chemotherapy. Results: Eighty-eight patients were diagnosed for GTN during the study period. Average age was 31 years. The antecedent pregnancy was molar in 98.1% of cases. Seventy-four patients underwent remission after single agent-chemotherapy. Resistance rate to single-agent chemotherapy was 15.9% (14 patients). Nine of them achieved remission after second line chemotherapy. WHO score was significantly associated with the risk of resistance to single-agent chemotherapy. Other variables included in the WHO as age, antecedent pregnancy, pre-treatment hCG, tumour size and FIGO stage were not significantly associated with resistance. We report five fatal cases. Conclusion: The 8-day protocol consisting of 1 mg/kg MTX in combination with 0.1 mg/kg folinic acid (FA) every other day is effective for women with LRGTN. The only significant prognostic factor for failure is pretreatment WHO score. We highly recommend the use of this protocol particularly in developing countries where methotrexate is available, affordable and relatively safe.展开更多

Methods: Avidin-biotin immunoperoxidase techniques with polyclonal antibodies against EGF, EGFR were used to examine 53 cases of GTD, including complete hydatidiform mole(16),invasive mole(20),gestational choriocarcinoma(17).Results:EGF was mainly localized on syncytiotrophoblasts (ST), and was found less on cytotrophoblasts. Cytologic localization of EGFR showed the similar results. The positive rate of EGF and EGFR were 0.625, 0.813 in hydatidiform mole, 0.405, 0.450 in invasive mole and 0.118, 0.235 in gestational choriocarcinoma. There was significant difference of EGF or EGFR among hydatidiform mole group and other groups, respectively (P<0.05). Conclusion:The cellular levels of EGF and EGFR decreased gradually in the development of GTD. It implied that the autocrine and paracrine mechanism may play an important role on the proliferation and differentiation of trophoblast cells and the disorder of the system may lead to GTD malignant transformation.展开更多

Methods: A total of 45 cases of trophoblastic tumor with pulmonary metastases treated by lung lobectomy from 1985~2002 at PUMC hospital were retrospectively analyzed. Seven cases were diagnosed as invasive mole and thirty-eight as choriocarcinoma. Results: Lung lobectomy was performed in all of these patients after several courses of chemotherapy. Seven cases of invasive mole reached complete remission. Eleven cases of choriocarcinoma with stage Ⅲa had received average 13 courses of chemotherapy, 10 of them reached complete remission. Seventeen cases of choriocarcinoma with stage Ⅲb had received average 14.3 courses of chemotherapy, 11 of them reached complete remission. Ten cases of choriocarcinoma with stage Ⅳ had received average 15 courses of chemotherapy, six of them reached complete remission. In the 45 patients, histologic examination disclosed haemorrhagic necrotic tissue in 27 patients, 17 of them reached complete remission(63%). Histologic examination also revealed fibrosis around the focus in 16 patients, 14 of them reached complete remission(88%). Tuberculosis was found in 2 patients.Conclusions: Although the development of effective chemotherapy has resulted in improved survival of patients with gestational trophoblastic tumor, lung lobectomy remains an important adjunct treatment in a selected subset of patients. Pathological examinations can help to estimate the prognosis.展开更多

The frequent absence of clear protocols and guidelines for the correct diagnosis of the pathology results in inadequate classification, imprecise treatment and failed post-therapeutic observation, increasing the risk of relapses, morbidity and mortality. The present study aims to point out updated national and international practice protocols of diagnosis of GTD, through an integrative review. Seven articles were selected and it was observed that the main international reference centers are agreed with the management suggested by the IFGO (International Federation of Gynecology and Obstetrics), being the conduct in the Hydatidiform Mole (HM): evacuation by suction and curettage under ultrasound guidance, followed by hCG monitoring every 1 - 2 weeks until normalized (usually one month for Partial Hydatidiform Mole six months for Complete Hydatidiform Mole and one year for Gestational Trophoblastic Neoplasia). Unfortunately, regarding the diagnosis of MH, the guidelines of some countries show the absence or difficulty of access to the karyotype test and ploid p57 or pelvic ultrasound accompanying the uterine curettage, contrary to what is proposed by the IFGO guideline. Establishing and complying with consistent guidelines can improve patient care, with early diagnosis of the pathology and its complications, reducing the rate of recurrence, morbidity and mortality, especially in less developed countries.展开更多
文摘BACKGROUND Epithelioid trophoblastic tumor(ETT) is the rarest type of gestational trophoblastic tumor(GTT). It has been reported that more than 50% of ETTs arise in the uterine cervix or the lower uterine segment. Here, we report a case of ETT within the lower uterine segment and cervical canal and discuss its manifestations,possible causes, and related influencing factors.CASE SUMMARY A 35-year-old woman(gravida 7, miscarriage 3, induction 2 with 1 being twins,para 2 of cesarean section, live 2), who had amenorrhea for 9 mo after breastfeeding for 22 mo after the last cesarean section, was diagnosed with ETT. The lesion was present in the lower uterine segment and endocervical canal with severe involvement of the anterior wall of the lower uterine segment and the front wall of the lower uterine segment where the cesarean incisions were made.Laboratory tests showed slight elevation of serum beta-human chorionic gonadotropin. Intraoperative exploration showed the presence of a normal-sized uterus body with an enlarged tumor in the lower uterine segment. The surface of the lower uterine segment was light blue, the entire lesion was approximately about 8cm × 8 cm × 9 cm, with compression and displacement of the surrounding tissue.Histological examination diagnosed ETT. Immunohistochemical analysis showed positive expression of p63, with a Ki-67 proliferation index of 40%.CONCLUSION A search of the PubMed database using the search terms "cesarean section" and "epithelioid trophoblastic tumor" retrieved nine articles, including 13 cases of ETT and ETT-related lesions, all 13 cases had a history of cesarean section, and the lesions were all located at the cesarean section incision on the anterior wall of the lower uterine segment. The present case is the 14th reported case of ETT after cesarean section. Therefore, we deduced that cesarean section trauma had an important effect on the occurrence of ETT at this site.

文摘Placental site trophoblastic tumor is a rare sub-group of gestational trophoblastic neoplasia. There is a wide clinical spectrum of presentation and behaviour ranging from a benign condition to an aggressive disease with a fatal outcome. We report a case of placental site trophoblastic tumor in 23-year-old women with irregular vaginal bleeding during postpartum lactation period. In addition to persistent low level β-hCG titers, ultrasound examination revealed a suspicious low-echoic area in the myometrium consistent with gestational trophoblastic disease. After histopathological examination of the specimen achieved by ultrasound-guided dilatation and curettage of the uterus, the placental site trophoblastic tumor diagnosis was made and subsequently total abdominal hysterectomy was performed. The patient had an uneventful recovery, and no recurrence was detected for 40 months in the follow-up period.
文摘Gestational trophoblastic neoplasia(GTN) is a rare tumor that originates from pregnancy that includes invasive mole, choriocarcinoma(CCA), placental site trophoblastic tumor and epithelioid trophoblastic tumor(PSTT/ETT). GTN presents different degrees of proliferation, invasion and dissemination, but, if treated in reference centers, has high cure rates, even in multi-metastatic cases.The diagnosis of GTN following a hydatidiform molar pregnancy is made according to the International Federation of Gynecology and Obstetrics(FIGO)2000 criteria: four or more plateaued human chorionic gonadotropin(hCG)concentrations over three weeks; rise in hCG for three consecutive weekly measurements over at least a period of 2 weeks or more; and an elevated but falling hCG concentrations six or more months after molar evacuation. However,the latter reason for treatment is no longer used by many centers. In addition,GTN is diagnosed with a pathological diagnosis of CCA or PSTT/ETT. For staging after a molar pregnancy, FIGO recommends pelvic-transvaginal Doppler ultrasound and chest X-ray. In cases of pulmonary metastases with more than 1cm, the screening should be complemented with chest computed tomography and brain magnetic resonance image. Single agent chemotherapy, usually Methotrexate(MTX) or Actinomycin-D(Act-D), can cure about 70% of patients with FIGO/World Health Organization(WHO) prognosis risk score ≤ 6(low risk), reserving multiple agent chemotherapy, such as EMA/CO(Etoposide,MTX, Act-D, Cyclophosphamide and Oncovin) for cases with FIGO/WHO prognosis risk score ≥ 7(high risk) that is often metastatic. Best overall cure rates for low and high risk disease is close to 100% and > 95%, respectively. The management of PSTT/ETT differs and cure rates tend to be a bit lower. The early diagnosis of this disease and the appropriate treatment avoid maternal death,allow the healing and maintenance of the reproductive potential of these women.
文摘Summary: In order to explore a potential indicator of predicting the occurrence and development of gestational trophoblastic tumor, the expression of c-erbB2 oncogene in human normal placenta, hydatidiform mole and choriocarcinoma was investigated. The expression of c-erbB2 was detected immunohistochemically by monoclonal antibody against the gene on the formalin-fixed paraffin sections of 21 hydatidiform moles, 21 invasive moles, 20 choriocarcinomas and 30 normal placentas. Results showed that the expression level of c-erbB2 was significantly higher in gestational trophoblastic tumor than in hydatidiform mole and normal placenta of midterm and term pregnancy (P<0.05), while there was no significant difference between patients with gestational trophoblastic tumor of stage Ⅲ, Ⅳ and those of stage Ⅰ, Ⅱ. It was demonstrated that overexpression of c-erbB2 may closely associated with malignant transformation of hydatidiform mole, not only providing important insight into pathogenesis of gestational trophoblastic tumor, but also having an important significance for the early diagnosis and early treatment of gestational trophoblastic tumor.
文摘Gestational Trophoblastic Disease encompasses a group of pregnancy-related disorders that derive from the placenta. Taking Leventhal’s Common Sense Model as a starting point, this study aims to investigate how illness perception could influence patients’ psychological adaptation to these rare diseases. Thirty-seven women completed: the Illness Perception Questionnaire-Revised, the Beck Depression Inventory Short Form, the State-Trait Anxiety Inventory, and the Fertility Problem Inventory. Results show that the perception of severe illness consequences significantly predicts the level of anxiety patients reported at the time of questionnaire completion. Furthermore, mental representations of illness present a significant association with infertility-related stress. Specifically, the belief in the efficacy of the treatment results in fewer feelings of discomfort and isolation from family and social context due to infertility-related problems. Since patients’ illness perception was found to have a specific impact on both anxiety and infertility-related stress, this variable should be considered in the planning of a clinical intervention.
文摘From the published data, the present mini-review attempts to answer two fundamental questions about the gestational trophoblastic neoplasms. In addition, it extrapolates the findings to other cancers that produce small amounts of hCG and how a novel therapies could be developed.
文摘Objective: The purpose of this study was to review clinical data of metastasia lesion of gestation trophoblastic tumor (GTT) in abdominopelvic cavity by color Doppler ultrasound. Subjects and Methods: A retrospective analysis of 13 cases of GTT in China was performed. Clinical appearances, serum human chorionic gonadotropin (hCG) levels, sonographic findings, Doppler waveforms, and patient outcomes were followed up. Color Doppler ultrasound was performed to diagnose the presence of GTT, detect metastasia lesion in abdominopelvic cavity, assess disease recurrence, and monitor the efficacy of chemotherapy. Results: Of the 13 patients with GTT, 4 had choriocarcinoma which 3 cases occurred after an abortion, 1 after a year of dilation and suction evacuation for the hydatidform mole. Metastasia lesion in abdominopelvic cavity was detected by color Doppler ultrasound in all cases of choriocarcinoma, among which the metastasia lesion were found at uterine fundus, near uterus, colon and cystic vascular space near the uterus, repectively. 9 cases with an invasive hydatidiforn mole (IHM) occurred after one to three months of dilation and suction evacuation for the hydatidform mole, consistant with the hCG levels markedly elevating. Metastasia lesion in abdominopelvic cavity was also detected by color Doppler ultrasound besides invasive lesion in uterine muscular layer in all cases of IHM, among which 3 cases showed metastasia lesion in cystic vascular space near the uterus, 2 cases were detected in side wall of pelvic cavity, while the rest were found in abdominal cavity, right kidney, colon and near uterus, respectively. Meanwhile, the image of metastasia lesion with IHM was similar to choriocarcinoma’s. And the reticular structure, the cystic vascular space and solid lesion may be showed by ultrasound. The metastasia lesion had abundant flow. Doppler waveforms showed resistive indices of 0.34 (SD 0.07) for metastasia lesion. There was the same lower-impedance as invasive lesion in uterine muscular layer. Except an IHM with the renal metastasia lesion having been followed, abnormal sonographic and Doppler findings in other metastasia disease all disappeared after surgical operation or chemotherapy were successful. Conclusions: Sonography and Doppler imaging were helpful in detecting metastasia lesion in abdominopelvic cavity, and in following the effectiveness of chemotherapy. And it should be taken full examination for GTT by Color Doppler ultrasound in order to avoid mistake.
文摘Gestational trophoblastic neoplasia (GTN) is a hemorrhagic malignancy with highly rapid potential metastasis via hematogenous spreading. Renal metastasis is of infrequent occurrence. Among previous case reports of renal metastasis in GTN, this is the youngest woman presenting a large renal lesion concurrent with pulmonary and brain metastases. Disease remission had been achieved by treatment with combined chemotherapy and whole brain radiation, although acute myeloblastic leukemia (AML) developed later.
文摘Background: Epitheloid trophoblast tumor (ETT) is a tenuous type of gestational trophoblastic disease. Although clinically ETT behave in variable fashion, it is considered as a potentially malignant tumor, fatal malignancy occurs in 10% of the cases. Case and Conclusion: A 41 years old patient, who previously underwent Tompkins operation because of congenital uterine septum was admitted to our clinic due to irregular bleeding. Despite of serum hCG levels under the upper limit of normal, histopathology analysis of D&C obtained endometrial samples confirmed the presence of ETT by immunostainings. Henceforth we performed prompt abdominal hysterectomy and preserved the normal structured ovaries. According to the müllerianosis theory of endometriosis aberrant differentiation or migration could cause spreading of cells throughout the fetal organogenesis of the uterus. These cells in an apoptosis week environment might correlate with the initiation of ETT. As a conclusion we suggest further studies to assess the link between ectopic cells and ETT, to gain a better understanding in the pathomechanism of the tumor.
文摘BACKGROUND Epithelioid trophoblastic tumor(ETT)is a special type of gestational trophoblastic tumor.However,its pathogenesis has been incompletely elucidated.ETT rarely occurs in the ovaries and fallopian tubes,unlike placental site trophoblastic tumor,requiring a histopathological biopsy and immunohistochemistry for further diagnosis.CASE SUMMARY A 29-year-old woman with irregular vaginal bleeding and elevated serum chorionic gonadotropin(β-hCG)levels presented similar symptoms to ectopic pregnancy.Transvaginal ultrasound revealed abnormal echoes of the left adnexa.Postoperatively,the pathology of the left ovary and fallopian tube was reported as ETT.The patient was followed up with regular hCG measurements and ultrasounds.The blood hCG values showed an upward trend 3 mo after the operation and then chemotherapy was prescribed.The current health status is normal.CONCLUSION For women of childbearing age with elevated serumβ-hCG levels,practitioners should consider ETT and be alert to the poor prognosis of the disease.After surgery,the patient’s condition should be closely observed to prevent recurrence and metastasis.Postoperative chemotherapy is only helpful for treating the disease to a certain extent.

文摘Objectives: To evaluate the role of Doppler ultrasound in prediction and follow up during management of gestational trophoblastic neoplasia (GTN). Methods: The study was performed at Oncology Unit, Maternity Hospital, Ain Shams University in the period from November 2015 to December 2018. Forty cases of complete mole, after evacuation and follow up of serum human chorionic gonodotrophin (β-hCG) titre until it reached zero level (group I) and forty post molar GTN cases (group II) were included in the study. Doppler ultrasound of the subendometrial and intramural blood flow was done for all cases of group I and II. Doppler included two dimensional and three dimensional power Doppler indices. Group II received Methotrexate (MTX) and folinic acid in a dose of 8-day MTX-FA regimen. Doppler follow up for six months of group II concurrently with the chemotherapy regimen was done. Results: A statistically significant difference was found between group I and II regarding initial readings of all Doppler parameters. Follow up for 6 months of GTN cases revealed progressive statistically significant decrease of intramural and subendometrial three dimensional power Doppler (3DPD) indices, while there was a significant increase in two dimensional (2D) Doppler parameters. Four cases were resistant to Methotrexate chemotherapy. Cut off values were determined for prediction of GTN. Multivariate analysis revealed that the most predictive parameter was the subendometrial pulsatility index (PI), odds ratio = 10.63 (95% CI: 1.30 - 86.89). The cut-off point for sub-endometrial PI was: 2.05 (AUC, 90%;sensitivity, 88%;specificity, 76%, PPV 78%, and NPV 86%) with a diagnostic accuracy of 87%. To and Fro sign may be considered a pathognomonic intramural ultrasound sign for prediction of GTN chemo-resistance or choriocarcinoma. Conclusion: Cut off values for Doppler parameters can be used for early predication of GTN. Doppler ultrasound indices can be used during follow up of GTN cases concurrently with serum β-hCG to monitor the response to treatment.
文摘Introduction: Gestational trophoblastic neoplasia (GTN), is recognized as the most curable gynaecologic malignancy. However, many cases are resistant to first line chemotherapy. Objective: The aim of the study is to report our 5 years experience in the management of GTN cases with special stress on the chemo-resistant cases. Methods: The study was performed through reviewing the records of 51 patients who were diagnosed as GTN during the period from 1/1/2006 to 31/12/2010 in Mansoura University Hospital, Egypt. Results: Resistance to methotrexate therapy was reported in 15.15% of low risk cases and received etoposide or cisplatinum/etoposide. Sixty percent of high risk cases were resistant to MAC combination and received salvage chemotherapy or hysterectomy. There was significant correlation between patient response and initial B-hCG, as well as WHO risk score (P value = 0.001 in both) but correlations with age, parity, type of antecedent pregnancy, and histopathology were non significant (p = 0.95, 0.53, 0.47& 0.83 respectively). Conclusion: Low risk GTN cases who were resistant to methotrexate monotherapy received etoposide or cisplatinum/etoposide as a second-line therapy. High risk GTN cases who were resistant to MAC combination received second-line combination chemotherapy and/or hysterectomy. WHO risk score and initial B-hCG were correlated to resistance to first line chemotherapy.
文摘Objectives: This study aimed to assess efficacy of intramuscular methotrexate 8-day protocol in the treatment of low-risk gestational trophoblastic neoplasia and also identify prognostic factors associated with treatment failure, necessitating second line chemotherapy. Methods: This study was performed at Gynaecologic and Obstetric Clinic of Dakar Teaching Hospital, the reference Centre of Gestational Trophoblastic Disease in Senegal. At the beginning of 2011, patients were followed according to FIGO’s recommendations. From 2011 to 2014, we diagnosed 88 low-risk gestational trophoblastic neoplasia (GTN) patients (WHO score < 7). Low-risk patients started their treatment with methotrexate (MTX) based on the 8-day protocol consisting of 1 mg/kg MTX in combination with 0.1 mg/kg folinic acid (FA) every other day. Resistance to treatment was the main outcome. We studied the association of different prognostic factors included in the World Health Organisation (WHO) scoring system and resistance to the initial single agent chemotherapy. Results: Eighty-eight patients were diagnosed for GTN during the study period. Average age was 31 years. The antecedent pregnancy was molar in 98.1% of cases. Seventy-four patients underwent remission after single agent-chemotherapy. Resistance rate to single-agent chemotherapy was 15.9% (14 patients). Nine of them achieved remission after second line chemotherapy. WHO score was significantly associated with the risk of resistance to single-agent chemotherapy. Other variables included in the WHO as age, antecedent pregnancy, pre-treatment hCG, tumour size and FIGO stage were not significantly associated with resistance. We report five fatal cases. Conclusion: The 8-day protocol consisting of 1 mg/kg MTX in combination with 0.1 mg/kg folinic acid (FA) every other day is effective for women with LRGTN. The only significant prognostic factor for failure is pretreatment WHO score. We highly recommend the use of this protocol particularly in developing countries where methotrexate is available, affordable and relatively safe.
文摘Objective: To determine whether epidermal growth factor (EGF) and its receptor have any possible correlation with etiology of gestational trophoblastic diseases. Methods: Avidin-biotin immunoperoxidase techniques with polyclonal antibodies against EGF, EGFR were used to examine 53 cases of GTD, including complete hydatidiform mole(16),invasive mole(20),gestational choriocarcinoma(17).Results:EGF was mainly localized on syncytiotrophoblasts (ST), and was found less on cytotrophoblasts. Cytologic localization of EGFR showed the similar results. The positive rate of EGF and EGFR were 0.625, 0.813 in hydatidiform mole, 0.405, 0.450 in invasive mole and 0.118, 0.235 in gestational choriocarcinoma. There was significant difference of EGF or EGFR among hydatidiform mole group and other groups, respectively (P<0.05). Conclusion:The cellular levels of EGF and EGFR decreased gradually in the development of GTD. It implied that the autocrine and paracrine mechanism may play an important role on the proliferation and differentiation of trophoblast cells and the disorder of the system may lead to GTD malignant transformation.
文摘Objective: To evaluate the role of the lung lobectomy in gestational trophoblastic tumor patients with lung metastases. Methods: A total of 45 cases of trophoblastic tumor with pulmonary metastases treated by lung lobectomy from 1985~2002 at PUMC hospital were retrospectively analyzed. Seven cases were diagnosed as invasive mole and thirty-eight as choriocarcinoma. Results: Lung lobectomy was performed in all of these patients after several courses of chemotherapy. Seven cases of invasive mole reached complete remission. Eleven cases of choriocarcinoma with stage Ⅲa had received average 13 courses of chemotherapy, 10 of them reached complete remission. Seventeen cases of choriocarcinoma with stage Ⅲb had received average 14.3 courses of chemotherapy, 11 of them reached complete remission. Ten cases of choriocarcinoma with stage Ⅳ had received average 15 courses of chemotherapy, six of them reached complete remission. In the 45 patients, histologic examination disclosed haemorrhagic necrotic tissue in 27 patients, 17 of them reached complete remission(63%). Histologic examination also revealed fibrosis around the focus in 16 patients, 14 of them reached complete remission(88%). Tuberculosis was found in 2 patients.Conclusions: Although the development of effective chemotherapy has resulted in improved survival of patients with gestational trophoblastic tumor, lung lobectomy remains an important adjunct treatment in a selected subset of patients. Pathological examinations can help to estimate the prognosis.
文摘GTD (Gestational Trophoblastic Disease) is a pathology that encompasses benign and malignant clinical forms, affects women of childbearing age, has a variable incidence and is more frequent in developing or underdeveloped countries, colliding with the economic barrier. The frequent absence of clear protocols and guidelines for the correct diagnosis of the pathology results in inadequate classification, imprecise treatment and failed post-therapeutic observation, increasing the risk of relapses, morbidity and mortality. The present study aims to point out updated national and international practice protocols of diagnosis of GTD, through an integrative review. Seven articles were selected and it was observed that the main international reference centers are agreed with the management suggested by the IFGO (International Federation of Gynecology and Obstetrics), being the conduct in the Hydatidiform Mole (HM): evacuation by suction and curettage under ultrasound guidance, followed by hCG monitoring every 1 - 2 weeks until normalized (usually one month for Partial Hydatidiform Mole six months for Complete Hydatidiform Mole and one year for Gestational Trophoblastic Neoplasia). Unfortunately, regarding the diagnosis of MH, the guidelines of some countries show the absence or difficulty of access to the karyotype test and ploid p57 or pelvic ultrasound accompanying the uterine curettage, contrary to what is proposed by the IFGO guideline. Establishing and complying with consistent guidelines can improve patient care, with early diagnosis of the pathology and its complications, reducing the rate of recurrence, morbidity and mortality, especially in less developed countries.
