This study was aimed to investigate the clinical experience and management of patients with SCC of the urinary tract. We collected data of patients who were diagnosed with genitourinary SCC (GSCC) between 2002 and 2013 and were treated in the Fudan University Shanghai Cancer Center. A total of 18 patients were diagnosed with GSCC of which 10 originated from the prostate, seven from the bladder and one from the adrenal gland. The mean follow-up time was 15.5 months and progression-free survival (PFS) was 9.3 months. Primary tumor resection was attempted in 13 of 18 patients (72.2%) in whom radical surgery was performed in six of 14 (42.9%) limited disease patients. Most of the patients (13, 72.2%) received cisplatin-based chemotherapy. Patients who had normal lactic dehydrogenase (LDH) levels showed a significantly higher median PFS and overall survival (OS) compared with patients with high LDH levels (P = 0,030, P = 0.010). Patients with limited disease treated with a radical operation experienced a non-significant (P = 0,211) longer PFS compared with patients who were not treated, but this reached statistical significance after analyzing OS (P = 0.211, P = 0.039). Our patients showed a poor prognosis as reported previously. Serum LDH levels beyond the normal range indicate a poor prognosis. For GSCC patients who are diagnosed with limited disease, radical surgery is strongly recommended along with cisplatin-based chemotherapy,展开更多

However, it is of clinical importance because it is one of the most aggressive tumors of the prostate with a very poor prognosis. There exist few artificially cultured tumor cell lines to study SCNCE Then, another approach to that study consists in the use of fresh tumor tissue obtained from patients and its heterotransplantation into host mice. The purpose of this review is to integrate data from more than 20 years of heterotransplantation research in the study of small-cell neuroendocrine carcinoma of the prostate (SCNCP). Heterotransplantation has provided data regarding the histopathology, karyotype, DNA content, cell cycle frequency, tumor markers, androgen receptor expression, metastasis and take rate of this prostate disease. When possible, comparisons between original in situ specimens removed from patients and heterotransplanted tissue from host mice have been made. There are advantages, as well as limitations, that have been identified for SCNCP heterotransplants versus xenotransplantation of cultured cells. Overall, heterotransplanted tumors are better than conventional tumor xenografts at retaining tumor morphology, pathology, secretory activity and expression of tumor markers of the patient's original specimen. Furthermore, heterotransplanted tissue preserves the three-dimensional tumor architecture of the prostate to maintain critical stromal-epithelial cell interactions.展开更多

Here, we examined the effect of Peptide A on the cell proliferation of cell lines of small-cell lung carcinoma, breast cancer, and prostate cancer: RERF-LC-MA, MCF-7, and PC-3, respectively. Peptide A inhibited the proliferation of RERF-LC-MA, but not MCF-7 or PC-3. TCTA protein was immunohistologically detected in RERF-LC-MA and MCF-7. Thus, Peptide A may provide a novel strategy for the therapy of the patients with small-cell lung carcinoma, especially with bone metastasis. In addition, Peptide A may be useful for the treatment of various cancer patients with bone metastasis.展开更多

Streptavidin-biotin peroxidase (SP) immunohistochemical technique was used to detect the expression of Aurora B in 10 cases of normal proliferative phase endometria, 10 cases of normal secretory phase endometria and 72 cases of endometrial carcinomas respectively. According to the 1988 International Federation of Gynecology and Obstetrics (FIGO) grade, there were 37 patients in grade 1, 23 in grade 2 and 12 in grade 3 respectively. According to the FIGO stage, there were 59 patients in stage Ⅰ-Ⅱ and 13 patients in stage Ⅲ-Ⅳ. Aurora B was expressed in both normal proliferative phase endometria, secretory phase endometria and endometrial carcinomas, but its positive labeling index (PLI) in proliferative phase endometria was significantly higher than that in secretory phase endometria (P〈0.01) and endometrial carcinomas (P〈0.01). The PLI of Aurora B was lower in tumors with well differentiation (G1), low surgical staging (Ⅰ-Ⅱ), and ≤1/2 myometrial invasion than that in tumors with moderate and low differentiation (G2--G3), higher surgical staging (Ⅲ-Ⅳ), and 〉1/2 myometrial invasion (all P〈0.01). Aurora B exerts its functions in the replication of normal endometrial glandular cells; Expression of Aurora B is significantly correlated with biologic behavior of endometrial carcinoma, indicating that Aurora B may be a promising prognostic factor in endometrial carcinoma.展开更多

Results In normal endometrium p16 was expressed while cyclin D 1 was almost negative in the proliferative phase,but both of them were negative in the secretory phase.Among the groups of the simple and compound hyperplasia, the atypical hyperplasia and the endometrial carcinoma,the expression of p16 showed a descending tendency, while the expression of cyclin D 1 showed an ascending tendency.In endometrial carcinomas the expression of p16 was significantly lower than that of normal endometrium and proliferative endometrium( P <0.01, P <0.05).However, the expression of cyclin D 1 in proliferate endometrium and endometrial carcinoma was significantly higher than that in normal endometrium ( P<0.05,P<0.01) .The overexpression of cyclin D 1 in the atypical hyperplasia group was obviously different from that in the simple and compound hyperplasia group ( P <0.01).In endometrial carcinoma,the expression of p16 was decreasing with the descending of cell differentiate degree, on the opposite, the expression of cyclin D 1 was increased and there existed a negative correlation between them.It was also observed that the overexpression of cyclin D 1 was significant different between G 1 and G 2,G 3(P<0.01).Conclusion p16 is a negative regulating factor of cell cycle in endometrial carcinoma, while cyclin D 1 is a positive one.Both of them are important in the genesis and development of endometrial carcinoma.The low expression of p16 and the overexpression of cyclin D 1 are related with the malicious biological behaviors of endometrial carcinoma and maybe play an important role in the judgement of prognosis.Overexpression of cyclin D 1 may be an earlier molecular event in the genesis of endometrial carcinoma.展开更多

Methods: To analyze the clinical materials of 47 patients who had undergone an operation with PESC and to compare it with those patients with esophageal squamous-cell carcinoma (ESCC) or primary esophageal adenocarcinoma (PEAC). Results: The overall resectability, morbidity and 30-day mortality rates of PESC were 93.6%, 17.0% and 2.1% respectively, similar to those of ESCC or PEAC. TNM staging and lymph node metastasis were the major determinants influencing long-term survival. Tumor length, depth of tumor invasion and type of operation had little influence on long-term prognosis. The 5-year survival rate of PESC was 7.5%, which was much lower than that of ESCC and PEAC (P<0.01). Among the 42 deceased patents, one died of anastomotic leakage and the others died of remote metastasis and recurrence. Adjuvant chemotherapy did not help improve the patients’ long-term survival. Conclusions: Compared with ESCC and PEAC, PESC is the most malignant type with early lymphatic and hematogenous metastases and poor prognosis. Lymph node metastasis is the major factor influencing the prognosis. Patients in stage 0, I and II a of PESC are indicated for surgical resection, while those in stage II b, III or IV should be managed with non-surgical combined therapy.展开更多

Based on the endometrial cytological findings (suggestive of high grade neuroendocrine carcinoma) showing that there were rosette-like and cord-like structures consisting of small rounded tumor cells with oval nuclei and scanty cytoplasm, radical hysterectomy was performed. Histopathological and immunohistochemical examinations on the operated specimens revealed primary high grade neuroendocrine carcinoma of the endometrium. Despite the extensive treatment against the malignancy, the patient died due to widespread metastases after 5 months after the surgery and autopsied.展开更多

文摘An 84-year-old woman suffered from post-menopausal genital bleeding for 3 months. Based on the endometrial cytological findings (suggestive of high grade neuroendocrine carcinoma) showing that there were rosette-like and cord-like structures consisting of small rounded tumor cells with oval nuclei and scanty cytoplasm, radical hysterectomy was performed. Histopathological and immunohistochemical examinations on the operated specimens revealed primary high grade neuroendocrine carcinoma of the endometrium.
