Methods: Results of full field digital mammography (FFDM) and fine needle aspiration cytology (FNAC) were obtained and analyzed from a consecutive of 102 women with palpable breast masses, results were correlated with the histopathological findings. Results: Of the 102 cases, malignancy was confirmed in 43 cases (42.16%) by final pathological examination, the sensitivity and specificity of cancer detection with FNA cytology was 90.7% (39/43) and 89.8% (53/59), re- spectively, the whole accuracy was 90.2% (92/102), with a positive predictive value of 86.7% (39/45) and a negative predictive value of 93.0% (53/57). FFDM gave a sensitivity of 88.4% (38/43), specificity of 83.1% (49/59), and whole accuracy 85.3% (87/102), the positive predictive value and negative predictive value was 79.2% (38/48) and 90.7% (49/54), respectively. All the FNAC-negative cancer cases were suggestive of malignancy by FFDM findings, however, the benign cases which present as equivocal finding by FNA cytology, could not be ruled out the presence of malignancy. Conclusion: FNAC and FFDM both are accurate, effective and economical diagnostic modalities, combined use of these two methods can reduced the misdiag- nosis rate of breast masses.展开更多

High spatial resolution and the close proximity to the evaluated organs within the mediastinum and abdominal cavity allow detection of small focal lesions and precise tissue acquisition from suspected lesions within the reach of this method. Fine needle aspiration(FNA) is considered of additional value to EUS and is performed to obtain tissue diagnosis. Tissue acquisition from suspected lesions for cytological or histological analysis allows, not only the differentiation between malignant and non-malignant lesions, but, in most cases, also the accurate distinction between the various types of malignant lesions. It is well documented that the best results are achieved only if an adequate sample is obtained for further analysis, if the material is processed in an appropriate way, and if adequate ancillary methods are performed. This is a multi-step process and could be quite a challenge in some cases. In this article, we discuss the technical aspects of tissue acquisition by EUS-guided-FNA(EUS-FNA), as well as the role of an on-site cytopathologist, various means of specimen processing, and the selection of the appropriate ancillary method for providing an accurate tissue diagnosis and maximizing the yield of this method. The main goal of this review is to alert endosonographers, not only to the different possibilities of tissue acquisition, namely EUS-FNA, but also to bring to their attention the importance of proper sample processing in the evaluation of various lesions in the gastrointestinal tract and other accessible organs. All aspects of tissue acquisition(needles, suction, use of stylet, complications, etc.) have been well discussed lately. Adequate tissue samples enable comprehensive diagnoses, which answer the main clinical questions, thus enabling targeted therapy.展开更多

Patients with a clinically solitary thyroid nodule were included in the study group. <strong>Results:</strong> 135 cases of clinically detected solitary thyroid nodules, 126 female and 9 male patients, between 14 - 65 years age, median 41 years and mean 39.76 years, (94, 41) patients respectively Right side thyroid effect more than Left side, Fine needle aspiration cytology (FNAC) sensitivity, specificity and accuracy was (61%, 72%, 64%) respectively. Postoperative histopathology reported 100 (74%) patients as having benign thyroid nodules and 35 patients (26%) as having malignant thyroid nodules. Postoperative transient hypocalcemia was observed in 9 patients (7%), and temporary hoarseness was observed in 3 patients (2%). <strong>Conclusion:</strong> The incidence of malignancy in solitary thyroid nodules is high. Rapid growth by history and hard fixed nodule by examination and hypoechoic, micro calcification and cervical lymphadenopathy on Thyroid Ultrasound frequently in malignant nodules. Male risk factors for thyroid cancer but age, number and size of nodules not included as risk factor. Fine needle aspiration cytology (FNAC) is more helpful for diagnosing if aspiration under Ultrasound guidance and reading by experience histopathologists. The type of surgery depends on preoperative evaluation, including history, examination, ultrasound, fine needle aspiration cytology (FNAC) result, and intraoperative assessment of the nodule. There are fewer complications of thyroid surgery by experienced surgeons.展开更多

Compared with patients with undetectable EBV DNA, patients with detectable preoperative plasma EBV DNA have worse prognosis and may require a more aggressive treatment strategy.展开更多

文摘Background:Currently,the diagnosis and treatment of nasopharyngeal carcinoma(NPC)patients with residual cervical lymphadenopathy following radical radiotherapy with or without chemotherapy are challenging.We investigated the prognosis of NPC patients with residual cervical lymphadenopathy and assessed the diagnostic and prognostic values of Epstein-Barr virus(EBV)DNA in these patients.Methods:This study included 82 NPC patients who were diagnosed with suspected residual cervical lymphadenopathy following completion of antitumor therapy.Their plasma EBV DNA levels were measured using quantitative polymerase chain reaction(qPCR)before the initiation of treatment and before neck dissection.Fine needle aspiration cytology(FNAC)was performed in 21 patients.All patients had undergone neck dissection and postoperative pathological examination to identify the nature of residual cervical lymphadenopathy.The overall survival(OS),progression-free survival(PFS),distant metastasis-free survival(DMFS),and locoregional relapse-free survival(LRRFS)were calculated using the Kaplan-Meier method and compared using the log-rank test.The Cox proportional hazards model was used to calculate hazard ratios(HRs)with 95%confidence intervals(CIs).Multivariable analysis was used to estimate the effect of potential prognostic factors on survival.Results:Following a median follow-up of 52.6 months,compared with patients with negative postoperative pathological findings for residual cervical lymphadenopathy,the patients with positive findings had a significantly lower 3-year PFS rate(49.9%vs.83.3%,P=0.008).Among NPC patients with residual cervical lymphadenopathy,the patients with preoperative plasma EBV DNA>0 copy/mL had a lower 3-year PFS rate than did those with no detectable EBV DNA(43.7%vs.61.1%,P=0.031).In addition,combining FNAC with preoperative EBV DNA detection improved the diagnostic sensitivity.Multivariable analysis demonstrated that residual cervical lymphadenopathy with positive postoperative pathological result was an independent prognostic factor for PFS and that detectable preoperative plasma EBV DNA was an independent prognostic factor for OS.Conclusions: Using FNAC combined with preoperative EBV DNA detection improves the sensitivity in diagnosing NPC with residual cervical lymphadenopathy. Compared with patients with undetectable EBV DNA, patients with detectable preoperative plasma EBV DNA have worse prognosis and may require a more aggressive treatment strategy.
