Objective Primary ovarian small cell carcinoma of pulmonary type(SCCOPT)is a rare ovarian tumor with a poor prognosis.The platinum-based chemotherapy is the standard treatment.However,there is little research on the clinical characteristics of SCCOPT and the potential benefits of other treatments due to its low incidence.The study aims to investigate clinicopathological characteristics and treatment of SCCOPT.Methods We summarized the clinical,imaging,laboratorical and pathological characteristics of 37 SCCOPT cases,in which 6 cases were admitted to the Gansu Provincial Hospital from the year of 2008 to 2022 and 31 cases reported in 17 English and 3 Chinese literatures.Results The median age of the studied SCCOPT cases(n=37)was 56.00(range,22-80)years.Almost 80%of them had a stageⅢorⅣtumor.All patients underwent an operation and postoperative chemotherapy.Nevertheless,all cases had a poor prognosis,with a median overall survival time of 12 months.Immunohistochemical y,the SCCOPT of all patients showed positive expressions of epithelial markers,such as CD56 and sex-determining region of Y chromosome-related high-mobility-group box 2(SOX-2),and negative expressions of estrogen receptor,progesterone receptor,vimentin,Leu-7,and somatostatin receptor 2.The tumor of above 80%cases expressed synaptophysin.Only a few cases expressed neuron-specific enolase,chromogranin A,and thyroid transcription factor-1.Conclusions SCCOPT had a poor prognosis.SOX-2 could be a biomarker to be used to diagnose SCCOPT. 展开更多

Background: Ovarian clear cell carcinoma (CCC) is often diagnosed at stage I. However, because of the poor prognosis of recurrent cases, even for stage Ia CCC, treatment strategies such as expansion of fertility-sparing treatment and omission of adjuvant chemotherapy have been carefully discussed in recent years. We previously reported the possibility of the maximum standardized uptake value (SUVmax) as a biomarker of CCC prognosis prediction at all stages. In this study, we confirmed differences in SUVmax within stage I CCC and considered treatment strategies. Methods: We selected all 31 patients with ovarian CCC stage I who underwent fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) before treatment between 2006 and 2013 at our institution. This retrospective study was based on their medical records. Results: Clinical tumor stage was Ia in 13 patients, and Ic in 18 (Ic (b) in 11, and Ic (1) + Ic (2) in seven). There were no differences in serum CA125 level, maximum tumor diameter or mural nodules. Median SUVmax was significantly higher in stage Ic (5.87) than stage Ia (3.08) cases (P = 0.02). Progression-free survival was longer in the low SUVmax group than the high SUVmax group (P = 0.08). Conclusions: SUVmax for primary lesions in CCC was significantly higher in stage Ic than stage Ia. As SUVmax represents a prognostic factor in stage I CCC, these findings may suggest SUVmax as an indicator for the application of fertility-sparing surgery and omission of adjuvant chemotherapy for stage Ia CCC. 展开更多
