Does synchronous endometrioid endometrial cancer have any prognostic effect on Stage I endometrioid ovarian cancer?

OBJECTIVE: To determine the effect of synchronous endometrial endometrioid cancer (SEEC) on the prognosis of patients with Stage 1 endometrioid ovarian cancer (EOC). STUDY DESIGN: Clinicopathological data of cases with Stage 1 EOC from January 2000 to November 2013 were retrieved from the computerized database of Etlik Zubeyde Hanim Women's Health and Research Hospital. Of the 31 patients included in the study, 15 patients had primary synchronous endometrial and ovarian cancer (SEOC) (Group 1) and 16 patients had EOC alone (Group 2). RESULTS: Ovarian cancer substage and grade were compared between the two groups, and no significant differences were found. Most of the patients with SEEC had Grade 1 tumours (n=13, 86.7%). In Group 1, nine (60.0%) patients had endometrial tumours with superficial myometrial invasion, and six (40.0%) patients had deep myometrial invasion. Median follow-up was 94 months. Ten-year disease-free survival rates were 92.9% for Group 1 and 84.6% for Group 2 (p=0.565). CONCLUSION: Patients with Stage 1 EOC have excellent long-term survival. The presence of SEEC does not influence the prognosis of patients with Stage 1 EOC, even in the presence of deep myometrial invasion.

Synchronous Ovarian and Endometrial Endometrioid Adenocarcinoma Presenting with Nonbacterial Thrombotic Endocarditis and Pulmonary Thromboembolism: Adenocarcinoma with Thrombotic Events.

Introduction. Nonbacterial thrombotic endocarditis (NBTE) is a rare manifestation of hypercoagulability in patients with malignant neoplasms. Case Report. A fifty-six-year-old woman presented to the emergency service; the clinical workup revealed deep vein thrombosis in right leg and bilateral massive PTE. As the abdominal sections on the spiral CT revealed a giant pelvic mass of ovarian origin, she was referred to our hospital's gynecologic oncology department. She was scheduled for surgery under enoxaparin. She described numbness on one side of her face. Cranial imaging findings revealed acute ischemic cerebral lesions and transesophageal echocardiogram showed vegetation on the aortic cusp. Under anticoagulation treatment, she underwent hysterectomy with bilateral salpingo-oophorectomy and infracolic omentectomy. After tumor resection, her neurological symptoms dissolved with aggressive anticoagulant treatment. Pathology result was synchronous endometrial and ovarian adenocarcinoma. Discussion. NBTE is a rare condition often associated with advanced malignancies. Peripheral embolism and venous thrombosis are complications that have been associated with NBTE due to hypercoagulable state. These disorders could be resistant to routine anticoagulant treatment. In case of a thrombotic complication due to ovarian malignancy, surgical resection of the primary tumor may increase the effect of anticoagulant treatment.

Diagnostic accuracy of intraoperative consultation (frozen section) in borderline ovarian tumours and factors associated with misdiagnosis.

The objective of our study was to evaluate the accuracy of frozen section (FS) in borderline ovarian tumours (BOT) and to define the factors associated with misdiagnosis during FS evaluation. We performed a retrospective review of patients who underwent exploratory laparotomy for an adnexal mass, from January 2007 to July 2012, at a tertiary oncology centre in Turkey. Patients with a diagnosis of BOT either in FS or in permanent pathology were identified. Agreement between FS diagnosis and permanent histology was observed in 37/59 patients (62.7%), which gave a sensitivity and a positive predictive value of 71.2% and 84.1%, respectively. In patients with a diagnosis of BOT by frozen section only (n = 44), the diagnosis was consistent with permanent histopathology in 37/44 patients (84.1%). Frozen section interpreted a malignant tumour as BOT (under-diagnosis) in 6/44 (13.6%) of cases and interpreted a benign lesion as BOT (over-diagnosis) in 1/44 (2.3%) of cases. Slide review of discrepant cases revealed that major pathological causes of under-diagnosis were misinterpretation and sampling errors. Univariate analysis showed that presence of bilateral tumour and positive peritoneal cytology were associated with under-diagnosis. We concluded that, despite significant risk of under-diagnosis, FS analysis is an accurate method for intraoperative diagnosis of BOTs.
