Over 80% of patients with epithelial ovarian cancer present with advanced disease, FIGO stage III or IV at the time of diagnosis. The majority require extensive upper abdominal surgery to obtain complete gross resection. This may include splenectomy, distal pancreatectomy, partial hepatectomy, cholecystectomy, and usually diaphragmatic peritonectomy or resection. Following surgery, diaphragmatic hernia-a very rare but serious complication-may occur. We describe four cases of left-sided diaphragmatic hernia resulting after debulking surgery, which included left diaphragm peritonectomy and splenectomy, in patients with advanced ovarian cancer. In association with the current shift towards more extensive debulking surgery for ovarian cancer, more patients may present with postoperative left-sided diaphragm hernia, making the prevention, diagnosis, and management of this complication important to practicing gynecologic oncologists. Intraoperatively the diaphragm should be checked thoroughly to rule out any defects, which should be closed. A diaphragmatic hernia may be easily misdiagnosed because the patient can present with various symptoms. While rare, these hernias require prompt identification, intervention and surgical correction to avoid serious complications.

OBJECTIVE:Gaps in access to appropriate cancer care, and associated cancer mortality, have widened across socioeconomic groups. We examined whether demographic and socioeconomic factors influenced receipt of adjuvant radiation therapy (RT) in patients with high-risk, early-stage endometrial cancer. METHODS:A retrospective study cohort was selected from 349,404 endometrial carcinoma patients from the National Cancer Database in whom adjuvant RT would be recommended per national guidelines. The study included surgically treated patients with endometrioid endometrial cancer with one of the following criteria: 1) FIGO 2009 stage IB, grade 1/2 disease, age ≥ 60 years; 2) stage IB, grade 3 disease; or 3) stage II disease. Logistic regression analysis was performed to identify factors associated with omission of adjuvant RT. Association between adjuvant RT, covariables, and overall survival (OS) was assessed with multivariable Cox proportional hazards models. RESULTS:19,594 patients were eligible for analysis; 47% did not receive adjuvant RT. Omission of adjuvant RT was more prevalent among African-American, Hispanic, and Asian compared to non-Hispanic white patients (OR 0.79, 95%CI: 0.69-0.91; OR 0.75, 95%CI: 0.64-0.87; OR 0.75, 95%CI: 0.60-0.94, respectively). Lower median household income of patient's area of residence, lack of health insurance, treatment at non-academic hospitals, farther distance to treatment facilities, and residence in metropolitan counties were associated with omission of adjuvant RT. Such omission was independently associated with worse OS (HR1.43, p < 0.001). CONCLUSION:Adjuvant RT is omitted in 47% of patients with early-stage, high-risk endometrial cancer, which is associated with poor access to appropriate, high-quality care and worse outcome.
