Background: Pelvic (non-uterine) high-grade serous carcinomas (PHGSC) including ovarian, tubal and primary peritoneal serous carcinomas have increased death: incidence ratio due to presentation at advanced stage, rapid progression, poor prognosis and high morbidity. Ambiguity regarding their pathogenesis and lack of a proper screening method is the cause of their late detection and high fatality rate. This study was undertaken to assess the fallopian tube for the presence of precursor lesions in pelvic serous carcinoma...

Synchronous endometrial and ovarian (SEO) carcinomas involve endometrioid neoplasms in both the ovary and uterus at the time of diagnosis. Patients were traditionally classified as having independent primary SEO lesions or as having metastatic endometrioid carcinoma. Recent studies have supported that SEO tumors result from the dissemination of cells from one organ site to another. However, whether this can be considered a "metastasis" or "dissemination" remains unclear. In this report, we performed whole-exome sequencing of tumor samples from a woman with well-differentiated endometrioid SEO tumors and a clinical "recurrent" poorly differentiated peritoneal tumor that was diagnosed 8 years after the complete resection of the SEO tumors...

Primary peritoneal carcinoma is usually advanced at diagnosis and curability is low unless the patient has a small tumor burden. Peritoneal carcinoma can occur in association with hereditary breast and ovarian cancer syndrome, which is thought to account for 5-6% of all breast cancer. Mutations of two breast cancer susceptibility genes, BRCA1 and BRCA2, are responsible for hereditary breast and ovarian cancer. Women with BRCA1/2 mutations often undergo risk-reducing salpingo-oophorectomy (RRSO) to prevent both ovarian and breast cancer...

We report 3unusual cases of cancer of unknown primary(CUP)with a long-term survival after chemotherapy. A 56-yearold man was diagnosed as having CUP with invasion of an enlarged carcinoma 20 cm in size to the pancreas and peritoneal dissemination. He received chemotherapy with paclitaxel, carboplatin, and gemcitabine. After the chemotherapy, CT scan and PET-CT revealed no evidence of disease, so tumor resection was performed. The subsequent pathological findings revealed no cancer and a complete pathological response...

We have read with great interest the article by Illán et al.1 entitled "Long survival in a patient with metastatic colorectal carcinoma: reality or utopia?" This article describes the case of a 42 year old patient with mucinous-type colon adenocarcinoma who had tumor recurrence with peritoneal metastases 18 months after resection of the primary tumor and adjuvant chemotherapy. After multiple metastasectomies and several lines of chemotherapy, the patient died 27 months after the recurrence.

Serous tubal intraepithelial carcinoma is considered the precursor lesion of high-grade serous carcinoma, and found in both low-risk and high-risk populations. Isolated serous tubal intraepithelial carcinomas in patients with BRCA1/2 mutations are detected in ∼2% of patients undergoing risk-reducing bilateral salpingo-oophorectomy and even with removal of the tubes and ovaries the rate of developing primary peritoneal carcinoma following remains up to 7.5%. Postoperative recommendations after finding incidental STICs remain unclear and surgical staging, adjuvant chemotherapy, or observation have been proposed...

The metastatic spread of breast carcinoma to the stomach is rare. There are a small number of previous studies that report metastases from the breast to the stomach and these provide limited information regarding this infrequent event. Consequently, the clinicopathological features, clinical outcomes and the optimal treatment for these patients remain to be elucidated. In the present study, 78 cases of gastric metastases from breast cancer, including the current case, were identified from previous studies between 1960 and 2015...

Vaginal cancer is a rare gynecological malignancy, mainly treated by radiotherapy and surgery. However, the effect of neoadjuvant chemotherapy on patients with vaginal cancer has not been extensively evaluated. The aim of the present study was to assess the feasibility and efficacy of irinotecan and cisplatin in the management of patients with vaginal squamous cell cancer (SCC). Two patients with International Federation of Obstetrics and Gynecology (FIGO) stage I and one patient with FIGO stage II vaginal SCC were treated with irinotecan (240 mg) and cisplatin (100 mg) every 3-4 weeks...

Despite being the largest part of the human gastrointestinal (GI) tract, the small intestine accounts for only 1-1.4% of all GI malignancies. Adenocarcinoma is the most common primary small bowel malignancy, with the most common site being the duodenum. On the other hand, squamous cell carcinoma (SCC) of the duodenum is extremely uncommon. We report the first case of mixed adenocarcinoma and SCC occurring in the third part of duodenum (D3). Our patient, a 64-year-old female with history of GERD, hypertension, and IDDM presented with 4 weeks of nausea, vomiting, and abdominal pain...

Distinguishing malignant peritoneal mesothelioma (MPM) from serous carcinoma involving the peritoneum remains a diagnostic challenge, particularly in small biopsy and cytology specimens. In this distinction, PAX8 expression has been regarded as a specific marker of serous carcinoma. In addition, BAP1 loss is reportedly specific to MPM, in the distinction from both benign mesothelial lesions and ovarian serous tumors (OSTs). Using immunohistochemistry, we examined PAX8 and BAP1 expression in 27 MPMs, 25 cases of benign mesothelium, and 45 OSTs...

The prognosis of advanced temporal bone cancer is poor, because complete surgical resection is difficult to achieve. Chemoradiotherapy is one of the available curative treatment options; however, its systemic effects on the patient restrict the use of this treatment. A 69-year-old female (who needed peritoneal dialysis) presented at our clinic with T4 left external auditory canal cancer and was treated with cetuximab plus radiotherapy (RT). The primary lesion showed complete response. The patient is currently alive with no evidence of disease two years after completion of the treatment and does not show any late toxicity...
