Background: Endometrial cancer currently represents the most frequent gynecologic malignancy in Western countries, and the seventh most common cancer in women. For advanced-stage disease, the recurrence risk is high, and the site of the relapse is heterogeneous with localized or spread peritoneal disease. There are few therapeutic strategies, and the quality of life is poor. Cases Presentation: We present 3 cases of peritoneal-spread recurrences of endometrial cancer in patients with advanced stage at diagnosis. The patients had been subjected to multiple lines of chemotherapy including re-challenging with platinum regimens, pegylated liposomal doxorubicin, and taxane, with progression of disease. These patients came to us with abdominal distension, dyspnea, elevated CA 125, and presence of ascites. After paracentesis with a single administration of intraperitoneal chemotherapy based on carboplatin, all 3 patients showed improvement in their quality of life and breathing as well as reduction of fatigue and anorexia. No complications occurred. Conclusion: Although only 3 cases are reported, the exceptional results and the absence of side effects observed strongly warrant future trials to investigate the role intraperitoneal chemotherapy can have both as palliative treatment of refractory ascites and as salvage therapy in advanced endometrial cancer.

Introduction: Neuroendocrine tumors (NETs) are a heterogeneous group of malignancies with various clinical presentations and growth rates. NET incidence has been estimated to 2.5–5 per 100,000 people per year, and NET prevalence is 35 per 100,000. They are frequently associated with synchronous or metachronous second primary malignancies (SPM). Methods: We retrospectively reviewed our institutional database on NET patients. We report on 30 patients with NETs and SPMs from a series of 262 patients with NETs: 10 patients with synchronous NETs (33.3%) and 20 with metachronous SPMs (66.6%). Results: The median patient age was 67 years. Of the 10 synchronous lesions, 50% were observed in the GI tract. The most common locations of these lesions were the colon (15%) and pancreas (25%). In 2 patients, there was an association of prostate neoplasia with a subsequent NET of the pancreas. Conclusions: Only few studies have examined the association between NETs and SPMs. Our study showed that the risk of second cancer following NETs is increased. In this single-institution retrospective review, our incidence of additional malignancies in patients with NET was 11.4%. [ABSTRACT FROM AUTHOR]
