Peritoneal metastasis from gastric cancer is often undetectable by routine imaging studies. Even a microscopic metastasis detected only by cytologic examination of the peritoneal washes denotes a dismal prognosis, and surgery is ruled out as futile for patients who turn out to be cytology-positive by staging laparoscopy. On the other hand, recent developments in cancer chemotherapy have improve...

Peritoneal recurrence after a curative resection of colorectal cancer is less common than lymphatic spread or hematogenous metastasis [1]. Moreover, peritoneal carcinomatosis often develops at a later stage of recurrent disease and is regarded as noncurable. Therefore, being able to predict the possibility of peritoneal recurrence at an early time after the original diagnosis and to prevent its...

Improvement of the treatment results in patients with endometrial carcinoma has been achieved by a multidisciplinary approach including surgery, chemotherapy and radiotherapy, similar to the case for many other carcinomas. Although total hysterectomy/bilateral salpingo-oophorectomy (TH/BSO), pelvic and para-aortic lymphadenectomy and peritoneal cytology are often required, cases with early carc...

Abstract Background The optimal treatment in patients with gastric cancer and peritoneal disease remains controversial. Some guidelines indicate palliative only, while others consider surgical case of positive lavage cytology (CY+) or limited disease. Here, we analyzed the role cancer, prognostic relevance response to neoadjuvant therapy. Methods In this retrospective cohort analysis, adenocarc...

OBJECTIVE The exfoliation of endometrial carcinoma might intraperitoneally spread through the fallopian tube. We analyzed the influence of prior tubal ligation (TL) in endometrial carcinoma to evaluate whether it can prevent the process and improve patients' survival. METHODS A total of 562 patients with a diagnosis of endometrial carcinoma at the Peking University People's Hospital between J...

The aim of this study is to determine the value of surgical staging for the two histologic types (expansile or infiltrative) of apparent stage I mucinous ovarian carcinoma. We retrospectively analyzed patients treated from 1976 and 2016 for apparent macroscopic stage I ovarian mucinous carcinoma. Extra-ovarian disease and tumors that metastasized to the ovaries were excluded. Two expert patholo...

OBJECTIVE The surgical staging system for endometrial carcinoma developed by International Federation of Gynecology and Obstetrics (FIGO) in 1988 was revised in 2009. Given the importance of continuous validation of the prognostic performance of staging systems, we analyzed the disease specific survival for patients with endometrial carcinoma using FIGO 1988 and 2009 systems. Further, the stage...

INTRODUCTION Patients with peritoneal dissemination of pancreatic adenocarcinoma do not benefit from surgical resection, but radiologic and cytologic detection of peritoneal cancer lack sensitivity. This trial sought to determine if an oncolytic virus may be used as a diagnostic agent to detect peritoneal cancer. METHODS Peritoneal washings from patients with pancreatic adenocarcinoma were in...

BACKGROUND The aim of the study was to compare the frequency of positive peritoneal washings in endometrial cancer patients after either hysteroscopy (HSC) or dilatation and curettage (D&C). PATIENTS AND METHODS We performed a retrospective analysis of 227 patients who underwent either HSC (N = 144) or D&C (N = 83) and were diagnosed with endometrial carcinoma at the University Medical Centre...
