OBJECTIVE The purpose of this study was to assess whether peritoneal cytology has prognostic significance in uterine cervical cancer. METHODS Peritoneal cytology was obtained in 228 patients with carcinoma of the uterine cervix (International Federation of Gynecology and Obstetrics [FIGO] stages IB1-IIB) between October 2002 and August 2010. All patients were negative for intraperitoneal dise...

BACKGROUND This study was undertaken to evaluate the long-term prognostic significance of conventional peritoneal cytology in patients with advanced colorectal carcinoma after curative resection. METHODS A review was performed of 189 patients who underwent curative resection for pT3/T4 carcinoma of the colon and upper/middle rectum between March 1987 and December 1991. Patient outcomes were r...

PURPOSE The role of peritoneal washing cytology in determining further treatment strategies after surgery for gastric cancer remains unclear. One reason for this is the fact that optimal procedures to increase the accuracy of predicting peritoneal metastasis have not been established. The aim of this study was to evaluate the efficacy of cytology using samples harvested from two different abdom...

The International Federation of Gynecology and Obstetrics (FIGO) changed the surgical staging criteria for endometrial cancer in 2009, namely combining FIGO 1988 Stage IA and IB in FIGO 2009 Stage IA, eliminating cervical glandular involvement from Stage II, and removing peritoneal cytology as criteria from Stage IIIA (3). This review of the literature sheds light on the continued debate among ...

BACKGROUND Peritoneal lavage cytology in the staging of pancreatic cancer is not widely used given improvements in computed tomography (CT). The aim of this study was to determine the utility of peritoneal lavage cytology in predicting survival in locally advanced pancreatic cancer. METHODS Between 2000 and 2008, 202 patients with biopsy-proven pancreatic cancer who were determined by pancrea...

PURPOSE Peritoneal lavage cytology is part of the routine staging workup for patients with advanced gastric cancer. However, no quality assurance study has been conducted to show variations or biases in peritoneal lavage cytology results. The aim of this study was to demonstrate a test execution variation in peritoneal lavage cytology between investigating surgeons. MATERIALS AND METHODS A pr...

The aim of this study was to evaluate the dissemination of cancer cells at laparoscopic hysterectomy according to the intraperitoneal cytology.Patients with endometrial cancer underwent total laparoscopic modified radical hysterectomy. Peritoneal wash cytology was performed on entering the peritoneal cavity before surgical preparation and just after hysterectomy.Seventy-eight patients underwent...

PURPOSE In colorectal cancer, the role of detecting free malignant cells from peritoneal lavage is currently unclear. In this study, we investigated the positive rate of free malignant cells in peritoneal lavage fluid and their predictive value for prognosis and peritoneal recurrence after a curative resection. METHODS From October 2009 to December 2011, in a prospective manner, we performed ...
