Multiple peritoneal cytologies collected during laparotomy for gynecologic malignancy.
Review of an 18-mo experience with peritoneal cytology specimens showed that 760 peritoneal washings and 177 diaphragmatic smears were collected during 300 laparotomies on patients known to have or suspected of having gynecologic malignancy. One hundred three patients were eventually shown to have benign gynecologic disease. The remaining 197 procedures were done on patients undergoing primary operations for gynecologic malignancy or laparotomies for previously treated gynecologic malignancy. Of the 197 laparotomies for gynecologic malignancies, 168 had washings separately collected from multiple intra-abdominal sites, and these fluids were interpreted as either all positive or all negative in all but seven (4%) patients. The location and extent of the gross or microscopic disease did not correlate with the site of positive washings. Only three of the 177 diaphragmatic smears were positive for malignant cells; these were collected from three patients undergoing primary treatment of ovarian carcinoma, two of whom had extensive peritoneal involvement by carcinoma. Only 35 of the 197 patients with gynecologic malignancy had positive peritoneal cytologies; 32 of these patients had gross or microscopic peritoneal involvement by malignancy, and one additional patient had metastatic carcinoma in pelvic lymph nodes. The analysis of multiple peritoneal washings separately collected from various intra-abdominal sites and the analysis of diaphragmatic smears collected in the absence of gross diaphragmatic disease appear to be of benefit in few cases.
