Objective: The objective was to determine how often peritoneal cytology is positive for malignancy in women with known ovarian cancer. Knowing this fact would help determine the usefulness of diagnostic paracentesis.
Methods: Records of all women diagnosed with invasive epithelial ovarian cancer from 2004 to 2012 were examined to correlate presence of ascites, cytologic, and pathologic findings.
Results: A total of 313 patients were included in analysis. A total of 210 of 313 patients (67.1%) with ascites had cytology positive for malignancy. This left 103 patients with ascites and cancer without malignant cells found in the ascites removed at the time of surgery.
Conclusions: Except in a few cases, paracentesis is not recommended for the diagnosis of ovarian cancer because of the potential spreading of cancer. Furthermore, with only just over two thirds of cases of known cancer and ascites having cytology positive for malignancy, the value of paracentesis for diagnosis of ovarian cancer is minimal.
