The aim of this study was to evaluate whether omentectomy, appendectomy, and peritoneal biopsy should be a routine part of staging surgery in endometrial carcinoma. Data of 97 patients who had been diagnosed with clinical stage I endometrial carcinoma were reviewed. Associations in the data obtained, pelvic and para-aortic lymph node status, depth of myometrial invasion, grade, and histology were investigated. The chi-square (χ2) test was used for statistical analysis.
Of 97 patients, six (6%) had omental metastases, which was microscopic in four. There was a statistically significant relationship between omental metastasis and tumor grade (P < 0.01). Deep myometrial invasion was significantly more common in patients with omental metastases. Tumor was found in one of 55 appendectomy specimens (2%). Omentectomy may be included in surgical staging in patients with deeply invasive or grade 3 endometrial cancer because of the possibility of omental metastasis in spite of what appears to be stage I disease in laparotomy. In other cases, omentectomy and appendectomy and biopsies from peritoneal sites should be performed in the presence of grossly suspicious disease.
