The records of 94 patients with epithelial ovarian carcinoma of low malignant potential were examined. These records were contributed by Walter Reed Army Medical Center, Naval Hospital, Bethesda, MD, and Naval Hospital, Portsmouth, VA. A review of microscopic sections from each of the 94 tumors confirmed that these were lesions of low malignant potential. The tumors occurred in patients of a younger age than that generally described for invasive epithelial ovarian carcinoma. Forty-seven of 94 patients had stage I disease. The corrected five- and ten-year survival rates were 95 and 87%, respectively. Adjunctive postoperative therapy may not influence survival.
