To describe the clinical course and outcome of patients with non-surgically-treated advanced ovarian cancer attending a single institute.


We reviewed the medical charts of all patients with advanced epithelial ovarian cancer who underwent chemotherapy at a tertiary medical center between January 2005 and December 2010 but were never operated. Data on patient characteristics, disease course, and outcome were collected from patient files. Sixteen patients met the inclusion criteria. Eight (50%) were diagnosed with apparent FIGO stage IIIC disease, and 8 with stage IV. Five patients (31%) achieved a complete clinical response, and 11 (69%) achieved a partial response. Among the complete responders, the median disease-free interval was 8 months (range 7-11 months). In all of them, the disease recurred and second-line chemotherapy was administered. Of them, four (80%) achieved a second complete response. Partial responders had up to four lines of chemotherapy, with continued disease progression. The median overall survival of the whole group was 19.5 months, and of the complete responders, 28 months.


Most patients with advanced ovarian carcinoma who will not undergo surgery respond only partially to first-line chemotherapy. Having no surgery is associated with a short disease-free interval.
