Abstract. Al-Badawi I, Brasher PMA, Ghatage P, Nation JG, Schepansky A, Stuart GCE. Postoperative chemotherapy in advanced ovarian granulosa cell tumors.
The objective of this research is to assess the use of first-line postoperative chemotherapy in patients with advanced ovarian granulosa cell tumor (GCT). A retrospective population-based case series identified 60 women with stage IC or greater ovarian GCT over a 25-year period. Five patients were excluded because of incomplete information. None of the patients had received chemotherapy or radiotherapy prior to the diagnosis of advanced GCT. All patients had, at a minimum, a total abdominal hysterectomy and bilateral salpingo-oophorectomy. Pathology was centrally reviewed and the diagnosis confirmed. Of the 55 eligible patients, the 21 women with stage III and IV disease were the main focus of the study. Clinical outcomes and survival were compared between 13 women who received combination chemotherapy and eight who did not. Univariate analysis was conducted to assess the impact of age at diagnosis, size of residual disease, and adjuvant use of radiation therapy on prognosis. For the 55 patients, median age at diagnosis was 54 years (range 22–79). Median length of follow-up was 4.4 years (range 0.3–23.3). Median time to progression was 2.3 years (range 0.3–5.3). Sixty percent of those with no macroscopic disease after primary surgery recurred within 4.5 years of diagnosis. All patients with gross residual disease (>2 cm) were dead within 4 years of diagnosis. Overall 5 years survival rate was 61.6% (95% CI (49.3–76.9)). Among stage III and IV patients, there were no differences with respect to age at diagnosis and use of radiation therapy between those who did and did not receive chemotherapy. The only statistically significant difference was the presence of macroscopic residual disease (82% vs. 22%). Although there was no statistical significant difference in overall survival, there was a trend toward a poorer outcome in the group that received chemotherapy. Survival of patients with macroscopic residual disease was not influenced by use of chemotherapy (P = 0.976). We conclude that the presence of macroscopic residual disease after primary surgery was the most important prognostic factor. Although these patients were more likely to receive postoperative chemotherapy, there was no evidence to document a beneficial effect of systemic therapy in this group of women.
