Granulosa cell tumours of the ovary: demographics, survival and the management of advanced disease.
Ovarian granulosa cell tumours (OGCT) are rare, accounting for only 3%-5% of primary ovarian tumours. As a result of oestrogen production OGCTs tend to present with early stage disease, which has a good prognosis. For patients with advanced disease, surgery and radiotherapy have been the major modalities of treatment. More recently, platinum-based chemotherapy has been shown to have important activity in advanced disease. In this retrospective study, we have reviewed the results of 62 patients who were treated for adult OGCT at the Royal Marsden Hospital between 1969 and 1995, with particular emphasis on the management of advanced disease. The median age at primary diagnosis was 53 years (range 13-77). Sixty-one per cent of these patients had Stage I disease, 21% Stage II disease, 16% Stage III and 2% Stage IV. Stage I patients had a good prognosis with 5- and 10-year overall survival rates of 95% and 90%. Eleven Stage I patients received adjuvant pelvic radiotherapy, with no apparent benefit to recurrent rate or overall survival. Disease progression occurred in 40% of Stage I patients at a median interval of 76 months (range 12-240), and in 62% of the Stage II patients, at a median interval of 31 months (range 2-57). The median interval from progression of Stage I/II disease to death was 22 months (range 3-144). For patients with inoperable disease, radiotherapy produced a number of long-term remissions with an overall response rate of 50%. Platinum-based chemotherapy also appears active, with responses documented in four out of five patients treated with the PVB regimen (cisplatin, vinblastine, bleomycin) as first line therapy. There were no responses documented to non-platinum chemotherapy or to hormonal manipulation. The results from this study confirm the activity of platinum-containing chemotherapy regimens in OGCT and support the need for further trials to optimize the management of this rare tumour.
