Background: Ovarian adult granulosa cell tumours are low-grade malignant sex cord–stromal neoplasm with a low recurrence rate. Prognostic factors for recurrence include tumor stage, tumor rupture in Stage I neoplasms and the presence of residual tumors after surgery. However, in recurrent tumors, prognostic factors for overall survival (OS) are lacking. In the present paper, we conducted a systematic meta-analysis with the aim to assess prognostic factors for OS in patients with recurrent GCT. Methods: Electronic databases were searched for all studies assessing prognostic factors in recurrent adult granulosa cell tumor of the ovary. Student T test, Fisher’s exact test and Kaplan–Meier survival analysis with long-rank test were used to assess differences among groups; a p value < 0.05 was considered significant. Results: Eleven studies analyzing 102 recurrent tumors were included in the systematic review. Tumor stage and localization of recurrent tumors were significantly associated with OS on Kaplan–Meier analysis; Cox regression analysis showed a HR of 0.879 for the stage II, of 3.052 for the stage III, and of 2.734 for stage IV tumor was significantly associated with OS (p = 0.037); observed HRs for abdominal and thoracic locations were of 2.405 and of 4.024, respectively. Conclusions: In conclusion, the present article emphasizes the prognostic significance of tumor stage > II and extrapelvic anatomic sites of recurrences in patients with recurrent granuolase cell tumors of the ovary.

Abstract

Background: Ovarian adult granulosa cell tumours are low-grade malignant sex cord–stromal neoplasm with a low recurrence rate. Prognostic factors for recurrence include tumor stage, tumor rupture in Stage I neoplasms and the presence of residual tumors after surgery. However, in recurrent tumors, prognostic factors for overall survival (OS) are lacking. In the present paper, we conducted a systematic meta-analysis with the aim to assess prognostic factors for OS in patients with recurrent GCT. Methods: Electronic databases were searched for all studies assessing prognostic factors in recurrent adult granulosa cell tumor of the ovary. Student T test, Fisher’s exact test and Kaplan–Meier survival analysis with long-rank test were used to assess differences among groups; a p value < 0.05 was considered significant. Results: Eleven studies analyzing 102 recurrent tumors were included in the systematic review. Tumor stage and localization of recurrent tumors were significantly associated with OS on Kaplan–Meier analysis; Cox regression analysis showed a HR of 0.879 for the stage II, of 3.052 for the stage III, and of 2.734 for stage IV tumor was significantly associated with OS (p = 0.037); observed HRs for abdominal and thoracic locations were of 2.405 and of 4.024, respectively. Conclusions: In conclusion, the present article emphasizes the prognostic significance of tumor stage > II and extrapelvic anatomic sites of recurrences in patients with recurrent granuolase cell tumors of the ovary.
