Prognostic Factors of Granulosa Cell Tumors: A Retrospective Study in a Tertiary Care Cancer Centre of Eastern India

Background and Aims The main objective of this study was to analyze the clinicopathological profile and prognostic factors of granulosa cell tumor (GCT). Method All the cases of ovarian cancer which were seen at our institute between January 2000 and December 2017 were reviewed. Data were analyzed with failure-free survival (FFS) as the primary end point. Results GCTs consisted of 2.66% of all ovarian cancers at our institute. The median age was 43 years. Majority of the patients (62.5%) were unstaged. Six patients (25%) had a fertility-preserving procedure. Forty two percent of the patients received adjuvant chemotherapy. Thirty eight percent of the patients developed recurrence. Considering tumor-related prognostic factors, there was a statistically significant decrease in FFS with the presence of hemorrhage ( p = < 0.001), larger tumors ( p = 0.042), and juvenile variant ( p = 0.002). On the contrary, when treatment-related factors were considered, there was no statistically significant improvement in FFS with the performance of lymphadenectomy ( p = 0.218), omentectomy ( p = 0.453), fertility sparing surgery ( p = 0.152), or administration of adjuvant chemotherapy ( p = 0.45). Conclusion Inherent tumor-related biological factors tend to play a more important role compared with treatment-related factors in GCTs. Hence, the traditional practice of performance of extensive staging procedures and routine adjuvant chemotherapy should be reviewed. Fertility-preserving surgery appears safe to be offered in early stages when desired. Although it is common knowledge that GCTs tend to be hemorrhagic tumors, this factor has not been well recognized as a prognostic indicator till date. Our study sheds some light on this aspect. Since these tumors have a tendency toward late recurrences, a long follow-up is prudent.
