Abstract
Abstract
Objective: The objective of this study is to evaluate the pattern of care and survival outcome in patients with malignant ovarian germ cell tumors (MOGCTs). Materials and Methods: Between January 2004 and August 2017, 50 patients with MOGCT were identified at Amrita Institute of Medical Sciences and 48 included in analyses. Histologic subtypes were as follows: dysgerminoma 11; immature teratoma 16; yolk sac tumor 3; and mixed germ cell tumor 18. 31 (64.6% patients belonged to Stage I and 17 (35.4%) patients were advanced stage (Stage II-IV). Results: Median follow-up period was 34 months (range: 1–241 months). The 5- and 10-year disease-free survival (DFS) and overall survival (OS) for the entire cohort were 87.5% and 94.4%, respectively. DFS and OS of incomplete surgery Stage I patients 28.6% and 68.6%, respectively, were significantly lower than completely staged patients 100%. Out of 8 incomplete surgery patients, 5 recurred of which 2 died of disease within 4 and 9 months of recurrence. There was no survival difference with comprehensive surgical staging (CSS) and pediatric surgical staging (PSS) in Stage I MOGCT (DFS and OS 100%). Stage I dysgerminoma kept on active surveillance after PSS had equivalent survival of 100%. There was no survival difference in advanced stage MOGCT treated with primary debulking surgery and neoadjuvant chemotherapy (NAC) followed by fertility-sparing surgery (DFS and OS 100%). Conclusion: Incomplete surgery in Stage I MOGCT was associated with poor survival. There was no survival difference with CSS and PSS. NAC followed by surgery could be a reasonable option for patients of advanced stage MOGCT.
