Hi,
The information provided by you is insufficient to determine if you will benefit from adjuvant chemotherapy. We need stage, grade, and histopathology information. Please discuss with your doctor your exact stage of disease.
The accepted recommendations are as below:
Patients with pure immature teratoma of the ovary (stage IA, grade 1) have been shown in studies to have 5-year survivals higher than 90%. In this set of patients, there is no evidence to suggest that chemotherapy improves outcome. Patients with immature teratoma (stage IA, grade 2 and 3) have a higher relapse rate and postoperative chemotherapy using a combination of three drugs called the "BEP" regimen should be recommended.
