Task: Answer Verification
Input (English): Question: Is epithelial ovarian tumors in the reproductive age group : age an independent prognostic factor?
Answer: Epithelial ovarian cancer patients age 30 years or younger have a more favorable prognosis because of a higher rate of early stage, low grade tumors. Patients aged 31-40 years also show a more favorable disease profile and clinical outcome, although to a lesser extent, than the average ovarian cancer population. Age does not emerge as an independent prognostic factor for ovarian carcinoma in women younger than 40 years.
Output (English): no
