Studies on non dysgerminomatous tumors suggest, an early stage minimal residual tumor after the initial surgery, less than 100 ml of ascites, platinum-based chemotherapy, an AFP level less than 1,000 kU/L, and a non-EST histology were found to be significantly related to a more favorable prognosis (12, 17, 19, 22, 23). The gene discussed is AFP; the disease is neoplasm.
