Vorinostat
A recent study suggested that vorinostat also possesses some activity against recurrent glioblastoma multiforme, resulting in a median overall survival of 5.7 months (compared to 4–4.4 months in earlier studies). Further brain tumor trials are planned in which vorinostat will be combined with other drugs.
Ovarian cancer
Ovarian cancer survival varies significantly with subtype. Dysgerminomas have a very favorable prognosis. In early stages, they have a five-year survival rate of 96.9%. Around two-thirds of dysgerminomas are diagnosed at stage I. Stage-III dysgerminomas have a five-year survival of 61%; when treated with BEP chemotherapy after incomplete surgical removal, dysgerminomas have a 95% two-year survival rate. Sex-cord-stromal malignancies also have a favorable prognosis; because they are slow-growing, even those with metastatic disease can survive a decade or more. Low malignant potential tumors usually only have a bad prognosis when there are invasive tumor implants found in the peritoneal cavity.
