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
The five-year survival rate for all stages of ovarian cancer is 46%; the one-year survival rate is 72% and the ten-year survival rate is 35%. For cases where a diagnosis is made early in the disease, when the cancer is still confined to the primary site, the five-year survival rate is 92.7%. About 70% of women with advanced disease respond to initial treatment, most of whom attain complete remission, but half of these women experience a recurrence 1–4 years after treatment. Brain metastasis is more common in stage III/IV cancer but can still occur in cancers staged at I/II. People with brain metastases survive a median of 8.2 months, though surgery, chemotherapy, and whole brain radiation therapy can improve survival.
