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.
Epithelioid sarcoma
The 5-year survival rate for epithelioid sarcoma patients is 50-70%, and the 10-year survival rate is 42-55%. Children with epithelioid sarcoma tend to have slightly better outcomes than adults, with 5 year survival rates around 65%. Pediatric patients also tend to display less lymphatic spread and metastasis. In addition to stage and grade of the tumor, gender, site, age at diagnosis, tumor size and microscopic pathology have all been shown to affect prognosis. Advanced stage and grade are associated with worse outcomes. Females tend to have more favorable outcomes than males, proximal cases show worse outcomes than distal cases, and younger age is associated with more positive outcomes. Tumors more than 2 cm in diameter and tumors with necrosis and vascular invasion have been correlated with a worse outcome.
