摘要: Despite a number of basic and clinical studies, it is still very difficult to improve the prognosis patients with high-grade astrocytoma. However, recent success procarbazine, N-(2-chloroethyl)-N'-cyclohexyl-N-nitrosourea vincristine (PCV) chemotherapy for oligodendrogliomas that have lost chromosomes 1p 19q has encouraged authors evaluate biological behavior brain tumors by means genetic analysis. Both disorders p53/MDM2/p14(ARF) p16(INK4a)/RB signaling pathways been found play an essential role in tumorigenesis various tumors. Herein, summarize alterations mainly focusing on two appear affect significantly patient prognosis.
