Phase II Trial of Procarbazine, Lomustine, and Vincristine as Initial Therapy for Patients With Low-Grade Oligodendroglioma or Oligoastrocytoma: Efficacy and Associations With Chromosomal Abnormalities

Abstract

PCV produces tumor regressions in a meaningful proportion of patients with LGO/LGOA. Toxicity, especially myelosuppression, is significant. Loss of 1p and 19q seems limited to patients with pure LGO and is inversely related to p53 alterations.
