Primary central nervous system lymphoma: a role for adjuvant chemotherapy

Abstract

Sixteen immunocompetent patients, 10 of whom were previously reported, with primary non-Hodgkins lymphoma of the central nervous system (PCNSL) were treated and followed longitudinally by the Neuro-oncology Service at the University of California, San Francisco (UCSF) and the University of California, San Diego (UCSD). After undergoing surgery (biopsy or resection), these patients received radiation therapy (RT) with hydroxyurea (HU) followed by adjuvant chemotherapy with the combination of procarbazine, CCNU, and vincristine (PCV) as previously reported. All patients ultimately died of progressive recurrent PCNSL. Toxicity using the HU + RT followed by PCV schedule was tolerable. Median and quartile survival data (41 and 65 months, respectively) suggest efficacy for this chemotherapy schedule and further emphasizes a role for adjuvant chemotherapy in the primary treatment of PCNSL.
