title: CHOD/BVAM regimen plus radiotherapy in patients with primary CNS non-Hodgkin's lymphoma.
abstract: OBJECTIVE
  To assess the efficacy and toxicity, including long-term neurotoxicity, of combined therapy with the CHOD/BVAM regimen given before cranial radiotherapy in the treatment of primary CNS lymphoma (PCNSL).
  
  
  METHODS
  Thirty-one consecutive patients with PCNSL were treated with one cycle of cyclophosphamide, doxorubicin, vincristine, and dexamethasone (CHOD) and two of carmustine (BCNU), vincristine, cytosine arabinoside, and methotrexate (BVAM), followed by cranial radiotherapy (45 Gy whole brain plus a 10-Gy boost for single lesions). The median age was 59 years (range 21-70) and 39% had poor performance status. The median follow-up of patients was 4.1 years (range 2.7-9.0).
  
  
  RESULTS
  Twenty-one patients had no PCNSL at the end of treatment. The 5-year actuarial probability of survival was 31% (95% confidence interval [CI]: 11%-57%), with a median survival of 38 months. Patients < 60 years had a survival significantly longer than those > or = 60 years (4-year survival: 58% (95% CI: 34-82%) vs. 29% (95% CI: 5-53%), respectively; p = 0.04). Two patients died during chemotherapy from pulmonary embolism and bronchopneumonia, respectively, with no evidence of PCNSL at the autopsy. Dementia probably related to treatment occurred in 5 (62%) of the 8 patients 60 years and older, and 4 of them died without evidence of relapse of PCNSL. Dementia correlated with developing brain atrophy and leuco-encephalopathy on serial CT or MR scans.
  
  
  CONCLUSIONS
  This regimen can be given with the planned dose intensity to patients aged less than 70 years, and produces better survival than that reported with radiotherapy alone; however, dementia occurs in the majority of patients aged 60 years of age or more.
