Background:
The long-term survival of patients with advanced stage aggressive lymphoma has not improved significantly during the last twenty years. In a randomised trial, the efficacy of MACOP-B, a six-drug weekly chemotherapy regimen, was compared to CHOP, the current standard regimen, in terms of overall and failure-free survival, toxicity and health related quality of life.
Patients And Methods:
Four hundred five patients with aggressive lymphoma, stage II-IV, age 18-67, were randomised to receive either 12 weeks of MACOP-B or 8 courses of CHOP over 24 weeks. Special emphasis was put in the definition of Ann Arbor stage in extranodal disease. A subset of 95 patients also entered a quality of life study, based on the EORTC QLQ-C30.
Results:
Thirty-one patients were ineligible. Among the remaining 374 patients, the median age was 52 years. According to the age-adjusted International Prognostic Index, 37% were 'high-intermediate' or 'high-risk' patients. No difference could be demonstrated, either in overall survival (60% at five years in the MACOP-B group and 59% in the CHOP group) or in failure-free survival (47% at five years with MACOP-B and 44% with CHOP). In terms of quality of life, physical function and global quality of life were more impaired in patients receiving MACOP-B, who also exhibited more non-haematological toxicity.
Conclusion:
No superiority of MACOP-B compared to CHOP could be demonstrated. CHOP remains the treatment of choice in low-risk patients. At present, intensified or experimental treatment should be reserved for high-risk disease.
