Abstract

In a prospective multicenter therapy trial the remission-inducing potential of the COP-BLAM (5 courses) and the possibly not cross-resistant IMVP-16 (2 courses) regimen for advanced diffuse large cell lymphomas were investigated. Inadequately responding patients were switched early after 2-3 courses to the IMVP-16 protocol. Between January 1986 and August 1988 349 previously untreated patients were recruited who fulfilled the entry criteria: age 15-75 (mean 56 years), stage II-IV. A first restaging after 3 courses of chemotherapy was documented for 280 cases, a second restaging following 7 courses of chemotherapy or a final report was available for 221 patients, 130 of which where in CR (59%). These figures include 29 cases who died already during induction-chemotherapy of progressive disease (n = 17) as well as of therapy-related complications in CR (n = 12). Thirty-three patients were switched early to IMVP-16 due to incomplete response at the first restaging; 13 of those achieved CR by the new regimen (39%), 9 achieved a partial remission which was turned into CR by additional radiotherapy in 5 cases. Dose reductions and interval prolongations were necessary at increasing rates with subsequent chemotherapy courses (20-50% of the cycles). Relapses have occurred in 32 patients so far (14 early, 18 after stop of treatment). The median survival was 24 months (n = 309 patients). These data show that this treatment strategy is effective in a large unselected group of patients of relatively high age. However, patients showing only delayed response with this protocol probably need more aggressive regimens to obtain durable remissions.
