Summary

GOELAMS LLC98 is a prospective randomized trial comparing in previously untreated B and C Binet stages B-CLL and on an intent to treat basis two strategies. Conventional chemotherapy consisted of six monthly courses of CHOP, followed by 6 CHOP courses every other 3 months in case of response. Experimental arm consisted of high dose therapy with autologous CD34+ purified progenitor cell support, used as consolidation of Complete Remission or Very Good Partial Response obtained after 3 monthly courses of CHOP, followed by 3 to 6 monthly-courses of fludarabine in case of insufficient response.

Detailed description

The aim of the prospective randomized GOELAMS LLC 98 trial reported here was to compare two therapeutic strategies in previously untreated B and C Binet stages B-CLL patients less than 60 years old. Conventional chemotherapy (Arm A) consisted of six monthly courses of CHOP, i.e. vincristin IV 1 mg/m2 on day 1, doxorubicin IV 25 mg/m2 on day 1, cyclophosphamide (Cy) 300 mg/m2 and prednisone 40 mg/m2 both given orally from day 1 to day 5, followed by 6 CHOP courses every other 3 months in case of response. Fludarabine (25 mg/m2 /d IV for 5 consecutive days) was used in case of non response (stable disease or progression) after 3 CHOP courses. This conventional therapy was compared to high dose therapy with autologous CD34+ purified progenitor cell support (Arm B), used as consolidation of Complete Remission (CR) or Very Good Partial Response (VGPR, defined by \>50 % tumoral response and bone marrow lymphocyte infiltration \<30%) obtained after 3 monthly courses of CHOP. In the absence of CR or VGPR, 3 to 6 monthly-courses of fludarabine were performed before mobilization with Cy 4 g/m2 + G-CSF administration. The conditioning regimen included TBI 12 Gy and Cy 60 mg /kg /d for 2 days.
