Hodgkin disease in children: results of a prospective randomized trial in a single institution in Argentina (original) (raw)

Medical and …, 1997

Abstract

To compare prospective treatment strategies in childhood Hodgkin disease to the following subsets of patients: a) Favorable prognostic group: these patients were randomized to receive 6 vs. 3 CVPP chemotherapy cycles without radiotherapy (CVPP: cyclophosphamide, vinblastine, procarbazine, and prednisone. The scheme was repeated every 28 days). b) Intermediate prognostic group: these patients were randomized to receive 6 cycles of CVPP or AOPE (AOPE: Adriamycin, vincristine, prednisone, and etoposide). Between the third and fourth cycles, all patients in this group received radiotherapy (RT)(30-40 Gy to initially involved areas). c) Unfavorable prognostic group: those patients received a single arm regimen of 6 cycles of CCOPP/CAPTe (3 of each combination) every 28 days. All these patients received radiotherapy (30-40 Gy to initially involved areas). From October 1987 to December 1994, a total of 114 children and adolescents were evaluated. Mean age was 9 (range 2-17) years. There were 72 boys and 42 girls. With a median follow-up of 5 (range 1.5-8.7) years, at 80 months event-free survival (EFS) and overall survival (OS) for the whole cohort are 0.809 (SE: 0.04) and 0.873 (SE: 0.04), respectively (SE: Standard Error). Favorable prognostic group (n = 26) EFS is 0.831 (0.09) (Arm CVPP x 3:0.857 (0.13) and Arm CVPP x 6: 0.875 (0.08); p = non significant). Intermediate prognostic group (n = 64) EFS is 0.806 (0.05) (Arm CVPP x 6 + RT: 0.872 (0.05) and Arm AOPE x 6 + RT: 0.667 (0.10); p = 0.04). Unfavorable group (n = 24) EFS is 0.829 (0.07). Results of treatment for the whole group are satisfactory. However, 3 cycles of CVPP without radiotherapy obtain equal EFS than 6 cycles without radiotherapy in the favorable prognostic group. In the intermediate prognostic group, 6 cycles of CVPP plus radiotherapy obtain a superior EFS than 6 cycles of AOPE plus radiotherapy. With the success of treatment for Hodgkin disease in children, future research needs to be focused in reducing toxicity without altering the excellent actual outcome.
