[Long-term results of treatment for T-cell lymphoblastic lymphomas].

AIM: To define the efficiency of the GMALL 2002 program for the treatment of patients with T-cell lymphoblastic lymphomas (T-LBL).

SUBJECTS AND

METHODS

Twenty-five patients with a verified diagnosis of T-LBL were examined. Male/female ratio was 19:6; median age was 33 (range 16-67) years. There was a preponderance of patients with the generalized stages of the diseases: 2, 5, and 18 with Stages II, III, and IV, respectively. Mediastinal lesion was found in 20 (80%) of the 25 patients. Their treatment was performed according to the GMALL 2002 program and similar CHOP courses. Analysis was made in 2 groups that were not different in their clinical and morphological characteristics. Group 1 consisted of 17 of the 25 patients treated according to the GMALL programs; Group 2 comprised 8 patients who had similar CHOP and other chemotherapy regimens.

RESULTS

In Group 1, 15 (88%) patients achieved a complete clinical and hematological remission and 2 (12%) patients died in the first stages of the treatment. No relapses were noted. The median survival had not been achieved; 5-year overall survival was 88 +/- 8%. In Group 2, three patients were alive; 2 completed their treatment; 5 (63%) patients died from treatment failures. The median survival was 23 +/- 18%; 5-year overall survival was 45%.

CONCLUSION

The findings suggest that the GMALL 2002 programs are highly effective in treating patients with T-LBL at the first stage of treatment.
