Abstract

Lymphoblastic lymphoma (LBL) is one of predominant childhood non-Hodgkin’s lymphoma (NHL) subtypes. However, excellent outcomes have been achieved with acute lymphoblastic leukemia (ALL)-type treatments in children with LBL.

The purpose of this study was to investigate outcomes children and adolescents with LBL treated with the NHL-BFM 90 and 95 protocols in the Moscow region.

Methods: 58 pts (m, - 40; f, - 18) were enrolled in this study from May 1991 to August 2008. Fifty-two (90%) pts were treated with the ALL-like therapy protocol NHL-BFM 90 or 95 for non-B-NHL (ALL-type) patients, and 6 (10%) –with NHL-BFM 90 for B-NHL. These protocols differed from the original by reduction of the methotrexate dose (1 g/m2/24h instead of 5 g/m2/24h).

Results: The median age at time of presentation was 11.0 (range 1.5–21.6) years. Forty-five (90%) pts have a T -cell immunophenotype. Fifty-three (91%) had advanced (III, IV) stage disease. The presenting sites of T-LBL included mediastinal mass and bone marrow in 35 (78%) and 13 (29%) cases respectively. CR was 94 and 83% for non-B-NHL and B-NHL treatment respectively. Five-year event free survival (5y-EFS) was 0.80 ± 0.06 (median of observation 4.1 years) and 0.67 ± 0.19 (5.1 years) respectively (p > 0.05). Five-year overall survival (5y-OS) was 0.85 ± 0.05 and 0.80 ± 0.06 respectively (p > 0.05). The situation without mediastinal involvement was a factor for an unfavorable prognosis for T-LBL: 5y-EFS –was 0.56 ± 0.17 vs. 0.90 ± 0.05 (p = 0.036). Sex, age, increased LDH, slow or fast therapy response, and involvement of the central nervous system or bone marrow did not affect the prognosis (p > 0.05).

Conclusions: The NHL-BFM 90 and 95 for non-B-NHL protocols are effective therapeutic regimes for pediatric LBL, and the long-term results obtained are comparable with international data.
