Include criteria | (1) Histologically or cytologically proven B-cell malignancies, either Burkitt lymphoma or B-AL (=Burkitt leukaemia = L3-AL) or diffuse large B-cell NHL or aggressive mature B-cell NHL non other specified or specifiable. (2) Stage III with elevated LDH level, (LDH > twice the institutional upper limit of the adult normal values) or any stage IV or B-AL. (3) 6 months to less than 18 years of age at the time of consent. (4) Males and females of reproductive potential must agree to use an effective contraceptive method during the treatment, and after the end of treatment: during twelve months for women, taking into account the characteristics of rituximab and during five months for men, taking into account the characteristics of methotrexate.

Prior therapy (5) Past or current anti-cancer treatment except corticosteroids of less than 7 days duration in total. (6) Exclusion criteria related to rituximab 6-1)Tumor cell negative for CD20 (absence of result due to technical problems in the presence of other characteristics suggestive of BL/DLBCL, including genetic and phenotypic features, is not an exclusion criteria). 6-2) Prior exposure to rituximab. 6-3) Severe active viral infection, especially hepatitis B. 6-4) Severe infection (such as sepsis, pneumonia, etc.) should be clinically controlled at the time of registration.
