[Treatment of adult Berkitt-like lymphoma].

AIM: To compare programs of chemotherapy used in adult Berkitt-like lymphoma (ABLL); to assess efficacy and toxicity of the protocol AblL-M-04. MATERIAL AND METHODS: 31 ABLL patients (23 males, 8 females, mean age 27 years) participated in the study performed in Hematological Research Center in 1995-2004. ABLL stage I, II, III and IV was diagnosed in 3, 5, 8 and 15 patients, respectively. 10 patients had diffuse large B-cell lymphoma. 9 patients received 2 to 6 courses of CHOP, 1 patient--6 courses of Pro-Mace-Cytabom, 11 patients with newly diagnosed ABLL and 5 pretreated with CHOP--NHL-BFM-90. The modified protocol ABLL-M-04 of intensive short-term therapy included 10 patients, 2 of them pretreated. RESULTS: Of 10 patients given CHOP or CHOP-like courses 9 were resistant to therapy, 2 died of rapid progression, 7 were converted to the program therapy. 5 patients on the protocol NHL-BFM-90 died after short-term improvement. None of them achieved remission. Of 10 patients with newly diagnosed ABLL treated according to NHL-BFM-90 protocol, remission was achieved in 4 patients, follow-up median--34 months (2-56). Six patients died: 4 of progression, 2 of chemotherapy complications. BLL-M-04 therapy was made in 9 patients: 7 patients persisted on the first remission, 2 patients died of chemotherapy complications. Overall duration of the treatment was 3-3.5 months. CONCLUSION: The protocol ABLL-M-04 seems to be more effective than a classic NHL-BFM-90, but this must be supported by more cases. CHOP therapy cannot be recommended for patients with ABLL because of poor efficacy (all the CHOP patients died).

[A CHOP-21 course efficacy in therapy of diffuse large B-cell lymphosarcoma].

AIM: To examine efficacy of polychemotherapy (PCT) CHOP-21 in patients with diffuse large B-cell lymphosarcoma (DLBCL). MATERIAL AND METHODS: Fifty-five DLBCL patients received first-line therapy according to CHOP-21 program in 1996-2004. The diagnosis was made by WHO criteria. RESULTS: Initially, 37 patients had lymph node lesions, 18--nonlymphatic lesions. Complete remissions were achieved in 49% (56.7% in nodal lesions, 33.3% in extranodal ones). Overall 5-year survival was 35%, event-free--25%, for patients with nodal lesions--36 and 32%, respectively, extranodal lesions--35 and 22%, respectively. Overall 5-year and event-free survival in patients with local lesions was 85 and 75%, generalized--25 and 20%, respectively. In patients with involvement of the gastrointestinal tract 3-year overall and event-free survival reached 50 and 45%. Event-free survival was not seen in patients with extranodal lesions of other locations in overall 3-year survival 45%. CONCLUSION: PCT program CHOP-21 was effective in DLBCL patients with local nodular lesions except cases with large-size tumors, invasion in the adjacent organs and tissues and isolated gastric lesion.
