[First experience with the modified program NHL-BFM-90 application in adult patients with primary diffuse large B-cell gastric lymphosarcoma with unfavourable prognosis].

AIM: To assess efficacy of a modified program NHL-BFM-90 in adult patients with primary diffuse large B-cell gastric lymphosarcoms (PDLBGL) with unfavourable prognosis. MATERIAL AND METHODS: Modified courses of NHL-BFM-90 were conducted in 5 patients aged 27-67 years from January 2004 to September 2005. Four patients received chemotherapy of the first line, in one patient block therapy followed monotherapy with chlorambucil and a CHOEP course. All the patients were in a severe clinical condition and had several initial factors of unfavourable prognosis: size of the tumor more than 10 cm; stage IE and more advanced; B-symptoms; proliferative activity above 70%. The program NHL-BFM-90 was modified because of the patients' age. Chemotherapy was conducted according to the middle arm of the original program NHL-BFM-90, but methotrexate was introduced in a dose 1 g/m2 for 12 hours, while leukovorin was given 18 hours after the start of methotrexate injection. In two cases the blocks were enhanced with rituximab, 2 patients had doxorubicin in block A, in one case block C was enhanced with methotrexate. A total of 23 modified blocks NHL-BFM-90 were performed: one patient was given 6 blocks, two patients--5, one patient--4 blocks and one patient--3 blocks. RESULTS: Four patients after block 2 and one patient after block 3 of polychemotherapy NHL-BFM-90 achieved remission of the disease of 6 to 22 months duration which still continues. Infectious complications related to hematological toxicity arose more frequently at the latest courses of chemotherapy. CONCLUSION: Treatment according to the modified program NHL-BFM-90 in adult patients with PDLBGL and unfavourable prognosis is highly effective. For a mean follow-up of 10.2 months no recurrences occurred. The number of courses can be reduced to decrease accumulated hematological toxicity and in case of rapid achievement of remission.

[The modified program NHL-BFM-90 in the treatment of patients with diffuse large B-cell lymphosarcoma].

AIM: To investigate efficacy of the modified protocol NHL-BFM-90 in patients with diffuse large B-cell lymphosarcoma (DLBCLS). MATERIAL AND METHODS: A total of 13 DLBCLS patients with stage II-IV of the disease with affection of lymph nodes at the disease onset (nodal lesion) and stage II with tumor size more than 10 cm (bulky disease) received first-line treatment according to the modified program NHL-BFM-90 from 2002 to 2005. The diagnosis was made by WHO criteria. RESULTS: A complete remission was achieved in 76.9% patients. Resistance to therapy was observed in the patients with bone marrow affection. The 2.5-year overall survival was 74%, 2-year event-free survival was 75% (the events were recurrence and resistance). Follow-up continued from 5 to 47 months. CONCLUSION: The efficacy of the modified protocol NHL-BFM-90 in DLBCLS patients with stage III-IV of the "nodal" disease and stage II of the "bulky" disease was high.

[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.

[Prognostic value of a focal bone marrow lesion in diffuse large B-cell lymphosarcoma].

AIM: To study prognostic implications of a focal mature cell lesion of the bone marrow (BM) in patients with diffuse large B cell lymphosarcoma (DBLCL). MATERIAL AND METHODS: 54 patients with histologically confirmed DBLCL were given first-line CHOP and CHOP-like courses from 1996 to 2003. B-cell nature of the tumor was confirmed immunohistochemically, immunophenotypically and with flow fluorimetry. RESULTS: In debute of the disease 16 patients had local involvement of the lymph organs (stage I-II by Enn-Arbor), 21 patients--generalized disease (stage III-IV) and 17 patients--involvement of non-lymphatic organs. Overall 3-year survival in first-line therapy in mature cell lesion of BM was 23%, without it--0%. One-year event-free survival was 34 and 0%, respectively. CONCLUSION: The presence of a focal mature cell lesion of BM in DBLCL patients influences the prognosis. Regarding high frequency of transformation of mature cell lymphoproliferative diseases in DBLCL, focal lesion of BM is an indirect sign of a secondary nature of the disease.
