RESUMEN
AIM: To evaluate the efficiency of high-dose therapy according to the DLBL-CNS-2007 protocol in patients with testicular diffuse large B-cell lymphoma (DLBL). SUBJECTS AND METHODS: Out of 408 male patients with non-Hodgkin lymphoma, 8 patients aged 50 to 69 years (median age 55.5 years) with primary testicular (n=3) or with generalized-stage testicular DLBL (n=5) were included in the study. These patients were followed up at the Hematology Research Center, Ministry of Health of the Russian Federation, in 2007 to 2013. Systemic chemotherapy was performed in accordance with the DLBL-CNS-2007 protocol. RESULTS: The DLBL-CNS-2007 protocol was implemented in first-line therapy in 7 patients. At the first diagnostic stage, one patient was found to have anaplastic seminoma; in this connection right orchifuniculectomy was carried out, followed by radiotherapy applied to the scrotal region in a total focal dose of 34 Gy. This patient with disease recurrence was included in the DLBL-CNS-2007 treatment protocol. The number of polychemotherapy (PCT) cycles (n=4 or 6) was determined by the time to achieve complete remission. After completion of DLBL-CNS-2007 PCT, 6 patients achieved complete remission; the primary resistant disease was noted in 2 cases. At this moment 6 patients are alive in first complete remission during the median follow-up of 50 months (10-54 months). CONCLUSION: The findings suggest that high-dose therapy according to the DLBL-CNS-2007 protocol in patients with testicular DLBL can achieve complete remission and increase overall and event-free survival rates. This fact should be borne out by a large number of observations.

AIM: To make a differential diagnosis of diffuse large B-cell lymphoma (DLBCL) with primary involvement of the mediastinal lymph nodes (LN) and primary mediastinal large B-cell lymphoma (PMLBCL); to evaluate the efficiency of a modified NHL-BFM-90 (M-NHL-BFM-90) program in the treatment of the above nosological entities. SUBJECTS AND METHODS: The investigation enrolled 60 patients with large B-cell lymphoma (LBCL) with primary involvement of mediastinal LN who had been treated at the Hematology Research Center, Ministry of Health of Russia, in 2004 to 2012. The diagnosis of PMLBCL and DLBCL with primary involvement of mediastinal LN was based on histological findings, the phenotype of tumor cells, and molecular evidence. Treatment was performed according to the M-NHL-BFM-90 program. Three pregnant women received predelivery polychemotherapy (PCT) according to the VACOP-B protocol and continued to have a DexaBEAM chemotherapy regimen 3-4 weeks postpartum. In case of a residual mass, all the patients underwent consolidation radiotherapy to the mediastinal area in a total focal dose of 36 Gy. RESULTS: The diagnosis of PMLBCL was established in 39 patients: 10 men and 29 women whose ages were 18 to 60 years (median age 30 years); DLBCL with primary involvement of mediastinal LN was verified in 21 patients: 8 men and 13 women whose age was 21 to 70 years (median age 30 years). After m-NHL-BFM-90 treatment protocol, 5-year overall survival rates in the patients with DLBCL with primary involvement of mediastinal LN and in those with PMLBCL were 95+/-5 and 86+/-6% and 5-year event-free survival rates were 95+/-5 and 78+/-7%, respectively. All the pregnant women diagnosed with PMLBCL who had received the VACOP-B --> delivery--> Dexa-BEAM PCT regimen during pregnancy achieved remission. The follow-up periods were 30, 36, and 42 weeks. CONCLUSION: The patients with new-onset LBCL and primary involvement of mediastinal LN are a heterogeneous group that includes patients having two different diagnoses: PMLBCL and DLBCL. The efficiency of high-dose PCT is different in the patients with DLBCL with primary involvement of mediastinal LN and in those with PMLBCL (in spite of their similar clinical features, similar epidemiological characteristics, and the presence of the same unfavorable prognostic factors at onset).

AIM: To ascertain indications to standard (CHOP-21/R-CHOP-21) and intensive (mNHL-BFM-90) treatment in patients with diffuse large B-cell lymphosarcoma (DLBCL) with involvement of lymphoid organs. MATERIAL AND METHODS: The trial, performed from January 2002 to December 2010, enrolled 139 DLBCL patients with affected lymph nodes (LN), tonsils, spleen, bone marrow (BM). The diagnosis was made according to WHO criteria. The patients were examined according to the protocol of lymphoproliferative diseases. Biopsy material from all 139 patients was studied immunohistochemically on paraffin blocks (LN, tonsils, spleen, BM) using a wide panel of antibodies. The same examinations of BM were made in all 18 cases of BM involvement. Cytogenetic examination was performed in 106 patients: 48 standard cytogenetic tests, 139 - FISH for t (14;18) as well as rearrangement of locus 3q27. Patients with a poor prognosis (n = 86, 61.8%) received intensive therapy according to mNHL-BFM-90 program. The signs of a poor prognosis were the following: massive tumor (tumor size more than 7.5 cm), invasion into the adjacent organs or tissues, stage III-IV disease by Enn-Erbor, high concentration of LDG. Patients without a poor prognosis (n = 53, 38.2%) received standard treatment CHOP-21 (n = 28) or R-CHOP-21 (n = 25). RESULTS: A complete remission without recurrences was achieved in all 53 patients without signs of unfavourable prognosis (100%). Overall 5-year survival was 96%, 2 patients died in remission of other causes. Of 86 patients with a poor prognosis a complete remission was achieved in 64 (74.4%) patients. Overall and recurrence-free 5-year survival was 65 and 86%, respectively. CONCLUSION: Standard treatment provided long-term complete remission in all the patients without poor prognosis. Intensive (mNHL-BFM-90) treatment produced the best results in generalized lesion without BM involvement. Overall 5-year survival was 84% in these patients and 12% in patients with BM involvement.

AIM: To analyze the causes of prolonged hematopoietic tissue aplasias in patients with acute leukemias (AL) after chemotherapy courses. MATERIALS AND METHODS: Data on 7 patients with acute myeloid leukemia, followed up at the Hematology Departments, Hematology Research Center, Russian Academy of Medical Sciences, over the period 2003 to 2007, who had developed deep bone marrow aplasia (BMA) inadequate to cytostatic drug exposure during chemotherapy, were analyzed. The authors compared in all the patients the values of peripheral blood and bone marrow (BM) puncture specimens and the results of blood tests using the polymerase chain reaction at different AL development stages with the results of an immunohistochemical study using the markers of viruses of hepatitis C and B, a herpes group (EBV, CMV, HSV-1, HSV-2) and parvovirus B19. RESULTS: The marker of hepatitis C was detected in 6 of the 7 patients with prolonged BMA; 3 of these 6 patients showed a simultaneous infection with hepatitis B. Six of the 7 patients were found to have concomitant BM lesion with various herpes group viruses. Two patients had a resistant form of AL. CONCLUSION: Hepatitis C virus infection in patients and the resistant form of the disease were the principal causes of the development of BMA inadequate to cytostatic drug exposure. Affliction of abundant bone marrow cells with herpes group viruses was not a direct cause, but might substantially aggravate BMA.

AIM: To diagnose diffuse large B-cell lymphosarcoma (DLBCLS) with primary involvement of the mediastinal lymph nodes (LN) and to evaluate the efficiency of aggressive polychemotherapy (PCT). SUBJECTS AND METHODS: The study included 15 patients (6 men and 9 women aged 18 to 70 years; median 38 years) followed up at the Hematology Research Center, Russian Academy of Medical Sciences, in 2004 to 2009. Three and 12 patients had Stages II and IE DLBCLS, respectively. B symptoms were found in 14 (93.4%) patients. Increased lactate dehydrogenase (LDH) concentrations were detectable in 14 (93.4%) patients; tumors of 10 cm or more (bulky disease) were seen in 11 (73.3%). Enlarged cervical, supraclavicular, and axillary lymph nodes were found in 9 (60%) patients; lung involvement via extension in 9 (60%), and invasion into the pericardium in 5 (33.3%) and soft tissues of the anterior thoracic wall in (13.3%). There were no signs of involvement of extranodal organs at the moment of diagnosis. All the 15 patients received PCT according to the modified NHL-BFM-90 program: 4 to 6 courses depending on the response to the therapy; 10 (66.6%) and 5 (33.3%) patients had 4 and 6 courses, respectively; for consolidating purpose, 11 (78.5%) patients were prescribed radiotherapy applied to the mediastinum in a cumulative dose of 36 Gy due to the fact that they had a residual mass. RESULTS: Thirteen (86.6%) patients achieved a complete remission (CR). Primary PCT resistance was confirmed in one case. Another patient was stated to have near-complete remission. No recurrences were notified during the follow-up. The mean CR duration was 24.5 (range 2-49) months. CONCLUSION: DLBCLS with primary LN involvement is an individual nosological entity to be differentiated from primary mediastinal large B-cell lymphosarcoma. In most cases, DLBCLS shows signs of a poor prognosis, which makes it necessary to perform aggressive PCT.

AIM: To compare efficacy and toxicity of conservative therapy (different programs of polychemotherapy) of gastric lymphosarcoma conducted for the last 10 years in Hematological Research Center of the Russian Academy of Medical Sciences. MATERIAL AND METHODS: The study included 63 patients (40 females and 23 males aged 14 to 78 years, mean age 49 years) with primary diagnosis of gastric lymphosarcoma (GL). Of them, 56 (89%) patients had diffuse large B-cell lymphosarcoma (DLBCL) and 7 (11%) had gastric Berkitt's lymphoma (BL). Only detection of t(8;14) with rearrangement of c-myc gene provided accurate diagnosis of gastric BL. By the treatment DLBCL patients were divided into two groups: 44 patients of group 1 received polychemotherapy (PCT) according to CHOP scheme or in combination with radiotherapy and surgical treatment; 12 patients of group 2 were treated according to modified program mNHL-BFM-90, without surgical or radiation treatment. Of 7 patients with gastric BL 5 patients received treatment according to a modified program mNHL-BFM-90 and 2 patients were given CHOP because of DLBCL misdiagnosis without cytogenetic detection of t(8;14). RESULTS: Overall survival in group 1 was 73% in mean follow-up 61 months. The survival depended only on initial factors of poor prognosis (PPF): tumor size over 10 cm, Ann-Arbor stage higher than IE, B-symptoms, elevated level of LDH. Overall survival of 18 gastric DLBCL patients without PPF reached 94%, of 26 patients with PPF - 60%. Lethality due to side effects was 4% (2 patients), primary resistance was 14% (6 patients), recurrence arose in 9% (4 patients). Overall survival in group 2 was 100% in mean remission duration 18 months, was unrelated to PPF (10 of 12 patients) but correlated with high toxicity. 5 BL patients treated with a modified mNHL-BFM-90 program achieved remission (a mean follow-up at present is 1 to 50 months, mean 24 months). 2 BL patients treated with CHOP died for a year. CONCLUSION: Gastric lymphosarcomas are sensitive to chemotherapy, thereby PCT only is effective in most patients. PPF in gastric DLBCL were responsible for poor outcome in 40% patients in CHOP treatment. The modified program mNHL-BFM-90 can produce up to 100% complete long-term remissions in therapy of gastric lymphosarcoma in adults both in BL and DLBCL patients. A cytogenetic examination of c-myc gene rearrangement is obligatory before initiation of PCT of gastric lymphosarcoma.

AIM: To compare efficacy of NHL-BFM-90 and CHOP-like courses in the treatment of anaplastic large cell lymphoma (ALCL). MATERIAL AND METHODS: Twenty-two patients with ALCL participated in the study. The diagnosis was made basing on the findings of clinical, device, morphological, immunohistochemical and molecular-genetic examinations with application of a panel of monoclonal antibodies to CD30, ALK, CD3, CD4, CDS, CD7, CD34, CD15, CD68, CD20, CD45RO, CD45RA, Ki-67. 14 cases of 22 were negative by kinase of anaplastic lymphocytes (ALK-) and 8 were positive (ALK+). Mean age of ALK-ALCL patients was 39.6 +/- 4.1 years, of ALK+ALCL patients - 23.4 +/- 2.6 years. 14 patients were treated by the protocol NHL-BFM-90, 8 were initially treated with other schemes (CHOP, MACOP-B, BEACOPP and others). All 14 patients treated according to NHL-BFM-90 had ALCL stages III-IV with B-symptoms. 12 patients who completed treatment by the above protocol achieved complete remission after the forth course, 2 patients failed the treatment. Of 8 ALCL patients treated initially according to other schemes, a complete remission was achieved in 4 patients (2 had stage II). One of 4 patients with remission had recurrence. Four patients who had failed to achieve complete remission died of the disease progression. CONCLUSION: ALCL occurs more frequently in young and middle-aged patients. The disease has an aggressive course with rapid generalization. For such processes it is more preferable to use a modified protocol NHL-BFM-90.

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).
