Treatment of intermediate and advanced stage Hodgkin's disease with modified baseline BEACOPP regimen: a Hellenic Co-operative Oncology Group Study.

The purpose of this prospective phase II trial was to investigate the safety and efficacy of a modified baseline BEACOPP (bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine, procarbazine, and prednisone) regimen in the treatment of intermediate and advanced stage Hodgkin's disease (HD). From October 1997 to November 2001, 51 consecutive, previously untreated patients with stage IIA (bulky), IIB, III, and IV disease were treated with a modified baseline BEACOPP regimen with the etoposide administered i.v. on day 1 and orally at a dose of 100 mg/m2, on days 2 and 3. Each patient was scheduled to receive eight courses of BEACOPP with consolidation radiotherapy to bulky (> or =5 cm) or residual disease. There were 25 males and 26 females with a median age of 32 yr (16-65 yr); 80.3% of the patients had nodular sclerosis HD, 41% had bulky disease (> or =5 cm), 10 were in stage IIA (bulky > or =10 cm), 15 in stage IIB, 19 in stage III, and seven in stage IV. Thirty-seven patients (72.5%) achieved a complete response and 17.6% partial response. No significant difference in overall response rate was observed between patients with: (i) 0-2 vs. > or =3 negative prognostic factors, (ii) in stage II vs. stages III/IV, LDH level, and bulky disease. With a median follow up period of 39.5 months, actuarial 3-yr survival rate is 82% and time to progression rate 72.5%. Treatment with this combination was well tolerated. Grades 3 and 4 leukopenia and neutropenia occured in 26% and 28% of the patients, respectively, whereas in 16.3% of the patients infection was observed. Support with granulocyte colony-stimulating factor was given to 59% of the patients. No case of secondary MDS/leukemia has been observed. The results of the present study demonstrate that the modified baseline BEACOPP regimen with radiotherapy used in our patients was well tolerated and effective therapy for intermediate and advanced stage HD. Further follow up time is required to evaluate long-term toxicity.

Monoclonal gammopathies in B-cell non-Hodgkin's lymphomas.

The association of monoclonal gammopathy (MG) with B-cell non-Hodgkin's lymphomas (NHL) is a well known phenomenon. The aim of the present work was to study the incidence, type of monoclonal component and prognostic significance of MG in a population of 255 cases with B-cell NHL. Among 255 evaluable patients with B-cell NHL, 145 were males and 110 females with a median age of 58 years (range 18-85). There were 166 patients with the various subtypes of aggressive (intermediate/high grade) NHL and 89 with the various subtypes of low risk. MG was detected in 44 patients (17.2%) with a median age of 61 years (range 23-79). There were 22 cases (8.6%) with IgG type (IgG/(k) 15, IgG/(lambda) 7), 4 cases (1.6%) with (IgA/(k) 3, IgA/(lambda) 1) and 18 cases (7.0%) with IgM (IgM/(k) 12 IgM/(lambda) 6). MG was found in 15.6% of the patients with aggressive NHL, while in low risk NHL the incidence was 20.2% (N.S.). The type of MG according to histological classification was as follows: Aggressive NHL: IgG 17 cases, IgA 2 cases, IgM 7 cases: low risk NHL: IgG 5 cases, IgA 2 cases, IgM 11 cases. The distribution of MG according to stage of the disease was as follows: stage I (4.5%), stage II (18%), stage III (6.8%) and stage IV (70.4%). The median survival of patients with aggressive NHL with MG was 17 months compared to 40 months of those without (P=0.22). Similarly the median survival of patients with low risk NHL and MG was 51.5 months compared to 38.5 months of those without (P=0.90). In conclusion MG was detected in 17.2% of cases with B-cell NHL. IgG-MG was more frequent in cases with aggressive NHL, while IgM in cases with low risk NHL. MG was mostly associated with advanced stage and had not any prognostic significance on survival.

T-cell-rich B-cell lymphoma. Analysis of clinical features, response to treatment, survival and comparison with diffuse large B-cell lymphoma.

OBJECTIVES: Clinical features, response to treatment and survival of T-cell-rich B-cell lymphoma (TCRBCL) patients were compared to those of a similar group of patients with diffuse large B-cell lymphoma (DLBCL). METHODS: Between 1992 and 1999, 10 patients with a diagnosis of TCRBCL were treated in our department. Over the same 7-year period, a group of 65 patients with DLBCL were diagnosed in the same department. Both groups of patients were treated with the same anthracycline-based chemotherapy. RESULTS: A significantly higher percentage of patients with TCRBCL presented with B-symptoms, elevated LDH, bone marrow infiltration and disseminated extranodal involvement compared to patients with DLBCL. TCRBCL patients responded poorly to combination chemotherapy, since only 3 of them achieved complete remission (33%) compared to 48 (75%) patients with DLBCL. All patients with TCRBCL who achieved complete response relapsed within the first 2 years while 65% of patients with DLBCL survive disease free for a median follow-up period of 4 years. The median overall survival for DLBCL patients has not been reached yet, while it was 18 months for TCRBCL patients. CONCLUSIONS: Although the number of patients in our study is small, it seems that patients with TCRBCL present with advanced disease, respond poorly to chemotherapy and display a short disease-free and overall survival compared to patients with DLBCL.
