Absolute monocyte count in follicular lymphoma patients treated with rituximab plus cyclophosphamide,doxorubicin, vincristine,and prednisone

Elevated absolute monocyte counts (AMCs) have been reported to indicate poor prognosis for patients with lymphoproliferative disease, including those with follicular lymphoma (FL) receiving various treatments. We evaluated the prognostic impact of AMC in 150 consecutive FL patients who received rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) therapy. Progression-free survival (PFS) did not differ significantly according to the AMC level. Univariate and multivariate analyses did not indicate a prognostic significance of AMC for PFS. Thus, the AMC is not a prognostic factor for FL patients treated with R-CHOP. However, immunochemotherapy might influence the prognostic impact of AMC.

Liposome-encapsulated doxorubicin in combination with cyclophosphamide, vincristine, prednisone and rituximab in patients with lymphoma and concurrent cardiac diseases or pre-treated with anthracyclines

BACKGROUND: To assess the efficacy and safety of the combination of non-pegylated liposome-encapsulated doxorubicin (Myocet(R)) with cyclophosphamide, vincristine, prednisone and rituximab (R-COMP) in patients with aggressive non-Hodgkin's B-cell lymphomas. METHODS: Twenty-one patients were selected for the presence of negative concurrent clinical features such as cardiac comorbidity and/or previous treatment with anthracycline-based regimens. Liposome-encapsulated doxorubicin at a dose of 50 mg/m(2) was administered in association with cyclophosphamide (750 mg/m(2)), vincristine (1.4 mg/m(2)), prednisone (40 mg/m(2)) and rituximab (375 mg/m(2)) every 21 days for four to six cycles unless progression or unacceptable toxicity occurred. RESULTS: A complete response (CR) was obtained in 16/21 patients (76%), three patients achieved a partial response (14%), with an overall response rate of 90%. Two patients (10%) did not respond to therapy. After a median follow-up of 13 months (range 2-36 months), 2/16 CR patients relapsed, with a disease-free survival (DFS) of 78%. CONCLUSIONS: The replacement of doxorubicin with its non-pegylated liposomal pharmaceutical analogue was well tolerated and highly effective in inducing remission in this group of patients at high risk for cardiac toxicity or previously treated with anthracyclines. Its high tolerability and low incidence of cardiac events (only one patient) warrants further studies to confirm the clinical benefits of liposomal doxorubicin in this subset of patients.     

Activity of rituximab plus cyclophosphamide, doxorubicin/mitoxantrone, vincristine and prednisone in patients with relapsed MALT lymphoma

BACKGROUND: Various chemotherapeutic agents as well as the anti-CD20 antibody rituximab (R) have been tested in patients with mucosa-associated lymphoid tissue (MALT) lymphoma, but no standard chemotherapeutic regimen has emerged so far. Judging from the data obtained in various types of lymphoma, the activity of R appears to be enhanced by combination with chemotherapy. As no data on this topic exist for MALT lymphoma, we have retrospectively analysed our experience with R plus cyclophosphamide, doxorubicin/mitoxantrone, vincristine and prednisone (R-CHOP/R-CNOP) in patients with relapsed MALT lymphoma. PATIENTS AND METHODS: A total of 26 patients were identified, 15 were administered R-CHOP while 11 patients were given R-CNOP due to age >65 years or pre-existing cardiac conditions. Cycles were repeated every 21 days, and restaging was performed after 4 cycles of therapy. In case of complete remission, 2 further cycles were administered for consolidation while patients achieving partial remission or stable disease after restaging were given 4 further courses. RESULTS: A total of 170 cycles were administered to our patients (median 6, range 2-8). Twenty of the 26 patients (77%) achieved a complete remission and 6 (23%) a partial remission. Toxicities were mainly haematological, with WHO grade III/IV leukocytopenia occurring in 5 patients. After a median follow-up of 19 months (range 10-45), all patients are alive: 22 are in ongoing remission, while 4 have relapsed between 12 and 19 months after treatment. CONCLUSIONS: Our data demonstrate a high activity of R-CHOP/R-CNOP in relapsing MALT lymphoma irrespective of prior therapy.     

Rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone with or without radiotherapy in primary mediastinal large B-cell lymphoma: the emerging standard of care

More aggressive treatment approaches (methotrexate, cytarabine, cyclophosphamide, vincristine, prednisone, and bleomycin [the MACOP-B regimen] or consolidation with high-dose therapy and autologous stem cell transplantation) have been considered to be superior to cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in patients with primary mediastinal large B-cell lymphoma (PMLBCL). Rituximab-CHOP (R-CHOP) is the standard of care for diffuse large B-cell lymphoma, whereas efficacy in PMLBCL has not been adequately confirmed.

Patient and Methods.

Seventy-six consecutive PMLBCL patients who received R-CHOP with or without radiotherapy (RT) were compared with 45 consecutive historical controls treated with CHOP with or without RT. Baseline characteristics of the two groups were balanced.

Results.

The rate of early treatment failure was much lower with R-CHOP with or without RT (9% versus 30%; p = .004). The 5-year freedom from progression rate after R-CHOP with or without RT was 81%, versus 48% for CHOP with or without RT (p < .0001). The 5-year event-free survival rates were 80% and 47% (p < .0001) and the 5-year overall and lymphoma-specific survival rates were 89% and 69% (p = .003) and 91% and 69% (p = .001), respectively, with only seven of 76 lymphoma-related deaths. Among R-CHOP responders, 52 of 68 received RT.

Conclusions.

Based on these results, most patients with PMLBCL appear to be cured by R-CHOP in 21-day cycles with or without RT, which could be the current standard of care. Therefore, the need for more aggressive treatment strategies is questionable unless high-risk patients are adequately defined. Further studies are required to establish the precise role of RT.     

原发性骨淋巴瘤诊疗现状及进展

原发性骨淋巴瘤是一种罕见的结外淋巴瘤,缺少特征性的临床症状和影像学表现。化疗、放疗或联合治疗是原发性骨淋巴瘤患者常用的治疗方法。原发性骨淋巴瘤预后优于其他结外淋巴瘤。文章就原发性骨淋巴瘤的临床表现、病理诊断、治疗方法进行综述,以加深对原发性骨淋巴瘤的理解。
