Fludarabine, cyclophosphamide and mitoxantrone in relapsed or refractory chronic lymphocytic leukemia and low grade non-Hodgkin's lymphoma

A regimen combining fludarabine, cyclophosphamide and mitoxantrone (FCM) was used to treat 29 patients with relapsed or refractory chronic lymphocytic leukemia (CLL, N = 24) and low-grade non-Hodgkin's lymphoma (NHL, N = 5) based on evidence suggesting synergism between the 3 drugs. Patients were treated with mitoxantrone 5mg/m2 i.v. day 1 only, fludarabine 25 mg/m2 i.v. for 3 days or 24 mg/m2 orally for 5 days, cyclophosphamide 250 mg/m2 i.v. for 3 days or 150 mg/m2 orally for 5 days inclusive. Eighteen patients had previously received fludarabine and most were heavily pretreated with 40% having >2 prior treatments. A median number of 4 FCM courses (range of 1-9) were given. The response rate was 78.5%: 32% complete remission, 25% nodular partial remission, 21.5%, partial remission. Median duration of response was 19 months and median survival was 42 months. Sixteen patients (57%) developed neutropenia to < 0.5 x 10(9)/l and 12 (43%) infectious complications. Four patients developed large cell lymphoma (Richter's syndrome) and 2 acute myeloid leukemia. FCM is a useful combination for relapsed or refractory CLL and low grade NHL with high response rates and long duration of response. The role of FCM as first line therapy deserves study as well as its combination with the monoclonal antibody Rituximab.     

Treatment of advanced refractory lymphomas with a combination of carmustine, bleomycin, teniposide, dexamethasone, and cisplatin (the BBVDD regimen). An ECOG pilot study.

Forty-four patients with relapsed, refractory malignant lymphomas (12 Hodgkin's disease, 32 non-Hodgkin's lymphoma) were treated with a combination of carmustine, bleomycin, teniposide, dexamethasone, and cisplatin (BBVDD regimen). Patients had failed at least one, and frequently two, chemotherapy regimens before admission to the study. Of the patients with Hodgkin's disease, 2 (17%) achieved complete response (CR), and 3 (25%) attained a partial response (PR) for an overall response rate (CR + PR) of 42%. Among the patients with non-Hodgkin's lymphoma there were 6 CR (19%) and 12 PR (37%), for an overall response rate of 56%. Median durations of response ranged from 2.5 months for nodular non-Hodgkin's lymphoma in PR to 28.5 + months for Hodgkin's disease in CR. In these heavily pretreated patients, the incidence of toxic effects was grade 3 (48%), grade 4 (23%), grade 5 (2%). The one death (grade 5 toxicity) was attributed to pulmonary impairment due to bleomycin. BBVDD is a moderately effective regimen for the palliation of patients with refractory lymphomas and merits further study.     

The role of mitoxantrone in non-Hodgkin's lymphoma

The development of doxorubicin was an important advance in the treatment of patients with non-Hodgkin's lymphoma (NHL). Alternatives to doxorubicin, such as mitoxantrone (Novantrone), have less nonhematologic toxicity and could offer a therapeutic advantage in some situations if similar antilymphoma activity exists. Several combination regimens that include mitoxantrone have been shown to be active. These include mitoxantrone/ifosfamide (Ifex) and mitoxantrone/etoposide combinations as salvage therapy for aggressive lymphomas. Mitoxantrone in combination with fludarabine (Fludara) for the treatment of newly diagnosed follicular lymphomas and in combination with fludarabine and dexamethasone for relapsed/refractory follicular lymphomas has produced high complete response rates. Other evolving uses of mitoxantrone include combination therapy with cladribine (Leustatin) or rituximab (Rituxan), and as part of conditioning regimens for hematopoietic stem cell transplantation. In diffuse aggressive lymphoma, mitoxantrone, 10 mg/m2, substituted for doxorubicin, 50 mg/m2, results in a poorer response when CNOP (cyclophosphamide [Cytoxan, Neosar], mitoxantrone [Novantrone], vincristine [Oncovin], prednisone) is compared to CHOP (cyclophosphamide, doxorubicin HCl vincristine, prednsione); however, increasing the mitoxantrone dose to 12 mg/m2 in either the CNOP or CMP-BOP (cyclophosphamide, mitoxantrone, procarbazine [Matulane], bleomycin [Blenoxane], vincristine, prednisone) regimens yields results comparable to those achieved with the doxorubicin-containing regimen. Comparable results have also been observed when 10 mg/M2 of mitoxantrone was substituted for 45 mg/M2 of doxorubicin in the m-BACOD (methorexate, bleomycin, doxorubicin [Adriamycin], cyclophosphamide, vincristine, dexamethasone) regimen. Mitoxantrone is active in NHL, and combinations including mitoxantrone can be used effectively and may provide an advantage in the elderly.     

The role of mitoxantrone in the treatment of indolent lymphomas

With the introduction of newer therapeutic approaches, survival in indolent non-Hodgkin's lymphoma (NHL) appears to be improving. Mitoxantrone (Novantrone; Serono, Inc.; Rockland, MA, http://www.seronousa.com), an anthracenedione with low cardiotoxic potential, has demonstrated activity in indolent NHL in combination with fludarabine (Fludara; Berlex Laboratories; Wayne, NJ, http://www.berlex.com) and other agents. In a Southwest Oncology Group trial (SWOG 9501), treatment with fludarabine and mitoxantrone (FM) induced a complete remission (CR) rate of 44% and a partial remission (PR) rate of 50% in untreated patients. The estimated 4-year progression-free survival (PFS) rate was 38%. In a multicenter Italian trial comparing the efficacy of FM with that of cyclophosphamide, doxorubicin (Adriamycin; Bedford Laboratories; Bedford, OH, http://www.bedfordlabs.com), vincristine (Oncovin; Eli Lilly and Company; Indianapolis, IN, http://www.lilly.com), and prednisone (Deltasone; Pfizer Pharmaceuticals; New York, NY, http://www.pfizer.com), CHOP, followed by rituximab (Rituxan; Genentech, Inc.; South San Francisco, CA, http://www.gene.com) for patients with incomplete clinical or molecular responses, the CR and molecular response rates were significantly higher in the FM arm, but the PFS and overall survival (OS) rates did not differ between the two arms. However, FM was also significantly less toxic than CHOP. The administration of rituximab following chemotherapy resulted in higher clinical and molecular response rates in both arms. In a separate trial, FM plus dexamethasone (Decadron; Merck and Co., Inc.; Whitehouse Station, NJ, http://www.merck.com), FND, plus concurrent rituximab produced a CR rate of 92%. In a randomized German study, patients with indolent lymphomas received FM plus cyclophosphamide (FCM) or FCM with rituximab. PFS and OS times were significantly better for patients who received combined chemoimmunotherapy. Mitoxantrone-based regimens are highly active and well tolerated in patients with both relapsed and previously untreated indolent lymphomas. The addition of rituximab appears to increase the activity of the FM, FND, and FCM regimens. Although the results of the Italian multicenter study support the superiority of FM over CHOP in terms of clinical and molecular responses and tolerability, additional studies using rituximab in combination with both of these regimens should be attempted to determine the possible further benefit of both in the management of indolent lymphoma. Because cure remains elusive in patients with indolent lymphoma, maximum prolongation of PFS with minimal toxicity and maximum preservation of quality of life should remain central goals of treatment.     

Comparison on therapeutic effects of RFT and RCTVP regimen in the treatment of patients with indolent B-cell lymphoma in China

To compare the efficacy and safety of RFT (retuximab, fludarabine, pirarubicin) with RCTVP (retuximab, cyclophophamide, pirarubicin, vindesine and prednisone) in 248 indolent B-cell non-Hodgkin's lymphoma (NHL) patients. Two hundred and forty-eight patients with indolent B-cell NHL were treated with combined chemotherapy, including RFT and RCTVP, from January 2002 to December 2010 in Tianjin Cancer Hospital. The rate of response, toxicity and long-term survival for the two regimens were analyzed retrospectively. For the previously untreated patients, overall response rate for RFT arm and RCTVP arm was 71.7 and 70.6%, and complete response rate was 47.5 and 54.9%, respectively (P?>?0.05). For the refractory and relapsed patients, overall response (OR) rate and complete response (CR) rate were significantly improved in the RFT arm versus the RCTVP arm (P?相似文献   

High dose sequential chemotherapy and autologous stem cell transplantation in patients with relapsed/refractory lymphoma

Although high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) has become the standard approach for patients with relapsed/refractory Hodgkin's disease (HD) or non-Hodgkin's lymphoma (NHL), more than 50% of patients will experience relapse following ASCT. High-dose sequential chemotherapy (HDSC) can intensify the conventional salvage treatment and improve the outcome of ASCT by maximal debulking of the tumor load with the use of non-cross resistant drugs, each at their maximal tolerated doses. We conducted a phase II study in 40 patients with relapsed/refractory HD (n = 18) and NHL (n = 22) using HDSC followed by ASCT. Only patients sensitive to salvage chemotherapy were eligible for the protocol, consisting of three phases. Phase I consisted of cyclophosphamide (4.5 g/m²) followed by G-CSF and peripheral blood stem cell (PBSC) collection. Phase II consisted of etoposide (2 g/m²). The transplant phase consisted of mitoxantrone (60 mg/m²) and melphalan (180 mg/m²) followed by PBSC infusion. Eleven out of nineteen patients with B-cell lymphoma received rituximab. Prior to HDSC, 45% of the patients were in complete remission (CR) and 55% were in partial remission (PR). After completion of all phases of the protocol, 35 out of 39 evaluable patients achieved CR (90%) and this was durable in 30 (75%) patients with a projected progression-free survival (PFS) rate at 4 years of 71.7%. Treatment-related mortality rate at day +100 was 2.5% (n = 1). At a median follow-up of 32 months (range, 3 - 61), nine patients relapsed/progressed and eleven patients died. The estimated 4-year PFS and overall survival (OS) were 72.2% and 47.6% in HD patients and 70.3% and 69.4% in NHL patients, respectively. Factors predicting OS were response to conventional salvage therapy and stage prior to salvage therapy. When compared to patients achieving PR, patients who attained CR prior to HDSC had a significantly higher probability of 4-year OS (78.4% vs 31.3%, p = 0.02). Three prognostic subgroups were defined according to the score determined by stage prior to initiation of salvage chemotherapy, remission duration prior to salvage (refractory/early relapse vs. late relapse) and response to salvage. Prognostic score was found to predict OS, PFS and event free survival (EFS). In conclusion, HDSC followed by ASCT is an effective salvage therapy with acceptable toxicity, allowing further consolidation of response attained by conventional salvage therapy.     

Mitoxantrone-DHAP with GM-CSF: an active but myelosuppressive salvage therapy for relapsed/refractory aggressive non-Hodgkin's lymphoma

This study was designed to evaluate the efficacy and toxicity of dose intensifying DHAP (dexamethasone, cytarabine and cisplatin) salvage chemotherapy by adding mitoxantrone with GM-GSF support in patients with relapsed or refractory non-Hodgkin's lymphoma (NHL). From March 1992 to January 1995, 22 patients with intermediate and high grade (aggressive) NHL refractory or relapsed after adriamycin containing chemotherapy regimens were treated with M-DHAP+GM-CSF, (dexamethasone 40 mg i.v. days 1-4, cisplatin 100 mg/m2 i.v. by continuous infusion over 24 hours on day 1, cytarabine 2 gm/m2, i.v. every 12 hours for 2 doses on day 2, mitoxantrone 10 mg/m2 i.v. on days 3 and 4 and GM-CSF 250-500 microg/m2 s.c. daily beginning day 5 until absolute neutrophil count recovery. Most patients had poor prognostic factors including primary refractory disease (18/22), bulky disease (12/22), elevated LDH (9/22), or bone marrow involvement (8/22). All 22 patients were evaluable. The overall response rate was 41% (CR 23% and PR 18%). There were three toxic deaths, all related to sepsis. Median progression free survival (PFS) and overall survival (OS) rates were 5.2 months and 11.8 months respectively. At the same time of the analysis two patients were alive after high-dose therapy and bone marrow transplant at 34 and 36 months follow-up and two were alive with disease. The maximal acceptable dosage of mitoxantrone was 10 mg/m2 x 2 due to serious hematologic toxicity. Treatment delays and dose reductions compromised delivering the optimal dose intensity of M-DHAP. A poor prognostic group of patients with refractory or recurrent aggressive lymphoma, many of whom were not eligible for high-dose therapy and stem cell transplantation were treated with repeated cycles of dose intensified DHAP with growth factor support. Although M-DHAP had therapeutic activity even in patients considered to have primary refractory disease, myelosuppression was dose limiting and frequently limited the number of cycles. Therefore, if M-DHAP is to be further evaluated, therapeutic results may be improved further by incorporating strategies to reduce myelotoxicity such as the use of growth factors to reduce platelet transfusion requirements or the use of autologous stem cell support after each cycle.
