Comparison of ICE (ifosfamide-carboplatin-etoposide) versus DHAP (cytosine arabinoside-cisplatin-dexamethasone) as salvage chemotherapy in patients with relapsed or refractory lymphoma

Background: High dose chemotherapy with autologous stem cell transplantation is currently the treatment of choice for relapsed or refractory lymphoma patients. However, its applicability is mostly restricted to patients responding to salvage chemotherapy. Optimal salvage regimen for these patients is unclear. In this study, our aim was to compare the efficacy and toxicity profiles of DHAP (cytosine arabinoside, cisplatin and dexamethasone) and ICE (ifosfamide, carboplatin and etoposide) regimens in the salvage treatment of relapsed and refractory lymphoma. Patients and Methods: In this retrospective analysis, 53 patients with primary refractory or relapsed Hodgkin's disease (HD) (n = 13) or non-Hodgkin lymphoma (NHL) (n = 40) who received ICE or DHAP salvage regimen were included. Results: Of 53 patients, 21 (39,6%) were female and the median age was 43 years. A total of 73 courses of ICE and 59 courses of DHAP were administered. Response could be evaluated in 49 patients (36 NHL and 13 HD). Of 49 patients, 11 (22.5%) achieved complete remission (CR) and 17 (35%) achieved partial remission (PR), leading to an overall response rate (ORR: CR + PR) of 57.5%. In the evaluable ICE group (n = 22) rates of CR, PR, and ORR were 27%, 41% and 68% and in the DHAP group (n = 27) rates of CR, PR, and ORR were 18%, 30% and 48% (p = 0.24, for ORR). Toxicity with both regimens was within acceptable limits. The major grade III-IV toxicities for both groups were hematological (neutopenia and thrombocytopenia). The main non-hematological toxicity was renal and observed in 8 patients. Conclusion: Although the toxicity profiles of both ICE and DHAP regimens were similar in the treatment of patients with relapsed or refractory HD or NHL, ICE seems to have higher rates of response than DHAP regimen does.

Time-intensified dexamethasone/cisplatin/cytarabine: an effective salvage therapy with low toxicity in patients with relapsed and refractory Hodgkin's disease.

BACKGROUND: An important variable affecting outcome in relapsed and refractory Hodgkin's disease (HD) is the potential of conventional salvage chemotherapy to reduce tumor volume before high-dose chemotherapy (HDCT) and autologous stem cell transplantation. Currently, the optimal salvage chemotherapy regimen for these patients is unclear. Since dexamethasone/cisplatin/cytarabine (DHAP) given at 3-4 week intervals has been shown to be very effective in patients with relapsed aggressive non-Hodgkin's lymphoma, we evaluated this regimen given at a median of 16-day intervals in patients with relapsed and refractory HD. PATIENTS AND METHODS: Patients with relapsed or refractory HD were treated with two cycles of DHAP [dexamethasone 40 mg intravenously (i.v.) day 1-4, cisplatin 100 mg/m(2) i.v. as 24-h continuous infusion day 1, and cytarabine 2 g/m(2) i.v. 12q day 2]. Granulocyte colony-stimulating factor (G-CSF) was given at a dose of 5 micro g/kg from day 4 until day 13. Patients with partial remission (PR) or complete remission (CR) after two cycles of DHAP received sequential HDCT. RESULTS: The median age of the 102 patients included was 34 years (range 21-64 years). Forty-two percent of the patients had late relapse, 29% early relapse, 12% multiple relapse and 16% primary progressive/refractory disease. The response rate (RR) after two cycles of DHAP was 89% (21% CR, 68% PR). The RRs for patients with late, early, multiple and progressive HD were 91%, 93%, 92% and 65%, respectively. Using the chi-square test for independence, remission status (relapsed HD versus progressive HD) and stage at relapse (stage I/II versus stage III/IV) were significant factors for response to DHAP. WHO grade 4 leukocytopenia and thrombocytopenia were the main toxic- ities occurring in 43% (mean duration 1.1 days, range 0-6) and 48% (mean duration 1.4 days, range 0-11) of all courses, respectively. Neither severe infections nor treatment-related deaths occurred. Peripheral blood stem cells (PBSCs) were collected after the first cycle DHAP in eight patients. The hematopoietic progenitors showed a very rapid increase from day 10 with a synchronous and impressive peak on day 12. A mean of 6.1 x 10(6)/kg CD34(+) cells were collected per apheresis. As originally recommended in the protocol, PBSCs were routinely collected during sequential HDCT in the remaining patients. CONCLUSIONS: A brief tumor-reducing program with two cycles of DHAP given in short intervals supported by G-CSF is effective and well-tolerated in patients with relapsed and refractory HD. This regimen can be used to mobilize stem cells and select those patients with chemosensitive relapse who should subsequently be treated with HDCT.     

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.     

Rituximab, gemcitabine, cisplatin, and dexamethasone in patients with refractory or relapsed aggressive B-cell lymphoma

This study was conducted to evaluate the efficacy and safety of Rituximab, Gemcitabine, Cisplatin, and Dexamethasone (R-GDP) in relapsed or refractory aggressive B-Cell Non-Hodgkin's Lymphoma (NHL). Treatments consisted of rituximab 375?mg/m(2), i.v. on day 1; gemcitabine 1,000?mg/m(2), i.v. on days 1 and 8, dexamethasone 40?mg i.v. on days 1-4, and cisplatin 25?mg/m(2) i.v. on days 1-3, every 21?days. The primary end-points were the overall survival (OS) and progression-free survival (PFS). Secondary endpoints included response rate (ORR; CR) and toxicities. Eligible patients could then proceed to high-dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT) or receive up to six treatment cycles. From January 2005 to December 2010, 50 successive patients at Tianjin cancer hospital lymphoma department were enrolled in this study. All patients were recurrent or refractory aggressive B-cell NHL, including diffuse large B-cell lymphoma (n?=?30) and follicular lymphoma grade 3b (n?=?20). The median follow-up time was 42?months (range, 12-70). After two cycles, the overall response rate was 72.0?%, with a CR/CRu rate of 56?%. The 2-year OS and PFS of all patients were 70.0 and 48.0?%, respectively. Grade III-IV neutropenia and thrombocytopenia occurred in 34 and 40?% of patients, respectively. Twenty-one patients (42?%) proceeded to ASCT. Higher International Prognostic Index and refractory disease were independently associated with worse survival and progression-free survival. R-GDP chemotherapy in patients with refractory or relapsed aggressive B-Cell NHL was effective as a salvage therapy and helpful for HDC/ASCT.

High-dose sequential chemotherapy followed by autologous stem cell transplantation in relapsed and refractory aggressive non-Hodgkin's lymphoma: results of a multicenter phase II study.

BACKGROUND: Combination chemotherapy can cure patients with non-Hodgkin's lymphoma (NHL), but those who suffer treatment failure or relapse still have a poor prognosis. High-dose chemotherapy (HDCT) with autologous stem cell transplantation (ASCT) can improve the outcome of these patients. We evaluated an intensified high-dose sequential chemotherapy program with a final myeloablative course. PATIENTS AND METHODS: Inclusion criteria were age 18-65 years, histologically proven primary progressive or relapsed aggressive NHL and eligibility for HDCT. The therapy consists of two cycles DHAP: dexamethasone 40 mg (day 1-4), high-dose cytarabine 2 g/m2 12q (day 2), cisplatin 100 mg/m2 (day 51); patients with partial (PR) or complete remission (CR) received cyclophosphamide 4 g/m2 (day 37), followed by peripheral blood stem cell (PBSC) harvest; methotrexate 8 g/m2 (day 1) plus vincristine 1.4 mg/m2 (day 51); and etoposide 500 mg/m2 (day 58-62). The final myeloblative course was BEAM: cytarabine 200 mg/m2 12q (day 81-84), etoposide 150 mg/m2 12q (day 81-84), melphalan 140 mg/m2 (day 80), carmustin 300 mg/m2 (day 80) followed by PBSCT. RESULTS: Fifty-seven patients (median age 43 years, range 24-65) were enrolled: 23 (40%) patients were refractory to primary therapy and 34 (60%) patients had relapsed NHL. The response rate (RR) after 2 cycles of DHAP was 72% (9% CR, 63% PR) and at the final evaluation (100 days post transplantation) 43% (32% CR, 11% PR). Toxicity was tolerable. Median follow-up was 25 months (range 1-76 months). Freedom from second failure (FF2F) and overall survival (OS) at 2 years were 25% and 47% for all patients, respectively. FF2F at 2 years for patients with relapse and for patients refractory to primary therapy were 35% and 9% (P=0.0006), respectively. OS at 2 years for patients with relapse and for patients refractory to primary therapy were 58% and 24% (P=0.0044), respectively. CONCLUSIONS: We conclude that this regimen is feasible, tolerable and effective in patients with relapsed NHL. In contrast, the results in patients with progressive disease are unsatisfactory.

目的 观察和评价DHAP（顺铂、阿糖胞苷、地塞米松）和GDP（吉西他滨、顺铂、地塞米松）方案治疗复发、难治性非霍奇金淋巴瘤（Non—Hodgkin lymphoma，NHL）的疗效及毒副反应。方法45例复发、难治性NHL患者随机分成两组：DHAP方案组21例，采用顺铂、阿糖胞苷、地塞米松联合化疗；GDP方案组24例，采用吉西他滨、顺铂、地塞米松联合化疗，化疗2周期后评价疗效和毒副反应。结果全部患者均可评价疗效和毒副反应。DHAP组；完全缓解（CR）5例（23．8％），部分缓解（PR）9例（42．9％），稳定（SD）5例（23．8％），进展或恶化（PD）2例（9．5％），总缓解率（CR＋PR）66．7％；GDP组：CR4例（16．7％），PR10例（41．7％），SD7例（29．2％），PD3例（12．5％），总缓解率（CR＋PR）58．3％，总缓解率两组比较差异无统计学意义（P〉0．05）。主要毒副反应为消化道反应和骨髓抑制，患者均可耐受。消化道反应和白细胞减少两组比较差异无统计学意义（P〉0．05）；血小板减少DHAP组明显高于GDP组（P〈0．05）。结论DHAP和GDP方案治疗复发、难治性NHL的总缓解率相似，毒副反应均可耐受，DHAP方案血小板减少比GDP方案更明显。
