Ifosamide, epirubicin and granulocyte colony-stimulating factor: a regimen for successful mobilization of peripheral blood progenitor cells in patients with multiple myeloma.

In general, the mobilization of peripheral blood progenitor cells (PBPC) in multiple myeloma (MM) patients is poor and is achieved in most cases by combined cyclophosphamide and G-CSF. This study was performed to examine the efficacy of combined ifosfamide/epirubicine and G-CSF for PBPC mobilization and purging. Sixteen patients suffering from multiple myeloma in stage II/A and III/A according to Durie and Salmon underwent chemotherapy consisting of a total of three cycles of ifosfamide (3 g/m(2) on days 1 and 2 and epirubicine 80 mg/m(2) on day 1) and G-CSF (10 or 20 microg/kg body weight (BW) daily until harvesting). PBPC harvesting was performed after the first and third cycle of chemotherapy. The median number of PBPC after the first cycle of chemotherapy was 7.79 x 10(6) CD34+ cells/kg BW (ranging from 0.94-26.36 x 10(6)) and 6.38 x 10(6) CD34+ cells/kg BW (ranging from 0.79-29.31 x 10(6)) after the third cycle of chemotherapy. Clinical re-evaluation after three cycles of chemotherapy showed 13 (81 per cent) patients in partial remission (PR), two (12 per cent) in complete remission (CR) and one (6.25 per cent) in stable disease (SD). No major side-effects were observed, six patients developed hematological toxicity stage IV WHO for a median of 3.9 days but no serious infection episodes occurred. Combined ifosfamide/epirubicin and standard G-CSF is able to mobilize sufficient PBPC without serious side-effects for patients with MM and for purging procedures resulting in a high proportion of complete remissions after tandem high-dose melphalan chemotherapy.

Efficacy of vinorelbine, epirubicin and prednisone combination regimen in pretreated elderly patients with aggressive non-Hodgkin's lymphoma.

BACKGROUND AND OBJECTIVES: To assess the efficacy and toxic profile of the NAEPP protocol, a regimen including vinorelbine, epirubicin and prednisone, in a particularly troublesome subset of patients: pretreated elderly patients with aggressive non-Hodgkin's lymphoma (NHL). DESIGN AND METHODS: From November 1998 to January 2000, 20 pretreated patients who had all relapsed after first-line VNCOP-B chemotherapy were enrolled in a phase II trial and treated with the NAEPP regimen: vinorelbine (25 mg/m(2) i.v. on days 1 and 8), epirubicin (40 mg/m(2) i.v. on days 1 and 8), and prednisone (40 mg/m(2) on days 1 and 8) with granulocyte colony-stimulating factor administered at 5 mg/kg/day on days 2-5 and days 9-12. Chemotherapy was repeated every 4 weeks for a total of 6 cycles. RESULTS: Six (30%) patients achieved complete remission (CR) and 7 (35%) had partial responses (PR), giving an overall response rate of 65%. The response rate was not affected either by type of relapse presentation (nodal versus nodal plus extranodal), presence of bulky disease, or time of relapse. No major toxic effects were recorded. INTERPRETATION AND CONCLUSIONS: These preliminary data suggest that the NAEPP regimen is an effective combination with a low toxicity profile in elderly pretreated patients with aggressive NHL. Further trials using NAEPP as a consolidation phase following first-line treatment are needed to establish the advantage in terms of CR rate and relapse-free survival in these patients.

Lomustine and melphalan cannot be replaced by cyclophosphamide and etoposide without reducing efficacy in MOPPEBVCAD chemotherapy for advanced Hodgkin's disease.

BACKGROUND AND OBJECTIVES: To evaluate the feasibility, toxicity and preliminary results of a potentially less toxic variant of the MOPPEBVCAD chemotherapy regimen for advanced Hodgkin's disease: MOPPEBVCyED, in which cyclophosphamide and etoposide replace lomustine and melphalan, respectively, with the remaining components being unaltered. DESIGN AND METHODS: The study was multicenter, prospective and randomized, and enrolled 67 patients with newly diagnosed stage IIB, III, IV Hodgkin's disease (62 were expected on the grounds of statistical considerations). Radiotherapy was restricted to sites of bulky involvement or to areas that responded incompletely to chemotherapy. Median follow-up was 48 months. RESULTS: Comparing MOPPEBVCAD vs. MOPPEBVCyED, the results were as follows: complete remissions 35/35 vs. 30/32 (plus one partial remission and one disease progression); relapses 5 vs. 8; deaths 2 (one of myelodysplasia) vs. 2; delivered mean dose intensity (DI): lomustine 0.79+/-0.67 vs. cyclophosphamide 0.82+/-0.32; melphalan 0.80+/-0.13 vs. etoposide 0.86+/-0.18; average DI of the 7 drugs common to both regimens 0.73+/-0.10 vs. 0.83+/-0.11; all 9 drugs 0.75+/-0.13 vs. 0.84+/-0.09 (p=0.002); projected 5-year failure-free survival 0.79 vs 0.62; second cancers, two myelodysplasias vs. one carcinoma of the kidney. Toxicities were not statistically different except for heavier thrombocytopenia being recorded with MOPPEBVCAD. INTERPRETATION AND CONCLUSIONS: The higher cumulative and single drug DI recorded with MOPPEBVCyED may reflect better short-term tolerability, but it does not lead to better disease control. Its late toxicity may be expected to be lower in the future but at present it does not seem to be a sufficient reason to substitute MOPPEBVCyED for MOPPEBVCAD.

Chemotherapy with methotrexate, vinblastine, epirubicin and carboplatin (Carbo-MVE) in transitional cell urothelial cancer. A Hellenic Co-Operative Oncology Group study.

OBJECTIVES: We conducted a phase II study in order to assess the efficacy and toxicity of Carbo-MVE (carboplatin 250 mg/m2 i.v. day 1, methotrexate 25 mg/m2 i.v. days 1, 15 and 22, vinblastine 2.5 mg/m2 i.v. days 1, 15 and 22 and epirubicin 25 mg/m2 day 1). The regimen ws to be repeated every 28 days. METHODS: Forty-six patients with transitional cell carcinoma of the bladder entered the study. Patients with metastatic disease were treated for 6 cycles, while patients with locally advanced or locoregional disease had 4 cycles of induction chemotherapy followed by cystectomy or radiotherapy. RESULTS: Toxicity was generally mild and treatment well tolerated. The overall response rate was 54.4%, with 26% complete and 28.3% partial response rates. The median survival was 17.5 months with the complete responders to live significantly longer (64.82 months) than those who had a partial response (20.5 months), stable disease (15 months) or progressive disease (8.5 months). Survival was also significantly longer in patients with good performance status as well as in patients with locally advanced or locoregional disease. Finally, patients who had cystectomy as definitive treatment survived significantly longer (32 months) than those who had been irradiated (16 months). CONCLUSIONS: The Carbo-MVE regimen appears to be an effective and well-tolerated treatment in patients with transitional cell carcinoma of the bladder.
