Melphalan and prednisone plus thalidomide versus melphalan and prednisone alone or reduced-intensity autologous stem cell transplantation in elderly patients with multiple myeloma (IFM 99–06): a randomised trial

BACKGROUND In multiple myeloma, combination chemotherapy with melphalan plus prednisone is still regarded as the standard of care in elderly patients. We assessed whether the addition of thalidomide to this combination, or reduced-intensity stem cell transplantation, would improve survival. METHODS Between May 22, 2000, and Aug 8, 2005, 447 previously untreated patients with multiple myeloma, who were aged between 65 and 75 years, were randomly assigned to receive either melphalan and prednisone (MP; n=196), melphalan and prednisone plus thalidomide (MPT; n=125), or reduced-intensity stem cell transplantation using melphalan 100 mg/m2 (MEL100; n=126). The primary endpoint was overall survival. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00367185. FINDINGS After a median follow-up of 51.5 months (IQR 34.4-63.2), median overall survival times were 33.2 months (13.8-54.8) for MP, 51.6 months (26.6-not reached) for MPT, and 38.3 months (13.0-61.6) for MEL100. The MPT regimen was associated with a significantly better overall survival than was the MP regimen (hazard ratio 0.59, 95% CI 0.46-0.81, p=0.0006) or MEL100 regimen (0.69, 0.49-0.96, p=0.027). No difference was seen for MEL100 versus MP (0.86, 0.65-1.15, p=0.32). INTERPRETATION The results of our trial provide strong evidence to indicate that the use of thalidomide in combination with melphalan and prednisone should, at present, be the reference treatment for previously untreated elderly patients with multiple myeloma.

Candidemia in Cancer Patients: A Prospective, Multicenter Surveillance Study by the Invasive Fungal Infection Group (IFIG) of the European Organization for Research and Treatment of Cancer (EORTC)

In a surveillance study of candidemia in cancer patients that was conducted by the European Organization for Research and Treatment of Cancer, 249 episodes were noted; Candida albicans was isolated in 70% (63) of the 90 cases involving patients with solid tumors (tumor patients) and in 36% (58) of the 159 involving those with hematologic disease (hematology patients). Neutropenia in tumor patients and acute leukemia and antifungal prophylaxis in hematology patients were significantly associated with non-albicans candidemia in a multivariate analysis. Overall 30-day mortality was 39% (97 of 249). In a univariate analysis, Candida glabrata was associated with the highest mortality rate (odds ratio, 2.66). Two multivariate analyses showed that mortality was associated with older age and severity of the underlying disease. Among hematology patients, additional factors associated with mortality were allogeneic bone marrow transplantation, septic shock, and lack of antifungal prophylaxis.

Efficacy of Melphalan and Prednisone Plus Thalidomide in Patients Older Than 75 Years With Newly Diagnosed Multiple Myeloma: IFM 01/01 Trial

PURPOSE Until recently, melphalan and prednisone were the standards of care in elderly patients with multiple myeloma. The addition of thalidomide to this combination demonstrated a survival benefit for patients age 65 to 75 years. This randomized, placebo-controlled, phase III trial investigated the efficacy of melphalan and prednisone plus thalidomide in patients older than 75 years with newly diagnosed myeloma. PATIENTS AND METHODS Between April 2002 and December 2006, 232 previously untreated patients with myeloma, age 75 years or older, were enrolled and 229 were randomly assigned to treatment. All patients received melphalan (0.2 mg/kg/d) plus prednisone (2 mg/kg/d) for 12 courses (day 1 to 4) every 6 weeks. Patients were randomly assigned to receive 100 mg/d of oral thalidomide (n = 113) or placebo (n = 116), continuously for 72 weeks. The primary end point was overall survival. RESULTS After a median follow-up of 47.5 months, overall survival was significantly longer in patients who received melphalan and prednisone plus thalidomide compared with those who received melphalan and prednisone plus placebo (median, 44.0 v 29.1 months; P = .028). Progression-free survival was significantly prolonged in the melphalan and prednisone plus thalidomide group (median, 24.1 v 18.5 months; P = .001). Two adverse events were significantly increased in the melphalan and prednisone plus thalidomide group: grade 2 to 4 peripheral neuropathy (20% v 5% in the melphalan and prednisone plus placebo group; P < .001) and grade 3 to 4 neutropenia (23% v 9%; P = .003). CONCLUSION This trial confirms the superiority of the combination melphalan and prednisone plus thalidomide over melphalan and prednisone alone for prolonging survival in very elderly patients with newly diagnosed myeloma. Toxicity was acceptable.

Rituximab combined with chemotherapy and interferon in follicular lymphoma patients: results of the GELA-GOELAMS FL2000 study

The FL2000 study was undertaken to evaluate the combination of the anti-CD20 monoclonal antibody rituximab with chemotherapy plus interferon in the first-line treatment of follicular lymphoma patients with a high tumor burden. Patients were randomly assigned to receive either 12 courses of the chemotherapy regimen CHVP (cyclophosphamide, adriamycin, etoposide, and prednisolone) plus interferon-alpha2a (CHVP+I arm) over 18 months or 6 courses of the same chemotherapy regimen combined with 6 infusions of 375 mg/m(2) rituximab and interferon for the same time period (R-CHVP+I arm). After a median follow-up of 5 years, event-free survival estimates were, respectively, 37% (95% confidence interval [CI], 29%-44%) and 53% (95% CI, 45%-60%) in the CHVP+I and R-CHVP+I arm (P = .001). Five-year overall survival estimates were not statistically different in the CHVP+I (79%; 95% CI, 72%-84%) and R-CHVP+I (84%; 95% CI, 78%-84%) arms. In a multivariate regression analysis, event-free survival was significantly influenced by both the Follicular Lymphoma International Prognostic Index score (hazard ratio = 2.08; 95% CI, 1.6%-2.8%) and the treatment arm (hazard ratio = 0.59; 95% CI, 0.44%-0.78%). With a 5-year follow-up, the combination of rituximab with CHVP+I provides superior disease control in follicular lymphoma patients despite a shorter duration of chemotherapy. This studys clinical trial was registered at the National Institutes of Health website as no. NCT00136552.

An EORTC International Multicenter Randomized Trial (EORTC Number 19923) Comparing Two Dosages of Liposomal Amphotericin B for Treatment of Invasive Aspergillosis

This is the first completed prospective randomized clinical efficacy trial of antifungals in the treatment of invasive aspergillosis (IA) and the first to compare the clinical efficacy of two dosages of liposomal amphotericin B (L-AmB) for IA in neutropenic patients with cancer or those undergoing bone marrow transplantation. Eighty-seven of 120 patients were eligible and evaluable. Clinical responses were documented for 26 (64%) of 41 patients receiving 1 mg/(kg.d) (L-AmB-1) and 22 (48%) of 46 receiving 4 mg/(kg.d) (L-AmB-4). Radiologic response rates were similar: 24 (58%) of the L-AmB-1 recipients and 24(52%) of the L-AmB-4 recipients. The six-month survival rates were 43% (L-AmB-1) and 37% (L-AmB-4). These differences were not significant. The numbers of deaths directly due to IA at 6 months were similar: 9 (22%) of 41 L-AmB-1 recipients and 9 (20%) of 46 L-AmB-4 recipients. No other variable independently influenced survival, apart from central nervous system IA. L-AmB is effective in treating approximately 50%-60% of patients who have IA. A 1-mg/(kg.d) dosage is as effective as a 4-mg/(kg.d) dosage, and no advantages to use of the higher, more expensive, dosage has been observed.

Bortezomib plus dexamethasone versus reduced-dose bortezomib, thalidomide plus dexamethasone as induction treatment before autologous stem cell transplantation in newly diagnosed multiple myeloma.

The Intergroupe Francophone du Myelome conducted a randomized trial to compare bortezomib-dexamethasone (VD) as induction before high-dose therapy (HDT) and autologous stem cell transplantation (ASCT) to a combination consisting of reduced doses of bortezomib and thalidomide plus dexamethasone (vtD) in patients with multiple myeloma. Overall, a total of 199 patients were centrally randomly assigned to receive VD or vtD. After 4 cycles, the complete response (CR) rate was the same in both groups (13% in the vtD arm, 12% in the VD arm, P = .74). However, the CR plus very good partial response (VGPR) rate was significantly higher in the vtD arm (49% vs 36%, P = .05). After ASCT, the CR plus VGPR rate was significantly higher in the vtD arm (74% vs 58%, P = .02). The reduced doses of bortezomib and thalidomide translated into a reduced incidence of peripheral neuropathy (PN): grade ≥ 2 PN were reported in 34% in the VD arm versus 14% in the vtD arm (P = .001). vtD, including reduced doses of bortezomib and thalidomide, yields higher VGPR rates compared with VD and can be considered a new effective triplet combination before HDT/ASCT.

Doxorubicin-containing regimen with or without interferon alfa-2b for advanced follicular lymphomas: final analysis of survival and toxicity in the Groupe d'Etude des Lymphomes Folliculaires 86 Trial.

PURPOSE To compare progression-free survival (PFS), overall survival (OS), and toxicity of a doxorubicin-containing regimen administered alone or in combination with interferon alfa-2b (IFNalpha) in patients with low-grade follicular lymphoma (FL) and poor prognostic factors. PATIENTS AND METHODS Two hundred sixty-eight patients with advanced-stage FL received cyclophosphamide, doxorubicin, teniposide, and prednisone (CHVP) monthly for 6 months, then every 2 months for 12 months. After randomization, 242 patients were evaluated for efficacy: 119 received CHVP alone, and 123 also received IFNalpha at a dose of 5 million units three times weekly for 18 months. RESULTS After a 6-year median follow-up, the patients treated with CHVP + IFNalpha showed significantly longer median PFS than those who received CHVP alone (2.9 years v 1.5 years, respectively; P = .0002) and significantly longer median OS (not reached v 5.6 years, respectively; P = .008). Although some side effects, which included neutropenia, asthenia, fever, elevated serum transaminase levels, flu-like symptoms, and thrombocytopenia, were more frequently observed in patients who received the combination regimen, these reactions were moderate. IFNalpha was withdrawn because of toxicity in 10% of the patients, and a dosage reduction or temporary suspension was required in 28%. CONCLUSION With long-term follow-up of 6 years, these results confirm that the addition of IFNalpha to a doxorubicin-containing regimen for patients with advanced-stage and clinically aggressive FL not only increased PFS, as in most other similar trials, but also prolonged OS. Toxicity was moderate. The beneficial effects of this combined chemotherapy and IFNalpha regimen on OS probably reflect the selection of FL patients with poor prognostic factors.

Early detection of doxorubicin cardiotoxicity: Interest of Doppler echocardiographic analysis of left ventricular filling dynamics

Doxorubicin (Adriamycin) is an effective anticancer agent but its therapeutic value is limited by its myocardial cardiotoxicity. To improve early detection of doxorubicin cardiotoxicity, studies were performed in patients with long-term doxorubicin treatment using pulsed Doppler echocardiography to assess the changes in left ventricular (LV) diastolic filling dynamics. M-mode echocardiographic systolic parameters and Doppler transmitral flow velocities were analyzed in two groups of patients. In group A (45 patients, mean age 45 +/- 13 years), the results were compared with those of a control group of 35 normal subjects matched for age. In group B (19 patients, mean age 44 +/- 12 years), the pretreatment results were prospectively compared with those obtained during treatment protocol. The patients received a cumulative dosage of 253 +/- 125 mg/m2 of doxorubicin for group A and 240 +/- 135 mg/m2 for group B. After doxorubicin treatment, in the two groups there were no significant changes in LV dimensions, shortening fraction, and mean velocity of circumferential fiber shortening (VCF). In contrast, Doppler echocardiographic parameters of diastolic function were significantly modified after doxorubicin in the two groups:isovolumic relaxation period was prolonged by 32% in group A (p less than 0.001) and by 22% in group B (p less than 0.005).2+ The early peak flow velocity was reduced by 18% in group A (p less 0.002) and by 13% in group B (p less than 0.04), and the ratio early peak flow velocity/atrial peak flow velocity also decreased significantly, by 23% in group A (p less than 0.001) and by 20% in group B (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

Late intensification chemotherapy with autologous bone marrow transplantation in selected small-cell carcinoma of the lung: a randomized study.

A multicentric randomized prospective trial was conducted to test whether late intensification chemotherapy would increase the remission rate, the relapse-free survival, and the survival of small-cell lung cancer patients responding to induction chemotherapy. Autologous bone marrow transplantation was used as support to reduce the duration of the aplasia induced by very high-dose chemotherapy. As induction chemotherapy, 101 patients received, during a period of 5 months, a total dosage of 120 mg/m2 methotrexate, 4.5 mg/m2 vincristine, 1,800 mg/m2 cyclophosphamide, 180 mg/m2 doxorubicin, 160 mg/m2 cisplatin, 750 mg/m2 VP-16-213, and 30 Gy prophylactic cranial irradiation. Forty-five patients, selected for their sensitivity to this induction treatment, were randomized to a last cycle of chemotherapy that combined cyclophosphamide, BCNU, and VP-16-213 either at a conventional dosage of 750 mg/m2 intravenously (IV), 60 mg/m2 IV, and 600 mg/m2 orally or alternatively at a very high dosage of 6 g/m2 IV, 300 mg/m2 IV, and 500 mg/m2 IV, respectively. In the late intensification group, the complete remission rate increased from 39% before randomization to 79% after high-dose chemotherapy. Median relapse-free survivals after randomization for intensified and control chemotherapy groups were 28 and 10 weeks, respectively (P = .002). Median overall survival after induction therapy was 68 weeks for the intensified group compared with 55 weeks for the conventional therapy group (P = .13). Four patients died during intensification. Patients in both groups relapsed at the primary site. It can thus be concluded that late intensification chemotherapy for sensitive small-cell lung cancer increases the complete remission rate and resulted in a statistically significant increase in the relapse-free survival. However, since relapse occurred at the primary site and toxicity was high, overall survival was not significantly improved.

Superiority of the Triple Combination of Bortezomib-Thalidomide-Dexamethasone Over the Dual Combination of Thalidomide-Dexamethasone in Patients With Multiple Myeloma Progressing or Relapsing After Autologous Transplantation: The MMVAR/IFM 2005-04 Randomized Phase III Trial From the Chronic Leukemia Working Party of the European Group for Blood and Marrow Transplantation

PURPOSE This prospective multicenter phase III study compared the efficacy and safety of a triple combination (bortezomib-thalidomide-dexamethasone [VTD]) versus a dual combination (thalidomide-dexamethasone [TD]) in patients with multiple myeloma (MM) progressing or relapsing after autologous stem-cell transplantation (ASCT). PATIENTS AND METHODS Overall, 269 patients were randomly assigned to receive bortezomib (1.3 mg/m(2) intravenous bolus) or no bortezomib for 1 year, in combination with thalidomide (200 mg per day orally) and dexamethasone (40 mg orally once a day on 4 days once every 3 weeks). Bortezomib was administered on days 1, 4, 8, and 11 with a 10-day rest period (day 12 to day 21) for eight cycles (6 months), and then on days 1, 8, 15, and 22 with a 20-day rest period (day 23 to day 42) for four cycles (6 months). RESULTS Median time to progression (primary end point) was significantly longer with VTD than TD (19.5 v13.8 months; hazard ratio, 0.59; 95% CI, 0.44 to 0.80; P = .001), the complete response plus near-complete response rate was higher (45% v 21%; P 0.001), and the median duration of response was longer (17.9 v 13.4 months; P.04) [corrected].The 24-month survival rate was in favor of VTD (71% v 65%; P = .093). Grade 3 peripheral neuropathy was more frequent with VTD (29% v 12%; P = .001) as were the rates of grades 3 and 4 infection and thrombocytopenia. CONCLUSION VTD was more effective than TD in the treatment of patients with MM with progressive or relapsing disease post-ASCT but was associated with a higher incidence of grade 3 neurotoxicity.
