Role of physical activity and sport in oncology: scientific commission of the National Federation Sport and Cancer CAMI.

This overview reports published data about the interaction between physical activity and sport during and after cancer on one hand and improvement in psychological parameters, survival and biological mechanisms underlying this effect on the other hand. Practising physical activity and sport during cancer modifies parameters assessing fatigue and quality of life and reduces symptoms of depression. An association also exists between the practise of physical activity and sport and overall and cancer-specific survivals, especially after breast cancer, colon cancer and prostate cancer. These benefits seem to be mediated by a modification of circulating levels of estrogens, insulin, IGF-1 and by a decrease in insulin-resistance, by alterations in the secretion of adipokines, and by a reduction in chronic inflammation through decreased levels of cytokines. There exist some obstacles to the practise of physical activity. These obstacles are mainly related to a fear of pain induced by physical activity and to overweight. These programmes of physical activity and sport cannot be offered to all patients since there are several contra-indications, with some being present since the initial visit and others appearing during cancer management either due to disease progression or related to iatrogenic effects. Whereas benefits from physical activity and sport among cancer patients seem obvious, there are still several pending clinical and biological issues.

Deletion of the 1p32 region is a major independent prognostic factor in young patients with myeloma: the IFM experience on 1195 patients.

Deletions of the 1p region appear as a pejorative prognostic factor in multiple myeloma patients (especially 1p22 and 1p32 deletions) but there is a lack of data on the real impact of 1p abnormalities on an important and homogeneous group of patients. To address this issue we studied by fluorescence in situ hybridization (FISH) the incidence and prognostic impact of 1p22 and 1p32 deletions in 1195 patients from the IFM (Institut Francophone du Myélome) cell collection. Chromosome 1p deletions were present in 23.3% of the patients (271): 15.1% (176) for 1p22 and 7.3% (85) for 1p32 regions. In univariate analyses, 1p22 and 1p32 appeared as negative prognostic factors for progression-free survival (PFS): 1p22: 19.8 months vs 33.6 months (P<0.001) and 1p32: 14.4 months vs 33.6 months (P<0.001); and overall survival (OS): 1p22: 44.2 months vs 96.8 months (P=0.002) and 1p32: 26.7 months vs 96.8 months (P<0.001). In multivariate analyses, 1p22 and 1p32 deletions still appear as independent negative prognostic factors for PFS and OS. In conclusion, our data show that 1p22 and 1p32 deletions are major negative prognostic factors for PFS and OS for patients with MM. We thus suggest that 1p32 deletion should be tested for all patients at diagnosis.

Treatment of older patients with mantle-cell lymphoma.

BACKGROUND: The long-term prognosis for older patients with mantle-cell lymphoma is poor. Chemoimmunotherapy results in low rates of complete remission, and most patients have a relapse. We investigated whether a fludarabine-containing induction regimen improved the complete-remission rate and whether maintenance therapy with rituximab prolonged remission. METHODS: We randomly assigned patients 60 years of age or older with mantle-cell lymphoma, stage II to IV, who were not eligible for high-dose therapy to six cycles of rituximab, fludarabine, and cyclophosphamide (R-FC) every 28 days or to eight cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) every 21 days. Patients who had a response underwent a second randomization to maintenance therapy with rituximab or interferon alfa, each given until progression. RESULTS: Of the 560 patients enrolled, 532 were included in the intention-to-treat analysis for response, and 485 in the primary analysis for response. The median age was 70 years. Although complete-remission rates were similar with R-FC and R-CHOP (40% and 34%, respectively; P=0.10), progressive disease was more frequent with R-FC (14%, vs. 5% with R-CHOP). Overall survival was significantly shorter with R-FC than with R-CHOP (4-year survival rate, 47% vs. 62%; P=0.005), and more patients in the R-FC group died during the first remission (10% vs. 4%). Hematologic toxic effects occurred more frequently in the R-FC group than in the R-CHOP group, but the frequency of grade 3 or 4 infections was balanced (17% and 14%, respectively). In 274 of the 316 patients who were randomly assigned to maintenance therapy, rituximab reduced the risk of progression or death by 45% (in remission after 4 years, 58%, vs. 29% with interferon alfa; hazard ratio for progression or death, 0.55; 95% confidence interval, 0.36 to 0.87; P=0.01). Among patients who had a response to R-CHOP, maintenance therapy with rituximab significantly improved overall survival (4-year survival rate, 87%, vs. 63% with interferon alfa; P=0.005). CONCLUSIONS: R-CHOP induction followed by maintenance therapy with rituximab is effective for older patients with mantle-cell lymphoma.

Widespread granuloma annulare and Hodgkin's disease.

The presence of coexistent disseminated granuloma annulare (GA) and Hodgkin's disease (HD) is rare, with only six reported patients to date. We describe a patient with HD who had limited GA 2 years before the diagnosis of HD; widespread GA appeared after first-line treatment and heralded disease relapse. GA lesions showed hypermetabolic images on positron emission tomography, an interesting finding of unknown significance. We suggest a new pathophysiological mechanism for this association, i.e. that the reactive T-lymphocyte population in HD may contribute to granuloma formation through the secretion of cytokines and the subsequent upregulation of certain metalloproteinases. Diffuse cutaneous GA should raise the possibility of underlying systemic lymphoma or HD.

Prospective randomized study comparing MEMID with a chop-like regimen in elderly patients with aggressive non-Hodgkin's lymphoma.

OBJECTIVE: This multicenter phase III study compared the MEMID regimen (mitoxantrone, VP16, methylglyoxal, ifosfamide and dexamethasone) with CEOP, a CHOP-like regimen (cyclophosphamide, epirubicin, vincristine and prednisone), in elderly patients (> or =65 years) with aggressive non-Hodgkin's lymphoma (NHL). METHODS: One hundred and forty-nine patients were eligible, 72 in the MEMID arm and 77 in the CEOP arm. The primary endpoint was to compare overall survival (OS) between groups, and secondary endpoints were event-free survival (EFS), response rate and toxicity. RESULTS: Neutropenia (p < 10(-5)), anemia (p < 10(-5)) and thrombocytopenia (p = 0.0006) were significantly more frequent in patients who received MEMID. We observed an objective response rate of 55.5% in the MEMID arm and 64.9% in the CEOP arm (p = 0.24). The median OS and EFS were 15.4 and 8.5 months in the MEMID arm, and 20.3 and 10.5 months in the CEOP arm (p = 0.59 and 0.47), respectively. The median EFS was 15.4 months in the MEMID arm and 20.3 months in the CEOP arm (p = 0.59). CONCLUSION: The increased toxicity without survival benefit confirms the superiority of CHOP and CHOP-like regimens for elderly patient with aggressive NHL.

Evaluation of buprenorphine maintenance treatment in a French cohort of HIV-infected injecting drug users.

BACKGROUND: Buprenorphine was approved in France for treating opiate dependence in July 1995 and can be prescribed by general practitioners (GPs). Most studies assessing buprenorphine maintenance treatment (BMT) outcomes have taken place in GP settings. An evaluation of BMT outcomes in patients already followed for their HIV-infection could supply additional information about the changes in addictive practices in a non-GP setting. METHODS: We assessed BMT discontinuations and the course of self-reported addictive behaviours and characteristics associated with buprenorphine-injection misuse in 114 HIV-infected patients on BMT who were followed in a hospital-based outpatient department. RESULTS: The continuous series of follow-up visits at which these 114 patients reported regular buprenorphine prescriptions accounted for 237.5 person-years of observation, i.e. 475 follow-up visits. Of the 114 patients on BMT, 43% continued BMT throughout the follow-up, 40% stopped it, and results for 17% were not available either because they did not answer the self-administered questionnaire (5%) or because they were lost to follow-up (12%). Addictive behaviours declined but buprenorphine injection misuse remained stable. Depression measured by the CESD score (RR=1.04 95%CI [1.01-1.06]), cocaine use (RR=2.48 95%CI [1.31-4.68]) and alcohol consumption exceeding 4 alcohol units (AU) per day (RR=2.29, 95%CI [1.17-4.46]) were independently associated with buprenorphine injection misuse among stabilised BMT patients. CONCLUSIONS: Despite the reduction in drug injection after starting BMT, buprenorphine injection misuse mainly involves patients with characteristics of severe addiction. Better monitoring of the illicit drug use patterns of patients on BMT may suggest new medical strategies for GPs to improve BMT outcomes.

Failure to maintain adherence to HAART in a cohort of French HIV-positive injecting drug users.

The study, carried out in the French MANIF 2000 cohort of HIV positive patients contaminated through injecting drug use, assessed the impact of patients' sociodemographic and psychological characteristics, behaviors toward drug abuse, and antiretroviral treatment characteristics on the maintenance of adherence to HAART (highly active antiretroviral therapies). A total of 96 patients (30 men and 66 women), who were initially adherent at their first visit after HAART prescription, were considered for analysis. Among these 96 patients, 22 (22.9%) experienced adherence failure defined as a self-reported, non-adherence behavior at any visit before the 18th month of treatment. Logistic regression showed that lack of a stable relationship, active drug injection, and depression were independently associated with adherence failure. Patients' counseling for facilitating maintenance of adherence to HAART over time should focus on prevention of drug use, provision of social support and consider the potential impact of difficulties with treatment on psychological well-being.

Use of buprenorphine in HIV-infected injection drug users: negligible impact on virologic response to HAART. The Manif-2000 Study Group.

Some HIV-infected injecting drug users (IDUs) on drug abuse maintenance treatment have access to highly active antiretroviral therapy (HAART); this raises questions about the effects of individual treatments on the efficacy of HAART. The French Cohort Study of HIV-infected IDUs - MANIF-2000 - allowed one to assess whether buprenorphine differentially impacts efficacy of HAART. Of the 103 HAART-treated patients, (excluding active IDUs and patients on methadone), 20 were on buprenorphine substitution treatment and 83 were ex-IDUs. A linear regression model used the differences in viral load titre before and after treatment initiation, as a dependent variable, and showed that buprenorphine treatment was not significantly associated with viral load trend. This was also the case when adjusting for other potential confounders, and suggests that there is no major short-term influence of buprenorphine on HIV viral load in HAART-treated patients.

Prevalence of drug resistant mutants and virological response to combination therapy in patients with primary HIV-1 infection.

Baseline genotype resistance analysis was carried out in 48 adults with primary HIV-1 infection between 1995 and 1998 before starting early combination therapy. Seventeen percent (8/48) of the isolates displayed key mutations conferring resistance to reverse transcriptase (RT) inhibitors such as amino acid substitutions 215Y/F (5/48,10%), 70R (3/48, 6%), 184V (2%). Two percent (1/48) had a major mutation associated with resistance to protease inhibitors (D30N). Other mutations at positions 10, 15, 20, 33, 36, 46, 63, 71, 77, 82, 93 of the protease gene were frequent (73%). Among the 46 patients who were given antiretroviral combination therapy and who responded durably to treatment after 6 and 12 months, there was no significant difference between those harboring RT mutant strains (Group I) and those with wild-type isolates (Group II). No significant difference was found at months 6 and 12 between the two groups in terms of CD4+ cell counts. These findings suggest that the presence of drug-resistant strains at the time of primary HIV-1 infection does not necessarily predict drug failure. Other factors, such as adherence to treatment, tolerance and pharmacokinetics parameters are probably major determinants of virological response in patients with early therapeutic intervention.

Intensive sequential chemotherapy (ISC 95) with growth factors and blood stem cell support in high-intermediate and high-risk (IPI 2 and IPI 3) aggressive non-Hodgkin's lymphoma: an oligocentric report on 42 patients.

We previously reported feasibility and efficacy of a monocentric pilot study of intensive sequential chemotherapy (ISC) in poor-risk aggressive non-Hodgkin's lymphoma (NHL) in patients < 60 years. To validate these results on a large cohort of patients, we designed a new and oligocentric study. After a COP (cyclophosphamide (Cy), vincristine (Vcr), prednisone (Pred) debulking, patients received four courses of high-dose CHOP (Cy, doxorubicin (Doxo), Ver, Pred), with the addition of etoposide and cisplatin during the two last courses. G-CSF was delivered after each cycle, and peripheral blood stem cells (PBSC) were used to support the two last cycles. Total duration of chemotherapy was 13 weeks, with a planned dose-intensity (DI) of 1420 mg/m2/week and 23 mg/m2/week for Cy and Doxo, respectively. Radiotherapy (involved fields) was then delivered for patients with node size > or = 5 cm at diagnosis. Forty-two patients were enrolled in this study; 36 completed the treatment and received 75% or more of the planned DI for both Cy and Doxo. Median duration of grade 4 neutropenia was 14 days (range, 2 to 28) for the regimen as a whole, and median duration of rehospitalization for febrile neutropenia was 18 days (range, 4 to 41). Overall response rate was 83%, with 29 patients (69%) in complete response (CR). Six patients failed to respond and one died of toxicity. With a median follow-up of 22.5 months (range, 10 to 42), the 3-year event-free survival (EFS) is 55% (95% CI, 39-71), while disease-free survival (DFS) is 79% (95% CI, 63-95). Ambulatory ISC is accessible and feasible in an oligocentric study. PBSC allow repeated delivery of high-dose chemotherapy cycles, and result in encouraging CR, EFS, and DFS rates for poor-risk aggressive NHL's patients.

Chlorambucil in indolent chronic lymphocytic leukemia. French Cooperative Group on Chronic Lymphocytic Leukemia.

BACKGROUND: To determine whether chlorambucil treatment benefits patients with indolent chronic lymphocytic leukemia (CLL), we conducted two randomized trials in 1535 patients with previously untreated stage A CLL. METHODS: In the first trial, 609 patients were randomly assigned to receive either daily chlorambucil or no treatment; in the second trial, 926 patients were randomly assigned to receive either intermittent chlorambucil plus prednisone or no treatment. Median follow-up for the first and second trials exceeded 11 and 6 years, respectively. The end points were overall survival, response to treatment, and disease progression. RESULTS: Treatment of indolent CLL did not increase survival in either trial. In the treated group, as compared with the untreated group, the relative risk of death was 1.14 (95 percent confidence interval, 0.92 to 1.41; P=0.23) in the first trial and 0.96 (95 percent confidence interval, 0.75 to 1.23; P=0.74) in the second trial, with 76 percent and 69 percent of patients, respectively, having a response to therapy. Although chlorambucil slowed disease progression, there was no effect on overall survival. In the untreated group in the first trial, 49 percent of patients did not have progression to more advanced disease and did not need therapy after follow-up of more than 11 years; however, 27 percent of patients with stage A CLL died of causes related to the disease. CONCLUSIONS: Chlorambucil does not prolong survival in patients with stage A CLL. Since deferring therapy until the disease progresses to stage B or C does not compromise survival, treatment of indolent CLL is unnecessary.

A prospective randomized trial of idarubicin vs daunorubicin in combination chemotherapy for acute myelogenous leukemia of the age group 55 to 75.

A prospective randomized study was conducted comparing the efficacy and toxicity of two anthracyclines for the treatment of patients with acute myeloid leukemia (AML) between 55 and 75 years. A total of 220 patients were randomized to receive as induction chemotherapy cytosine arabinoside (Ara-C: 100 mg/m2/day; continuous infusion for 7 days) combined with either daunorubicin (DNR: 50 mg/m2/day, i.v. bolus for 3 days) (n=108) or idarubicin (IDA: 8 mg/m2/day, i.v. bolus for 5 days) (n=112). The complete remission (CR) rate was similar (P=0.296) after IDA (76/112; 68%) and DNR (66/108; 61%) (P=0.3). For patients aged 55-65, the CR rate was significantly higher after IDA (39/47; 83%) than after DNR (29/50; 58%) (P=0.007). Persistent leukemia was more frequent after DNR (26/108) than after IDA (13/112; P=0.015). Hematological and extra-hematological toxicities were similar. The CR patients were given a consolidation course of chemotherapy with Ara-C: 50 mg/m2/12 h, subcutaneously for 5 days, combined with either DNR:30 mg m2/day, i.v. bolus for 3 days or IDA:8 mg/m2/day i.v. bolus for 3 days according to the initial randomization, and then received a continuous maintenance treatment for 2 years. The survival and disease-free survival (DFS) were similar in both groups; there was no difference in the risk of relapse. However, there was a trend for a longer event-free survival (EFS) in the IDA group than for the DNR patients (P=0.07). Our results seem to indicate that IDA is probably more efficient than DNR for AML patients between 55 and 75 years, and confirm the data published in other studies comparing prospectively IDA and DNR in adults.

Bone marrow transplantation in 63 adult patients with acute lymphoblastic leukemia in first complete remission.

Over a 10 year period, we transplanted 63 patients with acute lymphoblastic leukaemia (ALL) who had achieved first complete remission (CR). All were > 15 years old and 45 (71%) had at least one poor prognostic factor. Twenty-nine patients with a suitable sibling underwent autologous bone marrow transplantation (BMT). Beginning in 1984, patients without a donor received an allogeneic BMT (34 patients). Preparation consisted of cyclophosphamide (CY)/TBI (78%) or melphalan (Mel)/TBI (22%); marrow was treated in vitro in 31 patients (allogeneic: 7; autologous: 24). Kaplan-Meier estimates of the probability at 6 years of relapse, survival and DFS were 41% (allogeneic: 10%, autologous: 65%, p < 0.05), 44% (allogeneic: 62%, autologous: 26%, p = NS) and 42% (allogeneic: 62%, autologous: 27%, p < 0.06), respectively. This report confirms that allogeneic BMT permits long-term remissions giving high levels of survival when performed shortly after entering first CR while autologous BMT, when performed in the same setting, is less successful at preventing relapse. This study also confirms the high sensitivity of ALL to the graft-versus-leukemia effect provided by allogeneic BMT. Chemoradiotherapy dose intensification delivered at autologous BMT is not sufficient to prevent relapses. Autologous BMT must therefore be augmented by other approaches of which immunotherapy may be one.

[Evaluation of osteoclastic activity in multiple myeloma: results of a randomized trial studying hypocalcemia induced by human and salmon calcitonin in 49 patients]. / Evaluation de l'activité ostéoclastique dans le myélome multiple: résultats d'un essai randomisé étudiant l'hypocalcémie induite par les calcitonines humaine et de saumon chez 49 sujets.

Forty-nine subjects have been included in a randomized cross-over study evaluating acute hypocalcemia induced by calcitonin in the staging of multiple myeloma, and comparing 0.5 mg of human calcitonin and 100 IU of salmon calcitonin. Subjects were divided in 11 controls, 15 myelomas before primary treatment, 11 myelomas in plateau-phase and 12 in relapse. All the subjects had both tests with the two calcitonins at an interval of 3 days. Decrease of calcemia was important and similar in patients before primary treatment and in relapse (0.16 mmol/l mean value). Decrease was moderate in patients in plateau-phase (0.07 mmol/l mean value), similar to the decrease observed in controls. Decrease of calcemia was correlated with tumoral cellular mass in initial phase patients, but not in patients in plateau-phase. Both human and salmon calcitonins had similar effects on onset, magnitude and duration of hypocalcemia inside each group. This study confirms the interest of acute hypocalcemia test induced by calcitonin in the clinical staging of myeloma, and the similar effectiveness of both calcitonins in man.

Allogeneic or autologous bone marrow transplantation for acute lymphoblastic leukemia in first complete remission.

Forty-seven patients with high risk acute lymphoblastic leukemia (ALL) received an allogeneic (allo) or autologous (auto) bone marrow transplant (BMT). Patients in both groups were comparable in terms of age, initial presentation of ALL and induction chemotherapy. Allo patients were transplanted earlier (median 3 months after CR) than auto patients (median 6.5 months after CR). Auto patients received more consolidation chemotherapy before BMT. All patients received total body irradiation 2.2 Gy/day x 5 days after cyclophosphamide 60 mg/kg x 2 (18 allo and five auto) or melphalan 140 mg/m2 (seven allo and 17 auto). Prevention of graft-versus-host disease (GVHD) was by conventional immunosuppression in 17 patients and T cell depletion in eight. Seven patients (28%) developed moderate to severe acute GVHD. Auto marrow was treated in vitro in each case. Seven patients died in CR from BMT complications (five allo and two auto). The probability of relapse was 9% for patients receiving allo BMT and 52% for patients receiving auto BMT (p less than 0.01). The disease-free survival was 71% for allo BMT and 40% for auto BMT (p = NS). Early BMT is an effective form of consolidation for high risk patients with ALL in first CR. An allogeneic anti-leukemia effect was demonstrated in this study.

Repeated courses of high dose melphalan and unpurged autologous bone marrow transplantation in children with acute non-lymphoblastic leukemia in first complete remission.

Eleven children between the ages of 1 and 16 years with acute non-lymphoblastic leukemia (ANLL) in first remission were included in a study of double unpurged autologous bone marrow transplantation (ABMT). Prior to each ABMT patients received massive chemotherapy with melphalan at a dosage of 140 mg/m2. The first ABMT was done within a median of 4 months after the achievement of complete remission. As soon as the children had adequate hematologic recovery, a second marrow collection was done, followed by a second course of melphalan and a second ABMT. The duration of aplasia was significantly longer after the second ABMT than after the first, but the non-hematologic toxicity was relatively mild in each case and no patient died from the procedure. Four patients relapsed and seven are alive in unmaintained complete remission with a median duration of leukemia-free survival of 29 months (range 15-56 months) after the first ABMT. These data demonstrate the feasibility of repeating ABMT after melphalan in children with ANLL. The eventual impact of such therapy needs to be demonstrated in prospective randomized studies.

[Prolonged survival in multiple myeloma. Characteristics of presentation and response to treatment of 73 patients who survived 5 years or longer]. / Survie prolongée au cours du myélome multiple. Caractéristiques de présentation et de réponse au traitement de 73 malades ayant vécu 5 ans ou plus.

Data concerning the presentation and response to treatment of 73 patients with multiple myeloma who survived for 5 years or more were reviewed. At the time of diagnosis, the proportion of patients with hypercalcaemia (4%), severe anaemia (9%), renal failure (10%) or high beta 2-microglobulin levels (25%) was low. Less than one-third of our patients belonged to a "high risk" group, as defined by the three classification systems adopted: the lowest percentage of such patients (18%) was observed with the Medical Research Council classification. In all patients, but even more in those with an initially aggressive disease (P less than 0.05), obtaining a plateau (70% of the cases) or even an optimal tumoral regression with complete disappearance of monoclonal immunoglobulin (26% of the cases) seems to be a highly favourable factor. The same applies, though to a lesser degree, to slow response to chemotherapy (18 months on average). In all responders whether the remission was maintained or not by chemotherapy seemed to have no influence on the frequency (70%) and delay of relapses (4 1/2 years on average from the time of diagnosis). The risk of secondary blood disease (2 AML 1, 1 AML4, 1 RAEB, 1 ASIA, four of which were directly responsible for death) after 4 years on average of chemotherapy must be taken into consideration.
