    ABSTRACT: Poor prognosis germ-cell tumours are only cured in about half of patients. We aimed to assess whether treatment intensification based on an early tumour marker decline will improve progression-free survival for patients with germ-cell tumours. In this phase 3, multicentre, randomised trial, patients were enrolled from France (20 centres), USA (one centre), and Slovakia (one centre). Patients were eligible if they were older than 16 years, had evidence of testicular, retroperitoneal, or mediastinal non-seminomatous germ cell tumours based on histological findings or clinical evidence and highly elevated serum human chorionic gonadotropin or alfa-fetoprotein concentrations that matched International Germ Cell Cancer Consensus Group poor prognosis criteria. After one cycle of BEP (intravenous cisplatin [20 mg/m(2) per day for 5 days], etoposide [100 mg/m(2) per day for 5 days], and intramuscular or intravenous bleomycin [30 mg per day on days 1, 8, and 15]), patients' human chorionic gonadotropin and alfa-fetoprotein concentrations were measured at day 18-21. Patients with a favourable decline in human chorionic gonadotropin and alfa-fetoprotein continued BEP (Fav-BEP group) for 3 additonal cycles, whereas patients with an unfavourable decline were randomly assigned (1:1) to receive either BEP (Unfav-BEP group) or a dose-dense regimen (Unfav-dose-dense group), consisting of intravenous paclitaxel (175 mg/m(2) over 3 h on day 1) before BEP plus intravenous oxaliplatin (130 mg/m(2) over 3 h on day 10; two cycles), followed by intravenous cisplatin (100 mg/m(2) over 2 h on day 1), intravenous ifosfamide (2 g/m(2) over 3 h on days 10, 12, and 14), plus mesna (500 mg/m(2) at 0, 3, 7 and 11 h), and bleomycin (25 units per day, by continuous infusion for 5 days on days 10-14; two cycles), with granulocyte-colony stimulating factor (lenograstim) support. Centrally blocked computer-generated randomisation stratified by centre was used. The primary endpoint was progression-free survival and the efficacy analysis was done in the intention-to-treat population. The planned trial accrual was completed in May, 2012, and follow-up is ongoing. This study is registered with ClinicalTrials.gov, number NCT00104676. Between Nov 28, 2003, and May 16, 2012, 263 patients were enrolled and 254 were available for tumour marker assessment. Of these 51 (20%) had a favourable marker assessment, and 203 (80%) had an unfavourable tumour marker decline; 105 were randomly assigned to the Unfav-dose-dense group and 98 to the Unfav-BEP group. 3-year progression-free survival was 59% (95% CI 49-68) in the Unfav-dose-dense group versus 48% (38-59) in the Unfav-BEP group (HR 0·66, 95% CI 0·44-1·00, p=0·05). 3-year progression-free survival was 70% (95% CI 57-81) in the Fav-BEP group (HR 0·66, 95% CI 0·49-0·88, p=0·01 for progression-free survival compared with the Unfav-BEP group). More grade 3-4 neurotoxic events (seven [7%] vs one [1%]) and haematotoxic events occurred in the Unfav-dose-dense group compared with in the Unfav-BEP group; there was no difference in grade 1-2 febrile neutropenia (18 [17%] vs 18 [18%]) or toxic deaths (one [1%] in both groups). Salvage high-dose chemotherapy plus a stem-cell transplant was required in six (6%) patients in the Unfav-dose-dense group and 16 (16%) in the Unfav-BEP group. Personalised treatment with chemotherapy intensification reduces the risk of progression or death in patients with poor prognosis germ-cell tumours and an unfavourable tumour marker decline.

    ABSTRACT: The international phase IIIb study, ATHENA assessed the combination of bevacizumab/taxane-based chemotherapy in the first-line treatment of HER2 negative metastatic breast cancer (mBC) in real-life setting. Among the 365 patients included in France, median overall survival (OS) is 28.4 months (CI95% 24.8-33.0), with a median time from treatment start to end of study of 36,5 months (25,1-45,4). Exploratory analyses in three sub-groups show that the median OS in long responder patients (not progressing for at least one year; n = 116) is not reached. In responder patients (n = 308), median OS is 33.0 months (CI95% 28.6-37.4) and 12.4 months (CI95% 11.2-17.4) in non-responders (n = 41). In patients with mBC expressing hormone receptors (HR+), treated with first-line hormone therapy before inclusion (n = 87) median OS in is 23.2 months (CI95% 19.6-28.6), and 35.3 months (CI95% 32.2-not reached); P = 0.004 in patients treated first with chemotherapy + bevacizumab (n = 179). The safety analysis in the various sub-groups of grade 3-5 adverse events of particular interest to bevacizumab of this study was comparable to the safety data of randomized phase III studies.

    ABSTRACT: High-dose chemotherapy (HDCT) is an effective salvage treatment for germ-cell tumors (GCTs) patients. In the first salvage setting, 30%-70% of patients may achieve durable remissions. Even when HDCT is administered as subsequent salvage treatment, up to 20% of patients may still be definitively cured. However, patients with refractory/relapsed disease still have a very poor long-term prognosis, requiring earlier intervention of HDCT.

    ABSTRACT: The standard treatment for patients with metastatic GCT relapsing after first-line chemotherapy is based on a cisplatin and ifosfamide-containing 3-drug regimen, which usually yields a complete response (CR) rate <50%. As gemcitabine consistently displayed activity in patients with advanced GCT and as synergy with cisplatin was reported, we integrated this drug into the salvage triplet regimen and assessed its activity in this phase II study. The GIP regimen consisted in gemcitabine 1000 mg/m(2) day 1 and 5, ifosfamide 1200 mg/m(2)/d day 1-5, cisplatin 20 mg/m(2)/d, day 1-5, G-CSF 263 µg/d day 7-15, repeated every 3 weeks for 4 cycles. Eligibility criteria were that patients had favorable prognostic factors to conventional-dose salvage chemotherapy including a testis primary tumor and a previous complete response (CR) to first-line chemotherapy for metastatic disease. The primary endpoint was the CR rate and a two-stage Simon design was used. 37 patients were accrued and 29 (78%) achieved a favorable response, including a CR in 20 (54%) and a partial response with normalization of tumor markers (PRm-) in 9 (24%). With a median follow-up of 53 months (13-81), the 2-year overall survival rate is 73% (57%-84%) and the continuous progression-free survival rate is 51% (35%-66%). Myelosuppression was the main toxicity including febrile neutropenia in 8 (22%) patients and 18 (50%) cases required platelet infusion. No grade 3-4 peripheral neurotoxicity or renal toxicity occurred. Two patients died of treatment-related toxicity, one of them with cancer progression. In a multicenter context, four cycles of the GIP regimen achieved a high CR rate in patients with relapsed testicular GCT. The GIP regimen avoided severe neurotoxicity and yielded a high survival rate. NCT00127049.

    ABSTRACT: Background The expanded access program and anecdotal cases suggested sunitinib is safe in RCC patients with BM and might have worthwhile activity. Patients and Methods In a phase II trial, patients with untreated BM received the standard regimen of sunitinib. The primary end point was objective response (OR) rate in BM after 2 cycles. An OR rate of 35% was prospectively defined as the minimum needed to warrant further investigation. According to Simon's optimal 2-stage design, at least 3 of the initial 15 patients had to have an OR for accrual to continue. Results Among 16 evaluable patients, 1 had a complete response outside the central nervous system (CNS). CNS disease was stabilized in 5 (31%). However, no BM showed an OR. Therefore, no further accrual took place. Median time to progression was 2.3 months and overall survival was 6.3 months. There was 1 toxic death, from peritonitis with gastric perforation. Three patients experienced at least 1 treatment-related grade 3 or greater toxicity but no neurological adverse events were attributable to sunitinib. Conclusion Although tolerability was acceptable in RCC patients with previously untreated BM, sunitinib has limited efficacy in this setting.

    ABSTRACT: Brain metastases (BM) can affect up to 45 % of a high-risk breast cancer (BC) population. Liposomal doxorubicin (LD)-based chemotherapy has demonstrated efficacy in the treatment of BC and LD crosses the blood-brain barrier. The aim of this retrospective study is to evaluate the efficacy of the LD-cyclophosphamide (CTX) combination in BM related to BC. Patients diagnosed with BM related to BC and treated with the LD-CTX combination were eligible. BM objective response rate (BM-ORR), BM disease control rate (BM-DCR), BM progression-free survival, overall survival (OS) and safety were analyzed. 29 patients were eligible. The median time from metastatic diagnosis to brain involvement was 12 months. BM was more frequently observed in HER2+ patients. On average, three courses of chemotherapy were administered without grade 3-4 limiting adverse events. After three cycles, BM-ORR and BM-DCR were 41.4 and 58.6 % respectively versus 50 and 62.5 % when no prior radiotherapy was administered. From BM diagnosis, OS was 23 months. A high BM-ORR is observed with the LD-CTX combination in patients with BM related to BC. This is an attractive therapeutic option for these patients, especially when no prior whole brain radiotherapy has been administered.

    ABSTRACT: Toxicity, which is a key parameter in the evaluation of cancer treatments, can be underestimated by clinicians. We investigated differences between patients and physicians in reporting adverse events of androgen deprivation therapy (ADT) with or without docetaxel in a multicentre phase III trial in non-castrate metastatic prostate cancer. The 385 patients included were invited to complete a 26-symptom questionnaire 3 and 6months after the start of treatment, among which eighteen symptoms were also assessed by physicians, reported in medical records and graded using the Common Toxicity Criteria of the National Cancer Institute. Positive and negative agreements as well as Kappa concordance coefficients were computed. Data were available for 220 and 165 patients at 3 and 6months respectively. Physicians systematically under-reported patients' symptoms. Positive agreement rates (at respectively 3 and 6months) for the five most commonly reported symptoms were: 61.0% and 64.3% hot flushes, 50.0% and 43.6% fatigue, 29.4% and 31.1% sexual dysfunction, 24.4% and 14.4% weigh gain/loss, 16.7% and 19.3% for joint/muscle pain. For symptoms most frequently reported as disturbing or very disturbing by patients, the clinicians' failure to report them ranged from 50.8% (hot flushes) to 89.5% (joint/muscle pain) at 3months, and from 48.2% (hot flushes) to 88.4% (joint/muscle pain) at 6months. Physicians often failed to report treatment-related symptoms, even the most common and disturbing ones. Patients' self-evaluation of toxicity should be used in clinical trials to improve the process of drug assessment in oncology.

    ABSTRACT: To evaluate the overall benefits of non-taxane chemotherapies in a non-selected population including unfit patients presenting with symptoms and pain. This randomised phase 2 study reports data from 92 patients (52% > 70 yrs-old; 40% PS II) previously treated with taxane-based chemotherapy and collected at 15 centres in France. Patients received intravenous mitoxantrone (MTX), oral vinorelbine (VN), or oral etoposide (EP) associated with oral prednisone. Palliative benefit (pain response without progression of the disease), biological and tumoral responses, and toxicity profile as well as geriatric assessment (in elderly population) were analysed on an intention-to-treat basis. The palliative response rate was 17% for the whole population, and reached 29% when considering the MTX arm. The control of pain was achieved in 40% of the patients. The median overall survival was 10.4 months, and was longer in palliative responders. Few grade 3-4 toxicities were observed. The subgroup analysis of elderly patients showed similar results regarding the number and dose-intensity of treatments, efficacy and safety. In a population including frailty and/or elderly patients, who are poorly represented in most of the clinical studies, non-taxane chemotherapy may remain a relevant option for metastatic prostate cancer having relapsed after a docetaxel-based regimen.While new treatment options are now approved, decision-making process should take into account the expected benefit/risk ratio based on the patient status.

    ABSTRACT: To evaluate the outcomes following targeted therapies in the management of metastatic renal cell carcinoma (mRCC), through the study of overall survival (OS) and progression-free (PFS). We retrospectively included 78 patients treated with targeted therapies for mRCC at the Paul Papin Cancer Institute from 2004 to 2009. Overall survival (OS), progression free survival (PFS), response to treatment, occurrence of grade III and IV side effects, were analyzed following first and second line treatments. Median follow-up was 33 months [5-236], and 41 patients died (52.6%). Median OS was 36 months [95% CI 29-43]. The median PFS was 14 months [95% CI 6.71-21.29] for sunitinib, 38 months [95% CI 11.41-64.59] for bevacizumab with interferon (IFN), and 8 months [95% CI 0-17.03] for IFN alone. A partial reduction, stabilization or increase in tumor size was observed for 19.2%, 47.4% and 25.6% of cases. A second line treatment was given for 53 patients. They received either sunitinib (n=20, 37.8%), bevacizumab with IFN (n=7, 13.2%), sorafenib (n=17, 32.2%), temsirolimus (n=3, 5.6%) or other molecules (n=6 11.2%). Grade III or IV side effects were observed for 14.1%, 28.3% and 18.2% of the patients following first, second and third line treatment, respectively. Outcomes of targeted therapies in our center upheld the literature data. These therapies allow a benefit survival versus immunotherapy, with sometimes large side-effect.

    ABSTRACT: PURPOSE: A prospective phase II multicenter study was performed in two steps in paclitaxel-treated ovarian cancer patients in France. A French version of the four-item Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx) questionnaire was validated. This was then used to evaluate neurotoxicity in relation to erythropoietin treatment. METHODS: Patients received standard second-line paclitaxel-based chemotherapy and erythropoietin for anemia. Neurotoxicity and hemoglobin levels were evaluated every cycle with the FACT/GOG-Ntx and NCI-CTCAE. The translated questionnaire was tested in 20 patients to confirm the translation accuracy. The final questionnaire was validated in 98 patients with internal consistency (Cronbach's coefficient) and item correlation (Pearson's r coefficient) tests. Neurotoxicity severity was analyzed according to erythropoietin intake (first three cycles versus no or late intake) and correlated with anemia. RESULTS: Patients received a median of six paclitaxel cycles (range 1-9). Neurotoxicity was validated in 484 questionnaires. Internal consistency was excellent with Cronbach's coefficients of ≥0.89 at inclusion, after 3 cycles and at study end. Inter-question correlation was high with Pearson's coefficients of 0.65-0.85. FACT/GOG-Ntx and NCI-CTCAE severity scoring was similar. Globally, the incidence of severe neurotoxicity (FACT/GOG-Ntx and NCI-CTCAE) was found significantly higher in patients with severe anemia. Of 98 evaluable patients, 31 received erythropoietin during the first three cycles. Mean hemoglobin level was significantly lower in this group from baseline to cycle 4; however, these anemic patients with early EPO intake did not develop an increase rate of severe neurotoxicity. CONCLUSIONS: The French FACT/GOG-Ntx questionnaire is a reliable and valid tool for assessing chemotherapy-induced neuropathy. This study raises the possibility that erythropoietin might play a neuroprotective role when administered with paclitaxel.

    ABSTRACT: BACKGROUND: Early chemotherapy might improve the overall outcomes of patients with metastatic non-castrate (ie, hormone-sensitive) prostate cancer. We investigated the effects of the addition of docetaxel to androgen-deprivation therapy (ADT) for patients with metastatic non-castrate prostate cancer. METHODS: In this randomised, open-label, phase 3 study, we enrolled patients in 29 centres in France and one in Belgium. Eligible patients were older than 18 years and had histologically confirmed adenocarcinoma of the prostate and radiologically proven metastatic disease; a Karnofsky score of at least 70%; a life expectancy of at least 3 months; and adequate hepatic, haematological, and renal function. They were randomly assigned to receive to ADT (orchiectomy or luteinising hormone-releasing hormone agonists, alone or combined with non-steroidal antiandrogens) alone or in combination with docetaxel (75 mg/m(2) intravenously on the first day of each 21-day cycle; up to nine cycles). Patients were randomised in a 1:1 ratio, with dynamic minimisation to minimise imbalances in previous systemic treatment with ADT, chemotherapy for local disease or isolated rising concentration of serum prostate-specific antigen, and Glass risk groups. Patients, physicians, and data analysts were not masked to treatment allocation. The primary endpoint was overall survival. Efficacy analyses were done by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00104715. FINDINGS: Between Oct 18, 2004, and Dec 31, 2008, 192 patients were randomly allocated to receive ADT plus docetaxel and 193 to receive ADT alone. Median follow-up was 50 months (IQR 39-63). Median overall survival was 58·9 months (95% CI 50·8-69·1) in the group given ADT plus docetaxel and 54·2 months (42·2-not reached) in that given ADT alone (hazard ratio 1·01, 95% CI 0·75-1·36). 72 serious adverse events were reported in the group given ADT plus docetaxel, of which the most frequent were neutropenia (40 [21%]), febrile neutropenia (six [3%]), abnormal liver function tests (three [2%]), and neutropenia with infection (two [1%]). Four treatment-related deaths occurred in the ADT plus docetaxel group (two of which were neutropenia-related), after which the data monitoring committee recommended treatment with granulocyte colony-stimulating factor. After this recommendation, no further treatment-related deaths occurred. No serious adverse events were reported in the ADT alone group. INTERPRETATION: Docetaxel should not be used as part of first-line treatment for patients with non-castrate metastatic prostate cancer.

    ABSTRACT: BACKGROUND: Although the taxanes paclitaxel and docetaxel are among the most active agents for the treatment of a wide range of cancers, tumours often develop resistance to these treatments. Cabazitaxel is a novel taxane active in both preclinical models of chemotherapy-sensitive and -resistant human tumours and patients with advanced prostate cancer that progressed following docetaxel treatment. AIM: To establish the maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs) of cabazitaxel. PATIENTS AND METHODS: Cabazitaxel was administered every 3weeks to patients with advanced solid tumours. The design allowed intrapatient dose escalation. The primary objective was to determine the MTD. Secondary objectives were to describe the safety profile, establish an appropriate dose, determine the pharmacokinetic (PK) profile of cabazitaxel, and assess antitumour activity. RESULTS: Twenty-one patients were recruited. The MTD was reached at 30mg/m(2), at which three of five patients experienced haematologic DLTs during the first cycle. DLTs during subsequent cycles were mainly haematologic and reported at 25 and 30mg/m(2) dosing levels. Nail disorders and severe alopecia were not reported, and neurotoxicity, fluid retention and hypersensitivity were mild and infrequent. Cabazitaxel demonstrated linear PK, a triphasic elimination profile, with a long half-life and high clearance. Of the 19 patients evaluable for response, one unconfirmed partial response and six occurrences of stable disease were reported. CONCLUSIONS: The 25mg/m(2) dose of cabazitaxel was recommended for use in future clinical studies. In this study, cabazitaxel had an acceptable tolerability profile and activity in cervical, colorectal, endometrial and lung cancers.

    ABSTRACT: The efficacy of the combination bevacizumab-chemotherapy in the first-line treatment of metastatic breast cancer (mBC) was demonstrated in several randomized clinical trials. However, limited safety data is available in daily medical practice. ATHENA is an international phase-IIIb study conducted in 2,251 patients with locally advanced or mBC, treated in first-line with bevacizumab combined with taxanes-based chemotherapy. The primary objective is safety assessment. In France, 365 patients were included. Their median age was 56 years (24-93 years) and ECOG performance status was 0 or 1 in 93.9% of patients. Bevacizumab was essentially combined with a taxanes monotherapy: docetaxel (37.3%) or paclitaxel (28.8%) or taxanes-based combination therapy (9.4%). The most frequent grade superior or equal to 3 adverse event (AE) was neutropenia (34.5%). Grade superior or equal to 3 AEs of special interest related to bevacizumab were arterial and venous thromboembolism (5.1%), high blood pressure (4.2%), proteinuria (2.3%) and hemorrhage (2%). Median time to progression was 9.5 months (95% CI: 8.8-10.4). The safety profile and the efficacy of the combination bevacizumab-taxanes in a population more representative of daily oncology practice in France are comparable to those reported in clinical trials in mBC.

    ABSTRACT: To assess docetaxel-estramustine in patients with localised high-risk prostate cancer. After staging pelvic lymph node dissection, patients with high-risk prostate cancer randomly received androgen deprivation therapy (ADT) (3 years)+DE (4 cycles of docetaxel 70 mg/m(2)/3 weeks+estramustine 10mg/kg/dd1-5) or ADT alone. Local therapy was administered at 3 months. Four hundred and thirteen patients were accrued: T3-T4 (67%), Gleason score ~8 (42%), PSA >20 ng/mL (59%), pN+ (29%). In the chemotherapy arm, 94% of patients received the planned four cycles of docetaxel. Local treatment consisted of radiotherapy in 358 patients (87%) (median dose 74 Gy in both arms). ADT was given for 36 months in both arms. A PSA response (PSA ~0.2 ng/mL after 3 months of treatment) was obtained in 34% and 15% in the ADT+DE arm and in the ADT arm, respectively (p<0.0001). Febrile neutropenia occurred in only 2%. Moderate to severe hot flashes occurred less often in the ADT+DE arm (2% versus 22%; p<0.001). There was no toxicity-related death, no secondary leukaemia, and no excess second cancers. Chemotherapy had a negative impact on quality of life (global health status, p = 0.01; fatigue, p = 0.003; role functioning, p = 0.003; social functioning, p = 0.006) at 3 months but this effect disappeared at 1 year. Docetaxel-estramustine can be combined safely with standard therapy in high-risk prostate cancer, with a promising PSA response rate and no negative impact on quality of life after 1 year. Long-term follow-up is required to assess the impact on relapse and survival.

    ABSTRACT: A dose-dense strategy has been considered to improve results of adjuvant chemotherapy for breast cancer. This randomised phase II trial investigated the feasibility of this approach with sequential anthracyclines and taxanes-based chemotherapy. Patients with high-risk node-positive breast cancer were treated with three cycles of fluorouracil 500 mg m(-2), epirubicin 100 mg m(-2), cyclophosphamide 500 mg m(-2) (FEC 100) followed by three cycles of docetaxel 100 mg m(-2) delivered at 2-weekly intervals supported by primary prophylaxis with filgrastim. All patients were randomised to either uninterrupted treatment (arm A) or to have a 2-week additional period of rest between the FEC and docetaxel (arm B). The primary endpoint was the rate of success of chemotherapy delivery. Using a two-stage Fleming design, 120 patients were required with one interim analysis. In March 2005, enrolment was stopped into arm A after the observation of severe skin toxicities. Following the planned interim analysis, the study was closed because of the high rate of grade 3/4 skin toxicities in both arms (arm A: 32.4% and arm B: 18.9%). Sequential dose-dense FEC 100 followed by docetaxel 100 mg m(-2) is not feasible. Feasibility still depends largely on several factors including the choice of drugs, dosage and sequence of administration.

    ABSTRACT: We used data from 886 patients from the CAELYX in Platinum Sensitive Ovarian Patients (CALYPSO) trial, recruited between April 2005 and September 2007, to examine the role of early decline in cancer antigen 125 (CA125) and early tumor response as prognostic factors and surrogates for superiority of treatment with carboplatin-pegylated liposomal doxorubicin (CPLD) compared with carboplatin-paclitaxel (CP) in a landmark analysis. Progression-free survival (PFS) was estimated by Kaplan-Meier analyses. We used univariate and multivariable Cox proportional hazards analyses to assess early decline and early response as surrogates for CPLD treatment benefit compared with CP. All statistical tests were two-sided. Early decline (defined as rate of CA125 decrease of at least 50% per month) was associated with improved PFS (adjusted hazard ratio [HR] for progression = 0.81, 95% confidence interval [CI] = 0.67 to 0.97, P = .02) but early response (complete or partial responses) was not. CPLD was associated with improved PFS compared with CP (HR = 0.82, 95% CI = 0.69 to 0.96, P = .01). However, fewer CPLD patients had an early decline (161 [37.4%] vs 233 [51.2%], P < .001) or an early response (146 [33.9%] vs 176 [38.7%], P = .14) compared with CP patients. The PFS for CPLD patients did not change statistically significantly after adjustment for early decline (adjusted HR = 0.80, 95% CI = 0.68 to 0.94, P = .007). These findings are opposite to what would be expected if these markers were good surrogates for treatment benefit.

    ABSTRACT: Combining targeted treatments for renal cell carcinoma has been suggested as a possible method to improve treatment efficacy. We aimed to assess the potential synergistic or additive effect of the combination of bevacizumab, directed against the VEGF receptor, and temsirolimus, an mTOR inhibitor, in metastatic renal cell carcinoma. TORAVA was an open-label, multicentre randomised phase 2 study undertaken in 24 centres in France. Patients aged 18 years or older who had untreated metastatic renal cell carcinoma were randomly assigned (2:1:1) to receive the combination of bevacizumab (10 mg/kg every 2 weeks) and temsirolimus (25 mg weekly; group A), or one of the standard treatments: sunitinib (50 mg/day for 4 weeks followed by 2 weeks off; group B), or the combination of interferon alfa (9 mIU three times per week) and bevacizumab (10 mg/kg every 2 weeks; group C). Randomisation was done centrally and independently from other study procedures with computer-generated permuted blocks of four and eight patients stratified by participating centre and Eastern Cooperative Oncology Group performance status. The primary endpoint was progression-free survival (PFS) at 48 weeks (four follow-up CT scans), which was expected to be above 50% in group A. Analysis was by intention to treat. The study is ongoing for long-term overall survival. This study is registered with ClinicalTrials.gov, number NCT00619268. Between March 3, 2008 and May 6, 2009, 171 patients were randomly assigned: 88 to the experimental group (group A), 42 to group B, and 41 to group C. PFS at 48 weeks was 29.5% (26 of 88 patients, 95% CI 20.0-39.1) in group A, 35.7% (15 of 42, 21.2-50.2) in group B, and 61.0% (25 of 41, 46.0-75.9) in group C. Median PFS was 8.2 months (95% CI 7.0-9.6) in group A, 8.2 months (5.5-11.7) in group B, and 16.8 months (6.0-26.0) in group C. 45 (51%) of 88 patients in group A stopped treatment for reasons other than progression compared with five (12%) of 42 in group B and 15 (38%) of 40 in group C. Grade 3 or worse adverse events were reported in 68 (77%) of 88 patients in group A versus 25 (60%) of 42 in group B and 28 (70%) of 40 in group C. Serious adverse events were reported in 39 (44%) of 88, 13 (31%) of 42, and 18 (45%) of 40 patients in groups A, B, and C, respectively. The toxicity of the temsirolimus and bevacizumab combination was much higher than anticipated and limited treatment continuation over time. Clinical activity was low compared with the benefit expected from sequential use of each targeted therapy. This combination cannot be recommended for first-line treatment in patients with metastatic renal cell carcinoma. French Ministry of Health and Wyeth Pharmaceuticals.

    ABSTRACT: There are limited data on treatment outcomes in the growing population of elderly patients with locally recurrent/metastatic breast cancer (LR/mBC). To gain information on first-line bevacizumab combined with chemotherapy in the elderly, we analyzed data from the ATHENA trial in routine oncology practice. Patients with human epidermal growth factor receptor-2-negative LR/mBC received first-line bevacizumab with standard chemotherapy until disease progression, unacceptable toxicity, or physician/patient decision. We carried out a subgroup analysis of safety and efficacy in patients aged≥70 years. Possible correlations between tolerability and baseline comorbidities or Eastern Cooperative Oncology Group status were explored. Bevacizumab was combined with single-agent paclitaxel in 46% of older patients. Only hypertension and proteinuria were more common in older than in younger patients (grade≥3 hypertension: 6.9% versus 4.2%, respectively; grade≥3 proteinuria: 4.0% versus 1.5%, respectively). Grade≥3 arterial/venous thromboembolism occurred in 2.9% versus 3.3%, respectively. Further analysis revealed no relationship between baseline presence and severity of hypertension and risk of developing hypertension during bevacizumab-containing therapy. Median time to progression was 10.4 months in patients aged≥70 years. These findings suggest that bevacizumab-containing therapy is tolerable and active in patients aged≥70 years. Hypertension was more common than in younger patients but was manageable. We find no evidence precluding the use of bevacizumab in older patients, including those with hypertension, although age may influence chemotherapy choice.
