Regulatory T-Cell Responses to Low-Dose Interleukin-2 in HCV-Induced Vasculitis

BACKGROUND Patients with vasculitis induced by the hepatitis C virus (HCV) have reduced levels of regulatory T cells (Tregs). Resolution of HCV infection correlates with cure of vasculitis and the recovery of Treg levels. We reasoned that interleukin-2, a cytokine that promotes Treg survival and function, could be beneficial for patients with vasculitis that is resistant to HCV therapy. METHODS We investigated the safety and immunologic effects of the administration of low-dose interleukin-2 in a prospective open-label, phase 1-phase 2a study. Ten patients with HCV-induced vasculitis that was refractory to conventional antiviral therapy, rituximab therapy, or both and who were not receiving glucocorticoid or immunosuppressant therapy, received one course of interleukin-2 (1.5 million IU per day) for 5 days, followed by three 5-day courses of 3 million IU per day at weeks 3, 6, and 9. Both the safety of the treatment and its effectiveness were evaluated, the latter by monitoring the Treg response and the clinical signs of HCV vasculitis. RESULTS No adverse events reached a level higher than grade 1. The treatment did not induce effector T-cell activation, vasculitis flare, or increased HCV viremia. We observed a reduction in cryoglobulinemia in 9 of 10 patients and improvement of vasculitis in 8 of 10. Administration of low-dose interleukin-2 was followed by an increase in the percentage of CD4+, CD25(high), forkhead box P3 (FOXP3+) Tregs [E(max) (maximum value)÷baseline value×100=420%] with potent suppressive activity in all subjects and by a concomitantly decreased proportion of marginal-zone B cells. Transcriptome studies of peripheral-blood mononuclear cells revealed that interleukin-2 induced a global attenuation of the signatures for inflammation and oxidative stress mediators. CONCLUSIONS The trial showed that low-dose interleukin-2 was not associated with adverse effects and led to Treg recovery and concomitant clinical improvement in patients with HCV-induced vasculitis, an autoimmune condition.

Pegylated Liposomal Doxorubicin and Carboplatin Compared With Paclitaxel and Carboplatin for Patients With Platinum-Sensitive Ovarian Cancer in Late Relapse

PURPOSE This randomized, multicenter, phase III noninferiority trial was designed to test the efficacy and safety of the combination of pegylated liposomal doxorubicin (PLD) with carboplatin (CD) compared with standard carboplatin and paclitaxel (CP) in patients with platinum-sensitive relapsed/recurrent ovarian cancer (ROC). PATIENTS AND METHODS Patients with histologically proven ovarian cancer with recurrence more than 6 months after first- or second-line platinum and taxane-based therapies were randomly assigned by stratified blocks to CD (carboplatin area under the curve [AUC] 5 plus PLD 30 mg/m(2)) every 4 weeks or CP (carboplatin AUC 5 plus paclitaxel 175 mg/m(2)) every 3 weeks for at least 6 cycles. Primary end point was progression-free survival (PFS); secondary end points were toxicity, quality of life, and overall survival. RESULTS Overall 976 patients were recruited. With median follow-up of 22 months, PFS for the CD arm was statistically superior to the CP arm (hazard ratio, 0.821; 95% CI, 0.72 to 0.94; P = .005); median PFS was 11.3 versus 9.4 months, respectively. Although overall survival data are immature for final analysis, we report here a total of 334 deaths. Overall severe nonhematologic toxicity (36.8% v 28.4%; P < .01) leading to early discontinuation (15% v 6%; P < .001) occurred more frequently in the CP arm. More frequent grade 2 or greater alopecia (83.6% v 7%), hypersensitivity reactions (18.8% v 5.6%), and sensory neuropathy (26.9% v 4.9%) were observed in the CP arm; more hand-foot syndrome (grade 2 to 3, 12.0% v 2.2%), nausea (35.2% v 24.2%), and mucositis (grade 2-3, 13.9% v 7%) in the CD arm. CONCLUSION To our knowledge, this trial is the largest in recurrent ovarian cancer and has demonstrated superiority in PFS and better therapeutic index of CD over standard CP.

Androgen-deprivation therapy alone or with docetaxel in non-castrate metastatic prostate cancer (GETUG-AFU 15): a randomised, open-label, phase 3 trial

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.

Immediate versus deferred chemotherapy after radical cystectomy in patients with pT3?pT4 or N+ M0 urothelial carcinoma of the bladder (EORTC 30994): an intergroup, open-label, randomised phase 3 trial

BACKGROUND Patients with muscle-invasive urothelial carcinoma of the bladder have poor survival after cystectomy. The EORTC 30994 trial aimed to compare immediate versus deferred cisplatin-based combination chemotherapy after radical cystectomy in patients with pT3-pT4 or N+ M0 urothelial carcinoma of the bladder. METHODS This intergroup, open-label, randomised, phase 3 trial recruited patients from hospitals across Europe and Canada. Eligible patients had histologically proven urothelial carcinoma of the bladder, pT3-pT4 disease or node positive (pN1-3) M0 disease after radical cystectomy and bilateral lymphadenectomy, with no evidence of any microscopic residual disease. Within 90 days of cystectomy, patients were centrally randomly assigned (1:1) by minimisation to either immediate adjuvant chemotherapy (four cycles of gemcitabine plus cisplatin, high-dose methotrexate, vinblastine, doxorubicin, and cisplatin [high-dose MVAC], or MVAC) or six cycles of deferred chemotherapy at relapse, with stratification for institution, pT category, and lymph node status according to the number of nodes dissected. Neither patients nor investigators were masked. Overall survival was the primary endpoint; all analyses were by intention to treat. The trial was closed after recruitment of 284 of the planned 660 patients. This trial is registered with ClinicalTrials.gov, number NCT00028756. FINDINGS From April 29, 2002, to Aug 14, 2008, 284 patients were randomly assigned (141 to immediate treatment and 143 to deferred treatment), and followed up until the data cutoff of Aug 21, 2013. After a median follow-up of 7.0 years (IQR 5.2-8.7), 66 (47%) of 141 patients in the immediate treatment group had died compared with 82 (57%) of 143 in the deferred treatment group. No significant improvement in overall survival was noted with immediate treatment when compared with deferred treatment (adjusted HR 0.78, 95% CI 0.56-1.08; p=0.13). Immediate treatment significantly prolonged progression-free survival compared with deferred treatment (HR 0.54, 95% CI 0.4-0.73, p<0.0001), with 5-year progression-free survival of 47.6% (95% CI 38.8-55.9) in the immediate treatment group and 31.8% (24.2-39.6) in the deferred treatment group. Grade 3-4 myelosuppression was reported in 33 (26%) of 128 patients who received treatment in the immediate chemotherapy group versus 24 (35%) of 68 patients who received treatment in the deferred chemotherapy group, neutropenia occurred in 49 (38%) versus 36 (53%) patients, respectively, and thrombocytopenia in 36 (28%) versus 26 (38%). Two patients died due to toxicity, one in each group. INTERPRETATION Our data did not show a significant improvement in overall survival with immediate versus deferred chemotherapy after radical cystectomy and bilateral lymphadenectomy for patients with muscle-invasive urothelial carcinoma. However, the trial is limited in power, and it is possible that some subgroups of patients might still benefit from immediate chemotherapy. An updated individual patient data meta-analysis and biomarker research are needed to further elucidate the potential for survival benefit in subgroups of patients.

Complete Remission With Tyrosine Kinase Inhibitors in Renal Cell Carcinoma

PURPOSE Complete remission (CR) is uncommon during treatment for metastatic renal cell carcinoma (mRCC) with tyrosine kinase inhibitors (TKIs), but it may occur in some patients. It remains a matter of debate whether therapy should be continued after CR. METHODS A multicenter, retrospective analysis of a series of patients with mRCC who obtained CR during treatment with TKIs (sunitinib or sorafenib), either alone or with local treatment (surgery, radiotherapy, or radiofrequency ablation), was performed. RESULTS CR was identified in 64 patients; 36 patients had received TKI treatment alone and 28 had also received local treatment. Most patients had clear cell histology (60 of 64 patients), and all had undergone previous nephrectomy. The majority of patients were favorable or intermediate risk; however, three patients were poor risk. Most patients developed CR during sunitinib treatment (59 of 64 patients). Among the 36 patients who achieved CR with TKI alone, eight continued TKI treatment after CR, whereas 28 stopped treatment. Seventeen patients who stopped treatment (61%) are still in CR, with a median follow-up of 255 days. Among the 28 patients in CR after TKI plus local treatment, 25 patients stopped treatment, and 12 of these patients (48%) are still in CR, with a median follow-up of 322 days. CONCLUSION CR can occur after TKI treatment alone or when combined with local treatment. CR was observed at every metastatic site and in every prognostic group.

Quality of Life in Long-Term Survivors of Testicular Cancer: A Population-Based Case-Control Study

PURPOSE To evaluate quality of life and social problems in long-term survivors of testicular cancer. PATIENTS AND METHODS In 1998, 71 testicular cancer survivors (cases) identified from the Calvados General Tumor Registry were enrolled onto a case-control study. One hundred nineteen healthy control subjects (controls), matched by age and location of residence, were selected at random from electoral rolls. Three self-administered questionnaires were used: two health-related quality-of-life questionnaires (Short Form-36 and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 core questionnaires) and one life situation questionnaire. Specific questions concerning sexuality were also added. RESULTS With a mean follow-up of 11 years, health-related quality-of-life scores did not differ significantly between cases and controls, nor did general symptom scores. Psychosocial problems were reported equally by cases and controls. Cases reported more modification of sexual life (P =.04) with decreased sexual enjoyment (P <.01), decreased desire (P =.02), and infertility (P <.01). Cases did not report more divorce than controls; they reported fewer changes in relationships with friends (P =.03). Although a similar proportion of cases and controls were at work, cases expressed less ambitious professional plans (P =.002). Cases had greater difficulty in borrowing from banks (P <.001). CONCLUSION French long-term survivors of testicular cancer do not express more impairment of health-related quality of life or familial or professional life in comparison with healthy men. They did have more sexual life problems and found difficulty in borrowing from banks. This information should be used by practitioners to help their patients cope with their disease and return to normal life.

Androgen Deprivation Therapy (ADT) Plus Docetaxel Versus ADT Alone in Metastatic Non castrate Prostate Cancer: Impact of Metastatic Burden and Long-term Survival Analysis of the Randomized Phase 3 GETUG-AFU15 Trial

BACKGROUND The role of chemotherapy in metastatic non castrate prostate cancer (mNCPC) is debated. Survival benefits of docetaxel (D) added to androgen-deprivation therapy (ADT) were shown in the CHAARTED trial in patients with metastatic high-volume disease (HVD). OBJECTIVE To assess the impact of metastatic burden and to update overall survival (OS) data of the GETUG-AFU15 study. DESIGN, SETTING, AND PARTICIPANTS Randomized phase 3 trial of ADT plus D versus ADT alone in 385 mNCPC patients; median follow-up of 7 yr. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Primary end point was OS. Secondary end points were biochemical progression-free survival (bPFS) and radiographic progression-free survival (rPFS). Retrospective analysis was by tumor volume. RESULTS AND LIMITATIONS After a median follow-up of 83.9 mo, median OS in the overall population was 62.1 mo (95% confidence interval [CI], 49.5-73.7) and 48.6 mo (95% CI, 40.9-60.6) for ADT plus D and ADT arms, respectively (hazard ratio [HR]: 0.88 [95% CI, 0.68-1.14]; p=0.3). Median OS in ADT plus D and ADT arms, respectively, was for HVD patients: 39.8 mo (95% CI, 28.0-53.4) versus 35.1 mo (95% CI, 29.9-43.6) (HR: 0.78 [95% CI, 0.56-1.09]; p=0.14), for low-volume disease (LVD) patients; median was not reached (NR; 95% CI, 69.5-NR) and 83.4 mo (95% CI, 61.8-NR) (HR: 1.02 [95% CI, 0.67-1.55]; p=0.9). For upfront metastatic patients, OS was 52.6 mo (95% CI, 43.3-66.8) and 41.5 mo (95% CI, 36.3-54.5), respectively (HR: 0.93 [95% CI, 0.69-1.25]; p=0.6). The bPFS (HR: 0.73 [95% CI, 0.56-0.94]; p=0.014) and rPFS (HR: 0.75 [95% CI, 0.58-0.97]; p=0.030) were significantly longer in the ADT plus D arm. Limitations included the retrospective analysis of metastatic extent and the lack of statistical power to detect a significant difference in subgroups. CONCLUSIONS The post hoc analyses of the GETUG-AFU15 study demonstrated a nonsignificant 20% reduction in the risk of death in the HVD subgroup. Patients with LVD had no survival improvement with early D. PATIENT SUMMARY In this study, docetaxel added to castration did not improve survival in patients with metastatic hormone-sensitive prostate cancer, partly due to methodological issues. However, early chemotherapy should be discussed with all patients, given the data of three randomized trials including GETUG-AFU15.

Patient-Reported Outcome Results From the Open-Label Phase III AURELIA Trial Evaluating Bevacizumab-Containing Therapy for Platinum-Resistant Ovarian Cancer

PURPOSE To determine the effects of bevacizumab on patient-reported outcomes (PROs; secondary end point) in the AURELIA trial. PATIENTS AND METHODS Patients with platinum-resistant ovarian cancer were randomly assigned to chemotherapy alone (CT) or with bevacizumab (BEV-CT). PROs were assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Ovarian Cancer Module 28 (EORTC QLQ-OV28) and Functional Assessment of Cancer Therapy-Ovarian Cancer symptom index (FOSI) at baseline and every two or three cycles (8/9 weeks) until disease progression. The primary PRO hypothesis was that more patients receiving BEV-CT than CT would achieve at least a 15% (≥ 15-point) absolute improvement on the QLQ-OV28 abdominal/GI symptom subscale (items 31-36) at week 8/9. Patients with missing week 8/9 questionnaires were included as unimproved. Questionnaires from all assessments until disease progression were analyzed using mixed-model repeated-measures (MMRM) analysis. Sensitivity analyses were used to determine the effects of differing assumptions and methods for missing data. RESULTS Baseline questionnaires were available from 89% of 361 randomly assigned patients. More BEV-CT than CT patients achieved a ≥ 15% improvement in abdominal/GI symptoms at week 8/9 (primary PRO end point, 21.9% v 9.3%; difference, 12.7%; 95% CI, 4.4 to 20.9; P = .002). MMRM analysis covering all time points also favored BEV-CT (difference, 6.4 points; 95% CI, 1.3 to 11.6; P = .015). More BEV-CT than CT patients achieved ≥ 15% improvement in FOSI at week 8/9 (12.2% v 3.1%; difference, 9.0%; 95% CI, 2.9% to 15.2%; P = .003). Sensitivity analyses gave similar results and conclusions. CONCLUSION Bevacizumab increased the proportion of patients achieving a 15% improvement in patient-reported abdominal/GI symptoms during chemotherapy for platinum-resistant ovarian cancer.

Health-related quality of life and sequelae in patients treated with brachytherapy and external beam irradiation for localized prostate cancer

PURPOSE To evaluate late physical and psychosocial sequelae in patients treated with an association of external beam irradiation (EBI) and brachytherapy (BT) for localized prostate cancer. PATIENTS AND METHODS Seventy-one patients free of disease, treated at the Centre François Baclesse from 1988 to 1992, were enrolled in a case-control study. Seventy-one healthy controls, matched on age and residence, were selected at random from electoral rolls. Two self-administered questionnaires were mailed in January 1996. The French translation of the Nottingham Health Profile questionnaire and the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 core questionnaire were used to evaluate physical, role, emotional, cognitive and social functioning, global health status as well as energy and sleep disturbance. Specific problems related to prostate cancer were explored using the prostate specific module developed by the EORTC Genito-Urinary Tract Cancer Cooperative Group. Concordance between clinical complications reported by patients and those reported by physicians was also analyzed. RESULTS General health quality of life scale scores did not significantly differ between patients and controls, nor did general symptom scale scores. Furthermore, no more late psychosocial sequelae were reported by patients than by controls. No major digestive complications were observed among patients. However, statistical differences were observed concerning interest in sex (P = 0.016) and sexual activity (P < 0.001), urinary incontinence (P < 0.001) and cystitis (P = 0.01). Late subjective morbidity (dysuria, nocturia, urinary incontinence, pelvic pain) appraisal differed slightly between patients and physicians who generally underestimate its severity. While nocturia was reported more often by physicians than by patients (P = 0.0016), patients reported urinary incontinence and pelvic pain more often than physicians (P < 0.001 and P < 0.001, respectively). CONCLUSIONS The study demonstrates that survivors from localized prostate cancer treated with an association of BT and EBI have good global health status. Major problems that persist are sexual disorders, urinary incontinence and cystitis while digestive disorders were rare. This association could be an alternative to standard EBI in patients with localized prostate cancer. Whatever the treatment choice, patients should be involved in the therapeutic decision which should consider not only expected survival rate but also quality of life.

Docetaxel-Based Chemotherapy in Elderly Patients (Age 75 and Older) with Castration-Resistant Prostate Cancer

BACKGROUND There are no data on the patterns of care and outcome of very elderly patients with castration-resistant prostate cancer (CRPC) treated with docetaxel. OBJECTIVE To assess the routine use of first-line docetaxel-based chemotherapy in CRPC patients aged >75 yr. DESIGN, SETTING, AND PARTICIPANTS We reviewed the clinical files of 175 patients aged > or =75 yr with CRPC treated with first-line docetaxel in nine French tertiary care cancer centres from 2000 to 2007. MEASUREMENTS Response rate, survival, and adverse events (AE). RESULTS AND LIMITATIONS Median age was 78 yr. Ninety-five patients (54%) received a standard 3-wk regimen (SR), and 80 patients (46%) received an adapted regimen (AR) delivered on a weekly schedule with various times for rest periods. Patients treated with an AR were older (>80 yr) and had poorer performance status (PS; > or =2) than patients treated with the SR. The prostate-specific antigen (PSA) response rates were not significantly different between the standard and adapted treatment groups (71% vs 68%, p=0.79). The median progression-free survival (PFS) was 7.4 mo. The median overall survival (OS) was 15 mo. The incidence of grade 3 or 4 AEs was 46% and was correlated with poor PS and the presence of visceral disease but not with the regimen. Early discontinuation of treatment because of toxicity occurred more frequently in the AR group than in the SR group (30% vs 8.4%, p=0.0005). In multivariate analysis, only PS and the presence of visceral disease were predictors of OS. CONCLUSIONS Docetaxel is active and feasible in elderly patients with good PS. The optimal treatment of frail patients with CRPC remains to be established. Geriatric tools should be used to more accurately detect elderly CRPC patients who are unfit for chemotherapy. Age by itself should not be used as a criterion to deny patients with CRPC a potentially effective chemotherapy.
