Predictive value of health-related quality of life on radiotherapy-related toxicities in patients with head and neck cancer.

PURPOSE: Little is known about whether baseline health-related quality of life (HRQoL) scores also could predict occurrence radiotherapy-related toxicities, which we aim to assess in this study. METHODS: This study analyzed data from 200 patients enrolled in randomized study investigating the utility of HRQoL. HRQOL was assessed at baseline and during follow up using QLQ-C30 questionnaire and major toxicity was considered as adverse event ≥ 3 according to NCI-CTCAE classification. Cox regressions adjusting for clinical and sociodemographic data were used to assess prognostic significance of HRQOL scores. RESULTS: In multivariable analyses adjusted on clinical and sociodemographic data, every 10-point improvement in physical (HR = 0.74), role (HR = 0.87) and social (HR = 0.88) functioning was associated with 24%, 13% and 12% lower hazard of occurrence of major toxicity respectively while every 10 point-increase in dyspnea (HR = and loss appetite was associated with 15% and 16% increased hazard of major toxicity. CONCLUSION: Certain baseline HRQoL scores were found to be significantly associated with the occurrence of major toxicity.

Randomized Trial Assessing the Impact of Routine Assessment of Health-Related Quality of Life in Patients with Head and Neck Cancer.

The impact of routine assessment of health-related quality of life (HRQoL) on satisfaction with care and the HRQoL of patients with head and neck cancer (HNC) treated with radiotherapy was assessed. Patients with HNC were randomly assigned to two arms, with stratification on sex, cancer localization, and stage of the disease. In the intervention arm, the patients completed the EORTC QLQ-C30 and EORTC QLQ-H&N35 questionnaires first before randomization, then before each medical appointment during radiotherapy (7 weeks), and then every 3 months until 1 year and at 2 years thereafter. In the control arm, the EORTC QLQ-C30 and EORTC QLQ-H&N35 questionnaires were completed before randomization and at 1 year and 2 years thereafter. The primary endpoint was mean change in HRQoL at score at 2 years from baseline assessed by EQ VAS from the EuroQol questionnaire. The secondary endpoint was mean change in satisfaction with care at 2 years from baseline assessed by QLQ-SAT32. Two hundred patients with head and neck cancers were involved in this study (mean age, 58.83 years (range, 36.56-87.89)), of whom 100 were assigned to the intervention arm and 100 to the control arm. Patients in the intervention arm were reported to have a statistically significant increase in EQ VAS at 2 years (p < 0.0001) and exceeded the minimal clinically important difference (mean change at 2 years from baseline = 10.46). In the two arms, mean differences between arms were not statistically significant, but minimal clinically important differences in favor of the intervention arm were found for EQ VAS (mean change difference (MD) = 5.84), satisfaction with care, in particular waiting times (MD = 10.85) and satisfaction with accessibility (MD = 6.52). Routine assessment of HRQoL improves HRQoL and satisfaction with care for patients with HNC treated with radiotherapy.

Chemotherapy use in end-of-life digestive cancer patients: a retrospective AGEO observational study.

BACKGROUND: The use of chemotherapy (CT) near the end-of-life (EOL) is an important issue in oncology since it could degrade quality of life. CT near EOL is still poorly studied, with no dedicated study in gastrointestinal (GI) cancer patients. AIM: To analyze in GI cancer patients the factors associated with the use of CT within 3- and 1-month before patients' death. METHODS AND PARTICIPANTS: All consecutive patients who died from a GI cancer in 10 French tertiary care hospitals during 2014 were included in this retrospective study. Clinical, demographical and biological data were collected and compared between patients receiving or not CT within 3- and 1-month before death. Variables associated with overall survival (OS) was also determined using of univariate and multivariate analyses with a Cox model. RESULTS: Four hundred and thirty-seven patients with a metastatic GI cancer were included in this study. Among them, 293 pts (67.0%) received CT within 3-months before death, and 121 pts (27.7%) received CT within 1-month before death. Patients receiving CT within 3-months before death were significantly younger (median age: 65.5 vs 72.8 years, p < 0.0001), with a better PS (PS 0 or 1: 53.9 vs 29.3%, p < 0.0001) and a higher albumin level (median: 32.8 vs 31.0 g/L, p = 0.048). Similar results were found for CT within 1 month before death. Palliative care team intervention was less frequent in patients who received CT in their last month of life (39.7% vs 51.3%, p = 0.02). In multivariate analysis, median OS from diagnosis was shorter in the group receiving CT within 1-month before death (HR = 0.59; 95% CI [0.48-0.74]). CONCLUSION: In GI-cancer patients, CT is administered within 3- and 1-month before death, in two and one third of patients, respectively. Patients receiving CT within 1-month before death, had more aggressive disease with poor OS. Palliative care team intervention was associated with less administration of CT in the last month of life. These results highlight the need to better anticipate the time to stop CT treatment in the end-of-life and the importance of an active collaboration between oncology and palliative care teams.

Predictive Value of Neutrophils Count for Local Tumor Control After Chemoradiotherapy in Patients With Locally Advanced Pancreatic Carcinoma.

PURPOSE: Baseline neutrophil count may predict overall survival (OS) in patients with locally advanced pancreatic cancer (LAPC). METHODS AND MATERIALS: The international multicenter randomized LAP07 phase 3 trial has enrolled 442 patients with LAPC. We analyzed the prognostic value of both baseline neutrophilia (neutrophil count >7 g/L) and elevated or increasing neutrophil count as (1) neutrophilia or (2) increased absolute neutrophil count after induction chemotherapy versus baseline for OS, progression-free survival, and local control (LC). A Cox proportional hazard model was used to assess elevated or increasing neutrophil count status by randomly assigned treatment interactions for each endpoint. RESULTS: Among the 442 patients, 47 patients (11%) with baseline neutrophilia had worse OS (median 8.9 vs 13.3 months; P = .01). After induction chemotherapy, among the 235 patients whose blood counts were available, 90 patients (38%) had elevated or increasing neutrophil count associated with poorer OS in univariate (median 14.4 vs 17.9 months; P = .001) and multivariate analysis (P = .004). Elevated or increasing neutrophil count was also predictive of a decreased benefit of chemoradiation therapy on LC. In 126 patients without elevated or increasing neutrophil count, 1-year LC was 80% in the chemoradiation arm versus 54% in the chemotherapy arm (P < .001; interaction test P = .015). CONCLUSIONS: In this study, baseline neutrophilia and increased absolute neutrophil count were associated with worse OS in this large series of patients with LAPC. In addition, the counts were an independent prognosis factor and a strong predictive LC biomarker for chemoradiation therapy benefit. An assessment of neutrophils counts can help to improve the selection of patients who might benefit from chemoradiation therapy after induction chemotherapy.

Longitudinal analysis of health-related quality of life in cancer clinical trials: methods and interpretation of results.

PURPOSE: Health-related quality of life (HRQoL) is assessed by self-administered questionnaires throughout the care process. Classically, two longitudinal statistical approaches were mainly used to study HRQoL: linear mixed models (LMM) or time-to-event models for time to deterioration/time until definitive deterioration (TTD/TUDD). Recently, an alternative strategy based on generalized linear mixed models for categorical data has also been proposed: the longitudinal partial credit model (LPCM). The objective of this article is to evaluate these methods and to propose recommendations to standardize longitudinal analysis of HRQoL data in cancer clinical trials. METHODS: The three methods are first described and compared through statistical, methodological, and practical arguments, then applied on real HRQoL data from clinical cancer trials or published prospective databases. In total, seven French studies from a collaborating group were selected with longitudinal collection of QLQ-C30. Longitudinal analyses were performed with the three approaches using SAS, Stata and R software. RESULTS: We observed concordant results between LMM and LPCM. However, discordant results were observed when we considered the TTD/TUDD approach compared to the two previous methods. According to methodological and practical arguments discussed, the approaches seem to provide additional information and complementary interpretations. LMM and LPCM are the most powerful methods on simulated data, while the TTD/TUDD approach gives more clinically understandable results. Finally, for single-item scales, LPCM is more appropriate. CONCLUSION: These results pledge for the recommendation to use of both the LMM and TTD/TUDD longitudinal methods, except for single-item scales, establishing them as the consensual methods for publications reporting HRQoL.

Guidelines for time-to-event end-point definitions in adjuvant randomised trials for patients with localised colon cancer: Results of the DATECAN initiative.

BACKGROUND: The variability of definitions for time-to-event (TTE) end-points impacts the conclusions of randomised clinical trials (RCTs). The Definition for the Assessment of Time-to-event Endpoints in CANcer (DATECAN) initiative aims to provide consensus definitions for TTE end-points used in RCTs. Here, we formulate guidelines for adjuvant colon cancer RCTs. METHODS: We performed a literature review to identify TTE end-points and events included in their definition in RCT publications. Then, a consensus was reached among a panel of international experts, using a formal modified Delphi method, with 2 rounds of questionnaires and an in-person meeting. RESULTS: Twenty-four experts scored 72 events involved in 6 TTE end-points. Consensus was reached for 24%, 57% and 100% events after the first round, second round and in-person meeting. For RCTs not using overall survival as their primary end-point, the experts recommend using disease-free survival (DFS) rather than recurrence-free survival (RFS) or time to recurrence (TTR) as the primary end-point. The consensus definition of DFS includes all causes of death, second primary colorectal cancers (CRCs), anastomotic relapse and metastatic relapse as an event, but not second primary non-CRCs. Events included in the RFS definition are the same as for DFS with the exception of second primary CRCs. The consensus definition of TTR includes anastomotic or metastatic relapse, death with evidence of recurrence and death from CC cause. CONCLUSION: Standardised definitions of TTE end-points ensure the reproducibility of the end-points between RCTs and facilitate cross-trial comparisons. These definitions should be integrated in standard practice for the design, reporting and interpretation of adjuvant CC RCTs.

Health-related Quality of Life Following Hybrid Minimally Invasive Versus Open Esophagectomy for Patients With Esophageal Cancer, Analysis of a Multicenter, Open-label, Randomized Phase III Controlled Trial: The MIRO Trial.

BACKGROUND: Hybrid minimally invasive esophagectomy (HMIE) has been shown to reduce major postoperative complications compared with open esophagectomy (OE) for esophageal cancer. OBJECTIVES: The aim of this study was to compare short- and long-term health-related quality of life (HRQOL) following HMIE and OE within a randomized controlled trial. METHODS: We performed a multicenter, open-label, randomized controlled trial at 13 study centers between 2009 and 2012. Patients aged 18 to 75 years with resectable cancers of the middle or lower third of the esophagus were randomized to undergo either transthoracic OE or HMIE. Patients were followed-up every 6 months for 3 years postoperatively and global health assessed with EORTC-QLQC30 and esophageal symptoms assessed with EORTC-OES18. RESULTS: The short-term reduction in global HRQOL at 30 days specifically role functioning [-33.33 (HMIE) vs -46.3 (OE); P = 0.0407] and social functioning [-16.88 (HMIE) vs -35.74 (OE); P = 0.0003] was less substantial in the HMIE group. At 2 years, social functioning had improved following HMIE to beyond baseline (+5.37) but remained reduced in the OE group (-8.33) (P = 0.0303). At 2 years, increases in pain were similarly reduced in the HMIE compared with the OE group [+6.94 (HMIE) vs +14.05 (OE); P = 0.018]. Postoperative complications in multivariate analysis were associated with role functioning, pain, and dysphagia. CONCLUSIONS: Esophagectomy has substantial effects upon short-term HRQOL. These effects for some specific parameters are, however, reduced with HMIE, with persistent differences up to 2 years, and maybe mediated by a reduction in postoperative complications.

Impact on health-related quality of life deterioration-free survival of a first-line therapy combining nab-paclitaxel plus either gemcitabine or simplified leucovorin and fluorouracil for patients with metastatic pancreatic cancer: Results of the randomized phase II AFUGEM GERCOR clinical trial.

BACKGROUND: The phase II AFUGEM GERCOR trial aimed to assess the efficacy of a first-line therapy combining nab-paclitaxel plus either gemcitabine (gemcitabine group) or simplified leucovorin and fluorouracil (sLV5FU2 group) in patients with previously untreated metastatic pancreatic cancer. Results of progression-free survival at 4 months (primary endpoint) were in favor of the sLV5FU2 group. This paper presents health-related quality of life (HRQoL) data as a secondary endpoint. METHODS: HRQoL was assessed using the EORTC QLQ-C30 questionnaire at baseline and at each chemotherapy cycle until the end of treatment. The HRQoL deterioration-free survival (QFS) was used as a modality of longitudinal analysis. QFS was defined as the time between randomization and the first definitive HRQoL score deterioration as compared to the baseline score, or death. Sensitivity analysis was performed excluding death as an event. Univariate Cox models were used to estimate hazard ratios (HRs) and 90% confidence intervals (CIs) of the treatment effect. RESULTS: Between 2013 and 2014, 114 patients were randomized in a 1:2 ratio (39 in the gemcitabine group and 75 in the sLV5FU2 group). Patients in the sLV5FU2 group seemed to present longer QFS than those of the gemcitabine group for 14 out of 15 dimensions, with HRs < 1. Results of the sensitivity analysis excluding death as an event were significantly in favor of the sLV5FU2 group for physical functioning (HR = 0.51 [90% CI 0.27-0.97]) and pain (HR = 0.26 [90% CI 0.09-0.74]). CONCLUSION: The nab-paclitaxel plus simplified leucovorin and fluorouracil combination had no negative impact in exploratory HRQoL analyses.

Effectiveness assessment of riluzole in the prevention of oxaliplatin-induced peripheral neuropathy: RILUZOX-01: protocol of a randomised, parallel, controlled, double-blind and multicentre study by the UNICANCER-AFSOS Supportive Care intergroup.

INTRODUCTION: Most patients (>70%) experience acute neuropathic symptoms shortly after oxaliplatin infusions. These symptoms are not always resolved between infusions. Overall, 30%-50% of patients suffer from chronic oxaliplatin-induced peripheral neuropathy (OIPN). This cumulative and dose-dependent sensory neuropathy limits compliance or results in oxaliplatin-based chemotherapies to be substituted with less neurotoxic agents. These treatment changes impair clinical outcomes, and may be associated with comorbidities, such as distress, depression and anxiety. Currently, no drug used to prevent or treat OIPN is sufficiently effective to be used routinely in clinical practice. There is, thus, an unmet therapeutic need to reduce the intensity of and/or prevent OIPN. We hypothesised that riluzole would be an excellent candidate to address this public health issue. Riluzole is approved for treating amyotrophic lateral sclerosis. In animals, there is a beneficial effect on sensorimotor and pain disorders, as well as related comorbidities, after repeated administration of oxaliplatin. In humans, riluzole has shown neuroprotective, anxiolytic and antidepressive effects. METHODS AND ANALYSIS: RILUZOX-01 trial was designed as a randomised, controlled, double-blind study to evaluate the efficacy of riluzole to prevent OIPN. Patients with colorectal cancer and initiating adjuvant oxaliplatin-based chemotherapy are eligible. Patients (n=210) will be randomly assigned to either riluzole or placebo, concomitantly with chemotherapy. The primary endpoint is the change in OIPN intensity, assessed by the sensory scale of the QLQ-CIPN20, after six 2-week cycles of chemotherapy. Secondary endpoints include incidence and severity of neuropathy, grade of sensory neuropathy, intensity and features of neuropathic pain, health-related quality of life, disease-free survival, overall survival and safety. ETHICS AND DESSIMINATION: The study was approved by a French ethics committee (ref:39/18_1, 'Comité de Protection des Personnes' Ouest-IV, France) and plans to start enroling patients in September 2019. The trial is registered in EudraCT and clinicaltrials.gov. TRIAL REGISTRATION NUMBER: N°2017-002320-25; NCT03722680.

Staging of nutrition disorders in non-small-cell lung cancer patients: utility of skeletal muscle mass assessment.

BACKGROUND: An international consensus proposed in 2011 a definition and classification system for cachexia (CAX), mainly based on weight loss, sarcopenia [skeletal muscle mass (SMM) loss], inflammation, and anorexia. The aim of this study was to stage CAX in non-small-cell lung cancer (NSCLC) patients by using a classification based on the Fearon criteria and supported by quantifiable parameters. METHODS: This was a cross-sectional and non-interventional multicentre study. SMM was assessed by analysing L3 computed tomography-scan images. Patients completed the anorexia/CAX subscale of the Functional Assessment of Anorexia/Cachexia Therapy, EORTC QLQ-C30 quality of life (QoL) and International Physical Activity Questionnaire (IPAQ). RESULTS: Patients were recruited in 56 sites. The analysis population comprised 531 patients, and SMM was assessed in 312 patients. Male patients were 66.5%, with a mean (SD) age of 65.2 (10.0) years, 79.9% were PS 0-1, and the tumour stage was mainly IIIB-IV (87.3%). Overall, 38.7% of patients had CAX, 33.8% pre-CAX, and 0.9% refractory CAX. Molecular tumour profiles were significantly associated with the presence of CAX: 23.9% in EGFR, ALK, ROS1, BRAF, or HER2+ patients, 41.4% in K-RAS+, and 43.2% in patients with no molecular abnormality (P = 0.003). The more advanced the CAX stage, the poorer the scores of functional items of the QoL (P < 0.001) and International Physical Activity Questionnaire (P < 0.001). Sarcopenia was present in 66.7% of CAX and 68.5% of pre-CAX patients. Overall, 43.8% of pre-CAX patients had only sarcopenia with limited weight loss (≤2%) and no anorexia. CONCLUSIONS: This is the first study to show the distribution of CAX in a population of NSCLC patients and an association between molecular abnormality in NSCLC and CAX. The original Fearon classification for CAX stages was supported by the associated functional QoL scores and physical activity levels, resulting in a clinically relevant system for detection of early stages of CAX.

Health-related quality of life as an endpoint in oncology phase I trials: a systematic review.

BACKGROUND: Phase I trials aim to identify the recommended dose for further development. Health-related quality of life (HRQoL) could be a complement to the usual National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) scale to detect adverse events and define the doses. The objective of this study is to review the phase I in oncology which used HRQoL as endpoint. METHODS: A search in PubMed database identified phase I trials in oncology with HRQoL as endpoint, published between January 2012 to May 2016. Hematological and pediatric phase I were excluded. RESULTS: A total of 1333 phase I were identified and 15 trials were identified with HRQoL as endpoint (1.1%). The European Organisation for Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) was the most frequently used instrument: 5 studies (33.3%). The targeted dimensions of HRQoL and the minimal clinically important difference were prespecified in 1 study (6.7%) and 2 studies (13.3%), respectively. Twelve studies (80%) described the statistical approach to analyze HRQoL data. Eight studies used the mean change from baseline (60%) to analyse longitudinal HRQoL data, two the mean score at certain times (13.3%), one the linear mixed model for repeated measures (6.7%), one the time to HRQoL score deterioration (6.7%), one percentage of patient-reported symptoms (6.7%). None of the studies used HRQoL to determine the recommended doses. CONCLUSION: Few phase I studies used HRQoL as endpoint and among studies with HRQoL as endpoint, the methodology of HRQoL measurement and statistical analysis was heterogeneous. HRQoL. endpoint not used for assessing the recommended phase II doses.

Propensity score methods and regression adjustment for analysis of nonrandomized studies with health-related quality of life outcomes.

PURPOSE: The aim of this study was to investigate the potential added value of combining propensity score (PS) methods with multivariable linear regression (MLR) in estimating the average treatment effect on the treated (ATT) in nonrandomized studies with health-related quality of life (HRQoL) outcomes. METHODS: We first used simulations to compare the performances of different PS-based methods, either alone or in combination with further MLR adjustment, in estimating ATT. PS methods were, respectively, optimal pair (OPM) and full (OFM) PS matching, subclassification on the PS (SBC), and the inverse probability of treatment weighting (IPTW). We simulated several scenarios, according to different sample sizes, proportions of treated vs untreated subjects, and types of HRQoL outcomes. We also applied the same methods to a real clinical data set. RESULTS: OPM and IPTW provided the closest Type I error to the nominal threshold α = 0.05 across all scenarios. Overall, both methods showed also lower variability in estimates than SBC and OFM. SBC performed worst, generally providing the highest levels of bias. Further MLR adjustment lessened bias for all methods, however providing higher Type I error for SBC and OFM. In the real case, all methods provided similar ATT estimates except for one outcome. CONCLUSIONS: Our findings suggest that for sample sizes up to n = 200, OPM and IPTW are to be preferred to OFM and SBC in estimating ATT on HRQoL outcomes. Specifically, OPM performed best in sample sizes of n ≥ 80, IPTW for smaller sample sizes. Additional MLR adjustment can further improve ATT estimates.

The role of trait emotional intelligence in quality of life, anxiety and depression symptoms after surgery for esophageal or gastric cancer: A French national database FREGAT.

OBJECTIVE: The main objective was to test the indirect effects of emotional competence (EC) after diagnosis (T1) on the health-related quality of life (HRQoL) after surgery (T2) of esogastric cancer patients via fewer anxiety and depression symptoms (T2). METHODS: Data were collected from 30 French centers via the clinicobiological database French EsoGastric Tumors (FREGAT). Two hundred and twenty-eight participants completed a self-reported questionnaire at T1 and T2, assessing their EC (Profile of Emotional Competence (PEC)), HRQoL (EORTC Quality of Life Questionnaire-Core (QLQ-C30)), and anxiety and depression symptoms (Hospital Anxiety and Depression Scale (HADS)). Regression analyses were used to test the direct effects of intrapersonal and interpersonal EC on their anxiety/depression symptoms and HRQoL at T1 and T2. The PROCESS Macro in SPPS v.22 with bootstrap methods was used to test the indirect effects of intrapersonal and interpersonal EC at T1 on HRQoL at T2 via anxiety and depression symptoms. RESULTS: EC predicted fewer anxiety and depression symptoms of patients at T1 and T2 and better HRQoL at T1. EC at T1 also predicted a better HRQoL at T2 via fewer anxiety and depression symptoms at T2. CONCLUSIONS: Patients who tended to use their EC in daily life could be more effective in regulating the emotional impact of the cancer diagnosis and surgery. This explains why they reported fewer anxiety and depression symptoms, which in turn enabled a better perceived HRQoL after surgery. Therefore, reinforcing the use of patients' EC in daily life following their diagnosis could decrease their emotional distress and, in this way, improve their HRQoL in the preoperative and postoperative stages.

Health-related quality of life assessment for patients with advanced or metastatic renal cell carcinoma treated with a tyrosine kinase inhibitor using electronic patient-reported outcomes in daily clinical practice (QUANARIE trial): study protocol.

BACKGROUND: Two main therapies, pazopanib and sunitinib, are used in the first-line setting for metastatic renal cell carcinoma (mRCC). These two tyrosine kinase inhibitors (TKI) are equally effective in terms of survival; however, they frequently induce adverse events. In this setting, Health-Related Quality of life (HRQoL) is a key element in the choice between these two treatments and the evaluation of treatment effectiveness. It could be of interest to evaluate HRQoL in daily clinical practice to aid adequate therapy choice and management. Currently, the development of information and communication technology may allow HRQoL monitoring in routine practice. The objective of the QUANARIE study is to evaluate the use of HRQoL assessment in daily clinical practice for patients with mRCC treated with TKI using electronic patient-reported outcomes (e-PRO). The present article describes the key elements of the study protocol. METHODS: The QUANARIE study is an interventional, prospective, multicentre trial. Patients diagnosed with mRCC initiating sunitinib or pazopanib treatment will be invited to complete the EORTC QLQ-C30 questionnaire, nine additional questions from the EORTC items library, and the EuroQoL EQ-5D, prior to each visit with the physician. Questionnaires will be completed by patients using tablets and/or computer terminals via the e-PRO software. The physician will have real-time access to a visual summary of the HRQoL evaluation. The primary objective is to assess the proportion of patients having good compliance with Routine Electronic Monitoring of HRQoL (REMOQOL) during the first 12 months. Physicians' satisfaction with REMOQOL will be assessed as a secondary objective. We hypothesise that 80% of patients having good compliance with REMOQOL would be meaningful. A sample size of 56 patients would be needed. DISCUSSION: The results of this study will show whether REMOQOL is feasible on a large scale and whether patients are receptive to this new practice. This study will also determine how real-time multidimensional evaluation of patient perception can help physicians in their daily practice and how they used it in conjunction with other clinical information to manage patient care.

Efficacy of aflibercept with FOLFOX and maintenance with fluoropyrimidine as first­line therapy for metastatic colorectal cancer: GERCOR VELVET phase II study.

Aflibercept in combination with 5­fluorouracil (5­FU)/irinotecan improves overall survival in the second­line therapy of patients with metastatic colorectal cancer (mCRC). In this study, we evaluated the effects of aflibercept in first­line therapy with FOLFOX followed by maintenance with fluoropyrimidine. VELVET was a prospective, single­arm multicenter phase II study (completed). Patients with previously untreated, unresectable, evaluable or measurable mCRC, with an age ≥18 years, and an ECOG performance status of 0­2 received 6 cycles of modified FOLFOX7 (5­FU/folinic acid and oxaliplatin) with aflibercept at 4 mg/kg every 2 weeks followed by maintenance therapy with fluoropyrimidine with aflibercept until disease progression or limiting toxicity. The reintroduction of oxaliplatin was performed at first progression. The primary endpoint was progression­free survival (PFS) at 6 months. From May, 2013 to May, 2014, 49 patients were included and 48 were evaluable for response. In total, 33 patients (67.4%) were alive without progression at 6 months. The Kaplan­Meier survival 6­month and 1­year PFS rates were 79.1 and 36.1%, respectively, and the median PFS was 9.3 months (95% CI, 8.3­12.5). The objective response rate was 59.2% (N=29/49). The most common (≥10%) grade 3­4 adverse events were hypertension (23%), fatigue (15%), neutropenia (12%), neuropathy (12%) and stomatitis (10%). Three (6%) treatment­related deaths occurred: One from stroke, one from pulmonary embolism and one from neutropenic sepsis. On the whole, this study demonstrates the efficacy of aflibercept in combination with an oxaliplatin­based regimen in the first­line therapy of patients with mCRC. A strict monitoring of blood pressure and immediate management of hypertension during therapy is mandatory.

Modeling strategies to improve parameter estimates in prognostic factors analyses with patient-reported outcomes in oncology.

PURPOSE: The inclusion of patient-reported outcome (PRO) questionnaires in prognostic factor analyses in oncology has substantially increased in recent years. We performed a simulation study to compare the performances of four different modeling strategies in estimating the prognostic impact of multiple collinear scales from PRO questionnaires. METHODS: We generated multiple scenarios describing survival data with different sample sizes, event rates and degrees of multicollinearity among five PRO scales. We used the Cox proportional hazards (PH) model to estimate the hazard ratios (HR) using automatic selection procedures, which were based on either the likelihood ratio-test (Cox-PV) or the Akaike Information Criterion (Cox-AIC). We also used Cox PH models which included all variables and were either penalized using the Ridge regression (Cox-R) or were estimated as usual (Cox-Full). For each scenario, we simulated 1000 independent datasets and compared the average outcomes of all methods. RESULTS: The Cox-R showed similar or better performances with respect to the other methods, particularly in scenarios with medium-high multicollinearity (ρ = 0.4 to ρ = 0.8) and small sample sizes (n = 100). Overall, the Cox-PV and Cox-AIC performed worse, for example they did not select one or more prognostic collinear PRO scales in some scenarios. Compared with the Cox-Full, the Cox-R provided HR estimates with similar bias patterns but smaller root-mean-squared errors, particularly in higher multicollinearity scenarios. CONCLUSIONS: Our findings suggest that the Cox-R is the best approach when performing prognostic factor analyses with multiple and collinear PRO scales, particularly in situations of high multicollinearity, small sample sizes and low event rates.

Hybrid Minimally Invasive Esophagectomy for Esophageal Cancer.

BACKGROUND: Postoperative complications, especially pulmonary complications, affect more than half the patients who undergo open esophagectomy for esophageal cancer. Whether hybrid minimally invasive esophagectomy results in lower morbidity than open esophagectomy is unclear. METHODS: We performed a multicenter, open-label, randomized, controlled trial involving patients 18 to 75 years of age with resectable cancer of the middle or lower third of the esophagus. Patients were randomly assigned to undergo transthoracic open esophagectomy (open procedure) or hybrid minimally invasive esophagectomy (hybrid procedure). Surgical quality assurance was implemented by the credentialing of surgeons, standardization of technique, and monitoring of performance. Hybrid surgery comprised a two-field abdominal-thoracic operation (also called an Ivor-Lewis procedure) with laparoscopic gastric mobilization and open right thoracotomy. The primary end point was intraoperative or postoperative complication of grade II or higher according to the Clavien-Dindo classification (indicating major complication leading to intervention) within 30 days. Analyses were done according to the intention-to-treat principle. RESULTS: From October 2009 through April 2012, we randomly assigned 103 patients to the hybrid-procedure group and 104 to the open-procedure group. A total of 312 serious adverse events were recorded in 110 patients. A total of 37 patients (36%) in the hybrid-procedure group had a major intraoperative or postoperative complication, as compared with 67 (64%) in the open-procedure group (odds ratio, 0.31; 95% confidence interval [CI], 0.18 to 0.55; P<0.001). A total of 18 of 102 patients (18%) in the hybrid-procedure group had a major pulmonary complication, as compared with 31 of 103 (30%) in the open-procedure group. At 3 years, overall survival was 67% (95% CI, 57 to 75) in the hybrid-procedure group, as compared with 55% (95% CI, 45 to 64) in the open-procedure group; disease-free survival was 57% (95% CI, 47 to 66) and 48% (95% CI, 38 to 57), respectively. CONCLUSIONS: We found that hybrid minimally invasive esophagectomy resulted in a lower incidence of intraoperative and postoperative major complications, specifically pulmonary complications, than open esophagectomy, without compromising overall and disease-free survival over a period of 3 years.

Psychometric validation of the French version of the Supportive Care Needs Survey for Partners and Caregivers of cancer patients.

The objective of this study was to assess the psychometric properties of the French version of the Supportive Care Needs Survey for Partners and Caregivers (SCNS-P&C-F). The SCNS-P&C-F, the Hospital Anxiety and Depression Scale (HADS) and the CareGiver Oncology Quality of Life questionnaire (CarGOQoL) were completed by 327 caregivers at the baseline. The SCNS-P&C-F was completed a second time by 121 participants within 30 days. Four factors were retained with a good explanation of variance (82.65%) and acceptable internal consistencies (α: 0.70 to 0.94): 1) Health Care Service and Information Needs, 2) Emotional and Psychological Needs, 3) Work and Social Security Needs and 4) Communication and Family Support Needs. Overall, convergent and divergent validities were confirmed. The caregiver's gender, age, professional status and level of anxiety and depression, as well as the type of relationship with the patient and cancer, showed an effect on some caregivers' unmet supportive care needs. Lastly, the test-retest reliability was acceptable (> 0.70), except for the communication and family support dimension. The scale is appropriate for clinical and research use (e.g. good reliability and validity).

Switch from abiraterone plus prednisone to abiraterone plus dexamethasone at asymptomatic PSA progression in patients with metastatic castration-resistant prostate cancer.

OBJECTIVE: To evaluate the effects of switching from prednisone (P) to dexamethasone (D) at asymptomatic prostate-specific antigen (PSA) progression in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with abiraterone acetate (AA). MATERIALS AND METHODS: Among 93 patients treated with AA between January 2013 and April 2016 in our institution, 48 consecutive asymptomatic patients with mCRPC, who experienced biochemical progression on treatment with AA+P 10 mg/day, were included. A corticosteroid switch to AA+D 0.5 mg/day at PSA increase was administered until radiological and/or clinical progression. The primary endpoint was progression-free-survival (PFS). A prognostic score based on independent prognostic factors was defined. RESULTS: The median time to PSA progression on AA+P was 8.94 months. The median PFS on AA+D and AA+corticosteroids (P then D) was 10.35 and 20.07 months, respectively. A total of 56.25% of patients showed a decrease or stabilization in PSA levels after the switch. In univariate analysis, three markers of switch efficiency were significantly associated with a longer PFS: long hormone-sensitivity duration (≥5 years; median PFS 16.62 vs 4.17 months, hazard ratio [HR] 0.30, 90% confidence interval [CI] 0.16-0.56); low PSA level at the time of switch (<50 ng/mL; median PFS 15.21 vs 3.86 months, HR 0.33, 90% CI 0.18-0.60); and short time to PSA progression on AA+P (<6 months; median PFS 28.02 vs 6.65 months, HR 0.41 (90% CI 0.21-0.81). In multivariate analysis, hormone sensitivity duration and PSA level were independent prognostic factors. CONCLUSION: A steroid switch from P to D appears to be a safe and non-expensive way of obtaining long-term responses to AA in selected patients with mCRPC. A longer PFS has been observed in patients with previous long hormone sensitivity duration, and/or low PSA level and/or short time to PSA progression on AA+P.

Health-Related Quality of Life of Patients With Multiple Myeloma Treated in Routine Clinical Practice in France.

INTRODUCTION: New therapies for multiple myeloma (MM) have improved life expectancy, but health-related quality of life (HRQoL) data from patients with MM in the real-world setting are lacking. This study, conducted in France, explored the associations between treatment outcomes and HRQoL in patients with MM. PATIENTS AND METHODS: This observational, cross-sectional, multicenter study enrolled patients (≥ 18 years old) with symptomatic MM who had consulted a physician at least once between February and March 2016. HRQoL was assessed using the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life questionnaire (QLQ-C30) and the Quality of Life Multiple Myeloma module (QLQ-MY20). RESULTS: In total, 445 patients were included in the study; 402 (90%) completed the EORTC QLQ-C30 and QLQ-MY20 questionnaires. HRQoL decreased significantly with treatment line. Patients in the first treatment-free interval had relatively high scores. At later lines, patients receiving active treatment had better scores than those whose treatment had ended. High EORTC QLQ-C30 global health status scores were associated with good treatment response, few adverse events, and long duration of treatment, and were strongly influenced by the Eastern Cooperative Oncology Group performance status. Global health status scores correlated well with the 4 items of the QLQ-MY20 (future perspective, 0.46; body image, 0.41; disease symptoms, -0.57; side effects of treatment, -0.53). CONCLUSION: Effective treatment options in MM can help maintain HRQoL by influencing treatment response levels and delaying disease progression.
