Les critères de jugement centrés sur le patient dans les essais cliniques en oncologie thoracique

Overall survival (OS) is the gold standard endpoint in oncology clinical trials. Nevertheless, intermediate tumor-centered endpoints which are assessed earlier are more and more used as surrogate of OS. Health-related quality of life is an endpoint which assesses a direct benefit for the patient. We demonstrated that 32% of endpoints in advanced non-small-cell lung phase III clinical trials were not defined at all, 43% were not clearly defined and none ofthem has demonstrated its surrogacy on OS. We demonstrated the weakness and the heterogeneity of the measurement, analysis, and reporting of HRQoL in phase III advanced NSCLC trials. Precise and uniform recommendations are needed. We longitudinally compared HRQoL using tüne until definitive deterioration (TUDD) method in 451 patients aged 70-89 years with advanced NSCLC randomly assigned to receive a doublet of chemotherapy or a monochemotherapy. We demonstrated the benefit of the doublet chemotherapy in terms ofHRQoL. On a methodological point ofview TUDD method is feasible and provide clinically meaningful results. We proposed another approach which would be to combine intermediate endpoint• with HRQoL as co-primary endpoints. Finally, we demonstrated the additional prognostic value of HRQoL data at baseline to identify vulnerable subpopulations in elderly NSCLC patients.La Survie globale (SG) est le critère de jugement de référence dans les essais cliniques en oncologie mais les critères de jugement dit intennédiaires centrés sur la tumeur qui sont évalués plus précocement sont de plus en plus utilisés comme critères substitutifs de la survie globale La qualité de vie (QdV) constitue un critère de jugement pour évaluer un bénéfice clinique direct pour le patient. Nos résultats ont montré que 32% des critères de jugement dans les essais de phase III de CBNPC avancés étaient pas du tout définis et seulement 43% était clairement défini et qu'aucun critère intermédiaire n'a démontré sa substitutivité sur la SG. Nous avons montré que la mesure, l'analyse et le report des données de QdV étaient hétérogènes entre les essais de phase III de CBNPC avancés d'où la nécessité de recommandations. Nous avons comparé longitudinalement la QdV chez 451 patients âgés de 70-89 ans atteints de CBNPC avancés randomisés entre une bichimiothérapie et une monochimiothérapie selon la technique du temps jusqu'à détérioration définitive (TJD) d'un score de QdV. Cette étude a montré : sur le plan clinique, le bénéfice du doublet de chimiothérapie pour les patients est renforcé par les données de QdV; sur le plan méthodologique: le TJD est une technique d'analyse faisable dans les essais de phase III de CBNPC et fournit des résultats faciles d'interprétation. Nous avons proposé l'utilisation de co-critères de jugement principaux associant QdV et critère centré sur la tumeur. Enfin, nous avons démontré la valeur pronostique de la dimension santé globale de QdV à baseline du questionnaire sur la SG chez les patients âgés atteints de CBNPC avancés

Health-related quality of life analysis in ovarian cancer clinical trials involving PARP inhibitors: a critical methodological perspective

International audienceThe poly (ADP-ribose) polymerase inhibitors (PARPi) have yielded significant clinical benefits as maintenance therapy in women with newly diagnosed and relapsed platinum-sensitive advanced ovarian cancer. These drugs were approved based on progression-free survival, the primary endpoint of their respective pivotal trials. Health-related quality of life (HRQoL) and/or patient-reported outcomes were included in these trials as a secondary exploratory endpoint. Nevertheless, many weaknesses in the analysis of HRQoL across these trials can be noticed. Heterogeneity and suboptimal HRQoL analysis in oncology trials contribute to misconceptions about this endpoint among oncologists and prevent quality of life as being an endpoint used for approvals. In this article, we discuss these HRQoL results from a methodological perspective and propose some solutions for improvement that could be used by regulatory and academic institutions running ovarian cancers trials. Notably, we suggest to measure and analyze HRQoL data after disease progression, to focus dedicated papers on the statistical analyses of HRQoL recommended by the SISAQOL consortium (linear mixed model for repeated measures and time-to-event approaches) and to communicate on available guidelines to ensure compliance with best international practices regarding the measurement and analysis of HRQoL

Cancer-Related Alopecia: From Etiologies to Global Management

International audienceAlopecia represents a multifaceted challenge with distinct etiologies and consequences. Transposed to the world of oncology, different types of alopecia and molecular pathways have been characterized, allowing a better understanding of the underlying mechanisms. In patients with cancer, alopecia can be iatrogenic (i.e., due to conventional chemotherapies, endocrine therapies, targeted therapies, immunotherapies, radiotherapy and surgery) or a direct consequence of the disease itself (e.g., malnutrition, scalp metastases and paraneoplastic syndromes). Identification of the actual incriminated mechanism(s) is therefore essential in order to deliver appropriate supportive care, whether preventive or curative. On the preventive side, the last few years have seen the advent of the automated cooling cap, a prophylactic approach supported by several randomized clinical trials. On the curative side, although the treatments currently available are limited, several promising therapeutic approaches are under development. Appropriate alopecia management is essential, particularly regarding its psychological repercussions with significant consequences on the quality of life of patients and their family and with a potential impact on treatment compliance

Clinical Relevance of Routine Monitoring of Patient-reported Outcomes Versus Clinician-reported Outcomes in Oncology

International audienceThe National Cancer Institute Common Terminology Criteria for Adverse Events classification is the standard classification used by the physicians in oncology for reporting adverse events. This classification has evolved over the last years according to the emergence of new therapies. Reporting symptoms, quality of life (QoL) and toxicities via patient-reported outcomes (PROs) in clinical practice is not yet a standard of care, nevertheless many studies have been conducted recently to assess feasibility and impact of routine monitoring of PROs, which should enable for better management of toxicities and earlier detection of disease progression in a more patient-centered health care delivery system. The aim of this article was to discuss the advantages and limitations of both approaches, clinicians-reported outcomes and PROs. Growing evidence supports that the routine collection of PROs leads to improvement of QoL and overall survival of cancer patients

[Alopécie et cancers : de la physiopathologie à la pratique clinique]

International audienceAlopecia, although long considered an unavoidable consequence of cancer therapy, currently presents a multifaceted challenge. The knowledge of the physiology of the hair and consequently of the pathophysiology of alopecia has led to show that there is not one but several types of alopecia. Transposed to the world of oncology, different types of alopecia and subsequently molecular pathways have been characterized, allowing a better understanding of the underlying mechanisms. Thus, in patients with cancer, alopecia can be iatrogenic (chemotherapies, endocrine therapies, targeted therapies, immunotherapies, radiotherapy, surgery) or directly the consequence of the disease itself (malnutrition, scalp metastases, paraneoplastic syndromes). Knowledge of the incriminated mechanism(s) could thus make it possible to deploy an appropriate care component, whether on the preventive or curative sides or in terms of supportive care. These are particularly essential regarding the psychological repercussions caused by alopecia, with significant consequences on the quality of life of patients and with a potential impact on treatment compliance. On the preventive side, the last few years have seen the advent of the automated scalp cooling therapy, supported by several randomized clinical trials. On the curative side, several therapeutic proposals are currently deployed or under development in order to provide relevant treatments.L’alopécie, bien que longtemps considérée comme une conséquence inévitable de la thérapeutique anticancéreuse, représente actuellement un défi aux multiples facettes. La connaissance de la physiologie du cheveu et par voie de conséquence de la physiopathologie de l’alopécie a conduit à montrer qu’il n’y a pas une mais plusieurs types d’alopécies. Transposée au monde de l’oncologie, différents types d’alopécies et voies moléculaires impliquées ont pu être caractérisés, permettant de mieux comprendre les mécanismes à l’œuvre. Ainsi, chez des patients atteints de cancers, l’alopécie peut être iatrogène (chimiothérapies, hormonothérapies, thérapies ciblées, immunothérapies, radiothérapie, chirurgie) ou directement la conséquence de la maladie cancéreuse elle-même (dénutrition, métastases du scalp, syndromes paranéoplasiques). La connaissance du (ou des) mécanisme(s) incriminé(s) permet ainsi de mieux déployer un panel de soins appropriés, que ce soit sur les versants préventif et curatif ou encore en termes de soins de support. Ces derniers s’avèrent notamment essentiels en ce qui concerne le retentissement psychologique causé par l’alopécie, avec des conséquences non négligeables sur la qualité de vie des patients et sur l’observance thérapeutique. Sur le plan préventif, les dernières années ont vu l’avènement du casque réfrigérant automatisé, soutenu par plusieurs essais cliniques randomisés. Sur le plan curatif, plusieurs options thérapeutiques sont actuellement déployées ou en cours de développement afin de proposer une offre de soins pertinente

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

Abstract 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
