Genomic signature to guide adjuvant chemotherapy treatment decisions for early breast cancer patients in France: a cost-effectiveness analysis.

Introduction: Chemotherapy (CT) is commonly used as an adjuvant treatment for women with early breast cancer (BC). However, not all patients benefit from CT, while all are exposed to its short- and long-term toxicity. The Oncotype DX® test assesses cancer-related gene expression to estimate the risk of BC recurrence and predict the benefit of chemotherapy. The aim of this study was to estimate, from the French National Health Insurance (NHI) perspective, the cost-effectiveness of the Oncotype DX® test compared to standard of care (SoC; involving clinicopathological risk assessment only) among women with early, hormone receptor-positive, human epidermal growth factor receptor 2-negative BC considered at high clinicopathological risk of recurrence. Methods: Clinical outcomes and costs were estimated over a lifetime horizon based on a two-component model that comprised a short-term decision tree representing the adjuvant treatment choice guided by the therapeutic decision support strategy (Oncotype DX® test or SoC) and a Markov model to capture long-term outcomes. Results: In the base case, the Oncotype DX® test reduced CT use by 55.2% and resulted in 0.337 incremental quality-adjusted life-years gained and cost savings of €3,412 per patient, compared with SoC. Being more effective and less costly than SoC, Oncotype DX® testing was the dominant strategy. Discussion: Widespread implementation of Oncotype DX® testing would improve patient care, provide equitable access to more personalized medicine, and bring cost savings to the health system.

Feasibility of health-related quality of life (HRQoL) assessment for cancer patients using electronic patient-reported outcome (ePRO) in daily clinical practice.

INTRODUCTION: Routine Electronic Monitoring of Health-Related Quality of Life (HRQoL) (REMOQOL) in clinical care with real-time feedback to physicians could help to enhance patient-centered care. We evaluated the feasibility of REMOQOL in the French context in the QOLIBRY study. The primary objective was to assess the patients' compliance with REMOQOL. METHODS: The QOLIBRY study was a single-center, prospective study conducted in the University Hospital of Besançon (France). Eligible patients were those treated with systemic therapies for breast, lung or colorectal cancer at any stage. Patients were invited to complete the EORTC QLQ-C30 questionnaire and cancer-site-specific modules before each visit on tablets and/or computers in the hospital or at home. During the consultation, physicians had real-time access to visual summaries of HRQoL scores. Compliance was assessed as adequate if at least 66% of HRQoL assessments were completed during the 4 months of follow-up. RESULTS: Between March 2016 and October 2018, 177 patients were included in the QOLIBRY study. Median age was 64 years (IQR 54-71). The proportion of patients with an adequate compliance rate was 95.5% (n = 63) in the breast cancer cohort, 98.2% (n = 55) in the colorectal cancer cohort, and 90.9% (n = 50) in the lung cancer cohort. The physicians checked the HRQoL results in 73.1% of visits and prescribed supportive care and adapted patient management in 8.3% and 5.2% of visits, respectively. CONCLUSION & PERSPECTIVES: The results of QOLIBRY study suggest that REMOQOL is feasible in the French context. However, information about HRQoL monitoring, training of the physicians in the use of the software, and recommendations for using HRQoL results to guide care are essential and must be improved.

[Adjuvant hormonal therapy for early breast cancer: Assessment of patients' satisfaction]. / Évaluation de la satisfaction de patientes atteintes d'un cancer du sein précoce traitées en adjuvant par hormonothérapie.

INTRODUCTION: Since the cancer plan, evaluation of professional practices is essential to ensure the implementation of high-quality health care. Assess patient satisfaction is one of the pillars of high-quality health care. The main objective of the study was to assess the satisfaction of patients with early breast cancer taking a hormonal therapy, the secondary objective was to identify factors associated with their satisfaction. METHODS: The modified EORTC OUT-PATSAT-35 questionnaire was sent to a sample of patients in Franche-Comté in order to evaluate nine dimensions of satisfaction among which interpersonal skills, provided information, and overall satisfaction. For each dimension, a satisfaction score between 0 (no satisfaction) and 100 (highest satisfaction) was measured. Logistic regression analyses were used to study the factors associated with satisfaction. RESULTS: The mean overall satisfaction score for the 280 patients who answered was 73 [0-100]. Practicing an extra-professional activity was associated with higher satisfaction for several dimensions (odds ratio between 2.80 and 4.12, P<0.05) whereas it was decreased in the case of a modified appetite (odds ratio between 0.27 and 0.52, P<0.05). No link has been shown between satisfaction and adherence. DISCUSSION: The patients were satisfied and several factors impacting their satisfaction were identified, based on a questionnaire that must evolve to take into account the ambulatory aspect of their care. During the consultations, particular attention will be paid to these factors.

Complementary and alternative medicine use in glioma patients in France.

PURPOSE: Complementary and alternative medicine (CAM) use increases in cancer patients, including adult patients with diffuse gliomas. METHODS: Questionnaires addressing CAM use were distributed to adult patients with gliomas of WHO grades II-IV and ECOG performance score of 0-2 during hospital visits and filled in anonymously. The study was conducted in nine centers in France from May 2017 to May 2018. Descriptive cohort analyses and comparative analyses according to gender, age, WHO grade, and recurrent versus newly diagnosed disease were conducted. RESULTS: Two hundred twenty-seven questionnaires were collected; 135 patients (59%) were male. Median age was 48 years, 105 patients (46%) declared having glioblastoma, 99 patients (43%) declared having recurrent disease. Hundred-three patients (45%) had modified their alimentary habits after the glioma diagnosis. At the time of the questionnaire, 100 patients (44%) were on complementary treatment, mainly vitamins and food supplements, and 73 patients (32%) used alternative medicine approaches, mainly magnetism and acupuncture. In total, 154 patients (68%) declared using at least one of these approaches. Expenditures exceeding 100 € per month were reported by users in 14% for modification of alimentary habits, in 25% for complementary treatment, and in 18% for alternative medicines. All approaches were commonly considered as improving quality of life and experienced as efficient, notably those associated with more expenditures. CONCLUSIONS: CAM are frequently used by glioma patients in France. Underlying needs and expectations, as well as potential interactions with tumor-specific treatments, and financial and quality of life burden, should be discussed with patients and caregivers.

Milestones over the development of SB3, a trastuzumab biosimilar.

The development of a biosimilar requires large extensive preclinical and clinical comparability exercises to demonstrate equivalence to the reference medical product. The holistic results from this large assessment should be taken into account to appreciate the validity of the development and the interpretations. SB3 is the first trastuzumab biosimilar approved for routine use in Europe. The present manuscript reviews the development and the results of SB3, including clinical assessment and the clinical Phase I, as well as the large randomized Phase III comparing efficacy between SB3 versus Herceptin® containing regimen in neoadjuvant setting. Key points of the design and interpretations of the findings are extensively discussed in this review of SB3 development.

Assessment of the prognostic role of a 94-single nucleotide polymorphisms risk score in early breast cancer in the SIGNAL/PHARE prospective cohort: no correlation with clinico-pathological characteristics and outcomes.

BACKGROUND: Genome-wide association studies (GWAS) have to date identified 94 genetic variants (single nucleotide polymorphisms (SNPs)) associated with risk of developing breast cancer. A score based on the combined effect of the 94 risk alleles can be calculated to measure the global risk of breast cancer. We aimed to test the hypothesis that the 94-SNP-based risk score is associated with clinico-pathological characteristics, breast cancer subtypes and outcomes in early breast cancer. METHODS: A 94-SNP risk score was calculated in 8703 patients in the PHARE and SIGNAL prospective case cohorts. This score is the total number of inherited risk alleles based on 94 selected SNPs. Clinical data and outcomes were prospectively registered. Genotyping was obtained from a GWAS. RESULTS: The median 94-SNP risk score in 8703 patients with early breast cancer was 77.5 (range: 58.1-97.6). The risk score was not associated with usual prognostic and predictive factors (age; tumor, node, metastasis (TNM) status; Scarff-Bloom-Richardson grade; inflammatory features; estrogen receptor status; progesterone receptor status; human epidermal growth factor receptor 2 (HER2) status) and did not correlate with breast cancer subtypes. The 94-SNP risk score did not predict outcomes represented by overall survival or disease-free survival. CONCLUSIONS: In a prospective case cohort of 8703 patients, a risk score based on 94 SNPs was not associated with breast cancer characteristics, cancer subtypes, or patients' outcomes. If we hypothesize that prognosis and subtypes of breast cancer are determined by constitutional genetic factors, our results suggest that a score based on breast cancer risk-associated SNPs is not associated with prognosis.

[Prevalence and management of pain in patients with metastatic cancer in Franche-Comté]. / Prévalence et prise en charge de la douleur chez les patients présentant un cancer métastatique en Franche-Comté.

INTRODUCTION: Pain management is a major public health problem, especially in oncology. In order to assess professional practice, the IRFC-FC conducted a survey amongst patients with metastatic osteophilic solid tumor in Franche-Comté. The aims were to assess the pain prevalence, and its characteristics, its management and its impact on patients' quality of life in patients in pain. METHODS: An observational, prospective and multicenter survey was conducted using a self-report questionnaire. Patients with metastatic breast or prostate cancer managed in 5 day-hospitals of the IRFC-FC over a period of three months were included. RESULTS: Two hundred thirty-three questionnaires were analyzed. Pain prevalence rate was 48.5%. Three quarters of patients in pain had chronic background pain, moderate to severe, with or without breakthrough pain. Considering their pain intensity and their analgesic therapy, 42.0% of patients seem to have an inadequate treatment. Eighty-five percent of treated patients reported to be compliant and felt that their pain was well managed despite a strong impact on their quality of life. CONCLUSION: The setting of a specific clinical pathway is essential to secure the standardized, optimal and efficient management of patients in pain. The assessment of patient satisfaction and quality of life must be integrated in clinical practice to identify patients in pain for which the treatment is inappropriate.

[Efficacy, safety and cost of eribulin in patients with metastatic breast cancer]. / Efficacité, tolérance et coût de l'éribuline chez des patientes présentant un cancer du sein métastatique.

Eribulin gained its approval in March 2011 for the treatment of patients with locally advanced or metastatic breast cancer (MBC) whose disease has progressed despite anthracycline and taxane-containing regimens. This study retrospectively assessed the efficacy, safety and cost of this treatment for all patients with MBC treated by eribulin in Franche-Comté. Ninety-four patients received eribulin between July 2006 and October 2013. The median age was 62 years (35-83). Median overall survival was 10.3 months [95% CI: 7.6 to 17.9]. Median progression-free-survival was 3.8 months [95% CI: 2.9 to 5.0]. Clinical benefit was obtained in 55% evaluable patients [95% CI: 43.1 to 66.9] by RECIST criteria. Most common grade 3-4 adverse events (AEs) were neutropenia (38%), asthenia (10%) and peripheral neuropathy (7%). Median cost of the treatment was 9767 € per patient (6344-17,517). This analysis found similar results to the EMBRACE study despite less selected population. A medico-economic evaluation cost-utility type would assess the effectiveness of this strategy compared to standard treatments.

[Economic assessment of the routine use of Oncotype DX® assay for early breast cancer in Franche-Comte region]. / Évaluation économique de l'utilisation en routine du test Oncotype DX® dans la prise en charge des cancers du sein en Franche-Comté.

Oncotype DX® has been validated as quantifying the likelihood of distant recurrence at 10 years and overall chemotherapy benefit in patients with estrogen-receptor-positive and HER-2-negative early breast cancer. In 2012, this genomic signature was routinely available for patients in Franche-Comté, France. Patients eligible for Oncotype DX(®) testing had a ER-positive, HER-2-négative early breast cancer with a nodal involvement limited to 0 or 1 positive-node without extracapsular spread; an adjuvant chemotherapy was indicated based on usual prognostic factors. The aim was to assess the economic impact of Oncotype DX(®) testing in a French region. A cost-minimisation analysis from the French Public Healthcare System perspective was performed. The availability of Oncotype DX(®) in Franche-Comté, France, and its use in clinical routine allowed a decrease of 73 % of adjuvant chemotherapy without increase of the cost of the patients' management and with a potential reduction of the cost for the French Public Healthcare System. This strategy was successful and may allow the reimbursement of this test in France for patients with early breast cancer.
