Patient navigation for colorectal cancer screening in deprived areas: the COLONAV cluster randomized controlled trial.

BACKGROUND: The objective of this study was to assess the effectiveness of a Patient Navigation Intervention targeting deprived patients for Colo-Rectal Cancer (CRC) screening participation. METHODS: A cluster randomized controlled trial was conducted in 5 districts. Peer Lay Patient Navigators were recruited to operate in deprived areas. Eligible participants had to be between 50 and 74 years old, live in these deprived areas and receive an invitation to the nationally organized Colo-Rectal Cancer (CRC) screening during the study period. The theory-driven navigation intervention was deployed for 18 months. A population Health Intervention Research assessment method was used to assess effectiveness and context interaction. The primary criterion was screening participation at 12 months. RESULTS: Twenty-four thousand two hundred eighty-one individuals were included inside 40 clusters. The increase in participation in the intervention group was estimated at 23%, (ORa = 1.23, CI95% [1.07-1.41], p = 0.003). For the subgroup of individuals who participated, the time delay to participating was reduced by 26% (ORa = 0.74, CI95% [0.57-0.96], p = 0.021). Main factors modulating the effect of the intervention were: closeness of navigator profiles to the targeted population, navigators' abilities to adapt their modus operandi, and facilitating attachment structure. CONCLUSION: The ColoNav Intervention succeeded in demonstrating its effectiveness, for CRC screening. Patient Navigation should be disseminate with broader health promotion goals in order to achieve equity in health care. TRIAL REGISTRATION: clinicaltrials.gov NCT02369757 24/02/2015.

Suggestibility, Facebook use and relationship with substance addictive behaviors.

OBJECTIVE: Several health issues related to the us of social networking sites (SNS) are documented. One concept that is not clearly studied is suggestibility as the tendency of a person to accept and internalize communication. The aim of the study is to test a model in which suggestibility of people can predict SNS use, which in turn can predict substance use. METHODS: Participants answered a questionnaire measuring suggestibility, alcohol consumption, dependence to nicotine and Facebook use. Linear regression and a structural equation model (SEM) were carried out to assess which utilization of Facebook variables explained best the level of alcohol consumption or nicotine dependence and to assess how suggestibility predicted Facebook use. RESULTS: Linear regression analyses indicate that only the number of friends on Facebook is a predictor of the level of alcohol consumption (P<0.001). Suggestibility predict the frequency of Facebook use (P<0.001) and of the number of friends on Facebook (P=0.022). The SEM demonstrates that participants with a higher level of suggestibility have more friends on the SNS, which can influence substance consumption. CONCLUSION: Individuals' level of suggestibility affects Facebook use. People with a higher level of suggestibility are more likely to have many friends on the SNS resulting in a possible environmental influence on substance use.

Cancer-related fatigue management: evaluation of a patient education program with a large-scale randomised controlled trial, the PEPs fatigue study.

BACKGROUND: To assess the efficacy of a patient educational program built according to guidelines that aims at reducing cancer-related fatigue (CRF). METHODS: Randomised controlled trial, multicentre, comparing a patient education program, vs the standard of care. Patients were adult cancer outpatients with any tumour site. The primary outcome was fatigue severity assessed with a visual analogical scale (VAS), between the day of randomisation and week 7. Secondary outcomes were fatigue assessed with other scales, health-related quality of life, anxiety and depression. The time to fatigue severity deterioration was assessed. Analyses were performed in a modified intent-to-treat way, that is, including all patients with at least one baseline and 1 week 7 score. RESULTS: A total of 212 patients were included. Fatigue severity assessment was made on 79 patients in the experimental group and 65 in the control group. Between randomisation and week 7, the fatigue (VAS) improved by 0.96 (2.85) points in the experimental group vs 1.63 (2.63) points in the control group (P=0.15). No differences with the secondary outcomes were highlighted between two groups. No other factors were found to be associated with fatigue severity deterioration. CONCLUSIONS: Despite rigorous methodology, this study failed to highlight the program efficacy in fatigue reduction for cancer patients. Other assessment tools should be developed to measure the effect of the program on CRF and behaviour. The implementation of the program should also be explored in order to identify its mechanisms and longer-term impact.

Genomic alterations and radioresistance in breast cancer: an analysis of the ProfiLER protocol.

BACKGROUND: Breast cancer (BC) patients with comparable prognostic features have heterogeneous outcomes, party related to a possible radiotherapy resistance leading to local-regional recurrences (LRR). The objective of the present study was to identify predictive molecular biomarkers of LRR of BC. PATIENTS AND METHODS: Genetic profile of 146 BC patients' tumours included in the ProfiLER clinical trial (NC01774409) between 2013 and 2016 were analysed using next-generation-sequencing and comparative-genomic-hybridization tests. Patients and tumour characteristics were retrospectively collected and analysed for association with genomic rearrangements (mutations, amplification, deletions). Only gene alterations observed in >3% of the tumours were selected. RESULTS: A total of 193 genomic rearrangements were identified, and 16 were observed in >3% of tumours. One was statistically correlated to the risk of local relapse. A median loco-regional progression-free survival (LRPFS) of 23.6 years was reported for PIK3CA mutation carriers (n = 31, 21.2%) versus 9.9 years for PIK3CA wild-type patients (HR 0.27, 95% CI 0.12-0.65, P = 0.002 in univariate analysis). PIK3CA mutation was identified as an independent protective factor on LRR using multivariate analysis (HR 0.29, 95% CI 0.09-0.99, P = 0.047). All other mutations, amplifications or deletions were not found associated with LRPFS. CONCLUSION: PIK3CA mutation was associated with a lower risk of local relapse in this population of BCs. This is consistent with recent studies suggesting PIK3CA to be part of biological pathways impacting the radiosensitivity.

Design and validation of a self-administered questionnaire as an aid to detection of occupational exposure to lung carcinogens.

OBJECTIVE: Ten to thirty percent of lung cancer is thought to be of occupational origin. Lung cancer is under-declared as an occupational disease in Europe, and most declarations of occupational disease concern asbestos. The purpose of this study was to design and validate a short, sensitive self-administered questionnaire, as an aid for physicians in detecting occupational exposure to asbestos and other lung carcinogens in order to remedy occupational lung cancer under-declaration. STUDY DESIGN: Cross-sectional study. METHODS: A short (30-question) self-administered questionnaire was drawn up by oncologist-pneumologists and occupational physicians, covering situations of exposure to proven and probable lung carcinogens. Understanding and acceptability were assessed on 15 lung cancer patients. Validity and reliability were assessed on 70 lung cancer patients by comparison against a semi-directive questionnaire considered as gold standard. Sensitivity and specificity were assessed by comparing responses to items on the two questionnaires. Reliability was assessed by analysing the kappa concordance coefficient for items on the two questionnaires. RESULTS: Sensitivity was 0.85 and specificity 0.875. Concordance between responses on the two questionnaires was 85.7%, with a kappa coefficient of 0.695 [0.52-0.87]. Mean self-administration time was 3.1 min (versus 8.12 min to administer the gold-standard questionnaire). In 16 patients, the self-administered questionnaire detected lung carcinogen exposure meeting the criteria for occupational disease. CONCLUSION: The present short, easy-to-use self-administered questionnaire should facilitate detection of occupational exposure to lung carcinogens. It could be used in occupational lung cancer screening and increase the presently low rate of application for recognition of lung cancer as an occupational disease.

ColoNav: patient navigation for colorectal cancer screening in deprived areas - Study protocol.

BACKGROUND: The mass colorectal cancer screening program was implemented in 2008 in France, targeting 16 million French people aged between 50 and 74. The current adhesion is insufficient and the participation rate is even lower among the underserved population, increasing health inequalities within our health care system. Patient Navigation programs have proved their efficiency to promote the access to cancer screening and diagnosis. METHODS/DESIGN: The purpose of the study is to assess the implementation of a patient navigation intervention that has been described in another cultural environment and another health care system. The main objective of the program is to increase the colorectal cancer screening participation rate among the deprived population through the intervention of a navigator to promote the Fecal Occult Blood Test (FOBT) and complementary exams. We performed a multisite cluster randomized controlled trial, with three groups (one experimental group and two control groups) for 18 months. DISCUSSION: The study attempts to give a better understanding of the adhesion barriers to colorectal cancer screening among underserved populations. If this project is cost-effective, it could create a dynamic based on peer approaches that could be developed for other cancer screening programs and other chronic diseases. TRIAL REGISTRATION: NCT02369757.

Is oral chemotherapy prescription safe for patients? A cross-sectional survey.

BACKGROUND: Oral chemotherapies are increasingly prescribed. Yet wide variations in prescription practices and in monitoring of toxicity have been underlined despite existing guidelines. There is little recent information available as regard to these practices. We aimed to obtain exhaustive information on oral chemotherapy prescription practices and safety monitoring in French hospitals. METHODS: A cross-sectional multicentre survey was carried out to collect information on drug prescription, administration and surveillance: prescribing practices, coordination and monitoring of adherence, safety monitoring and side-effects occurrence prevention. Participants were a large sample of the French oncologists prescribing oral chemotherapy (20%). RESULTS: One hundred and fifty-seven oncologists from 112 hospitals (public, comprehensive cancer centres and private) replied (23.7% of cancer hospitals). The majority (56.1%) of the prescriptions were hand-written on a blank sheet. Eighty-four physicians (53.5%) included dose information and 36 (23%) declared having no monitoring procedures for adherence. Only 84 responders (54%) provided education material at first prescription of oral chemotherapy in way to limit avoidable side-effects. Sixty-one (39%) responders stated that they recalled at least one serious adverse event in the previous year declared in their centre. CONCLUSIONS: In this 2012 study, the majority of prescribers followed no standards in prescription writing, safety monitoring and toxicity prevention. The implementation of the international recommendations for oral chemotherapy administration should be considered as a top priority-for both prescribers and health authorities-as regards to the dynamic of development of these molecules and their potential side-effects.

Development of a geriatric vulnerability score in elderly patients with advanced ovarian cancer treated with first-line carboplatin: a GINECO prospective trial.

BACKGROUND: Two previous GINECO elderly specific studies in advanced ovarian cancer (AOC) patients highlighted the prognostic value of geriatric covariates for overall survival (OS). PATIENTS AND METHODS: This open-label prospective trial was designed to identify the impact of geriatric covariates on OS in AOC patients ≥70 years treated with first-line carboplatin. RESULTS: Geriatric covariates of the 111 patients included median age 79 years (≥80 years: 41%); performance status (PS) ≥2: 47%; ≥3 major comorbidities: 24%; ≥4 comedications: 68%; activities of daily living (ADL) score <6: 55%; instrumental activities of daily living (IADL) score <25: 69%; Hospital Anxiety and Depression Scale (HADS) >14: 37%. The median OS was 17.4 months. Overall, 74% of patients completed the six planned chemotherapy cycles. Grade 3-4 haematological toxic effects were frequent (50%) but manageable. Grade 3-4 non-haematological toxicities included fatigue (15%), anorexia (12%), infections (9%) and thrombosis (2%). A survival score = exp(0.327*GVS) was developed, where the geriatric vulnerability score (GVS) is the sum of the following (each assigned a value of one): albuminaemia <35 g/l; ADL score <6; IADL score <25; lymphopaenia <1 G/l; and HADS >14. With a cut-off ≥3, GVS discriminated two groups with significantly different OS, treatment completion, severe adverse events and unplanned hospital admissions rates. CONCLUSIONS: The GVS is a valuable tool for identifying vulnerable patients when treating an elderly AOC population.

[Predictors of asthenia in breast and prostate cancer patients undergoing curative radiotherapy]. / Facteurs de risque d'asthénie en cours de la radiothérapie des cancers du sein et de la prostate.

PURPOSE: Patients frequently report asthenia during radiation. The present study aimed at identifying the correlation between numerous clinical and tumoral factors and asthenia in breast and prostate cancer patients treated by curative radiotherapy. MATERIALS AND METHODS: A retrospective study was conducted at the Lucien Neuwirth Cancer Institute (France). All breast and prostate cancer patients undergoing curative radiotherapy during 2015 were screened (n=806). Patient's self-evaluation of asthenia and radiotherapy tolerance was assessed through verbal analogic scale (0/10 to 10/10). Data about toxicities, travel distance and travel time, tumor's characteristics, radiotherapy treatment planning, previous cancer therapies, were collected from medical records. RESULTS: 500 patients were included (350 in the breast cancer group and 150 in the prostate cancer group). In all, 86% of patients in the breast cancer group reported asthenia, with a 5/10 median score. In all, 54% of patients in the prostate cancer group reported asthenia, with a 2/10 median score. Univariate analysis showed correlation between asthenia and radiotherapy tolerance as well as tumor staging, in the prostate cancer group. No other correlation was evidenced. CONCLUSION: Radiotherapy-related fatigue is a common side effect. This study showed that most of the factors related to patients or disease that are commonly used to explain fatigue during curative treatments, seem finally to be not correlated with asthenia.

A phase 1/2 trial of lenalidomide and dexamethasone in adult patients with refractory/relapsed acute lymphoblastic leukemia.

OBJECTIVES: Adult patients with refractory/relapsed ALL have poor survival outcomes with current chemotherapies. We aimed to determine safety and efficacy of lenalidomide, an oral immunomodulator, in these patients. METHODS: This phase 1/2 trial (EUDRACT # 2009-009372-13) included 10 patients who received 28-day cycles of oral lenalidomide 25 mg/day, days 1 through 21, in combination with oral dexamethasone 40 mg/day on days 1, 8, 15, 22. Primary endpoints were tolerance and the overall response rate (ORR). Secondary endpoints included overall survival (OS) and quality of life. RESULTS: The most common grade 3 or 4 adverse events were myelosuppression. The ORR among the participants who could be evaluated was 28.6% (95% confidence interval [CI], 0-62.2%). The median OS was 92 days (range, 43-133 days). All patients have died because of progressive disease. Quality of life remains stable during treatment cycles. DISCUSSION AND CONCLUSION: The safety of combination therapy consisting of lenalidomide plus dexamethasone is consistent with ambulatory administration. Efficacy should be reevaluated in a larger series including patients less intensively previously treated.
