RESUMEN
After failure of first line FOLFOX-bevacizumab for metastatic colorectal cancer (mCRC), adding either bevacizumab or aflibercept to second-line FOLFIRI increases survival compared to FOLFIRI alone. In this French retrospective multicentre cohort, we included patients with a mCRC treated with either FOLFIRI-aflibercept or FOLFIRI-bevacizumab. The primary endpoint was overall survival (OS), and secondary endpoints were progression-free survival (PFS), disease control rate (DCR: CR + PR + SD) and safety. We included 681 patients from 36 centers, 326 and 355 in the aflibercept and bevacizumab groups, respectively. Median age was 64.2 years and 45.2% of patients were men. Most patients had RAS-mutated tumors (80.8%) and synchronous metastases (85.7%). After a median follow up of 31.2 months, median OS was 13.0 months (95% CI: 11.3-14.7) and 10.4 months (95% CI: 8.8-11.4) in the bevacizumab and aflibercept groups, respectively (P < .0001). Median PFS was 6.0 months (95% CI: 5.4-6.5) and 5.1 months (95% CI: 4.3-5.6) (P < .0001). After adjustment on age, PS, PFS of first line, primary tumor resection, metastasis location and RAS/BRAF status, bevacizumab was still associated with better OS (HR: 0.71, 95% CI: 0.59-0.86, P = .0003). FOLFIRI-bevacizumab combination was associated with longer OS and PFS, and a better tolerability, as compared to FOLFIRI-aflibercept after progression on FOLFOX-bevacizumab.

As is the case with most eucaryotic cells, cancer cells are able to secrete extracellular vesicles (EVs) as a communication means towards their environment and surrounding cells. EVs are represented by microvesicles and smaller vesicles called exosomes, which are known for their involvement in cancer aggressiveness. The release of such EVs requires the intervention of trafficking-associated proteins, mostly represented by the RAB-GTPases family. In particular, RAB27A is known for its role in addressing EVs-to-be secreted towards the the plasma membrane. In this study, shRNAs targeting RAB27A were used in colorectal (CRC) and glioblastoma (GB) cell lines in order to alter EVs secretion. To study and monitor EVs secretion in cell lines' supernatants, nanoparticle tracking analysis (NTA) was used through the NanoSight NS300 device. Since it appeared that NanoSight failed to detect the decrease in the EVs secretion, we performed another approach to drop EVs secretion (RAB27A-siRNA, indomethacin, Nexihnib20). Similar results were obtained i.e., no variation in EVs concentration. Conversely, NTA allowed us to monitor EVs up-secretion following rotenone treatment or hypoxia conditions. Therefore, our data seemed to point out the insufficiency of using only this technique for the assessment of EVs secretion decrease.

BACKGROUND: The prognostic value of a low skeletal mass index (SMI) has been investigated in locally advanced oesophageal (LAE) cancer at diagnosis. However, nothing is known about its evolution and clinical impact between initial diagnosis and recurrence. METHODS: A total of 89 patients treated for LAE cancer between January 2009 and December 2019 were included in this study. Computed tomography (CT) scans before treatment and at recurrence were evaluated. SMI and other body composition parameters were analysed by the L3 scan method. RESULTS: Participants were aged 66.0 (36.0-86) years. The incidence of low SMI increased by 12.3% between diagnosis and recurrence (70.7% vs. 83.0%, respectively) over a median follow-up of 16.9 (1.7-101.6) months. Patients with high SMI at diagnosis showed loss of muscle mass (58.0 vs. 55.2 cm2/m2, respectively; Pâ <â 0.001) and decreased body mass index (BMI) (27.9 vs. 26.3 kg/m2, respectively; Pâ =â 0.05), but fat mass was increased (68.9 vs. 72.0 cm2/m2, respectively; Pâ =â 0.01). Patients with low SMI at diagnosis showed no significant changes in body composition parameters and no improvement of SMI, even with nutritional support. Low SMI (hazard ratio [HR]: 1.8; 95% confidence interval [CI]: 1.02-3.16) was an independent predictor (Pâ =â 0.041) of high nutritional risk index (HR: 1.79; 95% CI: 1.03-3.11; Pâ =â 0.039) at diagnosis. CONCLUSIONS: The percentage of patients with a low SMI increased during follow-up. Our data suggest that an assessment of skeletal muscle parameters and nutrition support may be more useful in patients with a high SMI.

INTRODUCTION: The second cycle of medical studies is a key time for developing interpersonal skills and the doctor-patient relationship. High-fidelity simulation is an initial learning option that enables learners to confront situations involving empathy. METHODS: This is a feedback report from May 2023 on the implementation of simulation as a training tool for 2nd cycle medical students in the announcement consultation. The training consists of two parts: theoretical teaching via a digital platform with an assessment of theoretical knowledge and a practical part with a simulation session with an actress playing a standardized patient. The acquisition of skills and the reflexivity of learners are assessed by means of a pre- and post-test. RESULTS: Twenty-nine externs took part in this project. Student satisfaction was 96 %. The feedback was very positive, both in terms of the quality of the sessions and the briefings/debriefings. Almost all the students wanted to repeat the experience. The simulation exercise was beneficial for the students in terms of the development (before vs. after) of their skills (verbal, emotional and relational) (1.05±0.25 vs. 1.22±0.19, P=0.047) and appeared to be relevant to the development of reflexivity (3.29±0.72 vs. 3.48±0.9, P=0.134). CONCLUSION: This first published French study demonstrates the feasibility and value of training in announcing a diagnosis, combining teaching via a digital platform and high-fidelity simulation for second cycle medical students.

Background: In the context of personalized medicine, screening patients to identify targetable molecular alterations is essential for therapeutic decisions such as inclusion in clinical trials, early access to therapies, or compassionate treatment. The objective of this study was to determine the real-world impact of routine incorporation of FoundationOne analysis in cancers with a poor prognosis and limited treatment options, or in those progressing after at least one course of standard therapy. Methods: A FoundationOneCDx panel for solid tumor or liquid biopsy samples was offered to 204 eligible patients. Results: Samples from 150 patients were processed for genomic testing, with a data acquisition success rate of 93%. The analysis identified 2419 gene alterations, with a median of 11 alterations per tumor (range, 0-86). The most common or likely pathogenic variants were on TP53, TERT, PI3KCA, CDKN2A/B, KRAS, CCDN1, FGF19, FGF3, and SMAD4. The median tumor mutation burden was three mutations/Mb (range, 0-117) in 143 patients with available data. Of 150 patients with known or likely pathogenic actionable alterations, 13 (8.6%) received matched targeted therapy. Sixty-nine patients underwent Molecular Tumor Board, which resulted in recommendations in 60 cases. Treatment with genotype-directed therapy had no impact on overall survival (13 months vs. 14 months; p = 0.95; hazard ratio = 1.04 (95% confidence interval, 0.48-2.26)]. Conclusions: This study highlights that an organized center with a Multidisciplinary Molecular Tumor Board and an NGS screening system can obtain satisfactory results comparable with those of large centers for including patients in clinical trials.
RESUMEN
BACKGROUND: The COVID-19 pandemic has changed the organisation of medical care. PATIENTS AND METHODS: This is the first prospective observational study on patient-reported outcomes, quality of life (HRQOL) and satisfaction in patients with cancer with their care management in a day hospital during the period of May-June 2020. The Generalised Anxiety Disorder Screener and 12-Item Short-Form Health Survey were used. RESULTS: The survey was completed by 189 of 267 patients. They were generally aged 61 to 70 years and women and presented with lung, breast, or colorectal cancer. Patients had low anxiety scores (mean: 3.2±4.5), with only 11.1% showing anxiety. Risk factors of anxiety included female gender (p=0.03) and lifestyle (residence, family environment) (p=0.01). The patient's physical health was stable, whereas mental health had deteriorated (p<0.0001). Risk factors of altered HRQOL included age and lifestyle. Patients greatly appreciated all the facilities of the day hospital and its organisation. CONCLUSION: This study shows a preserved HRQOL and low anxiety of patients with cancer during the COVID-19 pandemic.

BACKGROUND/AIM: To investigate the impact of body composition on morbidity and mortality at the initial diagnosis of localised renal cell carcinoma (RCC) in patients with overweight or obesity. PATIENTS AND METHODS: Sarcopenia was defined using sex-specific cut-off points and other body composition parameters by median values with computed tomography imaging. RESULTS: Among the 96 patients, 40 had sarcopenia (43.0%) at diagnosis. Body composition had no effect on morbidity and 5-year disease-free survival contrary to the classic factors (p<0.05). In the subgroup of obese patients, those with sarcopenia had a poor prognosis (p=0.04) but not in the population with overweight (p=0.9). CONCLUSION: Sarcopenia was frequently associated with localised RCC at the initial diagnosis. Body composition did not affect morbidity or outcomes. BMI was involved in morbidity and there was paradoxically longer survival in the obesity group.

Oral therapies have highly modified cancer patient management and changed hospital practises. We introduce a specific Oral Therapy Centre and retrospectively review information prospectively recorded by co-ordination nurses (CNs) (the DICTO programme). We describe the roles played by CNs in the management of oral cancer therapies at Limoges Dupuytren Hospital between May 2015 and June 2018. All cancers, irrespective of stage or whether oral general chemotherapy or targeted therapy was prescribed, are included. We followed up 287 patients of median age 67 years (range 26-89 years). Of these, 76% had metastases and 44% were on first-line therapy. The vast majority (88%) of their first CN contacts occurred just after physician consultation and lasted an average of 60 min. As part of follow-up, the CNs made 2719 calls (average 10 min) to patients to educate them and to verify compliance and drug tolerance. They also received 833 calls from patients (70%) or their relatives or health professionals (30%) seeking advice on management of side effects. In addition to the initial appointments, 1069 non-scheduled follow-up visits were made to assess side effects (49.2%). The CNs devoted 5 h to each patient over 3 months of treatment (i.e. 25 min/day) and, also organised scheduled hospitalisations in the department of oncology for 51% of patients. We show the interest and real-life work in a specific oral therapy centre within oncology department with the role of CNs to facilitate the global health care of the patients.
