Introduction: The Coronavirus (COVID-19) pandemic and its associated health restrictions have harmed the population psychologically. We aimed to compare the post-traumatic stress disorder (PTSD) symptoms and Quality of Life (QoL) in older French patients with cancer to the younger ones., Materials and Methods: This longitudinal multicenter study named COVIPACT began in April 2020 during the first French lockdown and has included 579 outpatients receiving treatment for a solid or hematological malignancy. Data were collected every three months, namely at the first release period (M3), at the second lockdown (M6), at the second release period (M9), and finally at the last curfew period (M12) in France. Standardized validated self-questionnaires were used to assess PTSD symptoms (using the Event Scale-Revised self-questionnaire), insomnia (through the Insomnia Severity Index questionnaire), QoL (using the Functional Assessment of Cancer Therapy - General questionnaire), and cognitive complaints (through the Functional Assessment of Cancer Therapy - Cognition questionnaire). Student (or Wilcoxon) tests and Chi-squared tests were used for continuous or discrete variables, respectively. We conducted linear mixed model to study the change during follow-up., Results: Out of 579 included patients, 157 (27%) were ≥ 70 years old at baseline, of whom 104 participated in the longitudinal study. At baseline, older patients reported fewer PTSD symptoms (17% versus 23%, p = .06), insomnia (17% versus 27%, p = .02), and cognitive complaint (3% versus 16%, p < .01) than younger patients. QoL at baseline was similar between age subgroups. We observed no significant difference in the trajectory of PTSD symptoms, insomnia, or emotional well-being between both groups during the follow-up. Cognitive complaints were lower at baseline in older patients but steadily increased during the follow-up and reached the same level as younger patients at one year., Discussion: One in five older patients reported PTSD symptoms, evolving similarly to younger patients during the first year of the COVID-19 pandemic. While cognitive complaints tend to recover in a bell-shaped curve at one year in younger patients, the trend is increasing in older ones. Screening for PTSD symptoms and late cognitive impairment should be given special attention in older patients., Trial Registration: Clinicaltrials.gov identifier: NCT04366154., Competing Interests: Declaration of Competing Interest Authors declare no conflict of interest with this work., (Copyright © 2023.

Background: Using the large nationwide French, national, multicenter, prospective cancer and toxicities (CANTO) cohort, we assessed cognitive functioning change after cancer treatments in a subgroup of breast cancer (BC) patients., Methods: We included patients with newly diagnosed invasive stage I-III BC enrolled in the CANTO substudy focused on cognitive evaluation and healthy control women matched for age and education. Episodic and working memory, executive functions, processing speed, attention, self-report cognitive difficulties (SRCD), fatigue, anxiety and depression were assessed with neuropsychological tests and self-report questionnaires before treatment (baseline) and approximately 1 (year 1) and 2 years (year 2) after diagnosis. We used linear mixed models to study changes in cognition and tested the effect of adjuvant chemotherapy., Results: We studied 276 localized BC patients (62% chemotherapy) compared with 135 healthy controls (HC). After adjustment, patients had lower baseline working memory, processing speed, and attention scores than HC (P ≤ .001), and the difference remained statistically significant over follow-up for working memory and processing speed. Executive function scores were similar between groups at baseline but decreased at year 1 among patients compared with HC (Pchange = .006). This decrease in chemotherapy patients was statistically significant compared with HC scores (Pchange < .001). After adjustment, SRCD were similar between BC patients and HC at baseline but increased in patients after treatment at year 1 (Pchange = .002)., Conclusions: Cognitive difficulties are an important concern in BC patients, starting at diagnosis. Cancer treatments induce executive function decline and SRCD, which decrease over follow-up., (© The Author(s) 2022. Published by Oxford University Press. All rights reserved.

Objective: Identifying new modifiable prognostic markers is important for ovarian cancer (OC). Low parasympathic activity is associated with inflammation, oxidative stress and sympathetic nervous system activation. Previous studies reported that low vagal nerve activity, measured by low heart rate variability (HRV), may predict poor cancer prognosis. We aimed to examine the prognostic value of HRV in OC., Methods: This bicentric retrospective study included patients diagnosed with serous OC FIGO stage ≥IIB, between January 2015 and August 2019, with electrocardiograms (ECG) available around diagnosis. HRV was measured from ECG using the time domain parameter of standard deviation of all normal-to-normal heartbeat intervals (SDNN). Optimal SDNN cut-off was determined using the Youden index criteria of time-dependent ROC curves. We used multivariate cox proportional hazard models to investigate the association between HRV and overall survival (OS), while adjusting for well-known OC prognostic factors., Results: The 202 patients included were 65.7 years-old on average, 93% had stage FIGO IIIC/IV, 56% had complete surgical resection. Median OS was 38.6 months [95%CI:34.4-47.4]. The median SDNN was 11.1ms, with an optimal cut-off of 10ms to predict OS. OS was shorter for patients with low HRV compared to high HRV (26.4 vs 45.1 months; p<0.001). In multivariate analysis, HRV remained an independent prognostic factor with a two-fold higher risk of death among patients with low SDNN compared to those with high SDNN (HR=2.03, 95%CI=1.35-3.06, p<0.001)., Conclusion: Low HRV, was associated with worse OS in OC patients, supporting previous studies on the prognostic role of HRV in cancer. If replicated in prospective studies, vagal nerve activity may be a new therapeutic target in OC., Competing Interests: FJ reports participating in advisory boards with AstraZeneca, GSK, Clovis, MSD and seagen, reports consulting fees from GSK, and support for attending meetings from GSK, Astrazeneca and MSD.

Objective: 18F-Fluorocholine (18FCH) PET/CT has high sensitivity for parathyroid adenoma detection and can reliably exclude malignancy in thyroid nodules with indeterminate cytology. Data regarding 18FCH uptake in chronic autoimmune thyroiditis (CAT) are scarce. We aimed to assess thyroid 18FCH uptake in CAT with biological and histological correlation., Methods: This is an ancillary study from the Chocolate trial (NCT02784223) that prospectively enrolled 107 patients planned for thyroid surgery. 18FCH PET/CT acquisitions were performed 20 and 60 min after injection. 18FCH uptake in the thyroid gland was assessed by measuring maximum (SUVmax) and mean (SUVmean) standardized uptake values. Thyrotropin, free thyroxine (FT4), thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibodies were collected. The intensity of thyroiditis and the degree of fibrosis were assessed on pathology., Results: CAT was evidenced in 19/107 (18%) patients. Of these, 13 (68%) displayed an increased and diffuse 18FCH thyroid uptake. This uptake pattern was not observed in patients without CAT. SUVmax and SUVmean were higher in patients with CAT than in those without (P < 0.001). At both acquisition times, SUVmax showed a monotonic relationship with the intensity of thyroiditis (Spearman ρ = 0.44 and 0.51, respectively, P < 0.001) and with the degree of fibrosis (Spearman ρ = 0.55 and 0.62, respectively, P < 0.001). SUVmax showed a linear relationship with TPOAb titers at 20 min (Pearson r = 0.54, P < 0.05; Spearman ρ = 0.59, P = 0.03)., Conclusions: More than two-thirds of the patients with CAT present high and diffuse thyroid 18FCH uptake. This uptake pattern is highly specific to CAT and is correlated with pathology and TPOAb titers.

Background: Alleviating suffering and improving quality of life are universally shared goals. In this context, we implemented a pilot study to assess the feasibility and acceptability of a mindfulness intervention in the form of meditation involving together cancer patients, health professionals, and third persons., Methods: Two groups of 15 participants equally composed of patients, health professionals and third persons were constituted. A dedicated programme on mindfulness and compassion was constructed, including 12 weekly sessions of 1.5 h and a half-day retreat. Adherence and satisfaction with the programme were evaluated. All participants completed questionnaires on perceived stress, quality of life, mindfulness, empathy, and self-efficacy. Burnout was assessed in health professionals., Results: Shared meditation was feasible as 70% of participants attended ≥ 80% of the 13 meditation sessions. Satisfaction with the programme was high (median satisfaction score: 9.1 out of 10) and all participants expressed positive attitudes towards shared meditation and a benefit on their global quality of life. Participants reported significant improvement in stress (p < 0.001), global quality of life (p = 0.004), self-efficacy (p < 0.001), and mindfulness skills (p < 0.001) from baseline to post-programme., Conclusions: This study demonstrated the feasibility of a shared dedicated meditation programme in terms of participation and acceptability of participants. The measured benefits observed among participants furthermore justify the interest of a subsequent randomized study aiming to demonstrate the potential added value of shared meditation by promoting bridge-building between cancer patients, health professionals and others., Trial Registration: ClinicalTrials.gov.

Cancer-related cognitive impairment (CRCI) occurs frequently in patients living with cancer, with consequences on quality of life. Recently, research on the management of these difficulties has focused on computerized cognitive stimulation and computerized physical activity programs. This systematic review presents the state of knowledge about interventions based on computerized-cognitive stimulation and/or physical activity to reduce CRCI. The review followed the PRISMA guidelines. A search was conducted in PUBMED and Web of Science databases. Risk of bias analysis was conducted using the Rob2 tool and the quality of evidence was conducted following the GRADE approach. A total of 3776 articles were initially identified and 20 of them met the inclusion criteria. Among them, sixteen investigated computerized-cognitive stimulation and four computerized-physical activity. Most of the studies were randomized controlled trials and assessed the efficacy of a home-based intervention on objective cognition in adults with cancer. Overall, cognitive improvement was found in 11/16 computerized-cognitive stimulation studies and 2/4 computerized-physical activity studies. Cognitive stimulation or physical activity improved especially cognitive complaints, memory, and attention. These results suggest the efficacy of both computerized-cognitive stimulation and physical activity. However, we report a high risk of bias for the majority of studies and a low level of quality of evidence. Therefore, further investigations are needed to confirm the efficacy of these interventions and to investigate the possible added benefit on cognition of a combined computerized-cognitive/physical intervention.

Cancer-related cognitive impairment (CRCI) is a frequent side-effect of cancer treatment, with important consequences on patients' quality of life. Cognitive stimulation and physical activity are the most efficient in improving cognitive impairment, but they are challenging to generalize in hospitals' routine and to patients' needs and schedules. Moreover, the added value of a combination of these interventions needs to be more investigated. The Cog-Stim study is an interventional study investigating the feasibility of a web-based multimodal intervention (combining cognitive stimulation and physical activity for the improvement of cognitive complaints among breast-cancer patients currently treated with radiotherapy ( n = 20). Patients will take part in a 12-week program, proposing two sessions per week of web-based cognitive stimulation (20 min/session with HappyNeuron ® ) and two sessions per week of web-based physical activity (30 min/session with Mooven ® platform). Cognitive complaints (FACT-Cog) and objective cognitive functioning (CNS Vital Signs ® ), anxiety, depression (HADS), sleep disorders (ISI) and fatigue (FACIT-Fatigue) will be assessed before and after the intervention. The primary endpoint is the adherence rate to the intervention program. Patients' satisfaction, reasons for non-attrition and non-adherence to the program will also be assessed. The overall goal of this study is to collect information to develop web-based interventions for cognitive difficulties in supportive care units.

Background: Diet has been recognized as a modifiable risk factor for breast cancer. Highlighting predictive diet-related biomarkers would be of great public health relevance to identify at-risk subjects. The aim of this exploratory study was to select diet-related metabolites discriminating women at higher risk of breast cancer using untargeted metabolomics., Methods: Baseline plasma samples of 200 incident breast cancer cases and matched controls, from a nested case-control study within the Supplémentation en Vitamines et Minéraux Antioxydants (SU.VI.MAX) cohort, were analyzed by untargeted LC-MS. Diet-related metabolites were identified by partial correlation with dietary exposures, and best predictors of breast cancer risk were then selected by Elastic Net penalized regression. The selection stability was assessed using bootstrap resampling., Results: 595 ions were selected as candidate diet-related metabolites. Fourteen of them were selected by Elastic Net regression as breast cancer risk discriminant ions. A lower level of piperine (a compound from pepper) and higher levels of acetyltributylcitrate (an alternative plasticizer to phthalates), pregnene-triol sulfate (a steroid sulfate), and 2-amino-4-cyano butanoic acid (a metabolite linked to microbiota metabolism) were observed in plasma from women who subsequently developed breast cancer. This metabolomic signature was related to several dietary exposures such as a "Western" dietary pattern and higher alcohol and coffee intakes., Conclusions: Our study suggested a diet-related plasma metabolic signature involving exogenous, steroid metabolites, and microbiota-related compounds associated with long-term breast cancer risk that should be confirmed in large-scale independent studies., Impact: These results could help to identify healthy women at higher risk of breast cancer and improve the understanding of nutrition and health relationship., (©2019 American Association for Cancer Research.)
