RESUMEN
BACKGROUND: Currently available predictive models for chemotherapy-related toxicity are not sufficiently discriminative in older patients with cancer and do not consider moderate toxicities. The purpose of this study was to identify factors associated with moderate and severe chemotherapy toxicities in older patients with cancer. MATERIALS AND METHODS: Patients aged 70+ recruited in the prospective ELCAPA cohort were analyzed. A total of 837 patients with data on toxicities had received chemotherapy without other systemic treatment and were included between 2015 and 2022. To adjust for any imbalances in the distribution of covariates between patients receiving single-agent chemotherapy vs combination chemotherapy, we applied overlap weighting (a propensity-score-based technique). We used multinomial logistic regression. RESULTS: Median (interquartile range) age was 81 (77-84). Forty-one percent experienced moderate toxicity, and 33% experienced severe toxicity. Hematologic toxicities accounted for 53% of severe toxicities and 66% of moderate toxicities. Age <80 years, cancer type, metastatic status, Eastern Cooperative Oncology Group performance status (ECOG-PS) >1, no cognitive impairment were associated with combination chemotherapy decision. In a univariate analysis with overlap weighting, no factors were associated with moderate toxicity. Hemoglobin <â 0 g/dL and a CIRS-G score >12 were associated with severe toxicity. In a multivariate analysis, only hemoglobinâ <â 10 g/dL was independently associated with severe toxicity, adjusted OR 2.96 (95% CI, 1.20-7.29). CONCLUSION: By addressing indication bias for combination chemotherapy decision, only anemia and not cancer type, combination chemotherapy was predicting for severe chemotherapy-related toxicity in older patients with cancer. We did not find any predictors of moderate chemotherapy-related toxicity.
RESUMEN
BACKGROUND: The endocannabinoid (eCB) system and the serotonin (5-HT) are both implicated in the severity of the depression. 5-HT is synthesized from the amino acid tryptophan (Trp), which is also a precursor for kynurenine (Kyn) whose production is increased at the expense of 5-HT in depressed patients. No clinical studies have investigated the crosstalk between the eCB system and the Trp/5-HT/Kyn pathways. Here, we hypothesized that the eCB system is associated with an enhanced Kyn production in relation to the severity of depressive symptoms. METHODS: Eighty-two subjects (51 patients with a diagnosis of depressive disorder (DSM-5) and 31 healthy volunteers), were assessed with the Montgomery-Åsberg Depression Rating Scale (MADRS), Beck Depression Scale, and Global Clinical Impression. Serum concentrations of eCBs (N-arachidonoylethanolamine (AEA) and 2-arachidonoylglycerol (2-AG)); structurally related fatty acyl compounds 2-oleoylglycerol (2-OG), oleoylethanolamide (OEA), and palmitoylethanolamide (PEA); Trp, Kyn, Kyn/Trp ratio (an index of Trp degradation into Kyn) and 5-HT were also determined. RESULTS: Following a principal component analysis including the severity of depression, Kyn and the Kyn/Trp ratio appear to be directly associated with 2-AG, AEA, and PEA. Interestingly, these biomarkers also permitted to distinguish the population into two main clusters: one of individuals having mild/severe depressive symptoms and the other with an absence of depressive symptoms. Using parametric analysis, higher serum levels of 2-AG, Kyn, and the ratio Kyn/Trp and lower levels of Trp and 5-HT were found in individuals with mild/severe depressive symptoms than in those without depressive symptoms. While in asymptomatic people, PEA was directly associated to Trp, and OEA indirectly linked to 5-HT, in individuals with depressive symptoms, these correlations were lost, and instead, positive correlations between AEA and 2-AG, PEA and AEA, and PEA vs 2-AG and OEA concentrations were found. CONCLUSIONS: Parametric and non-parametric analyses suggest a possible association between eCBs, tryptophan/kynurenine biomarkers, and severity of depression, confirming a likely interplay among inflammation, stress, and depression. The enhanced relationships among the biomarkers of the 2-AG and AEA pathways and related lipids seen in individuals with depressive symptoms, but not in asymptomatics, suggest an altered metabolism of the eCB system in depression.

PURPOSE: Second malignancy is a rare but potentially lethal event after prostate brachytherapy, but data remain scarce on its long-term risk. The objective of this study is to estimate the number of pelvic second malignancies following brachytherapy compared to radical prostatectomy (RP). MATERIALS AND METHODS: We retrospectively reviewed patients treated with low-dose 125I brachytherapy and RP in British Columbia from 1999 to 2010. Kaplan-Meier estimates for pelvic (bladder and rectum), invasive pelvic, any second malignancy, and death from any second malignancy were assessed. Cox multivariable analyses were performed adjusting for initial treatment type, age, post-RP adjuvant/salvage external beam radiation therapy status, and smoking history. RESULTS: Two thousand three hundred seventy-eight brachytherapy and 9089 RP patients were included. Median age was 66 years (interquartile range [IQR] 61-71) and 63 years (IQR 58-67), respectively. Median follow-up time to event or censured was 14 years (IQR 11.5-17.3). The Kaplan-Meier estimates for pelvic second malignancy at 15 and 20 years were 6.4% and 9.8%, respectively, after brachytherapy, and 3.2% and 4.2% after RP. Time to any second malignancy and time to death from any second malignancy were not significantly different (P > .05). On Cox multivariable analysis, brachytherapy, compared to surgery, was an independent factor for pelvic (hazard ratio [HR] 1.81 [95% CI 1.45-2.26], P < .001) and invasive pelvic second malignancy (HR 2.13 [95% CI 1.61-2.83], P < .001). Increased age and smoking were also associated with higher estimates of events (P < .001). CONCLUSIONS: After adjustment for age, post-RP adjuvant/salvage external beam radiation therapy status, and smoking status, numerically higher long-term HRs of pelvic and invasive pelvic second malignancy in patients treated with brachytherapy compared to RP were noted.

BACKGROUND: The identification of factors involved in the conversion across the different Alzheimer's disease (AD) stages is crucial to prevent or slow the disease progression. We aimed to assess the factors and their combination associated with the conversion across the AD stages, from mild cognitive impairment to dementia, at a mild, moderate or severe stage and to identify profiles associated with earliest/latest conversion across the AD stages. METHODS: In this study conducted on the real-life MEMORA cohort data collected from January 1, 2013, and December 31, 2019, three cohorts were selected depending on the baseline neurocognitive stage from a consecutive sample of patients attending a memory center, aged between 50 and 90 years old, with a diagnosis of AD during the follow-up, and with at least 2 visits at 6 months to 1 year of interval. A machine learning approach was used to assess the relationship between factors including socio-demographic characteristics, comorbidities and history of diseases, prescription of drugs, and geriatric hospitalizations, and the censored time to conversion from mild cognitive impairment to AD dementia, from the mild stage of dementia to the moderate or severe stages of AD dementia, and from the moderate stage of AD dementia to the severe stage. Profiles of earliest/latest conversion compared to median time to conversion across stages were identified. The median time to conversion was estimated with a Kaplan-Meier estimator. RESULTS: Overall, 2891 patients were included (mean age 77±9 years old, 65% women). The median time of follow-up was 28 months for mild cognitive impairment (MCI) patients, 33 months for mild AD dementia and 30 months for moderate AD dementia. Among the 1264 patients at MCI stage, 61% converted to AD dementia (median time to conversion: 25 months). Among the 1142 patients with mild AD dementia, 59% converted to moderate/severe stage (median time: 23 months) and among the 1332 patients with moderate AD dementia, 23% converted to severe stage (Q3 time to conversion: 22 months). Among the studied factors, cardiovascular comorbidities, anxiety, social isolation, osteoporosis, and hearing disorders were identified as being associated with earlier conversion across stages. Symptomatic treatment i.e. cholinesterase inhibitors for AD was associated with later conversion from mild stage of dementia to moderate/severe stages. CONCLUSION: This study based on a machine learning approach allowed to identify potentially modifiable factors associated with conversion across AD stages for which timely interventions may be implemented to delay disease progression.

OBJECTIVES: The primary objective of the present study was to evaluate and compare the ability of eight nutrition-related tools to predict 1-year mortality in older patients with cancer. DESIGN, SETTING AND PARTICIPANTS: We studied older patients with cancer from the ELCAPA cohort and who had been referred for a geriatric assessment at one of 14 participating geriatric oncology clinics in the greater Paris area of France between 2007 and 2018. MEASUREMENTS: The studied nutrition-related tools/markers were the body mass index (BMI), weight loss (WL) in the previous 6 months, the Mini Nutritional Assessment, the Geriatric Nutritional Risk Index (GNRI), the Prognostic Nutritional Index, the Glasgow Prognostic Score (GPS), the modified GPS, and the C-reactive protein/albumin ratio. RESULTS: A total of 1361 patients (median age: 81; males: 51%; metastatic cancer: 49%) were included in the analysis. Most of the tools showed a progressively increase in the mortality risk as the nutrition-related risk category worsened (overall p-values <0.02 for all) after adjustment for age, outpatient status, functional status, severe comorbidities, cognition, mood, cancer treatment strategy, tumour site, and tumour metastasis. All the models were discriminant, with a C-index ranging from 0.748 (for the BMI) to 0.762 (for the GPS). The concordance probability estimate ranged from 0.764 (WL) to 0.773 (GNRI and GPS)). CONCLUSION: After adjustment for relevant prognostic factors, all eight nutrition-related tools/markers were independently associated with 1-year mortality in older patients with cancer. Depending on the time or context of the GA, physicians do not always have the time or means to perform and assess all the tools/markers compared here. However, even when some information is missing, each nutritional tool/marker has prognostic value and can be used in the evaluation.

OBJECTIVE: To assess the prognostic value of neurocognitive disorder (NCD) for 12 month-overall mortality in patients aged 70 or more with a solid cancer. DESIGN: prospective, observational, multicenter cohort. SETTING AND PARTICIPANTS: We analyzed data from the ELCAPA longitudinal multicenter observational cohort of patients aged 70 or over, referred for a geriatric assessment (GA) before a new cancer treatment modality between January 31st, 2007, and December 29th, 2017. We defined the baseline NCD in four classes: no NCD, mild NCD, moderate NCD, and major NCD, based on the Mini-Mental State Examination (MMSE) score, memory complaint, and the Instrumental Activities of Daily Living (IADL) score. STATISTICAL METHODS: We compared the baseline characteristics of patients according to NCD classes, globally and by pairs (with Bonferroni' correction). Prognosis value of NCD classes were analysed by using univariable and then multivariable 12 month survival analysis with age as time-variable and with and without adjustement for the treatment strategy (curative, palliative or exclusive supportive care). RESULTS: 2784 patients with solid-cancer were included, with a median [interquartile range] age of 82 [78;86]. 36% of the patients were free of NCD, 34% had a mild NCD, 17% had a moderate NCD, and 13% had a major NCD. We identified the following independent prognostic factors for 12 month-overall mortality: NCD (adjusted hazard ratio (aHR) [95% confidence interval (CI)] for a major NCD = 1.54 [1.19-1.98] (p < 0.001), type of cancer, metastatic status, inpatient consultation, poor general health (assessed as the level of fatigue and Eastern Cooperative Oncology Group performance status [ECOG-PS]), greater weight loss, palliative treatment, and exclusive supportive care. Additional adjustment for the treatment strategy did not greatly change the strength of the association of a major NCD with 12 month-overall mortality (HR [95%CI] = 1.78 [1.39-2.29] (p < 0.001). CONCLUSION: Our results suggest that the presence of a major NCD has direct prognostic value (independently of other geriatric factors, the type of cancer and the treatment strategy) in older patients with a solid cancer.

CONTEXT: More than half of new cancer cases occurred in older adults. Older patients with cancer are particularly at risk of physical, psycho-existential or socio-familial suffering as defined by the concept of Serious Health-related Suffering (SHS). OBJECTIVES: To assess the direct and indirect effects of physical, psycho-existential and socio-familial dimensions of suffering on cancer treatability, supportive care needs and 12-month mortality in older patients with cancer. METHODS: We included patients with cancer aged 70 years and over from the Elderly Cancer Patients cohort (ELCAPA, Ile-de-France), referred for geriatric assessment between 2007 and 2019 before cancer treatment. Structural equation modelling examined the direct and indirect relationships between SHS dimensions (latent variables), patients' characteristics (age, sex, tumor location and metastatic status, comorbidity, period of care), and outcomes. RESULTS: The analysis included 4,824 patients (mean age: 82.2 ± 4 years; women: 56%; main cancer sites: breast [22.3%], colorectal [15.2%], prostate [8.5%], and lung [6.8%]; metastatic cancer: 46%). Physical suffering had direct pejorative effects on cancer treatability, and mortality (standardized coefficient [SC]â¯=â¯0.12 [P<0.001], SCâ¯=â¯0.27 [P<0.001], respectively). Psycho-existential and socio-familial sufferings had indirect pejorative effects on survival through decreased cancer treatability (SCâ¯=â¯0.08 [P<0.001], SCâ¯=â¯0.03 [P<0.001], respectively). Psycho-existential dimension had the main direct effect size on supportive care needs (SCâ¯=â¯0.35 [P<0.001]) and was interrelated with physical suffering. CONCLUSION: Physical suffering has direct pejorative effect on survival. All dimensions indirectly decrease survival due to poorer cancer treatability. Our findings support concomitant management of physical and psycho-existential suffering.
RESUMEN
Due to the location and toxicity of treatments, head and neck cancer (HNC) has a major impact on quality of life (QoL). Objective: to assess the effects of geriatric-assessment (GA)-driven interventions on QoL over 2 years in older adults with HNC.EGeSOR was a randomized study of HNC patients aged ≥65, receiving a pretreatment GA, a geriatric intervention and follow-up (intervention) or standard of care (control). The primary endpoint was QoL score using the European Organisation for Research and Treatment of Cancer's (EORTC QLQ-C30) and HNC (QLQ-HN35) QoL questionnaires over 24 months.In total, 475 patients were included (median age: 75.3; women: 31%; oral cancer: 44%). QoL scores improved over 24 months with various trajectories, without significant differences between the groups. A total of 74% of patients (interventional group) did not receive the complete intervention. Cancer characteristics, functional status, and risk of frailty were associated with change in the Global Health Status QoL score.There is a need to develop an alternative model of implementation such as patient-centered health-care pathways.
