Cancer mortality and competing causes of death in older adults with cancer: A prospective, multicentre cohort study (ELCAPA-19)

Association of depression with all-cause and cancer-specific mortality in older adults with cancer: Systematic review, meta-analysis, and meta-regression

INTRODUCTION

The incidence and mortality of cancer is increasing worldwide with studies reporting that cumulative risk of cancer rises as age increases. Against the backdrop of the increasing prevalence of cancer amongst older patients, we conducted a systematic review and meta-analysis examining the depression-mortality relationship in older adults with cancer (OAC).

MATERIALS AND METHODS

This PRISMA-adherent systematic review involved a systematic search of PubMed, Medline, EMBASE, and PsycINFO for prospective and retrospective cohort studies comparing the risk of all-cause and cancer-related mortality among OAC with depression. Random effects meta-analyses and meta-regressions were used for the primary analysis.

RESULTS

From 5,280 citations, we included 14 cohort studies. Meta-analyses of hazard ratios (HRs) showed an increased incidence of all-cause mortality in OAC with depression (pooled HR: 1.40; 95% confidence interval [CI]: 1.25, 1.55). Subgroup analyses of other categorical study-level characteristics were insignificant. While risk of cancer-related mortality in OAC with depression was insignificantly increased with a pooled HR of 1.21 (95% CI: 0.98, 1.49), subgroup analysis indicated that risk of cancer-related mortality in OAC with depression significantly differed with cancer type. Our systematic review found that having fewer comorbidities, a higher education level, greater socioeconomic status, and positive social supportive factors lowered risk of all-cause mortality in OAC with depression.

DISCUSSION

Depression in OAC significantly increases risk of all-cause mortality and cancer-related mortality among different cancer types. It is imperative for healthcare providers and policy makers to recognize vulnerable subgroups among older adults with cancer to individualize interventions.

Hospital-based palliative care referrals: determinants in older adults with cancer

OBJECTIVES

Early palliative care improves the quality of life of older patients with cancer. This work aimed to analyse the effect of sociodemographic, geriatric, and tumour-related determinants on hospital-based palliative care (HPC) referral in older patients with cancer, taking into account competing risk of death.

METHODS

Older adults with diagnosed cancer from 2014 to 2018 according to the general cancer registry of Gironde (French department) were identified in three population-based cohorts on ageing (PAQUID, 3C - Three City, AMI). Cause-specific Cox models focused on 10 usual determinants in geriatric oncology and palliative care: age, gender, living alone, place of residency, tumour prognosis, activities of daily living (ADL) and instrumental-ADL (IADL) limitations, cognitive impairment, depressive disorders, and polypharmacy.

RESULTS

131 patients with incident cancer (mean age: 86.2 years, men: 62.6%, poor cancer prognosis: 32.8%) were included, HPC occurring for 26 of them. Unfavourable cancer prognosis was a key determinant for HPC referral (HR 7.02, 95% CI 2.86 to 17.23). An altered IADL score was associated with precocious (first year) referral (HR 3.21, 95% CI 1.20 to 8.64, respectively). Women had a higher rate immediately (first week) after diagnosis (HR 8.64, 95% CI 1.27 to 87.27).

CONCLUSIONS

Cancer prognosis, functional decline and gender are independent factors of HPC referral in older patients with cancer. These findings may help for a better anticipation of the healthcare pathway.
