Cognition in Older Adults With Cancer Receiving Systemic Anti-Cancer Therapy (CORreCT)

February 25, 2026 updated by: Prof Andrew Davies, Our Lady's Hospice and Care Services

Evaluating Cognitive Trajectories in Older Adults With Cancer

The majority of cancer diagnoses occur in adults age 65 years and over. This population is also rapidly expanding. There is a growing need for increased understanding about the potential impact of various newer therapies on common geriatric impairments in this group.

The aim of this study is to examine how feasible it is to carry out a study of cognitive function in older adults (age 65+) who are newly commencing anti-cancer treatments, specifically 'immune checkpoint inhibitor' therapy, over time. Participants in the study undergo four tests of memory and concentration every six weeks for a six month period. Additionally, the researcher will gather information about the participants' non-cancer therapy medications, physical and psychological symptoms, day to day functioning and any changes to these factors over time.

The purpose of the study is to examine a) recruitment, retention and engagement of participants to study procedures; b) to gather preliminary information about cognitive function in older adults commencing immune checkpoint inhibitor treatments and potential associations with cognitive decline over time.

Study Overview

Status

Active, not recruiting

Detailed Description

Despite cognitive concerns being commonly described by many patients with cancer, the majority of literature focuses on the impact of chemotherapy and more recently, hormone therapies, on cognitive function. Immune checkpoint inhibitors have revolutionised the management of many cancer types, and their indications are continuing to expand. There is insufficient evidence in the literature regarding the impact of therapy on cognitive function, and particularly in older adult age groups, who may be more susceptible to the cognitive effects of treatments.

Research Hypothesis:

A significant proportion of older adults receiving ICIs have cognitive impairment at the time of cancer diagnosis and that cognition deteriorates in this cohort of adults over the course of their illness due to many factors.

Aim:

To evaluate trajectories of cognitive decline in older adults with cancer commencing ICI therapy over time and to examine associated factors which may influence the trajectory of cognitive decline in this population.

Study Design:

Feasibility Prospective Observational Study

Methodology:

Adults age 65+, newly commencing immune checkpoint inhibitor therapy recruited to this study undergo six-weekly assessments for a six month period. Each assessment includes a commonly used screening tool for mild cognitive impairment, examining global cognition - the Montreal Cognitive Assessment (MoCA); supplemented with 3 neuropsychological tests evaluating verbal learning and memory (Hopkins Verbal Learning Test - Revised), executive function (Controlled Oral Word Association Test) and executive function & processing speed (Trail-Making Test part A&B). These supplementary tests have been recommended by the International Cognition in Cancer Task force as minimum neuropsychological tests that should be included to homogenise research in this field.

Additional data is collected per participant regarding: education status, frailty status, performance status, non-cancer therapy prescriptions, physical and psychological symptoms, recent falls and hospitalisations.

The target recruitment sample is 30 patients, as this is a feasibility study.

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Exploratory Primary Endpoint
Time Frame: Following completion of primary endpoint (3 months)

The primary (exploratory) endpoint will be development or worsening of cognitive impairment at 3 months as defined by MOCA cut-offs for mild, moderate and severe cognitive impairment.

Age, education and sex-matched participant MOCA results from the Irish Longitudinal Study of Ageing (TILDA) will be used to provide 2 comparator groups in the analysis: a) age and sex-matched participants without cancer and b) age and sex-matched participants with cancer (i.e. an active cancer diagnosis or a diagnosis of cancer within 5 years prior to wave 6)

Following completion of primary endpoint (3 months)
Exploratory Secondary Endpoints
Time Frame: From baseline assessment (T0) to 6-month assessment (T4) i.e. at each 6-weekly assessment for a 6 month period from the time of baseline assessment.
Development or worsening of cognitive impairment (based on MOCA score) at all study time points (see above). Cognitive impairment is defined as a MOCA score of <26/30 based on the MoCA validation study. A change in MOCA score of 4 points or more indicates clinically significant change for an individual participant.
From baseline assessment (T0) to 6-month assessment (T4) i.e. at each 6-weekly assessment for a 6 month period from the time of baseline assessment.
Exploratory Secondary Endpoints
Time Frame: At primary endpoint (i.e. 3 months from time of study entry for each individual participant) (T2)
