Prevalence and assessment tools of cancer-related cognitive impairment in lung cancer survivors: a systematic review and proportional meta-analysis.

ABSTRACT:

Purpose

Cancer-related cognitive impairment (CRCI) is a significant risk factor influencing the quality of life in lung cancer survivors. No absolute assessment tool has been confirmed to assess CRCI in lung cancer survivors. This review was undertaken to pool the overall prevalence of CRCI and to summarize the assessment tools in assessing CRCI among lung cancer survivors.

Methods

PubMed, Cochrane Library, Embase, CINAHL, and CNKI were searched to retrieve articles reported CRCI prevalence. Summary prevalence estimates were pooled using a random effects model, along with corresponding 95% prediction intervals (PIs). The Freeman-Tukey double arcsine transformation of proportions was incorporated in the analysis. Additionally, subgroup analysis, meta-regression, and leave-one-out analysis were performed.

Results

A total of 12 studies, involving 1934 survivors, were included in the review. All of these studies were found to have a low risk of bias in terms of their methodological quality. Four studies (33.3%) utilized the International Cognition and Cancer Task Force (ICCTF) criteria to identify CRCI through neuropsychological tests. The pooled prevalence rate of CRCI was found to be 26% (95% PI, 16-37%), I² = 95.97%. The region in which the studies were conducted was identified as a significant factor contributing to this heterogeneity (p = 0.013). No indication of small-study effects was found (Egger's test: p = 0.9191).

Conclusion

This review provides an overview of CRCI prevalence and assessment tools in lung cancer survivors. The findings can serve as epidemiological evidence to enhance clinicians' and researchers' understanding of early detection and assessment.

Project description:BackgroundOur longitudinal study reported cognitive impairment in 43% of people following diagnosis of localised colorectal cancer (CRC) versus 15% in healthy controls (p < 0.001) and 50% versus 13% 1-2 years later (p < 0.001). Here we evaluate cognitive function and neuroimaging in a subgroup at long-term follow-up.Patients and methodsCancer-free Australian participants in the study, and controls, completed cognitive and functional assessments. Neuroimaging was optional. Blood tests included inflammatory markers, clotting factors, sex hormones and apolipoprotein E genotype. The primary endpoint was demographically and practice effect-corrected cognitive scores comparing CRC survivors with controls over time examined using a linear mixed model, adjusted for baseline performance. Secondary endpoints included cognitive impairment rate using the Global Deficit Score [GDS > 0.5], Functional Deficit Score, blood results and neuroimaging.ResultsThe study included 25 CRC survivors (60% men, median age 72) at mean 9 years after baseline (9 received adjuvant chemotherapy) and 25 controls (44% men, median age 68) at mean 6 years after baseline. There were no significant differences in cognitive scores or proportion with cognitive impairment (16 vs. 8%) between survivors and controls and no evidence of accelerated ageing in CRC survivors. Baseline cognitive performance predicted for subsequent cognitive function. There were no differences in functional tests or blood tests between groups. In 18 participants undergoing neuroimaging, 10 CRC survivors had higher myoinositol levels than 8 controls, and lower volume in the right amygdala and caudate and left hippocampal regions.ConclusionsThere was no difference in cognitive capacity and function between CRC survivors and controls 6-12 years after diagnosis. Differences in neuroimaging require confirmation in a larger sample.Highlights• No evidence of long term cognitive impairment in colorectal cancer survivors compared to controls 6-12 years after diagnosis • No evidence of accelerated cognitive ageing in colorectal cancer survivors • No evidence of long-term functional impairment in colorectal cancer survivors.

Project description:PurposeUp to 70% of survivors report cognitive symptoms after chemotherapy. We compared two cognitive rehabilitation programs to a control group in cancer survivors.MethodsStudy population were adult cancer survivors with cognitive symptoms 6-60 months after adjuvant chemotherapy. Participants randomised to: Attention Process Training (APT), Compensatory Strategy Training (CST), or control group. Active interventions comprised 6-week, 2-h/week small group sessions.Assessmentspre- and post-intervention, 6- and 12-months later. Primary outcome was change in cognitive symptoms (FACT-COG-PCI subscale) between baseline and post-intervention. Secondary endpoints included objective neuropsychological performance, Functional Impact Assessment (FIA), patient-reported outcome measures, and associations. Analyses were on an intention-to-treat basis. Analysis of covariance mixed models were used for continuous outcomes.ResultsSixty-five participants were randomised (APT n = 21; CST n = 24; controls n = 20): 94% breast cancer, median age 54. Median time since chemotherapy 20.7 months. FACT-COG-PCI, clinical neuropsychological T-scores, and FIA improved in all groups over time, but no significant differences between arms. On mean neuropsychological T-scores 19/65 (29%) were impaired at baseline; post-intervention impairment controls 31.3%, CST 16.7%, APT 20.0%. On FIA at baseline, nine were impaired; this decreased to three post-intervention (one/group). FACT-COG-PCI was weakly associated with neuropsychological tests (rho = 0.24, p = 0.051) at baseline, and had no association with FIA. Neuropsychological total mean T-score was moderately positively associated with FIA (rho = 0.37, p = 0.003).ConclusionThere were no significant differences between intervention groups and controls using linear mixed models adjusted for baseline scores.Implications for cancer survivorsCognitive symptoms and neuropsychological test scores improve over time.

Project description:ObjectiveCognitive impairment negatively affects some cancer survivors who have completed chemotherapy; however, factors underlying this cognitive impairment remain poorly understood. We aimed to investigate (1) the relative importance of demographics, medical, and psychological characteristics associated with cognitive impairment and (2) the specific variables associated with cognitive impairment in adult cancer survivors who completed adjuvant chemotherapy.MethodsWe performed post hoc analyses of baseline data from early-stage cancer survivors with cognitive complaints who received adjuvant chemotherapy 0.5-5 years earlier and volunteered for a trial designed to improve cognition. The primary outcome of self-reported cognitive impairment was measured using a questionnaire; secondary outcome of objective cognitive impairment was measured using a computerized neuropsychological test battery. Hierarchical linear regression determined the relative importance of demographics, medical, and psychological characteristics in associations with both self-reported and objective cognitive impairment.ResultsThe sample was 95% female and 89% breast cancer patients. The final model accounted for 33% of variation in self-reported cognitive impairment (n = 212, demographics 5%, medical 3%, and psychological 25%), with fatigue and stress as significant individual correlates (p values ≤ 0.0001). For the secondary analysis, the final model accounted for 19% of variation in objective cognitive impairment (n = 206, demographics 10%, medical 5%, and psychological 4%), with age, smoking history, and number of chemotherapy cycles as significant individual correlates.ConclusionWe found that psychological characteristics are more important than demographic and medical characteristics in self-reported cognitive impairment, whereas other characteristics are more important in objective cognitive impairment. This suggests clinicians should investigate possible psychological problems in cancer survivors who self-report cognitive impairment.
