Physical functional limitations and psychological distress in people with and without colorectal cancer: findings from a large Australian study

Association of cancer diagnosis with disability status among older survivors of colorectal cancer: a population-based retrospective cohort study

Background

Older cancer survivors likely experience physical function limitations due to cancer and its treatments, leading to disability and early mortality. Existing studies have focused on factors associated with surgical complications and mortality risk rather than factors associated with the development of poor disability status (DS), a proxy measure of poor performance status, in cancer survivors. We aimed to identify factors associated with the development of poor DS among older survivors of colorectal cancer (CRC) and compare poor DS rates to an age-sex-matched, non-cancer cohort.

Methods

This retrospective cohort study utilized administrative data from the Texas Cancer Registry Medicare-linked database. The study cohort consisted of 13,229 survivors of CRC diagnosed between 2005 and 2013 and an age-sex-matched, non-cancer cohort of 13,225 beneficiaries. The primary outcome was poor DS, determined by Davidoff's method, using predictors from 12 months of Medicare claims after cancer diagnosis. Multivariable Cox proportional hazards regression was used to identify risk factors associated with the development of poor DS.

Results

Among the survivors of CRC, 97% were 65 years or older. After a 9-year follow-up, 54% of survivors of CRC developed poor DS. Significant factors associated with future poor DS included: age at diagnosis (hazard ratio [HR] = 3.50 for >80 years old), female sex (HR = 1.50), race/ethnicity (HR = 1.34 for Hispanic and 1.21 for Black), stage at diagnosis (HR = 2.26 for distant metastasis), comorbidity index (HR = 2.18 for >1), and radiation therapy (HR = 1.21). Having cancer (HR = 1.07) was significantly associated with developing poor DS in the pooled cohorts; age and race/ethnicity were also significant factors.

Conclusions

Our findings suggest that a CRC diagnosis is independently associated with a small increase in the risk of developing poor DS after accounting for other known factors. The study identified risk factors for developing poor DS in CRC survivors, including Hispanic and Black race/ethnicity, age, sex, histologic stage, and comorbidities. These findings underscore the importance of consistent physical function assessments, particularly among subsets of older survivors of CRC who are at higher risk of disability, to prevent developing poor DS.

Resilience process in individuals with colorectal cancer: a qualitative study

PURPOSE

Resilience is a positive outcome in giving individuals strength to adapt to cancer and have better various aspects of health-related quality of life. However, research focusing on resilience in relation to colorectal cancer (CRC) is limited. Therefore, the aim of this study was to explore the process of resilience in individuals with CRC.

METHOD

Sixteen individuals diagnosed with stage Ι to III CRC within the last five years were recruited from a CRC surgical outpatient department in a medical center in Northern Taiwan. Semi-structured interviews were used to explore the resilience process of living with CRC. Recorded interviews were transcribed verbatim and were analyzed using modified grounded theory.

FINDINGS

Resilience is a dynamic three-phase process, including impact of CRC, adaptation or maladaptation following CRC, and growth from CRC experience. Resilience strategies (i.e., attitude adjustment, developing personal strategies to conquer CRC and side effects, setting new goals in life, and viewing death as a normal process), avoidance behaviors, and passive waiting strategy were shown across the resilience process.

CONCLUSIONS

All individuals showed negative impacts during CRC diagnosis and treatments, but some individuals used the resilience strategies in helping to promote positive adjustment and redirect to develop their resilience process. Furthermore, resilient and maladaptive individuals may change the situation depending on which strategies are used and on the progression of CRC because resilience is dynamic. Oncology clinicians should help individuals use resilience strategies to smoothly go through the resilience process.

Correlates of Psychological Distress in Patients With Cancer at a Psycho-oncology Clinic

BACKGROUND

Patients with cancer experience significant psychological distress. Most studies investigated individual risk factors for distress in their respective treatment setting, which limit generalizability of results or comparison of relative importance.

OBJECTIVE

To investigate the relation between psychological distress in patients referred to a psycho-oncology clinic and its correlates in a comprehensive manner.

METHOD

Medical charts of patients who visited the psycho-oncology clinic at a tertiary hospital from May 2019 to May 2020 were reviewed. Demographic, cancer-related, and psychiatric factors; health-related quality of life; and somatic pain were investigated. The Hospital Anxiety and Depression Scale, item 9 on the Patient Health Questionnaire-9, Functional Assessment of Cancer Therapy-General, Present Pain Intensity, and Distress Thermometer were measured at the index visit. Simple and multiple linear regression analyses were performed with the Distress Thermometer score as a dependent variable.

RESULTS

A total of 454 patients were included. The univariate analyses showed age and physical, emotional, and functional well-being scores on the Functional Assessment of Cancer Therapy-General were negatively associated with the Distress Thermometer scores, while female genital cancer, advanced disease, recent radiotherapy, the Hospital Anxiety and Depression Scale score, and the Present Pain Intensity score showed a positive relation. After adjusting for all other variables, female genital cancer (P = 0.027), anxiety subscale of the Hospital Anxiety and Depression Scale (P < 0.001), the Present Pain Intensity (P = 0.002), and physical (P < 0.001) and functional (P = 0.019) well-being subscales of the Functional Assessment of Cancer Therapy-General remained significant.

CONCLUSIONS

Patients with cancer who visited a psycho-oncology clinic experienced more distress if they had female genital cancer, low health-related quality of life score, severe anxiety, or somatic pain.

Disability, psychological distress and quality of life in relation to cancer diagnosis and cancer type: population-based Australian study of 22,505 cancer survivors and 244,000 people without cancer

BACKGROUND

Improved survival means that cancer is increasingly becoming a chronic disease. Understanding and improving functional outcomes are critical to optimising survivorship. We quantified physical and mental health-related outcomes in people with versus without cancer, according to cancer type.

METHODS

Questionnaire data from an Australian population-based cohort study (45 and Up Study (n = 267,153)) were linked to cancer registration data to ascertain cancer diagnoses up to enrolment. Modified Poisson regression estimated age- and sex-adjusted prevalence ratios (PRs) for adverse person-centred outcomes-severe physical functional limitations (disability), moderate/high psychological distress and fair/poor quality of life (QoL)-in participants with versus without cancer, for 13 cancer types.

RESULTS

Compared to participants without cancer (n = 244,000), cancer survivors (n = 22,505) had greater disability (20.6% versus 12.6%, respectively, PR = 1.28, 95%CI = (1.25-1.32)), psychological (22.2% versus 23.5%, 1.05 (1.02-1.08)) and poor/fair QoL (15.2% versus 10.2%; 1.28 (1.24-1.32)). The outcomes varied by cancer type, being worse for multiple myeloma (PRs versus participants without cancer for disability 3.10, 2.56-3.77; distress 1.53, 1.20-1.96; poor/fair QoL 2.40, 1.87-3.07), lung cancer (disability 2.81, 2.50-3.15; distress 1.67, 1.46-1.92; poor/fair QoL 2.53, 2.21-2.91) and non-Hodgkin's lymphoma (disability 1.56, 1.37-1.78; distress 1.20, 1.05-1.36; poor/fair QoL 1.66, 1.44-1.92) and closer to those in people without cancer for breast cancer (disability 1.23, 1.16-1.32; distress 0.95, 0.90-1.01; poor/fair QoL 1.15, 1.05-1.25), prostate cancer (disability 1.11, 1.04-1.19; distress 1.09, 1.02-1.15; poor/fair QoL 1.15, 1.08-1.23) and melanoma (disability 1.02, 0.94-1.10; distress 0.96, 0.89-1.03; poor/fair QoL 0.92, 0.83-1.01). Outcomes were worse with recent diagnosis and treatment and advanced stage. Physical disability in cancer survivors was greater in all population subgroups examined and was a major contributor to adverse distress and QoL outcomes.

CONCLUSIONS

Physical disability, distress and reduced QoL are common after cancer and vary according to cancer type suggesting priority areas for research, and care and support.
