Comparison of symptom clusters associated with fatigue in older and younger survivors of colorectal cancer.

PURPOSE: Cancer-related fatigue (CRF) is one of the most frequently reported symptoms in cancer survivors. To be able to optimally treat CRF, knowledge of symptoms that interact with CRF is helpful. During aging, changes occur in body composition with progressive deterioration in physiological functions and metabolic processes causing a decline of adaptive capacity. Therefore, symptoms caused by cancer and its treatment might coexist in different symptom clusters in older cancer survivors, compared to younger survivors. The purpose of this analysis was to identify and compare symptom clusters that include CRF between older and younger survivors of colorectal cancer (CRC). METHODS: Data were drawn from a cross-sectional study from the Netherlands Cancer Registry. In total, 1698 stage I and II CRC survivors diagnosed from 2000 to 2009 completed questionnaires on fatigue and psychological distress. Survivors were categorized in two groups based on age (≤65 versus >65 years) Symptom clusters were assessed using principal component analysis. A sensitivity analysis was performed on the results with categorical principal component analysis. RESULTS: In both age groups, three components including two symptom clusters were identified: an emotional symptom cluster containing anxiety, fatigue, and depression; a pain symptom cluster containing pain and insomnia; and a third component containing dyspnea only. CONCLUSIONS: Symptom clusters in survivors of CRC appear to be independent of age. In treating CRC survivors for fatigue, regardless of age, it is advisable to assess depression and anxiety and, if necessary, refer for further diagnosis and treatment.

The impact of comorbidity on Health-Related Quality of Life among cancer survivors: analyses of data from the PROFILES registry.

PURPOSE: The aim of this study was to assess the difference in explained variance of Health-Related Quality of Life (HRQoL) between comorbidity, sociodemographic characteristics and cancer characteristics. This association was assessed among thyroid cancer, colorectal cancer, and (non-)Hodgkin's lymphoma patients. METHODS: Data from three large population-based surveys on survivors of thyroid cancer, colorectal cancer, and (non-)Hodgkin's lymphoma were used. Cancer-specific HRQoL was assessed with the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) of which physical function, emotional function, fatigue, and pain were included in the analyses. Comorbidity was assessed using the Self-reported Comorbidity Questionnaire. The association between comorbidity and HRQoL was assessed with multivariate linear regression models. Semi-partial R (2) was reported to assess the amount of variance in HRQoL explained by comorbidity in comparison with sociodemographic and cancer characteristics. RESULTS: In total, 3,792 cancer survivors were included in this analysis. The variance in HRQoL subscales explained by comorbidity was higher compared with sociodemographic and cancer characteristics for physical function (11-17 vs. 2-4 and 1-2 %, respectively) and emotional function (7-17 vs. 1-3 and 1-3 %, respectively), regardless of cancer type. In addition, comorbidity explained 7-20 and 11-13 % of the variance in pain and fatigue, respectively, compared to 0-4 % for both sociodemographic and cancer characteristics. Osteoarthritis and back pain were strongly associated with physical function and pain, while depression was strongly associated with emotional function. Depression and back pain were strongly associated with fatigue. CONCLUSIONS: This study showed that comorbidity explained more variance in physical and emotional function, pain, and fatigue in comparison with sociodemographic and cancer characteristics in cancer survivors, regardless of cancer type. Our findings emphasize the importance of adjusting for the presence of comorbid diseases when assessing HRQoL in cancer survivors. IMPLICATION FOR CANCER SURVIVORS: Cancer survivors suffering from comorbid diseases experience lower levels of health-related quality of life. Clinicians should become more aware of the impact of comorbidity on HRQoL and provide necessary psychological support to assist self-management of comorbid diseases.

Quality of life of older rectal cancer patients is not impaired by a permanent stoma.

BACKGROUND: The current study was undertaken to investigate the impact of a stoma on the HRQL with a special focus on age. MATERIALS AND METHODS: Using the Eindhoven Cancer Registry, rectal cancer patients diagnosed between 1998 and 2007 in 4 hospitals were identified. All patients underwent TME surgery. Survivors were approached to complete the SF-36 and EORTC QLQ-C38 questionnaires. HRQL scores of the four groups, stratified by stoma status (stoma/no stoma) and age at operation (<70 and ≥ 70), were compared. The SF-36 and the QLQ-CR38 sexuality subscale scores of the survivors were compared with an age- and sex-matched Dutch norm population. RESULTS: Median follow-up of 143 patients was 3.4 years. Elderly had significantly worse physical function (p = 0.0003) compared to younger patients. Elderly (p = 0.005) and patients without a stoma (p = 0.009) had worse sexual functioning compared to younger patients and patients with a stoma. Older males showed more sexual dysfunction (p = 0.01) when compared to younger males. In comparison with the normative population, elderly with a stoma had worse physical function (p < 0.01), but slightly better mental health (p < 0.05). Elderly without a stoma had better emotional role function (p < 0.01), and younger patients had worse sexual functioning and enjoyment (both p < 0.0001). CONCLUSIONS: Older patients with a stoma have comparable HRQL to older patients without a stoma or the normative population, indicating the feasibility of a permanent stoma for elderly patients with a low situated rectal carcinoma. The negative impact of treatment on sexual functioning as found in the current study calls for further attention to alleviate this problem in sexually active patients.

Higher prevalence of sexual dysfunction in colon and rectal cancer survivors compared with the normative population: a population-based study.

BACKGROUND: To compare colorectal cancer survivors with a normative population regarding erectile dysfunction, ejaculation problems, dyspareunia, dry vagina, sexual functioning (SF) and enjoyment (SE). In addition, the sociodemographic, clinical and psychological correlates of (dys)function in survivors are examined. PATIENTS AND METHODS: The European Organisation for Research and Treatment of Cancer (EORTC) QLQ-CR38 sexuality subscales were completed by survivors (n=1371; response rate 82%), of which 1359 received surgical treatment and were included in the analysis. The normative population consisted of 400 participants (response rate 78%). RESULTS: Erectile problems were more often present in rectal cancer (54%) than colon cancer survivors (25%) and the normative population (27%; p<.0001). They also had more ejaculation problems (68%) than colon cancer survivors (47%; p<.001). Dry vagina was common in colon (28%) and rectal cancer survivors (35%), while the normative population scored lower (5%; p=.003). In addition, colon (9%) and rectal cancer survivors (30%) experienced more pain during intercourse than the normative population (0%; p=.001). SE for men was similar across groups, while women with colorectal cancer reported lower scores than the normative population. Higher age, being a woman, not having a partner, a low educational level, rectal cancer, depressive symptoms and fatigue were associated with lower SF. Lower SE was associated with higher age and being a woman, depressive symptoms and cardiovascular disease. CONCLUSION: SF was deteriorated in both sexes after cancer, which affected women's SE negatively. Attention towards sexual (dys)function in colorectal cancer survivors is needed.

Excess weight among colorectal cancer survivors: target for intervention.

BACKGROUND: Healthy lifestyle might improve outcome among colorectal cancer (CRC) survivors. In this study we investigated the proportion of survivors who meet recommended lifestyle and weight guidelines and compared this to the general population. Factors that predict current behaviour were also assessed. METHOD: A random sample of CRC survivors diagnosed between 1998 and 2007 were surveyed. Percentages of current smokers, alcohol consumers, excess weight and clustering of these variables were calculated. Using logistic regression we assessed demographical and clinical factors that predict current lifestyle and excess weight. RESULTS: We included 1349 (74% response rate) survivors in this study of whom only 8 and 16% of male and female survivors met the recommended lifestyle and body weight. Among male survivors up to 10% had at least two unhealthy lifestyle factors and among women, up to 19%. The proportion of smokers and those who had ever consumed alcohol was lower compared to the general population (13 vs. 31%, 82 vs. 86% respectively), but excess weight (BMI at least 25 kg/m(2)) was more prevalent among survivors (69 vs. 53% respectively). Having received chemotherapy was significantly associated with being overweight (adjusted odd ratio 1.5, 95% confidence interval 1.05-2.3). Younger patients, male gender and survivors of lower socioeconomic status were more likely to show non-compliance to healthy lifestyle recommendations. CONCLUSION: The observed clustering of unhealthy lifestyle warrants interventions targeting multiple behaviours simultaneously. Reducing excess weight should be one of the most important targets of interventions, particularly for males, those who had chemotherapy and survivors of lower socioeconomic status.
