Illness perceptions are associated with mortality among 1552 colorectal cancer survivors:A study from the population-based PROFILES registry

Purpose Cancer survivors construct perceptions of illness as a (mal)adaptive mechanism. These perceptions motivate/drive subsequent self-management behaviors toward symptoms and treatment that influence health outcomes. Negative illness perceptions have been associated with increased mortality in other chronically ill groups. However, this association is under-researched in cancer survivors. We aimed to explore the association between illness perceptions and mortality in stage I–III progression-free colorectal cancer (CRC) survivors. Methods We used data from the population-based Patient Reported Outcomes Following Initial treatment and Long Term Evaluation of Survivorship (PROFILES) registry of two CRC survivorship studies conducted in 2009 and 2010. We accessed clinical data from the Netherlands Cancer Registry, and mortality data from municipal personal records database. Follow-up was until 31 December 2014. Survivors (n = 1552) completed the Brief Illness Perception Questionnaire. Cox proportional hazard models estimated the association between illness perceptions and mortality. Results Negative illness perceptions on consequences (adjusted hazard ratio (HRadj) 1.60, 95 % confidence interval (CI) 1.14–2.25) and emotion (HRadj 1.65, 95 % CI 1.18–2.31) were associated with higher mortality, after adjusting for demographic, clinical, and lifestyle factors. Smoking and inadequate physical activity were independently associated with mortality for all Brief Illness Perception Questionnaire (BIPQ) dimensions. Conclusions Survivors’ perceptions of their illness are important as these perceptions may influence health outcomes during survivorship period. Clinical practice needs to identify and address maladaptive illness perceptions to support more adaptive self-management behaviors and enhance survivorship. Implications for cancer survivors Cancer survivors may benefit from interventions that address potentially maladaptive perceptions and encourage more adaptive self-management behaviors

Prospectively measured lifestyle factors and BMI explain differences in health-related quality of life between colorectal cancer patients with and without comorbid diabetes

Purpose This study aimed to assess the longitudinal association between lifestyle factors, body mass index (BMI), and health-related quality of life (HRQoL) among colorectal cancer patients with (CRCDM+) and without diabetes (CRCDM−). Methods Data from a longitudinal study among CRC patients diagnosed between 2000 and 2009 were used. Clinical characteristics were retrieved from the Netherlands Cancer Registry and questionnaires were sent in 2010, 2011, and 2012 using the Patient Reported Outcomes Following Initial Treatment and Long term Evaluation of Survivorship (PROFILES) registry. Lifestyle (including moderate-to-vigorous physical activity (MVPA), smoking and alcohol use), BMI, diabetes status, and HRQoL were assessed in the questionnaire. Results One thousand seven hundred thirty-nine (49 %) patients responded to ≥2 questionnaires, of whom 126 CRCDM+ and 789 CRCDM− patients were included. CRCDM+ patients had a higher BMI (29.1 ± 4.2 vs. 26.4 ± 3.7 kg/m2), whereas the number of alcohol users was lower (50 vs. 70 %, p value <0.0001) among CRCDM+ as compared to CRCDM− patients. Analyses adjusted for sociodemographic and cancer characteristics showed that CRCDM+ patients reported statistically significantly lower physical function (beta = -5.76; SE = 1.67), global QoL (beta = -4.31; SE = 1.48), and more symptoms of fatigue (beta = 5.38; SE = 1.95) than CRCDM− patients. However, these effects disappeared after adjustments for lifestyle factors and BMI which were all significant predictors of HRQoL. Additional adjustment for comorbidity further attenuated the main effect of DM on HRQoL. Conclusions Diabetes was not independently associated with HRQoL but deteriorated HRQoL among CRCDM+ patients seem to be explained by an unhealthier lifestyle and other comorbid conditions. Moreover, residual confounding cannot be ruled out.KeywordsColorectal cancer, Diabetes, Lifestyle, Health-related quality of lif

Anxiety and depression mediate the association between chemotherapy-induced peripheral neuropathy and fatigue:Results from the population-based PROFILES registry

Objective Chemotherapy‐induced sensory peripheral neuropathy (CIPN) is common among colorectal cancer (CRC) survivors. The aim of this study was to examine whether CIPN is associated with both psychological distress (ie, anxiety and depression) and fatigue and whether the relationship between CIPN and fatigue can (partly) be explained by psychological distress. Methods All CRC survivors diagnosed between 2000 and 2009 as registered by the population‐based Netherlands Cancer Registry (Eindhoven region) were eligible for participation. Chemotherapy‐treated survivors completed questions on CIPN (EORTC QLQ‐CIPN20), psychological distress (HADS), and fatigue (FAS) on average 5.6 years after diagnosis. Simple and multiple mediation analyses were performed to examine anxiety and depression as possible mediators in the association between CIPN and fatigue. Results Survivors with high (ie, upper 30% of scores) CIPN (n = 172) reported more anxiety and depressive symptoms and more fatigue compared with those with low CIPN (n = 299). Furthermore, among survivors with high CIPN, those who were anxious, depressed, or both reported more fatigue compared with those without psychological distress. These differences were clinically relevant. Finally, mediation analyses showed that while CIPN was directly associated with fatigue, the relationship between CIPN and fatigue was also significantly mediated by both anxiety and depression. Conclusions CRC survivors with high CIPN report more fatigue, especially those who are also anxious and/or depressed. More research is needed on the direction of the relationship between CIPN, psychological distress, and fatigue. For now, the treatment of fatigue should also focus on addressing psychological distress, as treating fatigue alone might not be sufficient

Trends in overall survival and treatment patterns in two large population-based cohorts of patients with breast and colorectal cancer

Previous studies showed substantial improvement of survival rates in patients with cancer in the last two decades. However, lower survival rates have been reported for older patients compared to younger patients. In this population-based study, we analyzed treatment patterns and the survival of patients with breast cancer (BC) and colorectal cancer (CRC). Patients with stages I- III BC and CRC and diagnosed between 2003 and 2012 were selected from the Netherlands Cancer Registry (NCR). Trends in treatment modalities were evaluated with the Cochran-Armitage trend test. Trends in five-year overall survival were calculated with the Cox hazard regression model. The Ederer II method was used to calculate the five-year relative survival. The relative excess risk of death (RER) was estimated using a multivariate generalized linear model. During the study period, 98% of BC patients aged <75 years underwent surgery, whereas for patients ≥75 years, rates were 79.3% in 2003 and 66.7% in 2012 (p < 0.001). Most CRC patients underwent surgery irrespective of age or time period, although patients with rectal cancer aged ≥75 years received less surgery or radiotherapy over the entire study period than younger patients. The administration of adjuvant chemotherapy increased over time for CRC and BC patients, except for BC patients aged ≥75 years. The five-year relative survival improved only in younger BC patients (adjusted RER 0.95-0.96 per year), and was lower for older BC patients (adjusted RER 1.00, 95% Confidence Interval (CI) 0.98- 1.02, and RER 1.00; 95% CI 0.98-1.01 per year for 65-74 years and ≤75 years, respectively). For CRC patients, the five-year relative survival improved over time for all ages (adjusted RER on average was 0.95 per year). In conclusion, th

Changes in hospital variation in the probability of receiving treatment with curative intent for esophageal and gastric cancer

Background: Previous studies describe a large variation in the proportion of patients undergoing treatment with curative intent for esophageal (EC) and gastric cancer (GC). Since centralization of surgical care was initiated and more awareness regarding hospital practice variation was potentially present, we hypothesized that hospital practice variation for potentially curable EC and GC patients changed over time. Methods: Patients with potentially curable EC (n = 10,115) or GC (n = 3988) diagnosed between 2012–2017 were selected from the Netherlands Cancer Registry. Multilevel multivariable logistic regression was used to analyze the differences in the probability of treatment with curative intent between hospitals of diagnosis over time, comparing 2012−2014 with 2015−2017. Relative survival (RS) between hospitals with different probabilities of treatment with curative intent were compared. Results: The range of proportions of patients undergoing treatment with curative intent per hospital of diagnosis for EC was 45–95 % in 2012−2014 and 54–89 % in 2015−2017, and for GC 52–100 % and 45–100 %. The adjusted variation declined for EC with Odds Ratios ranging from 0.50 to 1.72 between centers in the first period to 0.70–1.44 in the second period (p < 0.001) and did not change for GC (O

Nationwide trends in incidence, treatment and survival of pancreatic ductal adenocarcinoma

Background: In recent years, new treatment options have become available for pancreatic ductal adenocarcinoma (PDAC) including 5-fluorouracil, leucovorin, irinotecan and oxaliplatin. The impact hereof has not been assessed in nationwide cohort studies. This population-based study aimed to investigate nationwide trends in incidence, treatment and survival of PDAC. Materials and methods: Patients wi

The contribution of dairy products to micronutrient intake in the Netherlands

Objective: To assess the contribution of dairy products to the intake of various vitamins and minerals in several life stages in the Dutch population. Method: Data from 3 Dutch Food Consumption Surveys and the Leiden Longevity Study were used to estimate the contribution of dairy products—as percentage of total intake—to the intake of iron, copper, selenium, zinc, calcium, folic acid, vitamin D, vitamin C, and vitamin B12. Results: In young children, dairy products contributed substantially to the intake of calcium (73%), selenium (21%), iron (8%), zinc (39%), copper (12%), folic acid (24%), vitamin C (18%), vitamin D (16%), and vitamin B12 (58%). Of all dairy products, milk contributed the most to the intake of these nutrients. In adults and elderly subjects, the contribution of dairy products to total micronutrient intake was 65%–68% for calcium, 18%–19% for selenium, 3%–4% for iron, 28%–31% for zinc, 6%–7% for copper, 17%–19% for folic acid, 10%–14% for vitamin C, 11%–16% for vitamin D, and 44%–46% for vitamin B12. Milk as well as cheese contributed the most to the intake of these nutrients. Conclusions: Dairy products are an important source of vitamins and minerals in the Dutch population. Dairy products, especially milk and cheese, contribute substantially to the intake of calcium, selenium, zinc, and vitamin B1

Colorectal cancer, diabetes and survival: Epidemiological insights

Colorectal cancer (CRC) patients with pre-existing diabetes have significantly lower rates of overall survival compared with patients without diabetes. Against this backdrop, the American Diabetes Association and American Cancer Society in 2010 reviewed the scientific literature concerning diabetes and cancer. One of the key issues identified for further investigation was the need for a better understanding of whether diabetes influences cancer prognosis above and beyond the prognosis conferred by each disease state independently. Whether the worsened survival of CRC patients with diabetes could be explained by less favourable patient-, tumour- and treatment-related characteristics has also been evaluated in numerous recent studies. However, as most studies did not account for all the various potential confounders, such as cancer stage, comorbidities and body mass index (ME) in their analyses, the current evidence for the association between diabetes and survival in CRC patients remains inconclusive. Nevertheless, based on multiple examples in the literature, the present review demonstrates that diabetes affects the presentation of CRC as well as its treatment and outcome, which may then result in lower overall rates of survival in patients with, compared to those without, diabetes.
