Optimizing diet and nutrition for cancer survivors: A review

Determinants of sleep quality in 5835 individuals living with and beyond breast, prostate, and colorectal cancer: a cross-sectional survey

PURPOSE

The present study aimed to quantify the level of sleep problems in 5835 breast, prostate, and colorectal cancer survivors, and explore a number of potential determinants of poor sleep quality in the present sample. BMI, diet, and physical activity were of particular interest as potential determinants.

METHODS

Participants who completed the 'Health and Lifestyle after Cancer' survey were adults who had been diagnosed with breast, prostate, or colorectal cancer (mean time since cancer diagnosis was 35.5 months, SD=13.56). Sleep quality was assessed using the Pittsburgh Sleep Quality Index. BMI was calculated from self-reported height and weight. Participants were categorised as meeting/not meeting the World Cancer Research Fund (WCRF) recommendations for fibre, fruit and vegetables, added sugar, red meat, processed meat, fat, alcohol, and physical activity. Analyses accounted for demographic and clinical factors.

RESULTS

Fifty-seven percent of those with sleep data were classified as poor sleepers (response rate 79%). Being female, having a higher number of cancer treatments, more comorbid conditions, and being more anxious/depressed increased the odds of being a poor sleeper. After adjustment for these factors, there were no associations between diet/alcohol/physical activity and sleep. However, BMI was associated with sleep. Individuals in the overweight and obese categories had 22% and 79% higher odds of being poor sleepers than individuals in the underweight/healthy weight category, respectively.

CONCLUSIONS

The findings suggest that there may be a need to develop sleep quality interventions for cancer survivors with obesity. Even after adjustment for multiple clinical and demographic factors, BMI (particularly obesity) was associated with poor sleep. Thus, researchers and health professionals should find ways to support individuals with overweight and obesity to improve their sleep quality.

IMPLICATIONS FOR CANCER SURVIVORS

The present findings highlight that poor sleep is a common issue in cancer survivors. Interventions seeking to improve outcomes for cancer survivors over the longer term should consider sleep quality.

Post-traumatic growth 5 years after cancer: identification of associated actionable factors

BACKGROUND

The number of cancer survivors is growing increasingly worldwide. The long-term negative consequences of the disease are now better known. Cancer may also foster positive outcomes. Some survivors consider life after cancer as the start of a new life and experience positive changes called post-traumatic growth (PTG) measured by a scale developed by Tedeschi and Calhoun.

OBJECTIVE

The purpose of this article was to explore actionable factors affecting PTG, particularly those in relation with health care management and those that reflected health behavior changes.

METHODS

This study included the 1,982 participants in the VICAN cohort who responded to the questionnaire on living conditions 2 and 5 years after diagnosis. Factors associated with a moderate or high PTG (score ≥ 63) were identified using logistic regressions.

RESULTS

Factors positively associated with moderate or high PTG were being satisfied with the time spent by health care team on information (OR:1.35 [1.08;1.70]), increased physical activity (OR:1.42 [1.04;1.95]) and healthier diet (OR:1.85 [1.44;2.36]) since diagnosis, and having benefited from psychological support at diagnosis (OR:1.53 [1.16;2.01]).

CONCLUSION

High PTG is positively associated with health behavior and time spent on information. Our findings suggest that appropriate clinical and educational interventions can help foster growth after the experience of cancer. Even if we do not know what causes what, it is admitted that the interventions leading to an increase of physical activity, for example, are good from all points of view.

A comparative analysis of type 2 diabetes management quality indicators in cancer survivors

Objective

This study aimed to assess indicators of type 2 diabetes mellitus (DM) management, including adequate DM control, and treatment rates, in cancer survivors according to the time of DM diagnosis and to compare them with the DM management indicators of a non-cancer control group.

Methods

We used the 2013–2019 data of the Korea National Health and Nutrition Examination Survey for this study. To compare their adequate DM control, and treatment rates, we identified 4918 patients with type 2 DM aged ≥ 30 years and classified them into pre-existing diabetes, pre-existing cancer, and diabetes without cancer groups. Predictors of adequate glycemic control and diabetes treatment were analyzed using binary logistic regression.

Results

Diabetes without cancer group had higher fasting blood glucose and glycosylated hemoglobin A1c levels and lower adequate glycemic control than did the other two groups. The preexisting cancer group had low treatment rates. After adjusting for age, gender, employment status, and duration of diabetes, the preexisting cancer group had 0.51-fold lower odds of receiving treatment, such as insulin injection or oral diabetes medications, than the other two groups (adjusted odds ratio, 0.50; 95% confidence interval, 0.38–0.66)

Conclusions

Cancer survivors had lower fasting glucose and HbA1c than those with diabetes without cancer. However, as a result of the sub-analysis, the treatment rate of the pre-existing cancer group was significantly lower than that of diabetes without cancer. Based on these results, cancer survivors’ care-related healthcare workers should be aware of the need for monitoring blood sugar even in cancer survivors without underlying diabetes mellitus and pay more attention to early detection and active treatment of diabetes.

Health-related quality of life among cervical cancer survivors at a tertiary hospital in Ghana

Introduction

Cervical cancer is the second most common female cancer in Ghana. The disease and its treatment significantly affect survivors’ health-related quality of life (HRQoL). We determined the overall quality of life (QoL) and identified its predictors among cervical cancer survivors after treatment.

Materials and methods

A hospital-based cross-sectional analytical study was conducted on 153 disease-free cervical cancer survivors who completed curative treatment between January 2004 and December 2018 at Komfo Anokye Teaching Hospital (KATH) in Kumasi, Ghana. We used the European Organization for Research and Treatment of Cancer core-30 item (EORTC QLQ-C30) and cervical cancer module (EORTC QLQ-CX24) to assess the survivors’ overall QoL. QoL domain scores were dichotomised as affected or unaffected by disease and its treatment. Significant differences between the affected and unaffected groups within each QoL domain were determined using the student T-test. We used Kruskal-Wallis and Dunn’s tests to examine the difference in QoL domains between treatment types, with significance based on Bonferroni corrections. Multivariable logistic regression was performed to identify predictors of overall QoL. A p-value of less than 0.05 was considered statistically significant.

Results

One hundred and fifty-three (153) women having a mean age of 58.3 (SD 11.4) years were studied. The overall QoL score was 79.6 (SD 16.0), and 74.5% of survivors reported good QoL score within the median follow up time of 41.8 months (interquartile range [IQR], 25.5–71.1 months) after cervical cancer diagnosis. Although the majority (66.0–84.3%) of the QoL functioning scale were unaffected, about a fifth (22.2%) to a third (34.5%) of the subjects had perceptual impairment in cognitive and role functioning. Financial difficulties, peripheral neuropathy and pain were most common symptoms reported as affected. A third of the survivors were worried that sex would be painful, and 36.6% indicated that their sexual activity as affected. The overall QoL scores for survivors who had surgery, chemoradiation and radiation-alone were 86.1 (SD 9.7), 76.9 (SD 17.7), and 80.7 (SD 14.7), respectively (p = 0.025). The predictors of survivor’s overall QoL were loss of appetite [Adjusted Odd Ratio (AOR) = 9.34, 95% Confidence Interval (CI) = 2.13–35.8, p = 0.001], pain (AOR = 3.53, 95% CI = 1.25–9.31, p = 0.017) and body image (AOR = 5.89, 95% CI = 1.80–19.27, p = 0.003).

Conclusion

About 75% of the survivors had a good overall quality of life. Primary surgical treatment affords the best prospects for quality of life with the least symptom complaints and financial burden. Loss of appetite, pain or diminution in body image perception predicted the overall quality of life of cervical cancer survivors after treatment.

Results of the Optimune trial: A randomized controlled trial evaluating a novel Internet intervention for breast cancer survivors

INTRODUCTION

After the acute treatment phase, breast cancer patients often experience low quality of life and impaired mental health, which could potentially be improved by offering cognitive behavioural therapy (CBT) and addressing exercise and dietary habits. However, CBT and other behavioural interventions are rarely available beyond the acute treatment phase. Internet-based interventions could bridge such treatment gaps, given their flexibility and scalability. In this randomized controlled trial (RCT), we investigated the effects of such an intervention ("Optimune") over three months.

METHODS

This RCT included 363 female breast cancer survivors (age range = 30-70), recruited from the community, who had completed the active treatment phase. Inclusion criteria were: breast cancer diagnosis less than 5 years ago and acute treatment completion at least 1 month ago. Participants were randomly assigned to (1) an intervention group (n = 181), in which they received care as usual (CAU) plus 12-month access to Optimune immediately after randomization, or (2) a control group (n = 182), in which they received CAU and Optimune after a delay of 3 months. Primary endpoints were quality of life (QoL), physical activity, and dietary habits at three months. We hypothesized that intervention group participants would report better QoL, more physical activity, and improved dietary habits after 3 months.

RESULTS

Intention-to-treat (ITT) analyses revealed significant effects on QoL (d = 0.27, 95% CI: 0.07-0.48) and dietary habits (d = 0.36, 95% CI: 0.15-0.56), but the effect on physical exercise was not significant (d = 0.30; 95% CI: 0.10-0.51).

DISCUSSION

These findings suggest the effectiveness of Optimune, a new CBT-based Internet intervention for breast cancer survivors, in facilitating improvements in quality of life and dietary habits. Efforts to disseminate this intervention more broadly may be warranted.

Experience of Adolescent Survivors of Childhood Cancer about Self-Care Needs: A Content Analysis

Objective:

In cancer care management, patients or their family are usually responsible for continuing health care. Achieving this goal requires identification of their self-care needs. The purpose of this study is to explore the perception of self-care needs of adolescent cancer survivors.

Methods:

This study was conducted by the qualitative content analysis method. Participants were 19 adolescent childhood cancer survivors and six parents, nurses, physicians, and charity institution staff from children teaching hospitals in Iran. Participants were selected through purposeful sampling, and individual semistructured interviews were used for data collection. Graneheim and Lundman stages of content analysis were employed for data analysis. Data were managed with the MAXQDA10 software.

Results:

Content analysis revealed nine subcategories as follows: (1) nutritional protection, (2) prevention from infection, (3) prevention from physical damage, (4) control over cancer recurrence, (5) informational needs, (6) pain management, (7) releasing positive thoughts, (8) continuing routine life, and (9) family protection. The first six subthemes were related to protection against physical distress, and the final three ones were related to protection against psychological distress. These two categories form one theme: “protective self-care need” as an essential self-care need in adolescent cancer survivors.

Conclusions:

Pediatric and school health nurses can prepare strategies to meet these needs by providing effective informational and psychosocial supports, and healthcare providers are able to check periodically the status of survivors care to provide second or third level of care to prevent escalation and incidence of the adverse outcomes of the disease.

Biological function and molecular mechanism of piRNA in cancer

Cancer is the second leading cause of death globally. piRNAs, which are a novel type of identified small noncoding RNA (ncRNA), play a crucial role in cancer genomics. In recent years, a relatively large number of studies have demonstrated that several piRNA are aberrantly expressed in various kinds of cancers including gastric cancer, bladder cancer, breast cancer, colorectal cancer and Lung cancer and may probably serve as a novel therapeutic target and biomarker for cancer treatment. The present review summarized current advances in our knowledge of the roles of piRNAs in cancer.
