A nutrition intervention in men with prostate cancer : Exploring effects on bowel symptoms from radiotherapy, patient experience, and nutrient intake

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Objective The main objective of this thesis was to explore the effects of a nutrition intervention on acute and late bowel symptoms in men with localised prostate cancer treated with pelvic radiotherapy (study I), participants’ experiences from receiving the nutrition intervention (study II), and associations with nutrient intakes (study III).Methods A total of 180 men with localised prostate cancer referred to curative radiotherapy targeting the prostate gland and pelvic lymph nodes were recruited to the trial. The participants were randomised to standard care plus a nutrition intervention aiming to modify fibre and lactose intakes (NIG; n=92) or standard care alone (SCG; n=88). Data on bowel symptoms and dietary intake were collected pre-treatment and at seven time points during a 26-month study period. Analyses of the effects of the nutrition intervention on bowel symptoms were conducted for the acute phase (up to 2 months post radiotherapy), and the late phase (7 to 24 months post radiotherapy). Semi-structured interviews were conducted with 15 participants from the NIG to explore experiences of the nutrition intervention.Results The nutrition intervention was associated with statistically significantly, but not clinically significantly, less bother from blood in stools and flatulence during the acute phase. The nutrition intervention was also associated with more bloated abdomen during the late phase (Study I). Social support, contributing to the greater good, prior knowledge, dietary information, and a small need for change facilitated adherence. While feeling limited, wanting to decide for themselves, the timing of the intervention, unmet expectations, and loss of motivation were described as barriers for adherence (Study II). A greater reduction of lactose was associated with decreased intake of calcium at the end of the radiotherapy period. A more modified fibre intake during the radiotherapy period was associated with increased vitamin C, but decreased selenium intake (Study III).Conclusions The effects from the nutrition intervention were small and inconclusive and do not support routine dietary advice aiming to modify fibre and lactose intakes as a mean to substantially reduce adverse effects from pelvic radiotherapy. Tailored nutritional interventions based on individual preferences, prior knowledge, and context, could enhance adherence. There were few associations between modified fibre and lactose intakes and nutrient intakes, thus, no recommendations can be made on whether such dietary advice should continue to be provided to men with prostate cancer undergoing pelvic radiotherapy.

Internet-based Psychosocial Support : Design, Effects and User Experience in the Cancer Setting
- 2020

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background and Aim Being diagnosed with cancer is often described as a major loss of control leading to severe psychological distress and symptoms of anxiety and depression can continue to affect the individual in the long term. The cancer and its treatment may influence all dimensions of health, thus the psychosocial support provided needs to be multifaceted and easy accessed. Internet-based interventions may be one way to provide such support, but evidence is limited. This thesis aimed to investigate the design, effects, and experiences of internet-based psychosocial support in cancer.Methods and Results Study 1 encompassed a co-creation development process resulting in the interactive support provided as the first step in an internet-based stepped care intervention (iCAN-DO). The effects of iCAN-DO were investigated in a randomised controlled trial, targeting individuals newly diagnosed with cancer and concurrent self-reported symptoms of anxiety and depression (according to the Hospital Anxiety and Depression Scale). Step 1 had a psycho-educative content involving self-care strategies and was available to the intervention group during the ten-month study period. Step 2 comprised a guided internet-based cognitive behavior therapy (iCBT) program and was offered those without improvement in anxiety and depression after using Step 1. The results showed that iCAN-DO improved symptoms of depression compared with standard care, while symptoms of anxiety were largely unaffected. Most participants used Step 1, while only a few used Step 2.In Study 2, aspects of usefulness, relevance, and usability in iCAN-DO were explored through qualitative interviews, analysed using content analysis. Results showed that standard healthcare did not meet the individuals' needs and iCAN-DO was used as complement, providing access to relevant, trustworthy information and support. Usability was affected by the perceived usefulness and ease of use of the intervention, as well as by the user´s circumstances in life and consequences of the cancer. The co-creation process in the development of Step 1 added relevance, but both steps 1 and 2 would have gained from being provided earlier, integrated into standard healthcare and more adaptable to the individual.Conclusion The thesis concluded that the internet-based intervention had positive effects on symptoms of depression in individuals newly diagnosed with cancer. Individuals with cancer experience several unmet needs in standard healthcare and since psycho-educative support including self-care advice seems feasible in this group, efforts are needed to incorporate internet-based support in regular oncology care. Since the intervention did not target all symptoms (i.e. anxiety) further research is needed on how to enhance efficacy and how to make iCBT more feasible for this group.
