Abstract

Objectives: Individuals who have survived cancer may benefit from dietary modifications to improve quality of life and future health outcomes. The aim of this study was to explore dietary habits and experiences of nutritional support in patients with a cancer diagnosis who have received radiotherapy to the pelvic area.

Methods: A mixed-methods approach was used. Individuals diagnosed with a pelvic cancer (anal, bladder, rectal, and cancers of the reproductive organs), either undergoing or having completed pelvic radiotherapy 6 to 24 mo previously, were invited to participate in a postal survey. A purposive subsample was also invited to take part in telephone interviews. Thematic analysis of interview data was undertaken and integrated with data from quantitative analysis.

Results: The survey was completed by 254 (38%) respondents. Two-thirds of respondents (170) reported dietary changes since diagnosis; most notable changes were reduction of sugary foods (48%) and alcohol (41%). Receipt of support from the health care team was significantly associated with dietary change (odds ratio, 3.26; 95% confidence interval, 1.58-6.75); however, only 43% (108) had received dietary support from the health care team. Of the respondents, 68% (171) said they would like to receive additional dietary support. The effect of the condition on diet was highlighted in the theme "Impact of diagnosis and treatments on dietary choices." Self-management of disease was influenced by personal resources, social resources, comorbidities and disabilities, influence of work, regaining normality, and barriers to dietary changes.

Conclusion: Lack of routine provision of nutritional care to patients after a cancer diagnosis and patient interest in this area highlighted unmet needs in managing diet-related problems and leading a healthy future lifestyle.
