Assessing the nutritional needs of men with prostate cancer

Nutrition services during prostate cancer androgen deprivation therapy

OBJECTIVE

Dietary interventions are effective strategies to mitigate multiple side effects from androgen deprivation therapy (ADT) in prostate cancer, however the perception of, and access to, nutrition services is relatively unknown.

METHODS

A qualitative study using semistructured, audio recorded interviews was conducted in men with prostate cancer treated with ADT for ≥3 months. Interviews explored (1) side effects of ADT and drivers for dietary change, (2) accessibility, barriers, facilitators and use of nutrition services and (3) the preferences for nutrition service delivery. Data were coded using interpretative descriptive techniques of textual interview data, and systematically summarised to generate thematical patterns, using NVivo software.

RESULTS

Interviews were completed of 20 men with prostate cancer treated with ADT (25.5±20.1 months). Thematic analysis revealed four overarching themes-(1) the changes from ADT: men revealed that weight gain, loss of muscle and strength from ADT were daily struggles that negatively impact body image and components of masculinity reduced; (2) strategies to take control: several dietary changes were trialled and restrictive in foods and nutrients. Barriers to accessing nutrition specialists were the cost for the service and absence of a clear referral pathway; (3) importance of nutrition knowledge: demand for specialised nutrition services with knowledge in addressing side effects from ADT; (4) diverse patients need diverse nutrition support: that includes peer or partner support, and technology supported nutrition content.

CONCLUSION

Evidence-based nutrition services are an unmet need for men treated with ADT. Future work is required to develop services that can be readily available and accessible to improve prostate cancer survivorship care.

Barriers and Facilitators to Supportive Care Implementation in Advanced Disease Prostate Cancer Survivors: A Theory-Informed Scoping Review

BACKGROUND

Individualized supportive care is recommended to manage the debilitating effects of advanced prostate cancer and its treatments. Yet, the implementation of supportive care in practice remains inconsistent.

OBJECTIVE

The aim of this study was to synthesize the barriers and facilitators to implementing supportive care interventions after identifying supportive care interventions for advanced prostate cancer survivors.

METHODS

PubMed, SCOPUS, CINAHL Complete, ProQuest, and PsycINFO were searched for relevant studies published between 2011 and 2020. Studies were included if they reported on a supportive care intervention and included a description of implementation barriers and/or facilitators. The Theoretical Domains Framework was used to characterize implementation barriers and facilitators.

RESULTS

Of the 620 articles identified, 13 met all prespecified inclusion criteria. Primary barriers were related to the domains of environmental context and resources (eg, limited resources), knowledge (eg, insufficient knowledge on efficacy of supportive care), and beliefs about capabilities (eg, lack of confidence in materials). Facilitators fell under environmental context and resources (partnerships with local services), reinforcement (eg, partners inclusion), and skills (eg, delivery by professionals).

CONCLUSIONS

This scoping review highlights barriers and facilitators that affect supportive care implementation. Future research that focuses on overcoming barriers and maximizing facilitators is needed to improve, modify, or supplement existing supportive care implementation practices.

IMPLICATIONS FOR PRACTICE

As the number of advanced prostate cancer survivors continues to increase, supportive care must become the standard of care. Future interventions must incorporate increased knowledge and funding, alternative delivery models, and consistent use of specialty nurses.

Patient and carer experiences of nutrition in cancer care: a mixed-methods study

PURPOSE

Evidence-based guidelines exist to guide health professionals and services about cancer nutrition care; however, the views of cancer patients and carers are not well understood. This study aimed to understand the experience and needs of cancer patients and carers regarding nutrition care across the care continuum.

METHODS

Using a mixed-methods approach, cancer patients and carers completed a cross-sectional online survey and focus groups. Participants were recruited through health services and cancer organisation consumer networks via email distribution lists, e-newsletters, and social media. Focus groups were audio-recorded, transcribed, and analysed using content analysis.

RESULTS

Of 165 survey respondents, only 51% (n=84) reported they talked to a health professional about their nutrition care at any time-point, and only 32% with a dietitian. The majority (84%) of patients and carers felt nutrition was important at one or more time-points in their cancer path, indicating during and after cancer treatment the most important. However, perceived support from health professionals for nutrition care was deemed low at all time-points. Five focus groups were held (n=20; 16 patients, 2 carers, 2 both patients/carers) and five themes emerged: nutrition information, experiences and need; control over diet and nutrition; importance and value of nutrition; access to support; what optimal nutrition care looks like.

CONCLUSION

Patients and carers felt nutrition was important during their cancer path, but perceived support from health professionals for nutrition care was low. This study has highlighted patient and carer nutrition experiences that will inform development of a co-designed optimal cancer nutrition care pathway.

Nutrition Education Seminars for Prostate Cancer-Diet and Prostate Program: Evaluation and Recommendations (DAPPER Study)

Nutrition is important for prostate cancer (PCa) care as it may influence PCa progression and risk of comorbid diseases. The aim of this pilot study was to assess changes in knowledge and satisfaction in men with PCa following attendance at a nutrition education seminar. Fifty-two men with PCa attended nutrition education seminars instructed by a Registered Dietitian. Participants completed the Revised General Nutrition Knowledge Questionnaire (GNKQ-R) preseminar and 2 weeks postseminar, along with a satisfaction survey. Increased nutrition knowledge was observed through a significant (P = 0.023) improvement in mean scores of 71.6% (P < 0.005) preseminar compared with 79.3% (P < 0.005) postseminar on the GNKQ-R. Participants reported the seminar as a satisfactory method for meeting their diet information needs. Using thematic analysis 3 themes emerged: importance of diet information, desire for an integrative approach, and the value of group learning. This pilot study found that a group nutrition education seminar may be an effective and satisfactory approach to fulfilling the dietary information needs of this population. Group education may be an economically sustainable approach with potential application in other tumour sites or health conditions.

Nutritional Status and Health-Related Quality of Life in Men with Advanced Castrate-Resistant Prostate Cancer

BACKGROUND

Despite professional recommendations malnutrition is not adequately addressed in cancer patients. Here, we explored whether nutritional status (NS) is associated with HRQoL in men with metastatic castrate-resistant prostate cancer (mCRPC). Methods: Men with mCRPC enrolled into this prospective observational study were allocated to one of the four NS categories based on clinical, laboratory, and patient self-reported criteria: well-nourished (WN), nutritional risk without criteria for cachexia/sarcopenia (NR), sarcopenia, and cachexia. The HRQoL was evaluated by the Functional Assessment of Cancer Therapy-Prostate (FACT-P) questionnaire. Association between NS and self-reported HRQoL was sought by the linear regression model, which was adjusted for known prognostic variables and body mass index. Results: Over the period of two years, 141 patients were enrolled. Their median age was 74.1 years (IQR 68.6-79.4 years) and majority of them were minimally symptomatic. Fifty-nine patients (41.8%) were WN, followed by 24 (17%), 42 (29.8%), and 16 (11.4%) patients with NR, sarcopenia, and cachexia, respectively. As compared to WN patients, all three other NS categories were significant negative predictors of HRQoL (P < 0.04). Conclusions: Abnormal NS is highly prevalent in men with mCRPC and is negatively associated with their HRQoL, which supports the recommendation for management of malnutrition in these patients.

Prostate Cancer Prehabilitation and the Importance of Multimodal Interventions for Person-centred Care and Recovery

BACKGROUND

Prostate cancer is the second most commonly diagnosed cancer globally. Cancer prehabilitation is defined as a process on the continuum of care that occurs between the time of a cancer diagnosis and the beginning of acute treatment. This article will discuss the importance of prostate cancer prehabilitation interventions in optimising physical and psychological recovery to enhance person-centred care.

DATA SOURCES

Electronic databases including CINAHL, MEDLINE, PsychINFO, Scopus, professional websites, and grey literature were searched using Google Scholar.

CONCLUSION

Prehabilitation in cancer care aims to enhance perioperative care and recovery. An emerging field of research suggests that the preoperative period may be physically and psychologically salient to introduce modifiable self-management behaviours to optimise overall recovery.

IMPLICATIONS FOR NURSING PRACTICE

Prostate cancer specialist nurses provide the hub of person-centred care across the entire cancer care continuum embedded within the multidisciplinary team. Individually tailored interventions such as exercise and pelvic floor muscle training programmes, nutritional advice, anxiety and depression reduction, and sexual well-being interventions should be considered in the prehabilitation phase of the cancer care continuum.
