Health service nutrition practices and associations with clinical outcomes in patients undergoing resection for upper gastrointestinal cancer: results from the multi-centre NOURISH point prevalence study

Effect of Communication Mode on Disclosure of Nutrition Impact Symptoms During Nutrition Intervention Delivered to People With Upper Gastrointestinal Cancer

Individuals diagnosed with upper gastrointestinal cancers experience a myriad of nutrition impact symptoms (NIS) compromise a person's ability to adequately meet their nutritional requirements leading to malnutrition, reduced quality of life and poorer survival. Electronic health (eHealth) is a potential strategy for improving the delivery of nutrition interventions by improving early and sustained access to dietitians to address both NIS and malnutrition. This study aimed to explore whether the mode of delivery affected participant disclosure of NIS during a nutrition intervention. Participants in the intervention groups received a nutrition intervention for 18 weeks from a dietitian via telephone or mobile application (app) using behaviour change techniques to assist in goal achievement. Poisson regression determined the proportion of individuals who reported NIS compared between groups. Univariate and multiple regression analyses of demographic variables explored the relationship between demographics and reporting of NIS. The incidence of reporting of NIS was more than 1.8 times higher in the telephone group (n = 38) compared to the mobile group (n = 36). Telephone predicted a higher likelihood of disclosure of self-reported symptoms of fatigue, nausea, and anorexia throughout the intervention period. A trusting therapeutic relationship built on human connection is fundamental and may not be achieved with current models of mobile health technologies.

The impact of the prognostic nutritional index (PNI) in gastric cancer

BACKGROUND

Regarding the assessment of patients' immune and nutritional status, prognostic nutritional index (PNI) has been reported as a predictive marker for surgical outcomes in various types of cancer. The aim of our study was to evaluate the effect of PNI in prognosis of gastric cancer patients submitted to curative-intent resectional surgery.

MATERIAL AND METHODS

A retrospective analysis with 637 gastric cancer cases submitted to curative-intent surgery, between 2010 and 2017, in an upper GI surgery unit. We analyzed 396 patients that met the inclusion criteria for this study. The median follow-up was 37 (0-113) months.

RESULTS

According to Youden's method, the optimal PNI cutoff for OS was 41.625 (sensitivity 89.3% and specificity 41.3%). OS was significantly shorter in the lower-PNI group of patients when compared to the higher-PNI group (40.26 vs 77.49 months; p < 0.001). Higher PNI had a positive impact on OS in univariable analysis. When adjusted to pStage, higher PNI was still significantly associated with better OS (HR 0.405; CI 95% 0.253-0.649; p < 0.001). Regarding DFS, higher PNI was associated with better DFS (HR 0.421; CI 95% 0.218-0.815; p = 0.010). Higher-PNI group had a protective effect regarding postoperative morbidity and mortality.

CONCLUSIONS

In this cohort, PNI was disclosed to significantly impact GC patients' OS and DFS, including in multivariable analysis when adjusting for classical prognostic features. PNI can be used to predict patients at increased risk of postoperative morbidity and mortality. This index may be of use in identifying candidate patients who would benefit from perioperative nutritional support to improve surgical outcomes.
