Optimizing antiemetic therapy for children undergoing chemotherapy

Clinician perspectives on nutritional impairment in children undergoing cancer chemotherapy in Thailand: A qualitative descriptive study

Objective

This study aimed to explore the perspectives of pediatric oncology clinicians in Thailand on children's gastrointestinal ​symptoms, eating habits, and nutrition during cancer chemotherapy. Additionally, it sought to identify factors influencing children's nutritional status, including the characteristics of the children, clinician-related factors, and hospital-level factors.

Methods

The study involved pediatric oncology clinicians working at a tertiary hospital in Bangkok. Data were collected through interviews, focusing on three key areas: (1) children's gastrointestinal symptoms, eating behaviors, and nutrition, (2) clinicians' cognitions and behaviors that impact children's nutrition, and (3) environmental factors. Each participating clinician also identified a colleague who could offer additional perspectives. Interviews were conducted in the Thai language and analyzed using directed content analysis.

Results

A total of 22 participants were enrolled in the study, comprising sixteen nurses, four physicians, one child life specialist, and one Hospital Nutrition Service staff member. The majority of participants were female (95.4%), with an average age of 37.77 years and an average of 15.55 years of experience in caring for children with cancer. Factors influencing children's nutritional status included the children's cancer diagnosis, treatment exposures, and symptoms. Clinicians attributed changes in children's weight and eating patterns to these symptoms. Influential clinician-related factors included current practices that impacted children's symptoms and food intake. Hospital-level factors included both direct influences on children and those arising from clinical practices.

Conclusions

To optimize the nutritional status of Thai children undergoing chemotherapy, multi-level interventions are needed. These interventions should target children's symptoms, clinician knowledge, role norms, and address issues related to the hospital environment, specifically those elements that contribute to unpleasant experiences.

Effects of food-based interventions in the management of chemoradiotherapy-induced nausea and vomiting: a systematic review

BACKGROUND

Cancer treatment-related nausea and vomiting continue to be common and distressing symptoms for patients, despite improvements in antiemetics. Dietary modifications could potentially improve this symptom experience. Clinicians frequently provide dietary advice to patients, although the evidence base of such suggestions or recommendations is not clear.

PURPOSE

This systematic review aimed to examine the current literature on food interventions associated with improvements in cancer treatment-related nausea and vomiting.

METHODS

Eight electronic databases were searched with a specific search term strategy covering trials without time or language limitations. Eligible studies focused on a food substance, defined as any nutritious substance that people eat or drink to maintain life and well-being. Trials in children and adults during chemotherapy or radiotherapy were included. Cochrane risk of bias tool was used to assess trial quality and GRADE was used to assess the certainty in the effect of each outcome.

RESULTS

Seventeen trials were included, 3 focusing on children and 14 on adults. Two trials included patients receiving radiation. Ten out of 17 trials (59%) had a high risk of bias. Strongest evidence with highest certainty was found for dietary counseling to meet macronutrient requirements in reducing incidence of radiotherapy-related nausea and vomiting in adults (n=2 studies; n=124 participants; GRADE level: moderate). There was also moderate certainty in the beneficial effect of protein supplementation on nausea and vomiting incidence in adults during radiotherapy (n=2 studies; n=124 participants; GRADE level: moderate). A significant positive effect on CINV incidence and/or severity in adults was also found for dietary counseling to meet macronutrient requirements during chemotherapy, a peppermint drink, scaly wood mushroom, chamomile, protein with ginger, and a colorless odorless diet (GRADE level: low to very low).

CONCLUSIONS

The review identified food-based approaches that could improve the nausea and vomiting experience in patients with cancer and provide guidance to clinicians. However, confidence in these findings was low and studies were heterogeneous and mostly of low quality, requiring further investigation before stronger recommendations can be made. Future research is needed to confirm efficacy and safety.
