Nutritional counseling was not enough to maintain dietary intake and nutritional status in head and neck cancer patients undergoing radiotherapy: a historical control study for future intervention in China

Prevention of weight loss in patients with head and neck cancer in ongoing radiation or chemoradiation therapy-A systematic review and meta-analysis

PURPOSE

This systematic review (PROSPERO: CRD4202345740) identified and synthesised existing evidence on nutrition interventions performed by healthcare professionals, and the contents of the interventions that prevented weight loss in patients with HNC undergoing RT/CRT.

METHODS

We included quantitative studies. PubMed, CINAHL, Cochrane Library, and Scopus were searched, and the outcomes of interest were weight change and nutritional status. A narrative synthesis was undertaken to elaborate on the findings across the included studies. Furthermore, a meta-analysis was conducted.

RESULTS

A total of 27 studies were identified. Most focused on the effect of oral nutritional supplements (ONS) and individualised nutrition counselling (INC). A beneficial effect of ONS combined with weekly INC were identified, and compliance, management of adverse effects, involvement of family as well as the knowledge and approach of the healthcare professionals were identified as key elements when supporting the management of nutrition intake in HNC patients during RT/CRT. The meta-analysis showed a non-significant effect of ONS, yet significant when combined with INC, and no overall effect of INC, but significant effect in the RCTs.

CONCLUSION

Our results suggest an optimal effect of ONS combined with weekly INC, requiring a focus on enhancing compliance as well as support from a multidisciplinary team to manage adverse treatment effects. Compliance must be emphasised to provide maximum support to the patient, as well as focus on the knowledge of the health care professionals performing the intervention. Further research on strategies to enhance patient compliance and involvement is needed.

Predict nutrition-related adverse outcomes in head and neck cancer patients undergoing radiotherapy: A systematic review

BACKGROUND

Acute nutrition-related adverse outcomes are common in head and neck cancer patients undergoing radiotherapy. Predictive models can assist in identifying high-risk patients to enable targeted intervention. We aimed to systematically evaluate predictive models for predicting severe acute nutritional symptoms, insufficient intake, tube feeding, sarcopenia, and weight loss.

METHODS

We searched PubMed, Web of Science, EBSCO, Embase, WanFang, CNKI, and SinoMed. We selected studies developing predictive models for the aforementioned outcomes. Data were extracted using a predefined checklist. Risk of bias and applicability assessment were assessed using the Prediction model Risk of Bias Assessment Tool. A narrative synthesis was conducted to summarize the model characteristics, risk of bias, and performance.

RESULTS

A total of 2941 studies were retrieved and 19 were included. Study outcome measure were different symptoms (n = 11), weight loss (n = 5), tube feeding (n = 3), and symptom or tube feeding (n = 1). Predictive factors mainly encompassed sociodemographic data, disease-related data, and treatment-related data. Seventeen studies reported area under the curve or C-index values ranging from 0.610 to 0.96, indicating moderate to good predictive performance. However, candidate predictors were incomplete, outcome measures were diverse, and the risk of bias was high. Most of them used traditional model development methods, and only two used machine learning.

CONCLUSIONS

Most current models showed moderate to good predictive performance. However, predictors are incomplete, outcome are inconsistent, and the risk of bias is high. Clinicians could carefully select the models with better model performance from the available models according to their actual conditions. Future research should include comprehensive and modifiable indicators and prioritize well-designed and reported studies for model development.

Effects of early nutritional intervention on oral mucositis and basic conditions in patients receiving radiotherapy for head and neck cancer: Randomized controlled trial (ChiCTR2000031418)

BACKGROUND & AIMS

This study aims to observe the effects of early nutritional intervention on radiation-induced oral mucositis (OM) and the nutritional status of patients with head and neck cancer (HNC) receiving radiotherapy.

METHODS

Eligible patients receiving radiotherapy for HNC were randomly divided into an early nutritional intervention group (enteral nutritional intervention was administered at the beginning of radiotherapy) and a late nutritional intervention group (enteral nutritional intervention was administered at the beginning of eating restriction) in a 1:1 ratio. The primary endpoint was radiation-induced OM. Secondary endpoints included nutrition-related indicators, immune function, overall survival (OS), progression-free survival (PFS), quality of life, and other radiotherapy-induced adverse effects.

RESULTS

A total of 100 patients were enrolled between 2020 and 2021, including 50 each in the early nutritional intervention group and in the late group. The incidence of Grade-III/IV OM was lower in the early treatment group than in the late treatment group (2% vs 14%, P = 0.059). By week 7 weight loss was significantly lower in the early group than in the late group (1.08 kg, 95% CI: 0.08-2.09, P = 0.035). Regarding the PG-SGA scores after receiving radiotherapy, the early group comprised more well-nourished and fewer malnourished patients than those in the late group (P = 0.002). The scores of the immune function indices of T cell CD3+, CD4+/CD8+, and B cell CD19+ were slightly higher in the early group than in the late group; however, the difference was not statistically significant (all P > 0.05). PFS and OS were better in the early group than in the late group; however, the differences were not statistically significant (P > 0.05).

CONCLUSIONS

Early nutritional intervention can effectively improve the nutritional status and reduce the incidence of high-grade OM in patients with HNC receiving radiotherapy.

Investigating sarcopenia, physical activity, and inflammation biomarkers in newly diagnosed oral cancer patients during curative treatment: A prospective longitudinal study

Objective

This prospective longitudinal study aimed to investigate changes in sarcopenia, physical activity, and inflammation biomarkers in patients with oral cavity cancer during curative treatment and explore their association with treatment outcomes.

Methods

Patients newly diagnosed with oral cavity cancer who underwent primary surgery with (chemo)radiation therapy were included. Along with physical activity and inflammatory markers, sarcopenia was assessed using a 5-time chair stand test, hand grip strength, and skeletal muscle index (SMI). Data were collected before operation and after 3 months (T₂) and 6 months after operation. Logistic regression and Cox proportional hazards models were used to identify predictors of treatment outcomes.

Results

Out of 56 patients, 21 (37.5%) had sarcopenia. SMI score, physical activity, and neutrophil-to-lymphocyte ratio (NLR) showed significant changes after surgery, with exacerbation at T₂. Patients with sarcopenia exhibited a significant decrease in SMI scores at T₂. Advanced cancer stage and sarcopenia were associated with treatment-related dysphagia (odds ratio [OR] ​= ​3.01, P ​= ​0.034; OR ​= ​7.62, P ​= ​0.018). Sarcopenia (OR ​= ​3.02, P ​= ​0.002) and NLR (OR ​= ​5.38, P ​< ​0.001) were significantly associated with infections. Pretreatment SMI independently predicted poor survival outcomes (hazard ratio ​= ​7.00, P ​= ​0.005).

Conclusions

Identifying patients with oral cavity cancer, sarcopenia, and high NLR levels can ensure prompt education and vigilant monitoring, potentially improving treatment outcomes and patient well-being during curative treatment.

High protein diet in digestive cancers

PURPOSE OF REVIEW

Recent advances in the nutritional management of patients with digestive cancers suggest that modulation of protein intake may significantly contribute to achieve nutritional and clinical benefits. By reviewing the available evidence, a quantitatively and qualitatively optimal protein intake could be derived.

RECENT FINDINGS

High protein diets (i.e., 1-1.5 g/kg body weight/day) appear key to maintain the adequate nutritional status, and may also contribute to achieve clinical benefits. This target appears particularly relevant in patients with digestive cancers at risk or already malnourished, or in older patients. During active cancer treatments, protein intake should be closer to the upper limit of the recommended intake. Also, high protein intake should be maintained beyond the periods of catabolic crisis associated with active treatments. In contrast with general reasoning, animal proteins should represent the majority of the recommended intake. Based on the available evidence, the intake of no specific amino acid can be strongly recommended to enhance anabolic potentials or the immune modulating effects of high protein diets.

SUMMARY

High protein intake, mostly based on animal proteins, should be recommended to patients with digestive cancers. However, this target should be translated into clinical prescription after considering the clinical and metabolic needs of the patients. The quest for the optimal protein intake of patients with cancer at different time points of their clinical journey is still open.
