Enteral Nutrition during Radiotherapy for Oropharyngeal Cancers: Prevalence and Prognostic Factors Based on HPV Status (A GETTEC Study)

Nutritional support during radiotherapy is crucial to tolerating and completing oropharyngeal squamous cell carcinoma (OPSCC) treatment. The impact of HPV status on nutritional support is debated. The objective was to evaluate the rate of Reactive Feeding Tube (RFT) use and determine its prognostic factors during definitive radiotherapy for OPSCC. All OPSCC patients treated from 2009 to 2014 were included in this multicentric retrospective study. The impact of tumor p16 status on the risk of RFT was assessed through multivariate analyses. Among the 543 patients, 103 patients required an RFT (19.0%). The use of RFT differed between centers (5% to 32.4%). In multivariate analysis, only tongue base involvement and concurrent chemotherapy were significantly associated with RFT (OR = 2.18 and 3.7, respectively). Tongue base involvement and concomitant chemotherapy were prognostic factors for RFT. HPV status was not a prognostic factor for enteral nutrition during radiotherapy for OPSCC.

Malnutrition in head and neck cancer patients: Impacts and indications of a prophylactic percutaneous endoscopic gastrostomy

INTRODUCTION

Head and neck cancer (HNC) patients often experience malnutrition before and during treatment. Prophylactic gastrostomy has emerged as an efficient tool for ensuring adequate nutrition. However, there is no suitable algorithm able to identify patients at high risk of malnutrition. The aim of this study was to describe the nutritional management, to assess the impact of prophylactic gastrostomy, and to identify predictors of malnutrition.

METHODS

This retrospective study included 152 patients treated with surgery, radiotherapy, or chemotherapy for HNC. The patients were classified according to their gastrostomy status (prophylactic or non-prophylactic). Nutritional, tumoral and treatment characteristics were reported. Clinical and nutritional outcomes were measured 6 weeks after the beginning of treatment. In order to describe the nutritional management and the impact of prophylactic gastrostomy on patients, univariate analysis was generated using chi-square test and Mann-Whitney test or Student's t-test. Logistic regression was performed to identify factors associated with malnutrition.

RESULTS

Forty-one patients received prophylactic gastrostomy whereas 111 patients had no nutritional support. Prophylactic gastrostomy placement was associated with a lower initial body mass index, with severe malnutrition, and with initial oral intake disorder. Patients who did not experienced prophylactic gastrostomy had much worse outcomes such as hospital readmissions (P=0.042), relative weight loss at 6 weeks (P<0.0001), dysphagia, severe malnutrition, and poor state of health (P=0.001). Our complication rates (4.9%) were lower than the usual range (5.9-9.3%) and no life-threatening complication was reported. Positive N status, oral intake disorder, concomitant radiochemotherapy, nasopharyngeal, and hypopharyngeal tumor site were significant predictive factors for malnutrition.

CONCLUSIONS

Prophylactic percutaneous endoscopic gastrostomy showed advantages in terms of hospital readmissions, relative weight loss at 6 weeks, dysphagia, severe malnutrition, and poor state of health. Tumoral, nutritional and treatment characteristics seem to be predictors for malnutrition. Hence, physicians should integrate these factors in their nutrition algorithm approach.

NUTRISCORE: A new nutritional screening tool for oncological outpatients

OBJECTIVES

The aim of this study was to design a new nutritional screening tool (NUTRISCORE) to detect nutritional risk in outpatients with cancer.

METHODS

A multicenter, cross-sectional study was conducted. We randomly selected outpatients receiving onco-specific, palliative, or symptomatic treatment for malignant neoplasms (including solid tumors and hematologic malignancies). These patients were assessed using the NUTRISCORE tool, the Malnutrition Screening Tool (MST), and the Patient-Generated Subjective Global Assessment (PG-SGA) to detect risk for malnutrition. The new tool included questions regarding the cancer site and active treatment. Sensitivity, specificity, and positive and negative predictive values were calculated for NUTRISCORE and MST using the PG-SGA as a reference method.

RESULTS

We evaluated 394 patients. According to NUTRISCORE, 22.6% were at risk for malnutrition. The MST detected a risk in 28.2%, and the PG-SGA found that 19% were malnourished or at nutritional risk. Using the PG-SGA as a reference method, the MST had a sensitivity of 84% and a specificity of 85.6%, whereas NUTRISCORE exceeded these values, at 97.3% sensitivity and 95.9% specificity. The better performance of NUTRISCORE as compared with MST was confirmed by the receiver operating characteristic curve analysis, with area under the curve values of 0.95 (95% confidence interval, 0.92-0.98) for NUTRISCORE and 0.84 (95% confidence interval, 0.79-0.89) for the MST.

CONCLUSIONS

NUTRISCORE has been found to be a novel, fast, and valid nutritional screening tool for outpatients with cancer. Its simplicity and high level of accuracy in detecting nutritional risk facilitates its applicability.

Malnutrition and Clinical Outcome of 234 Head and Neck Cancer Patients who Underwent Percutaneous Endoscopic Gastrostomy

Head and neck cancer (HNC) patients who underwent percutaneous endoscopic gastrostomy (PEG) present malnutrition risk and speech impairments. Their assessment relies on objective anthropometric/laboratory data. Focusing on HNC PEG patients, our aims were to evaluate: 1) outcome; 2) nutritional status when the patients underwent PEG; and 3) association of nutritional status/outcome, creating a survival predictive model. We evaluated the outcome based on NRS 2002, dietary assessment, body mass index (BMI), mid-upper arm circumference (MUAC), triceps skinfold thickness (TSF), mid-arm muscle circumference (MAMC), albumin, transferrin, and cholesterol on the day of gastrostomy. Using BMI, TSF, MAMC, and laboratory data, a survival predictive model was created. Of the 234 patients (cancer stages III-IV), 149 died, 33 were still PEG-fed, and 36 resumed oral intake (NRS-2002≥3, caloric needs <50% in all). BMI was 12.7-43. 189, 197, and 168 patients displayed, respectively, low MUAC, TSF, and MAMC. 91, 155, and 119 patients displayed low albumin, transferrin, and cholesterol. Albumin, cholesterol, and transferrin were strongly associated with the outcome. A predictive model was created, discriminating between short-term survivors (<4 months) and long-term survivors. HNC patients were malnourished. Using anthropometric/laboratory parameters, a predictive model provides discrimination between patients surviving PEG for <4 months and long-term survivors. Teams taking care of PEG patients may provide special support to potential short-term survivors.

[What nutritional management in patients with head and neck cancers undergoing radiotherapy? An overview]

Radiotherapy is an effective treatment for head and neck cancers but patients often experience side effects, which lead to malnutrition. Morbidity related to weight loss during treatment may include dehydration, hospitalization, compromised treatment efficacy, and reduced quality of life and may impact survival hence the importance of early nutritional management prior to radiotherapy. Multiple interventions have been implemented to help ameliorate the impact of treatment on weight loss and nutritional status, including the use of percutaneous endoscopic gastrostomy tubes. The goal of this overview is to search the predictive factors of malnutrition and an overview of the different types of nutritional interventions and their impact on the local control of the disease, mortality and quality of life of patients treated with radiotherapy or concomitant chemoradiotherapy.

[Nutritional management of patients with head and neck cancer treated with radiation]

Radiotherapy and chemotherapy are standard treatment of head and neck cancer alone or associated to surgical treatment. Early (during treatment or the following weeks) and late side effects contribute to malnutrition in this population at risk. In this context, nutritional support adapted by dietary monitoring and enteral nutrition (nasogastric tube or gastrostomy) are often necessary. The early identification of the patients with high malnutrition risk and requiring enteral nutrition is necessary to improve the tolerance and efficacy of treatment.
