Role of intensive nutrition support and prophylactic percutaneous endoscopic gastrostomy during concomitant chemoradiotherapy for oropharyngeal cancer

Predictors of the need for prophylactic percutaneous endoscopic gastrostomy in head and neck cancer patients treated with concurrent chemoradiotherapy

BACKGROUND

We investigated whether prophylactic percutaneous endoscopic gastrostomy (PEG) is used effectively for patients treated with definitive concurrent chemoradiotherapy (CCRT) and the predictors of the need for PEG.

METHODS

326 patients with laryngeal, oropharyngeal or hypopharyngeal cancers were retrospectively reviewed.

RESULTS

The PEG tube use group had more favorable results than the total parenteral nutrition and nasogastric tube groups in terms of rate of serum albumin loss, incidence of severe fever and aspiration pneumonia, CCRT completion rate and hospitalization period. However, it was inferior to oral intake. Analysis of the relative risk of requiring enteral or parenteral nutrition revealed that performance status (PS) 2, primary site (supraglottis, oropharynx, or hypopharynx), N3 disease, and cisplatin were predictors of the need for nutritional support.

CONCLUSIONS

Prophylactic PEG is effective for patients treated with definitive CCRT and is especially required for patients with PS2 or oropharyngeal cancer.

The Multidisciplinary Team (MDT) Approach and Quality of Care

The core function of a multidisciplinary team (MDT) is to bring together a group of healthcare professionals from different fields in order to determine patients' treatment plan. Most of head and neck cancer (HNC) units are currently led by MDTs that at least include ENT and maxillofacial surgeons, radiation and medical oncologists. HNC often compromise relevant structures of the upper aerodigestive tract involving functions such as speech, swallowing and breathing, among others. The impairment of these functions can significantly impact patients' quality of life and psychosocial status, and highlights the crucial role of specialized nurses, dietitians, psycho-oncologists, social workers, and onco-geriatricians, among others. Hence, these professionals should be integrated in HNC MDTs. In addition, involving translational research teams should also be considered, as it will help reducing the existing gap between basic research and the daily clinical practice. The aim of this comprehensive review is to assess the role of the different supportive disciplines integrated in an MDT and how they help providing a better care to HNC patients during diagnosis, treatment and follow up.

Percutaneous Endoscopic Gastrostomy Tube Placement in Patients with Head and Neck Cancer Treated with Radiotherapy

Background and aim

The primary aim of our study was to evaluate percutaneous endoscopic gastrostomy (PEG) tube placement depending on body weight and body mass index in patients undergoing radiotherapy (RT) for head and neck cancer (HNC). A secondary aim was to evaluate the course of weight change following PEG placement.

Methods

We retrospectively reviewed the medical records of 186 patients with HNC undergoing radiotherapy (RT) or chemoradiotherapy (CRT) at our institution between January 2010 and August 2017. Initial weight and nutritional intake were analyzed prior to RT initiation and then followed throughout treatment until completion. Based on these data, the indication of PEG placement was determined. Medical records were also reviewed to analyze PEG-related acute toxicities.

Results

A total of 186 patients met inclusion criteria. Patients were most commonly male (n=123, 66.1%) with squamous cell carcinoma (n=164, 88.2%). Patients who had dysphagia prior to treatment initiation as well as patients with a BMI <18.5 kg/m² needed PEG placement earlier during the treatment course. Low-grade toxicities related to PEG insertion were observed in 10.7% patients, with peristomal pain and redness adjacent to the PEG tube insertion site being most common. High-grade toxicities, such as peritonitis and organ injury, were found in 4.9% of patients.

Conclusion

Underweight patients and those with preexisting dysphagia should be closely screened during RT for weight loss and decreased oral intake. For weight loss greater than 4.5% during the treatment of HNC, early PEG-tube placement should be considered. Further prospective studies are needed to confirm these findings, and delineate a scoring system for timing of PEG use (prophylactic vs reactive) as well as assess the quality of life in patients with HNC who receive PEG placement.

What Factors Affect Changes in Body Composition and Swallowing Function in Patients Hospitalized for Oral Cancer Surgery?

PURPOSE

There are few studies about sarcopenia before and after surgery for oral cancer. Therefore, we examined body composition during hospitalization and factors affecting weight loss, skeletal muscle mass index (SMI) reduction, and swallowing function at discharge in this patient group.

PATIENTS AND METHODS

A prospective survey was conducted at Tokyo Medical and Dental University Dental Hospital for patients who underwent primary surgery for oral cancer and reconstruction using free flaps. We compared body weight, SMI, grip strength, and walking speed at admission and discharge. We also examined factors affecting weight loss and SMI reduction and the functional oral intake scale (FOIS) score at discharge.

RESULTS

There were 26 patients that we could survey during the period. As a result of Wilcoxon's signed-rank test, body weight, SMI, and grip strength were significantly reduced during hospitalization, but no reduction was noted for sarcopenia. As a result of multiple regression analysis, postoperative chemoradiotherapy was a risk factor for weight loss, reduced SMI, and low FOIS score at discharge.

CONCLUSION

Postoperative chemoradiotherapy is a risk factor for weight loss, muscle mass loss, and dysphagia at discharge, and chemoradiotherapy may affect rather than an invasion of surgery. After surgery, besides follow-ups for cancer, oral cancer patients should be followed up to assess dysphagia, undernutrition, and sarcopenia.
