About

The purpose of this study was to investigate the role of immunonutrion compared with standard nutrition in reducing oral mucositis in patients with locally advanced nasopharyngeal carcinoma.

Full description

Oral mucositis is the most common adverse reaction in patients with nasopharyngeal carcinoma receiving chemoradiotherapy, of which 40-50% of patients are severe (grade 3-4). Oral mucositis usually results in pain, dysphagia, reduced feeding, and malnutrition. Severe malnutrition in turn increases the risk of severe oral mucositis. Persistent severe oral mucositis will lead to delay and interruption of treatment, impairing patients'quality of life and prognosis. It's reported that nutritional intervention can not only reduce the risk and severity of oral mucositis and improve the nutritional status of patients with head and neck tumors, but also improve patients' tolerance to radiotherapy, quality of life, and prognosis.

Immunonutrition refers to the addition of high content of immune nutrients on the basis of sufficient calories, which not only ensures the supply of nutrition, but also takes into account the effects of anti-inflammation, regulating immunity, improving treatment tolerance, improving prognosis and so on. It has been reported that, comparing with standard enteral nutrition, the incidence of severe oral mucositis and esophagitis in patients with head and neck tumors treated with immunonutrition was lower, suffering less weight loss, and the antitumor immune response was enhanced. The 3-year OS and PFS were significantly improved in patients with good compliance.

It remains to be seen whether or not NPC patients receiving chemoradiotherapy can be benifit from immunonutritional therapy. Therefore, we conducted a prospective, multi-center, randomized controlled clinical study in patients with nasopharyngeal carcinoma who received radiotherapy and chemotherapy without metastases, to further improve the quality of life and prognosis of patients with nasopharyngeal carcinoma.

190 participants in 2 patient groups

Immunonutrition Group

Experimental group

Description:

Induction chemotherapy (IC) + Concurrent chemoradiotherapy (CCRT) and enteral immunonutrition Patients receive gemcitabine (1000 mg/m² d1,8) and cisplatin (80mg/m² d1) every 3 weeks for 2-3 cycles before radiotherapy and then receive intensity modulated-radiotherapy (IMRT), concurrently with cisplatin (100mg/m² d1) every 3 weeks for 2-3 cycles. Patients receive enteral immunonutrition, Oral Impact®, Nestle, 250ml/ bottle, 2 bottles per day, from 5 days before radiotherapy to the end of radiotherapy.

Treatment:

Dietary Supplement: Enteral immunonutrition

Control Group

Active Comparator group

Description:

Induction chemotherapy+Concurrent chemoradiotherapy and standard enteral nutrition Patients receive gemcitabine (1000 mg/m² d1,8) and cisplatin (80mg/m² d1) every 3 weeks for 2-3 cycles before radiotherapy and then receive intensity modulated-radiotherapy (IMRT), concurrently with cisplatin(100mg/m² d1) every 3 weeks for 2-3 cycles. Patients receive isocaloric standard enteral nutrition formula (ENSURE®), 250 mL per administration, 3 times per day, from 5 days before radiotherapy to the end of radiotherapy. Preparation of the 250 mL dose involves adding 200 mL of potable water to a cup and slowly stirring in 52.7 g of ENSURE powder (approximately 6 scoops).

Treatment:

Dietary Supplement: Standard enteral nutrition
