Pancreatic cancer has a poor prognosis for its high malignancy. Radical surgical resection is an effective means for prolonging survival. However, only a few patients can be directly treated with surgical resection. Neoadjuvant therapy can reduce the tumor size, improve the relationship between the tumor and adjacent blood vessels，to gain surgical opportunities and prolonging patients' survival.
Nutritional treatment of cancer has been valued by more and more researchers. As an important branch of nutrition therapy, immunonutrition plays an important role in regulating the immune. Studies have shown that immunonutrition can reduce antitumor treatment related toxicity among patients with head and neck cancer, esophageal cancer. At present, most studies on immunonutrition therapy focus on perioperative patients, and there is no study on patients with pancreatic cancer undergoing radiotherapy.
This prospective, single-arm clinical trial aimed to explore the efficacy and safety of oral immunonutrition therapy in reducing acute toxicity after neoadjuvant chemoradiotherapy among pancreatic cancer patients. A total of 98 pancreatic cancer patients will be enrolled. All of the patients will receive oral immunonutrition therapy for 6 weeks from one week before radiotherapy. The total follow time is 4 months.
