Study of Hypo-fractionated Neoadjuvant Radiotherapy for Locally Advanced Gastric Cancer

Summary

Gastric cancer is one of the most common malignant tumors in China, and the incidence and mortality rate are second in malignant tumors. The treatment of gastric cancer need integrated multidisciplinary treatment, and surgery is the only possible curative method for gastric cancer at present. Previous studies have reported that neoadjuvant chemoradiotherapy can downstage primary tumor to increase radical resection rate in order to improve the long-term prognosis of advanced gastric cancer. However, there is no study on the application of hypo-radiotherapy to neoadjuvant radiotherapy in gastric cancer. The aim of this study was to observe the maximum tolerated dose (MTD) and dose limited toxicity (DLT) of hypo-fractionated radiotherapy for locally advanced gastric cancer.
