Abstract
Objective:To analyze retrospectively the different efficacy between linear accelerator X-ray with three-dimensional conformal radiotherapy(3D-CRT) and dose boosted with gamma ray stereotactic body radiotherapy(SBRT) for locally advanced pancreatic cancer patients. Methods:A total of 61 patients with locally advanced pancreatic cancer were enrolled. All the patients were first performed by 3D-CRT, the volumes of irradiation included the pancreatic tumor (GTV) and the draining lymph node region, total scheduled dose was 40Gy in 20 fractions. Then boosted the dose to GTV, 21 cases with 3D-CRT(3D-CRT group), total dose of 46Gy;40 cases with SBRT(SBRT group), total dose of 56Gy. Results:The median survival time was 11.3 months for all cases. Patients with pretreatment KPS≥90, combined with chemotherapy and femal had better prognosis. The corresponding MSTs were 14.1 months vs 9.2 months(x2=8.992, P=0.003),13.0 months vs 9.6 months(x2=4.056, P=0.044) and 12.5 months vs 10.7 months(x2=3.953, P=0.047) respectively. The median survival time of 3D-CRT group and SBRT group were 7.5 months and 13 months, P<0.05. There were no statistic differences between 2 groups in terms of side effects induced by treatments. Conclusion:The gamma ray stereotactic body radiotherapy is effective and safe and has the trend to improve the survival rate for patients with locally advanced pancreatic cancer. Patients with better performance status before treatment, combined with chemotherapy and female may have better prognosis.关键词
