Abstract:
Objective To evaluate the clinical efficacy and adverse reactions of S-1 chemotherapy plus high-low oxygen radiotherapy synchronously in treatment of patients with locally advanced pancreatic cancer. Methods Sixty-four patients with locally advanced pancreatic cancer in Rizhao People's Hospital and the Affiliated Hospital of Qingdao University from January 2013 to October 2015 were randomly divided into study group and control group by using envelope method, in which the study group was treated with oral administration of S-1 plus high-low oxygen radiation synchronously and the control group with intravenous gemcitabine chemotherapy. The efficiency, disease control rate, clinical benefit rate, distant metastasis rate, survival rate and adverse reactions of the two groups were compared. Results The effective rates of the study group and the control group were 70.4 %(19/27)and 32.1 %(9/28),the difference was statistically significant (χ2=8.04,P<0.01), and the disease control rates were 88.9 % (24/27) and 67.9 % (19/28) (χ2= 3.56, P >0.05). The clinical benefit rates of the study group and the control group were 77.8 % (21/27) and 57.1 % (16/28) (χ2=2.66,P >0.05), and the distant metastasis rates were 63.0 %(17/27) and 71.4 %(20/28) (χ2=0.45, P > 0.05). The 1-year survival rates of the study group and the control group were 63.0 % (17/27) and 32.1 % (9/28), and the 2-year survival rates were 37.0 % (10/27) and 10.7 % (3/28), the differences were statistically significant (χ2= 5.24, P < 0.05; χ2= 5.28, P< 0.05). While there were no significant difference in the incidence of serious adverse reactions between the two groups (P> 0.05). Conclusion The treatment of locally advanced pancreatic cancer with S-1 plus high-low oxygen radiotherapy synchronously is better than that with intravenous gemcitabine chemotherapy in terms of effective rate, 1-year survival rate and 2-year survival rate,with no increase of adverse reactions.
