Brief summary
Preoperative chemoradiotherapy(CRT) had been introduced in the comprehensive treatment of gastroesophageal junction and upper gastric cancers in the decade.According to some researches,CRT had shown its good curative effects in local control and prolonged overall survival.However,the optimization scheme for CRT and its influence to surgery remains controversial.Meanwhile,there were many design flaws in the past few research,such as the lack of adjuvant chemotherapy,the insufficiency in lymphnodes dissection.We decided to carry out the trial,eliminating all the bias as far as we can,to illustrate the efficacy and safety of CRT.
Interventions
The patients will receive radiotherapy in the total amount of 50Gy(25 fractions) preoperatively,concurrently combined with chemotherapy,which consist of oxaliplatin 40mg/m2 administrated on days 1,8,15,22,29 and S-1® 30mg/m2 twice per day on days 1 to 5 per week.
Within 5-6 weeks after the completion of neoadjuvant therapy,the patients in CCRT group will receive the radical total gastrectomy with D2 lymphadenectomy,and patients in the CT group will receive the surgery right after randomization.
Within 2 months after surgery,the patients will receive chemotherapy for 6 to 8 cycles ,consist of oxaliplatin 130mg/m2 administrated on day1 and S-1® 40-60mg twice per day on days 1 to 14 per 3 weeks.The S-1® dosage depends on the patient BSA(BSA\<1.25m2 40mg,1.25 m2≤BSA≤1.5 m2 50mg ,BSA\>1.5 m2 60mg). Patients in the CCRT group will receive 6 cycles of chemotherapy and patients in the CT group will receive 8 cycles of chemotherapy.
