The pathological complete response rate(pCR)
The lesion disappeared completely by pathology
Time frame: within 3 weeks after surgery
Overall survival (OS)
Baseline to measured date of death from any cause
Time frame: 3 years
Disease-free survival(DFS)
Baseline to measured date of recurrence or death from any cause
Time frame: 3 years
Disease Control Rate (DCR)
Percentage of participants who achieved a best overall response of CR or PR or Stable Disease (SD).
Time frame: 3 years
Percentage of Participants With Objective Response According to Modified Response Evaluation Criteria In Solid Tumors(mRECIST) v1.1
Objective response referred to participants with complete response (CR) or partial response (PR). CR: disappearance of all target lesions, non-target lesions, and normalization of tumor marker level. PR: greater than or equal to (\>=) 30% decrease in sum of the longest diameter (LD) of all target lesions taking as reference the screening sum LD. To be assigned a status of PR or CR, changes in tumor measurements had to be confirmed by repeat assessments that should have been performed no less than 4 weeks after the criteria for response were first met. Longer intervals as determined by the study protocol were also appropriate. Cumulative data (up to primary analysis cut-off date of 30-June-2015) are provided for both phase 2 and phase 3 within the results of this measure.
Time frame: within 3 weeks after surgery

45 Gray (unit) Gy/25f （1.8Gy/f/d，5 f/w）
The EORTC QLQ-C30 is a validated, cancer-specific 30-item patient-reported measure, and contains 14 domains to assess the impact of cancer treatment on 5 aspects of participants functioning (physical, role, cognitive, emotional, and social), 9 aspects of disease/treatment-related symptoms (fatigue, nausea and vomiting, pain, dyspnea, insomnia, loss of appetite, constipation, diarrhea) and a global QoL/overall health status scale. Questions used 4 point scale (1 'Not at all' to 4 'Very much'; with the exception of the QoL/health status scale which uses a 7-point scale (1 'very poor' to 7 'Excellent'). Each scale is transformed on a scale of 0-100; a higher score equals (=) a better level of functioning or greater degree of symptoms. Change of greater than or equal to (\>=) 10-points has been found to be clinically significant. Cumulative data (up to primary analysis cut-off date of 30-June-2015) are provided for both phase 2 and phase 3 within the results of this measure.
Time frame: Day 1 of each treatment cycle, at the study drug completion visit, and thereafter at follow-up
Adverse events
Toxicity according to the Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0.The number of Participants with adverse events will be recorded at each treatment visit.
Time frame: 3 years
