To evaluate the efficacy and safety of SOX or mFOLFOX6 as neoadjuvant chemotherapy in patients with resectable rectal cancer, and to identify the more promising regimen.
1. Patient registration procedure
If it is confirmed that the subject meets the inclusion criteria and correspondent none of the exclusion criteria, the subject is registered by using CReS Kyushu registration/allocation system (CK-RAS). The registration with CK-RAS is available for 24hr (URL: https://reg.cres-kyushu.or.jp/qmin/login/) and needs for individual ID and password.
2. Quality management
A central monitoring or in-site monitoring are carried out based on the data from case report form (CRF) collecting at data coordinating center. In principle, an on-site monitoring is not carried out, but it may be carried out when the on-site monitoring is determined to need by Kyushu Study group of Clinical Cancer (KSCC) steering committee from the results of the central monitoring so on.
Data Monitoring Committee
A Data Monitoring Committee (DMC) has been established.
All data will be entered by the double entry method. Referential data rules, valid values, range checks, and consistency checks against data already stored in the database will be supported. Checks will be applied at the time of data entry into a specific field. Additional errors will be detected by programs designed to detect missing data or specific errors in the data. The investigator who receives the inquiry will respond by checking the original forms for inconsistency, checking other sources to determine the correction, modifying the original paper form entering a response to the query.
Regular monitoring report
A regular monitoring report generated by data coordinating center is submitted to KSCC Steering Committee, principal investigator, the DMC etc and it is reviewed according to "KSCC regulation on the monitoring". The information on the status of site EC approval and the achievement of enrollment: number of enrollment- total/per periodical, total/per site, is reported monthly using e-mail.

A site audit is carried out by the audit members of KSCC Coordinating Center, data coordinating center, medical staff of other site under the approval of the site director according to "KSCC regulation for site audit". The results of the audit are reported to the site director, KSCC Steering Committee, principal investigator etc. (if required, to DMC).
