  Purpose

The purpose of this study is to assess the safety and efficacy of S-1 and oxaliplatin combined with radiation by Phase I/II study.

The purpose of this study is as follows,

  • In phase I, to determine the dose limiting toxicities (DLTs) and the maximum tolerated dose (MTD).
  • In phase II, to evaluate the antitumor effect (pCR rate) and the safety .

Primary Outcome Measures:
  • Phase I: Determine the Recommended dose (RD) [ Time Frame: 10 weeks ] [ Designated as safety issue: Yes ]
    Based on the incidence of dose-limited toxicities(DLT), the RD is determined from 4 test levels

  • Phase II: pathological complete response rate [ Time Frame: 12-16 week ] [ Designated as safety issue: No ]
    Pathological complete response(pCR) rate is calculated by numbers of pCR cases (grade 3) devided the number of subjected cases.


Secondary Outcome Measures:
  • R0 resection rate [ Time Frame: 12-16 weeks ] [ Designated as safety issue: No ]
  • down staging rate [ Time Frame: 12-16 weeks ] [ Designated as safety issue: No ]
  • local reccurence rate [ Time Frame: 3 years ] [ Designated as safety issue: No ]
  • desease free survuval [ Time Frame: 3 years ] [ Designated as safety issue: No ]
  • safety [ Time Frame: 16-20 weeks ] [ Designated as safety issue: Yes ]
