Preoperative S-1/OHP With Radiation Therapy for Low-lying Rectal Carcinoma in Neo-adjuvant Setting
A Phase I/II Study of S-1 and Oxaliplatin Combined With Radiation for Preoperative Locally Advanced Rectal Carcinoma. (SHOGUN Trial)
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 .

Measure Description |
Time Frame |
|---|---|---|
|
Phase I: Determine the Recommended dose (RD)
Time Frame: 10 weeks
|
Based on the incidence of dose-limited toxicities(DLT), the RD is determined from 4 test levels
|
10 weeks
|
|
Phase II: pathological complete response rate
Time Frame: 12-16 week
|
Pathological complete response(pCR) rate is calculated by numbers of pCR cases (grade 3) devided the number of subjected cases.

12-16 week
