Trial Information

A Phase I Study of S-1 in Combination With Radiotherapy in Locally Advanced or Recurrent Gastric Cancer


This is a Phase I trial of S-1 given in treatment days with an oral dose from 30mg/m2/d to
80mg/m2/d, concurrently with radiation in patients with locally advanced or locally
recurrent gastric cancer. Patients will be treated with external beam radiation therapy in a
standard manner. S-1 will be administered for 6 dose levels,30/40/50/60/70/80mg/m2/d.
Patients will be assessed for acute toxicities according to CTCAE 3.0.


Inclusion Criteria:



- Histologically or cytologically proven locally advanced gastric adenocarcinoma in
patients undergoing R0, R1, R2 resection, or with unresectable or locoregional
recurrent disease

- Any prior chemotherapy is allowed in this protocol.

- No distant metastasis in liver,lung,,bone,CNS,no peritoneal transplantation

- No prior abdominal or pelvic radiotherapy.

- KPS ≥ 70,predictive life span no less than 6 months

- Patients must have normal organ and marrow function as defined below:

- Leukocytes greater than or equal to 3,000G/L

- Platelets: greater than or equal to 100,000/mcL

- Hemoglobin:greater than or equal to 10g/L

- Total bilirubin: within normal institutional limits

- AST/ALT: less than or equal to 1.5 times the upper limit

- Creatinine within normal upper limits

- Informed consent

- Without any serious complications,such as hypertension,coronary artery
disease,psychiatric history.

Exclusion Criteria:

- Patients with other cancer history except cervical carcinoma in situ and
non-malignant melanoma skin cancer

- With any distant metastasis in liver,lung,,bone,CNS,or peritoneal transplantation

- History of allergic reactions attributed to similar chemical or biologic complex to
S-1

- Uncontrolled illness including, but not limited to, active infection, symptomatic
heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness

- History of myocardial infarction within the past 6 months or history of ventricular
arrhythmia

- History of prior radiation to the abdomen

- Pregnant or lactating females
