Brief Summary: Thymidylate Synthase TS is a key enzyme in the synthesis of DNA and the target enzyme inhibited by 5-fluorouracil 5-FU TS level in the tumour cells has been reported as predictive to response to 5-FU and a prognostic factor in colorectal and gastric cancer patients We plan to study TS by immunohistochemistry IHC in the paraffin blocks of tumour tissue

A combined comparative genomic hybridization CGH and expression microarray analysis of gastric cancer specimens before and after neoadjuvant chemotherapy CGH will be performed using standard technique routinely done in Dr Patrick Tans laboratory at the National Cancer Centre which determines the gain or loss of DNA copies of each chromosome Total RNA will be extracted from at least one biopsy sample which contains at least 50 cancer cells by homogenization of the tumour tissue and tri-sol method 5 ug of RNA were amplified and hybridized with the C-DNA microarrays of 18K targets

Primary Objective 1 Feasibility and safety of pre-operative chemotherapy in locally advanced gastric cancer

Secondary Objective

1 Complete clinical and pathological response rates to pre-operative chemotherapy in locally advanced gastric cancer
2 Complete resection rate
3 Time to recurrence disease free and overall survival
4 Correlation of clinical outcome with Runt-related transcription factor RUNX-3 methylation status and Thymidylate synthetase in the tumor tissue
5 Correlation of CGH and gene expression profile and their changes after chemotherapy with clinical outcome

Patients may be included in the study only if they meet all of the following criteria

Age at least 18 years Histologic or cytologic diagnosis of adenocarcinoma of stomach or gastric cardia Siewert Classification Type III Preoperative Stage T3-4NxM0 by endoscopic ultrasound CT of the abdomenpelvis and laparoscopy CT of the chest if it is a cardia lesion

Absence of malignant cells in peritoneal lavage fluid during laparoscopic examination

Patients must not have received any prior chemotherapy or hormonal therapy for the treatment of gastric cancer

Karnofsky performance status of 70 or higher Estimated life expectancy of at least 12 weeks

Adequate organ function including the following

- Bone marrow White blood cells WBC at least 35 x 109L Absolute neutrophil segmented and bands count ANC at least 15 x 109L Platelets at least 100 x 109L Haemoglobin at least 9gdL

- Hepatic Bilirubin within upper limit of normal ULN Aspartate transaminase ALT or Alanine transaminase AST not more than 25x ULN Alkaline phosphatase not more than 25x ULN

- Renal creatinine not more than 15x ULN Signed informed consent by patient or legal representative Patients with reproductive potential must use an approved contraceptive method if appropriate eg intrauterine device birth control pills or barrier device during and for three months after the study Females with childbearing potential must have a negative serum pregnancy test within 7 days prior to study enrollment

The study plans to recruit 30 patients in 12-18 months
