Selective cyclooxygenase （COX）-2 inhibitors （coxibs） were developed as one of the anti-inflammatory drugs to avoid the various side effects of non-steroidal anti-inflammatory drugs （NSAIDs）. However, coxibs also have an ability to inhibit tumor development of various kinds the same way that NSAIDs do. Many experimental studies using cell lines and animal models demonstrated an ability to prevent tumor proliferation of COX-2 inhibitors. After performing a randomized study for polyp chemoprevention study in patients with familial adenomatous polyposis （FAP）, which showed that the treatment with celecoxib, one of the coxibs, significantly reduced the number of colorectal polyps in 2000, the U.S. Food and Drug Administration （FDA） immediately approved the clinical use of celecoxib for FAP patients. However, some coxibs were recently reported to increase the risk of serious cardiovascular events including heart attack and stroke. In this article we review a role of COX-2 in carcinogenesis of gastrointestinal tract, such as the esophagus, stomach and colorectum, and also analyze the prospect of coxibs for chemoprevention of gastrointestinal tract tumors.

Peritoneal metastasis of gastric cancer is mainly caused by the dispersion of free cancer cells from the serosal surface of the invaded stomach, from surgically transected lymphatic channels, and from tumor cell-containing blood from the primary lesion into the peritoneal cavity. Intraperitoneal chemotherapy (IPC) combined with surgery has performed for the prevention and treatment of peritoneal metastasis in gastric cancer. The efficacy of this technique is influenced by the pharmacokinetic advantage achievable with the anticancer drug, timing of administration, combination with hyperthermia, and tumor volume. The pharmacokinetic advantage for peritoneal cavity exposure relative to peripheral circulation by intraperitoneal delivery for drugs including cisplatin (10-fold advantage), mitomycin C (20- to 30-fold advantage), docetaxel (500-fold advantage), and paclitaxel (1000-fold advantage) has been confirmed. To avoid uneven drug distribution in the peritoneal cavity and the re-growth of residual tumor, it seems to be reasonable to perform IPC perioperatively;however, early perioperative intraperitoneal chemotherapy (EPIC) has a relatively high morbidity rate compared with intraoperative IPC. Hyperthermia has both cytotoxicity of itself and a synergistic effect with anticancer drugs, especially mitomycin C. In the adjuvant setting, patients with either hyperthermic intraperitoneal chemotherapy (HIPEC) or EPIC showed a significant improvement of survival compared to those with surgery alone. In addition, extensive intraoperative peritoneal lavage (EIPL) seems also to be a reasonable method to reduce free cancer cells in the peritoneal cavity. For the treatment of peritoneal metastasis, cytoreductive surgery which achieves R0 or R1 resection followed by IPC has demonstrated a survival benefit, whereas gross residual tumor (R2) treated by IPC has shown poor prognosis. Extensive cytoreductive surgery, such as peritonectomy, followed by IPC achieved long-term survival fo
