Preoperative Dose-dense Chemotherapy With Weekly Cisplatin, Epirubicin and Paclitaxel to Treat Patients With Locally Gastric Cancer

If surgery remains the main treatment for gastric cancer without distant metastases; perioperative-chemotherapy increased the likelihood of progression free survival. Perioperative chemotherapy appears to have many advantages : to reduce the tumor volume, to improve the R0 resection rate, and to act on micro-metastases. Therefore, peri-operative chemotherapy combining cisplatin, epirubicin and 5-Fluorouracile is a validated strategy to treat gastric cancer. However, several pitfalls remained. Particularly, only 42% of patients could received post-chemotherapy, due to post-operative complications and toxicities. To overcome this limitation, the investigators will conduct a phase II clinical trial assessing the clinical interest of a dose-dense preoperative chemotherapy combining cisplatin (P), epirubicin (E) and paclitaxel (T). The increasing evidence of taxane's role in gastric cancer treatment, as well as the biological synergisms reported in paclitaxel/cisplatin and paclitaxel/epirubicin combinations, sustain the development of dose density based on PET combination in gastric carcinoma. The aim of the IPEC-GC study is to evaluate the effectiveness of this PET preoperative regimen
