Patients with advanced gastric cancer lose the surgical indications.Chemotherapy can improve the overall survival and quality of life,which is the main treatment option.But there is no standard chemotherapy regimen for the patients with advanced gastric cancer.Since its initial approval,S-1 is widely used in gastric cancer.Several studies were performed to explore combinations of S-1 with other cytotoxic drugs such as platinum,docetaxel,paclitaxel,and irinotecan.All these combinations were found to be promising,with response rates of around 40％-50％ and relatively favorable safety profiles.

OBJECTIVE To evaluate the clinic feature and therapeutic principles and to improve curative effect of mucoepidemoid carcinoma originated in nasal cavity and nasal sinuses. METHODS A restrospective review of clinic features ,therapeutic methods and consequences was undertaken in thirty cases with nasal cavity and nasal sinuse mucoepidemoid carcinoma and treated at the 81st hospital of CPLA from 1990 to 2001. RESULTS Twenty patients received surgery、radiotherapy and chemotherapy, of which sixteen survived in five to ten years follow-up . Six patients received surgery and radiotherapy, of which four survived in five years follow-up. Only one out of two patients who received radiotherapy and chemotherapy respectively survived in five years follow-up. The total five years survival rate was 73 %(22/30). CONCLUSION CT or MRI scan may be helpful to evaluate the location and scale of mucoepidemoid carcinoma.Final diagnosis rely on histopathology examination. Early radical resection combined with radiotherapy and chemotherapy pre- or postoperatively could improve five-year-survival rate and reduce recurrence rate.
