title: [A Study of Preoperative Chemotherapy with S-1 plus Cisplatin for Advanced Gastric Cancer].
abstract: We studied the effects of preoperative chemotherapy with S-1 plus cisplatin for advanced gastric cancer. There were 16 patients who underwent radical surgery with neoadjuvant chemotherapy between 2000 and 2015. The indications for this were advanced gastric cancer with bulky N2 or N3 lymph nodes, or stage above T4a. Seven patients (43%) showed adverse events, all of which were tumors above Grade 3. Response evaluation showed PR in 13 cases (81%). The histopathological evaluation was Grade 0 in 8 patients (50%) and Grade 1a or above in 8 (50%). Death from recurrence within a year occurred in 4 cases, and 7 patients survived with no recurrence for over 5 years. All cases of survivors with no recurrence had a histopathological evaluation of Grade 1 or above. Three cases (75%) with recurrence and death within a year all had with Grade 0 tumors. We concluded that neoadjuvant chemotherapy with S-1 plus cisplatin was effective for advanced gastric cancer and that histopathological evaluation was invaluable for accurate prognosis.
