[A Case of Stage Ⅳ Gastric Cancer Completely Resected after Successful Second-Line Chemotherapy]

A 60s man was diagnosed with advanced gastric cancer(cT4b[PAN], cN+, cM0, cStage ⅣA). He started first-line chemotherapy consisting of S-1 and cisplatin, but tumor markers remained elevated and CT showed cancer progression. He then started second-line chemotherapy consisting of ramucirumab and paclitaxel. The tumor markers decreased, and CT revealed tumor regression. A distal gastrectomy with D2 lymph node dissection was performed as conversion surgery. The patient had an uncomplicated postoperative course and was discharged early from the hospital. A histological analysis confirmed complete resection of the Grade 1a tumor. The RAM plus PTX regimen was restarted on postoperative day 57. At 15 months postoperative, the patient remained alive and relapse-free.
