A case of advanced gastric cancer responding to S-1/CDDP neoadjuvant chemotherapy, leading to a pathological complete response
Abstract
A 66-year-old man with cStage III B (cT4aN2H0P0M0) advanced gastric cancer in the cardia with esophageal invasion was treated with S-1/CDDP as neoadjuvant chemotherapy. After 3 courses of chemotherapy, a significant reduction in tumor burden was observed. Total gastrectomy and splenectomy with lymph node dissection (D2) were performed. Pathological specimens showed no cancer cells in the stomach and lymph nodes, indicating a pathological complete response.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
