Successful treatment of advanced gastric cancer by surgical resection following combination chemotherapy with oral S-1 and biweekly paclitaxel
Abstract
We report on the successful treatment of advanced gastric cancer by surgical resection following neoadjuvant chemotherapy. A 67-year-old man was referred to our hospital with a diagnosis of pancreatic cancer. Meticulous examination, however, revealed the presence of gastric cancer with ascites and large lymph node metastasis adjacent to the pancreas. We selected combination chemotherapy with oral S-1 and biweekly paclitaxel. After two courses, both the primary tumor and metastatic lymph nodes were greatly reduced, and the ascites had disappeared. Using laparoscopy, there was no evidence of peritoneal metastases, and the cytological examination was negative. The patient underwent distal gastrectomy with D2 lymph node dissection. Histological examination revealed that the cancer cells were still present in part, but no lymph node metastases were found. The tumor was pathologically diagnosed as pT2, pN0, P0, M0, CY0, and p-stage II. The patient is healthy over 4 years after surgery without recurrence.
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.
