Abstract:
We report a case of conversion surgery after nivolumab treatment and chemotherapy for metastatic gastric cancer. A 75‒year‒old man was diagnosed as advanced gastric cancer with peritoneal dissemination. The patient was judged as unresectable gastric cancer and received SOX+nivolumab treatment. After 8 courses of chemotherapy, the primary lesion and enlarged lymph nodes were reduced and abdominal small nodules were disappeared. Consequently, we performed staging laparoscopy followed by laparoscopic distal gastrectomy with D2 lymph node dissection as a conversion surgery. Histopathological diagnosis was ypT2N0M0CY0, and ypStage ⅠB. The patient has been recurrence‒free for 6 months.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
