[A case of stage IV gastric cancer previously treated with TS-1 completely responding to second-line chemotherapy with weekly paclitaxel therapy].

We report herein a case with stage IV gastric cancer previously treated with TS-1 completely responding to second-line chemotherapy with weekly paclitaxel therapy. A 65-year-old female was diagnosed as having type 3 gastric cancer with para-aortic lymph node metastases. She underwent total gastrectomy with extended lymph node dissection on March 2003. Histopathological examination revealed that the tumor was poorly-differentiated adenocarcinoma with para-aortic lymph nodes metastases and completely resected. After the operation,she was treated by adjuvant chemotherapy with TS-1. In March of 2004, she suffered from hematuria, and a CT scan revealed para-aortic lymph nodes metastases and left kidney metastasis. Then, she was treated by a weekly infusion of paclitaxel as second-line chemotherapy. After 3 courses, the tumor disappeared and efficacy was judged as CR. Moreover, CR was maintained after 7 courses. At this writing in January of 2005, she is well and has been treated with paclitaxel without any severe adverse events. Therefore, weekly paclitaxel therapy was considered to be one of the promising second-line chemotherapies for advanced or recurrent gastric cancer previously treated by TS-1.
