Third-line chemotherapy with paclitaxel, irinotecan hydrochloride and cisplatin for recurrent gastric cancer: a case report.

With the availability of new chemotherapeutic agents such as S-1 and paclitaxel (TXL) for advanced gastric cancer, the development of a strategy for a third-line chemotherapy is urgently needed. We treated a patient with recurrent gastric cancer using TXL, irinotecan hydrochloride (CPT-11) and cisplatin (CDDP) as a third-line chemotherapy. The patient was a 46-year-old man who had undergone total gastrectomy for advanced gastric cancer with lymph node metastases. For postoperative recurrence, he was first treated with S-1 as an outpatient; however, tumor markers increased, and para-aortic lymph node metastasis was revealed by thoracic and abdominal CT scan. A second-line therapy with weekly TXL and CDDP was then added, but resulted in PD. Therefore, combination chemotherapy with TXL, CPT-11 and CDDP was started biweekly as a third-line chemotherapy. TXL (80mg/m2) was infused over 1 hour after short premedication, followed by CPT-11 (25mg/m2) and CDDP (15mg/m2) over 30 min. After 6 courses of this therapy, the serum AFP and TPA returned to normal, and the size of the metastatic para-aortic lymph nodes reduced. The effect of this therapy was judged as PR and the toxicity of this regimen was tolerable. The patient has undergone 10 courses of this therapy and is maintaining a clinical PR. The patient was able to resume his full social activities. TXL, CPT-11 and CDDP combination chemotherapy may be useful and safe for patients with recurrent gastric cancer, even after first-or second-line therapy with S-1 or taxanes.
