[A case of S-1-resistant resected advanced gastric cancer with para-aortic lymph node recurrence responding to bi-weekly CPT-11 and CDDP].

A 64-year-old man with advanced gastric cancer who underwent a curative total gastrectomy(LM, Less, Type 3, 70×55 mm, por1>tub2>sig, pT3(ss), med, INF b, ly3, v3, pN3b(41/61), pPM0, pDM0, pT3N3bM0, Stage III B)followed by adjuvant chemotherapy(paclitaxel+S-1)a year ago, revealed an increasing level of serum CEA and para-aortic lymphnode (#16b1)recurrence on abdominal CT. He was given chemotherapy with low-dose weekday CDDP+S-1 for the recurrence, after which he failed to respond. Thereafter, he received 2nd-line chemotherapy with bi-weekly CPT-11+CDDP as a S-1- refractory regimen. 3 courses of the regimen reduced the serum CEA level accompanied by grade 3 of anemia. After recovery from the adverse event, another 4 courses at a 20% lower dosage for safety were administered. Complete response to the lymphnode was ensured on the abdominal CT with a reduced serum CEA level into the normal range. The patient has no signs of recurrence and has survived in fair condition for more than 5 years after the surgery. The combination treatment of biweekly CPT-11+CDDP can be a worthwhile regimen for patient with S-1-refractory recurrence of the resected advanced gastric cancer.
