s-1-(combination) and Calcinosis

A 70-year-old woman was diagnosed with cStage IV gastric cancer with diffuse intra-tumoral calcifications. She underwent systemic chemotherapy with an S-1/cisplatin regimen. However, as the disease progressed after 5 courses of the regimen, a secondary S-1/docetaxel regimen was administered. The target lesions showed complete response after 6 courses of this regimen, and surgery with curative intent was planned. The patient underwent total gastrectomy because no factors that would compromise the curative intent were observed during laparotomy. Postoperatively, the disease showed pathological complete response to chemotherapy.

We described a case with recurrent gallbladder carcinoma, successfully treated by combination chemotherapy using gemcitabine, CPT-11, and S-1 that was administered as second-line chemotherapy after failure of gemcitabine monotherapy. The level of CA19-9 was normalized three months later, and metastatic tumors of the liver were calcified. She had received the combination chemotherapy for 15 months and is now alive.
