Although gastric cancers (GCs) with rhabdoid features are rare, they are known to show a poorer prognosis compared with conventional GCs. Indeed, more than half of reported GCs with rhabdoid features died within 6 months after receiving any kind of initial treatment. Obviously, no effective chemotherapy has been reported. In this study, we present a case of GC with rhabdoid features which showed a better response to a chemotherapy, S-1/CDDP, and lived for over 12 months after the initial chemotherapy. A 75-year-old man was seen in our hospital for epigastralgia. Detailed examinations revealed that he had GC at Stage IV. Consequently, he underwent S-1/CDDP treatment. This treatment produced a good response for 6 months, minimizing the size of the primary tumor and eradicating distant metastases. Re-growth of the primary tumor without uprising distant metastasis was confirmed 8 months after the initial S-1/CDDP treatment, and the patient went through a gastrectomy for curative care. After surgery, a precise pathological examination revealed that the primary tumor possessed a poorly differentiated adenocarcinoma that contained tumor cells with typical rhabdoid features. In the end, the patient died of liver metastasis 13 months after the initial S-1/CDDP chemotherapy. Source
