[A case of long-term survival following combined modality therapy for peritoneal disseminated recurrence of duodenal cancer].

A 65-year-old man was diagnosed with primary duodenal cancer and he underwent pancreaticoduodenectomy in June 2006. S-1 was administered as the postoperative adjuvant chemotherapy. A peritoneal disseminated recurrence was diagnosed together with a right reniportal node and right hydronephrosis in February 2007. A ureteral stent was inserted. DOC +S-1 combination therapy was administered from March 2007. Following progression of the recurrence, CDDP+S-1 combination therapy was administered from August 2007. Temporal diminution of the recurrence was achieved with radiotherapy from May to June 2009. Following re-progression of the recurrence, biweekly CPT-11 therapy was administered from February 2010. Weekly PTX therapy was administered from January 2011. The patient died due to progression of the recurrence in June 2011, 5 years after the operation. Our patient maintained a good quality of life and achieved long-term survival by combined modality therapy for peritoneal disseminated recurrence of duodenal cancer.
