A long survivor with local relapse of hilar cholangiocarcinoma after R1 surgery treated with chemoradiotherapy: a case report and literature review

Abstract

The treatment outcome of extrahepatic cholangiocarcinoma remains insufficient because it is difficult to obtain accurate diagnosis of tumor spreading and effective treatment agent is quite limited in spite of substantial current efforts, all of which have been unsuccessful except for gemcitabine plus cisplatin. The patient was a 60-year-old female who had developed hilar cholangiocarcinoma and underwent extrahepatic bile duct resection. Although it was conceivable that it would be the R1 resection, the patient wanted to receive limited resection to avoid postoperative complication mainly because she was depressed. In histology, interstitial spreading of tumor was appreciated at the surgical margin of bile duct. The patient did not accept to receive the additional treatment after the surgery and hardly visited the hospital to take the periodical test for monitoring the residual cancer cells. As expected, the local relapse of tumor was appreciated 1 year after the R1 surgery. She chose radiotherapy and agreed with subsequent S-1 treatment for 26 months. Consequently, elevated CA19-9 was decreased, and local relapse has been successfully controlled for more than 7 years after the relapse of tumor. Here, we report quite a rare case in terms of long survivor after chemoradiotherapy on locally relapsed unresectable hilar cholangiocarcinoma.

A long-term survivor of hilar cholangiocarcinoma with resection of recurrent peritoneal dissemination after R0 surgery: a case report

“…Moreover, in the case of peritoneal dissemination of HCCA, the prognosis is even worse [ 4 ]. To improve the prognosis, resection of local disease is sometimes effective together with multidisciplinary treatments such as chemotherapy, radiation therapy, or chemoradiotherapy before or after surgery [ 5 , 6 ]. However, there are few reports of long survivor of HCCA patients with recurrent disease of peritoneal dissemination after curative surgery [ 7 ].…”
