Intrahepatic cholangiocarcinoma (ICC) has a poor prognosis, as the resectability rate is low due to its diagnosis at a late/advanced stage. Moreover, most patients with resected ICC eventually relapse. Hepatic arterial infusion chemotherapy (HAIC) has been indicated only by a few reports to be effective in patients with advanced ICC; thus, its efficacy for these patients remains unclear. This study aimed to evaluate the efficacy of HAIC using gemcitabine, cisplatin, and 5-fluorouracil in patients with advanced ICC. A total of 18 patients who underwent HAIC were retrospectively investigated. The patients received gemcitabine, cisplatin, and 5-fluorouracil through one artery. In patients who received gemcitabine plus cisplatin (n = 10), the response and disease control rates were 0% and 80.0%, respectively; the median overall survival (OS) and progression-free survival (PFS) after treatment initiation were 6.3 and 3.7 months, respectively. In patients who never received chemotherapy (n = 8), the response and disease control rates were 37.5% and 75%, respectively; the median OS and PFS were 20.6 and 8.1 months, respectively. Moreover, we compared the patients who received HAIC using gemcitabine, cisplatin, and 5-fluorouracil to patients whose tumors were refractory to systemic gemcitabine and cisplatin therapy. The OS of the patients who received HAIC was better than that of the patients who received standard chemotherapy cohort since the gemcitabine plus cisplatin combination therapy-refractory response and disease onset (P = 0.045, 0.006). HAIC using gemcitabine, cisplatin, and 5-fluorouracil may be effective as a therapeutic option for patients with advanced ICC.

We aimed to evaluate the efficacy and safety of 5-fluorouracil-based neoadjuvant chemoradiotherapy (NACRT) in patients with resectable/borderline resectable pancreatic ductal adenocarcinoma (PDAC). This retrospective study investigated the clinicopathological features and > 5-year survival of patients with T3/T4 PDAC who underwent NACRT at our institute between 2003 and 2012. Seventeen resectable and eight borderline resectable patients were included. The protocol treatment completion and resection rates were 92.0% and 68.0%, respectively. Two patients failed to complete chemotherapy owing to cholangitis or anorexia. Common grade 3 toxicities included anorexia (12%), neutropenia (4%), thrombocytopenia (4%), anemia (4%), and leukopenia (12%). Pathologically negative margins were achieved in 94.1% of patients who underwent pancreatectomy. Pathological response according to Evans’ classification was grade IIA in 10 patients (58.8%), IIB in 5 patients (29.4%), and IV in 2 patients (11.8%). Postoperative pancreatic fistulas were observed in four patients (23.5%), delayed gastric emptying in one patient (5.9%), and other operative morbidities in four patients (23.5%). The 1-, 2-, 5-, and 10-year overall survival rates were 73.9%, 60.9%, 60.9%, and 39.1%, respectively (median follow-up period, 80.3 months). NACRT is tolerable and beneficial for resectable/borderline resectable PDAC, even in the long-term.
