Surgical resection is considered first-line treatment for intrahepatic cholangiocellular carcinoma (ICC).
In case of a unresectable tumor, chemotherapy is part of standardized treatment guidelines, despite dismal outcome. Technical advances in locoregional therapies such as radiofrequency ablation, microwave ablation, irreversible electroporation, transarterial chemoembolization and selective internal radiation therapy bear the promise for enhancing local tumor control, while reducing treatment associated morbidity and improving survival as well asquality of life.

Read article Background: There has been a debate as to the extent of hepatic resection for T2 gallbladder cancer. While some surgeons advocate resection of the segments 4a and 5, gallbladder bed resection is also performed by others.
A fluorescent imaging technique with selective injection of indocyanine green can provide real-time anatomic guidance within the operative field for hepatobiliary surgery.
This study was performed to evaluate the usefulness of fluorescent navigation surgery for gallbladder cancer.

Methods: Four patients underwent fluorescent navigati....[more]

Article DOI: 10.21614/sgo-23-5-314
Read article Background Aims: Hepatic surgical resection is one of the most effective treatment for hepatocellular carcinoma (HCC). However, recurrence of HCC (HCCR) is still very common among operated patients, and its risk factors still remains unclear.

Materials and Methods: We have conducted a retrospective study of 56 patients operated for HCC in our medical center during April 2008 through March 2016, to analyze the risk factors for HCCR. The ideal cutoff values of laboratory parameters was defined using the Receiver Operating Characteristic (ROC) curve analysis, and....[more]

Article DOI: 10.21614/sgo-23-5-320
Read article Background: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is performed for diagnosing pancreatic lesions. As EUS-FNA can develop needle track seeding, its use for radiographically-diagnosed pancreatic malignancy remains controversial.
We investigated a useful setting of EUS-FNA for resectable pancreatic adenocarcinoma by comparing the diagnostic sensitivity between EUS-FNA and contrast enhanced-computed tomography (CT), and by evaluating the short- and long-term outcomes.

Methods: Between January 2012 and March 2015, 107 consecutive patie....[more]

Read article Background Aims: The aim of this study is to evaluate long-term outcome of 3-week method (3-week administration followed by 1-week rest) for colorectal cancer as adjuvant chemotherapy with an oral anticancer drug, S-1.

Methods: Between 2008 and 2012, 142 patients with stage III colorectal cancer who underwent curative resection in our hospital and received oral adjuvant chemotherapy with S-1 for six months were enrolled in this study.
They were divided into two groups, 3-week method or 4-week method (4-week administration followed 2-week rest).
