A 69-year-old woman with unresectable intrahepatic cholangiocarcinoma(T3N1M1, Stage Ⅳ)underwent chemoradiotherapy with gemcitabine, cisplatin and irradiation toward primary lesion(total dose, 36 Gy). Grade 3 or 4 adverse events include leukopenia, neutropenia, and anemia. The relative dose intensities at 6 months after beginning of treatment were 58.9%(gemcitabine)and 80.2%(cisplatin), respectively. The total dose of administered cisplatin was 525 mg to the square meter. Partial response was obtained, and after that, the representative lesions have been stable with continuous administration of gemcitabine. As some studies have reported clinical benefits of chemoradiotherapy for unresectable intrahepatic cholangiocarcinoma, further clinical investigations are expected.

surgery and autotransplantation may provide a promising option for radical resection of conventionally unresectable liver tumors. Two cirrhotic patients with hepatocellular carcinoma (HCC), which has an "awkward seat" located in the "intrahepatic vascular triangle area (IVTA)" that consists of the middle hepatic vein (MHV), the right branches of the Glisson sheath, and the inferior vena cava (IVC), underwent extended right-half hepatectomy followed by tumor resection and partial liver autotransplantation. Innovatively, the outflow of the tumor-free liver was reconstructed using pre-frozen allograft blood vessels from brain-dead donors; the patients recovered well postoperation.

Surgical resection is the only curative treatment for cholangiocarcinoma, but it is often diagnosed at advanced stages, making surgical resection infeasible. Recently, the concept of conversion surgery has expanded the indications for surgical treatment, thanks to advancements in both perioperative management and chemotherapy. However, it remains unclear which patients benefit most from this treatment strategy.

Purpose: This study aimed to develop and validate clinical nomograms for predicting progression-free survival (PFS) and overall survival (OS) in unresectable ICC patients.
Patients And Methods: Patients with ICC between 1 January 2018 and 31 May 2023 were selected and randomized into a training set and an internal validation set as a 7:3 ratio. Data analysis and modeling were conducted through R software.

Purpose: To validate the safety and efficacy of radiation segmentectomy (RS) and modified radiation lobectomy (mRL) in intrahepatic cholangiocarcinoma (iCCA) and to evaluate long-term outcomes in patients with unresectable, early-stage iCCA.
Materials And Methods: A single-institution, retrospective study of patients with unresectable, solitary iCCA without extrahepatic disease or vascular involvement (stage I) treated with RS and mRL was performed. Fifteen patients met inclusion criteria (median age 65.

Liver cancer ranks as the sixth most prevalent form of cancer and stands as the fourth leading cause of cancer-related fatalities on a global scale. The two primary types of liver cancer are hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). While ICC originates from the bile ducts, HCC develops from hepatocytes, which are the primary functional cells of the liver.
