Background Major vascular involvement (IVC or portal vein) for intrahepatic cholangiocarcinoma (ICC) has traditionally been considered a contraindication to resection. We sought to define perioperative outcomes and survival of ICC patients undergoing hepatectomy with major vascular resection in a large international multi-institutional database. Methods A total of 1087 ICC patients who underwent curative-intent hepatectomy between 1990 and 2016 were identified from 13 institutions. Multivariable logistic and cox regressions were used to determine the impact of major vascular resection on perioperative and survival outcomes. Results Of 1087 patients who underwent resection, 128 (11.8%) also underwent major vascular resection (21 [16.4%] IVC resections, 98 [76.6%] PV resections, 9 [7.0%] combined resections). Despite more advanced disease, major vascular resection was not associated with the risk of any complication (OR = 0.68, 95%CI 0.32-1.45) or major complications (OR = 0.95, 95%CI 0.49-2.00). Post-operative mortality was also comparable between groups (OR = 1.05, 95%CI 0.32-3.47). In addition, median recurrence-free (14.0 vs 14.7 months, HR = 0.737, 95%CI 0.49-1.10) and overall (33.4 vs 40.2 months, HR = 0.71, 95%CI 0.359-1.40) survival were similar among patients who did and did not undergo major vascular resection (both P > 0.05). Conclusion Among patients with ICC, major vascular resection was not associated with worse perioperative or oncologic outcomes. Concurrent major vascular resection should be considered in appropriately selected patients with ICC undergoing hepatectomy.

Background While mortality in the United States has decreased for most cancers, mortality from combined hepatocellular liver cancer and intrahepatic cholangiocarcinoma (ICC) has increased and ranked 1st in annual percent increase among cancer sites. Because reported statistics combine ICC with other liver cancers, mortality rates of cholangiocarcinoma (CCA) remain unknown. This study is to determine CCA mortality trends and variation based on national data.

Background Regret-based decision curve analysis (DCA) is a framework that assesses the medical decision process according to physician attitudes (expected regret) relative to disease-based factors. We sought to apply this methodology to decisions around the operative management of intrahepatic cholangiocarcinoma (ICC). Methods Utilizing a multicentric database of 799 patients who underwent liver resection for ICC, we developed a prognostic nomogram. DCA tested 3 strategies: (1) perform an operat...

Abstract Complete surgical resection is the only curative-intent therapy for patients with hilar cholangiocarcinoma, and obtaining negative pathologic margins is crucial to allow for prolonged disease-free survival. Macrovascular tumor invasion adds technical complexity to surgical extirpation, but can be achieved with en bloc vessel resection. This tumor extension adversely affects overall prognosis, but is nonetheless technically feasible. Several recent meta-analyses have studied the short an...

Cholangiocarcinoma (CCA) is an aggressive malignancy of the biliary tract. To date, surgical treatment remains the only hope for definitive cure of CCA patients. Involvement of major vascular structures was traditionally considered a contraindication for resection. Nowadays, selected cases of CCA with vascular involvement can be successfully approached. Intrahepatic CCA often involves the major hepatic veins or the inferior vena cava and might necessitate complete vascular exclusion, in situ hyp...

The oncological role of the density of nerve fibers (NFs) in the tumor microenvironment (TME) in intrahepatic cholangiocarcinoma (iCCA) remains to be determined. Therefore, data of 95 iCCA patients who underwent hepatectomy between 2010 and 2019 was analyzed regarding NFs and long-term outcome. Extensive group comparisons were carried out and the association of cancer-specific survival (CSS) and recurrence-free survival (RFS) with NFs were assessed using Cox regression models. Patients with iCCA...

Intrahepatic cholangiocarcinoma (iCCA) is a subgroup of cholangiocarcinoma that accounts for about 10%-20% of the total cases. Infection with hepatitis B virus (HBV) is one of the most important predisposing factors leading to the formation of iCCA. It has been recently estimated based on abundant epidemiological data that the association between HBV infection and iCCA is strong with an odds ratio of about 4.5. The HBV-associated mechanisms that lead to iCCA are under intense investigation. The ...
The only curative treatment option for intrahepatic cholangiocarcinoma (iCCA) is liver resection. Due to central tumor localization and vascular invasion, complex liver resections play an important role in curative treatment. However, the long-term outcomes after complex liver resection are not known. Methods: A retrospective cohort study was conducted for all patients undergoing liver surgery for iCCA. Complex liver resections included ante situm resections, associating liver partition and port...

Intrahepatic cholangiocarcinoma (ICC) is a rare, aggressive cancer of the biliary tract. It often presents with locally advanced or metastatic disease, but for patients with early-stage disease, surgical resection with negative margins and portahepatis lymphadenectomy is the standard of care. Recent advancements in ICC include refinement of staging, improvement in liver-directed therapies, clarification of the role of adjuvant therapy based on new randomized controlled trials, and advances in mi...

Background Intrahepatic cholangiocarcinoma (ICC) is the second most common liver primary tumour after hepatocellular carcinoma and represents 20% of all the cholangiocarcinomas. Its incidence is increasing and mortality rates are rising. Surgical resection is the only option to cure the disease, despite the high recurrence rates reported to be up to 80%. Intrahepatic recurrences may be still treated with curative intent in a small percentage of the patients. Unfortunately, due to lack of specifi...
