Hepatic artery AND perihilar cholangiocarcinoma

Prognostic features in advanced perihilar cholangiocarcinoma (pCCA) patients who received first-line hepatic arterial infusion chemotherapy (HAIC) are unknown. The purpose of our study was to develop an applicable score based on serum inflammatory-tumor biomarkers to predict the survival of advanced pCCA patients who received first-line HAIC. In total, 106 advanced pCCA patients were enrolled as the training cohort. The optimal cutoff values of baseline variables were defined by the receiver operating characteristic method or according to previous publications...

Primary hepatobiliary cancers (PHCs), which mainly include hepatocellular carcinoma (HCC) and biliary tract cancers (BTCs), are mostly diagnosed in the advanced stage and are not candidates for curative surgery or ablation, resulting in a dismal prognosis. Targeted therapies with or without programmed death receptor 1 (PD-1)/PD-L1 inhibitors have been incorporated into first-line treatments for advanced HCC. Systemic chemotherapy is still the mainstay treatment for advanced BTCs, and combining it with PD-1/PD-L1 inhibitors has resulted in prolonged patient survival...

BACKGROUND: Advanced hepatobiliary-pancreatic cancer often invades critical blood vessels, including the portal vein (PV) and hepatic artery. Resection with tumor-free resection margins is crucial to achieving a favorable prognosis in these patients. Herein, we present our cases and surgical techniques for PV wedge resection with patch venoplasty using autologous vein grafts during surgery for pancreatic ductal adenocarcinoma (PDAC) and perihilar cholangiocarcinoma (PhCC). CASE PRESENTATION: Case 1: 73-year-old female patient with PDAC; underwent subtotal stomach-preserving pancreatoduodenectomy, with superior mesenteric vein wedge resection and venoplasty with the right gonadal vein...

BACKGROUND: The application of three-dimensional (3D) reconstruction has been extensively adopted in hepatectomy navigation,1 yet its utilization in laparoscopic radical resection of perihilar cholangiocarcinoma (pHCCA) remains underexplored. VIDEO: A 54-year-old male patient, classified as Child-Pugh B, presented a small neoplasm situated at the left hepatic duct proximate to the right hepatic and common hepatic ducts. An enhanced abdominal computed tomographic scan identified a solitary lesion measuring 2...

BACKGROUND: The relationship between the course of the segment 4 hepatic artery and proximal ductal margin status in the right hepatectomy (H15678-B) for perihilar cholangiocarcinoma is unclear. This study aimed to evaluate proximal ductal margin status according to the course of the segment 4 hepatic artery in patients with perihilar cholangiocarcinoma treated with right hepatectomy. METHODS: Consecutive patients with perihilar cholangiocarcinoma who underwent a right hepatectomy between January 2006 and August 2021 were retrospectively reviewed...

BACKGROUND: Perihilar cholangiocarcinoma (pCCA) is a highly malignant tumor arising from the biliary tree. Radical surgery is the only treatment offering a chance of long-term survival. However, limited by the tumor's anatomic location and peri-vascular invasion, most patients lose the chance for curative treatment. Therefore, more methods to increase the resectability of tumors as well as to improve outcomes are needed. CASE SUMMARY: A 68-year-old female patient had a hepatic hilar mass without obvious symptoms...

BACKGROUND: The benefits of lymph node (LN) dissection at each station have not previously been fully investigated in perihilar cholangiocarcinoma (PHCC) and distal cholangiocarcinoma (DCC). METHODS: The efficacy index (EI) was calculated in patients who underwent surgery for PHCC (n = 134) and DCC (n = 135) by multiplying the frequency of metastasis to the LN station and the 5-year overall survival (OS) rate of patients with metastasis to that station...

INTRODUCTION: Minimally invasive resection for perihilar cholangiocarcinoma is an emerging technique that requires both mastery in minimally invasive liver resection and biliary reconstruction. Due to technical difficulties in biliovascular dissection, radical portal lymphadenectomy and the need for fine suturing during bilioenteric anastomosis, this type of resection is generally not performed laparoscopically, even at high-volume, liver-surgery centers.1-3 In modern literature, a detailed, operative description of robotic technique for this operation with outcome data is lacking...

AIM: Neoadjuvant chemoradiotherapy may improve survival in patients with advanced cholangiocarcinoma. This Phase I study aimed to determine the recommended dose of neoadjuvant chemoradiotherapy and decide whether to move to a Phase II study. METHODS: Patients diagnosed with resectable stage II-IVa cholangiocarcinoma were administered cisplatin (40 [level 0], 50 [level 1 as starting dose], or 60 [level 2] mg/m2 ), 80 mg/m2 of S-1, and 50.4 Gy of external beam radiation...

PURPOSE: To evaluate the patterns of locoregional recurrence (LRR) in patients with perihilar extrahepatic cholangiocarcinoma (PEHC) treated with radical resection and to suggest the optimal target volume for elective nodal irradiation. METHODS: Medical records of PEHC patients who underwent radical resection between January 2000 and September 2021 at five institutions were reviewed. Patients who were confirmed with LRR in the follow-up imaging study were included...

TECHNIQUE: Hepatoduodenal ligamentectomy (HL) is a challenging surgery for advanced perihilar cholangiocarcinoma extensively invading the hepatoduodenal ligament1-3 . A liver-transection first approach in HL is a no-touch technique wherein liver transection is performed first, and the affected liver and hepatoduodenal ligament are removed en bloc. This approach allows for the early assessment of resectability and feasibility of vascular reconstruction4 . RESULTS: This video shows a 57-year-old man with advanced intrahepatic cholangiocarcinoma in the left hepatic lobe, which had directly invaded the perihilar region and the hepatoduodenal ligament via lymph node metastasis...

BACKGROUND: The definition and classification of regional nodes are not standardized for perihilar cholangiocarcinoma. This study aimed to clarify the rational extent of regional lymphadenectomy and to elucidate the impact of number-based regional nodal classification on survival of patients with this disease. METHODS: Data of 136 patients with perihilar cholangiocarcinoma who underwent surgery were reviewed. The incidence of metastasis and the survival of patients with metastasis were calculated for each node group...

Objective: To investigate surgical strategies and the corresponding benefits for patients with perihilar cholangiocarcinoma(pCCA). Methods: A total of 81 patients with pCCA who underwent radical excision in the Department of Biliary and Pancreatic Surgery of Sun Yat-Sen Memorial Hospital between January 2014 and December 2021 were retrospectively collected.The cohort consisted of 50 male and 31 female patients,with an age of (62.5±11.5)years(range:26 to 83 years).Seventy-five cases were diagnosed with jaundice,60 of whom received preoperative biliary drainage,while 20 patients received portal vein embolization...

BACKGROUND: The risk of death after surgery for perihilar cholangiocarcinoma is high; nearly one in every five patients dies within 90 days after surgery. When the oncological benefit is limited, a high-risk resection may not be justified. This retrospective cohort study aimed to create two preoperative prognostic models to predict 90-day mortality and overall survival (OS) after major liver resection for perihilar cholangiocarcinoma. METHODS: Separate models were built with factors known before surgery using multivariable regression analysis for 90-day mortality and OS...

BACKGROUND: Perihilar cholangiocarcinoma (pCCA) is often unresectable, because it includes crucial blood vessels in portal area. The prognosis of locally advanced unresectable cholangiocarcinomas is extremely poor. Recently, there have been several reports of the prognosis improving drastically with transplantation and combined chemoradiation therapy. However, liver transplantation for pCCA has 2 big problems. The first is that pCCA is located at a lethal position and its progress is sometimes rapid; therefore, the optimal timing of transplantation is sometimes lost...

How the side of an extended liver resection impacts the postoperative prognosis of advanced perihilar cholangiocarcinoma (PHC) is still controversial. We compared the outcomes of right (RTS) and left trisectionectomies (LTS) in Bismuth-Corlette (BC) type IV PHC resection. All patients undergoing RTS or LTS for BC type IV PHC in a single tertiary center between January 2012 and December 2019 were compared retrospectively. The endpoints were perioperative outcomes, long-term overall (OS), and disease-free survival (DFS)...

Perihilar cholangiocarcinoma (PHCC) is one of the most intractable gastrointestinal malignancies. These tumours lie in the core section of the biliary tract. Patients who undergo curative surgery have a 40-50-month median survival time, and a five-year overall survival rate of 35-45%. Therefore, curative intent surgery can lead to long-term survival. PHCC sometimes invades the surrounding tissues, such as the portal vein, hepatic artery, perineural tissues around the hepatic artery, and hepatic parenchyma. Contralateral hepatic artery invasion is classed as T4, which is considered unresectable due to its "locally advanced" nature...

Portal vein arterialization (PVA) in advanced cholangiocarcinoma (CCA) is an emerging field of study too little explored despite its potential oncological results. Still to this day, advanced CCA, including peri-hilar (pCCA) and distal (dCCA) CCA, represents a surgical challenge. At diagnosis, CCA is typically associated with extensive infiltration of hilar structures often requiring extended liver and vascular resections that lead to technically complex biliary reconstructions and vascular anastomosis. The rationale behind such radical surgery is to ensure complete tumor resection, with negative margins at final pathology, which remains the only potential curative option...

Complete resection of perihilar cholangiocarcinoma (pCCA) is the only potentially curative treatment. Long-term survival data is rare and prognostic analyses are hindered by the rarity of the disease. This study aimed to determine the cure rate and to identify clinicopathological factors that may preclude cure. All consecutive resections for pathologically confirmed pCCA between 2000 and 2009 in 22 centers worldwide were included in a retrospective cohort study. Each center included its retrospective data series...
