Li CG, Zhou ZP, Tan XL, Zhao ZM. Perineural invasion of hilar cholangiocarcinoma in Chinese population: One center’s experience. World J Gastrointest Oncol 2020; 12:457-466. [PMID: 32368323 PMCID: PMC7191337 DOI: 10.4251/wjgo.v12.i4.457] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Revised: 01/29/2020] [Accepted: 02/18/2020] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Hilar cholangiocarcinoma (HCCA) often produces perineural invasion (PNI) extending to extra-biliary sites, while significant confusion in the incidence of PNI in HCCA has occurred in the literature, and the mechanism of that procedure remains unclear.
AIM To summarize the incidence of PNI in HCCA and to provide the distribution of nerve plexuses around hepatic portal to clinical surgeons.
METHODS Reported series with PNI in HCCA since 1996 were reviewed. A clinicopathological study was conducted on sections from 75 patients with HCCA to summarize the incidence and modes of PNI. Immunohistochemical stains for CD34 and D2-40 in the cancer tissue were performed to clarify the association of PNI with microvessel and lymph duct. Sections of the hepatoduodenal ligament from autopsy cases were scanned and handled by computer to display the distribution of nerve plexuses around the hepatic portal.
RESULTS The overall incidence of PNI in this study was 92% (69 of 75 patients), while the rate of PNI in HCCA in the literature ranging from 38% to 100%. The incidence of PNI did not show any remarkable differences among various differentiated groups and Bismuth-Corlette classification groups. Logistic regression analysis identified the depth of tumor invasion was the only factor that correlated significantly with PNI (P < 0.01). In spite of finding tumor cells that could invade microvessels and lymph ducts in HCCA, we did not find tumor cells invaded nerves via microvessels or lymph ducts. Three nerve plexuses in the hepatoduodenal ligament and Glisson’s sheath were classified, and they all surrounded the great vessels very closely.
CONCLUSION The incidence of PNI of HCCA in Chinese population is around 92% and correlated significantly with a depth of tumor invasion. It also should be considered when stratifying HCCA patients for further treatment.

Abstract
Objective Klatskin tumors are rare, malignant tumors of the biliary system with a poor prognosis for patient survival. The current understanding of these tumors is limited to a small number of case reports or case series; therefore, we examined prognostic factors of this disease. Methods A population cohort study was conducted in patients selected from the Surveillance, Epidemiology, and End Results (SEER) database with a Klatskin tumor that was histologically diagnosed between 2004 to 2014. Propensity-matching (PSM) analysis was performed to determine the overall survival (OS) among those with a Klatskin tumor (KCC), intrahepatic cholangiocarcinoma (ICCA), or hepatocellular carcinoma (HCC). The nomogram was based on 317 eligible Klatskin tumor patients and its predictive accuracy and discriminatory ability were determined using the concordance index (C-index). Results Kaplan-Meier analysis showed that patients with Klatskin tumors had significantly worse overall survival rates (1-year OS = 26.2%, 2-year OS = 10.7%, 3-year OS = 3.4%) than those with intrahepatic cholangiocarcinoma (1-year OS = 62.2%, 2-year OS = 36.4%, 3-year OS = 19.1%, p < 0.001) or hepatocellular carcinoma (1-year OS = 72.4% , 2-year OS = 48.5%, 3-year OS = 36.2%, p < 0.001). A poor prognosis was also significantly associated with older age, higher grade, SEER historic stage, and lymph node metastasis. Local destruction of the tumor (HR = 0.635, 95% CI [0.421–0.956], p = 0.03) and surgery (HR = 0.434, 95% [CI 0.328–0.574], p < 0.001) were independent protective factors. Multivariate Cox analysis showed that older age, SEER historic stage, and lymph node metastases (HR = 1.468, 95% CI [1.008–2.139], p = 0.046) were independent prognostic factors of poor survival rates in Klatskin tumor patients, while cancer-directed surgery was an independent protective factor (HR = 0.555, 95% CI [0.316–0.977], p = 0.041). The prognostic and protective factors were included in the nomogram (C-index for survival = 0.651; 95% CI [0.607–0.695]). Conclusions The Klatskin tumor group had poorer rates of OS and cancer-specific survival than the ICCA and HCC groups. Early detection and diagnosis were associated with a higher rate of OS in Klatskin tumor patients.

Abstract
BACKGROUND/AIMS Perihilar cholangiocarcinoma is a rare disease with unfavorable prognosis resulting in low survival rates. This study aims to retrospectively assess the beneficial histopathological features and surgical procedures in long-term survivors (i.e., patients surviving perihilar cholangiocarcinoma for at least 2 y). MATERIAL AND METHODS In total, 322 patients with perihilar cholangiocarcinoma underwent surgery at our center. The follow-up ended in 2017; 76 patients survived for >2 y. The type of resection, UICC stage, and histopathological features were compared between three survival groups (>2-3, >3-5, and >5 y). RESULTS The >5-year-survival rate in our selected study cohort was 43.4% (>3-5 y,31.6% and >2-3 y, 25.0%), and 14.5% of the patients survived for >10 y after surgery. Patients with non-regional lymph node positive tumors and/or distant metastasis (i.e., UICC stage IVb; p=0.0112), R2 status (p=0.0288), and exploratory laparotomy only (p=0.0157) showed the poorest survival rates. Perineural invasion had no significant impact on the overall survival. However, 29.0% patients surviving for >5 y displayed the lowest perineural infiltration prevalence. Interestingly, Bismuth-Corlette stage IIIa (p=0.0467), especially caudate lobectomy (p=0.0034), was associated with disease-specific overall survival of >5y. CONCLUSION Complete/extended tumor resection with additional caudate lobe resection is strongly associated with long-term survival. Perineural infiltration as a negative prognostic marker for prolonged survival needs to be evaluated in larger study cohorts.

Liver transplantation for hilar cholangiocarcinoma: A systematic review. Transplant Rev (Orlando) 2019; 34:100516.

Abstract
Patients with hilar cholangiocarcinoma (hCCA) have advanced disease at presentation and therefore curative treatment options are limited. Liver transplantation (LT), in the case of unresectable disease, is theoretically an attractive option, as it offers the maximum resection margin and at the same time removes the underlying parenchymal liver disease. In the past years a number of studies have aimed to evaluate to potential beneficial role of neo adjuvant therapy followed by LT for treating patients with unresectable hCCA. The objective of our systematic review was to collect and evaluate long-term outcomes of patients with hCCA undergoing LT. A systematic search of 4 electronic databases (Medline, Scopus, Google Scholar and ClinicalTrails.gov databases) was performed for articles published between January 2000 and May 2019. A total of 13 studies with 698 patients were finally included in the present systematic review. A proportion of 74.4% of patients received combination of chemotherapy and radiation as a part of neoadjuvant therapy. One-, 3- and 5-year overall survival rates ranged greatly among the included studies from 58% to 92%, 31% to 80% and 20% to 74%, respectively. Recurrence rates ranged from 16% to 61%, whilst perioperative mortality ranged from 0% to 25.5%. LT could provide acceptable long-term outcomes in the setting of neoadjuvant chemoradiation and strict patient selection criteria. Taking into account organ shortage, combined with the lack of level I evidence, more prospective randomized trials are needed in order to establish certain indications, rigorous criteria and standardized protocols for LT in hCCA and provide the maximal potential benefits for these patients.

Abstract
Until the 1980's, Klatskin tumors were considered 'desperate cases' and most of them were not resected; almost no oncologic concept was available. After many improvements, today, extended hepatectomy, including caudate lobe resection and lymphoadenectomy, have become a standard of care for oncologicaly radical resection of Klatskin tumors. Portal vein en bloc resection, if necessary, is a diffused standard assuring R0-resection without any improvement of survival in most series. Arterial resection remains episodical and controversial in its oncologic impact. Arterial resection-reconstruction was demonstrated to be feasible with many different technical possibilities. Neoadjuvant chemotherapy, refinement of associating liver partition and portal vein ligation for staged hepatectomy and liver transplantations are some possible future resources for treatment of those aggressive tumors that could be able to expand the pool of treatable patients.

Abstract
BACKGROUND The incidence of intrahepatic cholangiocarcinoma (ICC) is increasing worldwide. Surgical resection is the only curative treatment option. AIM OF THE STUDY This study analyzed the prognostic factors after resection of ICC. MATERIAL AND METHODS A total of 84 patients were surgically treated under potentially curative intent. Perihilar and distal cholangiocarcinomas were excluded. The 5‑year survival was analyzed with respect to tumor stage (TNM), number of lesions, complete surgical resection (R0), peritoneal carcinosis and postoperative complications. RESULTS The 5‑year survival was 27% and 77% of patients underwent R0 resections. In the univariate analysis a T stage >2, an N+ situation or an R+ resection as well as peritoneal and multilocular intrahepatic spread were associated with a poorer prognosis. Postoperative complications also negatively influenced survival. On multivariate analysis the absence of peritoneal spread, node-negative tumor stages, singular hepatic lesions and a low T stage as well as the absence of complications were associated with improved survival. DISCUSSION The prognosis of ICC is poor even after successful surgical resection. Well-known tumor characteristics such as TNM are relevant prognostic factors. Surgical resection is accompanied by postoperative complications (most frequently biliary), which negatively influence survival. Adjuvant strategies are urgently needed to improve long-term survival even after complete surgical resection.

Abstract
Klatskin's tumors, actually-redefined as perihilar cholangiocarcinoma (phCCA) do represent 50-70% of all CCAs and develop in a context of chronic inflammation and cholestasis of bile ducts. Surgical resection provides the only chance of cure for this disease but is technically challenging because of the complex, intimate and variable relationship between biliary and vascular structures at this location. Five years survival rates range between 25-45% (median 27-58 months) in case of R0 resection and 0-23% (median 12-21 months) in case of R1 resection respectively. It should be noted that the major costs of high radicality are represented by relative high morbidity and mortality rates (i.e., 20-66% and 0-9% respectively). Considering the fact that radical resection may represent the only curative treatment of phCCA, we focused our review on surgical planning and techniques that may improve resectability rates and outcomes for locally advanced phCCA. The surgical treatment of phCCA can be successful when following aspects have been fulfilled: (I) accurate preoperative diagnostic aimed to identify the tumor in all its details (localization and extension) and to study all the risk factors influencing a posthepatectomy liver failure (PHLF): i.e., liver volume, liver function, liver quality, haemodynamics and patient characteristics; (II) High end surgical skills taking in consideration the local extension of the tumor and the vascular invasion which usually require an extended hepatic resection and often a vascular resection; (III) adequate postoperative management aimed to avoid major complications (i.e., PHLF and biliary complications). These are technically challenging operations and must be performed in a high volume centres by hepato-biliary-pancreas (HBP)-surgeons with experience in microsurgical vascular techniques.
