Development and Validation of a Nomogram for Differentiating Combined Hepatocellular Cholangiocarcinoma From Intrahepatic Cholangiocarcinoma

Abstract: ObjectivesTo establish a nomogram based on preoperative laboratory study variables using least absolute shrinkage and selection operator (LASSO) regression for differentiating combined hepatocellular cholangiocarcinoma (cHCC) from intrahepatic cholangiocarcinoma (iCCA).MethodsWe performed a retrospective analysis of iCCA and cHCC patients who underwent liver resection. Blood signatures were established using LASSO regression, and then, the clinical risk factors based on the multivariate logistic regression and… Show more

“…As another important part of the AJCC staging system, LNM was identified in 85 (11.5%) patients in this study, similar to previous studies (8.6%–21.4%) [ 1 , 12 , 14 , 23 , 37 42 ]. The incidence of LNM in CHC patients was higher than that of HCC patients (3.1%–4.9%) [ 43 45 ] but lower than that of ICC patients (22.6%–45.2%) [ 46 49 ].…”

“…e American Joint Committee on Cancer (AJCC) classifies CHC and ICC under the same category in the 8 th edition staging system. However, some studies have pointed out the sufficient differences in clinical features and outcomes between CHC and ICC, indicating that CHC should be considered as a separate entity for a unique staging system [11][12][13][14]. During the follow-up period, various events, socalled competing risks, may either hinder the observation or modify the occurrence chance of events of interest, including accidents and comorbidities.…”

“…In addition, the current American Joint Committee on Cancer (AJCC) staging system (8 th edition) classifies CHC and ICC into the same category. However, many studies have pointed out sufficient differences between the 2 cancers, indicating that CHC should be considered a separate entity to be evaluated independently (14,(24)(25)(26)(27). Therefore, several researchers have refocused on the therapeutic value of LT in CHC patients and obtained some contradictory results (18,19,(28)(29)(30)(31)(32).…”

“…However, many studies have shown that several independent risk factors, including age (23), race (5,9), alpha-fetoprotein (AFP) status (23), cirrhosis (4), and treatment strategies (1,5,9,(24)(25)(26), affect the survival and prognosis of patients with CHC. At present, some singlecenter studies have constructed many nomogram prediction models for CHC (22,(27)(28)(29)(30). Furthermore, studies have recently used the Surveillance, Epidemiology, and End Results (SEER) database to describe incidence trends and clinical outcomes of patients with CHC (1, 5); however, there was a lack of a nomogram to predict long-term survival.…”
