Abstract
BACKGROUND Accurate risk stratification and patient selection is necessary to identify patients who will benefit the most from surgery or be better treated with other non-surgical treatment strategies. We sought to identify which patients in the preoperative setting would likely derive the most or least benefit from resection of intrahepatic cholangiocarcinoma (ICC). METHODS Patients who underwent curative-intent resection for ICC between 1990 and 2017 were identified from an international multi-institutional database. A machine-based classification and regression tree (CART) was used to generate homogeneous groups of patients relative to overall survival (OS) based on preoperative factors. RESULTS Among 1146 patients, CART analysis revealed tumor number and size, albumin-bilirubin (ALBI) grade and preoperative lymph node (LN) status as the strongest prognostic factors associated with OS among patients undergoing resection for ICC. In turn, four groups of patients with distinct outcomes were generated through machine learning: Group 1 (n = 228): single ICC, size ≤ 5 cm, ALBI grade I, negative preoperative LN status; Group 2 (n = 708): (1) single tumor > 5 cm, (2) single tumor ≤ 5 cm, ALBI grade 2/3, and (3) single tumor ≤ 5 cm, ALBI grade 1, metastatic/suspicious LNs; Group 3 (n = 150): 2-3 tumors; Group 4 (n = 60): ≥ 4 tumors. 5-year OS among Group 1, 2, 3, and 4 patients was 60.5%, 35.8%, 27.5%, and 3.8%, respectively (p < 0.001). Similarly, 5-year disease-free survival (DFS) among Group 1, 2, 3, and 4 patients was 47%, 27.2%, 6.8%, and 0%, respectively (p < 0.001). CONCLUSIONS The machine-based CART model identified distinct prognostic groups of patients with distinct outcomes based on preoperative factors. Survival decision trees may be useful as guides in preoperative patient selection and risk stratification.

Abstract
BACKGROUND Clinically relevant postoperative pancreatic fistula (CR-POPF) is the most common cause of major morbidity following pancreatic resection. Intra-abdominal drains are frequently positioned adjacent to the pancreatic anastomosis or transection margin at the time of surgery to aid in detection and management of CR-POPF. Drains can either evacuate fluid by passive gravity (PG) or be attached to a closed suction (CS) system using negative pressure. There is controversy as to whether one of these two systems is superior. The objective of this review is to identify and compare the incidence of adverse events (AEs) and resource utilisation associated with PG and CS drainage following pancreatic resections. METHODS AND ANALYSIS MEDLINE, EMBASE, CINAHL and Cochrane Central Registry of Controlled Trials will be searched from inception to April 2019, to identify interventional and observational studies comparing PG and CS drains following pancreatic resection. The primary outcome is POPF as defined by the International Study Group for Pancreatic Fistula in 2017. Secondary outcomes include postoperative AE, resource utilisation (length of stay, return to emergency department, readmission and reintervention), time to drain removal and quality of life. Study selection, data extraction and risk of bias assessment will be performed independently, by two reviewers. A meta-analysis will be conducted if deemed statistically appropriate. Subgroup analysis by study design will be performed. Study heterogeneity will be calculated with the χ2 test and reported as I2 statistics. Statistical analyses will be conducted and displayed using RevMan V.5.3 ETHICS AND DISSEMINATION: Ethics approval is not required. The results of this study will be submitted to relevant conferences for presentation and peer-reviewed journals for publication. PROSPERO REGISTRATION NUMBER CRD42019123647.

Abstract
BACKGROUND The best achievable short-term outcomes after liver surgery have not been identified. Several factors may influence the post-operative course of patients undergoing hepatectomy increasing the risk of post-operative complications. We sought to identify risk-adjusted benchmark values [BMV] for liver surgery. METHODS The National Surgery Quality Improvement Program (NSQIP) database was used to develop Bayesian models to estimate risk-adjusted BMVs for overall and liver related (post-hepatectomy liver failure [PHLF], biliary leakage [BL]) complications. A separate international multi-institutional database was used to validate the risk-adjusted BMVs. RESULTS Among the 11,243 patients included in the NSQIP database, the incidence of complications, PHLF, and BL was 36%, 5%, and 8%, respectively. The risk-adjusted BMVs for complication (range, 16-72%), PHLF (range, 1%-20%), and BL (range, 4%-22%) demonstrated a high variability based on patients characteristics. When tested using an international database including nine institutes, the risk-adjusted BMVs for complications ranged from 26% (Institute-4) to 43% (Institute-1), BMVs for PHLF between 3% (Institute-3) and 12% (Institute-5), while BMVs for BL ranged between 5% (Institute-4) and 9% (Institute-7). CONCLUSIONS Multiple factors influence the risk of complications following hepatectomy. Risk-adjusted BMVs are likely much more applicable and appropriate in assessing "acceptable" benchmark outcomes following liver surgery.

Abstract
BACKGROUND Although the Barcelona Clinic Liver Cancer (BCLC) staging system has been largely adopted in clinical practice, recent studies have questioned the prognostic stratification of this classification schema, as well as the proposed treatment allocation of patients with a single large tumor. METHODS Patients who underwent curative-intent hepatectomy for histologically proven hepatocellular carcinoma (HCC) between 1998 and 2017 were identified using an international multi-institutional database. Overall survival (OS) among patients with BCLC stage 0, A, and B was examined. Patients with a single large tumor were classified as BCLC stage A1 and were independently assessed. RESULTS Among 814 patients, 68 (8.4%) were BCLC-0, 310 (38.1%) were BCLC-A, 279 (34.3%) were BCLC-A1, and 157 (19.3%) were BCLC-B. Five-year OS among patients with BCLC stage 0, A, A1, and B HCC was 86.2%, 69.0%, 56.9%, and 49.9%, respectively (p < 0.001). Among patients with very early- and early-stage HCC (BCLC 0, A, and A1), patients with BCLC stage A1 had the worst OS (p = 0.0016). No difference in survival was noted among patients undergoing surgery for BCLC stage A1 and B HCC (5-year OS: 56.9% vs. 49.9%; p = 0.259) even after adjusting for competing factors (hazard ratio 0.83, 95% confidence interval 0.54-1.28; p = 0.40). CONCLUSION Prognosis following liver resection among patients with BCLC-A1 HCC was similar to patients presenting with BCLC-B tumors. Surgery provided acceptable long-term outcomes among select patients with BCLC-B HCC. Designation into BCLC stage B should not be considered an a priori contraindication to surgery.

Abstract
Importance Composite measures may be superior to individual measures for the analysis of hospital performance and quality of surgical care. Objective To determine the incidence of a so-called textbook outcome, a composite measure of the quality of surgical care, among patients undergoing curative-intent resection of intrahepatic cholangiocarcinoma. Design, Setting, and Participants This cohort study involved an analysis of a multinational, multi-institutional cohort of patient from 15 major hepatobiliary centers in North America, Europe, Australia, and Asia who underwent curative-intent resection of intrahepatic cholangiocarcinoma between 1993 and 2015. Data analysis was conducted from April 2018 to May 2018. Main Outcomes and Measures Hospital variation in the composite end point of textbook outcome, defined as negative margins, no perioperative transfusion, no postoperative surgical complications, no prolonged length of stay, no 30-day readmissions, and no 30-day mortality. Secondary end points were factors associated with achieving textbook outcomes. Results Among 687 patients (of whom 370 [53.9%] were men; median patient age, 61 [range, 18-86] years) undergoing curative-intent resection of intrahepatic cholangiocarcinoma, a textbook outcome was achieved in 175 patients (25.5%). Being 60 years or younger (odds ratio [OR], 1.61 [95% CI, 1.04-2.49]; P = .03), absence of preoperative jaundice (OR, 4.40 [95% CI, 1.28-15.15]; P = .02), no neoadjuvant chemotherapy (OR, 2.57 [95% CI, 1.05-6.29]; P = .04), T1a/T1b-stage disease (OR, 1.58 [95% CI, 1.01-2.49]; P = .049), N0 status (OR, 3.89 [95% CI, 1.77-8.54]; P = .001), and no bile duct resection (OR, 2.46 [95% CI, 1.25-4.84]; P = .009) were independently associated with achieving a textbook outcome after resection. A prolonged length of stay had the greatest negative association with a textbook outcome. A nomogram to assess the probability of textbook outcome was developed and had good accuracy in both the training data set (area under the curve, 0.755) and validation data set (area under the curve, 0.763). Conclusions and Relevance In this study, while hepatic resection for intrahepatic cholangiocarcinoma was performed with less than 5% mortality in specialized centers, a textbook outcome was achieved in only approximately 26% of patients. A textbook outcome may be useful for the reporting of patient-level hospital performance and hospital variation, leading to quality improvement efforts after resection of intrahepatic cholangiocarcinoma.

Abstract
INTRODUCTION A significant proportion of red blood cell (RBC) transfusions are administered intraoperatively; yet there is limited evidence to guide transfusion decisions in this setting. The objective of this systematic review is to explore the availability, quality and content of clinical practice guidelines (CPGs) reporting on the indication for allogenic RBC transfusion during surgery. METHODS Major electronic databases (MEDLINE, EMBASE and CINAHL), guideline clearinghouses and Google Scholar, will be systematically searched from inception to January 2019 for CPGs pertaining to indications for intraoperative allogenic RBC transfusion. Characteristics of eligible guidelines will be reported in a summary table. The AGREE II instrument will be used to appraise the quality of identified guidelines. Recommendations advising on indications for intraoperative RBC transfusion will be manually extracted and presented to allow for comparison of similarities and/or discrepancies in the literature. ETHICS AND DISSEMINATION The results of this systematic review will be disseminated through relevant conferences and peer-reviewed journals. TRIAL REGISTRATION NUMBER CRD42018111487.

Abstract
BACKGROUND Perioperative red blood cell (RBC) transfusion is associated with poor outcomes in liver surgery. Hypovolemic phlebotomy (HP) is a novel intervention hypothesized to decrease transfusion requirements. The objective of this study was to examine this hypothesis. METHODS Consecutive patients who underwent liver resection at one institution (2010-2016) were included. Factors found to be predictive of transfusion on univariate analysis and those previously published were modeled using multivariate logistic regression. RESULTS A total of 361 patients underwent liver resection (50% major). HP was performed in 45 patients. Phlebotomized patients had a greater proportion of primary malignancy (31% vs 18%) and major resection (84% vs 45%). Blood loss was significantly lower with phlebotomy in major resections (400 vs 700 mL). Nadir central venous pressure was significantly lower with HP (2.5 vs 5 cm H2O). On multivariate logistic regression, HP (OR 0.20, 95% CI 0.068-0.57, p = 0.0029), major liver resection (OR 2.91, 95% CI 1.64-5.18, p = 0.0003), preoperative hemoglobin < 125 g/L (OR 6.02, 95% CI 3.44-10.56, p < 0.0001), and underlying liver disease (OR 2.24, 95% CI 1.27-3.95, p = 0.0051) were significantly associated with perioperative RBC transfusion. CONCLUSION Hypovolemic phlebotomy appears to be strongly associated with a reduction in RBC transfusion requirements in liver resection, independent of other known risk factors.

Abstract
BACKGROUND Recurrence of intrahepatic cholangiocarcinoma (ICC) after curative resection is common. OBJECTIVE The aim of this study was to investigate the patterns, timing and risk factors of disease recurrence after curative-intent resection for ICC. METHODS Patients undergoing curative resection for ICC were identified from a multi-institutional database. Data on clinicopathological and initial operation information, timing and first sites of recurrence, recurrence management, and long-term outcomes were analyzed. RESULTS A total of 920 patients were included. With a median follow-up of 38 months, 607 patients (66.0%) experienced ICC recurrence. In the cohort, 145 patients (23.9%) recurred at the surgical margin, 178 (29.3%) recurred within the liver away from the surgical margin, 90 (14.8%) recurred at extraheptatic sites, and 194 (32.0%) developed both intrahepatic and extrahepatic recurrence. Intrahepatic margin recurrence (median 6.0 m) and extrahepatic-only recurrence (median 8.0 m) tended to occur early, while intrahepatic recurrence at non-margin sites occurred later (median 14.0 m; p < 0.05). On multivariate analysis, surgical margin < 10 mm was associated with increased margin recurrence (hazard ratio [HR] 1.70, 95% confidence interval [CI] 1.11-2.60; p = 0.014), whereas female sex (HR 2.12, 95% CI 1.40-3.22; p < 0.001) and liver cirrhosis (HR 2.36, 95% CI 1.31-4.25; p = 0.004) were both associated with an increased risk of intrahepatic recurrence at other sites. Median survival after recurrence was better among patients who underwent repeat curative-intent surgery (48.7 months) versus other treatments (9.7 months) [p < 0.001]. CONCLUSIONS Different recurrence patterns and timing of recurrence suggest biological heterogeneity of ICC tumor recurrence. Understanding timing and risk factors associated with different types of recurrence can hopefully inform discussions around adjuvant therapy, surveillance, and treatment of recurrent disease.

Abstract
OBJECTIVE Create practice guidelines for the appropriate use of red blood cell transfusions in hepatectomy. BACKGROUND Hepatectomy is associated with a high prevalence of transfusions. A transfusion can be life-saving, but can be associated with important adverse effects. Given the prevalence, the potential for benefit and harm, and the difficulty in conducting clinical trials, transfusion in hepatectomy is well-suited for a study of appropriateness. METHODS Using the RAND/UCLA appropriateness method, an international, multidisciplinary expert panel in hepatobiliary surgery, anesthesia, transfusion medicine, and critical care rated a series of 468 perioperative scenarios for transfusion appropriateness. Scenarios were rated individually, and again during an inperson group moderated session. Median scores and level of agreement were calculated to classify each scenario as appropriate, inappropriate, or uncertain. RESULTS Approximately, 47.4% of scenarios were rated as appropriate for transfusion, 28.2% were inappropriate, and 24.4% were uncertain. The key recommendations for intraoperative transfusion were (i) it is never inappropriate to transfuse for significant bleeding or ST segment changes; (ii) it is never inappropriate to transfuse for an intraoperative hemoglobin ≤75 g/L; and (iii) in the absence of significant bleeding or ST changes, transfusion for hemoglobin of ≥95 g/L is inappropriate, and transfusion for hemoglobin of ≥85 g/L requires strong justification. The key recommendations for postoperative transfusions were: (i) in a stable, asymptomatic patient, an appropriate transfusion trigger is 70 g/L (without coronary artery disease) or 80 g/L (with coronary artery disease) and (ii) it is appropriate to transfuse any patient for a hemoglobin of ≤75 g/L either immediately post-operative, or with a significant decrease from the previous day (>15 g/L). CONCLUSIONS Based on best available evidence and expert opinion, criteria for appropriate perioperative red blood cell transfusions in hepatectomy were determined.

Abstract
BACKGROUND The association between body mass index (BMI) and long-term outcomes of patients with ICC has not been well defined. We sought to define the presentation and oncologic outcomes of patients with ICC undergoing curative-intent resection, according to their BMI category. METHODS Patients who underwent resection of ICC were identified in a multi-institutional database. Patients were categorized as normal weight (BMI 18.5-24.9 kg/m2), overweight (BMI 25.0-29.9 kg/m2) and obese (BMI≥30 kg/m2) according to the World Health Organization (WHO) definition. Impact of clinico-pathological factors on recurrence-free survival (RFS) was assessed using Cox proportional hazards model among patients in the three BMI categories. RESULTS Among a total of 790 patients undergoing curative-intent resection of ICC in the analytic cohort, 399 (50.5%) had normal weight, 274 (34.7%) were overweight and 117 (14.8%) were obese. Caucasian patients were more likely to be obese (66.7%, n = 78) and overweight (47.1%, n = 129) compared with Asian (obese: 18.8%, n = 22; overweight: 46%, n = 126) and other races (obese: 14.5%, n = 17; overweight: 6.9%, n = 19)(p < 0.001). There were no differences in the presence of cirrhosis (10.9%, vs. 12.8%, vs. 12.9%), preoperative jaundice (8.6% vs. 9.5% vs. 12.0%), or levels of CA 19-9 (75, IQR 24.6-280 vs. 50.9, IQR 17.9-232 vs. 43, IQR 16.9-192.7) among the BMI groups (all p > 0.05). On multivariable analysis, increased BMI was an independent risk factor for tumor recurrence (OR 1.16, 95% CI 1.02-1.32, for every 5 unit increase). CONCLUSION Increasing BMI was associated with incremental increases in the risk of recurrence following curative-intent resection of ICC. Future studies should aim to achieve a better understanding of BMI-related factors relative to prognosis of patients with ICC.

Portal vein embolization does not affect the long-term survival and risk of cancer recurrence among colorectal liver metastases patients: A prospective cohort study. Int J Surg 2018; 61:42-47. [PMID: 30537548 DOI: 10.1016/j.ijsu.2018.11.029] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2018] [Revised: 11/18/2018] [Accepted: 11/29/2018] [Indexed: 12/25/2022]
Abstract
BACKGROUND Previous studies comparing the survival outcomes of liver resections with and without preoperative portal vein embolization (PVE) for colorectal liver metastases (CLM) have linked PVE to higher rate of tumor progression, lower overall survival (OS) and lower disease-free survival (DFS). The lack of adjusted models to compare these outcomes is a limitation of these studies since patients requiring PVE may differ significantly from the ones receiving upfront surgery. MATERIALS AND METHODS Prospective cohort study of 128 patients undergoing CLM resection. The OS analysis followed an intent-to-treat (ITT) approach. The adjusted impact of PVE on OS and DFS was evaluated using multivariate Cox regression models. RESULTS Seventy-one patients underwent PVE before attempting a liver resection while 57 received upfront surgery (NoPVE). All NoPVE patients were resected while 14 PVE participants (19.7%) were not operated (tumor progression = 9/14). PVE patients had a significantly higher preoperative lesions count (3 [1.75-4] vs 1 [1-2.5]; p < 0.001), a higher prevalence of bilateral metastases (23.5% vs 8.8, p = 0.028) and a higher count of neo-adjuvant chemotherapy cycles compared to NoPVE patients. The OS of PVE patients was similar to NoPVE participants (44.7 months [26.9-69.5] vs 49.0 [24.9-64.8], p = 0.761). The DFS of resected PVE patients was higher than NoPVE patients (33.2 months [10.7-54.6] vs 23.4 months [14.1-58.1], p = 0.991). In the adjusted models, preoperative lesions count was the only significant predictor of overall mortality (HR+IC95 = 1.06 (1.02-1.11) p = 0.005) and cancer recurrence (HR+IC95 = 1.14 (1.03-1.27) p = 0.012). CONCLUSION In the context of CLM, patients requiring PVE differ significantly from patients receiving upfront surgery. This confirms the need for adjusted models when comparing the clinical outcomes of both groups. Our adjusted analysis suggests that PVE is not a significant predictor of a lower OS or DFS. PVE allowed the resection of 80% of participants with initially unresectable CLM. INSTITUTIONAL PROTOCOL NUMBER 12.106 STUDY REGISTRATION NUMBER: NCT03168230.

Abstract
BACKGROUND Intraductal-growth (IG) type of intrahepatic cholangiocarcinoma (ICC) may be associated with a favorable prognosis compared with mass-forming (MF) and periductal-infiltrating (PI) ICC. METHODS The clinico-pathological characteristics and long-term outcomes of 1206 patients undergoing liver resection for ICC were compared based on the ICC morphological classification. RESULTS Compared with MF patients, IG patients had a higher incidence of poor/un-differentiated tumor, lympho-vascular, and perineural invasion (poor/un-differentiated: MF, 18% vs. IG, 24%; lympho-vascular invasion: MF, 30% vs. IG, 35%; perineural invasion: MF, 17% vs. IG, 33%; all p > 0.05). The pattern of recurrence was different among MF patients (intrahepatic only: 63%; extrahepatic only: 22%; both intra- and extrahepatic: 16%) versus IG patients (intrahepatic only: 46%; extrahepatic: 25%; both intra- and extrahepatic: 29%) (p < 0.001). Moreover, while 78% of patients with MF had an early recurrence (<18 months from surgery), 59% of IG patients had and early recurrence (p = 0.039). On multivariable analysis, after controlling for competing risk factors, IG patients had a similar prognosis as MF patients (HR 0.90, p = 0.69). CONCLUSION While IG patients more frequently presented with more adverse pathological characteristics, the prognosis of IG patients was comparable with MF patients after controlling for all these adverse factors.

Abstract
Purpose We investigated the translational value of reflex testing for germline mutations in four homology-directed DNA repair predisposition genes ( BRCA1, BRCA2, PALB2, and ATM) in consecutive patients with pancreatic adenocarcinoma. Methods One hundred fifty patients with French-Canadian (FC) ancestry were evaluated for founder mutations, and 114 patients were subsequently assessed by full gene sequencing and multiplex ligation-dependent probe amplification for nonfounder mutations. Two hundred thirty-six patients unselected for ancestry were also assessed for mutations by full gene sequencing. Results The FC founder mutation prevalence among the 150 patients was 5.3% (95% CI, 2.6% to 10.3%), and the nonfounder mutation prevalence across the four genes among the 114 patients tested was 2.6% (95% CI, 0.6% to 7.8%). In the case series unselected for ancestry, 10.0% (95% CI, 2.7% to 26.4%) of patients reporting Ashkenazi Jewish (AJ) ancestry carried an AJ founder mutation, with no nonfounder mutations identified. The mutation prevalence among patients without FC/AJ ancestry was 4.9% (95% CI, 2.6% to 8.8%). Mutations were more frequent in patients diagnosed at ≤ 50 years of age ( P = .03) and in patients with either two or more first- or second-degree relatives with pancreas, breast, ovarian or prostate cancer, or one such relative and a second primary of one of these cancer types ( P < .001). BRCA1, BRCA2, and PALB2 carriers with late-stage (III or IV) disease had an overall survival advantage ( P = .049), particularly if treated with platinum-based chemotherapies ( P = .030). Conclusion Considering these results, we recommend reflex founder mutation testing of patients with FC/AJ ancestry and full gene sequencing of patients who are ≤ 50 years or meet the identified family history criteria. Reflex testing of all incident patients for these four genes may become justified as full gene sequencing costs decline.

Abstract
BACKGROUND While several prognostic models have been developed to predict long-term outcomes in resectable intrahepatic cholangiocarcinoma (ICC), their prognostic discrimination remains limited. The addition of tumor markers might improve the prognostic power of the classification schemas proposed by the AJCC 8th edition and the Liver Cancer Study Group of Japan (LCSGJ). METHODS The prognostic discrimination of the AJCC and the LCSGJ were compared before and after the addition of CA 19-9 and CEA, using Harrell's C-index, net reclassification improvement (NRI) and the integrated discrimination improvement (IDI) in an international, multi-institutional cohort. RESULTS Eight hundred and five surgically treated patients with ICC that met the inclusion criteria were identified. On multivariable analysis, CEA5 ng/mL, 100IU/mL CA 19-9< 500IU/mL and CA 19-9500 IU/mL were associated with worse overall survival. The C-index of the AJCC and the LCSGJ improved from 0.540 to 0.626 and 0.553 to 0.626, respectively following incorporation of CA 19-9 and CEA. The NRI and IDI metrics confirmed the superiority of the modified AJCC and LCSGJ, compared to the original versions. CONCLUSION The inclusion of preoperative CA 19-9 and CEA in the AJCC and LCSGJ staging schemas may improve prognostic discrimination among surgically treated patients with ICC.

Abstract
Ingested foreign bodies are a common presentation. Ingested foreign bodies can migrate/penetrate to the liver. Patients can present with symptoms including epigastric abdominal pain. In some cases hepatic foreign bodies can be extracted through a laparoscopic approach.
Introduction Less than 1% of ingested foreign bodies will require surgical management. An uncommon complication of ingested foreign body is migration to the liver. We present a case of laparoscopic removal of an intrahepatic foreign body. Presentation of case 32-year-old female presented with a four month history of epigastric abdominal pain following suspected foreign body ingestion. CT scan demonstrated a metallic object lying in the left lateral segment of the liver. The patient was brought to the operating room where the object was removed laparoscopically and was found to be a sewing needle. Discussion Hepatic foreign bodies are an uncommon entity and typically result from a transcutaneous or ingested (e.g., gastrointestinal) source. Symptoms are often vague and can develop remote from the time of ingestion. Surgical management is warranted for symptomatic intrahepatic foreign bodies. Conclusion Laparoscopy is an effective surgical method for removal of intrahepatic foreign bodies in some cases.

Abstract
BACKGROUND We sought to investigate the prognosis of patients following curative-intent surgery for intrahepatic cholangiocarcinoma (ICC) stratified by hepatitis B (HBV-ICC), hepatolithiasis (Stone-ICC), and no identifiable cause (conventional ICC) etiologic subtype. METHODS 986 patients with HBV-ICC (n = 201), stone-ICC (n = 103), and conventional ICC (n = 682) who underwent curative-intent resection were identified from a multi-institutional database. Propensity score matching (PSM) was used to mitigate residual bias. RESULTS HBV-ICC patients more often had cirrhosis, earlier stage tumors, a mass-forming lesion, well-to-moderate tumor differentiation, and an R0 resection versus stone-ICC or conventional ICC patients. Five-year recurrence-free survival among HBV-ICC and conventional ICC patients was 23.9 and 17.8%, respectively, versus a recurrence-free of only 8.3% among patients with stone-ICC. Similarly, 5-year overall survival among patients with stone-ICC was only 18.3% compared with 48.9 and 38.0% for patients with HBV-ICC and conventional ICC, respectively. On PSM, patients with stone-ICC group had equivalent long-term outcomes as HBV-ICC patients. In contrast, on PSM, stone-ICC patients had a median overall survival of only 18.0 months versus 44.0 months for patients with conventional ICC. Median overall survival after intrahepatic-only recurrence among patients who had stone-ICC (6.0 months) was worse than OS among HBV-ICC (13.0 months) or conventional ICC (12.0 months) (p = 0.006 and p = 0.082, respectively). CONCLUSIONS While HBV-ICC had a better prognosis on unadjusted analyses, these differences were mitigated on PSM suggesting no stage-for-stage differences in outcomes compared with stone-ICC or conventional ICC. In contrast, patients with stone-ICC had worse long-term outcomes. These data highlight the relative importance of ICC etiology relative to established clinicopathological factors in the prognosis of patients with ICC.

Abstract
BACKGROUND Intrahepatic cholangiocarcinoma (ICC) is an aggressive malignancy. We sought to examine the association between preoperative prognostic nutritional index (PNI) and long-term overall survival among patients with ICC who underwent curative-intent resection. METHODS Patients who underwent hepatectomy for ICC between 1990 and 2015 were identified using an international multi-institutional database. Clinic-pathological characteristics and long-term outcomes of patients with PNI ≥ 40 and <40 were compared using univariable and multivariable analyses. RESULTS Among 637 patients, 53 patients had PNI < 40 (8.3%) and 584 patients had PNI ≥ 40 (91.7%). While there was no difference between PNI groups with regard to tumor size (P = .87), patients with PNI < 40 were more likely to have multifocal disease (PNI < 40, n = 16, 30.2% vs PNI ≥ 40, n = 65, 11.1%; P < 0.001), poorly differentiated or undifferentiated ICC (PNI < 40, n = 13, 25.5% vs PNI ≥ 40, n = 75, 13.1%; P = 0.020) and T2/T3/T4 disease vs patients with PNI ≥ 40 (PNI < 40, n = 38, 71.7% vs PNI ≥ 40, n = 265, 45.4%; P < 0.001). Patients with PNI ≥ 40 had better OS vs patients with PNI < 40 (5-year OS: PNI ≥ 40: 47.5%, 95% CI, 42.2 to 52.6% vs PNI < 40: 24.6%, 95% CI, 12.1 to 39.6%; P < 0.001). On multivariable analysis, PNI < 40 remained associated with increase risk of death (HR, 1.71; 95% CI, 1.15 to 2.53; P = 0.008). CONCLUSION A low preoperative PNI was associated with a more aggressive ICC phenotype. After controlling for these factors, PNI remained independently associated with a markedly worse prognosis.
