Background: Liver transplantation in patients with unresectable early-stage (<3 cm, node negative) hilar cholangiocarcinoma has been recently reported to be associated with longer survival compared to liver resection and therefore suggested as potential treatment option also in resectable disease. Here, we investigated the outcome of resection in early-stage tumours as the standard of care in an experienced European centre., Methods: Patients with de novo resectable hilar cholangiocarcinomas who underwent liver resection between mid-2009 and December 2017 were classified as early-stage (<3 cm and node negative) or later-stage tumours (≥3 cm and/or node positive), and were investigated with respect to clinical outcome., Results: Fifty-six patients were analyzed of whom 17 had early-stage tumours and 39 had later-stage tumours. The sex ratio (m:f) was 30:26. The median age was 65 years (range 33-80). The median follow-up was 17.0 months (range 0.7-92.4). 5-year overall survival (OS) rates were 82% in patients with early-stage tumours and 23% in patients with later-stage tumours, respectively. Median OS was 89.9 months and 27.6 months, respectively (HR 0.25 (95% CI 0.08-0.84), P = 0.024)., Conclusions: In an experienced European centre, 5-year survival rates after liver resection for early-stage hilar cholangiocarcinoma are comparable with reported outcomes after transplantation. The results of this study question the value of liver transplantation in this setting, especially with respect to the shortage of transplantable organs worldwide., (Copyright © 2018 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Background: Scoring systems were developed to stratify patients with colorectal liver metastases considered for liver resection into different risk groups. Such scores have never been evaluated in recurrent liver metastases. The aim of this study was to evaluate whether these scores are applicable to patients with recurrent colorectal liver metastases and treated with curative intent., Methods: We retrospectively analyzed data from 375 consecutive patients who underwent liver surgery for colorectal liver metastases between June 2010 and August 2015. Seventy-three patients developed liver-limited recurrence treated with curative intent. The predictive value of 6 scores (Fong, Sofocleous, Nagashima, Nordlinger, Konopke, and the Basingstoke index) was assessed in this set of patients., Results: Median follow-up was 36.2 months. Overall survival and progression-free survival were 33.6 and 5.6 months, respectively. When scores were applied for OS, none showed a significant stratification between patients, although Nagashima's score showed a significant difference in overall survival between patients from the low-risk group and those from the intermediate- and high-risk groups (40.8 vs 30.5 months, P = 0.039). For PFS, only Fong's score showed a statistically significant stratification (6.6 vs 4.7 months, P = 0.027)., Conclusion: Scoring systems are of limited-value in stratifying patients operated on for recurrent colorectal liver metastases., (© 2017 Wiley Periodicals, Inc.)

Background: The prognosis of patients undergoing liver resection for colorectal liver metastases (CLM) seems to be altered when the primary tumour is right-sided. However, data are lacking and conflicting. We aimed to evaluate the influence of the primary tumour location on oncologic outcomes following such surgery., Methods: We retrospectively analysed prospectively collected data from 376 consecutive patients who underwent liver surgery for CLM between June 2010 and August 2015. We compared the outcomes of patients with right colon tumours and those with left colorectal tumours. The splenic flexure was used as the cut-off point to determine the anatomic primary site., Results: Among the 364 patients eligible, 74 (20.3%) had a right-sided primary tumour. These patients were older, had a poorer American Society of Anaesthesiologists status and had fewer node-positive primary tumours. The CLM characteristics were similar between both groups. Median PFS was not significantly different between the two groups at 9.9 months, as well as the pattern of recurrence. Median OS was shorter for patients with right-sided primary tumour (34.6 versus 45.3 months, p = 0.035). Similar results were observed when patients with rectal tumour were excluded from analysis (34.6 vs. 47.5 months, p = 0.007). Primary tumour site was an independent prognosis factor in multivariate analysis., Conclusion: Right-sided location of the primary tumour is associated with worse OS after surgery for CLM, but seems to have no influence on PFS, and on the pattern of recurrence., (Copyright © 2017 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Background: Liver-limited recurrence after resection of colorectal liver metastases is a frequent occurrence, and can in some cases be treated with curative intent. Although surgical re-resection remains standard of care, there is growing interest in the role of ablation in this setting. The aim of this study was to compare the outcomes after curative-intent ablation and resection in patients with recurrent colorectal liver metastases., Methods: We retrospectively analysed data from 366 consecutive patients who underwent liver resection for colorectal liver metastases between June 2010 and August 2015. Sixty-four developed liver-limited recurrence which was treated with curative intent, thirty-three (51.6%) by ablation and 31 (48.4%) by repeat resection., Results: Patient groups were well matched, with surgically resected patients showing higher pre-operative carcinoembryonic antigen levels and larger metastases. There were fewer post-operative complications and shorter length of stay in the ablation group (p < 0.02). After a median follow-up of 36.2 months, median overall survival was the same for both the resected and ablated groups at 33.3 months. Median progression-free survival was longer for patients treated with surgery (10.2 months) compared to ablation (4.3 months) (p = 0.002)., Conclusions: Ablation or resection for liver-limited recurrence after surgery for colorectal liver metastases is associated with improved overall survival compared with systemic chemotherapy alone, and should always be considered for patients with resectable liver recurrence. Although ablation seemed to be associated with a shorter progression-free survival, post-procedure morbidity was significantly lower. The choice between ablation and resection should therefore be made on a personalised basis., (Copyright © 2017 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Background: Posthepatectomy liver failure (PHLF) contributes significantly to morbidity and mortality after liver surgery. Standardized assessment of preoperative liver function is crucial to identify patients at risk. These European consensus guidelines provide guidance for preoperative patient assessment. Methods: A modified Delphi approach was used to achieve consensus. The expert panel consisted of hepatobiliary surgeons, radiologists, nuclear medicine specialists, and hepatologists. The guideline process was supervised by a methodologist and reviewed by a patient representative. A systematic literature search was performed in PubMed/MEDLINE, the Cochrane library, and the WHO International Clinical Trials Registry. Evidence assessment and statement development followed Scottish Intercollegiate Guidelines Network methodology. Results: Based on 271 publications covering 4 key areas, 21 statements (at least 85 per cent agreement) were produced (median level of evidence 2- to 2+). Only a few systematic reviews (2++) and one RCT (1+) were identified. Preoperative liver function assessment should be considered before complex resections, and in patients with suspected or known underlying liver disease, or chemotherapy-associated or drug-induced liver injury. Clinical assessment and blood-based scores reflecting liver function or portal hypertension (for example albumin/bilirubin, platelet count) aid in identifying risk of PHLF. Volumetry of the future liver remnant represents the foundation for assessment, and can be combined with indocyanine green clearance or LiMAx® according to local expertise and availability. Functional MRI and liver scintigraphy are alternatives, combining FLR volume and function in one examination. Conclusion: These guidelines reflect established methods to assess preoperative liver function and PHLF risk, and have uncovered evidence gaps of interest for future research. [ABSTRACT FROM AUTHOR]
