Neoadjuvant chemotherapy response influences outcomes in non-colorectal, non-neuroendocrine liver metastases.

BACKGROUND: Indications for surgical resection of non-colorectal, non-neuroendocrine (NCNNE) liver metastases are unclear. This study analysed the influence of response to neoadjuvant chemotherapy and the presence of extrahepatic disease (EHD) on outcomes. METHODS: Patients who underwent hepatic resection for NCNNE liver metastases and who received neoadjuvant chemotherapy at a single centre between 1982 and 2016 were analysed retrospectively. Patients were classified as having no EHD, controlled EHD or non-controlled EHD. RESULTS: Hepatic resection was performed in 199 patients (81·2 per cent) after partial or complete response to chemotherapy or disease stabilization, and 46 patients (18·8 per cent) after tumour progression. Patients with progressive disease after chemotherapy had worse overall survival than those without (23 versus 50·4 per cent at 5 years; P = 0·004). Median survival was 63·6 (range 31·1-94·8) months for patients without EHD, 34·8 (19·2-49·2) months for those with controlled EHD and 7·2 (1·2-13·2) months for patients with non-controlled EHD (P = 0·004). In multivariable analysis, EHD (P = 0·004), response to chemotherapy (P = 0·004) and resection margins (P = 0·002) were all independent predictors of overall survival, regardless of primary tumour site. CONCLUSION: The prognosis of patients with NCNNE liver metastases is influenced by preoperative chemotherapy and resectability.

Large hepatocellular carcinoma: Does fibrosis really impact prognosis after resection?

BACKGROUND: Hepatectomy remains the standard treatment for large hepatocellular carcinoma (LHCC) ≥5cm. Fibrosis may constitute a contraindication for resection because of high risk of post-hepatectomy liver failure, but its impact on patient outcome and cancer recurrence remains ill defined. Our aim was to compare predictors of survival in patients with and without cirrhosis following hepatectomy for LHCC. METHODS: The data on consecutive patients undergoing hepatectomy for LHCC in two tertiary centres between 2012 and 2016 were reviewed. The outcomes of cirrhotic (F4) and non-cirrhotic (F0-F3) patients were compared. Patients with perioperative medical (sorafenib) or radiological (transarterial chemoembolization, radiofrequency) treatments were excluded. RESULTS: Sixty patients were included. Preoperative and intraoperative features were identical between both groups. Cirrhotics (n=15) presented more satellite nodules on specimens (73% vs. 44%; P=0.073) but better differentiated lesions than non-cirrhotics (P=0.041). The median overall survival of cirrhotics was 34 vs. 29months for non-cirrhotics (P=0.8), and their disease-free survival was 14 versus 18 months (P=0.9). Fibrosis stage did not impact overall (P=0.2) nor disease-free survivals (P=0.6). CONCLUSION: Hepatectomy for LHCC in cirrhotics can achieve acceptable oncological results when compared to non-cirrhotic patients. Curative resection of LHCC should be attempted if liver function is acceptable, whatever the fibrosis stage.

Surgical resection versus systemic therapy for breast cancer liver metastases: Results of a European case matched comparison.

BACKGROUND: Resection of breast cancer liver metastases (BCLM) combined with systemic treatment is increasingly accepted but not offered as therapeutic option. New evidence of the additional value of surgery in these patients is scarce while prognoses without surgery remains poor. PATIENTS AND METHODS: For this case matched analysis, all nationally registered patients with BCLM confined to the liver in the Netherlands (systemic group; N = 523) were selected and compared with patients who received systemic treatment and underwent hepatectomy (resection group; N = 139) at a hepatobiliary centre in France. Matching was based on age, decade when diagnosed, interval to metastases, maximum metastases size, single or multiple tumours, chemotherapy, hormonal or targeted therapy after diagnosis. Based on published guidelines, palliative systemic treatment strategies are similar in both European countries. RESULTS: Between 1983 and 2013, 3894 patients were screened for inclusion. Overall median follow-up was 80 months (95% CI 70-90 months). The median, 3- and 5-year overall survival of the whole population was 19 months, 29% and 19%, respectively. The resection and systemic group had median survival of 73 vs. 13 months (P < 0.001), respectively. Three and 5-year survival was 18% and 10% for the systemic group and 75% and 54% for the resection group, respectively. After matching, the resection group had a median overall survival of 82 months with a 3- and 5-year overall survival of 81% and 69%, respectively, compared with a median overall survival of 31 months in the systemic group with a 3- and 5-year overall survival of 32% and 24%, respectively (HR 0.28, 95% CI 0.15-0.52; P < 0.001). CONCLUSIONS: For patients with BCLM, liver resection combined with systemic treatment results in improved overall survival compared to systemic treatment alone. Liver resection should be considered in selected cases.

Neoadjuvant chemotherapy for initially unresectable intrahepatic cholangiocarcinoma.

BACKGROUND: Locoregional extension of intrahepatic cholangiocarcinoma (ICC) at the time of diagnosis results in a low resectability rate and poor prognosis. The aim of this retrospective study was to assess the efficacy of neoadjuvant chemotherapy for locally advanced ICC. METHODS: All consecutive patients with ICC between 2000 and 2013 were included prospectively in a single-centre database and analysed retrospectively. Patients with locally advanced ICC considered as initially unresectable received primary chemotherapy, followed by surgery in those with secondary resectability. Results of patients who underwent surgery for locally advanced ICC were compared with those of patients with initially resectable ICC treated by surgery alone. RESULTS: A total of 186 patients were included in the study. Of 74 patients with locally advanced ICC, 39 (53 per cent) underwent secondary resection after a median of six chemotherapy cycles. Patients in this group were younger (P = 0·030) and had more advanced disease than those who had surgery alone, and presented more frequently with lymphadenopathy (P = 0·010) and vascular invasion (P = 0·010). Postoperative morbidity and mortality were no different between the groups. The median survival of patients who had surgery after chemotherapy was 24·1 months, and that of patients who had surgery alone was 25·7 months (P = 0·391). CONCLUSION: Patients with locally advanced ICC treated by surgery following neoadjuvant chemotherapy had similar short- and long-term results to patients with initially resectable ICC who had surgery alone. Neoadjuvant chemotherapy as a first-line treatment for locally advanced ICC may be an effective downstaging option, facilitating secondary resectability in patients with initially unresectable disease.

Outcomes of surgical shunts and transjugular intrahepatic portasystemic stent shunts for complicated portal hypertension.

BACKGROUND: Transjugular intrahepatic portasystemic stent shunt (TIPSS), instead of surgical shunt, has become the standard treatment for patients with complicated portal hypertension. This study compared outcomes in patients who underwent TIPSS or surgical shunting for complicated portal hypertension. METHODS: This was a retrospective study of all consecutive patients who received portasystemic shunts from 1994 to 2014 at a single institution. Patients who underwent surgical shunting were compared with those who had a TIPSS procedure following one-to-one propensity score matching. The primary study endpoints were overall survival and shunt failure, defined as major variceal rebleeding, relapse of refractory ascites, irreversible shunt occlusion, liver failure requiring liver transplantation, or death. RESULTS: A total of 471 patients received either a surgical shunt or TIPSS. Of these, 334 consecutive patients with cirrhosis who underwent elective surgical shunting (34) or TIPSS (300) for repeated variceal bleeding or refractory ascites were evaluated. Propensity score matching yielded 31 pairs of patients. There were no between-group differences in morbidity and 30-day mortality rates. However, shunt failure was less frequent after surgical shunting than TIPSS (6 of 31 versus 16 of 31; P = 0·016). The 5-year shunt failure-free survival (77 versus 15 per cent; P = 0·008) and overall survival (93 versus 42 per cent; P = 0·037) rates were higher for patients with surgical shunts. Multivariable analysis revealed that a Model for End-Stage Liver Disease (MELD) score exceeding14 and TIPSS were independently associated with shunt failure. In patients with MELD scores of 14 or less, the 5-year overall survival rate remained higher after surgical shunting than TIPSS (100 versus 40 per cent; P < 0·001). CONCLUSION: Surgical shunting achieved better results than TIPSS in patients with complicated portal hypertension and low MELD scores.

Long-term outcomes of radiofrequency ablation combined with hepatectomy compared with hepatectomy alone for colorectal liver metastases.

BACKGROUND: Combining radiofrequency ablation (RFA) with hepatectomy may enable treatment with curative intent for patients with colorectal liver metastasis (CRLM). However, the oncological outcomes in comparison with resection alone remain to be clarified. METHODS: Patients who underwent a first hepatectomy between 2001 and 2012 for CRLM were enrolled. Short- and long-term outcomes of patients who underwent hepatectomy plus RFA were compared with those of patients who had hepatectomy alone using propensity score matching. RESULTS: Of a total of 553 patients, hepatectomy + RFA and hepatectomy alone were performed in 37 and 516 respectively. Before matching, patients in the hepatectomy + RFA group were characterized primarily by a larger tumour burden. After matching of 31 patients who underwent hepatectomy + RFA with 93 who had hepatectomy alone, background characteristics were well balanced. In the matched cohort, overall and disease-free survival in the hepatectomy + RFA group were no different from those among patients who had hepatectomy alone (5-year overall survival rate 57 versus 61 per cent, P = 0·649; 5-year disease-free survival rate 19 versus 17 per cent, P = 0·865). Local recurrence at the ablated site was observed in four of 31 patients (13 per cent). Although overall local recurrence (ablated site and/or cut surface) was more frequent in the hepatectomy + RFA group (9 of 31 (29 per cent) versus 11 of 93 (12 per cent); P = 0·032), there was no difference in intrahepatic disease-free survival between the two groups (P = 0·705). CONCLUSION: Hepatectomy + RFA achieved outcomes comparable to hepatectomy alone. Combining RFA with hepatectomy should be considered as an option to achieve cure.

Outcome after associating liver partition and portal vein ligation for staged hepatectomy and conventional two-stage hepatectomy for colorectal liver metastases.

BACKGROUND: Although associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has been increasingly adopted by many centres, the oncological outcome for colorectal liver metastases compared with that after two-stage hepatectomy is still unknown. METHODS: Between January 2010 and June 2014, all consecutive patients who underwent either ALPPS or two-stage hepatectomy for colorectal liver metastases in a single institution were included in the study. Morbidity, mortality, disease recurrence and survival were compared. RESULTS: The two groups were comparable in terms of clinicopathological characteristics. ALPPS was completed in all 17 patients, whereas the second-stage hepatectomy could not be completed in 15 of 41 patients. Ninety-day mortality rates for ALPPS and two-stage resection were 0 per cent (0 of 17) versus 5 per cent (2 of 41) (P = 0·891). Major complication rates (Clavien grade at least III) were 41 per cent (7 of 17) and 39 per cent (16 of 41) respectively (P = 0·999). Overall survival was significantly lower after ALPPS than after two-stage hepatectomy: 2-year survival 42 versus 77 per cent respectively (P = 0·006). Recurrent disease was more often seen in the liver in the ALPPS group. Salvage surgery was less often performed after ALPPS (2 of 8 patients) than after two-stage hepatectomy (10 of 17). CONCLUSION: Although major complication and 90-day mortality rates of ALPPS were similar to those of two-stage hepatectomy, overall survival was significantly lower following ALPPS.

Drop-out between the two liver resections of two-stage hepatectomy. Patient selection or loss of chance?

BACKGROUND: Two-stage hepatectomy (TSH) is the present standard for multiple bilobar colorectal liver metastases (CLM), but 25-35% of patients fail to complete the scheduled procedure (drop-out). To elucidate if drop-out of TSH is a patient selection (as usually considered) or a loss of chance. METHODS: All the consecutive patients scheduled for a TSH at the Paul Brousse Hospital between 2000 and 2012 were considered. TSH patients were matched 1:1 with patients receiving a one-stage ultrasound-guided hepatectomy (OSH) at the Humanitas Research Hospital in the same period. Matching criteria were: primary tumor N status; timing of CLM diagnosis; CLM number and distribution into the liver. RESULTS: Sixty-three pairs of patients were analyzed. Demographic and tumor characteristics were similar (median 7 CLM), except for more chemotherapy lines and adjuvant chemotherapy in TSH. Drop-out rate of TSH was 38.1% (0% of OSH). The two groups had similar R0 resection rate (19.0% OSH vs. 15.9% TSH). OSH and completed TSH had similar five-year survival (from CLM diagnosis 49.8% vs. 49.7%, from liver resection 36.1% vs. 44.3%), superior to drop-out (10% three-year survival, p < 0.001). OSH and completed TSH had similar recurrence-free survival (at three years 21.7% vs. 20.5%) and recurrence sites. The completion of resection (drop-out vs. OSH/completed TSH) was the only independent prognostic factor (p = 0.003). CONCLUSIONS: Drop-out of TSH could be a loss of chance rather than a criteria for patient selection. "Unselected" OSH patients had the same outcomes of selected patients who completed TSH. A complete resection is the main determinant of prognosis.

Nomogram for prediction of prognosis in patients with initially unresectable colorectal liver metastases.

BACKGROUND: Although recent advances in surgery and chemotherapy have increasingly enabled hepatectomy in patients with initially unresectable colorectal liver metastases (CRLM), not all such patients benefit from surgery. The aim of this study was to develop a nomogram to predict survival after hepatectomy for initially unresectable CRLM. METHODS: Patients with initially unresectable CRLM treated with chemotherapy followed by hepatectomy between 1990 and 2012 were included in the study. A nomogram to predict survival was developed based on a multivariable Cox model. The predictive performance of the model was assessed according to the C-statistic, Kaplan-Meier curve and calibration plots. RESULTS: Of a total of 439 patients, liver and globally completed surgery was achieved in 380 (86·6 per cent) and 335 (76·3 per cent) patients respectively. The 5-year overall and disease-free survival rates were 39·9 and 10·0 per cent respectively. Based on the Cox model, the following five factors were selected for the nomogram and assigned specific scores: node-positive primary, 5; more than six metastases at hepatectomy, 7; carbohydrate antigen 19-9 level at hepatectomy above 37 units/ml, 10; disease progression during first-line chemotherapy, 9; and presence of extrahepatic disease, 4. The model achieved relatively good discrimination and calibration, with a C-statistic of 0·66. The overall survival rate for patients with a score greater than 16 was significantly worse than that for patients with a score of 16 or less (5-year survival rate 4 versus 46·3 per cent respectively; P < 0·001). CONCLUSION: The nomogram facilitates personalized assessment of prognosis for patients with initially unresectable CRLM treated with chemotherapy and with planned resection.

Conversion to resection of liver metastases from colorectal cancer with hepatic artery infusion of combined chemotherapy and systemic cetuximab in multicenter trial OPTILIV.

BACKGROUND: Systemic chemotherapy typically converts previously unresectable liver metastases (LM) from colorectal cancer to curative intent resection in ∼15% of patients. This European multicenter phase II trial tested whether hepatic artery infusion (HAI) with triplet chemotherapy and systemic cetuximab could increase this rate to 30% in previously treated patients. PATIENTS AND METHODS: Participants had unresectable LM from wt KRAS colorectal cancer. Main non-inclusion criteria were advanced extra hepatic disease, prior HAI and grade 3 neuropathy. Irinotecan (180 mg/m(2)), oxaliplatin (85 mg/m(2)) and 5-fluorouracil (2800 mg/m(2)) were delivered via an implanted HAI access port and combined with i.v. cetuximab (500 mg/m(2)) every 14 days. Multidisciplinary decisions to resect LM were taken after every three courses. The rate of macroscopic complete resections (R0 + R1) of LM, progression-free survival (PFS) and overall survival (OS) were computed according to intent to treat. RESULTS: The patient population consisted of 42 men and 22 women, aged 33-76 years, with a median of 10 LM involving a median of six segments. Up to 3 extrahepatic lesions of <1 cm were found in 41% of the patients. A median of six courses was delivered. The primary end point was met, with R0-R1 hepatectomy for 19 of the 64 previously treated patients, 29.7% (95% confidence interval 18.5-40.9). Grade 3-4 neutropenia (42.6%), abdominal pain (26.2%), fatigue (18%) and diarrhea (16.4%) were frequent. Objective response rate was 40.6% (28.6-52.3). Median PFS and OS reached 9.3 (7.8-10.9) and 25.5 months (18.8-32.1) respectively. Those with R0-R1 hepatectomy had a median OS of 35.2 months (32.6-37.8), with 37.4% (23.6-51.2) alive at 4 years. CONCLUSION: The coordination of liver-specific intensive chemotherapy and surgery had a high curative intent potential that deserves upfront randomized testing.

Ad Integrum Functional and Volumetric Recovery in Right Lobe Living Donors: Is It Really Complete 1 Year After Donor Hepatectomy?

The partial liver's ability to regenerate both as a graft and remnant justifies right lobe (RL) living donor liver transplantation. We studied (using biochemical and radiological parameters) the rate, extent of, and predictors of functional and volumetric recovery of the remnant left liver (RLL) during the first year in 91 consecutive RL donors. Recovery of normal liver function (prothrombin time [PT] ≥70% of normal and total bilirubin [TB] ≤20 µmol/L), liver volumetric recovery, and percentage RLL growth were analyzed. Normal liver function was regained by postoperative day's 7, 30, and 365 in 52%, 86%, and 96% donors, respectively. Similarly, mean liver volumetric recovery was 64%, 71%, and 85%; whereas the percentage liver growth was 85%, 105%, and 146%, respectively. Preoperative PT value (p = 0.01), RLL/total liver volume (TLV) ratio (p = 0.03), middle hepatic vein harvesting (p = 0.02), and postoperative peak TB (p < 0.01) were predictors of early functional recovery, whereas donor age (p = 0.03), RLL/TLV ratio (p = 0.004), and TLV/ body weight ratio (p = 0.02) predicted early volumetric recuperation. One-year post-RL donor hepatectomy, though functional recovery occurs in almost all (96%), donors had incomplete restoration (85%) of preoperative total liver volume. Modifiable predictors of regeneration could help in better and safer donor selection, while continuing to ensure successful recipient outcomes.

Compared efficacy of preservation solutions in liver transplantation: a long-term graft outcome study from the European Liver Transplant Registry.

Between 2003 and 2012, 42 869 first liver transplantations performed in Europe with the use of either University of Wisconsin solution (UW; N = 24 562), histidine-tryptophan-ketoglutarate(HTK; N = 8696), Celsior solution (CE; N = 7756) or Institute Georges Lopez preservation solution (IGL-1; N = 1855) preserved grafts. Alternative solutions to the UW were increasingly used during the last decade. Overall, 3-year graft survival was higher with UW, IGL-1 and CE (75%, 75% and 73%, respectively), compared to the HTK (69%) (p < 0.0001). The same trend was observed with a total ischemia time (TIT) >12 h or grafts used for patients with cancer (p < 0.0001). For partial grafts, 3-year graft survival was 89% for IGL-1, 67% for UW, 68% for CE and 64% for HTK (p = 0.009). Multivariate analysis identified HTK as an independent factor of graft loss, with recipient HIV (+), donor age ≥65 years, recipient HCV (+), main disease acute hepatic failure, use of a partial liver graft, recipient age ≥60 years, no identical ABO compatibility, recipient hepatitis B surface antigen (-), TIT ≥ 12 h, male recipient and main disease other than cirrhosis. HTK appears to be an independent risk factor of graft loss. Both UW and IGL-1, and CE to a lesser extent, provides similar results for full size grafts. For partial deceased donor liver grafts, IGL-1 tends to offer the best graft outcome.

Systematic computer tomographic scans 7 days after liver transplantation surgery can lower rates of repeat-transplantation due to arterial complications.

Arterial complications are a major cause of graft lost after liver transplantation (LT). The aim of our study was to assess the clinical impact of systematic early postoperative injected computed tomographic (CT) scans after LT rather than its performance on demand in the event of abnormalities. Two series of consecutive transplantation patients in different periods (1997-1999, 231 patients versus 2008-2010, 250 patients) were analyzed. During the first period, an injected CT scan was only performed in the event of clinical, biological, or ultrasound abnormalities revealed by tests performed daily during the first week after surgery. During the second period, in addition to standard follow-up examination, an injected CT scan was performed systematically at approximately postoperative day 7. During the first (versus the more recent) period, both recipients (whose ages were 46 ± 13 years versus 50 ± 12 years; P = .004) and donors (whose ages were 42 ± 17 versus 52 ± 17 years; P = .0001) were younger and end-stage liver disease was more common (34% versus 12%; P = .0001), but hepatocellular carcinoma (7% vs 26%; P = .0001) and retransplantation (2% versus 7%; P = .01) were less frequent. Postoperative mortality was higher during the first period (14% versus 4%; P = .0003). The incidence of early arterial thrombosis (<1 month) was similar (1.3% versus 1.6%; P = .78), but that of arterial stenosis was higher with a systematic CT scan (1.7 versus 4.4; P = .07). As a consequence of the early detection and treatment of arterial abnormalities, the repeat LT rate due to late arterial thrombosis was nil in the second period and 2.1% (5/231) in the first period. In conclusion, a systematic CT angiogram at the end of the first postoperative week reduced retransplantation rates due to late hepatic artery thrombosis by detecting patients at risk who required specific treatment.

Vascular reconstruction combined with liver resection for malignant tumours.

BACKGROUND: The resectability criteria for malignant liver tumours have expanded during the past two decades. The use of vascular reconstruction after hepatectomy has been integral in this process. However, the majority of reports are anecdotal. This is a retrospective analysis of the techniques, morbidity, mortality and risk factors of liver resections with vascular reconstruction based on a large series from a single centre. METHODS: Patients who underwent hepatic resection combined with vascular resection and reconstruction between 1997 and 2009 were included in this study. Indications for surgery, morbidity and 90-day mortality are reported along with factors predictive of operative mortality. RESULTS: Eighty-four patients had liver resection with 97 vascular resections and reconstruction. There were 44 men and 40 women with a mean(s.d.) age of 56·9(12·1) years. Mean(s.d.) follow-up was 37·3(34·1) months. All patients had primary or metastatic liver tumours. The perioperative morbidity rate was 62 per cent (52 patients) and the operative mortality rate 14 per cent (12). Predictors of operative mortality were: bilirubin level exceeding 34 µmol/ml (P = 0·023), indocyanine green retention rate at 15 min over 10 per cent (P = 0·031), duration of ischaemia (P = 0·011), amount of blood transfused (P = 0·025) and combined major extrahepatic procedure (P = 0·042). Actuarial 3- and 5-year survival rates were 44 and 26 per cent respectively. CONCLUSION: Liver resection with combined vascular resection and reconstruction can be performed in selected patients with acceptable morbidity and mortality. The lack of therapeutic alternatives and the poor outcome of non-operative management seem to justify this approach. The identification of risk factors should help improve patient selection and postoperative outcome as well as facilitate objective risk communication with surgical candidates.

Is unexpected peritoneal carcinomatosis still a contraindication for resection of colorectal liver metastases? Combined resection of colorectal liver metastases with peritoneal deposits discovered intra-operatively.

AIMS: The discovery of unexpected peritoneal carcinomatosis (PC) at the time of hepatectomy for colorectal liver metastases (CLM) is usually considered a contraindication for continuing resection. The first aim of this study was to assess the long-term outcome of patients operated for CLM, and who presented unexpected PC during laparotomy. The second aim was to identify preoperative predictors of PC. METHODS: All patients at a single center between 1985 and 2010 who had unexpected PC, discovered during planed resection of CLM, and negative preoperative imaging for PC were selected. Clinicopathological data were retrospectively analyzed to assess survival outcomes and to identify predictors of unexpected PC. RESULTS: Out of the 1340 operated patients for CLM, 42 (3%) had unexpected PC. Only patients (n = 30; 71%) who had PC limited to two abdominal regions (Median peritoneal cancer index (PCI): 2 (1-6)) were resected. Twelve patients were not resected due to the extent of peritoneal disease. The overall survival of the 30 patients resected for CLM who had limited PC was 18% at 5 years (median: 42 months). On multivariate analysis, a previous history of PC, a pT4 stage and bilobar CLM were independent predictors of unexpected PC. CONCLUSION: Unexpected PC should not be a contraindication for resection provided that the PCI is low and complete resection of all peritoneal and hepatic lesions can be achieved. Previous history of PC, a pT4 primary tumor and bilobar CLM are associated with increased risk of unexpected PC.

Repeat hepatectomy for recurrent colorectal metastases.

BACKGROUND: The oncological benefit of repeat hepatectomy for patients with recurrent colorectal metastases is not yet proven. This study assessed the value of repeat hepatectomy for these patients within current multidisciplinary treatment. METHODS: Consecutive patients treated by repeat hepatectomy for colorectal metastases between January 1990 and January 2010 were included. Patients undergoing two-stage hepatectomy were excluded. Postoperative outcome was analysed and compared with that of patients who had only a single hepatectomy. RESULTS: A total of 1036 patients underwent 1454 hepatectomies for colorectal metastases. Of these, 288 patients had 362 repeat hepatectomies for recurrent metastases. Some 225 patients (78·1 per cent) had two hepatectomies, 52 (18·1 per cent) had three hepatectomies, and 11 patients (3·8 per cent) had a fourth hepatectomy. Postoperative morbidity following repeat hepatectomy was similar to that after initial liver resection (27·1 per cent after first, 34·4 per cent after second and 33·3 per cent after third hepatectomy) (P = 0·069). The postoperative mortality rate was 3·1 per cent after repeat hepatectomy versus 1·6 per cent after first hepatectomy. Three- and 5-year overall survival rates following first hepatectomy in patients who underwent repeat hepatectomy were 76 and 54 per cent respectively, compared with 58 and 45 per cent in patients who had only one hepatectomy (P = 0·003). In multivariable analysis, repeat hepatectomy performed between 2000 and 2010 was the sole independent factor associated with longer overall survival. CONCLUSION: Repeat hepatectomy for recurrent colorectal metastases offers long-term survival in selected patients.

Fibrosing cholestatic hepatitis in HIV/HCV co-infected transplant patients-usefulness of early markers after liver transplantation.

We characterized fibrosing cholestatic hepatitis (FCH) in a large cohort of HIV/HCV co-infected patients. Between 1999 and 2008, 59 HIV infected patients were transplanted for end-stage liver disease due to HCV. Eleven patients (19%) developed FCH within a mean period of 7 months [2-27] after liver transplantation (LT). At Week 1 post-LT, the mean HCV viral load was higher in the FCH group: 6.13 log(10) IU/mL ± 1.30 versus 4.9 log(10) IU/mL ± 1.78 in the non-FCH group, p = 0.05. At the onset of acute hepatitis after LT, activity was moderate to severe in 8/11 HIV+/HCV+ patients with FCH (73%) versus 13/28 (46%) HIV+/HCV+ non-FCH (p = 0.007) patients. A complete virological response to anti-HCV therapy was observed in 2/11 (18%) patients. Survival differed significantly between the two groups (at 3 years, 67% in non-FCH patients versus 15% in FCH patients, p = 0.004). An early diagnosis of FCH may be suggested by the presence of marked disease activity when acute hepatitis is diagnosed and when a high viral load is present. The initiation of anti-HCV therapy should be considered at this point.

Operative risks of domino liver transplantation for the familial amyloid polyneuropathy liver donor and recipient: a double analysis.

Although domino liver transplantation (LT) is an established procedure, data about the operative risks are limited. This study aimed at evaluating the operative risks of domino LT. Two retrospective analyses were conducted (comparison of familial amyloid polyneuropathy [FAP] liver donors [61 patients] vs. FAP nondonors [39 patients] and FAP liver recipients [61 patients] vs. deceased donor liver recipients [61 patients]). First analysis showed a 60-day mortality of 6.6% for FAP donors and 7.7% for FAP nondonors (p = 1.0). No patient developed primary graft nonfunction. Acute rejection was higher in FAP nondonors compared to FAP donors (38.5% vs. 13.1%). Both groups had similar vascular and biliary complication rates. ICU stay was similar, whereas total hospitalization was longer for FAP nondonors. Both groups had similar 1- and 5-year patient and graft survival rates (83.4% vs. 87.2%, and 79.8% vs. 71.8%, p = 0.7) and (83.3% vs. 87.2%, and 79.1% vs.71.8%, p = 0.7). The second analysis showed a 1.6% mortality for FAP liver recipients vs. 3.2% of the control group (p = 1). Both groups had similar morbidity and technical complication rates (18.0% vs. 13.1%, p = 0.45) and (0.18 vs. 0.15, p = 0.65). The domino procedure does not add any risk to FAP donor or recipient. It increases the organ pool allowing transplantation of marginal recipients who otherwise are denied deceased donor liver transplantation.
