RESUMO

BACKGROUND: Repeat open hepatectomy (ROH) for recurrent liver tumors is the preferred approach especially after initial open hepatectomy (OH). The aim of this study is to assess feasibility and safety of repeat laparoscopic hepatectomy (RLH) after initial OH in 2 high volume hepato-biliary hospitals. METHODS: Patients were retrieved from prospective data bases from 2012 to 2020. The patients were divided into two groups according to the approach used for repeat hepatectomy, ROH and RLH groups. RESULTS: Sixty-seven patients matched the criteria, 20 in RLH and 47 in ROH. Diagnoses were hepatocellular carcinoma in 52.3%, intrahepatic cholangiocarcinoma in 7.7% and colorectal liver metastases in 40%. Median operative time and blood loss were lower in RLH (199 vs 260 min, and 100 vs 400 ml respectively), as well as overall postoperative complications (20% vs 49%). There were 2 conversions (10%) due to adhesions and one died of postoperative pancreatitis in RLH. Median hospital stay was lower in RLH (5 vs 9 days). CONCLUSION: RLH is a feasible, safe technique and a realistic option to be considered in selected patients after previous OH. Early conversion should be considered when adhesions are more severe than expected.

RESUMO

OBJECTIVE: To analyse outcomes after adult right ex-situ split graft liver transplantations (RSLT) and compare with available outcome benchmarks from whole liver transplantation (WLT). SUMMARY BACKGROUND DATA: Ex-situ SLT may be a valuable strategy to tackle the increasing graft shortage. Recently established outcome benchmarks in WLT offer a novel reference to perform a comprehensive analysis of results after ex-situ RSLT. METHODS: This retrospective multicenter cohort study analyzes all consecutive adult SLT performed using right ex-situ split grafts from 01.01.2014 to 01.06.2022. Study endpoints included 1 year graft and recipient survival, overall morbidity expressed by the comprehensive complication index (CCI©) and specific post-LT complications. Results were compared to the published benchmark outcomes in low-risk adult WLT scenarii. RESULTS: In 224 adult right ex-situ SLT, 1y recipient and graft survival rates were 96% and 91.5%, within the WLT benchmarks. The 1y overall morbidity was also within the WLT benchmark (41.8 CCI points vs. <42.1). Detailed analysis, revealed cut surface bile leaks (17%, 65.8% Grade IIIa) as a specific complication without a negative impact on graft survival. There was a higher rate of early hepatic artery thrombosis (HAT) after SLT, above the WLT benchmark (4.9% vs. ≤4.1%), with a significant impact on early graft but not patient survival. CONCLUSION: In this multicentric study of right ex-situ split graft LT, we report 1-year overall morbidity and mortality rates within the published benchmarks for low-risk WLT. Cut surface bile leaks and early HAT are specific complications of SLT and should be acknowledged when expanding the use of ex-situ SLT.

RESUMO

BACKGROUND: Despite the ongoing trend of increasing donor ages in liver transplantation (LT) setting, a notable gap persists in the availability of comprehensive guidelines for the utilization of organs from elderly donors. This study aimed to evaluate the viability of livers grafts from donors aged ≥85 years and report the post-LT outcomes compared with those from "ideal" donors under 40 years old. METHODS: Conducted retrospectively at a single center from 2005 to 2023, this study compared outcomes of LTs from donors aged ≥85 y/o and ≤40 y/o, with the propensity score matching to the recipient's gender, age, BMI, MELD score, redo-LT, LT indication, and cause of donor death. RESULTS: A total of 76 patients received grafts from donors ≥85 y/o and were compared to 349 liver grafts from donors ≤40 y/o. Prior to PSM, the 5-year overall survival was 63% for the elderly group and 77% for the young group (p = 0.002). After PSM, the 5-year overall survival was 63% and 73% (p = 0.1). A nomogram, developed at the time of graft acceptance and including HCC features, predicted 10-year survival after LT using a graft from a donor aged ≥85. CONCLUSIONS: In the context of organ scarcity, elderly donors emerge as a partial solution. Nonetheless, without proper selection, LT using very elderly donors yields inferior long-term outcomes compared to transplantation from very young donors ≤40 y/o. The resulting nomogram based on pre-transplant criteria allows for the optimization of elderly donor/recipient matching to achieve satisfactory long-term results, in addition to traditional matching methods.

RESUMO

Iron catalyses the oxidation of lipids in biological membranes and promotes a form of cell death referred to as ferroptosis1-3. Identifying where this chemistry takes place in the cell can inform the design of drugs capable of inducing or inhibiting ferroptosis in various disease-relevant settings. Whereas genetic approaches have revealed underlying mechanisms of lipid peroxide detoxification1,4,5, small molecules can provide unparalleled spatiotemporal control of the chemistry at work6. Here, we show that the ferroptosis inhibitor liproxstatin-1 (Lip-1) exerts a protective activity by inactivating iron in lysosomes. Based on this, we designed the bifunctional compound fentomycin that targets phospholipids at the plasma membrane and activates iron in lysosomes upon endocytosis, promoting oxidative degradation of phospholipids and ferroptosis. Fentomycin effectively kills primary sarcoma and pancreatic ductal adenocarcinoma cells. It acts as a lipolysis-targeting chimera (LIPTAC), preferentially targeting iron-rich CD44high cell-subpopulations7,8 associated with the metastatic disease and drug resistance9,10. Furthermore, we demonstrate that fentomycin also depletes CD44high cells in vivo and reduces intranodal tumour growth in an immunocompetent murine model of breast cancer metastasis. These data demonstrate that lysosomal iron triggers ferroptosis and that lysosomal iron redox chemistry can be exploited for therapeutic benefits.

RESUMO

AIM: To study the incidence, risk factors and management of portal vein thrombosis (PVT) after hepatectomy for perihilar cholangiocarcinoma (PHCC). PATIENTS AND METHOD: Single-center retrospective analysis of 86 consecutive patients who underwent major hepatectomy for PHCC, between 2012 and 2019, with comparison of the characteristics of the groups with (PVT+) and without (PVT-) postoperative portal vein thrombosis. RESULTS: Seven patients (8%) presented with PVT diagnosed during the first postoperative week. Preoperative portal embolization had been performed in 71% of patients in the PVT+ group versus 34% in the PVT- group (P=0.1). Portal reconstruction was performed in 100% and 38% of PVT+ and PVT- patients, respectively (P=0.002). In view of the gravity of the clinical and/or biochemical picture, five (71%) patients underwent urgent re-operation with portal thrombectomy, one of whom died early (hemorrhagic shock after surgical treatment of PVT). Two patients had exclusively medical treatment. Complete recanalization of the portal vein was achieved in the short and medium term in the six survivors. After a mean follow-up of 21 months, there was no statistically significant difference in overall survival between the two groups. FINDINGS: Post-hepatectomy PVT for PHCC is a not-infrequent and potentially lethal event. Rapid management, adapted to the extension of the thrombus and the severity of the thrombosis (hepatic function, signs of portal hypertension) makes it possible to limit the impact on postoperative mortality. We did not identify any modifiable risk factor. However, when it is oncologically and anatomically feasible, left±extended hepatectomy (without portal embolization) may be less risky than extended right hepatectomy, and portal vein resection should only be performed if there is strong suspicion of tumor invasion.

RESUMO

BACKGROUND: The European registry for minimally invasive pancreatic surgery (E-MIPS) collects data on laparoscopic and robotic MIPS in low- and high-volume centers across Europe. METHODS: Analysis of the first year (2019) of the E-MIPS registry, including minimally invasive distal pancreatectomy (MIDP) and minimally invasive pancreatoduodenectomy (MIPD). Primary outcome was 90-day mortality. RESULTS: Overall, 959 patients from 54 centers in 15 countries were included, 558 patients underwent MIDP and 401 patients MIPD. Median volume of MIDP was 10 (7-20) and 9 (2-20) for MIPD. Median use of MIDP was 56.0% (IQR 39.0-77.3%) and median use of MIPD 27.7% (IQR 9.7-45.3%). MIDP was mostly performed laparoscopic (401/558, 71.9%) and MIPD mostly robotic (234/401, 58.3%). MIPD was performed in 50/54 (89.3%) centers, of which 15/50 (30.0%) performed ≥20 MIPD annually. This was 30/54 (55.6%) centers and 13/30 (43%) centers for MIPD respectively. Conversion rate was 10.9% for MIDP and 8.4% for MIPD. Overall 90 day mortality was 1.1% (n = 6) for MIDP and 3.7% (n = 15) for MIPD. CONCLUSION: Within the E-MIPS registry, MIDP is performed in about half of all patients, mostly using laparoscopy. MIPD is performed in about a quarter of patients, slightly more often using the robotic approach. A minority of centers met the Miami guideline volume criteria for MIPD.

RESUMO

BACKGROUND: The role of positron emission tomography/computed tomography (PET/CT) in hepatocellular carcinoma (HCC) management is not clearly defined. Our objective was to analyze the utility of dual-PET/CT (18F-FDG + 18F-Choline) imaging findings on the BCLC staging and treatment decision for HCC patients. METHODS: Between January 2011 and April 2019, 168 consecutive HCC patients with available baseline dual-PET/CT imaging data were retrospectively analyzed. To identify potential refinement criteria for surgically-treated patients, survival Kaplan-Meier curves of various standard-of-care and dual-PET/CT baseline parameters were estimated. Finally, multivariate cox proportional hazard ratios of the most relevant clinico-biological and/or PET parameters were estimated. RESULTS: Dual-PET/CT findings increased the score of BCLC staging in 21 (12.5%) cases. In 24.4% (N.=41) of patients, the treatment strategy was modified by the PET findings. Combining AFP levels at a threshold of 10 ng/mL with 18F-FDG or 18F-Choline N status significantly impacted DFS (P<0.05). In particular, the combined criteria of the N+ status assessed by 18F-Choline with AFP threshold of 10 ng/mL provided a highly predictive composite parameter for estimation of DFS according to multivariate analysis (HR=10.6, P<0.05). CONCLUSIONS: The 18F-Choline / AFP composite parameter appears promising, and further prospective studies are mandatory to validate its oncological impact.

RESUMO

Background: to date, long-term outcomes of R1 vascular (R1vasc) and R1 parenchymal (R1par) resections in the setting of intrahepatic cholangiocarcinoma (iCCA) have been examined in only one study which did not find significant difference. Patients and Methods: we analyzed consecutive patients who underwent iCCA resection between 2000 and 2019 in two tertiary French medical centers. We report overall survival (OS) and disease-free-survival (DFS). Univariate and multivariate analyses were performed to determine associated factors. Results: 195 patients were analyzed. The number of R0, R1par and R1vasc patients was 128 (65.7%), 57 (29.2%) and 10 (5.1%), respectively. The 1- and 2-year OS rates in the R0, R1par and R1vasc groups were 83%, 87%, 57% and 69%, 75%, 45%, respectively (p = 0.30). The 1- and 2-year DFS rates in the R0, R1par and R1vasc groups were 58%, 50%, 30% and 43%, 28%, 10%, respectively (p = 0.019). Resection classification (HR 1.56; p = 0.003) was one of the independent predictors of DFS in multivariate analysis. Conclusions: the survival outcomes after R1par resection are intermediate to those after R0 or R1vasc resection. R1vasc resection should be avoided in patients with iCCA as it does not provide satisfactory oncological outcomes.

RESUMO

BACKGROUND: Liver resection is a curative treatment for hepatocellular carcinoma (HCC) and an alternative to liver transplantation (LT). However, post-liver resection recurrence rates remain high. This study aimed to determine whether liver stiffness measurement (LSM) correlated with recurrence and to propose a method for predicting HCC recurrence exclusively using pre-liver resection criteria. METHODS: This retrospective monocentric study included patients who had undergone LR liver resection for HCC between 2015 and 2018 and who had (1) preoperative alpha-fetoprotein scores indicating initial transplant viability and (2) available preoperative LSM data. We developed a predictive score for recurrence over time using Cox univariate regression and multivariate analysis with a combination plot before selecting the optimal thresholds (receiver operating characteristic curves + Youden test). RESULTS: Sixty-six patients were included. After an average follow-up of 40 months, the recurrence rate was 45% (n = 30). Three-year overall survival was 88%. Four preoperative variables significantly impacted the time to recurrence: age ≥70 years, LSM ≥11 kPa, international normalized ratio (INR) ≥1.2, and maximum HCC diameter ≥3 cm. By assigning 1 point per positive item, patients with a score <2 (n = 22) demonstrated greater mean overall survival (69.7 vs 54.8 months, P = .02) and disease-free survival (52.2 vs 34.7 months, P = .02) than those with a score ≥2. Patients experiencing early recurrence (<1 year) presented a significantly higher preoperative LSM (P = .06). CONCLUSION: We identified a simple preoperative score predictive of early hepatocellular carcinoma recurrence after liver resection, highlighting the role of liver stiffness. This score could help physicians select patients and make decisions concerning perioperative medical treatment.

RESUMO

In situ normothermic regional perfusion (NRP) and ex situ normothermic machine perfusion (NMP) aim to improve the outcomes of liver transplantation (LT) using controlled donation after circulatory death (cDCD). NRP and NMP have not yet been compared directly. In this international observational study, outcomes of LT performed between 2015 and 2019 for organs procured from cDCD donors subjected to NRP or NMP commenced at the donor center were compared using propensity score matching (PSM). Of the 224 cDCD donations in the NRP cohort that proceeded to asystole, 193 livers were procured, resulting in 157 transplants. In the NMP cohort, perfusion was commenced in all 40 cases and resulted in 34 transplants (use rates: 70% vs. 85% [p = 0.052], respectively). After PSM, 34 NMP liver recipients were matched with 68 NRP liver recipients. The two cohorts were similar for donor functional warm ischemia time (21 min after NRP vs. 20 min after NMP; p = 0.17), UK-Donation After Circulatory Death risk score (5 vs. 5 points; p = 0.38), and laboratory Model for End-Stage Liver Disease scores (12 vs. 12 points; p = 0.83). The incidence of nonanastomotic biliary strictures (1.5% vs. 2.9%; p > 0.99), early allograft dysfunction (20.6% vs. 8.8%; p = 0.13), and 30-day graft loss (4.4% vs. 8.8%; p = 0.40) were similar, although peak posttransplant aspartate aminotransferase levels were higher in the NRP cohort (872 vs. 344 IU/L; p < 0.001). NRP livers were more frequently allocated to recipients suffering from hepatocellular carcinoma (HCC; 60.3% vs. 20.6%; p < 0.001). HCC-censored 2-year graft and patient survival rates were 91.5% versus 88.2% (p = 0.52) and 97.9% versus 94.1% (p = 0.25) after NRP and NMP, respectively. Both perfusion techniques achieved similar outcomes and appeared to match benchmarks expected for donation after brain death livers. This study may inform the design of a definitive trial.

RESUMO

BACKGROUND: Immediate portal reperfusion is mandatory following hepatectomy combined with portal vein (PV) resection. This retrospective study analyzes the feasibility and the outcomes of the Rex shunt (RS) for reconstruction of the left portal vein (LPV) and reperfusion of the remnant left liver or lobe following hepatectomy for cancer combined with resection of the PV in adult patients. METHODS: From 2018 to 2021, an RS was used in the above setting to achieve R0 resection or when the standard LPV reconstruction failed or was deemed technically impossible. RESULTS: There were 6 male and 5 female patients (median age, 58 years) with perihilar cancer (5 cases) or miscellaneous cancers invading the PV (6 cases). A major hepatectomy was performed in 10/11 patients. The RS was indicated to achieve R0 resection or for technical reasons in 8 and 3 cases, respectively, and was feasible in all consecutive attempts with (10 cases) or without an interposed synthetic graft (1 case). Two fatal complications (PV thrombosis and pulmonary embolism) and three non-severe complications occurred in four patients within 90 days of surgery. Two patients died of tumor recurrence with a patent RS at 13 and 29 months, and 7 were recurrence free with a patent shunt with a follow-up of 1 to 37 months (median, 15 months). CONCLUSION: In case of remnant left liver or lobe following hepatectomy combined with resection of the PV, the RS may help to achieve R0 resection and is a valuable option to perform technically satisfying portal reperfusion of the remnant left liver or lobe.

RESUMO

OBJECTIVE: Evaluating the perioperative outcomes of minimally invasive (MIV) donor hepatectomy for adult live donor liver transplants in a large multi-institutional series from both Eastern and Western centers. BACKGROUND: Laparoscopic liver resection has become standard practice for minor resections in selected patients in whom it provides reduced postoperative morbidity and faster rehabilitation. Laparoscopic approaches in living donor hepatectomy for transplantation, however, remain controversial because of safety concerns. Following the recommendation of the Jury of the Morioka consensus conference to address this, a retrospective study was designed to assess the early postoperative outcomes after laparoscopic donor hepatectomy. The collective experience of 10 mature transplant teams from Eastern and Western countries was reviewed. METHODS: All centers provided data from prospectively maintained databases. Only left and right hepatectomies performed using a MIV technique were included in this study. Primary outcome was the occurrence of complications using the Clavien-Dindo graded classification and the Comprehensive Complication Index during the first 3 months. Logistic regression analysis was used to identify risk factors for complications. RESULTS: In all, 412 MIV donor hepatectomies were recorded including 164 left and 248 right hepatectomies. Surgical technique was either pure laparoscopy in 175 cases or hybrid approach in 237. Conversion into standard laparotomy was necessary in 17 donors (4.1%). None of the donors died. Also, 108 experienced 121 complications including 9.4% of severe (Clavien-Dindo 3-4) complications. Median Comprehensive Complication Index was 5.2. CONCLUSIONS: This study shows favorable early postoperative outcomes in more than 400 MIV donor hepatectomy from 10 experienced centers. These results are comparable to those of benchmarking series of open standard donor hepatectomy.

RESUMO

BACKGROUND: Obesity is associated with increased oncological risk and outcomes but the evidence surrounding the effect of body mass index (BMI) on increased risk of hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT) is still questionable. The purpose of this retrospective study of a large cohort of adult patients transplanted for HCC was to investigate the effect of BMI on the incidence of HCC recurrence and outcome. METHODS: Data from 427 adult recipients transplanted for HCC between 2000 and 2017 were collected. Patients were classified at time of LT according to the World Health Organization BMI classification into 3 groups; group 1: BMI <25 (n=166), group 2: BMI 25-29.9 (n=150) and group 3: BMI ≥30 (n=111). RESULTS: There were no significant changes of mean BMI overtime 26.8±5.0 kg/m2 at time of LT and 28.8±23.1 at 5 years. The recurrence rates of HCC after LT in the three groups were 19%, 16% and 17% respectively. The 5, 10 and 15-year recurrence free survival (RFS) rates were respectively 68.6%, 47.3% and 40.8% in group 1, 73.3%, 66.2% and 49.5% in group 2 and 68.8%, 57.5% and 47.7% in group 3 (log rank P=0.47). CONCLUSIONS: Recipient BMI at time of transplant and during follow-up didn't impact the incidence of HCC recurrence nor long-term patient survival, irrespective to the status of the patients and their tumor characteristic at time of LT. The present study clearly confirms that obesity should not be considered, when selecting patients with HCC to LT, as a predictive factor of recurrence.

RESUMO

BACKGROUND: While inflow control can be easily applied by Pringle maneuver, outflow control of the left liver has not been formally described. We report here a safe and reproductible technique of middle and left hepatic veinous trunk control (MLHVC) before parenchymal transection during laparoscopic left hepatectomy. METHODS: A retrospective review of laparoscopic liver resection was conducted from January 2013 to March 2018 from our prospective database. All cases of laparoscopic left hepatectomy (LLH) were included, and intra- and postoperative outcomes data collected. We collected cases where the middle and left hepatic vein trunk control has been attempted and clamping used, and we analyzed outcomes associated with this maneuver. RESULTS: MLHVC was attempted in 28 cases (77.8) of the 36 LLH identify in a monocentric study. It was technically not feasible only in 3 cases (8.3%) and clamping applied in 15 cases (41.7%). No significant intraoperative unexpected event occurred. CONCLUSION: We present here a technique for left liver outflow control that can be safely added to the armamentarium of laparoscopic liver surgery.

RESUMO

BACKGROUNDS AND AIMS: Postoperative early recurrence after hepatic resection for hepatocellular carcinoma (HCC) poses a challenge to surgeons, and the effect of a surgical margin is still controversial. This study aimed to identify an ideal margin to prevent early recurrence. METHODS: A total of 226 consecutive patients who underwent primary curative hepatic resection for solitary and primary HCC were enrolled. The definition of early recurrence was determined using the minimum P value approach. Logistic regression analysis was used to identify the risk factors of early recurrence. The receiver-operating characteristic (ROC) curve was used to identify the optimal cut-off of the surgical margin and early recurrence. RESULTS: Recurrence within 8 months induced the poorest overall survival (P = 2×10-15). ROC analysis showed that the optimal cut-off value of the surgical margin was 7 mm. The risk factors of early recurrence (≤ 8-month recurrence) were preoperative alpha-fetoprotein levels ≥ 100 ng/ml (Odds ratio [OR] 4.92 [2.28-10.77], P < 0.0001) and a surgical margin < 7 mm (OR 3.09 [1.26-8.85], P = 0.01) by multivariable analysis. The probability of early recurrence ranged from 5.0% in the absence of any factors to 43.5% in the presence of both factors. Among patients with alpha-fetoprotein levels ≥ 100 ng/ml, non-capsule formation, or microvascular invasion, there was a significant difference in 5-year overall survival between surgical margins of < 7 mm and ≥ 7 mm. CONCLUSIONS: A > 7-mm margin is important to prevent early recurrence. Patients with HCC and alpha-fetoprotein levels > 100 ng/ml, non-capsule formation, or microvascular invasion may have a survival benefit from a ≥ 7-mm margin.

BACKGROUND: Hepatocellular carcinoma (HCC) is currently the first indication of liver transplantation (LT) in Europe and Asia-Pacific region and the third in the United States. HCC recurrence is the main complication affecting short- and medium-term outcomes after LT. METHODS: A total of 433 consecutive adult recipients transplanted for HCC between 2000 and 2017 (mean age: 57.8 ± 8.5 y; 83.8% were males) with a mean follow-up of 74.6 ± 58.6 months were included. Patients had to meet Milan criteria and, since 2014, alpha-fetoprotein score to be listed. Patients with HCC recurrence were classified into early (≤2 y) and late recurrence (>2 y) and were retrospectively reviewed. RESULTS: Patients who developed recurrence (75 patients, 17%) had more tumors outside Milan and University of California San Francisco criteria, high alpha-fetoprotein score, and microvascular invasion at pathology. Early recurrence developed in 46 patients (61.3%); the overall 5- and 10-year survival rates of these patients from time of LT were 6.7% and 0%, which were significantly lower than those with late recurrence 64.0% and 27.1%, respectively (P < 0.001). The median survival times from the diagnosis of HCC recurrence were 15 and 17 months, respectively, in the 2 groups (P < 0.001). Multivariable Cox regression analysis identified alcoholic cirrhosis as etiology of the underlying liver disease (hazard ratio [HR] = 3.074; P = 0.007), bilobar tumor at time of LT (HR = 2.001; P = 0.037), and a tumor size (>50 mm) in the explant (HR = 1.277; P = 0.045) as independent predictors of early recurrence. CONCLUSIONS: Improving the prediction of early HCC recurrence could optimize patient selection for LT, potential adjuvant therapy with new targeted drugs and hence, improve long-term survival.

RESUMO

OBJECTIVE: To compare HOPE and NRP in liver transplantation from cDCD. SUMMARY OF BACKGROUND DATA: Liver transplantation after cDCD is associated with higher rates of graft loss. Dynamic preservation strategies such as NRP and HOPE may offer safer use of cDCD grafts. METHODS: Retrospective comparative cohort study assessing outcomes after cDCD liver transplantation in 1 Swiss (HOPE) and 6 French (NRP) centers. The primary endpoint was 1-year tumor-death censored graft and patient survival. RESULTS: A total of 132 and 93 liver grafts were transplanted after NRP and HOPE, respectively. NRP grafts were procured from younger donors (50 vs 61 years, P < 0.001), with shorter functional donor warm ischemia (22 vs 31 minutes, P < 0.001) and a lower overall predicted risk for graft loss (UK-DCD-risk score 6 vs 9 points, P < 0.001). One-year tumor-death censored graft and patient survival was 93% versus 86% (P = 0.125) and 95% versus 93% (P = 0.482) after NRP and HOPE, respectively. No differences in non-anastomotic biliary strictures, primary nonfunction and hepatic artery thrombosis were observed in the total cohort and in 32 vs. 32 propensity score-matched recipients CONCLUSION:: NRP and HOPE in cDCD achieved similar post-transplant recipient and graft survival rates exceeding 85% and comparable to the benchmark values observed in standard DBD liver transplantation. Grafts in the HOPE cohort were procured from older donors and had longer warm ischemia times, and consequently achieved higher utilization rates. Therefore, randomized controlled trials with intention-to-treat analysis are needed to further compare both preservation strategies, especially for high-risk donor-recipient combinations.

RESUMO

BACKGROUND: FOLFIRINOX is a pillar first-line regimen in the treatment of pancreatic cancer. Historically, biliary tract cancer (BTC) and pancreatic cancer have been treated similarly with gemcitabine alone or combined with a platinum compound. With growing evidence supporting the role of fluoropyrimidines in the treatment of BTC, we aimed at assessing the outcomes of patients (pts) with BTC on frontline FOLFIRINOX. METHODS: We retrospectively analyzed data of all our consecutive patients with locally advanced (LA) or metastatic (M) BTC who were registered to receive FOLFIRINOX as a first-line therapy between 12/2013 and 11/2017 at Paul Brousse university hospital. The main endpoints were Overall Survival (OS), Time-to-Progression (TTP), best Objective Response Rate (ORR), Disease Control rate (DCR), secondary macroscopically-complete resection (res) and incidence of severe (grade 3-4) toxicity (tox). RESULTS: There were 17 male (40%) and 25 female (60%) pts. aged 36 to 84 years (median: 67). They had PS of 0 (55%) or 1 (45%), and intrahepatic cholangiocarcinoma (CCA) (21 pts., 50%), gallbladder carcinoma (8 pts., 19%), perihilar CCA (7 pts., 17%), distal CCA (4 pts., 10%) and ampulloma (2 pts., 5%). BTC was LA or M in 10 (24%) and 32 pts. (76%) respectively. Biliary stent was placed in 14 pts. (33%). A median of 10 courses was given with median treatment duration of 6 months. There were no untoward toxicity issues, with no febrile neutropenia, emergency admission for toxicity or toxic death. We observed 12 partial responses (29%) and 19 disease stabilisations (45%). Six patients (14%) underwent secondary R0-R1 resection. Median TTP was 8 months [95%CL, 6-10] and median OS was 15 months [13-17]. Patients undergoing secondary resection displayed a 3-y disease-free rate of 83%. CONCLUSIONS: First-line FOLFIRINOX offers promising results in patients with LA and M-BTC. It deserves prospective evaluation to further improve outcomes for advanced BTC.

RESUMO

Laparoscopic left pancreatectomy for pancreatic cancer has increased worldwide over the last decade. However, this procedure is technically challenging compared with traditional laparoscopic left pancreatectomy and still needs to be better standardized. On this video, we describe the standardization of the technique at our center, highlighting some technical tips and tricks.
