Lung cancer(LC)is a prevalent and fatal malignancy,with high incidence and mortality rates.1 ATP binding cassette(ABC)transporters,a superfamily of integral membrane proteins,use ATP hydrolysis to facilitate substrate transport across cellular membranes.2 The pivotal role of ABC transporters in tumorigenesis was initially established by Mochida,3 who demonstrated that the loss of ABCB1 suppresses intestinal polyp formation and tumor progression in *** investigations have reported correlations between ABC transporters and the tumor microenvironment and cancer immunotherapy response,suggesting their modulatory effects on tumor progression and immunotherapy.

BACKGROUND Bile leakage is a common and serious complication of open hepatectomy for the treatment of biliary tract *** To evaluate the incidence,risk factors,and management of bile leakage after open hepatectomy in patients with biliary tract *** We retrospectively analyzed 120 patients who underwent open hepatectomy for biliary tract cancer from February 2018 to February *** leak was defined as bile drainage from the surgical site or drain or the presence of a biloma on *** incidence,severity,timing,location,and treatment of the bile leaks were *** risk factors for bile leakage were analyzed using univariate and multivariate logistic regression *** The incidence of bile leak was 16.7%(20/120),and most cases were grade A(75%,15/20)according to the International Study Group of Liver Surgery *** median time of onset was 5 d(range,1-14 d),and the median duration was 7 d(range,2-28 d).The most common location of bile leakage was the cut surface of the liver(70%,14/20),followed by the anastomosis site(25%,5/20)and the cystic duct stump(5%,1/20).Most bile leaks were treated conservatively with drainage,antibiotics,and nutritional support(85%,17/20),whereas some required endoscopic retrograde cholangiopancreatography with stenting(10%,2/20)or percutaneous transhepatic cholangiography with drainage(5%,1/20).Risk factors for bile leakage include male sex,hepatocellular carcinoma,major hepatectomy,blood loss,and blood *** Bile leakage is a frequent complication of open hepatectomy for biliary tract ***,most cases are mild and can be conservatively *** sex,hepatocellular carcinoma,major hepatectomy,blood loss,and blood transfusion were associated with an increased risk of bile leak.
