Background:Hepatectomy in patients with large tumor load may result in postoperative liver failure and associated complications due to excessive liver parenchyma *** two-stage hepatectomy(TSH)and associating liver partition and portal vein ligation for staged hepatectomy(ALPPS)technique are possible solutions to this *** liver metastases(CRLM)is the most frequent indication,and there is a need to assess outcomes for both techniques to improve surgical and long-term oncological outcomes in these ***:A single-center retrospective study was designed to compare TSH with ALPPS in patients with initially unresectable bilateral liver tumors between January 2005 and January *** was performed from January 2012 onwards as the technique of ***-term overall survival(OS)and disease-free survival(DFS)were evaluated as primary outcome in CRLM *** morbidity,mortality and liver growth in all patients were also ***:A total of 38 staged hepatectomies were performed:17 TSH and 21 *** resection rate was 76.5%(n=13)in the TSH group and 85.7%(n=18)in the ALPPS group(P=0.426).Overall major morbidity(Clavien-Dindo≥3 a)(stage 1+stage 2)was 41.2%(n=7)in TSH and 33.3%(n=7)in ALPPS patients(P=0.389),and perioperative 90-day mortalities were 11.8%(n=2)vs.19.0%(n=4)in each group,respectively(P=0.654).Intention-to-treat OS rates at 1 and 5 years in CRLM patients for TSH(n=15)were 80%and 33%,and for ALPPS(n=17)76%and 35%,*** rates at 1 and 5 years were 36%and 27%in the TSH group vs.33%and 27%in the ALPPS group,***:ALPPS is an effective alternative to TSH in bilateral affecting liver tumors,allowing higher resection rate,but patients must be carefully *** CRLM patients similar long-term OS and DFS can be achieved with both techniques.

Latin-America (LATAM) is the second region in gastric cancer incidence;gastric adenocarcinoma (GA) represents 95% of all cases. We provide a mutational landscape of GA highlighting a) germline pathogenic variants associated with hereditary GA, b) germline risk variants associated with sporadic GA, and c) somatic variants present in sporadic GA in LATAM, and analyze how this landscape can be applied for precision medicine. We found that Brazil, Chile, Colombia, Mexico, Peru, and Venezuela are the countries with more published studies from LATAM explicitly related to GA. Our analysis displayed that different germline pathogenic variants for the CDH1 gene have been identified for hereditary GA in Brazilian, Chilean, Colombian, and Mexican populations. An increased risk of developing somatic GA is associated with the following germline risk variants: IL-4, IL-8, TNF-α, PTGS2, NFKB1, RAF1, KRAS and MAPK1 in Brazilian;IL-10 in Chilean;IL-10 in Colombian;EGFR and ERRB2 in Mexican, TCF7L2 and Chr8q24 in Venezuelan population. The path from mutational landscape to precision medicine requires four development levels: 1) Data compilation, 2) Data analysis and integration, 3) Development and approval of clinical approaches, and 4) Population benefits. Generating local genomic information is the initial padlock to overcome to generate and apply precision medicine.
