However, HCC-related mortality post-LT remains a significant concern, with up to 10% of cases reported in international series. Identifying risk factors for adverse clinical outcomes is essential. We hypothesized that post-LT HCC-related mortality rates are higher in patients with a high (≥ 42) Comprehensive Complication Index (CCI) calculated at discharge. This study aims to compare post-LT HCC-related mortality rates between two groups of patients with high versus low CCI following LT for HCC. This study included data from seven collaborative European centers. A cohort of 1121 HCC patients transplanted between 2005 and 2019, surviving more than six months post-LT, was analyzed retrospectively. Patients were divided into two groups based on the CCI at discharge: Low-CCI Group (n = 942, 84.0%) and High-CCI Group (n = 179, 16.0%). An inverse probability of treatment weighting (IPTW) approach was applied for analysis. In the post-IPTW cohort, four multivariable logistic regression models with mixed effects identified independent risk factors for HCC-related death, overall death, recurrence, and early recurrence. A CCI score of ≥ 42 emerged as an independent risk factor across all models. Specifically, CCI ≥ 42 was associated with increased odds of HCC-related death (OR = 3.35; P < 0.0001), overall death (OR = 2.63; P < 0.0001), overall recurrence (OR = 2.09; P = 0.001), and early recurrence (OR = 1.88; P = 0.02). A CCI score at discharge should be considered a critical factor for recurrence and HCC-related mortality risk. Incorporating CCI into standard post-LT predictive models may enhance prognostic accuracy for adverse HCC outcomes.</p>","PeriodicalId":23391,"journal":{"name":"Updates in Surgery","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143383139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fifty-nine oligometastatic lung cancer cases operated on in our clinic between January 2015 and January 2024 were retrospectively examined. Demographic characteristics, metastasis type, metastasis locations, treatments applied, location of the primary tumor, histological type of the tumor, and metastasectomy status of the patients included in the study were evaluated. All patients underwent surgery for primary lung cancer. Generally, the mass in the lung was excised first. The metastasis was then removed. When brain surgery became a priority in some brain metastases, the metastasis was first removed and then the lesion in the lung was completely removed. In patients with oligometastasis, the tumor was either completely removed surgically or a complete cure was achieved with radiotherapy. All patients were stage 4a patients with metastases. The median age of the patients was 61 (36-76) years. 31 (52.6%) of the patients were aged 60 and over. 96.6% (n:57) of the patients were male and 3.4% (n:2) were female. Histopathological diagnosis was 35.6% squamous cell carcinoma (SCC) and 42.4% adeno cancer. 61.0% of the patients had brain metastases and 23.7% had adrenal metastases.
