Early recurrence, defined as recurrence within one year after surgery, remains a major clinical concern. This study aimed to identify preoperative prognostic factors and develop a predictive model for early recurrence and overall survival in resected GBC patients. Methods: We retrospectively analyzed data from 251 patients who underwent curative-intent resection for GBC between 2008 and 2017. Logistic regression was used to identify preoperative factors associated with early recurrence. Significant variables were used to construct a nomogram, which was externally validated using a cohort of 176 patients from three independent tertiary centers. Results: The independent predictors of early recurrence included male sex, chronic liver disease, preoperative symptoms, elevated carcinoembryonic antigen (CEA), sarcopenic obesity, clinical T3 or higher stage, and suspected metastatic lymph nodes. The nomogram demonstrated strong predictive performance with an AUC of 0.872 (95% CI: 0.817\u20130.927) in internal validation and 0.703 (95% CI: 0.613\u20130.793) in external validation. Conclusions: We developed and externally validated a novel nomogram that predicts early recurrence in GBC using only preoperative factors. This model may support individualized risk assessment and aid surgeons and patients in shared decision-making prior to high-risk surgery.<\/jats:p>","DOI":"10.3390\/cancers17091450","type":"journal-article","created":{"date-parts":[[2025,4,28]],"date-time":"2025-04-28T05:21:31Z","timestamp":1745817691000},"page":"1450","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Development and External Validation of a Nomogram Predicting Early Recurrence of Gallbladder Cancer Using Preoperatively Available Prognosticators: A Korean Multicenter Retrospective Study"],"prefix":"10.3390","volume":"17","author":[{"given":"Hyun Jeong","family":"Jeon","sequence":"first","affiliation":[{"name":"Division of Hepatobiliary-Pancreatic Surgery, Department of Surgery, Kyungpook National University Chilgok Hospital, Kyungpook National University School of Medicine, Daegu 41404, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"So Kyung","family":"Yoon","sequence":"additional","affiliation":[{"name":"Department of Surgery, Soonchunhyang University Seoul Hospital, Soonchunhyang University College of Medicine, Seoul 04401, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2683-8795","authenticated-orcid":false,"given":"Boram","family":"Park","sequence":"additional","affiliation":[{"name":"Biomedical Statistics Center, Research Institute for Future Medicine, Samsung Medical Center, Seoul 06351, Republic of Korea"},{"name":"College of Medicine, Inha University, Incheon 22332, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyeong Seok","family":"Kim","sequence":"additional","affiliation":[{"name":"Division of Hepatobiliary-Pancreatic Surgery, Department of Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hochang","family":"Chae","sequence":"additional","affiliation":[{"name":"Division of Hepatobiliary-Pancreatic Surgery, Department of Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongbeom","family":"Kim","sequence":"additional","affiliation":[{"name":"Division of Hepatobiliary-Pancreatic Surgery, Department of Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang Hyun","family":"Shin","sequence":"additional","affiliation":[{"name":"Division of Hepatobiliary-Pancreatic Surgery, Department of Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"In Woong","family":"Han","sequence":"additional","affiliation":[{"name":"Division of Hepatobiliary-Pancreatic Surgery, Department of Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin Seok","family":"Heo","sequence":"additional","affiliation":[{"name":"Division of Hepatobiliary-Pancreatic Surgery, Department of Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Okjoo","family":"Lee","sequence":"additional","affiliation":[{"name":"Division of Hepatobiliary-Pancreatic Surgery, Department of Surgery, Soonchunhyang University Bucheon Hospital, Soonchunhyang University College of Medicine, Bucheon 14584, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"So Jeong","family":"Yoon","sequence":"additional","affiliation":[{"name":"Division of Hepatobiliary-Pancreatic Surgery, Department of Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 06351, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"271","DOI":"10.1038\/s41575-022-00726-3","article-title":"Updated epidemiology of gastrointestinal cancers in East Asia","volume":"20","author":"Huang","year":"2023","journal-title":"Nat.
