The study purpose is to external validate the surgical risk calculator (SRC) and the AFC\/OCC score and to create a score for risk stratification. Patients and methods: Overall, 435 patients with emergency surgery for OCC were included in this retrospective study. We used statistical methods suitable for the aimed purpose. Results: Postoperative mortality was 11.72%. SRC performance: strong discrimination (AUC = 0.864) and excellent calibration (11.80% predicted versus 11.72% observed); AFC\/OCC score performance: adequate discrimination (AUC = 0.787) and underestimated mortality (6.93% predicted versus 11.72% observed). We identified nine predictors of postoperative mortality: age &gt; 70 years, CHF, ECOG &gt; 2, sepsis, obesity or cachexia, creatinine (aN) or platelets (aN), and proximal tumors (AUC = 0.947). Based on the score, we obtained four risk groups of mortality rate: low risk (0.7%)\u20140\u20132 factors, medium risk (12.5%)\u20143 factors, high risk (40.0%)\u20144 factors, very high risk (84.4%)\u20145\u20136 factors. Conclusions: The two scores were externally validated. The easy identification of predictors and its performance recommend the mortality score of the Clinic County Emergency Hospital of Gala\u021bi\/OCC for clinical use.<\/jats:p>","DOI":"10.3390\/ijerph192013513","type":"journal-article","created":{"date-parts":[[2022,10,19]],"date-time":"2022-10-19T20:32:23Z","timestamp":1666211543000},"page":"13513","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Mortality Risk Stratification in Emergency Surgery for Obstructive Colon Cancer\u2014External Validation of International Scores, American College of Surgeons National Surgical Quality Improvement Program Surgical Risk Calculator (SRC), and the Dedicated Score of French Surgical Association (AFC\/OCC Score)"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7081-9490","authenticated-orcid":false,"given":"Raul","family":"Mihailov","sequence":"first","affiliation":[{"name":"Clinic Surgery Department, Dunarea de Jos University, 800216 Galati, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dorel","family":"Firescu","sequence":"additional","affiliation":[{"name":"Clinic Surgery Department, Dunarea de Jos University, 800216 Galati, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georgiana Bianca","family":"Constantin","sequence":"additional","affiliation":[{"name":"Morphological and Functional Sciences Department, Dunarea de Jos University, 800216 Galati, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oana Mariana","family":"Mihailov","sequence":"additional","affiliation":[{"name":"Clinic Medical Department, Dunarea de Jos University, 800216 Galati, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Petre","family":"Hoara","sequence":"additional","affiliation":[{"name":"General Surgery Department, Carol Davila University, 050474 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8799-4524","authenticated-orcid":false,"given":"Rodica","family":"Birla","sequence":"additional","affiliation":[{"name":"General Surgery Department, Carol Davila University, 050474 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Traian","family":"Patrascu","sequence":"additional","affiliation":[{"name":"General Surgery Department, Carol Davila University, 050474 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eugenia","family":"Panaitescu","sequence":"additional","affiliation":[{"name":"Medical Informatics and Biostatistics Department, Carol Davila University, 050474 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,19]]},"reference":[{"key":"ref_1","unstructured":"(2022, July 22).
