This study aimed to evaluate perioperative and survival outcomes in octogenarians undergoing curative open colorectal surgery. Methods: This single-center observational cohort study included consecutive patients aged \u226580 years who underwent curative open colorectal cancer surgery between 2013 and 2024. Frailty was assessed using the 5-item modified frailty index (mFI-5). Postoperative morbidity, 30-day mortality, and long-term overall survival were analyzed. Outcomes were compared between colon and rectal resections. Exploratory discrimination analyses assessed the ability of age, frailty, and major comorbidities to identify postoperative morbidity. Survival was assessed using Kaplan\u2013Meier analysis. Results: A total of 112 patients were included (mean age 83.1 \u00b1 2.8 years; 54.5% male), of whom 90.2% were classified as frail (mFI-5 \u2265 1). Overall postoperative morbidity occurred in 41.9% of patients and 30-day mortality was 4.5%. No significant differences in morbidity or mortality were observed between colon and rectal resections. ROC analyses demonstrated limited discriminatory ability for postoperative morbidity across all evaluated variables, with age showing the highest AUC at 0.590. Estimated OS at 1, 3, and 5 years was 81.8%, 72.7%, and 58.2% in non-frail patients and 86.1%, 64.7%, and 47.0% in frail patients, respectively (log-rank p = 0.841). Conclusions: Major open colorectal surgery in octogenarians is associated with acceptable perioperative morbidity and mortality and favorable long-term survival despite high frailty burden.<\/jats:p>","DOI":"10.3390\/medsci14010101","type":"journal-article","created":{"date-parts":[[2026,2,19]],"date-time":"2026-02-19T13:47:02Z","timestamp":1771508822000},"page":"101","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Real-World Results of Curative Open Colorectal Cancer Surgery in Octogenarians: Long-Term Survival Despite High Frailty Burden"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7767-0975","authenticated-orcid":false,"given":"Stefan","family":"Morarasu","sequence":"first","affiliation":[{"name":"Grigore T Popa University of Medicine and Pharmacy, Iasi 700115, Romania"},{"name":"2nd Department of Surgical Oncology, Regional Institute of Oncology, Iasi 700483, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bogdan","family":"Condurache","sequence":"additional","affiliation":[{"name":"Grigore T Popa University of Medicine and Pharmacy, Iasi 700115, Romania"},{"name":"2nd Department of Surgical Oncology, Regional Institute of Oncology, Iasi 700483, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristian Ene","family":"Roata","sequence":"additional","affiliation":[{"name":"Grigore T Popa University of Medicine and Pharmacy, Iasi 700115, Romania"},{"name":"2nd Department of Surgical Oncology, Regional Institute of Oncology, Iasi 700483, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Maria","family":"Musina","sequence":"additional","affiliation":[{"name":"Grigore T Popa University of Medicine and Pharmacy, Iasi 700115, Romania"},{"name":"2nd Department of Surgical Oncology, Regional Institute of Oncology, Iasi 700483, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wee Liam","family":"Ong","sequence":"additional","affiliation":[{"name":"Grigore T Popa University of Medicine and Pharmacy, Iasi 700115, Romania"},{"name":"2nd Department of Surgical Oncology, Regional Institute of Oncology, Iasi 700483, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriel Mihail","family":"Dimofte","sequence":"additional","affiliation":[{"name":"Grigore T Popa University of Medicine and Pharmacy, Iasi 700115, Romania"},{"name":"2nd Department of Surgical Oncology, Regional Institute of Oncology, Iasi 700483, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9749-0610","authenticated-orcid":false,"given":"Sorinel","family":"Lunca","sequence":"additional","affiliation":[{"name":"Grigore T Popa University of Medicine and Pharmacy, Iasi 700115, Romania"},{"name":"2nd Department of Surgical Oncology, Regional Institute of Oncology, Iasi 700483, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,19]]},"reference":[{"key":"ref_1","first-page":"209","article-title":"Global cancer statistics 2020: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries","volume":"71","author":"Sung","year":"2021","journal-title":"CA Cancer J.
