Analysis of factors affecting short-term results in elderly patients undergoing elective surgical resection for stage I-II colon cancer

AIM: The aim of this study was to analyze the influence of comorbidities and to compare the short-term results of elective surgical resection of stage I-II colon adenocarcinoma in elderly ( 6565 years) versus younger patients. PATIENTS AND METHODS: Two groups of sex-matched younger and older patients were compared: Group A: N=36, median age 58 (range=43-65) years; and group B: N=67, median age 73 (range=66-86) years. RESULTS: Overall, 71 out of 103 (68.9%) patients had one or more comorbidities. A greater number of older patients had an American Society of Anesthesiologists (ASA) score >2 (p=0.004) and were on multiple medications (polypharmacy) (p=0.016), but the distribution of the other parameters was similar (p 650.05). Intra- and postoperative complications in group A vs. B occurred in 25.0% vs. 26.9%, and 47.2% vs. 64.2%, respectively (p 650.05). CONCLUSION: Elderly patients with colon cancer scheduled to elective surgical resection should not be considered at increased risk of intra- or short-term postoperative complications with respect to younger patients. However, they require careful individual preoperative evaluation because they are usually polypharmacy users and have a higher ASA score
