Aim:
The aim of this study was to evaluate the clinical outcomes of single-port surgery for colon cancer in octogenarians.
Materials And Methods:
A retrospective cohort study was performed on patients who underwent single-port surgery for colon cancer from 2010 to 2014 at a single institution. Patients were categorized into the following 3 groups according to age: ≤69 years (n=196), 70 to 79 years (n=143), and ≥80 years (n=86). Short-term and long-term outcomes were assessed among 3 groups.
Results:
The rate of overall postoperative complications in the octogenarian group did not differ significantly, compared with the other groups (20.9% in the octogenarians group vs. 14.3% in the ≤69 y group and 15.4% in the 70 to 79 y group, P=0.363). The 3-year relapse-free survival rates were similar among groups (83.9% in the octogenarians group vs. 87.8% in the ≤69 y group and 87.5% in the 70 to 79 y group, P=0.754). The 5-year overall survival rates were 79.8% in the octogenarians group, 89.9% in the ≤69 years group, and 81.7% in the 70 to 79 years group (P=0.063).
Conclusion:
Single-port surgery is safe, feasible, and can provide satisfactory oncological outcomes in octogenarians with colon cancer.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
Nursing Clinical Information System
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
