Abstract
Background: Colorectal cancer primarily affects older adults and poses treatment challenges due to age-related comorbidities and frailty, which hinder surgical and chemotherapy options for many elderly patients. This study aims to analyze treatment and disease patterns in elderly colorectal cancer patients, aged over 80 years old, to inform personalized therapies that accommodate their unique clinical needs and improve their outcomes. Patients and Methods: The medical records of all patients aged 80 years old and above, and those aged 65 to 75 years old, who were diagnosed with colorectal cancer at a cancer center in Canada over a seven year period, were retrospectively reviewed. Results: No significant differences in the initial presentation, location, grade or stage at colorectal cancer diagnosis were observed between age groups. Patients aged 80 years old and above were less likely to receive neoadjuvant and adjuvant chemotherapy treatments for stage II disease (19.2% versus. 58.6%, p = 0.002; 7.9% versus. 40.0%, p = 0.002). There were also differences in the intensity of chemotherapy received and the frequency of dose reductions (76.0% vs. 10.0%, p = 0.0001), neoadjuvant and adjuvant radiation therapy (34.6% vs. 65.5%, p = 0.02) and surgical management (83.7% vs. 95.3%, p = 0.006). Despite these differences in treatments, recurrence rates were not statistically significant between the two groups. However, overall survival was reduced in the older age group. Conclusions: Treatment plans for patients aged 80 years old and above should be tailored to the patient's colorectal cancer presentation, comorbidity status and life expectancy, weighing the impact of cancer treatments on the patient's short- and long-term outcomes.
