Age-related differences in adjuvant chemotherapy use and outcomes in stage II colon cancer: a retrospective cohort study
This study analyzes age-related differences in adjuvant chemotherapy use and outcomes for stage II colon cancer patients. It reveals that younger and middle-aged patients are more likely to receive aggressive chemotherapy regimens, but without significant survival benefits compared to older patients, raising concerns about potential overtreatment.

The study highlights significant disparities in adjuvant chemotherapy utilization across age groups. Younger (18-49 years) and middle-aged (50-64 years) patients were substantially more likely to receive adjuvant chemotherapy (OR: 4.196 and 2.610 respectively, p<0.001) compared to older patients (65-75 years). This aggressive approach in younger cohorts often included multi-drug chemotherapy regimens (OR: 3.181 for young, 2.642 for middle-aged, p<0.001), while older patients frequently received less intensive or no adjuvant treatment. These findings suggest a treatment bias based on age, potentially influenced by perceived patient tolerance and comorbidity burden.
Despite the more aggressive treatment in younger and middle-aged patients, the study found no significant difference in overall survival rates across age groups (p=0.110). The 5-year OS rates were 92.5% for young, 86.0% for middle-aged, and 86.3% for older patients. This lack of survival benefit, despite higher chemotherapy use and intensity in younger cohorts, raises critical questions about the efficacy and necessity of such aggressive treatments in stage II colon cancer for these age groups. It implies that current treatment strategies may lead to overtreatment without improving patient outcomes.
Baseline characteristics revealed that younger patients presented with fewer comorbidities (16.1% vs. 37.2% vs. 54.9%, p<0.001) but showed worse differentiation types (25.8% vs. 7.4% vs. 6.1%, p=0.017) and a higher prevalence of microsatellite instability-high (MSI-H) status (21.51% vs. 9.10% vs. 10.57%, p=0.005). The presence of MSI-H status is generally associated with a favorable prognosis, which might partially explain why younger patients did not exhibit poorer survival despite worse differentiation. These biological differences underscore the need for age-specific considerations in treatment planning.

Real-World Implications: Avoiding Overtreatment in Younger Patients
A 45-year-old patient with high-risk stage II colon cancer, based on standard guidelines, would typically receive aggressive multi-drug adjuvant chemotherapy. However, this study's findings suggest that such intensive treatment may not yield superior survival outcomes compared to less aggressive or surgery-only approaches in this age group, especially if favorable prognostic markers like MSI-H are present.
This highlights the need for a more nuanced, individualized treatment strategy for younger patients. Instead of a blanket aggressive approach, AI-driven risk stratification and molecular profiling could help identify those who genuinely benefit from intensive chemotherapy, thereby reducing exposure to unnecessary toxicities and improving quality of life.
By adopting a personalized medicine approach, healthcare providers can optimize resource allocation, minimize patient burden, and potentially improve the long-term well-being of younger colon cancer patients without compromising oncological outcomes.

Roadmap to Personalized Oncology with AI
A phased approach to integrate AI-driven insights for age-specific colon cancer treatment.
Phase 1: Data Integration & Model Training (3-6 Months)
Consolidate existing patient data (pathology, demographics, treatment history) into a centralized system. Train AI models on historical outcomes to identify age-specific risk factors and treatment response patterns in stage II colon cancer.
Phase 2: Pilot Program & Clinical Validation (6-12 Months)
Deploy AI recommendations in a pilot program with a subset of patients. Clinicians validate AI-generated insights against current treatment protocols, refining models based on real-world effectiveness and patient feedback. Focus on identifying overtreatment risks in younger cohorts.
Phase 3: Full-Scale Implementation & Continuous Optimization (12+ Months)
Integrate AI decision support tools into routine clinical workflows. Continuously monitor patient outcomes and update AI models with new data to ensure ongoing relevance and improve predictive accuracy for age-stratified treatment decisions.
