Abstract

Background: The aim of this study was to compare the stage-for-stage overall (OS) and recurrence-free (RFS) survival between adult and pediatric/adolescent colon cancer patients. Study design: A retrospective review of pediatric/adolescent patients less than 25 years old, treated between 1991 and 2017 at University of Texas MD Anderson Cancer Center, was compared with a prospectively maintained database of adult patients. Outcomes variables were compared, and OS and RFS were estimated using the Kaplan-Meier method and compared between groups using the log rank test and multivariable Cox models. Results: The cohort contained 94 pediatric patients and 765 adult patients. Overall, the 3-year OS rates for adult and pediatric patients, respectively, were 90% and 41.92% (95% CI 87% to 92%) (p < 0.0001), and the 3-year RFS rates were 78% and 32% (p < 0.0001). The stage-for-stage 5-year OS rates for adult vs pediatric patients were: Stage 1: 96% vs 100% (p = 0.793); stage 2: 90% vs 64% (p < 0.0001); stage 3: 85% vs 58% (p < 0.0001); stage 4; 55% vs 16% (p < 0.0001). The stage-for-stage 5-year RFS rates for adults vs children were: stage 1: 95% vs 100%; stage 2: 85% vs 55% (p = 0.0002); stage 3: 73% vs 31% (p < 0.0001); stage 4: 27% vs 5% (p < 0.0001). Pediatric/adolescent patients had a higher risk of recurrence or death than adult patients on multivariate analysis (hazard ratio [HR] 2.312, 95% CI: 1.615 to 3.313 (p < 0.0001). Peritoneal metastasis was significantly higher in pediatric patients. (p = 0.00001) Conclusions: Stage-for-stage, pediatric/adolescent patients had shorter 3- and 5-year OS and RFS rates than adult patients. Peritoneal disease and carcinomatosis were significantly higher in pediatric, adolescent, and young adult patients less than 25 years old. Predisposing conditions, such as polyposis or congenital colon disease, did not contribute to this difference.
