Abstract:
Cancer registries must focus on data capture which returns value while reducing resource burden with minimal loss of data. Identifying the optimum length of follow‐up data collection for patients with cancer achieves this goal. Methods A two‐step analysis using entropy calculations to assess information gain for each follow‐up year, and second‐order differences to compare survival outcomes between the defined follow‐up periods and lifetime follow‐up. A total of 391 567 adult cases, deidentified in the National Cancer Database and diagnosed in 1989. Comparisons examined a subset of 61 908 lung cancer cases, 48 387 colon and rectal cancer cases, and 64 134 breast cancer cases in adults. A total of 4133 pediatric cases were diagnosed in 1989 examining 1065 leukemia cases and 494 lymphoma cases. Results Annual increases in information gain fell below 1% after 16 years of follow‐up for adult cases and 9 years for pediatric cases. Comparison of second‐order differences showed 62% of the comparisons were similar between 15 years and lifetime follow‐up when examining restricted mean survival time. In addition, 90% of the comparisons were statistically similar when comparing hazard ratios. Conclusions Survival analysis using 15 years postdiagnosis follow‐up showed minimal differences in information gain compared to lifetime follow‐up.
