What is the minimum follow-up rate required for eligible cases from the most current year of completed cases through 15 years?

The minimum follow-up rate required for eligible cases from the most current year of completed cases through 15 years is 80 percent. This percentage is crucial for ensuring the completeness and accuracy of cancer data, which directly impacts patient outcomes and the effectiveness of treatment protocols. A follow-up rate of at least 80 percent helps to ensure that a sufficient number of cases are being tracked for a robust analysis of patient survival rates and the effectiveness of different treatment options. Lower follow-up rates could lead to biased or incomplete data, making it difficult to draw reliable conclusions from cancer studies and registries. Therefore, maintaining this threshold is essential for the integrity of oncology data collection and research.
