According to the Commission on Cancer, what is the maximum number of cancer registry cases that should undergo quality control?

  1. 150

  2. 200

  3. 300

  4. 400

The correct answer is: 300

The maximum number of cancer registry cases that should undergo quality control, as established by the Commission on Cancer, is 300. This number is significant because it provides a standardized measure for evaluating the accuracy and completeness of cancer data collected by registries. Conducting quality control on a set number of cases ensures that registries maintain a consistent level of data quality and can identify areas that need improvement. By budgeting resources for quality control within this framework, cancer registries can effectively monitor and enhance their data collection processes, ultimately leading to more reliable cancer statistics. This practice is essential for supporting clinical treatment decisions, research, and public health policies. The choice of 300 cases reflects a balance between the ability to adequately assess data quality and the logistical constraints that registries may face.
