Cases are considered lost to follow-up if no contact has been made within how many months?

• A. 6 months
• B. 12 months
• C. 15 months
• D. 24 months

Answer: (C)

Cases are classified as lost to follow-up when there has been no contact with the patient or their healthcare provider within a specified time frame. In many cancer registry operations, this period is typically 15 months. This timeframe allows for a reasonable duration to attempt multiple methods of reaching the patient or their representative. If no contact occurs within this time, the case is deemed lost to follow-up, indicating that there is insufficient information to continue tracking the patient's status. This classification is crucial for maintaining accurate data in cancer registries, as it helps determine the completeness and reliability of survival outcomes and treatment patterns. Other time frames may not effectively capture the complexity of patient follow-up and can lead to either premature loss to follow-up designations or excessive delays in classification.
