Which of the following is an example of a confidential data item in a cancer registry report?

• A. Stage of cancer
• B. Address at diagnosis
• C. Type of treatment
• D. Patient age

Answer: (B)

Confidential data items in a cancer registry report are those that, if disclosed, could potentially lead to the identification of an individual patient and infringe upon their privacy. The address at diagnosis is a prime example of such sensitive information. Knowing a patient's residential address allows for the possibility of pinpointing their identity, which is why it falls under strict confidentiality regulations. In contrast, while stage of cancer, type of treatment, and patient age are important clinical data points that contribute to cancer care and research, they do not necessarily identify an individual directly. These details can often be aggregated or anonymized to protect patient identity. Therefore, they are generally considered less sensitive than a patient's specific address. Addresses are usually protected to maintain patient confidentiality and comply with privacy laws, making them a critical aspect of data handling in cancer registries.
