What type of data is primarily collected by a tumor registry?

A tumor registry primarily collects comprehensive data that includes patient demographics, tumor characteristics, treatment information, and follow-up outcomes. This type of information is essential for tracking cancer trends, improving treatment protocols, and conducting epidemiological research. The demographic data helps in understanding which populations are affected, while tumor characteristics provide insights into the type and stage of cancer, which is crucial for determining treatment pathways.

Treatment data allows for the examination of various modalities and their effectiveness across different patient groups, enhancing the overall understanding of cancer management. Follow-up information is vital for assessing patient outcomes, identifying recurrent cases, and monitoring long-term survival rates. This holistic approach ensures that registries can contribute valuable information to improve cancer care and inform public health initiatives.

In contrast, the other options, such as clinical trial outcomes, financial information, and radiology results, do not encapsulate the broad range of data that registries focus on. While these may be relevant in specific contexts, they do not represent the core data collected by tumor registries, which is centered around the patient, the disease, and treatment outcomes.
