Which item is NOT considered a primary source for initial casefinding?

The item considered not to be a primary source for initial casefinding is oncology treatment summaries. Initial casefinding involves identifying newly diagnosed cancer cases and typically relies on sources that provide direct evidence of the diagnosis.

Oncology treatment summaries, while valuable in the overall context of patient care and management, are usually generated after initial treatment has commenced and may not reflect the initial diagnosis. They summarize the treatment given, but they do not serve as a primary means of ascertaining if a patient has a newly diagnosed cancer, which is the primary focus during the casefinding process.

In contrast, radiology logs, surgical pathology reports, and patient referrals are all primary sources of information that directly relate to identifying new cancer cases, as they often contain initial diagnostic assessments or evidence of malignancy that is crucial for reporting and tracking cancer cases at the onset.
