In hospital-based registries, what document is commonly used as the primary source for identifying new cancer cases?

• A. Pathology report
• B. Discharge summary
• C. Labs
• D. History and physical

Answer: (A)

The key point is that pathology reports provide definitive histologic confirmation of cancer, making them the most reliable source for identifying new cancer cases in hospital-based registries. A pathology report documents that malignant tissue has been confirmed, specifies the exact site and histology, and records the date of diagnosis, all of which are essential for accurate case ascertainment and coding (such as site and morphology). Because it confirms the presence of cancer with tissue evidence, it serves as the gold standard against which other sources are compared. Other documents can contribute useful information, but they are secondary to pathology for establishing a new case. Discharge summaries describe what happened during a hospital stay but may lack confirmation of malignancy. Laboratory results can indicate abnormal findings but do not prove cancer on their own. History and physicals provide initial assessments and may be incomplete or non-specific. In practice, registries often supplement pathology with additional sources to ensure complete capture, but the pathology report remains the primary, most reliable source for new cancer cases.
