The College of American Pathologists (CAP) released updates to 23 cancer protocols to ensure that laboratories remain aligned with best practices in oncology and patient care.
These updates reflect the latest guidance from the American Joint Committee on Cancer and the World Health Organization.
Key changes to cancer diagnosis protocols include:
- Gastrointestinal: New questions related to treatment effects, histologic types, and tumor size to better address multifocal invasive carcinoma with additional neoplasms.
- Pediatric: Revised accreditation requirement statements (biopsy protocols), reformatting of explanatory notes, and the addition of reference range metadata (eCP only).
- Kidney Resection: Refined language in the lymphatic and/or vascular invasion question.
- Bladder Biopsy: Expanded answer options for the muscularis propria question to better define tumor involvement.
- Pleural Mesothelioma: Histologic grade reporting required only for epithelioid mesothelioma.
- Breast Biomarker Reporting: Updated test method questions for conditional reporting.
