Data Set for the Reporting of Carcinomas of the Hypopharynx, Larynx, and Trachea: Explanations and Recommendations of the Guidelines From the International Collaboration on Cancer Reporting

The International Collaboration on Cancer Reporting is a nonprofit organization whose mission is to develop evidence-based, universally available surgical pathology reporting data sets. Standardized pathologic reporting for cancers facilitates improved communication for patient care and prognosis and the comparison of data between countries to progressively improve clinical outcomes. Laryngeal cancers are often accompanied by significant morbidity, although surgical advances (such as transoral endoscopic laser microresection and transoral robotic surgery) provide new alternatives. The anatomy of the larynx is complex, with an understanding of the exact anatomic sites and subsites, along with recognizing anatomic landmarks, being crucial to classification and prognostication. This review outlines the data set developed for the histopathology reporting in Carcinomas of the Hypopharynx, Larynx and Trachea and discusses the main elements required and recommended for reporting.
