Seventh edition of the cancer staging manual and stage grouping of lung cancer: quick reference chart and diagrams.

Abstract

Lung cancer remains the most common cause of cancer-related death in the United States. TNM staging, which is an important guide to the prognosis and treatment of lung cancer, has been revised recently. In this article, we propose a quick reference chart and diagrams that consolidate TNM staging information in a simple format. The current classification of lymph node stations and zones is illustrated as well.
