Core Tip

Core tip: This paper serves to show how changes in practice patterns evolve over time. The adoption of these practice patterns differ across institution type, and the role of appropriate clinical staging is often not included. In order for proper treatments to be initiated, we not only need data substantiated by level one evidence, but we also need proper clinical staging so we can ensure appropriate therapies are delivered to these patients.
