Lung Metastases Versus Second Primary Lung Cancers in Patients with Primary Urothelial Carcinoma of the Bladder: A National Population-Based Assessment.

ABSTRACT:

Background

The work-up and diagnosis of indeterminate lung nodules at time of bladder cancer diagnosis may delay or change treatment.

Objective

To quantify the incidence of synchronous and metachronous lung cancers in adults with bladder cancer and compare these rates to the incidence of bladder cancer metastases in the lung.

Methods

We retrospectively analyzed all adults diagnosed with bladder cancer in the Surveillance, Epidemiology and End Results (SEER) registry (2010- 2015) and identified second primary lung cancers defined as being either synchronous (diagnosed within 6 months of bladder cancer diagnosis) or metachronous (more than 6 months following index bladder cancer diagnosis). The risk of second primary lung cancers were reported as a standardized incidenc
