Tumor upstaging in invasive melanoma is associated with changes in clinical management and worse prognosis.

Background: The clinical implications and prognostic outcomes associated with tumor upstaging in invasive melanoma have not been well established.

Objectives: To determine the frequency of tumor upstaging in invasive melanoma, identify risk factors, and assess its impact on clinical management and outcomes.

Methods: A retrospective study using data from a statewide Surveillance Endpoints and End Results-affiliated cancer registry between 2014 and 2018 was performed.

Differences in outcomes by race/ethnicity after thoracic surgery in a large integrated health system.

Background: Disparities exist throughout surgery. We aimed to assess for racial/ethnic disparities among outcomes in a large thoracic surgery patient population.

Methods: We reviewed all thoracic surgery patients treated at our integrated health system from January 1, 2016-December 31, 2020.
