Volume-outcome relationship in penile cancer treatment: a population based patterns of care and outcomes study from Australia

Abstract

OBJECTIVES: To study the patterns of care of penile cancer diagnosed in the state of New South Wales (NSW) over a 10 year period and determine factors that are associated with differences in survival. PATIENTS AND METHODS: All invasive penile cancer diagnosed between 2001 and 2009 in NSW, Australia, were identified from the Central Cancer Registry. Records of treatment from the Admitted Patient Data Collection and deaths from the Registry of Births Deaths and Marriages were electronically linked. Predictors of receiving an inguinal lymph node dissection (ILND) were analysed using multivariable logistic regression. Survival analyses were performed with Kaplan-Meier and Cox proportional hazard..
