Objective - To describe national trends and regional disparities in the rate of patients undergoing surgery for testicular cancer and to compare these with data from cancer registries. Materials and Methods - Hospital stays for surgical procedures for testicular cancer among patients residing in metropolitan France were selected from the national PMSI database for 1998–2008, using ICD-10 codes and surgical procedure codes. Results - 21,179 hospital stays corresponding to surgical treatment for testicular cancer were identified. The mean age at diagnosis was 37 years. The rate of patients undergoing surgery, standardized to the 2008 global population, was 6.7 per 100,000. An average annual increase of 2.5% in the rate was observed. Regional disparities in the rates of patients undergoing surgery were also observed (2004–2008). The highest rates were found in Alsace, Lorraine, Brittany, and Pays-de-la-Loire, and the lowest rates in Languedoc-Roussillon and Île-de-France. Discussion and Conclusion - The observed increase in the rate of patients undergoing surgery for testicular cancer is consistent with trend analyses of national incidence. The rate of patients undergoing surgery in 2004–2008 varied by a factor of 1 to 1.25 across regions. The reasons for these variations are unclear. PMSI data are useful for the epidemiological surveillance of this cancer, particularly for studies of geographic variations. (R.A.)
