NOTE. Population includes 15,006 men diagnosed with testicular nonseminoma as a first primary cancer (International Classification of Diseases for Oncology, Third Edition, codes 9065, 9070 to 9073, 9080 to 9085, and 9100 to 9102) initially managed with chemotherapy (n = 6,909) or surgical approaches alone (n = 8,097). The sparse number of patients with testicular nonseminoma who were given RT (n = 99) precluded further evaluation.
Abbreviations: NOS, not otherwise specified; RT, radiotherapy.
The Surveillance, Epidemiology, and End Results (SEER) program collects data with regard to general categories of initial treatment (eg, chemotherapy, radiation, surgery) but does not include any details or any data on subsequent therapy. Surgical procedures defined as initial by the SEER program are those that are part of the original treatment plan at diagnosis.
Attained age was defined as the age of the patient at the time of death or end of follow-up.
County education level was categorized based on tertiles of distribution, as follows: education 1 represents the lowest level (composed of counties with ≥ 25% of men without a high school education); education 2 represents the medium level (counties with 15% to < 25% of men without a high school education); and education 3 represents the highest level (counties with < 15% of men without a high school education).
The median ages at testicular cancer diagnosis of patients who were never married, married, and separated/divorced/widowed are 24.5, 33.2, and 36.3 years, respectively.
Includes one patient whose marital status was described as unmarried/domestic partner.
