Years of life lost in squamous cell carcinoma of the penis.

INTRODUCTION

Survival patterns in squamous cell carcinoma of the penis (SCCP) have been described in several studies. However, the years of life lost (YLL) among patients with SCCP compared to the general population have not been quantified.

METHODS

Within the SEER database (2004-2021), SCCP patients aged 40-75 years were included. SCCP patients were stratified according to stage at diagnosis in localized (T1-2, N0, M0), regional (T3-4, anyN, M0; anyT, N +, M0), and metastatic (anyT, anyN, M1). For each patient, an age- and sex-mathced control was generated from Social Security Administration life tables using Monte Carlo simulation. Subsequently, the average YLL until the age of 75 years between SEER patient cases and simulated controls were quantified using the Kaplan-Meier methodology.

RESULTS

Overall, 1666 (64.9%) localized, 505 (28.1%) regional and 123 (7.0%) metastatic SCCP patients were included. Relative to population controls, SCCP patients of all-stages exhibited 4.4 YLL (p < 0.001). In subsequent stage stratified analyses YLL values were 3.0 vs. 6.0 vs. 10.7 YLL (p < 0.001) for respectively localized, regional and metastatic SCCP subgroups.

CONCLUSION

In general SCCP patients are at 4.4 YLL relative to population controls, the latter may reach 10.7 YLL when metastatic stage at presentation is diagnosed.
