Abstract

Background This article reports on the experience with penile squamous cell carcinoma (PSCC) in a unique multiethnic patient population from Los Angeles, California, with regard to treatments rendered and clinical outcomes. Patients and Methods Available clinical, pathologic, and treatment information for PSCC patients treated at 3 hospitals associated with the University of Southern California from 1991 to 2011 was retrospectively reviewed. Associations of patient variables with prognosis were assessed using univariable and multivariable analyses. Results Of the 95 PSCC patients identified, clinicopathologic and outcome information was available on 89 men (median age, 53 years; median follow-up, 23 months). National minorities comprised 76.4% of the cohort with 57.3% Hispanics accounting for all patients. Presence of poorly differentiated tumors was associated with higher tumor stage (P =.020), nodal metastasis (P =.016), distant metastasis (P =.004), and advanced AJCC disease stage (P =.001). Univariate analysis showed that tumor (P =.008), nodal (P =.033), and metastasis (P <.001) stage, and tumor differentiation (P =.010) were associated with survival. When categorized according to the AJCC classification, patients with ≥ stage III disease had worse outcomes (P =.006). Type of primary therapy delivered did not affect outcomes. AJCC disease stage was independently prognostic in multivariable analysis (P =.035). Conclusion These results confirm associations of several clinicopathologic factors with PSCC outcomes, although the presented population differs from others previously described from the United States with a relatively higher proportion of Hispanic men. This highlights the need for studies on the effects of race, cultural, health, and behavioral patterns on PSCC outcomes in multiethnic populations.
