Background: It is unknown whether married status may be associated with lower cancer-specific mortality (CSM) rates in primary urethral carcinoma (PUC) patients. To test for differences in CSM rates, according to marital status, we relied on the Surveillance, Epidemiology, and End Results (SEER) database 2000-2020. Methods: Patient (age, sex, race/ethnicity, marital status), tumor (stage, histology), and treatment (surgery, systemic therapy) characteristics of PUC patients were tabulated. Then, Kaplan-Meier plots, as well as univariable and multivariable Cox regression (MCR) models tested for differences in CSM rates according to marital status in overall cohort and then in sex-specific subgroup analyses. Results: Of all 1,571 PUC patients, 70% were male vs. 30% female. Females were statistically significantly younger (68 vs. 73 years), more frequently unmarried (54 vs. 28%), non-Caucasian (43 vs. 24%), more frequently harbored T3-4N0M0 (39 vs. 18%) and less frequently T1-2N0M0 (53 vs. 69%) or TanyN1-2M0/TanyNanyM1 (8 vs. 13%), relative to males. Moreover, we recorded differences in histotype proportions in females vs. males (urothelial 30 vs. 64%; squamous 24 vs. 22%; adenocarcinoma 36 vs. 7%; others 10 vs. 6%) and surgical treatment (none 22 vs. 17%; excisional biopsy 22 vs. 36%; partial urethrectomy 14 vs. 16%; radical urethrectomy 42 vs. 31%). In MCR models focusing on the entire cohort, married status independently predicted lower CSM (hazard ratio [HR]:0.82; P = 0.02). Similarly, in MCR models focusing on females, married status independently predicted lower CSM (HR:0.73; P = 0.03). Conversely, in MCR models focusing on males, married status failed to independently predict lower CSM (HR:0.89; P = 0.3). Conclusions: Married status was associated with lower CSM in PUC patients. However, this benefit applies to female PUC patients, but not to their male counterparts.

Abstract
Background: It is unknown whether married status may be associated with lower cancer-specific mortality (CSM) rates in primary urethral carcinoma (PUC) patients. To test for differences in CSM rates, according to marital status, we relied on the Surveillance, Epidemiology, and End Results (SEER) database 2000-2020. Methods: Patient (age, sex, race/ethnicity, marital status), tumor (stage, histology), and treatment (surgery, systemic therapy) characteristics of PUC patients were tabulated. Then, Kaplan-Meier plots, as well as univariable and multivariable Cox regression (MCR) models tested for differences in CSM rates according to marital status in overall cohort and then in sex-specific subgroup analyses. Results: Of all 1,571 PUC patients, 70% were male vs. 30% female. Females were statistically significantly younger (68 vs. 73 years), more frequently unmarried (54 vs. 28%), non-Caucasian (43 vs. 24%), more frequently harbored T3-4N0M0 (39 vs. 18%) and less frequently T1-2N0M0 (53 vs. 69%) or TanyN1-2M0/TanyNanyM1 (8 vs. 13%), relative to males. Moreover, we recorded differences in histotype proportions in females vs. males (urothelial 30 vs. 64%; squamous 24 vs. 22%; adenocarcinoma 36 vs. 7%; others 10 vs. 6%) and surgical treatment (none 22 vs. 17%; excisional biopsy 22 vs. 36%; partial urethrectomy 14 vs. 16%; radical urethrectomy 42 vs. 31%). In MCR models focusing on the entire cohort, married status independently predicted lower CSM (hazard ratio [HR]:0.82; P = 0.02). Similarly, in MCR models focusing on females, married status independently predicted lower CSM (HR:0.73; P = 0.03). Conversely, in MCR models focusing on males, married status failed to independently predict lower CSM (HR:0.89; P = 0.3). Conclusions: Married status was associated with lower CSM in PUC patients.
