Survival outcomes of testicular cancer (TC) in Hispanic men based on analyses from the National Cancer Database (NCDB).

Abstract

622 Background: The incidence of TC among Hispanic men has been rising, as reported in our analysis of patients in the United States (Yu et al., JCO 2024 42 (4):503). We sought to determine the survival outcomes in Hispanic men based on data obtained from the National Cancer Database (NCDB). Methods: We extracted patient-level data from the NCDB and identified the incidence, demographics, treatment patterns, and outcomes in Hispanic men with TC diagnoses (non-seminoma, NS; seminoma, S) from 2004 to 2020. Results: There were a total of 89550 patients (pts) in the database. Median age at diagnosis was 37 years and 29 years for S and NS pts, respectively. There were 11005 (12.3%) TC pts designated as Hispanic (H), of whom 5396 and 5609 had S and NS TCs, respectively. In contrast, there were a total number of 74350 non-Hispanic (NH) patients with TC; n = 43629 with S, n = 30721 with NS. The majority of H pts had a Charlson-Deyo score of 0 (94.2%). Less than half of H pts had private insurance (48.8%) compared to three-quarters of NH patients (75.1%). 19.6% of H pts were diagnosed with stage II & III TC (compared to 15.8% in NH pts). Pts were treated at academic/research centers in 6.6% of H pts versus 10.8% in NH pts. For S pts, radiation was utilized in 19.4% of H pts vs 25.8% in NH pts, chemotherapy utilized in 28.3% H pts vs 24.4% in NH pts, whereas chemotherapy for NS pts was utilized in 60.1% in H pts vs 53.4% in NH pts. Overall Survival (OS) was not significantly different in S pts for H pts vs NH pts (Log-rank p = 0.066), but among NS pts, H patients did worse compared to NH pts (Log-rank p < 0.001) although OS differences were seen in pooled analyses of S and NS pts (log-rank p < 0.001). Conclusions: Our analysis reports on the treatment patterns and survival of Hispanic men with TC. Survival appears to be worse for Hispanic patients with non-seminoma compared to non-Hispanic patients, but outcomes for seminoma are similar. We also noted slight differences in patterns of treatment receipt for seminoma versus non-seminoma in Hispanic men which may have to do with stage at diagnosis and access to care.
