Prostate cancer genetic alterations in Hispanic men

Area of Science:

• Oncology
• Genetics
• Genomics

Background:

• Prostate cancer DNA alterations vary by ethnicity.
• Previous studies focused on White, Black, and Asian men.
• This study examines DNA alterations in Hispanic men with prostate cancer.

Purpose of the Study:

• To investigate DNA alteration frequencies in primary and metastatic prostate cancer in self-reported Hispanic men.
• To compare these frequencies with non-Hispanic White men.
• To identify potential therapeutic targets based on genetic profiles.

Main Methods:

• Utilized targeted next-generation sequencing data from prostate cancer tissues.
• Analyzed genomic profiles from Memorial Sloan Kettering Cancer Center samples.
• Employed Fisher's exact test for ethnic and racial category comparisons.

Main Results:

• TMPRSS2 and ERG alterations were less common in non-Hispanic White men with primary tumors.
• KRAS and CCNE1 alterations were less prevalent in non-Hispanic White men with metastatic tumors.
• No significant differences were observed in actionable alterations or androgen receptor mutations between groups.

Conclusions:

• DNA alteration frequencies in prostate cancer differ between Hispanic-White and non-Hispanic White men.
• Actionable genetic alterations were similarly prevalent, suggesting therapeutic potential.
• Further research is needed to correlate findings with clinical characteristics and genetic ancestry.
