Higher levels of a certain type of immune cell may explain why immunotherapy for prostate cancer is more effective in Black men than in white men, researchers say.
The finding could lead to immunotherapy-based precision treatment for localized aggressive and advanced prostate cancer in all races.
For the study, the researchers analyzed 1,300 prostate tumor samples and found that, on average, those from Black men had higher levels of plasma cells (a type of immune cell) than those from white men.
