NR4A1 and breast carcinoma: Another study investigating associations between a panel of free oxysterols and breast cancer outcomes in 58 breast cancer patients reported an association between higher levels of free THC and poorer disease-free survival (p = 0.037, effect estimate not reported), while no significant associations were observed for other oxysterols including 7a-HC, 7-KC, 5a6a-EC, and 5b6b-EC [19]; we observed no associations between these oxysterols and outcomes with the exception of an association between THC and recurrence in participants with hormone-receptor negative disease.
