SOCS1 and breast cancer: After a median follow up of 10 years, we found SOCS1 mRNA expression levels to be higher among women who remained disease free compared to those who developed local recurrence [mean copy number 48 vs. 1.2, 95% CI (13, 81.2), p = 0.0073], and compared to those who died from breast cancer [mean copy number 48 vs. 7.4, 95% CI (6, 75.6), p = 0.021].
