Phospho-p90RSK expression and response to neoadjuvant chemotherapy. In 112 locally advanced breast cancer patients, the expression of phospho-p90RSK expression and the radiologic tumor size shrinkage were examined. Pre-chemotherapy radiologic tumor size and postchemotherapy tumor size (a), proportional tumor size reduction, and post-chemotherapy pathologic tumor size (b) were examined in all tumors (left panel), estrogen receptor-positive tumors (middle panel), and estrogen receptor-negative tumors (right panel). * denotes for p < 0.05 from Student’s t-test.
