Fig. 8. CDK12 overexpression is a prognostic and therapeutic biomarker in breast cancer patients and predicts response to antimetabolite therapy targeting the SGOC network.

a Pearson correlation coefficient analysis of the METABRIC breast cancer patient cohort showing positive correlation of a SGOC network gene signature (SGOCCDK12 average z-score) with CDK12 transcript levels (CDK12 z-score) in all breast cancers and in the indicated molecular subtypes. Derivation of the SGOCCDK12 signature is described in Supplementary Fig. 4. The number of patients in each group is indicated. R, correlation coefficient value; P, P-value. Padj, FDR adjusted P value for the 3 subgroups tested. b Cumulative incidence of distant metastasis in CDK12HIGH, CDK12LOW and CDK12NULL HER2-negative (HER2-neg) breast cancer patients in response to chemotherapy (CT) with taxane/anthracycline (Tax/AC)- vs. methotrexate-based (CMF, cyclophosphamide, MTX, fluorouracil). The 10-year cumulative distant metastasis rate (%) and the patient number of each class are indicated. HR, multivariable hazard ratio adjusted for standard clinical parameters (see Methods). P, P-value, stratified Wald test. c Cumulative distant metastasis in CDK12HIGH and CDK12LOW hormone-negative, lymph node-positive patients randomized to metronomic cyclophosphamide+methotrexate (CM) chemotherapy vs. no chemotherapy (control, Ctr). Patients no.: CDK12HIGH = 31, CDK12LOW = 73 in the control group; CDK12HIGH = 35, CDK12LOW = 74 in the CM therapy group. HR, hazard ratio (see also Supplementary Fig. 5c for cohort description and multivariable analyses). P, P-value, stratified likelihood-ratio test. d Cumulative incidence of deaths in CDK12HIGH vs. CDK12LOW neoadjuvant triple-negative breast cancer (TNBC) patients treated with second-line CMF after failure of first-line Tax/AC chemotherapy. HR, multivariable hazard ratio for CDK12HIGH vs. CDK12LOW patients. The 10-year cumulative death rate (%) for each category is indicated. Patient no., CDK12HIGH = 82, CDK12LOW = 43, see also Supplementary Fig. 5e). HR, multivariable hazard ratio; P, P-value, stratified Wald test. Source data are provided as Source Data file.
