Hazard ratios

CA IX positive (n = 151)

CA IX negative (n = 794)

Overall mortality

0.87 (0.60–1.27)

0.82 (0.69–0.97)

Disease-specific mortality

0.83 (0.55–1.27)

0.76 (0.63–0.93)

Distant metastases

0.83 (0.54–1.25)

0.76 (0.63–0.91)

Locoregional recurrence

0.23 (0.08–0.61)

0.16 (0.09–0.28)

Presented are hazard ratios (95% confidence intervals) of overall mortality, disease-specific mortality, distant metastases and loco-regional recurrence probabilities after postmastectomy radiotherapy in carbonic anhydrase (CA) IX positive and in CA IX negative high-risk breast cancer patients.
