SPACA6 and breast cancer: Furthermore, in the analysis of Progression-Free Interval (PFI), we observed that BC patients with high SPACA6P-AS expression had a shorter PFI, with a HR of 1.40 (95% CI 1.01–1.94) and a p-value of 0.043 (Fig. 4D-F), indicating a higher risk of recurrence or disease progression for these patients.
