To further investigate the independent relationship of CCAT2 with prognosis for the LNP patients that had received adjuvant CMF, we have extended our previous patient group [12] with 13 new patients, which included 5 new LNP primary BC patients which received systemic adjuvant CMF, and reanalyzed the data based on the most updated clinical information available for these patients. Here, CCAT2 is linked to breast cancer.
