Kaplan–Meier curves showing that high expression of COL11A1 within the surrounding stromal fibroblast is associated with ipsilateral local recurrence-free interval in the whole series either for all recurrences (a) or invasive recurrences (b), in breast conserving surgery without adjuvant radiotherapy (c: all recurrences and d: invasive recurrences) and in patients treated with breast conserving surgery followed by adjuvant radiotherapy (e: all recurrences and f: invasive recurrences)
