51 The indicator breast-contour-preserving procedure Figure 2. Multiple treatment modalities of the parameter breast-contour-preserving procedure (BCPP) for patients diagnosed with breast cancer separated by age. Variation between hospitals The proportion of patients undergoing BCPP varied extensively between individual hospitals, and this range of BCPP (47–88%) was wider than the observed variation of BCS (37–67%). All three treatment strategies constituting BCPP showed a wide variation between hospitals ( Table 2 ). There was an inverse relationship between the proportion of primary BCS and the other two strategies to preserve the breast contour per hospital ( Figure 3 ). The rates of BCS after NAC and mastectomy combined with IBR varied largely between hospitals: some hospitals never used BCS after NAC nor mastectomy with IBR, while other institutions performed BCS after NAC in up to 21% and IBR in up to 28% of patients. Hospital volume did not influence the institutional BCPP rate (data not shown). <30 30-39 40-49 50-59 60-69 ≥70 Age Mastectomy with immediate reconstruction Breast conserving surgery and neo-adjuvant chemotherapy Primary breast conserving surgery 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% 3
