Aim: To identify predictors for infiltrating carcinoma and lymph node involvement, before immediate breast reconstructive surgery, in patients with an initial diagnosis of extensive pure ductal carcinoma in situ of the breast (DCIS)., Patients and Methods: Between January 2000 and December 2009, 241 patients with pure extensive DCIS in preoperative biopsy had underwent mastectomy. Axillary staging (sentinel node and/or axillary dissection) was performed in 92% (n = 221) of patients. Patients with micro-invasive lesions at initial diagnosis, recurrence or contralateral breast cancer were excluded., Results: Respectively 14% and 21% of patients had a final diagnosis of micro-invasive carcinoma (MIC) and invasive ductal carcinoma (IDC). Univariate analysis showed that the following variables at diagnosis were significantly correlated with the presence of either MIC or IDC in the mastectomy specimen: palpable tumor (p = 0.002), high grade DCIS (p = 0.002) and detection of an opacity by mammography (p = 0.019). Axillary lymph node (ALN) involvement was reported in 9% of patients. Univariate analysis suggested that a body mass index higher than 25 (p = 0.007), a palpable tumor (p = 0.012) and the detection of an opacity by mammography (p = 0.044) were associated with an increased rate of ALN involvement., Conclusion: Skin-sparing mastectomy and immediate breast reconstruction (IBRS) has become increasingly popular, especially for patients with extended DCIS of the breast. This study confirmed that extended DCIS is associated with a substantial risk of finding MIC or IDC on the surgical specimen but also ALN involvement. Adjuvant systemic treatment and/or radiotherapy could be indicated for some of these patients after the surgery. Patients should be informed of the rate of 1) complications associated to IBRS that will potentially delay the introduction of systemic or local therapy 2) complications associated to radiotherapy after IBRS., (Copyright © 2014 The Authors.

Purpose: To assess the efficacy of exclusive hypo-fractionated radiotherapy (HFRT) without previous breast-conserving surgery (BCS) in elderly women., Materials and Methods: From 1995 to 1999, we have treated with breast-conserving treatment 396 patients older than 70 years with early-stage breast cancer (T1,T2 tumours) at the Institut Curie, Paris, France. Seventy-nine consecutive elderly non-metastatic patients treated for early breast cancer have been treated with HFRT. Of them, 50 underwent BCS followed by HFRT of 32.5 Gy/5 fractions/5 weeks, and 29 patients (presented with different co-morbidities, inoperable or patients' refusal, and/or transportation problems) received the same HFRT schedule followed by a 13 Gy boost (two fractions of 6.5 Gy) as exclusive radiotherapy treatment. This population of 29 patients has been studied. In case of hormonal positive status, hormonal therapy was also proposed to the patients., Results: There was a median follow-up of 93 months (9-140 months). At 7-year follow-up, the cause-specific survival was 96.4% (confidence interval (CI) 95: 89.8.6-100%), the metastasis-free survival rate was 92.4% (CI 95: 82.8-100%) and the loco-regional control rate was 95.8% (CI 95: 88.2-100%)., Conclusions: This long-term follow-up retrospective study demonstrated acceptable local control and good outcome in elderly patients treated by exclusive HFRT for early breast cancer. However, large-scale prospective randomised trials are needed to confirm these results., (Copyright © 2010 Elsevier Ltd. All rights reserved.)
