Objective: Axillary ultrasound (US) is often part of the routine assessment of the clinically negative axilla in primary breast cancer, which determines the extent of axillary surgery to be performed. This study aims to ascertain the burden of disease in the axilla of patients with a normal clinical examination (cN0) but with US detected metastatic axillary lymph nodes.
Materials and methods: We retrospectively identified 345 female patients who underwent axillary lymph node dissection, following a positive lymph node biopsy, between January 2015 and August 2019.Eighty-nine of those had a positive biopsy prior to surgery. They were divided into two groups: Those with clinically palpable axillary disease preoperatively, cN1 (n = 41), and those with a normal clinical axillary examination, cN0 (n = 48). We assessed the number of positive axillary lymph nodes dissected in the two groups.
Results: In the cN0 group the mean value of excised disease-positive axillary lymph nodes was 3.6, while in the cN1 group it was 8.0 (p<0.01). However, further analysis showed that 25 patients of the cN0 who had T1/T2 tumors had ≥3 positive lymph nodes.
Conclusion: Our study suggests that the presence of clinically palpable axillary lymph nodes appears to be correlated to a higher number of positive lymph nodes. However, in cases of non-palpable sonographically positive lymph nodes there might still be significant axillary disease, even in T1 and T2 tumors. Therefore we still support the routine use of preoperative sonographic assessment of the axilla for early breast cancer.
Objective: Oncoplastic reconstruction (OR) enables widening of the indications for breast conserving therapy (BCT) and is redefining the limits of breast conservation. We examined the outcome and satisfaction of patients undergoing OR after radical lumpectomy (excision of more than 25% of the breast volume) and compared it to the outcome of women undergoing OR after standard lumpectomy.
Materials and methods: A retrospective, cohort study, including all patients undergoing OR after BCT between 2009 and 2018, was conducted. The ratio of volume of excision to breast volume was calculated using imaging studies. The study group included women that had more than 25% of their breast volume removed. The remainder formed the control group. Demographic characteristics, oncological treatment, and operation properties were collected. We compared post-operative complications, margin status and need for further surgery, as well as patient satisfaction, evaluated using the BREAST-Q Questionnaire.
Results: One hundred and fifty women were included, of whom 24 (16%) comprised the study group with a mean breast volume reduction of 39%, while the remainder (mean volume reduction 8%) served as controls. Patient, tumor characteristics and treatment were comparable. There was a non-significant higher proportion of women in the radical group that underwent a second operation due to complications or positive margins [4/24 (16.7%) vs. 14/126 (11%), p = 0.4). Physical well-being was similar but satisfaction with breasts and with outcome was slightly lower for the study group. These differences did not reach statistical significance.
Conclusion: Surgical outcome and patient satisfaction in women undergoing very extensive breast resections with OR are comparable to standard resections.
