Preoperative Localization and Surgical Margins in Conservative Breast Surgery

Breast-conserving surgery (BCS) is the treatment of choice for early breast cancer. The adequacy of surgical margins (SM) is a crucial issue for adjusting the volume of excision and for avoiding local recurrences, although the precise definition of an adequate margins width remains controversial. Moreover, other factors such as the biological behaviour of the tumor and subsequent proper systemic therapies may influence the local recurrence rate (LRR). However, a successful BCS requires preoperative localization techniques or margin assessment techniques. Carbon marking, wire-guided, biopsy clips, radio-guided, ultrasound-guided, frozen section analysis, imprint cytology, and cavity shave margins are commonly used, but from the literature review, no single technique proved to be better among the various ones. Thus, an association of two or more methods could result in a decrease in rates of involved margins. Each institute should adopt its most congenial techniques, based on the senologic equipe experience, skills, and technologies.

Bowel ultrasound in Crohn’s disease: surgical perspective

BackgroundBowel ultrasound has been proven to be a useful tool in the management of Crohn’s disease, particularly in the assessment of intra-abdominal complications, most of which require surgery.Materials and methodsThe National Library of Medicine has been searched for articles on the use of bowel ultrasound in Crohn’s disease focusing on aspects of interest to the surgeon.Results and conclusionsSeveral studies have demonstrated that bowel ultrasound may be useful to reduce the risk of unnecessary laparotomy in patients presenting acute abdomen with suspected chronic inflammatory bowel disease. Bowel ultrasound has been proven to be of value in the follow-up of Crohn’s disease patients since allowing early diagnosis of intra-abdominal complications and, therefore, optimising the diagnostic and surgical approach. At follow-up, bowel ultrasound may accurately diagnose early post-operative complications and long-term disease recurrence. In patients submitted to conservative surgery, ultrasonography reveals changes in diseased bowel walls that may be predictive of recurrence of the disease, and hence determinant in the choice of medical treatment.

Localization of nonpalpable breast lesions with sonographically visible clip: optimizing tailored resection and clear margins

BACKGROUND Achieving clear margins with adequate resection volumes is one of the principal goals of breast-conserving surgery. The aim of our study was to compare preoperative localization using 2 different clips, radiopaque or sonographically visible, to reach this goal. METHODS We reviewed 209 consecutive nonpalpable breast cancers that were treated with lumpectomy: 59 with radiopaque and 150 with sonographically visible clip positioned during biopsy procedure. In the former case, preoperative localization was performed with mammography and in the latter by ultrasonography. RESULTS Clear margins were achieved in 80.4% of patients: 57.6% in the first and 89.3% in the second group (P < .0001; odds ratio, 7.6; 95% confidence interval, 3.4 to 17.2). By using sonographically visible clips, the re-excision rate has decreased from 42.4% to 10.7%, (P < .0001), and resections resulted smaller with average calculated resection ratio of 3.54 vs. 5.08 (P = .03). CONCLUSIONS Preoperative localization using a sonographically visible clip allows a more tailored breast-conserving surgery and reduces the re-excision rate.

Is there a role for homeopathy in breast cancer surgery? A first randomized clinical trial on treatment with Arnica montana to reduce postoperative seroma and bleeding in patients undergoing total mastectomy -

Aim: This study aimed to evaluate the benefits of Arnica montana on post-operative blood loss and seroma production in women undergoing unilateral total mastectomy by administering Arnica Montana 1000 Korsakovian dilution (1000 K). Materials and Methods: From 2012 to 2014, 53 women were randomly assigned to A. montana or placebo and were followed up for 5 days. The main end point was the reduction in blood and serum volumes collected in drainages. Secondary end points were duration of drainage, a self-evaluation of pain, and the presence of bruising or hematomas. Results: The per-protocol analysis revealed a lower mean volume of blood and serum collected in drainages with A. montana (−94.40 ml; 95% confidence interval [CI]: 22.48-211.28; P = 0.11). A regression model including treatment, volume collected in the drainage on the day of surgery, and patient weight showed a statistically significant difference in favor of A. montana (−106.28 ml; 95% CI: 9.45-203.11; P = 0.03). Volumes collected on the day of surgery and the following days were significantly lower with A. montana at days 2 (P = 0.033) and 3 (P = 0.0223). Secondary end points have not revealed significant differences. Conclusions: A. montana 1000 K could reduce post-operative blood and seroma collection in women undergoing unilateral total mastectomy. Larger studies are needed with different dilutions of A. montana to further validate these data.

Primary Carcinoma of Ectopic Breast Tissue

We describe a case of a 37-year-old woman with a left axillary mass. Often, the initial differential diagnosis of an axillary mass is not easy to make. We performed fine-needle aspiration of the axillary mass that revealed the presence of numerous epithelial neoplastic cells. A bilateral digital mammography, chest and abdomen computed tomography scan, and a magnetic resonance imaging scan (MRI) of the axillary region were performed. In our case, the MRI was able to exclude the presence of neoplastic tissue in the breast; moreover, it confirmed the presence of metastatic lymph nodes and recognized a second type of nodular lesion in the axilla, showing on the MRI a radiologic pattern similar to breast tissue.

Usefulness of Preoperative Diagnosis with Magnetic Resonance Imaging for Conservative Surgery in Paget's Disease of the Breast

Background: Paget’s disease (PD) of the breast is a relatively rare condition (incidence 1–3%) among primary breast cancers [6]. It presents with suggestive symptoms like erythema, nipple bleeding and ulceration. Patient and Methods: A 76-year-old woman was followed up for cancer of the left breast that had been operated 10 years before. During her annual check, a lesion suggestive of PD was detected. Mammography and ultrasound were performed, without evidence of a new breast lesion. In consideration of a possible underestimation of the real extent of the disease, we performed magnetic resonance imaging (MRI). Results: MRI showed an irregularly shaped tissue infiltrating the external side of the right breast. The pathologically bright signal involved the nipple and deformed the areolar skin. The characteristics of the increased signal were typical of a hypervascular invasive pattern and for tumoral neoangiogenesis. We performed a mastectomy with sentinel lymph node (SLN) biopsy, with evidence of a DIN 3 carcinoma associated with PD of the nipple at the final pathology report. Conclusion: The MRI was instrumental for the assessment of the existence and extent of malignant disease in a patient with PD but without a palpable lesion detectable with negative ultrasound and mammography

Sentinel node biopsy in ductal carcinoma in situ of the breast: Never justified?

Sentinel lymph node biopsy for ductal carcinoma in situ (DCIS) of the breast is not standard of care. However, nodal involvement for DCIS patients is reported. Aim of our study was to identify preoperative features predictive of nodal involvement in DCIS patients. We have retrospectively reviewed 175 patients with a preoperative diagnosis of DCIS following a vacuum‐assisted breast biopsy, and undergoing surgery with sentinel node biopsy. Variables distribution was compared between patients upstaged to invasive cancer at final pathology and patients with a confirmed DCIS, and between positive vs negative sentinel node patients. Univariate and multivariate analyses were performed for risk of a positive node. Lymph node biopsy was positive in 13 (7.4%) patients, with 8 (61.5%) macrometastases and 5 (38.5%) micrometastases. In these patients, Breast Imaging Reporting and Data System (BI‐RADS) index >4 (OR 4.69, 95% CI 1.282‐17.224, P = .02), lesion extension ≥20 mm (OR 4.25, 95% CI 1.255‐14.447, P = .02), multifocal disease (OR 4.12, 95% CI 0.987‐17.174, P = .05), comedo type (OR 3.54, 95% CI 1.044‐11.969, P = .04), and upstaging (OR 4.56, 95% CI 1.080‐19.249, P = .04) were all predictive of nodal involvement, although upstaging could not be predicted preoperatively. By multivariate analysis, the only independent factor predictive for positive sentinel node was multifocal disease (OR 5.14, 95% CI 1.015‐26.066, P < .05). A preoperative diagnosis of DCIS, also including advanced biopsy systems such as vacuum‐assisted breast biopsy, may be not always sufficient to exclude patients from sentinel node biopsy. DCIS patients with associated BI‐RADS >4, lesion extension ≥20 mm, comedo type, and above all multifocal disease should be considered for axillary evaluation.
