Atypical ductal hyperplasia and the risk of underestimation: tissue sampling method, multifocality, and associated calcification significantly influence the diagnostic upgrade rate based on subsequent surgical specimens.

Background: Risk assessment and therapeutic options are challenges when counselling patients with an atypical ductal hyperplasia (ADH) to undergo either open surgery or follow-up only.

Methods: We retrospectively analyzed a series of ADH lesions and assessed whether the morphological parameters of the biopsy materials indicated whether the patient should undergo surgery. A total of 207 breast biopsies [56 core needle biopsies (CNBs) and 151 vacuum-assisted biopsies (VABs)] histologically diagnosed as ADH were analyzed retrospectively, together with subsequently obtained surgical specimens.

Second International Consensus Conference on lesions of uncertain malignant potential in the breast (B3 lesions).

Purpose: The second International Consensus Conference on B3 lesions was held in Zurich, Switzerland, in March 2018, organized by the International Breast Ultrasound School to re-evaluate the consensus recommendations.

Methods: This study (1) evaluated how management recommendations of the first Zurich Consensus Conference of 2016 on B3 lesions had influenced daily practice and (2) reviewed current literature towards recommendations to biopsy.

Results: In 2018, the consensus recommendations for management of B3 lesions remained almost unchanged: For flat epithelial atypia (FEA), classical lobular neoplasia (LN), papillary lesions (PL) and radial scars (RS) diagnosed on core-needle biopsy (CNB) or vacuum-assisted biopsy (VAB), excision by VAB in preference to open surgery, and for atypical ductal hyperplasia (ADH) and phyllodes tumors (PT) diagnosed at VAB or CNB, first-line open surgical excision (OE) with follow-up surveillance imaging for 5 years.

First International Consensus Conference on lesions of uncertain malignant potential in the breast (B3 lesions).

The purpose of this study is to obtain a consensus for the therapy of B3 lesions. The first International Consensus Conference on lesions of uncertain malignant potential in the breast (B3 lesions) including atypical ductal hyperplasia (ADH), flat epithelial atypia (FEA), classical lobular neoplasia (LN), papillary lesions (PL), benign phyllodes tumors (PT), and radial scars (RS) took place in January 2016 in Zurich, Switzerland organized by the International Breast Ultrasound School and the Swiss Minimally Invasive Breast Biopsy group-a subgroup of the Swiss Society of Senology. Consensus recommendations for the management and follow-up surveillance of these B3 lesions were developed and areas of research priorities were identified.

Papillary lesions of the breast: outcomes of 156 patients managed without excisional biopsy.

Papillomas of the breast are benign epithelial neoplasms. Because of the low, but continued potential for malignancy, the treatment options after initial diagnosis remain controversial. The aim of this study was to analyze the clinical course of patients with papilloma who were managed by active surveillance following initial diagnosis by core needle biopsy or vacuum-assisted biopsy.

Fluctuating mastectomy rates across time and geography.

In 2009, 2 single-institution studies from the United States reported increasing mastectomy rates during the last decade. We have recently reported unilateral mastectomy trends from a European database and demonstrated a significant trend of decreasing mastectomy rates from 38.1 % in 2005 to 13.

Mastectomy trends for early-stage breast cancer: a report from the EUSOMA multi-institutional European database.

Introduction: Recent single-institution reports have shown increased mastectomy rates during the last decade. Further studies aiming to determine if these reports could be reflecting a national trend in the United States of America (US) have shown conflicting results. We report these trends from a multi-institutional European database.

Intramammarian flap reconstruction (IFR) technique in breast conserving surgery.

As large segmentectomies often lead to asymmetries and indentations in the breast, numerous oncoplastic reconstruction methods have been published over the past years. Many of these involve additional skin incisions, resulting in more and larger scars.This article presents a method, which uses the same incision as for the segmentectomy and does not lead to additional scars.

[Sentinel lymphonodectomy in breast cancer - our own experience. Part 2].

Unlabelled: The aim of this investigation was to document the personal learning curve of the sentinel lymphonodectomy in breast surgery and to compare it with the experiences of other authors.

Results: Between July 1999 and May 2004, the authors performed 218 sentinel lymphonodectomies, 48 of them during the 24-month evaluation period with consecutive full axillary dissection. The overall detection rate was 212/218 or 97.

[Sentinel lymphonodectomy -- new surgical standard for the evaluation of the axilla:an overview. Part 1].

Complete axillary dissection is still integral component of breast cancer treatment, but significant morbidity is associated with this procedure. Sentinel lymphonodectomy can replace complete axillary dissection in selected cases and can significantly reduce morbidity. Sentinel lymphonodectomy has become a new surgical standard and should be offered to all patients with unicentric tumors of less than 3 cm in diameter.
