Retrospective, Multicenter Analysis Comparing Conventional with Oncoplastic Breast Conserving Surgery: Oncological and Surgical Outcomes in Women with High-Risk Breast Cancer from the OPBC-01/iTOP2 Study.

Introduction: Recent data suggest that margins ≥2 mm after breast-conserving surgery may improve local control in invasive breast cancer (BC). By allowing large resection volumes, oncoplastic breast-conserving surgery (OBCII; Clough level II/Tübingen 5-6) may achieve better local control than conventional breast conserving surgery (BCS; Tübingen 1-2) or oncoplastic breast conservation with low resection volumes (OBCI; Clough level I/Tübingen 3-4).

Methods: Data from consecutive high-risk BC patients treated in 15 centers from the Oncoplastic Breast Consortium (OPBC) network, between January 2010 and December 2013, were retrospectively reviewed.

Accelerated partial breast irradiation with 3-dimensional conformal and image-guided intensity-modulated radiotherapy following breast conserving surgery - 7-Year results of a phase II trial.

Purpose: To present the 7-year results of accelerated partial breast irradiation (APBI) using three-dimensional conformal (3D-CRT) and image-guided intensity-modulated radiotherapy (IG-IMRT) following breast-conserving surgery (BCS).

Patients And Methods: Between 2006 and 2014, 104 patients were treated with APBI given by means of 3D-CRT using 3-5 non-coplanar, isocentric wedged fields, or IG-IMRT using kV-CBCT. The total dose of APBI was 36.

[Assessing the needs of Hungarian breast cancer patients for modern oncoplastic breast surgical treatment. Questionnaire study of 500 patients].

Introduction: The significant need for breast reconstruction resulting from the spread of oncoplastic breast surgery raises a number of systemic issues. Clarification and regulation of the indications are needed for aesthetic changes of the reconstructed breast due to oncotherapy treatments, ageing and technical problems of implants; a number of operations, targeted aesthetic goals as well as surgical capacities and financial background should also be determined.

Aim: Our aim was to conduct a survey on the opinions and needs of the Hungarian breast cancer population about a modern breast reconstruction system.

Implementation of Stereotactic Accelerated Partial Breast Irradiation Using Cyber-Knife - Technical Considerations and Early Experiences of a Phase II Clinical Study.

To report the implementation, dosimetric results of and early experiences with stereotactic accelerated partial breast irradiation (SAPBI) following breast conserving surgery (BCS) for postmenopausal low-risk St I-II invasive breast cancer (IBC) patients. Between November 2018 and August 2019, 27 patients were registered in our phase II prospective study. SAPBI was performed with Cyber-Knife (CK) M6 machine, in 4 daily fractions of 6.

[Evaluation of the modified Regnault “B” technique as a standard level II oncoplastic breast-conserving surgery].

Introduction And Aim: This study aimed to describe the modified Regnault "B" oncoplastic technique as a standard volume-displacement level II oncoplastic breast-conserving surgery and the related clinicopathological study.

Method: A retrospective, single-centre study was performed between April 2012 and October 2018 involving 215 breast-cancer patients. Patient characteristics and postoperative complications were recorded, and the quality of life was rated by questionnaires.
