Breast Conservative Surgery

BACKGROUND: Trials have demonstrated the safety of omitting completion axillary lymph node dissection in patients with cT1-2 N0 breast cancer operated with breast-conserving surgery who have limited metastatic burden in the sentinel lymph node. The aim of this registry study was to provide insight into the oncological safety of omitting completion axillary treatment in patients operated with mastectomy who have limited-volume sentinel lymph node metastasis. METHODS: Women diagnosed in 2013-2014 with unilateral cT1-2 N0 breast cancer treated with mastectomy, with one to three sentinel lymph node metastases (pN1mi-pN1a), were identified from the Netherlands Cancer Registry, and classified by axillary treatment: no completion axillary treatment, completion axillary lymph node dissection, regional radiotherapy, or completion axillary lymph node dissection followed by regional radiotherapy...

BACKGROUND: Oncoplastic breast conservation has been classically divided into volume displacement (VD) or volume replacement (VR) techniques. There have been few descriptions of merging these two approaches. This report describes our experience combining Wise-pattern VD and autologous VR to repair extensive partial mastectomy defects in patients with ptosis. METHODS: A retrospective chart review was performed for patients who underwent combined Wise-pattern VD surgery and autologous VR by the author from June 2017 to June 2023, with at least 6 months follow-up...

BACKGROUND: Fibroadenoma (FA) is the most common tumor found in young women, although it can occur in any age group. Ductal carcinoma in situ (DCIS) that is confined in a FA is rare; it is most frequently reported as an incidental finding. CASE SUMMARY: We report a case of DCIS within a FA in a 46-year-old female without cancer-related personal and family histories. The patient was diagnosed with a breast conglomerate of nodules and was followed for 1 year. In the current control image study, we found suspicious microcalcification, as a new finding, within one of the nodules...

BACKGROUND: Mastectomy has been the standard surgical treatment for ipsilateral breast tumor recurrence (IBTR). Recently, there has been growing interest in repeat breast-conserving surgery (rBCS) for IBTR among breast surgeons; however, there is currently little information regarding patient preferences for surgical procedure for IBTR. The purpose of this study was to evaluate preference for surgical procedure (mastectomy vs. rBCS) among breast cancer patients who had undergone salvage surgery for IBTR...

PURPOSE: To assess radiation-induced fibrosis (RIF) using shear-wave elastography (SWE) in patients with breast cancer who received radiotherapy (RT) after breast conserving surgery. METHODS: Forty-one patients were enrolled in a prospective study before RT. SWE and B-mode ultrasonography were performed to measure elasticity. For quantitative measurement, the maximum elasticity value was measured in the tumor bed and non-tumor bed of the treated breast, and contralateral breast before RT and at 3, and 12 months after RT...

BACKGROUND: The moderate deep inspiratory breath hold (mDIBH) is a modality famed for cardiac sparing. Prospective studies based on this are few from the eastern part of the world and India. We intend to compare the dosimetry between mDIBH and free-breathing (FB) plans. METHODS: Thirty-two locally advanced left breast cancer patients were taken up for the study. All patients received a dose of 50 Gy in 25 fractions to the chest wall/intact breast, followed by a 10-Gy boost to the lumpectomy cavity in the case of breast conservation surgery...

The clinical data of 23 patients undergoing real-time echocardiography-guided infusion port implantation in the Breast Center of Tsinghua Changgung Hospital in Beijing from January to July 2021 were analyzed. The length of catheter insertion L1 was initially estimated using surface measurement method in all patients. Intraoperatively, transthoracic echocardiography was applied using the parasternal four-chamber view to visualize the catheter image within the right atrium, and the length of catheter insertion L2 was recorded under the guidance of echocardiography...

BACKGROUND: Breast cancer-related lymphedema (BCRL) is a potentially disabling and often irreversible consequence of breast cancer treatment, caused by the mechanical incompetence of the lymphatic system, resulting in reduced drainage capacity and functional overload due to an excessive volume of interstitial fluid surpassing the system's transport capacity in the arm. We wanted to determine the impact and explore the differences in independent risk factors for the occurrence of BCRL; incidence of BCRL over a five-year period at the Institute of Oncology Vojvodina in Sremska Kamenica and to answer the research question regarding the influence of the prehabilitation program on the overall incidence of BCRL during the observed five-year period...

INTRODUCTION AND IMPORTANCE: Idiopathic granulomatous mastitis is an uncommon, long-lasting inflammatory condition of the female breast. It is characterized by the development of a painful breast mass that gradually increases in size. This condition is benign and its cause is unknown. It primarily affects women of childbearing age who have a history of pregnancy and breastfeeding. The main feature of idiopathic granulomatous mastitis is the presence of chronic inflammation in the breast...

Poly-ADP ribose polymerase inhibitor (PARPi) is approved for HER2-negative advanced breast cancer with BRCA1/2 mutation. In recent years, many studies have explored the application of PARPi in neoadjuvant therapy, but failed to reach a unified conclusion. PubMed, Clinicaltrials.gov, Cochrane CENTRAL, Embase, and key oncological meetings for trials were searched for studies reporting neoadjuvant regimens with PARPi in HER2-negative breast cancer. Pathological complete response (pCR), residual cancer burden (RCB), breast-conservation surgery rate (BCSR), clinical response, and adverse events were extracted and pooled in a meta-analysis using the Mantel Haenszel random/fixed effects model...

BACKGROUND: Axillary lymph node dissection (ALND) in breast cancer management, necessitates a nuanced understanding of complications that may impede treatment progression. This study scrutinize the impact of Haemoblock hemostatic solution, evaluation it's potential in reducing seroma complication by controlling lymph flow and obliterating axillary dead space. METHOD: A prospective, randomized, double-blinded controlled trial was conducted with 58 patients undergoing breast conserving surgery (BCS) and ALND, stratified into two groups: Group A (ALND + Haemoblock, n = 29) and Group B (ALND + placebo, n = 29)...

OBJECTIVES: Neutrophils are the most common type of leukocyte in mammals and play an essential role in the innate immune system and anti-cancer responses. However, recent studies identified the presence of tumor-associated neutrophils (TANs) as a poor prognostic factor. The present study investigated whether relationships exist between TANs and the clinicopathological factors and genetic status of breast cancer. METHODS: A total of 196 breast cancer patients with sufficient biopsy, breast-conserving surgery, or mastectomy specimens between 2014 and 2021 in Hokuto Hospital were included...

Diagnosis of ductal carcinoma in situ (DCIS) represents about 25% of newly diagnosed breast cancers. There is debate about the benefit of sentinel lymph node biopsy (SLNB) for further staging and guidance of therapy in patients with DCIS. Current guidelines recommend SLNB for patients undergoing breast-conserving therapy (BCT) for DCIS. Utilizing superparamagnetic iron oxide (SPIO) nanoparticles as a tracer may allow for a delayed SLNB (d-SLNB), typically within a month of injection. We present our experience with a patient who due to complications from surgery could not complete her d-SLNB for 165 days...

BACKGROUND: Breast cancer is the most common malignancy and remains the first cause of death related to cancer among Vietnamese women, with an incidence of 21,555 cases in 2020. Most breast cancer patients present with invasive disease and relatively large tumor sizes. While oncoplastic surgery (OPS) are commonly applied in Western countries, data on Asian population remains relatively limited. OBJECTIVE: This study aims to assess the outcomes of level-2 oncoplastic techniques in breast-conserving surgeries at the Vietnam National Cancer Hospital...

INTRODUCTION: Oncoplastic breast surgery includes volume replacement as well as volume displacement. Autologous tissue is the preferred approach for volume replacement and includes chest wall perforator flaps (CWPF). Although described more than a decade ago, CWPFs have not been adopted widely in clinical practice till recently. We report the largest single-centre institutional data on CWPFs. PATIENTS AND METHODS: The study includes all patients who underwent breast conservation surgery (BCS) using CWPFs from January 2015 to December 2022...

INTRODUCTION: Atypical or B3 lesions comprise a heterogeneous group of uncertain malignant potential. B3 lesions diagnosed on core biopsy are usually recommended for diagnostic open biopsy. Identifying factors which could allow conservative management of B3 lesions would be helpful in avoiding unnecessary surgery. The aim of this study was to identify the upgrade rate to malignancy for B3 core biopsy lesions and to compare characteristics of lesions which were malignant and benign at excision...

Human epidermal growth factor receptor 2 (HER2)-targeted therapy has transformed the treatment paradigm for early-stage HER2-positive breast cancer, providing personalized and effective interventions. This comprehensive review delves into the current state of HER2-targeted therapies, emphasizing pivotal clinical trials that have demonstrated their substantial impact on long-term outcomes. Combination therapies that integrate HER2-targeted agents with chemotherapy exhibit enhanced tumor responses, particularly in neoadjuvant settings...

BACKGROUND: Extramammary Paget disease is a relatively rare and less malignant intraepithelial adenocarcinoma. t is found in areas with abundant distribution of apocrine sweat glands such as the external genitalia, external genitalia, and perianal area, with fewer armpits. The disease progresses slowly and is prone to misdiagnosis in clinical practice. METHODS: We retrospectively analyzed a female patient. She had a left axillary mass for more than 2 years. Recently, the mass increased and the surface skin was ulcerated...

BACKGROUND: Globally, most of the randomised trials with hypofractionation in patients with breast cancer have used 3-dimensional conformal radiotherapy technique (3D-CRT). As facilities for 3D-CRT technique may not be available in low-resource settings, there is a need to see if hypofractionation is feasible and safe with 2-dimensional (2-D) technique. In this study, we compared a 3-week radiation schedule with a 2-week schedule of hypofractionated radiotherapy in patients with breast cancer with 2-D technique...

BACKGROUND: The accurate evaluation of surgical margins holds crucial importance in determining the success of breast-conserving surgery (BCS). The aim of this study was to introduce a novel technique for the positioning of surgical margins in BCS while highlighting its advantages. METHODS: This study included a cohort of breast cancer patients who underwent BCS. The patients were categorized into two groups: one group underwent BCS with the traditional palpation-guided method, and the other with the 3D-MPT technique...
