Nonlactational Mastitis in Western Brazilian Amazon Mastitis Cases.

Chronic mastitis varies in etiology between its lactational and nonlactational forms and can be challenging to diagnose. This study aimed to assess the epidemiological profile and diverse etiologies of nonlactational mastitis in Amazonas, Brazil, focusing on distinguishing between tuberculous mastitis (TM) and idiopathic granulomatous mastitis (IGM). This is a retrospective and prospective study that was carried out at the mastitis outpatient clinic of Fundação de Medicina Tropical Doutor Heitor Vieira Dourado from 2013 to 2021 and evaluated epidemiological data, imaging, and laboratory tests.

External breast prostheses after mastectomy: production and selection of a low-cost functional model to be performed in developing countries.

Introduction: Breast cancer is one of the most common types of cancer affecting women. Despite advancements in early diagnosis, neoadjuvant therapy, and various treatment modalities, mastectomy remains a common procedure for many women. Although some women opt for reconstructive surgery (BR), many do not have the indication, desire, or opportunity to undergo this procedure.

Training in oncoplastic surgery for mastologists.

Objective: The radical change in the treatment of breast cancer has promoted the necessity for more comprehensive training of the professionals involved, ensuring the preservation of oncological safety while also allowing for cosmetic interventions to benefit breast cancer survivors. The aim of this study was to present the methods employed in the training of breast surgeons, highlighting the importance of oncoplasty and breast reconstruction.

Methods: A literature review was conducted in two databases, identifying articles related to medical education in the context of oncoplastic surgery and breast reconstruction.

Evaluation of upper limb lymphoedema and diagnostic accuracy of bioimpedance spectroscopy. A comprehensive validation in a Brazilian population.

Unlabelled: Lymphoedema is a complication of breast cancer treatment. Its early diagnosis is related to a good prognosis for lymphoedema treatment. The bioimpedance spectroscopy (BIS) evaluates changes in extracellular fluid.

Extreme oncoplasty: past, present and future.

Breast surgery has evolved from mastectomy to breast-conserving surgery (BCS). Breast oncoplastic surgery later emerged with the inclusion and development of techniques used in plastic surgery for breast neoplasms. Recently, a new paradigm has been considered for mastectomy candidates with large multifocal and multicentric tumours, designated extreme oncoplasty (EO), which has allowed new techniques to be applied to tumours that would have been ineligible for BCS before.

Are there clinical and subclinical/pathological forms of Paget's disease of the breast?

Introduction: Breast disease management has changed over recent decades, related to molecular subtype, oncoplastic surgery and targeted therapies. Nevertheless, literature on Paget's disease of the breast (PDB), initially described as a clinical entity and now considered a multifocal/multicentric disease.

Methods: PDB was classified as clinical in the presence of areolar abnormalities and as subclinical/pathological in all other cases.

Ancestry and self-reported race in Brazilian breast cancer women.

Objective: This study aimed to evaluate the association between self-reported race/color and ancestry in Brazilian patients with breast cancer.

Methods: This was an observational, transversal, epidemiological study, evaluating race and ancestry in 1,127 patients with breast cancer. For genetic ancestry, a 46-AIM-INDEL panel was used.

Breast reconstruction for locally advanced breast cancer previously submitted to mastectomy and an ipsilateral thoracoabdominal dermofat (ITADE) flap.

Thoracoabdominal (TA) flaps are a good option for primary closure of small and medium defects after mastectomy for locally advanced breast tumours. Although they have a higher rate of necrosis than myocutaneous flaps, they can be easily performed by breast surgeons. Few studies on this procedure have been reported, and we have been unable to identify any prior publications reporting breast reconstruction with TA flaps.

Molecular subtypes as a prognostic breast cancer factor in women users of the São Paulo public health system, Brazil.

Objective: This study aimed to analyze the prognosis of women with breast cancer by molecular subtypes, sociodemographic variables, and clinical and treatment characteristics.

Methods: This hospital-based retrospective cohort study analyzed 1,654 women over 18 years of age diagnosed with invasive breast cancer from 2000 to 2018. Data were extracted from Brazil's Oncocenter Foundation of São Paulo.

Criteria for selection and classification of studies in medical events.

Objective: The aim of this study was to evaluate the impact of study methodology and evaluation type on the selection of studies during the presentation of scientific events.

Methods: A prospective, observational, transversal approach was applied to a cohort of studies that were submitted for presentation at the 2021 Brazilian Breast Cancer Symposium. Three forms of criteria (CR) were presented.

Lymph node microcalcifications after neoadjuvant chemotherapy: A therapeutic response marker.

Lymph node microcalcifications are rare events, and when they are accompanied by neoplasia, they usually seem to be associated with a metastatic condition. We present a case of a patient with breast cancer and lymph node microcalcifications undergoing neoadjuvant chemotherapy (NCT). A change in the calcification pattern towards becoming coarse was observed.

Does breast oncoplastic surgery improve quality of life?

Breast Oncoplastic Surgery (OS) has established itself as a safe procedure associated with the treatment of breast cancer, but the term is broad, encompassing procedures associated with breast-conserving surgeries (BCS), conservative mastectomies and fat grafting. Surgeons believe that OS is associated with an increase in quality of life (QOL), but the diversity of QOL questionnaires and therapeutic modalities makes it difficult to assess from the patient's perspective. To answer this question, we performed a search for systematic reviews on QOL associated with different COM procedures, and in their absence, we selected case-control studies, discussing the main results.

HPV-positive cervical squamous cell carcinoma metastasis to the breast, mimicking primary tumor.

Introduction: Metastatic disease to the breast is a rare condition, with contralateral breast metastasis being the most common primary site.

Case Presentation: We present the case of a patient who underwent treatment for an HPV positive squamous cell carcinoma (SCC) of the cervix who, during follow-up, complained of a nodule in her left breast. Anatomopathological results indicating squamous carcinoma, which was not able to be differentiated from breast metaplastic carcinoma.

Breast-conserving surgery with the geometric compensation/split reduction technique. Indications, oncologic safety and cosmesis. A cohort series and systematic review of the literature.

Background: The Geometric Compensation Technique (GCT) and the Split Reduction Technique (SRT) enables breast conserving surgery (BCS) in selected patients with breast cancer initially candidates to mastectomy.

Methods: Observational study of patients with breast cancer who underwent GCT consecutively treated. Evaluated retrospectively: indications, clinical characteristics, surgical features and recurrences.

Use of Double Myocutaneous Flap after Extended Resection of Locally Advanced Ulcerated Breast Carcinoma.

Locally advanced ulcerated breast neoplasm is a condition that frequently occurs in developing countries. Generally, it is centrally localized and submitted to neoadjuvant therapy; thereafter, upon disappearance of the ulceration, it is submitted to radical mastectomy. Presence of axillary infiltration and ulceration with incomplete response makes it necessary for the use of surgical flaps for skin closure.

Phase III study of the European Organisation for Research and Treatment of Cancer Quality of Life cancer survivorship core questionnaire.

Purpose: The purpose of this study is to develop a European Organisation for Research and Treatment of Cancer Quality of Life Group (EORTC QLG) questionnaire that captures the full range of physical, mental, and social health-related quality of life (HRQOL) issues relevant to disease-free cancer survivors. In this phase III study, we pretested the provisional core questionnaire (QLQ-SURV111) and aimed to identify essential and optional scales.

Methods: We pretested the QLQ-SURV111 in 492 cancer survivors from 17 countries with one of 11 cancer diagnoses.

Oncoplastic Surgery in Breast-Conserving Treatment: Patient Profile and Impact on Quality of Life.

Background: Breast-conserving treatment (BCT) provides better quality of life (QL) than mastectomy without reconstruction. Oncoplastic surgery (OS) encompasses a series of surgical techniques, increasing the indications for BCT, but few studies have evaluated the impact on QL in patients who undergo BCT with OS.

Materials And Methods: A prospective, cross-sectional study was conducted in women who underwent BCT.

New criteria for breast symmetry evaluation after breast conserving surgery for cancer.

Objective: to evaluate symmetry after breast-conserving surgery (BCS) for cancer.

Methods: a prospective study of patients undergoing BCS. These patients were photographed using the same criteria of evaluation.

Sentinel Lymph Node Biopsy in T3 and T4b Breast Cancer Patients: Analysis in a Tertiary Cancer Hospital and Systematic Literature Review.

Introduction: Breast cancer represents the most common type of cancer among women in the world. The presence and extent of axillary lymph node involvement represent an important prognostic factor. Sentinel lymph node biopsy (SLNB) is currently accepted for T1 and T2 with negative axillae (N0); however, many patients with T3-T4b tumors with N0 are often submitted to unnecessarily axillary lymph node dissection.

Oncoplastic Surgery: Does Patient and Medical Specialty Influences the Evaluation of Cosmetic Results?

Background: Oncoplastic surgery (OS) has added plastic surgery concepts and techniques to the breast cancer surgery. However, reports of the impact of OS on cosmesis after breast-conserving surgery (BCS) are limited in the literature.

Patients And Methods: This cross-sectional prospective study included patients who underwent BCS.
