Occult breast cancer (OBC) is characterized by metastatic presentation of undetectable tumor on imaging exams. OBC a rare disease (accounting for 0.3% to 1.0% all cancers) that represents major diagnostic challenge. The aim this study was report case with primary multiple cutaneous metastases subsequent emergence bone metastasis. A 70-year female patient had lesions in the left cervical region, breast, axillary subscapular three chirodactylus right hand and hand. Imaging tests (mammogram,...

Introduction Triple-negative breast cancer (TNBC) is a molecular subtype in which estrogen (ER)/progesterone receptor (PR) and human epidermal growth 2 (HER2) expression does not occur. The objective of this study was to analyze the impact pathologic complete response (pCR) after neoadjuvant chemotherapy on prognosis triple-negative patients. Methods This cohort conducted private-sector oncology clinic located city Teresina, Brazil. Medical charts 532 patients treated from 2007 2020 were...

SUMMARY OBJECTIVE: Triple-negative breast cancer (TNBC) is characterized by lack of estrogen receptor, progesterone and human epidermal growth factor receptor 2 (HER2) expression accounts for 15–20% all cancers. This study aims to analyze prognostic factors related a reduction in overall survival (OS), disease-free (DFS), risk mortality recurrence TNBC. METHODS: retrospective observational cohort study. Medical records 532 patients with diagnosed from 2007 2020 were analyzed. Of these...

Abstract Introduction: Male breast cancer (MBC) is a rare disease that accounts for 1% of cancers. The Oncotype DX test (a genomic signature assesses the expression 21 genes to estimate recurrence score [RS]) has been widely used in MBC select patients adjuvant chemotherapy. Objective: To describe 5 cases which nomogram was predict probability having high and need perform signature. Materials methods: Case series study five with treated between 2007 2020 at institution Teresina (Brazil) were...

A COVID-19 é uma doença causada pela nova cepa viral da Família Coronaviridae (Sars-Cov-2), que surgiu na província de Hubei, China, em Dezembro 2019, e vem se disseminando rapidamente pelo mundo desde então. Assim, frente à importância infecção Sars-Cov-2 para o atual cenário mundial, também reflete no Piauí, devido relevância dados epidemiológicos estabelecimento políticas Saúde Pública mais efetivas, este estudo objetivou analisar a evolução epidemiológica dos casos estado do Piauí 2...

Triple-negative breast cancer (TNBC) is an uncommon molecular subtype (representing 15%–20% of cancers) characterized by the non-expression estrogen receptor, progesterone and human epidermal growth receptor factor 2. More aggressive lethal, TNBC often associated with pathogenic variants in BRCA1/2 genes. This study aimed to describe a series seven cases patients All were female under 50 years age at diagnosis. Four them presented family history and/or other neoplasms. The predominant...

Introduction: Occult breast cancer (OBC) is defined as a metastatic carcinoma that occurs mainly in the axillary lymph nodes, derived from primary malignant tumor undetectable by clinical and radiological analyses. OBC rare disease accounting for 0.3%–1.0% of all cancers, which more commonly at age around 55 years. The represents event (especially with manifestation systemic metastases) major diagnostic challenge. Thus, aim this study was to report case cutaneous metastases subsequent...

Introduction: Metaplastic breast carcinoma (MBC) is understood as a heterogeneous group of malignant tumors, which exhibits the transformation part or its entire glandular carcinomatous component into nonglandular by means epithelial and mixed mesenchymal differentiation. The MBC rare aggressive cancer, accounting for approximately 1% all tumors that have worse prognosis. aim this study was to describe four cases MBC, analyzing progression patients in mean follow-up 25 months (11–43 months)....

Introduction: Male breast cancer (MBC) is a very rare disease, which accounts for approximately 1.0% of all cancers and around 0.17%–1.0% male malignancies, more common in the age group 60 years, 93.7% cases MBC are histologically classified as invasive carcinoma no special type (ICNS). Treatment (i.e., surgery, radiotherapy, chemotherapy, hormone therapy) prognosis similar to women. The aim this study was describe five analyze occurrence relapse follow-up 88 months (36–180 months).
