background: phyllodes tumor (pt) of the breast in hispanic patients is more frequently reported with large tumors and with more borderline/malignant subtypes compared with other populations. the objective of this study was to describe characteristics of patients with pt and to identify differences among subtypes in a mexican population.  methods: a retrospective study was conducted on patients ...

context triple negative breast cancer (tnbc) is a heterogeneous group of diseases that is negative for esterogen receptor (er) progesteron receptor (pr) and human epidermal growth factor receptor 2 (her2). this type of breast cancer is typically high-grade carcinomas, although low-grade tumors occur. the aim of this review is to focus on molecular classification and features, prognostic markers...

although most breast cancers are adenocarcinomas of the mammary gland, primary breast sarcomas may also arise from mammary gland mesenchymal tissue. sarcomas represent less than 1% of primary breast neoplasms. these tumors are at high risk of recurrence and are known to have poor prognosis. surgical resection is the primary treatment for these lesions and axillary lymph node dissection is not r...

primary breast sarcoma is a rare disease of the breast that comprises a heterogeneous group of malignant mesenchymal neoplasms, including angiosarcoma, liposarcoma, leiomyosarcoma, fibrosarcoma, sarcomas with bone and cartilage, and malignant fibrous histiocytoma. yet the exact incidence of primary breast sarcoma has not been reported, but it approximately accounts for less than 1% of all breas...

abstract background: breast cancer is the most prevalent cancer among iranian women, and is the fifth cause of cancer-related death in iran. most studies have reported an overall excess of 20–30% chance for a second primary cancer to develop in individuals with a first breast cancer. in this study, we evaluated different factors might have a role in increasing the incidence of a second malignan...

abstract breast cancer is a multifactorial disease. benign breast disease (bbd) is one of the most important risk factors for breast cancer. the etiology of bbd is unknown. it is divided into nonproliferative and proliferative diseases. the selection of studies will be based on titles, abstract screening, inclusion and exclusion criteria, and quality assessment. previous studies have shown that...

  Although most breast cancers are adenocarcinomas of the mammary gland, primary breast sarcomas may also arise from mammary gland mesenchymal tissue. Sarcomas represent less than 1% of primary breast neoplasms. These tumors are at high risk of recurrence and are known to have poor prognosis. Surgical resection is the primary treatment for these lesions and axillary lymph node dissection is no...

Controversy exists as to whether some breast cancers spontaneously regress without treatment. Regression of malignant breast neoplasms contradicts the long-accepted natural history of the disease and may have implications on the efficacy of breast cancer screening programs. We present a case in which a breast cancer regressed following cessation of hormone replacement therapy and consider the b...

the ataxia telangiectasia mutated gene (atm), candidate for breast cancer susceptibility gene, encode a 350-kda protein belongs to the core components of dna-damage response machinery. female at carriers have at least 5-fold increase risk for breast cancer. reduction in atm expression is shown in multiple studies in breast tissues. we aimed to perform a research to measure the atm mrna expressi...

results no significant correlation was seen in rs3743527 and rs129081 polymorphism’s allelic and genotypic frequencies between the patient group and control individuals (p value > 0.05). the average frequencies of rs129081 g and c alleles was 40 (58%) and 29 (42%), respectively. in our sample the average frequencies of rs3743527 c and t alleles, were 41 (61%) and 28 (39%), respectively. the res...
