BACKGROUND The epidermal growth factor receptor (EGFR) is a surrogate marker for basal-like breast cancer. A recent study suggested that EGFR may be used as a target for breast cancer treatment. METHODS A total of 706 invasive ductal carcinomas (IDC) of the breast were immunophenotyped, and 82 cases with EGFR protein expression were studied for EGFR gene amplification. RESULTS EGFR protein ...

INTRODUCTION Estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2) expression are crucial in the biology of breast carcinoma. HER-2/neu gene is amplified and overexpressed in 15-30% of invasive breast cancers. HER-2-positive breast cancers have worse prognosis than HER-2 negative tumors and possess distinctive clinical features. The aim of this ...

Kanker payudara merupakan suatu keadaan dimana sel telah kehilangan pengendalian dan mekanisme normalnya, sehingga terjadi pertumbuhan yang tidak normal, cepat, terkendali pada jaringan payudara. dapat menyebabkan kematian kaum wanita. Andrographolide salah satu senyawa antikanker terkandung tanaman sambiloto ( Andrographis Paniculata (Burm F) Ness.). Adapun reseptor Human Epidermal Growth Fact...

Mutations of germ-cell line TP53 gene are mainly reported in Li–Fraumeni syndrome(LFS). LFS-associated breast cancers are both hormone receptor and human epidermal growth factor receptor 2 positive. The purpose of this study is presentation of one case of LFS, associated with familial hyperlipidemias. A 52-year-old woman referred to clinic of oncology with a pain in the left breast. Her patholo...

HER-2 belongs to the human epidermal growth factor receptor (HER) family. Via different signal transduction pathways, HER-2 regulates normal cell proliferation, survival, and differentiation. Recently, it was reported that MCF10A, BT474, and MDA-MB-231 cells bearing the HER2 K753E mutation were resistant to lapatinib. Present study revealed that HER-2 mutant K753E showed some contrasting behavi...

Human carcinomas frequently express one or more members of the epidermal growth factor receptor family. Two family members, epidermal growth factor receptor (EGFR) and c-erbB2/neu (HER2), homodimerize or heterodimerize upon activation with ligand and trigger potent mechanisms of cellular proliferation, differentiation and migration. In this study, we examined the effect of the anti-EGFR monoclo...

Medulloblastoma is the most frequent malignant pediatric brain tumor with a dismal prognosis in 30% of cases. We examined the activity of AEE788, a dual inhibitor of human epidermal receptor (HER) 1/2 and vascular endothelial growth factor receptor (VEGFR) 1/2, in medulloblastoma preclinical models. Established lines (Daoy and D283), chemoresistant (Daoy(Pt)), and ectopically HER2-overexpressin...

Abstract Introduction and importance IPLC (Invasive Pleomorphic Lobular Carcinoma) accounts for less than 1% of breast cancer. To the best our knowledge, this is one few reported cases in with multiple metastases. The patient's general condition got improved after treatment, which has a certain reference treatment kind patient future. Case presentation A 42-year-old female malignant cells were ...
