The direct instillation of radiolabelled conjugates in the urinary bladder is a promising path for the treatment of bladder carcinoma. The targeting of HER2/neu receptors expressed on the surface of many bladder carcinoma cells shows potential to be developed as a therapeutic strategy, and patients identified with a high risk of progression may benefit from adjuvant targeted radionuclide therap...
Amplification and/or overexpression of the human epidermal growth factor 2 (HER2) oncogene occurs in about 13-15% of invasive breast cancer and triggers breast cancer cell proliferation, survival and metastatic progression. Around half of all breast cancers with HER2 overexpression co-express hormone receptors (HR) such as those for estrogen and progesterone. Aberrant signaling through HER2 and...
Trastuzumab in the treatment of metastatic breast cancer : anticancer therapy versus cardiotoxicity.
Trastuzumab, a monoclonal antibody against the HER2 receptor, was recently approved for the treatment of metastatic breast cancer. However, 28% of patients receiving both an anthracycline and trastuzumab developed heart failure. Although HER2 overexpression has been associated with the development of cancer, HER2 receptors seem to be cardioprotective because they mediate the activation of impor...
The human epidermal growth factor receptor (HER1) and its partner HER2 are extensively described oncogenes and validated targets for cancer therapy. However, the effectiveness of monospecific therapies targeting these receptors is hampered by resistance emergence, which is frequently associated with the upregulation of other members of HER family. Combined therapies using monoclonal antibodies ...
BACKGROUND Human epidermal growth factor receptor 2 (HER2) is considered to be a therapeutic and prognostic marker in the management of breast carcinoma (BC), although discordance rates between primary and metastatic or locally recurrent lesions have been reported. METHODS One hundred and forty-eight paraffin-embedded BC tissues from patients of mean age 59.27 (33-96) years and corresponding ...
Members of the epidermal growth factor (EGF) family have been suggested as prognostic markers in patients with bladder cancer. Thus far, there has been no consensus on their usefulness. We report an analysis of six ligands and two receptors of which a subset correlate to tumor stage and survival. Biopsies from bladder cancer tumors were obtained from 73 patients followed for a median of 28 mont...
Introduction . Cyclin-dependent kinase 4/6 inhibitors are indicated in endocrine therapy for the treatment of hormone receptorpositive, HER2-negative, advanced, or metastatic breast cancer. In recent past, abemaciclib made its debut as a combinatorial partner adjuvant hormone-dependent This article demonstrates analysis our own experience introducing into clinical practice. Aim The aim study wa...
PD153035 is reported to be a specific and potent inhibitor of the epidermal growth factor (EGF) receptor tyrosine kinase and, to a lesser degree, of the closely related HER2/neu receptor. We show that PD153035 inhibits EGF-dependent EGF receptor phosphorylation and suppresses the proliferation and clonogenicity of a wide panel of EGF receptor-overexpressing human cancer cell lines. EGF receptor...
A novel frontier in the treatment of tumors that are difficult to treat is oncolytic virotherapy, in which a replication-competent virus selectively infects and destroys tumor cells. Herpes simplex virus (HSV) represents a particularly attractive system. Effective retargeting to tumor-specific receptors has been achieved by insertion in gD of heterologous ligands. Previously, our laboratory gen...
BACKGROUND Pharmacological activation of cannabinoid receptors elicits antitumoral responses in different cancer models. However, the biological role of these receptors in tumor physio-pathology is still unknown. METHODS We analyzed CB2 cannabinoid receptor protein expression in two series of 166 and 483 breast tumor samples operated in the University Hospitals of Kiel, Tübingen, and Freiburg...
