: The aim of ASTRIS, a real-world study, was to assess the safety and efficacy of osimertinib in patients with locally advanced or metastatic (stage IIIB-IV) epidermal growth factor receptor (EGFR) T790M mutation-positive non-small cell lung cancer (NSCLC) who had received prior EGFR-tyrosine kinase inhibitor (TKI) therapy. Here, we describe the Belgian subset of the global ASTRIS study.: Patients received osimertinib orally as one 80 mg tablet once daily until disease progression or unacceptable toxicity. Socio-demographic data, medical history, disease progression and survival status were collected and molecular testing for EGFR status was performed. Safety was also assessed. All collected data were summarized using descriptive statistics.: Of the 31 Belgian patients enrolled in the study, 9 (29.0%) discontinued treatment for disease progression and 5 (16.1%) due to other reasons. Among the 31 patients treated with osimertinib, 16 (51.6%, 95% CI 33.1-69.8) had a clinical response and 13 (41.9%) had stable disease as best response assessed by the investigator, with a disease control rate of 93.5%. The clinical response rate was 66.7% (6/9) in patients with brain/leptomeningeal metastases and 50.0% (4/8) in patients without brain/leptomeningeal metastases. About one third of the patients (11/31) reported at least one adverse event (AE) (35.5%) or serious AE (10/31; 32.3%) and 3/31 (9.7%) patients discontinued treatment due to AEs.: We here demonstrate the effectiveness of osimertinib in a real-world setting in Belgian patients with locally advanced or metastatic T790M-positive NSCLC who had received previous EGFR-TKI treatment. No new safety signals were identified.

A 6-kDa polypeptide growth factor initially discovered in mouse submaxillary glands. Human epidermal growth factor was originally isolated from urine based on its ability to inhibit gastric secretion and called urogastrone. EPIDERMAL GROWTH FACTOR exerts a wide variety of biological effects including the promotion of proliferation and differentiation of mesenchymal and epithelial cells.
A cell surface receptor involved in regulation of cell growth and differentiation. It is specific for EPIDERMAL GROWTH FACTOR and EGF related peptides including TRANSFORMING GROWTH FACTOR ALPHA, amphiregulin, and heparin-binding EGF-like growth factor. The binding of ligand to the receptor causes activation of its intrinsic tyrosine kinase activity and rapid internalization of the receptor-ligand complex into the cell.
Factor isolated in a variety of tissues including epithelium, and maternal decidua. It is closely related to EPIDERMAL GROWTH FACTOR and binds to the EGF receptor. TGF-alpha acts synergistically with TGF-beta in inducing phenotypic transformation, but its physiological role is unknown.
Mucocellular carcinoma of the ovary, usually metastatic from the gastrointestinal tract, characterized by areas of mucoid degeneration and the presence of signet-ring-like cells. It accounts for 30%-40% of metastatic cancers to the ovaries and possibly 1%-2% of all malignant ovarian tumors. The lesions may not be discovered until the primary disease is advanced, and most patients die of their disease within a year. In some cases, a primary tumor is not found.

A well-characterized neutral peptide believed to be secreted by the LIVER and to circulate in the BLOOD. It has growth-regulating, insulin-like and mitogenic activities. The growth factor has a major, but not absolute, dependence on SOMATOTROPIN. It is believed to be a major fetal growth factor in contrast to INSULIN-LIKE GROWTH FACTOR I, which is a major growth factor in adults.
GILOTRIF (afatinib) is a kinase inhibitor indicated for the first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 (L8...
