Taking them with food will increase their bioavailability, thus causing heightened side effects. Drawbacks of EGFR inhibitor therapies are cardiac and renal side-effects, skin toxicity, and intrinsic or acquired resistance to therapy; these limit the duration or dosage of treatment , . These drugs can also cause more serious, but less common, side effects. Paronychia refers to painful inflammation of the nail folds. Tubular injury is common and mainly due to monoclonal antibodies while glomerulopathy is rare and related to various anti-EGFR agents. Drug- induced alopecia (hair loss) is less common than folliculitis and tends to occur later, usually at 2-3 months.

They target the amino acids tyrosine, threonine and serine. Chemotherapy agents interfering with EGFR or FGFR pathways have known ocular side effects such as acquired trichomegaly, persistent corneal epithelial defects, dysfunctional tear syndrome, blepharitis, meibomitis, iridocyclitis, and lid ectropion, etc. For this reason the treatment of common cutaneous side effects of EGFR inhibitors has become important: they stigmatize the patient in daily life and may lead to efficacious therapie being discontinued.

Although effective in the treatment of many cancers, EGFR inhibitors often result in adverse reactions in the skin, which occur in at least half of treated patients. VEGFR is thought involved in the repair of the delicate spiral capillaries under the nail, which are subject to frequent injury. Whereas all these agents target the same protein, EGFR, different inhibitors use different mechanisms and have different effects … Epidermal growth factor receptor (EGFR) - Tyrosine Kinase inhibitors (TKI) like erlotinib and gefitinib have been approved as monotherapy for the treatment of patients with locally advanced or metastatic non small cell lung cancer (NSCLC) after failure of at least one prior chemotherapy regimen. Many more EGFR and protein kinase inhibitors are under development. The small molecule kinase inhibitors often block multiple enzymes meaning means there is some cross over in the actions and side effects of these drugs. Skin toxicity among patients under treatment with EGFR inhibitors has protean manifestations because its receptor is highly expressed in keratinocytes, sebocytes, and outer root sheath of hair follicle. Discomfort may necessitate brief interruption of treatment. Bracarda S, Ruggeri EM, Monti M, Merlano M, D'Angelo A, Ferraù F, Cortesi E, Santoro A; Sorafenib Working Group.. M. E. Lacouture, L. M.

Avoid foods that exacerbate diarrhea (eg, raw fruits and vegetables; whole grain breads; nuts; popcorn; skins; seeds; legumes; and greasy, fried, high-fat foods). The specific receptors found on the cancer determine which drug is likely to be of benefit. DermNet NZ does not provide an online consultation service. The intensity of the folliculitis can fluctuate even when continuing to take the drug. What advice do lung cancer experts have to help EGFR lung cancer patients manage these side effects? What are the cutaneous side effects of monoclonal antibody EGFR inhibitors? Monoclonal antibodies are molecules developed to attach to a particular protein in order to enhance or decrease action at that protein site. EGFR = epidermal growth factor receptor; PDGFR = platelet-derived growth factor receptor; VEGFR = vascular endothelial growth factor receptor. Vitamin D is important for bone health and has other benefits, don't get caught in the dark this winter. However, EGFR inhibitors have a built-in advantage over classic chemotherapy: “because we now know the targets of these drugs, their side effects can be specifically studied and independently treated,” the study’s senior author, Maria Sibilia, PhD, of the Medical University of Vienna and Comprehensive Cancer Center in Austria, told JAMA. The higher incidence of erlotinib and afatinib cutaneous effects in comparison with gefinitib, could justify why the panniculitis did not occur in the first place under treatment with gefitinib. Annals of Oncology 19: 1955–1961, 2008. Though potentially effective against cancer, EGFR inhibitors may also interfere with normal cells, as EGFR is present on some healthy cells, notably skin cells. This study sought to identify the factors determining the therapeutic efficacy of EGFR inhibitors in ESCC cells.
