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. 3 Imatinib, a first generation TKI was followed by the second generation TKIs nilotinib, dasatinib and bosutinib and the third-generation agent ponatinib. Preventative measures include appropriate footwear to prevent injury to pressure areas. The epidermal growth factor receptor (EGFR) is implicated in various malignancies. Bracarda S, Ruggeri EM, Monti M, Merlano M, D'Angelo A, Ferraù F, Cortesi E, Santoro A; Sorafenib Working Group.. Creams tend to be better as lotions are usually thinner and water-based. We hereby report the cutaneous side effects of EGFR inhibitor therapy in 15 patients of lung and head/neck cancer. The incidence and severity of the EGFR inhibitor-induced follicular reactions are reduced by half by pre-treating with doxycycline or minocycline. Occasionally the scalp and pubic regions are involved or rarely the entire body. A patient who is having persistent diarrhea should be monitored for electrolyte imbalances, such as low magnesium and potassium levels. If folliculitis is severe, the drug may need to be stopped, and it will resolve. Results for the adverse event profile in the LUX-LUNG 3 study that resulted in the approval of afatinib in non-small-cell lung cancer (NSCLC) showed that 89% of patients treated with the agent developed rash, with 16% having rash that was grade 3 or higher (JCO 2013, 31:3327–3… On binding with an epidermal growth factor ligand outside the cell, they activate a protein kinase inside the cell. Galimont-Collen AF, Vos LE, Laurijsen AP, Ouwerkerk J, Gelderblom H. Classification and management of skin, hair, nail and mucosal side-effects of epidermal growth factor receptor (EGFR) inhibitors. 4,8,11-16. Cutaneous Adverse Effects of Small-Molecule Tyrosine Kinase Inhibitors. Sponsored content: melanomas are notoriously difficult to discover and diagnose. 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. It can appear very much like seborrhoeic dermatitis and usually settles without treatment. Monoclonal antibodies are molecules developed to attach to a particular protein in order to enhance or decrease action at that protein site. Conclusions The introduction of EGFR inhibitors into the treatment of NSCLC is an important development. 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. The EGFR pathway is a normal biologic pathway found in […] Raffaele Parrozzani. Dry skin is prevalent and managed with emollients. 2005Jul;6(7):491-500. Review. Background Epidermal growth factor receptor inhibitors (EGFRI) produce various dermatologic side effects in the majority of patients, and guidelines are crucial for the prevention and treatment of these untoward events. The COVID-19 pandemic is creating a new normal-patients need to adapt to reduce risk and understand treatment decisions. Raffaele Parrozzani. It presents as painful symmetrical red, swollen palms and soles. DermNet NZ does not provide an online consultation service. Department … EGFR is located in the cell membrane. Understand the administration, side effects and answers to frequently asked questions, Understand the administration, side effects and answers to frequently asked questions about Gavreto™. Available EGFR inhibitors include small molecule tyrosine-kinase inhibitors and monoclonal antibodies. The checkpoint inhibitor most often preceding side effects was pembrolizumab in 12 (43%). Ocular side effects due to ABT-414 can be manageable. Squamous cell carcinoma and multiple keratoacanthomas have been reported to arise in patients on sorafenib and other EGFR inhibitors. Keywords: ABT-414, confocal microscopy, cornea, depatuxizumab mafodotin, EGFR-inhibitor, Side effects from EGFR inhibitors can include: rashes, inflammation, diarrhea, and other discomforts. 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. Sunburned earlobe following minimal sun exposure due to vemurafenib, See smartphone apps to check your skin. EGFR has found to be upregulated in ker-atinocytes with UV exposure [6], and EGFR inhibitors have also been shown to increase the risk and severity of radiation-induced dermatitis [19, 20]. COX-2 inhibitors (and HDAC inhibitors) can increase the sensitivity of lung cancer cells to EGFR inhibitors (possibly via effects on the epithelial-to-mesenchymal transition). Notably, however, there has not been any proven benefit of sunscreen to prevent EGFRI-induced rash [21]. It is an early event, usually seen within the first ten days of treatment. Knowledge of dermatological side effects of EGFR inhibitors will enable the dermatologist and primary care physician to tackle them more efficiently and will allow the medical oncologist to titrate the offending drug in case of severe cutaneous toxicities. Acneiform eruptions are the earliest and most characteristic side-effect of EGFR inhibition. Cutaneous side effects of EGFR and protein kinase inhibitors. This may or may not improve if the drug is stopped. The side effects are helping scientists to learn more about skin disorders. Ther Adv Med Oncol (2020) 27 (12):1758835920907543. The side effects are generally less than with chemotherapy. Acral erythema tends to occur two to four weeks after starting treatment and is dose-dependent. The main treatment is chemotherapy, targeted therapy (such as EGFR inhibitors, the subject of this review), or both. Whereas all these agents target the same protein, EGFR, different inhibitors use different mechanisms and have different effects … It rapidly improves on stopping the drug and may not recur on restarting it. EGFR and kinase inhibitors may be particularly useful in cancer therapy as they are less toxic than more traditional chemotherapies. Paronychia can sometimes resolve spontaneously even with continued use of the drug, but it clears quickly on stopping it. Side effects of oral EGFR inhibitors (Gefitinib/ Erlotinib/Afatinib) The adverse drug reactions most commonly reported were rash (possibly itchy) and diarrhea , which in most cases were mild and manageable without intervention. Hand foot skin reaction in cancer patients treated with the multi kinase inhibitors sorafenib and sunitinib. These drugs can also cause more serious, but less common, side effects. Side effects are detectable in all treated patients and CCM documents early corneal epithelium and subbasal nerve plexus toxicity, with subsequent progressive restoration after treatment discontinuation. These tetracycline medications can also be prescribed once the rash has occurred allowing continued treatment with the EGFR inhibitor drug. In some cases, the presence of an adverse skin reaction indicates the medicine is effective in treating the tumour. Use of this class of drugs has been associated frequently with dermatological side effects termed as PRIDE complex-Papulopustules and/ or paronychia, Regulatory abnormalities of hair growth, Itching, Dryness due to EGFR inhibitors. Potent CYP3A4 inhibitors, such as certain antifungals, clarithromycin, and grapefruit juice, can dramatically increase the plasma levels of erlotinib, which can in turn worsen the side effects. They may experience frontal-temporal hair loss similar to male pattern balding. The past decade has seen the development and widespread use of EGFR inhibitors for the successful treatment of such cancers. This study sought to identify the factors determining the therapeutic efficacy of EGFR inhibitors in ESCC cells. Prevention and management of EGFR inhibitor side effects can allow the patient to remain on therapy at either a full or decreased dose, an important goal … Painless distal splinter haemorrhages are common, particularly affecting the fingernails. Available EGFR inhibitors include small molecule tyrosine-kinase inhibitors and … However, this exanthema and other cutaneous side effects can impair the quality of life of the patient and might limit the therapy with the EGFR inhibitor. Folliculitis (inflamed hair follicles) occurs in up to 40-85% of patients. 115 dm usi lesdr ire Side effects of EGFR tyrosine kinase inhibitors ing the bothersome symptoms due to the skin changes related to the TKI EGFR treatment, the patient should receive recommendations concerning the appropriate 2005;6:491-500. There are several EGFR inhibitor drugs and these cause similar side effects. Side effects are detectable in all treated patients and CCM documents early corneal epithelium and subbasal nerve plexus toxicity, with subsequent progressive restoration after treatment discontinuation. Therefore, patients need early and appropriate dermatological management. Br J Dermatol 2012:167;965-967. Leukoderma due to protein kinase inhibitor. Fingers are more frequently affected than toes. Paronychial inflammation is another typical side-effect of EGFR inhibitors that can be seen with any of the inhibitors.9, 38This disorder progresses from erythema to painful lateral nail-fold pyogenic granuloma-like lesions (figure 4). Robert C, Soria JC, Spatz A, Le Cesne A, Malka D, Pautier P, Wechsler J, Lhomme C, Escudier B, Boige V, Armand JP, Le Chevalier T. Cutaneous side-effects of kinase inhibitors and blocking antibodies. Some EGFR inhibitors are also protein kinase inhibitors. Toxicities of this agent appear similar to EGFR inhibitors (skin rash and diarrhea), although some other side effects have been described (thrombocytopenia and allergy). Rash, diarrhoea and mucositis are very common toxicities with EGFR TKIs. Some of the side-effects caused by these agents are very distressing, partly because they are chronic owing to the long duration of treatment. Types and uses of EGFR inihibtors and protein kinase inhibitors, Mechanisms of action of EGFR inhibitors and protein kinase inhibitors. M. E. Lacouture; B. L. Melosky. Download this brochure for patients suffering with EGFRI side effects. What are the cutaneous side effects of monoclonal antibody EGFR inhibitors? Cutaneous side effects of EGFR-inhibitors and their management Siegfried Segaert Dermatology Dept University Hospital Leuven Belgium 4th BADO meeting Brussels, January 14 th 2017 EGFR inhibitors Monoclonal antibodies - Cetuximab (Erbitux®) - Panitumumab (Vectibix®) Oral tyrosine kinase inhibitors It has been suggested that they are due to inhibition of vascular endothelial growth factor receptor (VEGFR). Raffaele Parrozzani. Diarrhea is … Guitar. The past decade has seen the development and widespread use of EGFR inhibitors for the successful treatment of such cancers. Overexpression of EGFR by about 30% of cancers is one reason for their excessive cell proliferation and tumour growth. We attributed the panniculitis to a side effect of EGFR inhibitors because there were no confounding elements explaining the cutaneous findings. This makes mild-to-severe side effects to the skin a possible complication of EGFR inhibitors. The development of a papulopustular, follicular exanthema during the first weeks of therapy correlates with therapeutic benefit. Lancet Oncol. Cutaneous side-effects of kinase inhibitors and blocking antibodies. If symptoms persist physicians typically utilize a step-wise approach based on severity of the rash. 2005;6:491-500. The major clinical findings being acneiform eruption and severe xerosis of skin. While the monoclonal antibody EGFR inhibitors lack many of the severe side effects commonly observed with cytotoxic chemotherapy, they are associated with a set of unique dermatological toxicities. Understand cancer treatment and its side effects from surgery to immunotherapy to complementary and integrative medicine. Many more EGFR and protein kinase inhibitors are under development. Contact us to sponsor a DermNet newsletter. Topical steroids and antiseptics may help. Paronychia refers to painful inflammation of the nail folds. CRISPR gene–editing - first human trials reported in sickle cell, beta thallasemia and cancer patients. » Volume 12,No. Swelling (oedema) of eyelids and face is common with imatinib and sunitinib. DermNet NZ does not provide an online consultation service. Evidence-based practice for the unique side effects associated with EGFR inhibitors is still evolving. Imatinib induces a rash in a third of patients who start taking it, but this rash is generally self-limited. Department of Ophthalmology, University of Padova, Padova, Italy See all articles by this author. M. E. Lacouture, L. M. Reilly, P. Gerami1 and J. Robert C, Soria J, Spatz A, et al. B-RAF is a specific threonine kinase protein. EGFR inhibitors have ... the most notable side effect being a maculopapular, ... can increase the sensitivity of lung cancer cells to EGFR inhibitors (possibly via effects on the epithelial-to-mesenchymal transition). EGFR is a protein that is found on the surface of some cells that causes cells to divide when epidermal growth factor binds to it. COX-2 inhibitors plus EGFR TKIs almost completely prevented adenoma development in Apc/min mice (47). Focusing on the detailed clinical characterization of these side effects, our group have recently reported, for the first time, the CCM analysis of corneal side effects secondary to the use of ABT-414 in a cohort of patients affected by EGFR-amplified recurrent GBM . If OTC products are not effective, a prescription medication such as diphenoxylate/atropine (Lomotil) can offer stronger relief. Lancet Oncol. The exact pathogenesis of anti-EGFR … Annals of Oncology 19: 1955–1961, 2008. The incidence may be as high as 75% to 100% of cases.2,4,8,14,16-19 Evidence suggests that severity of the skin rash might be a surrogate marker determining clinical outcome of patients receiving EGFR inhibitor treatment.1,19-21 The eruption usually occurs after 1 week of treatment. CancerConnect News: Epidermal Growth Factor Receptor (EGFR) inhibitor drugs are a type of precision cancer medicine commonly used to treat lung, colon, head and neck and other cancers that over express the EGFR.
