ALGORITHMS FOR MANAGEMENT OF PATIENTS WITH ADVERSE EVENTS ON THERAPY WITH TYROSINE KINASE INHIBITORS EGFR

The tyrosine kinase inhibitors (TKIs) of the epidermal receptor growth factor (EGFR) such as gefitinib, erlotinib and afatinib, are the standard first-line therapy in locally advanced and metastatic non-small cell lung cancer (NSCLC) with frequent mutations of the EGFR gene. These drugs are more effective from the point of view of frequency response (FR) and survival without progression (SWP), less toxic and better tolerated than the standard two-component chemotherapy based on platinum drugs. The most frequent adverse events (AE) are gastrointestinal (GI) (diarrhea and stomatitis/mucositis) and dermatological (rash, dry skin and paronychia). They are usually mild, but in some cases symptoms can be moderate and more severity and have a negative impact on quality of life (QOL) of the patient and can require dose adjustment or discontinuation of treatment. Management of AEs, including preventive measures, supportive therapy, temporary cancellation and a reduction in the dose of the drug is important. Recommendations for the prevention and treatment of dermatological toxicity (rash, dry skin and paronychia) and toxicity for the gastrointestinal tract (diarrhoea, stomatitis and mucositis) related to therapy TKI-EGFR are developed. These guidelines describe in detail supportive therapy, the temporary discontinuation of the treatment and reducing the dose of the drug for KTI-EGFR
