Abstract:
Advances in understanding of the mechanisms involved in oncogenesis have led to the development of targeted therapies such as epidermal growth factor receptor inhibitors (EGFRIs), targeting a variety of molecular structures and able to inhibit aberrantly activated oncogenic pathways. Their use made treatment more tolerable with significant reduction of systemic adverse effects. However, EGFRIs are associated with toxicities affecting the skin and adnexal structures that affect the majority of treated patients. Trichomegaly of eyelashes is a unique side-effect, seen in prolonged treatment with EGFRI. It is essential to be familiar with this adverse effect, its potential complications, long-term sequelae, and available effective treatment strategy in order to appropriately manage these patients.
Insights
Epidermal growth factor receptor inhibitors (EGFRIs) offer targeted cancer therapy with fewer systemic side effects. However, prolonged use can cause unique skin toxicities, including eyelash trichomegaly, requiring specific management strategies.
Area of Science:
- Oncology
- Dermatology
- Pharmacology
Background:
- Targeted therapies like epidermal growth factor receptor inhibitors (EGFRIs) have revolutionized cancer treatment by inhibiting oncogenic pathways.
- EGFRIs offer improved tolerability and reduced systemic adverse effects compared to traditional chemotherapy.
Observation:
- EGFRIs commonly cause toxicities affecting the skin and adnexal structures in a majority of patients.
- Trichomegaly of the eyelashes is a distinctive side effect observed with prolonged EGFRI treatment.
Findings:
- Understanding the mechanisms of oncogenesis has enabled the development of targeted therapies.
- EGFRIs, while effective, present unique dermatological side effects like eyelash changes.
Implications:
- Familiarity with EGFRI-induced trichomegaly is crucial for effective patient management.
- Knowledge of potential complications and treatment strategies for this unique side effect is essential for clinicians.
