Clinical practice guidelines for the prevention and treatment of EGFR inhibitor-associated dermatologic toxicities

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 purpose of this panel was to develop evidence-based recommendations for EGFRI-associated dermatologic toxicities. Methods A multinational, interdisciplinary panel of experts in supportive care in cancer reviewed pertinent studies using established criteria in order to develop first-generation recommendations for EGFRI-associated dermatologic toxicities. Results Prophylactic and reactive recommendations for papulopustular (acneiform) rash, hair changes, radiation dermatitis, pruritus, mucositis, xerosis/fissures, and paronychia are presented, as well as general dermatologic recommendations when possible. Conclusion Prevention and management of EGFRI-related dermatologic toxicities is critical to maintain patients’ health-related quality of life and dose intensity of antineoplastic regimens. More rigorous investigation of these toxicities is warranted to improve preventive and treatment strategies

Líquen plano bucal: considerações clínicas e histopatológicas Oral lichen planus: clinical and histopathological considerations

O líquen plano é uma das doenças dermatológicas mais comuns que acometem a cavidade bucal, com prevalência de 1% a 2% na população geral. Contudo, apesar de relativamente freqüente, o líquen plano bucal é alvo de muita controvérsia, especialmente em relação ao seu potencial de malignização. OBJETIVO: O presente trabalho tem como objetivo tecer considerações clínicas e histopatológicas a respeito do líquen plano bucal, favorecendo seu entendimento por parte dos profissionais da saúde e, conseqüentemente, reforçando a importância do acompanhamento a longo prazo dos pacientes acometidos pela doença. CONCLUSÃO: A possibilidade da lesão sofrer transformação maligna justifica a importância do acompanhamento a longo prazo dos pacientes com a doença.<br>Oral lichen planus is one of the most common dermatological diseases presenting in the oral cavity; the prevalence in the general population is 1% to 2%. Although relatively frequent, oral lichen planus is the target of much controversy, especially in relation to its potential for malignancy. AIM: This study aimed to make clinical and histopathological considerations regarding oral lichen planus to increase the level of knowledge about this condition among health professionals, underlining the importance of long-term follow-up of these patients. CONCLUSION: The possibility of this lesion to turn malignant justifies the importance of long term follow up for patients with such disease
