- W2901849740 abstract "Controversy exists regarding the safety of agents that systemically inhibit epidermal growth factor receptor (EGFRi) in oncologic patients in terms of toxicity to the ocular surface. We performed a prospective clinical study comparing the ocular surface toxicity of systemic EGFRi between a case and a control group. Patients with lung or colon cancer were divided in two groups: 25 patients treated with systemic EGFRi and 25 control patients without EGFRi treatment. Patients in both groups were chemotherapy naive. Four visits were scheduled in a one year period comparing signs and symptoms in terms of symptom questionnaires (SIDEQ, OSDI and AVS), corneal fluorescein staining (Oxford test), tear production (Schirmer's test) and a quantitative evaluation of conjunctival chemosis and hyperemia. Basal epithelial cell density (CEBD) and corneal subepithelial nerve fiber density (CNFD) were measured and compared using confocal microscopy (Heidelberg Engineering, Germany). The differences in each variable were compared with the analysis of variance (ANOVA). A P value < 0.05 was considered significant for all comparisons. No statistically significant differences were found between patients under EGFRi treatment and the age-matched controls in the variables analyzed. When cases and controls were evaluated separately, the case group showed a significantly worse progression of signs (chemosis score, CFS, Schirmer's) as well as in terms of CEBD and CNFD (all P < 0.05). Systemic EGFRi may increase dry eye signs as well as decrease CEBD and CNFD. This study may help us to understand the true toxicity of EGFRi to the ocular surface. Il existe une inquiétude par rapport à la sécurité des médicaments inhibiteurs du récepteur du facteur de croissance épidermique par voie générale (EGFRi) en ce qui concerne la toxicité de la surface oculaire. Une étude prospective a été realisé pour évaluer cette toxicité. Des patients atteints d’un cancer de poumon ou côlon sous chimiothérapie de première intention ont été divisés en 2 groupes. Un premier groupe de 25 patients traités avec des EGFRi et 25 contrôles sans ce traitement. Un suivi d’un an a été réalisé avec 4 rendez-vous comparant des signes et des symptômes. On a utilisé les questionnaires SIDEQ, OSDI et VAS, le test d’Oxford, le test de Schirmer et une évaluation quantitative de chémosis et d’hyperémie conjonctivale. Avec la microscopie confocale (Heidelberg Engineering, Allemagne) on acomparé la densité basale cellulaire épitheliale cornéenne moyenne (CEBD) et la densité nerveuse sous-épithéliale (CNFD). Les différences ont été comparés avec l’analyse de la variance (ANOVA). Une p < 0,05 a été considérée significative pour les comparaisons. On n’a pas trouvé des différences significatives dans les variables analysées. Quand on a évalué les groupes séparément, les cas montrent une évolution moins favorable par rapportaux signes (chemosis, Oxford's et Schirmer) et au niveau de la CEBD et la CNFD (p < 0,05). Les EGFRi peuvent augmenter les signes de sécheresse oculaire et réduire la CEBD et la CNFD. Cet étude nous aide à éclaircir la toxicité de ces inhibiteurs au regard de la surface oculaire." @default.
