[Adjuvant contact radiotherapy for conjunctival malignancies: Preliminary results of a series of 14 patients treated with the Papillon 50 machine]. / Radiothérapie de contact adjuvante des tumeurs malignes de la conjonctive : résultats préliminaires d'une série de 14 patients traités avec l'appareil Papillon 50.

PURPOSE: To evaluate the results of an adjuvant contact irradiation using 50kV photons after resection of conjunctival malignancies. MATERIALS AND METHOD: From 2012 to 2014, 14 patients (male: nine; female: five) have been treated by contact irradiation after resection of a malignant tumor of the conjunctiva (melanoma: five patients; malignant fibrous histiocytoma: one patient; carcinoma: eight patients) The treatment was performed using the Papillon 50 machine (Ariane). Three to four sessions were delivered, each giving a dose of 10Gy. The median follow-up in survivors was 33 months. RESULTS: The tolerance was good. A cataract was seen in one patient, and a moderate eye dryness in one. There was no corneal ulcer. One patient died of intercurrent disease. One patient with carcinoma recurred locally. CONCLUSION: Adjuvant contact radiotherapy provides a good local control after resection of conjunctival malignancies (melanoma, malignant histiocytofibroma, carcinoma). Thanks to its precision, this technique is well tolerated with a low rate of complications. Furthermore, it is delivered on an ambulatory basis.
