Ultrasonographic follow-up of primary choroidal malignant melanoma after proton beam irradiation therapy.
The aim of this study is to evaluate the ultrasonographic aspects of primary choroidal malignant melanoma (PCMM) after proton beam irradiation therapy and the reliability of its ultrasonographic follow-up in a series of 10 patients. All patients were examined with standardized A and B scan ultrasonography before and after treatment with proton beam irradiation therapy. The follow-up was carried out at 1, 3, 5, 8 months and then every 6 months. The mean follow-up was 20 months (range 6-34 months). The thickness of the tumors was demonstrated to be decreased and the internal reflectivity to be enhanced in 9 out of 10 cases from 8 months after treatment till the end of the follow-up period. Histopathology confirmed in 1 eye enucleated 5 months after treatment that medium-low internal reflectivity coresponded with several areas of high cellularity and cellular mitosis. The results of our study indicate the reliability of standardized A and B scan echography in the follow-up of PCMM treated with proton beam irradiation therapy.
