VEGA HERNANDEZ, Manuel I et al. Experience of the first application of HDR brachytherapy in nasopharynx. Rev cubana med [online]. 2006, vol.45, n.4. ISSN 0034-7523.

A research was made by applying boost on the area of the nasopharynx relapse with high dose rate (HDR) in a diagnosis of nasopharynx carcinoma previously treated with telecobalt therapy, at a dose of 70 Gy. There was persistence of the injury. Three sessions were planned, with consecutive fractions of 6.5 Gy in 15 days, with optimization, using a personal mould of autopolymerizable acrylic. The successful possibility to apply the high rate modern brachytherapy was reaffirmed, as a treatment complementary to teletherapy in case of persistence or relapse. A MicroSelectron HDR equipment was used
