title: Long term follow-up of patients with advanced prostatic cancer treated with nasal buserelin.
abstract: Sixty one men, with advanced prostatic cancer, were entered on a trial using a nasally administered gonadotropin-releasing hormone analogue agonist, buserelin, as first line treatment. This is the first trial to use intranasal buserelin without primary injections and without antiandrogens. No 'flare' phenomenon was observed. The only side effects were hot flashes (69%) and decreased libido (25%). The response rate of 82%, with a median response duration of 16 months, compares favourably to responses reported with orchidectomy or estrogens. Serum testosterone, FSH and LH were monitored at regular intervals. Mean serum testosterone baseline values of 15 nmol/L decreased to castrate levels, and remained low while patients were on study. It is concluded that intranasal buserelin is an effective, simple and safe method to achieve androgen deprivation and is an alternative to orchidectomy in the treatment of advanced prostatic cancer.
