title: [Volumetric and structural changes of prostatic carcinoma under hormonal treatment].
abstract: The evolution of the ultrasonographic images of 25 patients with advanced carcinoma of the prostate receiving antiandrogen (cyproterone acetate) and LH-RH analogue therapy were studied. Thirteen patients were on daily LH-RH analogue therapy while the remaining patients received a monthly depot dose. At 6 months, the ultrasound follow-up revealed a 20.4% reduction of the transverse and a 19.8% reduction of the anteroposterior diameter for the first patient group. Similar results were observed for the second group comprised of 12 patients who received depot therapy; a mean reduction of the diameters of 119.9% and 18.7%, respectively. At 6 months, 66% of the patients in the first group and 59% of the second group showed an improvement of ultrasound patterns. Infiltration of the seminal vesicles improved for both groups, 41% and 38% of patients, respectively. However, at 12 months this rose to 50% improvement for the group on the daily treatment regimen. The follow-up data after 6 months are as yet unavailable for the group on depot therapy. Transrectal ultrasound is an easy, reproducible method that is very useful in the follow-up of patients with advanced cancer of the prostate receiving hormone therapy.
