The present study was a prospective observational study to determine the effect of cinacalcet treatment on <jats:styled-content style=\"fixed-case\">PTG<\/jats:styled-content> volume and serum biochemical parameters in 60 patients with renal <jats:styled-content style=\"fixed-case\">SHPT<\/jats:styled-content>, already treated with intravenous vitamin <jats:styled-content style=\"fixed-case\">D<\/jats:styled-content> receptor activator (<jats:styled-content style=\"fixed-case\">VDRA<\/jats:styled-content>). Measurement of biochemical parameters and <jats:styled-content style=\"fixed-case\">PTG<\/jats:styled-content> volumes were performed periodically, which were analyzed by stratification into tertiles across the baseline parathyroid hormone (<jats:styled-content style=\"fixed-case\">PTH<\/jats:styled-content>) level or <jats:styled-content style=\"fixed-case\">PTG<\/jats:styled-content> volume. We also determined the factors that can estimate the changes in <jats:styled-content style=\"fixed-case\">PTG<\/jats:styled-content> volume and the achievement of the target <jats:styled-content style=\"fixed-case\">PTH<\/jats:styled-content> range by multivariable analyses. Two years of cinacalcet treatment significantly decreased the serum levels of <jats:styled-content style=\"fixed-case\">PTH<\/jats:styled-content>, calcium, and phosphate, followed by the improvement of achieving the target ranges for these parameters recommended by the <jats:styled-content style=\"fixed-case\">J<\/jats:styled-content>apanese Society for Dialysis Therapy. Cinacalcet decreased the maximal and total <jats:styled-content style=\"fixed-case\">PTG<\/jats:styled-content> volume by about 30%, and also decreased the serum <jats:styled-content style=\"fixed-case\">PTH<\/jats:styled-content> level independent of the baseline serum <jats:styled-content style=\"fixed-case\">PTH<\/jats:styled-content> level and <jats:styled-content style=\"fixed-case\">PTG<\/jats:styled-content> volume. Ten out of 60 patients showed 30% increase in maximal <jats:styled-content style=\"fixed-case\">PTG<\/jats:styled-content> after 2 years. Multivariable analysis showed that patients with nodular <jats:styled-content style=\"fixed-case\">PTG<\/jats:styled-content> at baseline and patients with higher serum calcium and <jats:styled-content style=\"fixed-case\">PTH<\/jats:styled-content> levels at 1 year were likely to exceed the target range of <jats:styled-content style=\"fixed-case\">PTH<\/jats:styled-content> at two years. In conclusion, cinacalcet treatment with intravenous <jats:styled-content style=\"fixed-case\">VDRA<\/jats:styled-content> therapy decreased both <jats:styled-content style=\"fixed-case\">PTG<\/jats:styled-content> volume and serum intact <jats:styled-content style=\"fixed-case\">PTH<\/jats:styled-content> level, irrespective of the pretreatment
