Expression rate in canine and feline meningioma was slightly higher than the detection rate in human studies, ranging between 62%–98% and 81%–100% for SSTR1 and SSTR2, respectively (Ahsan et al., 2019; Barresi et al., 2008; Oliveira Silva et al., 2015; Volante et al., 2007). This evidence concerns the gene SSTR1 and meningioma.
