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). The gene discussed is SSTR2; the disease is meningioma.
