Meningiomas that were treated with radiotherapy before resection had significant lower scores for SSTR1 (5.4 compared to 6.6, p = 0.0007) and SSTR5 (4.3 compared 4.9, p = 0.0340), while expression of SSTR2A, 3, and 4 were similar to tumor tissue that did not receive radiotherapy. This evidence concerns the gene SSTR1 and meningioma.
