RET and carcinoma: For example, only 1.3% of the total number of analyzed carcinomas demonstrated 5′/3′-end imbalance with a deltaCt >/=3; 152/169 (89.9%) tumors meeting this cut-off carried common RET rearrangements; however, only 152/185 (82.2%) NSCLCs with RET fusions had a deltaCt satisfying this cut-off (Table 1 and Table 3).
