so the next point to look at is Expression of Trop2 .... the Target for the $6 billion Mab ....
TROP2 expression in NSCLC
Immunohistochemical studies in 100 AdC samples revealed no expression (total score 0) in 53 (53.0%), weak expression (total score 1-4) in 24 (24.0%), moderate expression (total score 6 and 8) in 14 (14.0%), and strong expression (total score 9 and 12) in nine (9.0%). Thus, according to the aforementioned criteria, TROP2 was overexpressed in 23 (23.0%) of the AdC cases (Figure 3). In the 64 SCC cases, seven (10.9%) showed a lack of expression, 16 (40.6%) showed weak expression, 15 (23.4%) showed moderate expression, and 26 (32.9%) showed strong expression. TROP2 overexpression was noted in 41 (64.1%) of the SCC cases (Figure 3). TROP2 overexpression was significantly more frequent in SCC (P < 0.01) (Table 3).
