Figure 4From: Expression of Notch-1 and its clinical significance in different histological subtypes of human lung adenocarcinomaExpression of Notch-1 in different histopathological subtypes of lung adenocarcinoma. 17 APA patients (38.6%), 9 PPA patients (45.0%) and 7 other subtypes of patients (58.3%) were confirmed as positive (arrows), most SPA patients were confirmed as negative (P = 0.021), suggesting that immunostaining of Notch-1 in LAD tissues could be helpful for differentiating SPA from other histological subtypes.
