PAAD patients with high expression levels of ITGA3 (HR = 1.8, logrank p = 0.0072), ITGB1 (HR = 1.6, logrank p = 0.029), ITGB5 (HR = 1.6, logrank p = 0.032), ITGB6 (HR = 1.6, logrank p = 0.025), LAMA3 (HR = 2.1, logrank p = 0.00031), and CD9 (HR = 2.3, logrank p = 0.00012) had a worse prognosis compared with patients who had low ITGA3 expression (Figure 5). Here, CD9 is linked to pancreatic adenocarcinoma.
