Additionally, the OS analysis did not reveal any significant prognostic value of plasma beta-arrestin-1 levels, neither in lung cancer patients in general (P value (log-rank test) = 0.67) nor in lung ADC patients (P value (log-rank test) = 0.47) nor in lung SCC patients (P value (log-rank test) = 0.08). Here, ARRB1 is linked to lung carcinoma.
