The major findings included that (1) CD147 expression was correlated with lung adenocarcinoma tumor differentiation and metastasis, (2) CD147 expression predicted a worse clinical outcome in postoperative lung adenocarcinoma patients, (3) the SUVmax was correlated with the CD147 expression of lung adenocarcinoma, (4) SUVmax was the primary predictor for the CD147-positive lung adenocarcinoma, and (5) The cutoff value of the SUVmax at 9.77 provided a reliable specificity and sensitivity for predicting the CD147-positive lung adenocarcinoma. The gene discussed is BSG; the disease is lung adenocarcinoma.
