CEACAM5 and cancer: Researchers have previously discussed the feasibility of incorporating blood test with routine image scan to improve early cancer screening/diagnosis performance and pulmonary nodule classification.[18, 23] We constructed a tri modal model integrated SMFs, tumor marker CEA, and Image‐AI via RF classifier (MPI‐RF), which is more robust and accurate for nodule risk stratification than dual modal MP‐NN and single modal Image‐AI (Figure 4).
