The invention discloses a pCR prediction method based on multi-type medical data. The method includes the following steps that: clinical data, CT diagnosis reports and enteroscope images are obtainedfrom a medical department; an SVM is trained by using the clinical data, a BERT model is obtained by means of transfer learning training with the CT diagnosis reports, and a Faster-RCNN model is obtained by means of transfer learning training on the basis of the enteroscope images; and the clinical data, CT diagnosis report and enteroscope image of a patient to be predicted are inputted into the three trained models, predicted pCR probabilities p1, p2 and p3 are obtained, the predicted pCR probabilities p1, p2 and p3 are fused, a final predicted pCR probability p is obtained, and if p is greater than a set threshold T, it is predicted that the patient has pCR. According to the method, the Faster-RCNN network is used; a tumor ROI can be automatically generated; a whole process does not needmanual intervention; and prediction efficiency is improved. The neural network is used for representation learning; manual setting and feature selection are not needed; and therefore, the accuracy and efficiency of prediction are improved. PCR prediction is carried out by combining the clinical data and the CT diagnosis report of the patient, so that prediction accuracy is improved.
