[0034] A method for establishing a nasopharyngeal carcinoma distant metastasis prediction model proposed by the present invention, such as figure 1 Shown is the system structure of the prediction model for distant metastasis of nasopharyngeal carcinoma. The method for establishing the model specifically includes:
[0035] (1) By reading the digital images of pathological sections of nasopharyngeal carcinoma patients scanned completely (multiple ≥ 400 times, resolution ≥ 12000×12000), and manually or software Outline the tumor cell area (resolution ≥ 1000×1000), and at the same time use a large number of stored digital images of nasopharyngeal carcinoma tumor pathology sections with known metastasis information as a training set for deep learning algorithms;
[0036] (2) Cut the outlined tumor area, and use the gray threshold method and Otsu threshold method to filter the background of the cut digital image to eliminate noise and dirty data; then perform normalization processin...
