Nomogram construction
tumor, micropapillary bladder cancer
TUMOR, LYMPH NODE METASTASIS
Nomograms were established based on the above independent prognostic factors for predicting the 1-, 3-, 5-year CSS and OS (Fig. Nomograms predicting the 1-, 3-, 5-year CSS of micropapillary bladder cancer. I Each of the independent prognostic factors was given a point according to HR. The scores corresponding to independent prognostic factors were added to obtain the total score which is located onto the total points scale to obtain the probability of 1-, 3-, and 5- year CSS and OS. Nomograms can make individualized prediction based on patient information, improving the accuracy and efficiency of prediction. For example, if a 70-year old single patient was found no positive lymph node metastasis, the tumor size was 4 cm, and the AJCC stage was III after radical cystectomy, he would score 130 points, which means that this patient has approximately 86% possibility of cancer-special survival in the first year, approximately 62% possibility of cancer-special survival in the third year and approximately 52% possibility of cancer-special survival in the fifth year.
