Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] The present invention establishes a relevant database by analyzing relevant clinicopathological data of patients with newly diagnosed prostate cancer, and uses R statistical software in the database to analyze clinicopathological data variables related to bone metastasis by using Logistic multifactor regression model, and screens out relevant predictive variables and calculate the model coefficients for the predictor variables. In the R statistical software, the design package was used to draw the corresponding nomogram for predicting the risk of bone metastasis according to the coefficients of the Logistic regression model.

[0030] The following data are relevant clinicopathological data of patients with newly diagnosed prostate cancer, including the patient's age at the time of diagnosis, alkaline phosphatase value, prostate specific antigen (...

Abstract

The invention discloses a device for predicting the bone metastasis risk of newly-diagnosed prostate cancer. According to the device, the risk of bone metastasis is predicted, bone scanning is carried out on patients with high bone metastasis risk and the overuse of the bone scanning is avoided under the condition of not increasing missed diagnosis. The technical scheme provided by the invention is that the device comprises a storage module, four input modules, a processing module and an output module, wherein four input slots are formed in the storage module and are a slot with fixed length, a first slot for sliding, a second slot for sliding and a third slot for sliding respectively; the four input modules are a clinical stage input module placed in the slot with the fixed length, a Gleason scoring input module placed in the first slot for sliding, a PSA (Prostate-Specific Antigen) value input module placed in the second slot for sliding and an age input module placed in the third slot for sliding; the processing module is used for adjusting the positions of the four input modules in the input slots of the storage module to obtain an output locus; and the output module is provided with a staff gauge for predicting a risk value of the bone metastasis, and a corresponding locus of the output locus on the staff gauge is a predicted risk value.

Description

technical field [0001] The invention relates to a disease prediction device, in particular to a device for predicting the risk of bone metastasis in patients with newly diagnosed prostate cancer. Background technique [0002] Bone scan has high sensitivity in diagnosing bone metastasis of prostate cancer, but there are obvious differences in the applicable indications of bone scan between China and the West. European and American guidelines do not recommend bone scans for newly diagnosed prostate cancer patients, which is contrary to the current guidelines in China. At present, many studies have shown that PSA, clinical stage and Gleason score are independent predictors of bone metastasis of prostate cancer. However, with these indicators, we can only preliminarily judge whether bone metastasis will occur in prostate cancer, and we cannot make a more accurate judgment on the status of bone metastasis by integrating the predictive value of each indicator. [0003] At presen...
