Relative risk (RR value)
death, prostate cancer, pain
PRIMARY TUMOR, REGRESSION, PROSTATE CANCER
For each level of age, the risk of death increased by 3.170 times. Similarly, for each level of the spinal segment, the risk of death increased by 1.909 times, and for each level of primary tumor nature, the risk of death increased by 2.298 times.The prognostic index (PI) can be calculated according to the prognostic factors determined using the Cox regression model and has important clinical significance. The larger the PI, the worse the prognosis; the smaller the PI, the better the prognosis (PI = 1.154 × age + 0.832 × primary tumor + 0.647 × spinal segment). Typical cases are shown in Figs. Male patient, 64 years old, with well-differentiated prostate cancer in February after combined treatment, Back pain 2 weeks preoperative VAS score of 8.7. Male patient, 59 years old, well-differentiated prostate cancer after combined therapy for 1 year, back pain 8 months, preoperative VAS score of 8.5. Female patients, 4 years after radical resection of the right lung, L5PVP combined with
