Introduction: The decision of a surgical procedure and the surgical strategy are based on the life expectancies of the patients. The systems differ greatly in the parameters evaluated and in the result of the total score. Therefore, for the same patient, different survival periods can be calculated and contradictory treatment strategies suggested.
Objective: To evaluate patients with spinal metastases who underwent surgery, evaluating survival according to the SORG (Skeletal Oncology Research Group) Nomogram.
Materiales and Methods: Retrospective study, March 2017 to March 2019. 20 patients. Inclusion criteria: spinal metastases, with or without spinal compression. Evaluation parameters: the SORG Nomogram with probability of survival, at 30, 90 and 365 days, in the preoperative phase and the remote evaluation: survival to March 2020.
Results: 14 women and 6 men, average age: 67.9 years. Follow-up 6 to 36 months. Average final score: 222.4 points, which would be equivalent to a survival of 99% after a month, 78% after 3 months and 50% after a year.
Conclusion: In cancer patients with spinal metastases, the SORG nomogram would be useful to predict survival, especially at one year.
