AimThis study aims to investigate demographic data, survival rates, and the relationship of these rates with surgery in a large case series including multiple myeloma (MM) patients.MethodMM cases were analyzed retrospectively using the latest version of the SEER database published in April 2020. This version covers January 1975 to December 2017. Patients were classified according to gender, age, and race/ethnicity. Tumors were classified according to their localization, grade, year of diagnosis, and follow-up results.ResultsThere were 60,239 patients diagnosed with Plasma Cell Myeloma. While 670 patients (1.2%) were operated on, 43,976 patients (76.7%) did not indicate operation, and 12,670 patients (22.1%) could not be operated on despite the recommendation. The mean survival was 62 months in those without an indication for surgery, and 42 months in patients with an indication but could not be operated on, and the difference was significant (p = 0.001). The mean survival was 58 months in the operated patients, and 42 months in the patients who could not be operated on despite the indication, and the difference was significant (p = 0.001). There was no difference between those who did not indicate surgery and those who were operated on with an indication (p = 0.243).ConclusionIn multiple myeloma, the best prognosis is in the group of patients who received medical treatments without any indication for operation, while an indication for operation indicates a worse prognosis. A worse prognosis should be expected in patients who do not accept the operation or who cannot be operated on compared to the operated patients.
