Objective:
The decision to perform surgery in cases of spinal plasmacytoma (SP) is controversial. This study aimed to evaluate the reliability of the Spinal Instability Neoplastic Score (SINS) in evaluation of spinal instability in patients with SP.
Methods:
Clinical and radiological characteristics of 10 patients with SP were retrospectively evaluated. Age, sex, preoperative symptoms, duration of symptoms, pain score, American Spinal Injury Association score, and SINS were analyzed.
Results:
The 10 patients included 6 men and 4 women. Plasmacytoma was located in the sacrum in 1 patient, in the lumbar spine in 2 patients, in the thoracic spine in 6 patients, and in the cervical spine in 1 patient. Biopsy was performed in 2 patients, biopsy and vertebroplasty were performed in 2 patients, and biopsy and acute decompression and stabilization surgery were performed in 6 patients. SINS was <7 in 1 patient, 7-12 in 5 patients, and >12 in 4 patients. Two patients with a low SINS (<13) underwent only biopsy, and 2 patients underwent biopsy and vertebroplasty. Decompression and stabilization surgery was performed in 2 patients with SINS 7-12 and 4 patients with SINS >12.
Conclusions:
Decision making regarding augmentation, decompression, and stabilization in patients with SP is controversial. SINS may play a role during the decision-making process. Augmentation can be performed in patients with painful SPs with osteolytic changes with or without fracture (SINS <13). Decompression and stabilization surgery is the first-choice treatment in patients with SINS >12.
