Fratura na coluna vertebral por mieloma múltiplo: correlação entre sobrevida e índices de Tomita e Tokuhashi

A COMPARISON OF THE TOMITA AND TOKUHASHI SCORES IN SPINAL METASTASIS

ABSTRACT Objective To compare Tokuhashi and Tomita scores in patients with epidural spinal metastasis who underwent surgical treatment. Methods A retrospective evaluation of 103 patients with spinal metastasis and epidural compression who underwent surgical treatment. An analysis was performed of agreement between the survival rates observed in the study sample and the survival rate estimated by the Tomita and Tokuhashi scales. Results The overall accuracy was 39.03% for the Tomita scale and 61.75% for the Tokuhashi scale. Fair agreement (0.38 weighted Cohen’s Kappa coefficient) was observed between patient survival and the Tokuhashi score, and slight agreement (0.25 weighted Kappa coefficient) for the Tomita score. The agreement for both scales was higher for patients with less than six months’ survival, with general accuracy of 79.17% for the Tomita and 70.59% for the Tokuhashi scoring system. Conclusion There was fair and slight agreement between the Tokuhashi and Tomita scores with patient survival group. The agreement was higher for patients with less than six months’ survival. Level of evidence III; Comparative retrospective study.

ASSESSMENT OF SCORES IN DECISION MAKING IN METASTASES OF THE SPINE

Objective : The aim of this study is to assess the intra- and interobserver concordance of SINS, Harrington, Tokuhashi and Tomita scores among general orthopedic surgeons and spine surgeons with experience above 5 and 10 years in the evaluation of patients with spinal metastasis. Methods : Twenty cases of patients with metastatic lesion of the spine were presented to 10 examiners and the scores aforementioned have been applied. After six weeks, the cases were reintroduced in a different order and data were analyzed. Results : The intraobserver reliability showed better agreement in SINS score among examiners with less experience and Harrington and Tomita scores among those who had more than 10-year experience. The interobserver reliability of the examiners of the group with over 10-year experience showed higher precision when using these scores, especially Harrington and Tomita. The SINS score was the choice for daily practice and was able to modify the management more often. Conclusions : This study demonstrated that the use of predictive scores of instability, Harrington, and prognosis, Tomita, had a higher intra- and interobserver reliability particularly among spine surgeons with experience above 10 years.
