Özet

Introduction: Volumetric measurements of benign tumors enable surgeons to trace volume changes during follow-up periods. For a volumetric measurement technique to be applicable, it should be easy, rapid, and inexpensive and should carry a high interobserver reliability. We aimed to assess the interobserver reliability of a volumetric measurement technique using the Cavalier's principle of stereological methods. Materials and methods: The computerized tomography (CT) of 15 patients with a histopathologically confirmed diagnosis of enchondroma with variant tumor sizes and localizations was retrospectively reviewed for interobserver reliability evaluation of the volumetric stereological measurement with the Cavalier's principle, V = t x [((SU) x d)/SL]2 x Sigma P. Results: The volumes of the 15 tumors collected by the observers are demonstrated in Table 1. There was no statistical significance between the first and second observers (p = 0.000 and intraclass correlation coefficient = 0.970) and between the first and third observers (p = 0.000 and intraclass correlation coefficient = 0.981). No statistical significance was detected between the second and third observers (p = 0.000 and intraclass correlation coefficient = 0.976). Conclusion: The Cavalier's principle with the stereological technique using the CT scans is an easy, rapid, and inexpensive technique in volumetric evaluation of enchondromas with a trustable interobserver reliability.
