Objectives: The purpose of this study is to investigate the accuracy
rates of tumor T-staging and the efficacy of methods used
at T-staging.
Patients and Methods: Forty-seven laryngeal carcinoma patients
(6 females, 41 males; mean age 57.9±9.8 years; range 38 to 81
years) who underwent surgery at Haydarpaşa Numune Education
and Research Hospital 2. Ear Nose Throat Clinic between March
2003 and June 2008 were included in the study. T-staging of the
tumors were separately determined according to their clinical
examination, computed tomography (CT) findings, and their correlation
between these methods. Staging according to histopathological
examination was accepted as real accurate staging. Rates of accurate
staging according to postoperative histopathological examination
results were evaluated under guidance of the literature.
Results: When their accuracy rates in determining histopathological
T-stages of tumors were compared, there were no significant differences
between the methods. The rates of accuracy in determining
histopathologic T-stage of tumors were 40% by clinical examination;
66% by CT; and 76% when both methods were used together. The
most successful results were obtained at the tumors of glottic region.
Among the patients whose tumors had been staged inaccurately
by clinical examination, 71% were underestimated while 29% were
overestimated. Underestimation and overestimation of stagings
were found to be 37% and 63%, respectively, with CT examination.
Conclusion: Success of staging increases when clinical examination
is used in together with CT. While there is a tendency
towards underestimation of T-stage when staging is done only
by means of clinical examination, this tendency is towards overestimation
when CT is used alone. Thus, combination of clinical
examination findings with CT is necessary for an accurate
T-staging of a laryngeal cancer.
