摘要: Abstract Purpose: To investigate the value of CT-derived tumor parameters as predictor local and regional outcome tonsillar squamous cell carcinoma treated by definitive radiation therapy. Methods Materials: The pretreatment CT studies 112 patients with were reviewed. After redigitizing films, primary nodal volume was calculated summation-of-areas technique. aspect graded using a 3-point scale (homogenous, inhomogeneous, necrotic). Mean follow-up time 33 months. Actuarial statistical analysis done for each covariates; multivariate performed Cox's proportional hazards model. Results: In actuarial analysis, CT-determined significantly correlated recurrence rate ( p = 0.1). T N categories independent predictors outcomes, respectively. Conclusion: Compared to other head-and-neck sites, have only marginal predictive regarding after therapy in cancer.
