Abstract
- <bold>Aims: </bold>The aim of this prospective study is to evaluate prognostic significance of tumor volume determined by three-dimensional (3D) ultrasound scan in uterine cervix cancer patients treated by radiotherapy.<bold>Patients and Methods: </bold>A total of 67 patients of Stage IB2-IIIB were studied and analyzed. Cervical tumor volume was determined by 3D ultrasound scan. Two groups were made on the basis of volume on ultrasound scan (Group 1 <40 cc = 36 and Group 2 >40 cc = 31). Both groups received external beam radiotherapy (EBRT) and intracavitary radiation therapy (ICRT). Cisplatin 40 mg/m 2 every week was given concurrently with external irradiation. Tumor volumes were taken by 3D USG every week during EBRT, after each fraction of ICRT, and after 8 weeks of completion of treatment. Primary end point was disease-free survival (DFS), and secondary endpoints were 5-year survival and toxicities.<bold>Results: </bold>After 2 months of completion of treatment, 1 out of 36 patients of Group A was having residual and 7 out of 31 of Group B were having residual diseases (P = 0.034). DFS and 5-year survival were significantly different in the groups (log rank test P = 0.0014, hazard ratio (HR) =2.3622 95% confidence interval (CI) 1.3090-4.2625 and P = 0.0421, HR = 1.9274 95% CI 0.9998-3.7156, respectively).<bold>Conclusions: </bold>Ultrasound is a cheap, simple, and useful in predicting the outcome of treatment and DFS based on the tumor volume.
