BACKGROUND: This study was designed to evaluate radiation-induced changes in tumor blood flow by color Doppler ultrasonography. METHODS: Color Doppler examination was performed on 14 patients with advanced cervical carcinoma treated with external radiotherapy. The total dose of radiation varied from 30 to 65 Gy and was given as 1.9 Gy daily fractions, 5 days/week. Tumor vascularity and blood flow impedance were measured by one pretreatment and five follow-up examinations. RESULTS: At the baseline examination, 11 of 14 patients had very low tumor blood flow impedance (< 0.70). Radiotherapy caused a significant decrease in tumor vascularity (P = 0.0001) and in presence of very low blood flow impedance. The decrease of tumor vascularity during the treatment was associated with better outcome, whereas persistence of excessive vascularity or of vessels with low blood flow impedance at the end of radiation was associated with modest therapeutic response. Eight of 10 patients with increased tumor vascularity at the end of radiation needed further treatment or died of disease. Only one of four patients with normal vasculature at the end of radiotherapy needed further treatment and all four were clinically disease free during the follow-up (mean, 13 months; range, 6-26 months). CONCLUSIONS: These results suggest that color Doppler ultrasonography may be useful in early assessment of therapeutic response during radiotherapy and in for planning individualized treatment schedules. |
