[Color doppler ultrasonography of uterine vessels during radiotherapy of advanced cervix cancers].

In tumor vessels of 14 patients with an advanced squamous cell carcinoma of the cervix uteri, an increase of the resistant index (RI) and the pulsatility index (PI) of tumor vessels was found later than the decrease of the volume of the tumor. For the uterine arteries these indices remained unchanged for patients with a complete remission, while for patients with incomplete remission there was a decrease of RI and PI.
