This is a retrospective analysis of 180 patients treated by combination of radical surgery and radiotherapy for invasive carcinoma of the cervix in stage IB and IIA. The influence of the following prognostic factors on the survival has been evaluated: the presence of pelvic lymph node metastases, histopathology of the tumor, the size of the primary tumor, presence of vascular space invasion and surgical margines. Nodal status has proved to be the most important prognostic factor: 91% of patients without pelvic lymph node metastases survived 5 years, 57% with up to two metastases and 36% with three and more metastases to the pelvic nodes. A significantly worse prognosis has also been observed in patients with adenocarcinoma of the cervix, and with the size of the tumor of more than 2 cm.
