[Evaluation of tumor extension in invasive cancer of the uterine cervix. Diagnostic evaluation of cervix cancer].
Cancer of the uterine cervix accounts for approximately 30% of deaths from malignancies in gynecology and this rate has remained unchanged for more than 40 years. The most important prognostic factor is the extent of the disease at the beginning of treatment. There is, however, a discrepancy of some 50% between clinical and postoperative staging. The aim of this study was to evaluate different diagnostic investigations leading to the preoperative classification (FIGO) of 261 patients with cervical cancer. Data of presurgical clinical and radiological examinations were compared with postoperative histopathological findings. Rectovaginal palpation and computerized tomography (CAT) both showed a positive predictive value of 60%. The performance of CAT and lymphography in the diagnosis of lymph node metastasis was poor with positive predictive values of 36.3 and 20%, respectively. In the absence of parametrial infiltration on palpation, cystoscopy and rectoscopy are superfluous since they are always normal. Urography, because of the possibility to show the topographic anatomy of the urinary tract, was justified in all cases. The value of surgical staging and more recent techniques such as sonography and magnetic resonance is discussed.
