[Role of X-ray computed tomography in the evaluation of prognosis of cervical carcinoma].
In 129 patients with cervical cancer, CT findings before treatment were analysed on the basis of the outcome during a 5 year follow-up period (75 survivals, and 54 deaths). 1) The incidence of each CT finding in the two groups was; (1) enlargement of the uterine cervix: 40.0% in survivals, 64.8% in deaths, (2) low density area in the cervix: 18.7%, 37.0%, (3) necrotic cavity: 4.0%, 33.3%, (4) pyometra: 8.0%, 31.5%, (5) irregular and indistinct margin of the cervix: 2.7%, 51.9%, (6) abnormal image of parametrium: 25.3%, 87.0%, (7) extension to the vagina: 2.7%, 37.0%, (8) extension toward the bladder: 8.0%, 57.4%, and (9) enlarged lymph node: 0%, 27.8%. 2) CT scores obtained by multivariate analysis for prognostic discrimination of cervical cancer were (1) + 1, (2) - 1, (3) + 1, (4) - 3, (5) + 25, (6) type B + 29, C + 25, D + 10, (7) + 2, (8) grade I + 12, II + 7, III + 20, and (9) + 18, respectively. The discrimination ratio for the prognosis of cervical cancer was 82.9%. 3) The score obtained by multivariate analysis showed significant increases according with the stage. Even in the same stage, there were significant differences between the scores for survivals and deaths (stage II: p less than 0.01, stage III: p less than 0.05). The survival period in the poor prognosis group was correlated with the score, especially in the cases treated with radiotherapy (r = -0.54, p less than 0.01).
