1977년부터 1984년 6월까지 연세대학교 의과대학 부속 세브란스병원에 내원한 170명의 자궁경부암환자를 대상으로 임파조영술의 진단정확도 및 임파조영술소견이 환자의 예후에 미치는 영향에 관해서 연구하였으며 그 결과는 다음과 같다. 1. 임파조영술의 진단정확도는 감수성 50%, 특이성 78.9%, 양성예측도 27.3%, 음성예측도 90.9%였다. 2. 기별 임파조영술 소견의 분포는 기가 증가할수록 그 양성율이 높았다. 3. 임파조영술 소견에 따른 환자의 예후는 2기 및 3기에서 각각 임파조영술 음성인 군이 임파조영술 양성(의양성 포함)인 군보다 통계학적으로 의의있게 무병생존율이 높았다.

The lymphographic accuracy in the diagnosis of metastasis was analysed in 170 patients with cancer of the uterine cervix. All the lymphographic findings were reviewed without knowledge of the pathologic parameters of the patients and were classified as being either positive, suspicious or negative. Pelvic lymphadenectomy was performed in 44 patients. The sensitivity of the lymphographic diagnosis was 50% and the specificity 78.9%. The predictive value of a positive test was only 27.3%, but the predictive value of a negative test 90.9%. The incidence of lymphographically proven metastasis(including suspicious cases) was 25% in stage 1, 38.5% in stage 2, 45.7% in stage 3 and 100% in stage 4 cervical cancer patients. The disease-free survival of cancer of the uterine cervix was estimated in 110 patients In stage 2 and 3 carcinoma, the disease-free survival of patients with negative lymphography was statistically significantly higher than that of patients with positive and suspicious lymphography.
