title: Value of lymphography in Stage IB cancer of the uterine cervix.
abstract: In many neoplasms, lymphography is a reliable method with which lymph node metastases are demonstrated, but its accuracy in Stage IB cancer of the uterine cervix remains to be more firmly established. One hundred patients with Stage IB cancer of the uterine cervix underwent lymphography before radical hysterectomy with pelvic lymphadenectomy was contemplated. All the lymphographic findings were reviewed without knowledge of the pathologic parameters of the patients and were classified as being either positive (five cases), suspicious (15 cases), or negative (80 cases). The pathologic studies revealed lymph node metastases in 18 patients--in five with positive lymphographic findings, in three with suspicious findings, and in 10 with negative ones. The five true positive cases were compared to the 13 false negative or suspicious lymphographic results. It appears that the former have a greater number of involved lymph nodes and a greater mean size of the metastases. Thus, in Stage IB cancer of the uterine cervix, lymphography demonstrates an excellent specificity (100%) but a low sensitivity (27.8%).
