Microinvssive carcinoma of the uterine cervix(Stage la) is the earliest stage of squamous carcinoma and has a 98% of 5 year survival. This article analyzed the subjects of 81 patients, diagnosed to microinvasive carcinoma in the department of Obstetrics and Gynecology, Wonju college of Medicine. But only 71 cases were accepted in our study and l0 cases were rejected after preliminary review. The retrospective approach to the clinicopathologic study of microinvasive carcinoma of the cervix based on their chief complaint, clinical finding, cytology, histologic type, lymphouascular permeation, lymph node metastasis, residual tumor on hysterectomy specimen and their eorrelation etc. was taken from January 1981 to December, 1992. Many of the women were asymptomatic and had normal appearing cervices. Pap-smear contributed to the detection of microinvasive carcinoma. The histologic type of the microinvasive carcinoma was almost large cell non-keratinizing type, but no correlation with depth of invasion. A case of positive vaginal cuff was obeerved in a patient treated by simple hysterectomy. Lymphovascular permeation by tumor was observed more predominantly in patient with above than 3mm. There was no correlation with the residual tumor on hysterectomy specimen, lymphovascular permeation and invasion depfh of cancer. There was no surgery-related death in this series.
