    Abstract:
    Fifty-two cases of carcinoma in situ (CIS) of the uterine cervix were examined histopathologically and compared with seventeen cases of microinvasive carcinoma of the uterine cervix (restricted to the general rules for clinical and pathological management of uterine cervical cancer of the Japan Society of Obstetrics and Gynecology) in order to investigate the influence of the patient's age on the intraepithelial extension of CIS. The results were summarized as follows. 1. There was a positive correlation between circular spread and longitudinal spread of the lesion in CIS cases. 2. There was a positive correlation between circular spread and the depth of gland involvement of the lesion in CIS cases. 3. Circular spread of the lesion in microinvasive carcinoma cases was significantly more extensive than that in CIS cases. 4. Circular spread of the lesion in microinvasive carcinoma at menopause was significantly more extensive than that in microinvasive carcinoma at sexual maturity. These results suggest that CIS has intraepithelial extensibility, and that in CIS at sexual maturity there is a higher risk of invading stroma when circular spread of the lesion becomes greater than one fourth of the whole circle in the cervix, whereas CIS at menopause is more likely to invade the stroma when the circular spread of the lesion becomes greater than half of the whole circle in the cervix. In this respect we can find the influence of the patient's age on the biological behavior of CIS of the uterine cervix.
