Clinical and histopathological studies were made on 202 cases of malignancy of cervix, that were visited to the Department of Obstetrics and Gynecology, Yeungnam University Hospital, during 5 years from 1983 to 1987. The results were summarized as follows. 1. Malignancies of the uterine cervix were 10% of total female malignancies. 2. Among 202 cases, 195 cases (96.5%) were squamous cell carcinoma, in which 60 cases (30.0%) of carcinoma in situ, 9 cases (4%) of microinvasive, and 126 cases (62.5%) of invasive carcinoma were included. 3. The average age of the patients with squamous cell carcinoma was 49.4 years old; In case of carcinoma in situ, it was 43.8, microinvasive, 40.0, invasive 52.1 years old. 4. Clinical symptoms of the patient with squamous cell carcinoma in order of frequency were as follows; vaginal bleeding (47.5%), abnormal cytology (15.4%), and abnormal vaginal discharge (9.4%). 5. Duration of the chief complaints was most commonly less than 6 months (73.2%), and the average duration was 3.8 months. 6. The most common age of marriage was between 19 to 22 years old (46.5%).

The subdivision of 126 cases of invasive carcinoma was made according to FIGO stage classification, stage I, 40 cases (31.8%), stage II, 54 cases(42.9%), stage III, 11 cases (8.7%), and stage IV, 8 cases (6.3%). 9. The histologic subtypes of invasive squamous cell carcinoma were distributed as follows; large cell keratinizing type, 25 cases (19.8%), large cell nonkeratinizing type, 101 cases (80.2%). 10. In the cytologic diagnosis, class I was 2 cases (1.9%), class II was 16 cases (15.1%), class III was 33 cases (31.1%), class IV was 31 cases (29.3%), class V was 24 cases (24.6%). 11.

AbstractAbstract PDF
The frozen section technique is a means of intraoperative pathological diagnosis, and a procedure of great value to the surgeon. This method should be accurate, rapid and reliable. This method serves useful purposes, such as determining the presence of tumor, its type (especially whether it is benign or malignant), the adequacy of a biopsy of a suspected lesion, and the conditions of the surgical margins. But, it bears many disadvantages, the most of which is the danger of incorrect diagnosis. We studied the indications, the limitations, and the accuracy of the frozen section method and the materials studies was total of frozen section diagnosis of 809 cases was 98.1% with 0.5% of false negative, 0% of false positive 0.5% of incorrect histological diagnosis or grading errors, and 0.9% of deferred cases. The tissues submitted were lymph node, gastrointestinal tract, skin subcutaneous tissues in decreasing oder of frequency. The false positive case is not present, while the false negative cases were 4.
