OBJECTIVE
Our purpose was to evaluate the changing trends of the incidence and histopathology of female genital malignancies through the three time periods (1975-1984, 1985-1994 and 1995-2000). METHODS: A retrospective review was carried out of all the female genital malignancies with the exception of trophoblastic disease which reported to the Keimyung University Dongsan Medical Center between 1975 and 2000. RESULTS: For 26 years (1975-2000), 5,846 cases of the genital malignancies were registered. In the period from 1995 to 2000, the average frequency of cervical cancer was 73.5%, ovarian cancer followed with 15.6%, uterine corpus with 8.7%, vaginal cancer with 1.0%, vulvar cancer with 0.9%, tubal cancer with 0.1%. Third time period (1995-2000) comparing to others (1975-1984, 1985-1994), the frequency of cervical cancer was decreased (93.4% in 1975-1984, 86.0% in 1985-1994) and the incidence of corpus (1.6% in 1975-1984, 3.6% in 1985-1994) and ovarian cancer (2.4% in 1975-1984, 6.3% in 1985-1994) were increased. The most frequent histologic type of cervical cancer was squamous cell carcinoma, and followed by adenocarcinoma. Adenocarcinoma of the cervix showed a gradual increase in incidence (12.4% in 1995-2000, 5.0% in 1975-1984, 8.2% in 1985-1994). The peak age incidence of cervical cancer was noted between 40-49 years. Based on the FIGO staging system for cervical cancer, stage I was most frequent during last 6 years. According to invasiveness of the cervix, the frequency of cervical intraepithelial neoplasm was increased (62.8% in 1995-2000, 25.7% in 1975-1984, 38.4% in 1985-1994). Ovarian cancer was the second most common malignancy and gradually increased. The peak age was 50-59 years. According to histologic subtype, an epithelial ovarian tumor was most frequent. Corpus cancer was the third most common malignancy. The peak age was 50-59 years during the study period and endometrial cancer was most common. CONCLUSIONS: This study shows that the frequency of invasive cervical cancer was decreased whereas the incidence of endometrial cancer and ovarian cancer were increased. The frequency of cervical intraepithelial neoplasm was increased compared with invasive cervical cancer. |
