| 内容記述 | On the basis of our ovarian cancer registration from 1983 through 1992, we analysed recent trends in ovarian cancer in Niigata Prefecture. The incidence of ovarian cancer was shown to be rising slightly year by year (p<0.01) by a non parametric test, owing primarily to an increase in malignant surface epithelialstromal tumors. However, sex cord/stromal tumors and germ cell tumors remained rare and almost stable in number of cases (p<0.05). We defined a high risk area as a significantly high standardized incidence rate (SIR) area, to which one village and one town were indicated. No high risk area was observed in cities. Among the areas researched, an area in Aikawa Town which was considered to be the highest risk area in Niigata Prefecture showed an age-adjusted incidence rate of 226.6 when calculated by the direct method, a figure 31 times higher than the prefectural rate. By the indirect method, also, a similar result of 197.8 was obtained. In the past 10 years, 10 cases of ovarian cancer have been detected in an area in Aikawa Town, including 9 cases of malignant epithelial-stromal tumors and 1 immature teratoma. All of the 10 patients as well as their parents were born and raised in this area. Furthermore, of the 168 women over 30 years of age in this area with cancer screening, 80% of both them and their parents had been born and raised in Aikawa Town or in this area. To investigate carcinogenic risk factors, a comparison was made as to the number of gravidity, parity, and age at menarche and natural menopause between 364 ovarian cancer cases from our registration, counting 817 cases in women over 30 years of age in Aikawa Town and 3340 controls also aged over 30 in Niigata City who had undergone uterine cancer examination in 1991 and had no ovarian tumor nor operative history. The number of gravidity and parity alone was significantly different between ovarian cancer cases and the control. The breakdown of the 364 patients with ovarian cancer by past history was as follows: 47 cases with sterility (12.9%), 22 cases with cystectomy of an ovarian tumor (6.0%), 9 with total hysterectomy (2.4%), 9 with tubal ligation (2.4%), 13 with endometrial or mammary or rectal cancer (3.6%), which remain to be answered with respect to the etiology and prophylaxis of ovarian cancer. We conclude that further investigation in high risk districts will elucidate these questions. | |||||
