In this work, records of 405 cases of malignant ovarian tumors experienced in the last five years were collected with the cooperation of 21 institutions in the Kinki region. It is true that there has been an increase in the incidence of ovarian cancer recently in Japan and treatment results are still not satisfactory, but it was evident from this investigation that the results of treatment of this disease in the Kinki region is gradually improving.
However, there are still no effective methods for the early diagnosis of ovarian cancer and it is necessary to stress that women should undergo periodic gynecological examinations in parallel with tests for uterine cancer.
