Present Status and Issue of Cooperation of HBOC Clinical Practice in Niigata Prefecture
摘要
Niigata Prefecture is a heavy snowfall area facing the Sea of Japan, with a population of approximately 2.3 million. It spans about 330 km in length and is the fifth largest prefecture in Japan (Fig. 1). With approximately 1300 new cases of breast cancer and 100 new cases of ovarian cancer occurring annually, it is estimated that approximately 100 new cases of HBOC occur overall. Niigata Prefecture is vast and includes a remote island (Sado Island), making the need for collaboration and self-sufficiency within the prefecture itself regarding HBOC management greater than in other regions..
