Nonepithelial ovarian cancer - the current clinical practice in the Nordic countries. Survey from the surgical subcommittee of the Nordic society of gynecological oncology (NSGO).

Prospective clinical national research programs are sparse, and an enhanced cooperation in the Nordic countries toward development of a Nordic guideline and database is highly warranted and a prerequisite for future research, preferably in cooperation with the larger international groups.
