We retrospectively studied 26 patients with stage Ic or greater malign
ant germ cell tumors of the ovary. Sixteen of the 26 underwent fertili
ty-preserving treatment and 10 underwent total hystero-oophorectomy. T
here were 3 deaths in each group, but none among the stage Ic cases. T
he survival curves for stage II to IV disease did not significantly di
ffer in the two groups. Seven patients in the fertility-preserving gro
up were married, and had children. All patients in the hystero-oophore
ctomy group remained single except for one who was married before surg
ery. These results suggest that fertility-preserving treatment should
be offered even in advanced cases.
