Long term survival in women with borderline ovarian tumors: a population-based survey of borderline ovarian tumors in Sweden 1960-2007.

Research output: Contribution to journalArticle


Evaluation of incidence and survival of patients with borderline ovarian tumors in Sweden MATERIAL AND METHODS: All women diagnosed with borderline ovarian tumor in the Swedish Cancer Register 1960-2007 (n=6,252) combined with follow-up in the Swedish Death Registry to 1 July 2009 were included. Estimation of age-standardized relative survival rate according to time periods for diagnosis RESULTS: The incidence of borderline ovarian tumors increased during the study period, with a steep increase during the 1980-ies. The age standardized 5 year relative survival including all borderline tumors diagnosed 2000-2007 was 97% (95% confidence interval: 92-99%). In women age 64 or younger 10 year relative survival related to age at diagnosis of borderline tumors ranged from 95 to 98% and were 89% in women 65-74. In a multivariable analysis including age and decade of diagnosis relative survival for every decade increased. The 10-year relative survival in patients with mucinous and serous borderline tumors did not differ significantly (p=0.121).
