The histology of ovarian cancer: worldwide distribution and implications for international survival comparisons (CONCORD-2).

ABSTRACT:

Objective

Ovarian cancers comprise several histologically distinct tumour groups with widely different prognosis. We aimed to describe the worldwide distribution of ovarian cancer histology and to understand what role this may play in international variation in survival.

Methods

The CONCORD programme is the largest population-based study of global trends in cancer survival. Data on 681,759 women diagnosed during 1995-2009 with cancer of the ovary, fallopian tube, peritoneum and retroperitonum in 51 countries were included. We categorised ovarian tumours into six histological groups, and explored the worldwide distribution of histology.

Results

During 2005-2009, type II epithelial tumours were the most common. The proportion was much higher in Oceania (73.1%), North Am
