There have been considerable recent advances in our understanding of the origins of ovarian carcinoma. In particular, the evidence that many ovarian serous carcinomas arise from Fallopian tube epithelium may alter clinical practice. This symposium will bring delegates up to date through discussion of recent clinic-pathologic and molecular data on serous tumors and their implications for surgical and pathologic practice. This will be followed in 2013 by a symposium on other epithelial ovarian tumors, particularly clear cell and endometrioid carcinomas.
