"....The Gynecology Tumour Group of our institution has elected to continue to advise the use of CRT in women with stage Ic and II endometrioid and mucinous lesions, and all stage I and II clear cell disease, on the basis of these data and a recently published analysis of histotype-specific outcomes [32]. However, RT will be targeted to the pelvis, with consideration of extending the field to include paraaortic nodes if stage IIc (given the higher rate of occult nodal involvement reported for this stage [26]). RT will be dropped from our prescription for those with serous tumors.

Our findings also bring into question the nonselective surgical and CT approaches that have characterized ovarian cancer care and are of potential clinical importance for those with other tumors, which have been collectively defined by presumed organ of origin rather than underlying biological features"
