Abstract/full free access: Endometriosis-associated ovarian cancer: A ten-year cohort study of women living in the Estrie Region of Quebec, Canada

excerpts of interest:

"The first interesting results in our study were the constant increase of the number ovarian cancer since 1997 to 2006. This increase is not supported by literature and should attract attention. Other studies should confirm if this increase is a geographically widespread or localized phenomenon."

"Also, it is known that prevalence of ENDO (in our region as in literature) is probably an under-estimation since an unknown proportion of women suffering of ENDO do not consult for their symptoms."
"The earlier manifestation (reference article ENDO in OC presents ~5yrs earlier) of OC has serious consequences..."
"Our findings are consistent with other studies supporting the predominance of
endometrioid and clear-cell types of ovarian cancer-associated endometriosis."

"Conclusion:
Our findings highlight that the number of cases of ovarian cancer is constantly increasing in the last ten years and that endometriosis represents a serious risk factor which accelerates its apparition by about 5.5 years."
