abstract
OBJECTIVE:
The
aim of this epidemiological study was to describe the incidence,
mortality and survival of ovarian cancer (OC) in France, according to
age, period of diagnosis, and histological type.
METHODS:
Incidence
and mortality were estimated from 1980 to 2012 based on data in French
cancer registries and from the Centre for Epidemiology of Causes of
Death (CépiDc-Inserm) up to 2009. Net survival was estimated from
registry data using the Pohar-Perme method, on cases diagnosed between
1989 and 2010, with date of last follow-up set at 30 June 2013.
RESULTS:
In
2012, 4615 cases of OC were diagnosed in France, and 3140 women died
from OC. World population age-standardized incidence and mortality rates
declined by respectively 0.6% and 1.2% per year between 1980 and 2012.
Net survival at 5years increased slightly, from 40% for the period
1989-1993 to 45% for the period 2005-2010. Net survival varied
considerably according to histological type. Germ cell tumors had better
net survival at 10years (81%) compared to epithelial tumors (32%), sex
cord-stromal tumors (40%) and
tumors without biopsy (8%).
CONCLUSIONS:
Our
study shows a decline in incidence and mortality rates from ovarian
cancer in France between 1980 and 2012, but net survival remains poor
overall, and improved only slightly over the whole study period.
