To what extent do age, stage and treatment influence survival after invasive cervical cancer: a French population-based study.

Purpose: In an attempt to understand why cervical cancer (CC) survival is decreasing with diagnosis period among older women in France, this study aimed to estimate the effects of main prognostic factors on net survival in CC according to age.

Methods: French cancer registries databases were used to retrospectively analyze women diagnosed with CC in 2011-2012. Net survival was estimated with the Pohar-Perme method and prognostic factors (socio-demographic, clinical variables, stage at diagnosis, therapeutic management) were analyzed with Lambert and Royston's flexible parametric model.
