Penile cancer is rare, and few population-based studies have described changes in time trend. This study aims to determine whether there has been an evolution in incidence and survival of penile cancer over time in France.
Rates of age world-standardized incidence (ASRW) and net survival (NS) between 1989 and 2011 were calculated using data from 16 French cancer registries. Time trend incidence and survival analysis were confined to the eight registries operating throughout the full period. Log-linear Poisson regression analysis was used to estimate the average annual percentage change (AAPC) in incidence rates. The incidence rate for the most recent period was also calculated from all 16 cancer registries operating during 2009-2011. Human papillomavirus (HPV) exposure was deduced from the morphological code. NS was estimated using the Pohar-Perme estimator of the net cumulative rate.
No significant change in incidence was observed between 1989 and 2011 (AAPC: 0.08%; 95%CI: -1.01%; +1.17%). The incidence increased with age. The ASRW in 16 registries operating in 2009-2011 was 0.59 per 100,000 (95%CI: 0.50-0.68). The proportion of cases potentially linked to HPV was nearly 11% and did not change significantly over time. NS decreased with age but did not change over time (around 65% at 5 years).
Penile cancer remains rare in France, but survival is still low - probably because of delays in diagnosis and limited improvements in care. International clinical trials are needed to develop care recommendations based on an adequate level of evidence.
