que les tumeurs diploïdes, suggérant qu’il existerait une
corrélation indirecte entre la ploïdie cellulaire et l’in-
dex de prolifération cellulaire. Cependant, selon
HOOFNAGLE [6] il n’existerait pas de corrélation entre
l’index de prolifération cellulaire et le stade TNM lors
de la découverte de la maladie. Enfin, bien que le taux
de survie à 3 ans soit supérieur pour les patients avec
une tumeur diploïde par rapport aux tumeurs aneu-
ploïdes, cette différence n’est pas statistiquement signi-
ficative.
CONCLUSION
1. Il existe une corrélation entre ploidie et degré de dif-
férentiation pour les tumeurs épidermoïdes du pénis.
2. Tous les carcinomes verruqueux sont diploïdes, ces
tumeurs ne donnant par ailleurs pas d’envahissement
lymphonodal.
3. Les tumeurs à index en ADN élevé semblent avoir
un risque métastatique plus important.
