III. CONCLUSION
Les plantes et le régime ali-
mentaire ont des effets de
moins en moins discutables
sur le cancer de la prostate.
Concernant le PC SPES, son
action chez les patients atteints
de cancer de la prostate en hor-
mono-échappement lui confère
une place intéressante malgré
des effets secondaires non
négligeables et l’absence d’au-
torisation par la Food and Drug
Administration. Il faut souli-
gner qu’il n’existe pas d’étude-
randomisée sur cette thérapie
et que son prix (200 à 300 dol-
lars par mois) reste un frein à
son utilisation plus large en
Europe. Les interventions dié-
tétiques semblent pouvoir agir
sur le cancer de la prostate hor-
monosensible. L’action du régi-
me alimentaire et des supplé-
ments passe-t-elle uniquement
par la baisse de la testostéroné-
mie observée ou existe-t-il
d’autres mécanismes d’action ?
Des études complémentaires,
portant sur des groupes de
patients plus importants sont
nécessaires
