La Lettre du Cancérologue - volume X - n° 4 - juillet-août 2001
schémas actuels, encore trop toxiques et astreignants, sont sou-
vent non applicables. Le choix de la chimiothérapie
(LV5FU2 ? LV5FU2-cisplatine ? ECF ?) est conditionné par
l’âge, le terrain, l’état général, l’espoir de résécabilité, mais
aussi l’expérience du prescripteur. De nouveaux agents (irino-
técan, oxaliplatine, taxanes, prodrogues orales) et cibles théra-
peutiques ouvrent de nouvelles voies de recherche faisant
espérer un allongement de la durée de palliation. Disposant
maintenant de plusieurs molécules et associations potentielle-
ment efficaces (tableau V), des essais évaluant des stratégies
avec deux lignes thérapeutiques sont souhaitables, comme en
cas de cancer colique. Les progrès de la biologie moléculaire
dans la caractérisation des facteurs pronostiques ou de chimio-
sensibilité devraient permettre prochainement d’adapter le trai-
tement “à la carte” pour chaque type de cancer. La participa-
tion aux essais thérapeutiques reste, bien sûr, plus que jamais à
encourager. ■
