• Trattamento neoadiuvante delle metastasi
epatiche resecabili
• Trattamento neoadiuvante delle metastasi
epatiche non resecabili
• Trattamento adiuvante post-resettivo
• Trattamento delle metastasi epatiche sincrone da
cancro del retto
• Trattamento delle metastasi epatiche con
“minima” malattia extraepatica

Metastatic colon cancer Liver-only Disease:
Post Resection Treatment
D. Haller, D. Cunningam, D.J. Kerr 25/9/02
Trattamento adiuvante post-resettivo
• Necessario in ogni paziente resecato ?
• Dopo CT neoadiuvante sistemica ?
• Sola terapia sistemica ?
• Alternanza di CT sistemica di ultima
generazione / CT i.a. meno tossica (5-FU) ?
Terapia
sistemica
CT sistemica con schedule
basate sul 5-FU sembra
poter dare beneficio
ma le casistiche sono troppo
limitate per dare risultati
significativi

Conclusioni
Le metastasi epatiche non sono tutte
uguali . . . . e neppure i pazienti . . . . .e
neppure i medici
Indispensabile la valutazione
multidisciplinare di ogni caso
Studio organico delle caratteristiche
biologiche e di quelle cliniche
