ƒ ABVD Introduced in 1975: ƒ Milan Randomized trial – advanced stage – ABVD was found superior

ƒ 6 cycles of ABVD ƒ 300mg/m2 Adriamycin – Tolerance is 450450--500500 mg/m2 IVP ABVD established

ƒ CALGB in US compared ABVD to MOPP to MOPP ABVD in advanced stage no radiation ƒ Canellos 2002 NEJM Type of chemotherapy

ƒ Stanford V introduced 1995 ƒ reported on for both early and advanced stage ƒ 8 or12 weeks of chemotherapy ƒ RRadiationadiation from 20 to 36 Gy

ƒ Excellent outcome ƒ LLowow toxicity Step 2: delete extensive radiation as sole modality
