Several possible mechanisms for the synergistic anti-tumour effects between
tumour necrosis factor alpha (TNF-alpha) and melphalan after isolated limb
perfusion (ILP) have been presented. We found a significant sixfold increa
se in melphalan tumour tissue concentration after ILP when TNF-alpha was ad
ded to the perfusate, which provides a straightforward explanation for the
observed synergism between melphalan and TNF-alpha in ILP. (C) 2000 Cancer
