Denis A. Hughese turned out to be more quantitative than qualitative (Markert, 1982; Nicolson, 1984a). Even more damaging to a simple “exploitable difference” approach is evidence, now accumulating, that significant differences may exist between malignant cells even within the same tumor. These differences may be
