Abstract

A method of treating cancer or inhibiting metastasis in a subject by increasing intratumoral extracellular pH is presented. The method includes administering to the subject a therapeutically effective amount of a buffer having a pKa greater than 6.1. In an advantageous embodiment the pKa of the buffer is about 7.0. Examples of buffers for increasing extracellular pH include NaHCO, 2-imidazole-1-yl-3-ethoxycarbonylpropionic acid (IEPA), cholamine chloride, N,N-Bis(2-hydroxyethyl)-2-aminoethanesulfonic acid (BES), N-Tris(hydroxymethyl)methyl-2-aminoethanesulfonic acid (TES) and 4-(2-Hydroxyethyl)piperazine-1-ethanesulfonic acid (HEPES). The method can further include the step of pretreating with one or more chemotherapeutic agents.
