Abstract
A potential application of the human tumor stem cell colony assay is to guide Phase II clinical investigations by identifying classes of tumors (or individual patients) which are sensitive in vitro to a new antitumor compound. We have tested human tumor stem cells from 140 tumor biopsies representing 20 different tumor types for chemosensitivity to the Phase II drug 4'-(9-acridinylamino)methanesulfon-m-anisidide. In vitro sensitivity was defined as a reduction in the number of tumor colony-forming cells to 30% of the control or less after a 1-hr exposure to one-tenth of the pharmacologically achievable plasma concentration of 4'-(9-acridinylamino)methanesulfon-m-anisidide. In vitro sensitivity was found in 29 cases: non-Hodgkin's lymphoma (2 of 2); cervical carcinoma (1 of 1); sarcoma (3 of 6); neuroblastoma (1 of 2); acute myelogenous leukemia (6 of 16); chronic myelogenous leukemia (1 of 3); melanoma (8 of 34); uterine carcinoma (1 of 5); lung carcinoma (1 of 9); ovarian carcinoma (4 of 36); and breast carcinoma (1 of 11). Prospective in vitro-in vivo correlations in eight patients with various tumor types showed that three of three patients sensitive in vitro to 4'-(9-acridinylamino)methanesulfon-m-anisidide responded in vivo, while five of five patients resistant in vitro had no clinical response. The results provide support for further evaluation of the utility of the human tumor stem cell colony assay for targeting Phase II clinical trials.
