Although we investigated various parameters such as length of storage of tumors before freezing and desirability of autopsy versus surgically obtained human tumors in our initial reports of the immunofluorescent tumor imprint technique4,7 we use only surgically obtained specimens which are frozen and/or imprinted within one to two hours of excision. We reported4 that autopsy material was less desirable than surgical specimens and, of course, agree with Drs. Beck and Rowell that autolyzed tissue should not be used.
2. The fact that different types of tumors are
