Intense interest in advanced squamous cell cancers of the head and neck (SCC of H&N) has resulted from the recent progress made in tumor responses with chemotherapy and radiotherapy. Unfortunately, the response patterns and clinical outcome of such patients are not adequately predicted on an individual patient basis using clinical parameters or conventional morphology. The study of flow cytometrically determined cellular parameters in such tumors is therefore of interest, but is hindered by inadequate tumor preparative technology. The previous article (10) in this journal describes the use of a murine SCC tumor, LC12, which was employed for comparative testing and determination of optimum techniques of preparation for this tumor. This report describes the application of these techniques to 144 specimens of human SCC of H&N. The mean total yield for these specimens is 7.4 X 10(7) cells/g of tissue. The mean viable enzymatic yield (3.3 X 10(7) cells/g) was higher than the mean viable mechanical yield (2.0 X 10(7) cells/g) except when lymph nodes were the source of the specimen (5.4 X 10(7) cells/g). The mean dye exclusion viability from enzymatically dissociated specimens were above 90%. Significant aneuploidal subpopulation losses were evident in mechanically dissociated and enucleated specimens. 65% of the enzymatically dissociated specimens were successfully cultured with a mean cloning efficiency of 2.1 X 10(-3). Preparative techniques derived from comparative testing with a murine standard tumor have been successfully applied to 144 specimens of SCC of H&N with resultant high yields and excellent viability. Technical problems detected during the preliminary testing with LC12 were confirmed in the human tumors.
