The pathological study on the growth of the implanted tumor and host response indicated that the assay had to be done by four-day assay. The analysis of the isotope incorporation into the implanted tumor supported this results. As determination of tumor sensitivity by the microscopic measurement showed the large standard deviation, the DNA and protein content was determined for the evaluation of sensitivity by percent inhibition of the DNA/protein content (％DNA/protein).
Ninety five fresh tumor specimens were examined and evaluated by relative variation of the calculated tumor weight (⊿TW/TW0), while 64 specimens by ％DNA/protein. The evaluability rates using ⊿TW/TW0 and ％DNA/protein were 84.2％ and 87.5％, respectively. All over predictive accuracy between the clinical responses and the results of the assay evaluated by ⊿TW/TW0 was 78.6％, while 81.8％ was obtained by ％DNA/protein.
From these results, the potential utility of SRC assay examined on 4 day for deteminating chemosensitivity by ％DNA/protein seems to be benefical for clinical use.
