The tumor cells were aspirated from metastatic lesions both prior to treatment and twice weekly after the administration of chemotherapeutic agents. Morphologic observation of tumor cells was done with a light microscope after Riu's staining. The nuclear area was measured with a Mini- magiscan. The nuclear DNA content of aspirated tumor cells was measured with a scanning microdensitometer after the modified Feulgen reaction. The cell population in the cell cycle was estimated with a cumulated percentage scale from the DNA histogram. Marked cytolysis with enlarged nuclei of the remaining cells and cell cycle perturbation occurred within one week after initiation of chemotherapy. There was a decrease in the G1 cell population (from 53.7 ± 10.0% to 12.7 ± 3.5%) and an increase in cells in the G2 phase (from 27.0 ± 8.7% to 68.3 ± 5.6%), which corresponded to the cells with enlarged nuclei (50.4% to 68.7% increase) after chemotherapy. The proportion of cells in S phase was slightly increased (from 19.3 ± 4.1% to 20.0 ± 3.7%). The degree of cell cycle perturbation correlated well with the cytomorphologic changes during chemotherapy. |
