title: [Effects of 5'-DFUR against BALB/c retroperitoneal sarcoma with spontaneous liver metastases].
abstract: A permanent cell line, termed LMFS (liver metastasis from sarcoma) was established in vivo and in vitro from a spontaneously occurring murine retroperitoneal tumor of BALB/c mouse origin. After a subcutaneous injection of more than 1 x 10(5) cells in the dorsal side of mice, the LMFS cells proliferated at the inoculation site (100% take) and induced metastatic nodules spontaneously in the liver but not in the lung. The antitumor effects of 5'-DFUR against the LM FS tumor were examined. Mice with the LMFS tumor were given 5'-DFUR (0, 0.75, 1.5, 3.0 mM/kg) per os for 7 days from day 21 through day 27. Prolonging of the survival period was observed by the 5'-DFUR administration and the increase in the liver weight, which reflects tumor growth in the liver, was suppressed. Mice with the LMFS tumor were given 5'-DFUR (0, 0.75, 3.0 mM/kg) every day without Saturday and Sunday from day 21. Mean survival time of the control group was 57.8 +/- 4.9 days. And that of 5'-DFUR groups (0.75, 3.0 mM/kg) was 72.1 +/- 16.0 day (p < 0.05), and 80.5 +/- 9.5 days (p < 0.001), respectively. These results reveal that 5'-DFUR is effective for not only the primary site but also the liver metastasis.
