title: Lewis lung carcinoma lines with different metastatic behavior: response to ICRF-159.
abstract: Three Lewis lung carcinoma lines (3LL) with different metastatic behavior have been investigated with regard to their response to Razoxane (ICRF-159). The effects of different schedules were tested both on primary and secondary tumors. Results show that the lines are heterogeneous in their response to this antimetastatic agent and that, in particular, BM21548 the least metastatic line is also less sensitive to ICRF-159. A better response can be achieved with this line by a proper fractionation regimen which takes into account the delayed metastasis release from primary tumor. As far as M1087, the most metastatic line is concerned, secondaries are greatly affected by ICRF-159 treatment if performed at a moderately advanced stage of growth. On the contrary, metastases from early tumor stages can be better controlled by radical surgery of the primary implant than by treatment with ICRF-159.
