[Frequency, time and type of metastasis of different transplantable tumors in mice]

The character of metastasis of 9 strains of transplantable mouse tumours in conventional subcutaneous inoculation was studied. There were differences in the frequency, intensity, and types of metastasis of different tumours. Periods of onset of metastases of Lewis lung carcinoma and RL-67, and also of sarcoma-37 were established. Sarcoma, Lewis and RL-67 lung carcinomas, adenocarcinoma of the colon AKATOL, Cloudman's melanoma and B-16 metastasized most intensively. Sarcoma-37 metastasizing into the regional and remote lymph nodes, Lewis lung carcinoma and melanomas metastasizing into the lungs, RL-67 lung carcinoma metastasizing into the lungs, kidneys, adrenal glands, ovaries, the heart, and also adenocarcinoma of the colon AKATOL metastasizing into the lymph nodes and the liver can be used as models for the research in the field of drug action upon metastases and the metastasis process.
