The rise of cancer frequency as a function of age is a well-established fact. The aspect of the host age-tumor progression relationship, namely the slower metastatic spread in aged patients, has been investigated to a lesser extent. In the present study, we examined whether host-age-dependent growth rate varies with metastatic capacity of the tumor. The parental B16 and the B16/Col/R, a highly metastatic variant, were employed. A more pronounced growth of both tumors in young as compared to middle-aged mice was found. However, the differential growth in middle-aged versus young mice was more evident in the highly metastatic variant. According to the tumor size data, a sixfold growth reduction in middle-aged mice was observed with B16/Col/R and an only twofold growth reduction was seen with the B16 melanoma. The data might eventually contribute to the finding of more appropriate treatment modalities for the middle-aged cancer patient. |
