The response of solid mammary adenocarcinoma 16/C to treatment with Adriamycin is highly variable and ranges from growth under treatment to complete regression. Tumour and host factors were evaluated to determine the influence of each on the response. We determined that the concentration of Adriamycin in plasma and tumour was a function of tumour size and treatment history in mice bearing mammary adenocarcinoma 16/C. The plasma concentrations following a single dose of Adriamycin (10 mg/kg) increased in proportion to tumour mass without a concurrent increase in tumour concentration. When mice bearing large tumours (greater than 1.0 g) were treated with a multidose protocol, the plasma concentrations were higher and the tumour concentrations lower following the initial dose than following subsequent doses; in tumour-free mice, prior treatment with Adriamycin did not affect the plasma level achieved after a second dose. The magnitude of the decrease in plasma and increase in tumour concentrations was a function of the initial tumour size and the treatment schedule. The increase in tumour levels represented the sum of residual Adriamycin and drug bound as a result of the dose immediately prior to analysis. At the time of the initial treatment, the Adriamycin was distributed within each tumour in proportion to vascular perfusion. The percent of the tumour mass that was well-perfused appeared to increase with repeated treatments. The results indicate that the plasma concentration of Adriamycin did not necessarily reflect the tumour exposure in the mammary adenocarcinoma 16/C model. In hosts bearing mammary adenocarcinoma 16/C--or, possibly, other tumours that produce similar effects on the host--a low initial dose of Adriamycin might modify the distribution, possibly reduce the toxicity and allow escalation of subsequent doses with increased exposure of the tumour.
