Abstract：
:It is uncertain whether interferon levels in the interstitial fluid of tumors are equivalent to interferon plasma levels and we have investigated this problem in human pulmonary tumors by infusing human recombinant interferon alpha A and natural interferon Beta for about three hours before surgery. By determining the hematocrit and hemoglobin content it was possible to calculate interferon values (International Units/g wet tissue) present in the interstitial fluid of tumor and lung samples, simultaneously. In 14 patients (epidermoids, n = 9 and adenocarcinomas, n = 5) interferon levels in tumor and "normal" lung expressed as percentages of interferon plasma levels were: 9.5 +/- 3.9 and 29.8 +/- 6.9 for recombinant interferon alpha A and 3.1 +/- 0.4 and 10.1 +/- 2.4 for natural interferon Beta, respectively. Differences for both interferons are statistically significant (p less than 0.05). To our knowledge these are the first data indicating that interferon levels in pulmonary tumor interstitial fluid are markedly lower than those in normal lung although they do not clarify the main factor responsible for the decrease, they explain at least in part the negligible therapeutic activity of interferons in these tumors and emphasize the need for new approaches for improving the therapeutic index of interferons.
