Gc globulin and prealbumin serum levels were determined in a coded serum panel from the National Cancer Institute-Mayo Clinic. Serum samples came from 100 patients with cancer (lung, prostate gland, or gastrointestinal tract), from 50 patients with benign inflammatory diseases from the same organs as those of the cancer patients, and from 50 clinically healthy smokers. No differences were observed among groups in the Gc globulin (vitamin D carrier) serum concentrations; however, prealbumin (vitamin A carrier) serum levels were decreased for patients with benign inflammatory diseases and for cancer patients; the cancer group showed the greatest decrease.
在美国国立癌症研究所-梅奥诊所的一组编码血清样本中测定了Gc球蛋白和前白蛋白的血清水平。血清样本来自100名癌症患者（肺癌、前列腺癌或胃肠道癌）、50名患有与癌症患者相同器官良性炎症性疾病的患者以及50名临床健康的吸烟者。各组之间的Gc球蛋白（维生素D载体）血清浓度未观察到差异；然而，患有良性炎症性疾病的患者和癌症患者的前白蛋白（维生素A载体）血清水平降低；癌症组下降幅度最大。
