Contents of the progesterone receptors (PgR) and estrogen receptors (ER) in 18 gastric adenocarcinoma tissues were determined using both the dextran-coated charcoal (DCC) assay and enzyme immunoassay (EIA). PgR were found in 15 cancer tissues (range, 1.0-58.8 fmol/mg protein) and 12 normal mucosal tissues (range, 1.4-26.8 fmol/mg protein) by DCC assay, whereas only 6 cancer tissues (ranged, 0.2-3.3 fmol/mg protein) and 7 normal mucosal tissues (range, 0.1-0.8 fmol/mg protein) had measurable PgR by EIA analysis. Similar results were observed for ER. DCC assay found ER in 12 cancer tissues (range, 2.9-112.6 fmol/mg protein) and 12 normal mucosal tissues (range, 1.2-36.6 fmol/mg protein), whereas EIA measured ER in 16 cancer tissues (range, 0.1-3.5 fmol/mg protein) and 15 normal mucosal tissues (range, 0.1-4.8 fmol/mg protein). No significant correlation between DCC and EIA was observed for either PgR or ER. DCC assay and its modified procedures including 5% DCC stripping of cytosol and/or the addition of sodium molybdate in buffer were simultaneously measured in 5 gastric adenocarcinoma tissues and 1 gastritis cystica polyposa tissue (a precancerous lesion). Higher receptor levels were found by the modified procedures than by conventional method. Using the DCC procedure with addition of sodium molybdate in buffer for receptor analysis, PgR and ER were found in gastric tissues in six patients, with significantly increased levels of measurable PgR. The results suggest that PgR and ER may be involved in the physiology of normal and gastric cancer tissues; their clinical implications are worthy of further study.
