[Postoperative changes in acute phase protein in patients with esophageal cancer].
Thirty-three patients with esophageal cancer were studied to assess the relationship between nutritional state and the acute phase protein responses. Blood samples taken preoperatively and days 1, 4, 7 and 14 after operation were analyzed for C-reactive protein, fibrinogen, alpha 1-antitrypsin, alpha 1-acid glycoprotein and haptoglobin. Significant Spearman's coefficients were found between percent of ideal body weight (IBW) and alpha 1-acid glycoprotein (r = -0.42), between prealbumin and alpha 1-anti-trypsin (r = -0.55), and between retinol-binding protein and alpha 1-antitrypsin (r = -0.51). Postoperatively, the levels of C-reactive protein, fibrinogen, alpha 1-anti-trypsin and alpha 1-acid glycoprotein were significantly lower in the poorly nourished group than in the other groups. The changes of acute phase proteins in the immediate postoperative period were affected by the preoperative nutritional state, and were less marked in the poorly nourished patients. Between two groups of patients in whom lymph node dissection was carried out in 2 or 3 areas, no significant differences were observed in the acute phase protein responses postoperatively. The measurement of acute phase proteins is very important in assessing the body defense capacity of the patient, but it should be noted that the changes may be affected by several factors including malnutrition.
