Objective  To investigate the effect of short-term administration of growth hormone (GH) on serum insulin-like growth factor-1 (IGF-1) level and nutritional status in patients after gastrointestinal operation, and evaluate whether postoperative application of GH rise the risk of tumor recurrence. Methods  Forty-eight patients undergoing major gastrointestinal operation were randomly divided into two groups: GH group (n=24) and control group (n=24). The two groups received isocaloric isonitrogenous nutrition with daily injection of either GH 0.15 U/kg or placebo for a period of day 3-9 postoperatively. Serum albumin, fibronectin, and IGF-1 were measured before operation as a baseline, and day 3 and 10 after operation using standard laboratory techniques. Nitrogen balance was measured daily from day 3 to day 9 after operation. Postoperative complications and adverse reaction were observed. All cancer patients received regular abdominal B-type ultrasonography and chest X-ray examination during 2 years of follow-up. Results  Compared with control group, GH treatment did not influence serum IGF-1 and serum albumin level (P gt;0.05), but improved significantly the rise from day 3 to day 10 of serum fibronectin level 〔(22.8±5.8) mg/L vs.(9.6±3.6) mg/L, P<0.05〕 and the cumulative nitrogen balance 〔(11.37±16.82) g vs.(-9.11±17.52) g, P<0.01〕 postoperatively. There was no severe adverse effects and complications during GH treatment. The tumor-recurrence rates were not statistically different between two groups during follow-up. Conclusions  Short-term administration of low-dose GH combined with early nutrition support can improve total nitrogen retention and protein metabolism, but not influence serum IGF-1 level after major abdominal surgery. Short-term administration of low-dose GH may not cause the tumor-recurrence.
