Effect of total parenteral nutrition on survival in advanced colon cancer.
To determine if total parenteral nutrition (TPN) with constant infusion of hypertonic glucose and amino acids by central vein (35 kcal/kg/day) would influence survival in advanced colorectal carcinoma, 50 patients were randomized to receive either chemotherapy alone or the same drugs plus TPN for 14 days before treatment and a variable period thereafter. Overall median survival was significantly decreased in the TPN patients (79 vs 305 days, P = 0.03). Survival was significantly decreased in the TPN patients who had lost the least percentage of premorbid weight (0-6%) (66 vs 398 days, P = 0.02), and in all TPN males (61 vs 209 days, P = 0.03), when compared to similar controls. TPN did not increase survival in any patient subcategory. Catheter-related and metabolic complications were uncommon. We conclude that TPN as used in this study did not prolong median survival in the group as a whole, and may have shortened survival in males and in patients with little or no prior weight loss.
