[Parenteral hyperalimentation in patients with advanced neoplastic disease (author's transl)]

Two groups of patients suffering from advanced neoplastic disease were fed parenterally for a period ranging from 1 to 16 weeks. The parameters considered were: weight change, serum albumin level, lymphocyte transformation test and serum immunoglobulin level. There were 23 patients in one group and 21 patients in the other. Regimens included for group I: saline solution (1000-1500 ml), glucose (100-150 g) and amino acids (15-30 g) per day; for group 2: 40-50 Cal/kg per day (dextrose about 15 g/kg per day), about 2 g of amino acids/kg/day and about 40-50 ml water/kg/day. In addition, 13 patients underwent both treatments sequentially. All the Group I patients lost weight (1.3 kg/week); while out of 23 patients in Group 2, 15 gained weight, 2 remained unchanged and 6 continued to lose weight, but to a lesser rate than before hyperalimentation (the average weight gain was 1.1 kg/week). Serum albumin levels decreased in 19 out of 25 patients in Group I and increased in 14 out of 26 patients of Group 2. Initial values of the lymphocyte blast transformation test were very low in both groups of patients, and an increase was observed only in patients treated by hyperalimentation. The increase was more evident in patients who were not under antiblastic treatment. Changes in serum immunoglobulin levels were not significant. The authors conclude that malnutrition plays a very important role in neoplastic cachexia and can be improved by parenteral hyperalimentation. Although it is possible that in the near future hyperalimentation and conventional neoplastic therapies will play complementary roles in treatment of advanced neoplastic disease, malnutrition is still the specific indication for intravenous hyperalimentation.
