Preoperative chemotherapy and total parenteral nutrition in colon cancer
2006
AIM: The objective of this study was to determine the effect of TPN after surgery in patients with colon carcinoma and preoperative chemotherapy. MATERIAL AND METHOD: The study included 27 patients, 16 men and 11 women, with a mean age of 62.1 +/- 11.2 years. The patients were divided into two groups according to whether they had undergone chemotherapy (Group A; n = 11) or not (Group B, control; n = 16) prior to surgery. Almost two thirds of the patients were in stage III of the disease. Among those receiving this treatment, 60% were given 5-fluorouracil plus leucovorin at a dose of 5.5 +/- 2.7 cycles/patient and the others received different regimens. TPN was established early with a mean of 11.7 +/- 9.2 days. The clinical and nutritional assessment was performed before surgery and at the end of TPN administration. RESULTS: The mean body mass index (BMI) was 24.1 +/- 2.2 kg/m2. Comparison between the groups before the start of TPN showed statistically significant differences in red blood cell and platelet counts (P = .013 and P = .02, respectively). These differences had disappeared at completion of TPN, suggesting that this treatment can reverse the hematological changes induced by chemotherapy. CONCLUSION: In patients who receive chemotherapy before surgery and in whom TPN it was indicated the combination of these two treatments could be beneficial.
