Methods from April 2016 to June 2017, 21 patients with advanced malignant tumor were treated with high dose vitamin C in aviation general hospital, chinese medical sciences university. The symptoms of nausea, loss of appetite, abdominal distention, diarrhea, abdominal pain, dizziness, blood glucose, electrolytes (blood Na+, K+, Cl-) and liver and kidney function (alanine aminotransferase, aspartate aminotransferase, total bilirubin, urea, creatinine and Uric acid) were recorded in 21 patients with tumor before and after high dose vitamin C treatment. The paired test was then used to compare these patients' clinical symptoms and blood biochemical parameters after high-dose vitamin C treatment. Results there were no significant changes in blood glucose, electrolytes, liver and kidney function in patients with malignant tumor treated with high dose vitamin C intravenous drip. One patient complained of loss of appetite, one patient complained of nausea and abdominal distention, and one patient suffered from lower limb edema.
