Over the years there has been a great deal of controversy on the effect of vitamin C on cancer. To investigate the effects of vitamin C on cancer patients' health-related quality of life, we prospectively studied 39 terminal cancer patients. All patients were given an intravenous administration of 10 g vitamin C twice with a 3-day interval and an oral intake of 4 g vitamin C daily for a week. And then we investigated demographic data and assessed changes in patients' quality of life after administration of vitamin C. Quality of life was assessed with EORTC QLQ-C30. In the global health/quality of life scale, health score improved from 36+/-18 to 55+/-16 after administration of vitamin C (p=0.001). In functional scale, the patients reported significantly higher scores for physical, role, emotional, and cognitive function after administration of vitamin C (p<0.05). In symptom scale, the patients reported significantly lower scores for fatigue, nausea/vomiting, pain, and appetite loss after administration of vitamin C (p<0.005). The other function and symptom scales were not significantly changed after administration of vitamin C. In terminal cancer patients, the quality of life is as important as cure. Although there is still controversy regarding anticancer effects of vitamin C, the use of vitamin C is considered a safe and effective therapy to improve the quality of life of terminal cancer patients.

BACKGROUND: Although fatigue is the most common symptom in primary care, both doctors and patients tend to overlook it. According to one study, 27% of the adults felt fatigued for one week and 6% of the adults complained of unexplained fatigue for over two weeks. Stress play an important role in the etiology of fatigue. Thus, antioxidants are currently taken by people who complain of fatigue. Vitamin C is one of the most common antioxidants. We intend to find out whether intrarenous vitamin C is really helpful or not in people who complain of fatigue. METHODS: We have investigated 19 outpatients who chiefly complained of fatigue and visited the department of family medicine at one university hospital from July 1, 2004 to Nov 30, 2005. The patients were treated by Vitamin C 10g and Vitamin B complex injection for 4 weeks, and they conducted a questionnaire survey concerning the severity of symptom before and after injection. The questionnaire with 9 questions consisted of 7 score index. The results were statistically analyzed with Wilcoxon Signed Ranks test and a P-value under 0.05 was considered significant. RESULTS: Three patients were males and 16 patients were females. The average age group was 47.7+/-13.6 years. While the fatigue severity score of the patients before vitamin C injection was 5.2 (3.0~7.0), the fatigue severity score after injection was 3.3 (1.4~4.8), which was significantly decreased (P<0.0001). CONCLUSION: We think that the vitamin C intravenous injectioned to people who complained of fatigue was helpful.

PURPOSE: Total thyroidectomy with central lymph node dissection (CLND) is a treatment modality of choice for thyroid cancer. Hypocalcemia is the most common complication after total thyroidectomy. The aim of the current study was to determine the association between surgery-related clinical factors and postoperative hypocalcemia. METHODS: A prospective analysis was performed for 101 patients who underwent total thyroidectomy with CLND for papillary cancer from June 2013 to June 2014. Correlation between clinicopathologic factors and postoperative hypocalcemia was analyzed. RESULTS: Based on the postoperative day-2 calcium, 56 patients (55%) developed hypocalcemia and 45 patients (45%) were normal. No significant differences in histopathologic (tumor size, tumor focality, histologic type, number of retrieved lymph nodes, metastatic lymph node, thyroiditis, retrieved parathyroid gland) findings were observed between the hypocalcemia group and normal calcium group. Mean value of the postoperative day-0 parathyroid hormone (PTH) was significantly lower in the hypocalcemia group (hypoca1cemia group: 14.3+/-9.4 pg/mL; normal group: 25.0+/-16.4 pg/mL; P<0.001). In logistic regression analysis, postoperative PTH was a factor significantly affecting postoperative hypocalcemia (OR 0.93; CI: 0.90-0.97; P<0.001). In ROC analysis, the cut-off value of PTH was 19.965 (sensitivity 79%, specificity 58%), and area under the curve (AUC) was 0.709 (95% CI: 0.607-0.811). CONCLUSION: Postoperative PTH was a factor predicting hypocalcemia after total thyroidectomy with CLND. Use of postoperative PTH as a screening tool for prediction of postoperative hypocalcemia would be useful in management of patients with hypocalcemia.
