We compared the nutritional condition, immunological function, and frequency of adverse effects during concurrent chemoradiotherapy for oral cancer between patients simultaneously receiving enteral hyperalimentation (Racol) (n=20; EHA group) and patients receiving peripheral vein nutrition (n=20; PVN group). Although there was no significant difference in the change of body weight between the two groups, the decrease of plasma albumin values in the EHA group appeared later than in the PVN group. In the PVN group, the number of lymphocytes and lymphocyte blastogenesis significantly decreased on and after day 14. On the other hand, in the EHA group, the number of lymphocytes decreased only on day 14 and no decrease in lymphocyte blastogenesis was observed. While stomatitis developed in all patients, the severity was lower in the EHA group than the PVN one. These results suggest that the simultaneous administration of Racol during concurrent chemoradiotherapy for oral cancer inhibits the deterioration of nutritional and immunological conditions as well as the severity of stomatitis. This nutrient therapy is therefore considered to be a supportive therapy for oral cancer patients.

Many studies, both national and international, have shown that tea has protective effects on many chronic diseases and their risk factors. In cancer prevention, our studies indicated that tea drinking could inhibit the carcinogenicity of various chemical carcinogens, including oral tumors induced by 7,12-dimethylbenz[a]anthracene (DMBA) in Golden hamsters, esophageal tumors in rats by blocking in vivo synthesis of N-Nitroso-methylbenzylamine (NMBzA), esophageal cancer induced by NMBzA in rats, precancerous liver lesions (r-GT and GST-P) induced by diethylnitrosamine (DENA) in rats, intestinal preneoplastic lesion (ACF) and intestinal tumors induced by 1,2-dimethyl-hydrazine (DMH) in rats, lung carcinoma induced by nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone(NNK) in A/J mice. Our studies have also shown that the protective effects of tea against cancer is a combined effects of various tea ingredients, among which the major ones are polyphenols and tea pigments. Based on animal studies, antioxidant properties, protection against DNA damage and modulation of immune functions were found to be the main mechanisms of anticancer effects of tea. In human trials, tea drinking showed protective effects against oxidative damage and DNA damage caused by cigarette smoking. Mixed tea drinking significantly blocked lesion progress in patients with oral mucosa leukoplakia, therefore, demonstrated its protective effects on oral cancer. Our studies have also shown effects of tea on prevention of cardiovascular diseases (CVD). For example, tea pigments was found to significantly inhibit LDL oxidation induced by Cu2+, Fe2+ in in vitro studies. In vivo studies showed that tea could prevent blood coagulation, facilitate fibrinogen dissolution, inhibit platelet aggregation, lower endothelin levels, enhance GSH-Px activities, protect against oxidated LDL-induced damage in endothelium cells, and prevent atherosclerosis of coronary arteries. The mechanisms of these protective effects of tea are possibly related to its antioxidant properties or its inhibition of lipid oxidation. Green tea and pigments was also found to inhibit cardiac hypertrophy induced by renal hypertension in rat models, whose mechanisms might, at least partly, involve its modulation on nitric oxide, angiotensin II and endothelin-1. Clinical intervention trials have indicated that tea and tea extracts decreased blood lipid, improved blood flow of coronary artery, and played an important role in atherosis inhibition and prevention. Our studies also showed that tea drinking has protective effects on diabetes. White tea drinking could significantly relieve symptoms including polyuria, polydipsia, polyphagia and weight loss in diabetic mice, decrease fasting plasma glucose level and improve glucose tolerance. In human trial, continuous white tea drinking could significantly improve symptoms of diabetic patients, such as relieve polydipsia, decrease plasma glucose levels, both fasting and 2 hours after meal, and increase insulin secretion. The effective rate for glucose lowering is 48% in clinical study.
