Purpose: Ketamine is effective on neuropathic pain that is difficult to respond to opioids among cancer pains, due to its N-methyl-D-aspartate (NMDA) receptor antagonism action. The purpose of this study was to evaluate the effect of oral ketamine on neuropathic pain. Methods: We retrospectively investigated the dosage and the administration period of oral ketamine in 31 patients for one year from December 2004. Results: Pain-relief was achieved in 22 of 31 patients, the average of initial dose was 107.3mg/day and the average administration period was 63 days. Seven patients discontinued oral ketamine within 7 days because of nausea/ vomiting (4 patients) or drowsiness (3 patients). Two patients had no sufficient pain-relief. Conclusion: This experience suggests that oral ketamine is effective on the management of neuropathic pain. Palliat Care Res 2008; 3(1): 216-220

Alleviating fatigue of a patient with advanced cancer often meets troubles, for which medication is restricted. We experienced two cases with cancer-related fatigue, in which 4,000mg of taurine a day was administered orally and the improvement of the Cancer Fatigue Scale (CFS) score was identified as a result. There hasn't been any literature reporting the effect of taurine to cancer-related fatigue yet. However, taurine has been known as a medicine with various effects for quite a long time, and it is possible that it will be recognized as one of the medicines effective for cancer-related fatigue.

Purpose: In terminally ill patients with advanced cancer,it is recognized that delirium is reversible in 20-50% of the patients with it. Identification of its cause is vital to ensure the quality of life of the patients with delirium at the end of life. We would like to report a case of the advanced cervical cancer patient with delirium, successfully treated by intravenous administration of vitamin B1. Case: An 83-year-old woman, who was diagnosed the advanced cervical cancer with carcinomatous peritonitis, was admitted to Shizuoka Cancer Center Palliative Care Unit. Four days after the admission, she presented sleep-wake cycle disturbance, poor attention, poor concentration,and short-term memory loss, and these conditions were diagnosed with delirium. Vitamin B1 deficiency was suspected by normal examinations including laboratory results and head computed tomography except for the low level (19ng/ml) of vitamin B1. One week after starting intravenous administration of vitamin B1, the symptoms of delirium were improved. Conclusion: In this case, delirium by vitamin B1 deficiency developed even though having adequate oral intake (about 1,000kcal/day), indicating malabsorption of vitamin B1 due to hypoperistalsis and edema of the bowel. Advanced cancer patients can easily develop vitamin B1 deficiency due to inadequate oral intake, increased consumption of vitamin B1 and malabsorption of vitamin B1. Therefore,the examination of vitamin B1 deficiency is necessary for patients with delirium that cannot be specified. Palliat Care Res 2009; 4(2): 330-333
