| Outline of Final Research Achievements |
Cancer patients have a large variation in clinical responses to opioid analgesics at each cancer disease stage. Plasma exposure of and clinical responses to opioid analgesics are potentially influenced by the genetic factors including genetic variants of drug metabolizing enzyme and non-genetic factors including gender and physiological changes accompanied with cancer progression. This study evaluated the relationships between the plasma exposure of and clinical responses to opioid analgesics including transdermal fentanyl and oral tramadol, drug tolerance, and adverse effects at each cancer disease stage. In this study, the cancer disease stages employed the serum inflammation markers including IL-6 and CRP, and cancer symptom- and inflammation-based scores. From the cross-sectional analyses for cancer patients, this study revealed the interindividual factors related to the pharmacokinetics of opioid analgesics, pain relief, and adverse effects based on cancer disease stages.
