Clinical Trial Summary

Cancer pain deteriorated in quality of life and related with numerous psychosocial problems. Over the one third of cancer patient suffered from moderate to severe cancer pain, even under adequate pain management. The 18F-fluoro-2-deoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) images can provide quantitative results in clinical oncology. As a functional neuroimaging, the PET evidently provided anatomical activated regions, size, and spatial extent information. In this study, we use FDG-PET to investigate changes concerning the glucose metabolism in the brain with or without cancer pain. Therefore, we may provide useful information to treatment target in cancer pain patients.

Description:

Overall, cancer incidence has decreased and the rate of cancer deaths in both men and women has also significantly declined among both men and women in all site.However, the prevalence of chronic pain is 28.2%, ranging from 22.5% to 35.4%, depending on the location of the primary tumor, and neuropathic characteristics were observed in 19.9% of patients with chronic cancer pain. Despite numerous studies on cancer pathogenesis and diagnosis, few reports have demonstrated the brain mechanism underlying cancer pain. One study used resting functional magnetic resonance imaging (fMRI) to identify the changes in the functional brain network of chronic bone cancer pain mice under anesthesia. Cancer-induced bone pain (CIBP) might alter resting state activity of the cingulate cortex, prefrontal cortex (PFC) and ventral striatum, indicating a strong affective component of the CIBP mice.In imaging studies of human patients with cancer, patients with chronic cancer pain exhibited activation in the PFC. The 18F-fluoro-2-deoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) images can provide quantitative results in clinical oncology.Owing to the higher glucose metabolic rate in the brain, brain FDG-PET images are not routinely used in the clinical setting. However, several studies have demonstrated functional brain changes in human pain condition.In this study, we use FDG-PET to investigate changes concerning the glucose metabolism in the brain with or without cancer pain.
