Determining the Effect of Abiraterone on the Metabolism of Oxycodone in Men With Prostate Cancer (the ENABLE Study)

Prostate cancer often leads to bone metastases, which require adequate pain management with opioids such as oxycodone. This study investigates whether abiraterone - a drug used in the treatment of prostate cancer - affects the pharmacokinetics of oxycodone in order to improve pain management.

Real World Study of Oxycodone/Naloxone Sustained-Release Tablets (Mimeixin) for Patients With Severe Cancer Pain

This study is a prospective, single-arm, multicenter, real-world study to evaluate effect of bowel function, analgesic effect, quality of life, and safety of Mimeixin® in Chinese patients with severe cancer pain.

Evaluate the Efficacy of Radiofrequency Ablation/Vertebroplasty with or Without SBRT for Treating Painful Spinal Vertebral Metastases

This study is a prospective, multicenter, open, practical, randomized controlled, non inferiority effect clinical study initiated by researchers, which aims to evaluate the clinical efficacy and safety of radiofrequency ablation/vertebroplasty and radiofrequency ablation/vertebroplasty combined with SBRT in the treatment of painful spinal metastases. This study plans to include about 120 cases in about 3 research centers nationwide, including the Department of bone oncology of Shanghai First People's Hospital (main center, 60 cases), the Department of bone oncology of the Third Affiliated Hospital of Southern Medical University (sub center 1, 30 cases), and the Department of bone oncology of Peking University People's Hospital (sub center 2, 30 cases). The patient was diagnosed with spinal metastasis of malignant tumor and had pain of more than 3 points. The subjects with spinal metastasis located at t5-l5 were selected for clinical research. All patients were treated with RFA/PVA minimally invasive surgery. In principle, no more than 2 vertebral bodies were treated. All patients will receive MRI/CT examination of the affected spine within 6 weeks before enrollment to determine the degree of spinal involvement. All patients were randomly divided into experimental group and control group after minimally invasive surgery, the ratio was 1:1. The patients in the experimental group recovered to the original system treatment about two weeks after minimally invasive surgery; The control group began to receive SBRT radiotherapy of the surgical vertebral body in about two weeks, and the radiotherapy time was two weeks. According to the recommendations of the Department of radiotherapy, SBRT radiotherapy should use any of the following dose and grading scheme: 4 times 24gy, 5 times 30Gy, 6 times 36Gy, 7 times 42GY. The patients in the two groups were followed up after treatment, and evaluated at 1, 2 and 4 weeks and 3, 6 and 12 months after treatment. The NRPS pain degree and pafi pain function comprehensive score were evaluated, and the local lesions were evaluated at 1, 3, 6 and 12 months after operation. To evaluate the local control of spinal metastases, pain improvement and quality of life changes of the two treatment strategies.

Upfront EUS CGN/CPN vs Conventional Step up Approach for Inoperable Painful Pancreatic Cancer

Patients with unresectable pancreatic cancer are often demoralized by intractable, persistent and incapacitating pain. It must be managed aggressively and strong opioids are recommended as the mainstay of treatment. However, patients develop opioid-related adverse effects. EUS-guided celiac plexus neurolysis (CPN) and celiac ganglion neurolysis (CGN) has been shown to provide high efficacy for pain control. The optimal timing, however, is in debate.
