Evaluation of Safety and Efficacy of Radiofrequency Lesioning of Thoracic Dorsal Root Ganglion in Chest Cancer Pain Patients Daily Activities and their Quality of Life

Background: in controlling cancer pain it is commonly inadequately managed for these patients leading to suffer in the form of physical disabilities, psychological disturbance, avoiding treatment. Therefore pain that is caused by cancer may directly affect the patient's quality of life; by having an effect on his/her daily activity, physical state and also psychological and emotional status. Thus, making pain relief and control the patient's right; right for a new life "pain free" or at least tolerable non-disabling pain. Aim of the work: this study aimed to test both the efficacy and safety of thermo-coagulative ablation of the thoracic dorsal root ganglia for pain control in cancer patients that have refractory chest pain And the impact on quality of life for patients. Patients and Methods: our prospective study was done on sixty-five patients selected from pain clinics of both the National Institute of Cancer, Cairo University and Aswan University with refractory chronic chest cancer pain according to the inclusion and exclusion criteria. The complete duration of the follow up lasted 3 months postinterventional; with assessments after 1 week, 1 month and 3 months. At each follow up each patient was reassessed with the following assessments; VAS, ECOG performance status, QOLS, drug consumption, side-effects (complications) and patient satisfaction. Results: we found that with effective pain relief there was a significant reduction in the mean VAS values which means that there was functional improvement, in all the postinterventional follow ups. Also, there was an improvement in the functional state of the patients throughout the follow-up post-intervention with regardsto the ECOG performance statusfrom the results. In addition to the ECOG improvement there was also a significant improvement in the QOL (Quality of Life) results, which was due to the pain relief. Regarding drug consumption, it was recorded that all three drugs; pregabalin, oxycodone and amitryptline, should maximum reduction after 1 month following the intervention, with a slight increase 3 months post-interventional, which matched the degree of pain reduction based on the pain scaling scores. Only 11% of our patients were found with numbness and neuritis, which were the only two complications reported. With regards to our patients, 30.6% certainly would repeat the procedure, 54.8% probably would, and 12.9 % probably would not while, only 1.6% certainly would not repeat it. With25.8% certainly would recommend the same procedure, 56.5% probably would, 14.5% probably would not and only 3.2% certainly would not recommend it. Conclusion: we concluded that thermal radiofrequency ablation is considered an alternative for treating refractory chronic chest cancer pain of several types and causes. This is because of its efficacy, safety and ease of use, patient’s quality of life of was largely affected.
