Patients will receive Pulsed Radiofrequency (PRF) on Dorsal root ganglion(DRG) of the selected metastatic painful dorsal vertebrae, with temperature 42°C for 480 sec.,2 active cycles per second of 20 milliseconds each , with a voltage output 40 to 60-V range, impedance ranges between 150 and 400 Ohms at all levels using Fluroscopic guidance (FG).

Patients will receive Thermal Radiofrequency (TRF) on Dorsal root ganglion(DRG) of the selected metastatic painful dorsal vertebrae, with temperature 80°C for 90 sec.,2 cycles, using Fluoroscopic guidance (FG) .

The control group will have identical needle placement and preparation like the 2 previous groups without the RF lesion, but with the injection of particulate Betamethasone steroids and local anesthetic on DRG of the selected metastatic painful dorsal vertebrae, using Fluoroscopic guidance (FG).

RF will be performed with the patient in a prone position with mild flexion of the spine. Fluoroscopy beam positioned in an antero-posterior direction. A 10 cm RF needle 20 G with a 10 mm active tip.The needle is inserted in a slightly medial-cephalad direction under the transverse processes, and using lateral fluoroscopic imaging, incrementally walking into the thoracic intervertebral foramen. So the location of the needle tip confirmed by sensory stimulation at 50 Hz. The point of maximum stimulation is at 0.5 V intensity and this is designated to be the location of the DRG. Slight redirection can be done to optimize the stimulation; injection of contrast reveals epidural uptake. After establishing the site for the RF, 1 ml 2% lidocaine should be injected through the needle.

PRF on DRG

Similar to the group of " PRF on DRG", but the types of the waves will be different as previously described

TRF on DRG

Similar to the previous groups, but without applying any type of Radio-frequency but just injecting steroids and local anesthetics as previously described

AIM OF THE WORK To evaluate the effectiveness and safety of Pulsed and Thermal Radiofrequency lesion of the dorsal root ganglion (RF-DRG) on a consecutive group of patients presenting with chronic thoracic pain due to vertebral bone metastasis.

STUDY DESIGN This is a Prospective Randomized Controlled trial that will be conducted at the National Cancer Institute. All patients who are eligible for the study will be included and randomized into 3 equal groups.

PATIENTS AND METHODS After approval from the Ethics Committee at the National Cancer Institute, Cairo University, and obtaining written informed consent, eighty-one patients with thoracic segmental pain due to metastasis, unresponsive to conventional therapy and meeting the inclusion criteria will be randomly assigned to either one of the two types of treatment, PRF or TRF lesioning of the DRG or the control group. Patients will be carefully evaluated for neurologic deficits and side effects. Assessment of pain will be done at baseline then at 1, 3, 6 months after the procedure. Randomization will be done using randomized permuted block design. Randomization list will be generated through random.org online site.

Patients will be randomly assigned and divided into 3 equal comparable groups. Before the procedure, laboratory investigations, Dorsal X-ray, CT and MRI will be done. All Patients will be interviewed and examined by physicians trained in interventional pain management. Patients will be carefully assessed on physical exam for sensory, motor, or reflex deficit and carefully documented. Patients will be informed about the technique of the blocks, and written informed consents will be obtained.

The types of measures used to assess pain relief will include single rating scales; VAS, and multiple-dimension composite measures; Oswestry Low Back Pain Disability Questionnaire (ODI), The European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and QLQ-BM22.

Dorsal Root Ganglion Thermal Radiofrequency Versus Pulsed Radiofrequency for Metastatic Pain in Thoracic Vertebral Body

Comparison Between Dorsal Root Ganglion Thermal Radiofrequency Versus Pulsed Radiofrequency for the Management of Intractable Metastatic Pain in Thoracic Vertebral Body

All the data that will be found relevant to the primary and secondary outcome

The QLQ-C30 is composed of both multi-item scales and single-item measures. These include five functional scales, three symptom scales, a global health status / QoL scale, and six single items. Each of the multi-item scales includes a different set of items - no item occurs in more than one scale. All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level.

Thus a high score for a functional scale represents a high / healthy level of functioning, a high score for the global health status / QoL represents a high QoL, but a high score for a symptom scale / item represents a high level of symptomatology / problems e.g. a higher score in " Financial difficulties" represents a greater difficulty

The scoring procedure for the QLQ-BM22 module is identical in principle to that for the function and symptom scales/items of the QLQ-C30. Each sub scale is then linearly converted to a score from 0 to 100. For the QLQ-BM22, a higher score indicates worse symptom burden for painful sites and pain characteristics, and better functioning for functional interference and psychosocial aspects. With regards to the positive phrasing of questions 21 and 22, the scoring must be reversed prior to statistical analysis. The item range for each scale/item is 3.

The VAS is a horizontal line,from 0 to 100 mm in length, anchored by word descriptors at each end such as "no pain" on the left and "severe pain" on the right. The patient marks on the line three pain ratings, corresponding to current, best and worst intensity of pain experienced over the past 24 hours.High VAS means worsening of pain. The average of the 3 ratings will be used to represent the patient's level of pain over the previous 24 hours. The VAS score is determined by measuring in millimetres from the left hand end of the line to the point that the patient marks.The VAS has consistently demonstrated sensitivity to changes in cancer pain associated with treatment or time ) and usually shows strong associations with other pain intensity ratings, it appears adequately valid and reliable as measures of pain intensity among the many different samples of persons with cancer

ODI is a self-administered questionnaire divided into ten sections, each with six items designed to assess limitations of various activities of daily living. Each section is scored on a 0 to 5 scale, with 5 representing the greatest disability.If a patient marked more than one statement for a question, the highest scoring statement is recorded as the true indication of disability. The scores are assessed from 0% to 20% to indicate minimal disability, 20% to 40%, to indicate moderate disability, 40% to 60% to indicate severe disability, 60% to 80% to indicate crippled, and 80% to 100% to indicate bed bound or exaggerating their symptoms

from either the technique as pneumothorax, Neurological defects, Dysthesia and hypoesthesia, anesthesia dolorosa and burning pain or local anesthetic complications.
