Single-fraction IMRT Versus External Beam Radiotherapy for Patients With Spine Bone Metastases (SMART)
Study Overview
Detailed Description
The patients will be given information on the study by the medical personnel of the Radiotherapy Department in connection with the planning of the RT schedule (approximately 1-2 weeks prior to the start of RT). If they are interested in participating in the study, the potential study candidates will be given the Patient Information sheet including the Declaration of Informed Consent, with the request that they reread the information carefully and if they consent to the conditions return the signed declaration when they attend the next appointment. The patients will be given the opportunity to ask the study staff further questions. Among the preconditions for participation in the study is the condition that no metastatic spinal cord compression (tumor distance > 3 mm to myelon) of the metastasized vertebral body is detected in MRI recorded in the course of planning procedure. A block randomization procedure shall be used to ensure the even distribution of the patients into the two intervention groups, stratified to baseline pain level. The patients shall then be assigned 1:1 to one of the two treatment groups on the basis of the baseline measurements. The randomization procedure shall be carried out by a central office. The study personnel responsible for the recruitment and baseline measurements shall have no access to the randomization list, and the study director no influence on the recruitment of the patients. The recruitment phase shall be concluded with the attainment of the planned number of patients (60 patients in total). It shall last twelve months, and is scheduled to start in December 2014. Regular study participation shall end six months after enrolment into the study or, where applicable, with the respective patient's death. The aim of the trial was to evaluate the pain relief after RT of patients with spinal bone metastases. Thereby two different techniques were evaluated: single fraction IMRT with 1 x 24 Gy versus fractionated RT with 10 x 3 Gy. The primary endpoint was defined as pain relief > 2 points according to visual analog scale (VAS) measured at the irradiated region up to three months after the end of RT (t2). Secondary endpoints were quality of life (QoL), fatigue, pain, overall survival, bone survival, local control, pathological fracture, and neurological deficit. The baseline examination shall be carried out on the first day of radiotherapy prior to the start of therapy and is scheduled to comprise the comprehensive recording of the sociodemographic data, the recording of the current pain situation, the fear of suffering fractures, the quality of life, and the current degree of fatigue. The follow-up examinations shall take place after the end of radiotherapy (day of the last fraction) and twelve weeks and six months after radiotherapy, measuring those parameters recorded at the baseline examination. The further follow-up examinations shall correspond to those carried out as standard after-care investigations.
The secondary endpoints such as fatigue, quality of life, and anxiety shall be recorded using validated questionnaires (EORTC QLQ FA13 (11), EORTC QLQ BM22 (12) and the questionnaire to record stress in cancer patients (FBK) according to Book et al. (13). All patients will also be asked to record their pain history using a pain diary (documentation of medication daily during treatment, once weekly after the end of treatment, VAS pain scale). Furthermore, the local control was assessed by means of CT images taken prior to, three and six months after RT. The pain response was documented on the VAS (range 0-10). Complete response (CR) was defined as VAS = 0 after three and six months, partial response (PR) as an improvement by at least two score points after three and six months, according to the international consensus response categories by Chow et al. (14). Overall survival (OS) was defined as time from initial diagnosis until death, bone survival as time from initial diagnosis of spinal bone metastasis until death.
Radiotherapy Immobilization was assessed with Aquaplast head mask®, vacuum mattress and Wingstep®. On the basis of the planning-CT risk organs and clinical target volume (CTV) were contoured. CTV confirmed planning target volume (PTV). The dose of PTV occured at the 80%-isodose, encircling the PTV. The RT procedure in group A was conducted as IMRT (Tomotherapy or Step-and-shoot IMRT) 24 Gy in a single-fraction occured at the 80%-isodose. In group B, RT was performed as irradiation of the involved vertebral body as well as the ones immediately above and below to a total-dose of 30 Gy with a single daily dose of 3 Gy using 6 MV individually-formed beams (Linac, multileaf collimator) after CT-scan based 3D planning. The tolerance doses of organs at risk were used according RTOG 0631 study.
