RESUMO
BACKGROUND: Cancer induced bone pain (CIBP) strongly interferes with patient's quality of life. Currently, the standard of care includes external beam radiotherapy (EBRT), resulting in pain relief in approximately 60% of patients. Magnetic Resonance guided High Intensity Focused Ultrasound (MR-HIFU) is a promising treatment modality for CIBP. METHODS: A single arm, R-IDEAL stage I/IIa study was conducted. Patients presenting at the department of radiation oncology with symptomatic bone metastases in the appendicular skeleton, as well as in the sacrum and sternum were eligible for inclusion. All participants underwent EBRT, followed by MR-HIFU within 4 days. Safety and feasibility were assessed, and pain scores were monitored for 4 weeks after completing the combined treatment. RESULTS: Six patients were enrolled. Median age was 67 years, median lesion diameter was 56,5 mm. In all patients it was logistically possible to plan and perform the MR-HIFU treatment within 4 days after EBRT. All patients tolerated the combined procedure well. Pain response was reported by 5 out of 6 patients at 7 days after completion of the combined treatment, and stabilized on 60% at 4 weeks follow up. No treatment related serious adverse events occurred. CONCLUSION: This is the first study to combine EBRT with MR-HIFU. Our results show that combined EBRT and MR-HIFU in first-line treatment of CIBP is safe and feasible, and is well tolerated by patients. Superiority over standard EBRT, in terms of (time to) pain relief and quality of life need to be evaluated in comparative (randomized) study.
RESUMO
AIMS: To evaluate the adjustable single-incision sling (Ajust®) in the treatment of stress urinary incontinence (SUI), when placed under conscious sedation with local infiltration, using the cough test during surgery. METHODS: In this multicenter observational study, 90 women who had moderate to severe SUI, were asked to have the Ajust® procedure performed under sedation with local infiltration with levobupivacain. This allowed for a perioperative cough test to adjust the sling to the urethra till continence was reached. The primary outcome of the study was subjective cure of stress incontinence at 1 year follow up. Secondary objectives were objective and subjective improvement, complications during and after the procedure, and postoperative pain scores. These results were compared with the results of a historical control group of 96 patients who received their Ajust® under general or regional (spinal) anesthesia. RESULTS: At 6 weeks and 12 months, there were no statistical significant differences in the results for subjective cure (83.6% and 71.6% sedation group, 88.4% and 77.2% general/regional anesthesia group), objective cure (96% and 86.9% sedation group, 88.1% and 91.8% general/regional anesthesia group), de novo urgency (10.5% and 6.7% sedation group, 7.1% and 24.1% general/regional anesthesia group) and the patients global impression of improvement (96% and 89.2% sedation group, 91.4% and 84.4% general/regional anesthesia group). CONCLUSION: The performance of a cough test during the placement of an adjustable single-incision sling for the treatment of SUI does not affect the functional outcome, and is therefore not necessary.
