Safety and Efficacy of Dose-Escalated Radiation Therapy With a Simultaneous Integrated Boost for the Treatment of Spinal Metastases. Pract Radiat Oncol 2023; 13:e7-e13. [PMID: 36604100 DOI: 10.1016/j.prro.2022.08.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2022] [Revised: 08/25/2022] [Accepted: 08/28/2022] [Indexed: 12/29/2022]
Abstract
PURPOSE Intensity modulated radiation therapy (RT) for spine metastases using a simultaneous integrated boost (SSIB) was shown as an alternative to the treatment of select osseous metastases that are not amenable to spine stereotactic radiosurgery. We sought to update our clinical experience using SSIB in patients for whom dose escalation was warranted but spine stereotactic radiosurgery was not feasible. METHODS AND MATERIALS A total of 58 patients with 63 spinal metastatic sites treated with SSIB between 2012 and 2021 were retrospectively reviewed. The gross tumor volume and clinical target volume were prescribed 40 and 30 Gy in 10 fractions, respectively. RESULTS The median follow-up time was 31 months. Of 79% of patients who reported pain before RT with SSIB, 82% reported an improvement following treatment. Patient-reported pain scores on a 10-point scale revealed a significant decrease in pain at 1, 3, 6, and 12 months after SSIB (P < .0001). Additionally, there were limited toxicities; only 1 patient suffered grade 3 toxicity (pain) following RT. There were no reports of radiation-induced myelopathy at last follow-up, and 8 patients (13%) experienced a vertebral column fracture post-treatment. Local control was 88% (95% confidence interval [CI], 80%-98%) and 74% (95% CI, 59%-91%) at 1 and 2 years, respectively. Overall survival was 64% (95% CI, 53%-78%) and 45% (95% CI, 34%-61%) at 1 and 2 years, respectively. The median overall survival was 18 months (95% CI, 13-27 months). Multivariable analysis using patient, tumor, and dosimetric characteristics revealed that a higher Karnofsky performance status before RT (hazard ratio, 0.44, 0.22-0.89; P = .02) was associated with longer survival. CONCLUSIONS These data demonstrate excellent pain relief and local control with limited acute toxicities following treatment with RT using SSIB to 40 Gy. Collectively, our data suggest that dose escalation to spine metastases using SSIB can be safe and efficacious for patients, especially those with radioresistant disease. Further investigation is warranted to validate these findings.

Comparing Outcomes of Oligometastases Treated with Hypofractionated Image-Guided Radiotherapy (HIGRT) with a Simultaneous Integrated Boost (SIB) Technique versus Metastasis Alone: A Multi-Institutional Analysis. Cancers (Basel) 2022; 14:cancers14102403. [PMID: 35626008 PMCID: PMC9139819 DOI: 10.3390/cancers14102403] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 05/04/2022] [Accepted: 05/11/2022] [Indexed: 11/16/2022] Open
Abstract
Simple Summary Hypofractionated image-guided radiotherapy (HIGRT) is a common method in which high doses of radiation are delivered to treat oligometastatic disease. We have previously reported on the clinical outcomes of treating oligometastases with radiation using an elective simultaneous integrated boost technique (SIB), delivering higher doses to known metastases and reduced doses to adjacent bone or nodal basins. Here we compare outcomes of oligometastases receiving radiation targeting metastases alone (MA) versus those treated via an SIB. Both SIB and MA irradiation of oligometastases achieved high rates of tumor metastases control and similar pain control. Further investigation of this technique with prospective trials is warranted. Abstract Purpose: We previously reported on the clinical outcomes of treating oligometastases with radiation using an elective simultaneous integrated boost technique (SIB), delivering higher doses to known metastases and reduced doses to adjacent bone or nodal basins. Here we compare outcomes of oligometastases receiving radiation targeting metastases alone (MA) versus those treated via an SIB. Methods: Oligometastatic patients with ≤5 active metastases treated with either SIB or MA radiation at two institutions from 2013 to 2019 were analyzed retrospectively for treatment-related toxicity, pain control, and recurrence patterns. Tumor metastasis control (TMC) was defined as an absence of progression in the high dose planning target volume (PTV). Marginal recurrence (MR) was defined as recurrence outside the elective PTV but within the adjacent bone or nodal basin. Distant recurrence (DR) was defined as any recurrence that is not within the PTV or surrounding bone or nodal basin. The outcome rates were estimated using the Kaplan–Meier method and compared between the two techniques using the log-rank test. Results: 101 patients were treated via an SIB to 90 sites (58% nodal and 42% osseous) and via MA radiation to 46 sites (22% nodal and 78% osseous). The median follow-up among surviving patients was 24.6 months (range 1.4–71.0). Of the patients treated to MA, the doses ranged from 18 Gy in one fraction (22%) to 50 Gy in 10 fractions (50%). Most patients treated with an SIB received 50 Gy to the treated metastases and 30 Gy to the elective PTV in 10 fractions (88%). No acute grade ≥3 toxicities occurred in either cohort. Late grade ≥3 toxicity occurred in 3 SIB patients (vocal cord paralysis and two vertebral body compression), all related to the high dose PTV and not the elective volume. There was similar crude pain relief between cohorts. The MR-free survival rate at 2 years was 87% (95% CI: 70%, 95%) in the MA group and 98% (95% CI: 87%, 99%) in the SIB group (p = 0.07). The crude TMC was 89% (41/46) in the MA group and 94% (85/90) in the SIB group. There were no significant differences in DR-free survival (65% (95% CI: 55–74%; p = 0.24)), disease-free survival (60% (95% CI: 40–75%; p = 0.40)), or overall survival (88% (95% CI: 73–95%; p = 0.26)), between the MA and SIB cohorts. Conclusion: Both SIB and MA irradiation of oligometastases achieved high rates of TMC and similar pain control, with a trend towards improved MR-free survival for oligometastases treated with an SIB. Further investigation of this technique with prospective trials is warranted.

Abstract
Conventional radiotherapy is a pivotal treatment in the management of bone metastasis. It is indicated primarily for palliative, analgesic, or decompressive purposes and in the prevention of severe bone events such as fractures and spinal cord compressions. It should be performed as early as possible from the onset of symptoms or within 14days following a surgical procedure of decompression or bone stabilization. Except in some cases, a pattern of 8Gy single dose is currently recommended, possibly renewable, by being vigilant on associated treatments which some, like antiangiogenics, must be imperatively suspended.
