Re-Irradiation

01/01/2015 - "Radiation Therapy Oncology Group (RTOG) 1205 will establish the role of re-irradiation for recurrent GBM, however our study suggests that CyberKnife with chemotherapy can be safely delivered, and is most effective in patients with smaller frontal lobe tumors, good performance status, or long interval from diagnosis."
06/01/2022 - "Level III: When the target tumor is amenable for additional radiation, re-irradiation is recommended as it provides improved local tumor control, as measured by best imaging response. "

10/01/2016 - "Improved MBDCA dosimetry could be important for re-irradiation, technique inter-comparison and/or the assessment of secondary cancer induction risk, where accurate dosimetry in the whole patient anatomy is of the essence."
03/01/2011 - "Reirradiation of canine nasal tumors resulted in a second clinical remission in eight of nine dogs, although the second response was less complete. "

07/01/2016 - "The aim of this study was to evaluate the efficacy of re-irradiation in patients with recurrent gliomas and to identify subgroups for whom re-irradiation for recurrent gliomas is most beneficial. "

06/03/2014 - "Re-irradiation has been shown to be a valid option with proven efficacy for recurrent high-grade glioma patients. "
02/01/2009 - "Treatment options for recurrent high-grade glioma after a complete course of radiotherapy comprise surgery, reirradiation and chemotherapy but the efficacy of any of the given salvage treatments is limited. "
11/01/2017 - "The purpose of this study was to evaluate the safety and efficacy of PET and MRI guided re-irradiation of recurrent high-grade glioma (HGG) and to assess the impact of radiotherapy dose, fractionation and irradiated volume. "

01/01/2018 - "Improved survival of patients with spinal bone metastases has resulted in an increased number of referrals for retreatment and repeat reirradiation. "

01/01/2010 - "RESULTS: Randomized trials and meta-analyses demonstrated that single-fraction radiotherapy with 1 × 8 Gy is as effective for pain relief as multi-fraction regimens such as 5 × 4 Gy or 10 × 3 Gy. Re-irradiation for recurrent pain is required more often after single-fraction radiotherapy. "
04/01/2010 - "Re-irradiation for recurrent pain in the irradiated region is required more often after single-fraction radiotherapy than multi-fraction radiotherapy; however, re-irradiation following single-fraction radiotherapy is safe and effective. "
08/01/2019 - "Although the knowledge is limited to a series of a single institution, it shows that re-irradiation is an effective treatment for local control and pain response. "
01/01/2018 - "Although data are limited to single institution series, re-irradiation has consistently been found to be effective with respect to local control (1 year rates range from 66 to 90%) and pain response. "
09/01/2015 - "Reirradiation with CT-guided permanent (125)I seed interstitial brachytherapy is feasible, safe, and effective as pain relief or salvage treatment for patients with recurrent retroperitoneal lymph nodes."
