Podcasts about reirradiation

Editor-in-Chief, Robert Amdur, MD, discusses using SBRT dose schedules to re-irradiate large volume recurrences of locally advanced Non-Small Cell Lung Cancer that has progressed following high-dose radiotherapy with conventional fractionation. The discussion is based on a paper published in the May 2024 issue of PRO titled "Thoracic Reirradiation with Stereotactic Body Radiation Therapy (SBRT) for Recurrent Advanced Non-Small Cell Lung Cancer (NSCLC)” (2024, Issue 3, May/June, PMID 38387781).

Editor-in-Chief Dr. Sue Yom is joined this month by co-host Dr. Danielle Margalit, the Red Journal's Head and Neck Section Editor and Associate Professor of Radiation Oncology at Harvard Medical School. Guests are Dr. Adam Garden, Professor of Radiation Oncology at UT MD Anderson Cancer Center, who is the first author of an article in this month's issue, "Final Report of NRG Oncology RTOG 0022: A Phase 1/2 Study of Conformal and Intensity Modulated Radiation for Oropharyngeal Cancer"; Dr. Michelle Echevarria, Assistant Member in the Department of Radiation Oncology at Moffitt Cancer Center and first author of another article printing this month, "Phase 1 Dose Escalation of Stereotactic Body Radiation Therapy and Concurrent Cisplatin for Reirradiation of Unresectable, Recurrent Squamous Cell Carcinoma of the Head and Neck"; and Dr. Robert Chin, Associate Professor at UCLA Radiation Oncology and supervising author of a third article in the October issue, "High Recurrence for HPV-Positive Oropharyngeal Cancer With Neoadjuvant Radiation Therapy to Gross Disease Plus Immunotherapy: Analysis From a Prospective Phase Ib/II Clinical Trial."

NCIC SC.20 demonstrates that a second course of radiation for painful osseous metastases significantly improves patients quality of life and function.

Background and purpose: The aim of the present analysis was to assess the feasibility, toxicity, and the tumor control of reirradiation as a salvage treatment for progressive pediatric non-pontine high-grade gliomas (HGG). Patients and methods: The database of the Reference Center for Radiation Oncology of the German HIT (HIT = German acronym for brain tumor) treatment network for childhood brain tumors was screened for children who were reirradiated for progressive non-pontine HGG. Results: We identified eight patients (WHO grade III: n = 5; WHO grade IV: n = 3) who underwent reirradiation between April 2006 and July 2012. Median age was 13.5 years at primary diagnosis and 14.8 years at first progression. All patients initially underwent surgery (incomplete resection, n = 7; biopsy, n = 1) followed by radiochemotherapy. Relapses occurred inside (n = 2), at the margin (n = 4), and outside of the preirradiated area (n = 2). In all patients, reirradiation was tolerated well without significant acute toxicity. Temporary clinical improvement and tumor regression on magnetic resonance imaging (MRI) following reirradiation was reported (n = 3). However, all patients finally died by disease progression. Median survival time was 26.2 months from initial diagnosis and 11.4 months after first progression. Median time interval between initial radiotherapy and first reirradiation was 9.0 months. In six patients, all macroscopic tumor deposits were reirradiated. In these patients, median progression-free (overall) survival from the start of reirradiation was 2.4 (4.6) months. Conclusion: Our analysis, although based on a limited patient number, suggests that reirradiation of progressive non-pontine HGG is feasible in children. Benefit in terms of quality of life and/or survival needs to be assessed in a prospective and ideally in a randomized manner.
