Morten Høyer
Stereotactic body radiation therapy (SBRT) is a potential treatment option for patients who develop a relapse within or marginal to a previously irradiated volume, but it seems underused because of sparse knowledge on the efficacy and morbidity related to the treatment. Normal tissues often recover some of the damage caused by the primary radiotherapy with time, but the kinetics of recovery is not clearly described in the literature. There is a growing number of publications on SBRT reirradiation, but the literature consists mainly of retrospective cohort studies...

INTRODUCTION: Mastectomy is the current standard of care for ipsilateral breast tumor recurrences after prior whole breast irradiation (WBI). We report our single-institution experience with breast-conserving surgery (BCS) followed by intraoperative radiotherapy (IORT) as an alternative to salvage mastectomy for new or recurrent breast cancers that develop in the setting of prior thoracic radiation. METHODS: We performed an IRB-approved retrospective review of patients treated with breast IORT between September 2013 and November 2016...

BACKGROUND: Local recurrence following definitive treatment for pancreatic adenocarcinoma is common and can be associated with significant morbidity and mortality. Retreatment options for these patients are limited. Proton beam reirradiation (PRT) may limit dose and toxicity to previously irradiated normal tissues in patients without evidence of metastatic disease. METHODS: Between 8/2010-2/2015, 15 patients with isolated, locally-recurrent pancreatic cancer were treated with PRT...

Isolated local relapse after prostate cancer radiotherapy corresponds to 40% of biochemical failure. The management of these relapses is not well defined. Several strategies are available including surgery, high-intensity focused ultrasounds (HIFU), cryotherapy and reirradiation. Radical prostatectomy is the historical approach; biochemical control is obtained in 50 to 80% at 5 year. However, morbidity is higher after irradiation than as a first line treatment. Some limited series of HIFU and cryotherapy have been published with interesting results, but again the risk of urinary and rectal toxicity is high...

The question whether a reirradiation is possible, with either curative of palliative intent, is a frequent issue and a true therapeutic challenge, in particular for a critical organ sensitive to cumulative dose, such as the spinal cord. Preclinical experimental data, based on debatable models that are hardly transferable to patients, suggest that there is a possibility of reirradiation, beyond the classical threshold for dose constraints, taking into account the "time-dose factor". Although the underlying biological mechanisms are however uncertain, scarce clinical data seem to confirm that the tolerance of spinal cord to reirradiation does exist, provided that a particular attention to total dose is given...

PURPOSE: Reirradiation of thoracic malignancies is a treatment challenge, with concerns for toxicity and the inability to deliver definitive doses. Intensity modulated proton therapy (IMPT) may allow safe delivery of a higher dose of radiation to the tumor while minimizing toxicities. METHODS AND MATERIALS: Between 2011 and 2016, 27 patients who received IMPT for reirradiation of thoracic malignancies with definitive intent were retrospectively analyzed. Patients were included if they received a prior thoracic radiation course...

PURPOSE: The therapeutic ratio of reirradiation for recurrent or second primary (RSP) squamous carcinoma of the head and neck may be improved in the intensity modulated radiation therapy (IMRT) era. However, patient selection for reirradiation remains challenging. We performed a multi-institution cohort study to investigate modern outcomes after IMRT-based reirradiation and to identify prognostic subgroups. PATIENTS AND METHODS: Patients with RSP squamous carcinoma originating in a previously irradiated field (≥40 Gy) who underwent reirradiation with IMRT (≥40 Gy re-IMRT) were included...

Locoregional relapse in previously irradiated region for head and neck tumours is associated with a bad locoregional and distant prognosis. Reirradiation might be exclusive, or feasible in addition with surgery and/or chemotherapy, according to histopronostic factors. Data show that reirradiation is feasible with some severe toxicity due to the bad prognosis of this situation. Hyperfractionnated regimen with split course or normofractionnated regimen without split course are possible with similar efficacy. If tumour size is small, stereotactic ablative radiotherapy may be considered, and if the treatment centre has proton therapy, it could be proposed because of better organs at risk sparing...

Delivering an adequate and homogenous dose to a large volume of recurrent cutaneous disease can be challenging even with modern techniques. Here, the authors describe a 3-isocenter hybrid electron and rapid arc photon radiation treatment plan to provide optimal tumor coverage to an extensive recurrence of inflammatory breast carcinoma. This approach allowed for homogeneous treatment of a large volume while effectively modulating dose to previously irradiated tissue and minimizing dose to the underlying heart, lungs and brachial plexus...

PURPOSE: The purpose of this study is to illustrate the historical development of reirradiation during several decades of the 20th century, in particular between 1920 and 1960. METHODS AND MATERIALS: We chose the format of a narrative review because the historical articles are heterogeneous. No systematic extraction of baseline data, treatment details, or follow-up care was possible in many cases. RESULTS: Both hematological malignancies and solid tumors were treated with a second course of radiation therapy, and indications included local relapse, regional nodal recurrence, and second primary tumors developing in a previously treated region...
