Intraoperative radiotherapy (IORT) is a technique that involves precise delivery of a large dose of ionising radiation to the tumour or tumour bed during surgery. Direct visualisation of the tumour bed and ability to space out the normal tissues from the tumour bed allows maximisation of the dose to the tumour while minimising the dose to normal tissues. This results in an improved therapeutic ratio with IORT. Although it was introduced in the 1960s, it has seen a resurgence of popularity with the introduction of self-shielding mobile linear accelerators and low-kV IORT devices, which by eliminating the logistical issues of transport of the patient during surgery for radiotherapy or building a shielded operating room, has enabled its wider use in the community.Electrons, low-kV X-rays and HDR brachytherapy are all different methods of IORT in current clinical use. Each method has its own unique set of advantages and disadvantages, its own set of indications where one may be better suited than the other, and each requires a specific kind of expertise.IORT has demonstrated its efficacy in a wide variety of intra-abdominal tumours, recurrent colorectal cancers, recurrent gynaecological cancers, and soft-tissue tumours. Recently, it has emerged as an attractive treatment option for selected, early-stage breast cancer, owing to the ability to complete the entire course of radiotherapy during surgery. IORT has been used in a multitude of roles across these sites, for dose escalation (retroperitoneal sarcoma), EBRT dose de-escalation (paediatric tumours), as sole radiation modality (early breast cancers) and as a re-irradiation modality (recurrent rectal and gynaecological cancers).This article aims to provide a review of the rationale, techniques, and outcomes for IORT across different sites relevant to current clinical practice.

Interstitial BT with or without EBRT results in excellent outcomes. Radical BT alone, when used judiciously, results in excellent local control and function with minimal treatment-related morbidity.

Purpose The coronavirus disease 2019 (COVID-19) pandemic has propelled health care workers to the front lines against the pandemic. In addition to anxiety related to infection risks, trainees have the additional burden of learning and career planning while providing care in an uncertain and rapidly changing environment. We conducted a survey to evaluate the practical and psychosocial impact on radiation oncology fellows during the first month of the pandemic. Methods and Materials A 4-part survey was designed and distributed to the fellows in our program. The survey was designed to evaluate the impact of the pandemic on scope of activity and well-being (“Impact on You”) and to identify key lessons learned and social factors (“About You”) using Likert scales and open-ended response options. The survey included items from the Oldenburg Burnout questionnaire. Results A total of 17 participants (71%) responded to the survey. Although there was a significant reduction in the mean time spent on in-person clinics (13.5 h/wk [pre-COVID] vs 9.3 h/wk [3 weeks into the COVID emergency response]; P = .002), this was replaced by virtual consults and other COVID-related activities. The proportion of respondents demonstrating features of burnout in the domains of “disengagement” and “exhaustion” was 71% and 64%, respectively. However, there was also evidence of resilience, with 47% respondents “feeling energized.” Top “concerns” and “negative changes” identified related to learning, infection risk and safety, patient care, coping, and concerns about their home country. Top “positive changes” highlighted include work culture, appreciation for leadership caring for the team, the insistence on evidence to guide change, and the implementation of virtual health care. Conclusions Negative impact needs to be anticipated, acknowledged, and managed. We anticipate understanding the positives that have emerged under these extraordinary circumstances is the “silver lining” of the pandemic, giving us tools and the best leverage to plan for the future.
