Lung cancer reirradiation: Exploring modifications to utilization, treatment modalities and factors associated with outcomes.

BACKGROUND: Patients treated for lung cancer (LC) often experience locoregional failure after initial treatment. Due to technological advances, thoracic reirradiation (re-RT) has become a viable treatment option. We sought to investigate the use of thoracic re-RT in LC patients over a time period characterized by technological advances in a large, multi-center cohort. METHODS AND MATERIALS: LC patients treated with thoracic re-RT in two University Hospitals from 2010-2020 were identified. Clinical variables and RT data were extracted from the medical records and treatment planning systems. Overall survival (OS) was calculated from the last day of re-RT until death or last follow up. RESULTS: 296 patients (small cell LC n=30, non-small cell LC n=266) were included. Three-dimensional conformal radiation therapy was the RT technique used most frequently (63%), and 86% of all patients were referred for re-RT with palliative treatment intent. During the second half of the study period, the use of thoracic re-RT increased in general, more patients received curative re-RT, and there was an increased use of stereotactic body radiation therapy (SBRT). Median time between initial RT and re-RT was 18 months (range 1-213 months). Only 83/296 patients had combined treatment plans that allowed for registration of combined doses to organs at risk (OAR). Most of the combined doses to OAR were below recommendations from guidelines. Multivariate analysis showed superior OS (p<0.05) in patients treated with curative intent, SBRT or intensity modulated radiation therapy or had excellent performance status prior to re-RT. CONCLUSIONS: The use of re-RT increased in the second half of the study period, although 2020 did not follow the trend. The use of SBRT and IMRT became more frequent over the years, yet the majority received palliative re-RT. Combined dose plans were only created for one third of the patients.

Identifying radiation therapists' perceptions of potentially triggering aspects of care for survivors of sexual violence undergoing radiotherapy.

INTRODUCTION: Research shows that for survivors of sexual violence (SV), cancer procedures can be retraumatizing due to perceived similarities to the original SV. To date, there is no training program designed specifically for the radiation therapist (RTT) on how to deliver care sensitively to survivors of SV. A key component of sensitive practice is working with patients to identify and develop strategies to manage situations that could be triggering. The goal of this study was to understand the RTT recognition of potential sensory/environmental, relational, and mixed triggers in radiation oncology settings. METHODS: This quantitative research study conducted a secondary analysis on RTT responses to a learning activity from an online cancer education training program. The first section of the activity asked trainees to identify two potential triggers in a brachytherapy video, and the second portion of the activity asked trainees to describe two potential triggers in their own work. RESULTS: Descriptive statistics, χ2 tests, and t tests were used to analyze 50 RTT responses. RTTs tended to identify different types of triggers depending on the question (brachytherapy video vs. self-reflection). Data indicated that despite a lack of formal didactic training in trigger management, RTTs could identify triggers, and were most likely to recognize "mixed" type triggers. DISCUSSION: Triggers identified are consistent with past research on childhood sexual abuse survivors' healthcare retraumatization in obstetrics and gynecology, and cancer care. As in past research, invasive techniques, and situations where the patient was in a submissive position were identified as triggering aspects of care. It is interesting to note when reflecting on their own practice, the least identified triggers all fell under the environmental/sensory trigger category. RTTs may not fully appreciate a variety of potential triggers such as sounds of treatment or silence because they are outside of the room administering the beam when the machine is delivering treatment. Thus, they may not hear certain sounds or silence during their daily routine. CONCLUSIONS: Relatively few trainees identified sensory/ environmental triggers (e.g., restricted visibility and sounds of treatment, including silence) when reflecting on their own practice, which could potentially reduce their likelihood of helping patients minimize the impact of (or avoid) such triggers. Future research should identify a comprehensive list of triggers and then develop a training specific to the RTT focused on identifying environmental/sensory triggers from the perspective of the patient in the often unfamiliar and frightening radiotherapy suite.

The Impact of Interpersonal Skills Training on the Transition to Radiotherapy Student Clerkship.

INTRODUCTION/BACKGROUND: Preparing students for clerkship in a radiation oncology setting requires complex, sensitive, and specific interpersonal skills training. Oncology patients undergoing radiation therapy treatment present with unique needs given the harrow of a cancer diagnosis. Although the radiation therapy profession's credentialing body requires interpersonal skills training, there is little research specific to radiotherapy student communication training across the globe. LITERATURE REVIEW: Searches for relevant literature were conducted and the following themes emerged: transitions to clinical training, value of interpersonal skills and value of interprofessional education. The majority of literature identified supported medical, nursing, physical therapy and physician's assistant education. DISCUSSION: Radiotherapy students often participate in the same undergraduate coursework with various health science disciplines, with a common goal of providing optimal patient care. This diverse classroom of radiation therapy, radiologic technology, and dosimetry students mimic the interdisciplinary team in radiation oncology, preparing students for clerkship in a safe and authentic environment. Interprofessional education serves as a vehicle to enhance the transition from the classroom to the clinic while simulating the alliance of healthcare professionals required for team-based care. CONCLUSION: Interpersonal skills training specific to radiation therapy education is lacking and further limited to research conducted in Canada, New Zealand, and Australia. The gap in research in the United States provides many areas of opportunity.
