Practical radiation oncology

Although palliative care is recognized as integral to oncology care, limited data exist regarding the extent to which palliative care training is incorporated into radiation oncology residency training in the United States. We aim to characterize US radiation oncology residents' perceived palliative care educational needs and experience to guide future palliative oncology educational interventions. ⋯ Although the majority of residents view palliative care as an important competency for radiation oncologists, a majority perceived their educational training as inadequate across multiple domains. Most residents desire further palliative oncology care training. These findings suggest efforts should be made to improve palliative care education during radiation oncology training.

Medical students often choose to pursue a career in radiation oncology with limited meaningful exposure to the field. We previously identified factors that were most influential to an applicant's rank list order. Here, we sought to assess if residency graduates had differing views regarding those factors. We also polled recent graduates' attitudes of the current job market. ⋯ After training, residency graduates place higher value on factors in residency that can directly improve job procurement. This finding is more common among more recent graduates, potentially a result of the perception of a tightening job market with too many radiation oncologists in training.

Radiation therapy is one of the mainstays of treatment for painful bone metastases; however, the optimal fractionation and dosing of radiation for a given patient and disease characteristics are still subject to debate. ⋯ Our data demonstrate that selection of radiation fractionation schedules should take into account primary tumor type, KPS, and age, and we have generated an RPA model including these factors to help guide decision making. We also found that shorter fractionation schedules are as effective as longer fractionation schedules for pain control, regardless of primary tumor type.

Radiation therapy (RT) for gastric mucosa-associated lymphoid tissue (MALT) lymphoma is challenging because of variation in the stomach's position, size, and shape. We investigated the interfractional changes in stomach location, consequent dosimetric effects, and impact of daily computed tomography image guidance RT (CT-IGRT). ⋯ Substantial interfractional variation in stomach volume was observed, despite treatment with breath-hold and restriction of oral intake. Daily CT-IGRT improved target coverage, enabling excellent coverage despite the use of small PTV margins.
