SBRT re-irradiation after prior SBRT in pancreatic cancer —outcomes and a focus on stomach and bowel toxicity
ConclusionSBRT after prior SBRT for pancreatic cancer is a reasonably safe and efficacious treatment that leads to durable local control and reasonable survival. Retreatment of the duodenum and stomach with a D0.03cc and D1cc of at least 40 Gy may be safe, although more data is needed. (Source: Journal of Radiation Oncology)

Feasibility of simulation contrast-enhanced computed tomography (CECTSim) of the head and neck region to detect early nodal recurrence in postoperative oral squamous cell carcinoma in a resource-constrained setup
ConclusionCECTSim may be helpful in the detection of EPNR in OSCC and may preclude the need for additional imaging before the start of PORT. CECTSim may also facilitate the appropriate determination of the radiation volume and appropriate dose to the corresponding target volume. (Source: Journal of Radiation Oncology)

Indirect evaluation of pretreatment imaging protocols and their clinical impact on patient dose delivery in radiotherapy
ConclusionThis study plays a vital role in establishing optimum pretreatment imaging protocols in busy clinics. Three days a week imaging protocol is the best suit protocol found with minimal deviation and ample implementation feasibility. This study proposed an opinion pertaining to the revision of setup margin formula in order to accommodate variation due to imaging techniques and frequency of imaging attempted during radiotherapy.

Impact of lung tumor motion on dose delivered to organ at risk in lung stereotactic body radiation therapy
ConclusionThe dose received by the OARs depends on the amplitude of tumor motion and is relative to the OAR ’s location and motion, due to patient respiration and heart contribution. (Source: Journal of Radiation Oncology)

Efficacy of palliative SBRT in local control of sarcoma
ConclusionOur institutional experience provides encouraging evidence of the feasibility of SBRT in the palliation of sarcoma. Poor overall survival is a substantial competing risk in these patients. Further studies will be required to identify the ideal dose and fractionation across histological subtypes. Prospective clinical trials may be warranted. (Source: Journal of Radiation Oncology)

Early detection of SARS-CoV-2 from staging PET-CT
ConclusionIn the COVID-19 era, oncologists obtaining routine staging imaging should have high diagnostic suspicion for subclinical SARS-CoV-2 infection. To avoid precipitating severe pneumonia and hospitalization, multidisciplinary discussion with risk-benefit analysis is recommended before initiating immunosuppressive therapies such as chemoradiation.

Dosimetric comparison of three-dimensional conformal radiotherapy and static and dynamic intensity-modulated radiotherapy for the treatment of early-stage glottic cancer
ConclusionThe D-IMRT and S-IMRT techniques allowed more homogeneous dose distributions in PTV. Considering the dose to OAR, S-IMRT was more appropriate rather than 3DCRT and D-IMRT. (Source: Journal of Radiation Oncology)

An observational study of post-operative volumetric modulated arc radiotherapy (VMAT) of breast cancer by immobilizing patients on All-in-One (AIO ™) solution breast and lung board without using thermoplastic mask: risk of collision of gantry with couch exists if acquisition of Cone Beam Computed Tomography (CBCT) is attempted for set-up verification
ConclusionPerforming CBCT for generating 3D images for computed tomography (CT) reconstruction may not be practical for patient set-up verification of post-operative radiotherapy of unilateral breast cancer patients positioned supine on breast and lung board. (Source: Journal of Radiation Oncology)

Peer review program to enhance treatment planning quality assurance for community radiation oncologists
ConclusionA two-step QA program was considered highly valuable by all participants allowing easily implanted mechanisms for standardization, higher case volume, and shared educational resources for small academic satellite CROs who are faced with the challenge of caring for a diverse community cancer population. Feasibility suggests the model could serve as a model for other CRO. (Source: Journal of Radiation Oncology)
