Practice Guideline
Practice recommendations for lung cancer radiotherapy during the COVID-19 pandemic: An ESTRO-ASTRO consensus statement.
The COVID-19 pandemic has caused radiotherapy resource pressures and led to increased risks for lung cancer patients and healthcare staff. An international group of experts in lung cancer radiotherapy established this practice recommendation pertaining to whether and how to adapt radiotherapy for lung cancer in the COVID-19 pandemic. ⋯ This joint ESTRO-ASTRO practice recommendation established pragmatic and balanced consensus recommendations in common clinical scenarios of radiotherapy for lung cancer in order to address the challenges of the COVID-19 pandemic.

To interrogate inter-observer variability in gross tumour volume (GTV) and clinical target volume (CTV) delineation specific to the treatment of sacral metastases with spinal stereotactic body radiation therapy (SBRT) and develop CTV consensus contouring recommendations. ⋯ Consensus recommendations for CTV target delineation specific to sacral metastases treated with SBRT were established using expert contours. This is a critical first step to achieving standardisation of target delineation practice in the sacrum and will serve as a baseline for meaningful pattern of failure analyses going forward.

Multicenter Study
Multi-institutional validation of brain metastasis velocity, a recently defined predictor of outcomes following stereotactic radiosurgery.
Brain metastasis velocity (BMV) is a prognostic metric that describes the recurrence rate of new brain metastases after initial treatment with radiosurgery (SRS). We have previously risk stratified patients into high, intermediate, and low-risk BMV groups, which correlates with overall survival (OS). We sought to externally validate BMV in a multi-institutional setting. ⋯ This multi-institutional dataset validates BMV as a predictor of OS following initial SRS. BMV is being utilized in upcoming multi-institutional randomized controlled trials as a stratification variable for salvage whole brain radiation versus salvage SRS after DBF.

Systemic therapy such as sorafenib is the standard for Barcelona Clinic Liver Cancer (BCLC) stage C hepatocellular carcinoma (HCC); however, the survival benefits are modest especially for HCC with macroscopic vascular invasion (MVI). Transarterial chemoembolization (TACE) plus external beam radiotherapy (RT) is an alternative treatment to sorafenib, with favorable clinical results. We evaluated the outcomes of respiratory-gated RT and TACE in treatment-naïve BCLC stage C HCC patients with MVI and proposed a subclassification model. ⋯ TACE plus RT is an effective and safe treatment for HCC with MVI and could be considered a first-line treatment option. The subclassification scheme accurately predicted the prognosis of these patients and may be useful for tailored treatment.
