A method to reconstruct and apply 3D primary fluence for treatment delivery verification.
In this study, a method is reported to perform IMRT and VMAT treatment delivery verification using 3D volumetric primary beam fluences reconstructed directly from planned beam parameters and treatment delivery records. The goals of this paper are to demonstrate that 1) 3D beam fluences can be reconstructed efficiently, and 2) quality assurance (QA) based on the reconstructed 3D fluences is capable of detecting additional treatment delivery errors, particularly for VMAT plans.

The Society of Thoracic Surgeons lung cancer resection risk model: higher quality data and superior outcomes.
The researchers updated the lung cancer resection risk model utilizing the Society of Thoracic Surgeons General Thoracic Surgery Database (GTSD) with a larger and more contemporary cohort. Risk factors from the prior lung cancer resection model were refined, and new risk factors such as prior thoracic surgery were identified. They concluded that operative mortality and complication rates were low for lung cancer resection among surgeons participating in the GTSD.

Lung cancer resection at hospitals with high vs low mortality rates.
The objective of this study was to evaluate perioperative outcomes in patients who underwent lung cancer resection at high-mortality hospitals [HMHs] and low-mortality hospitals [LMHs]) in order to better understand the factors related to differences in mortality rates after lung cancer resection. It concluded that failure-to-rescue rates are higher at HMHs, which may explain the large differences between hospitals in mortality rates following lung cancer resection.

Correlation between the international consensus definition of the Cancer Anorexia-Cachexia Syndrome (CACS) and patient-centered outcomes in advanced non-small cell lung cancer.
The researchers applied the recently posed weight-based international consensus CACS definition to a population of patients with advanced non-small cell lung cancer (NSCLC) and explored its impact on patient-reported outcomes. They concluded that it is useful in identifying patients with advanced NSCLC who are likely to have significantly inferior survival and who will develop more precipitous declines in physical function and QOL.
