Image analysis in posttreatment non-small cell lung cancer surveillance: specialists' interpretations reviewed by the thoracic multidisciplinary tumor board.

Background: Data show that the initial specialist's image interpretation and final multidisciplinary tumor board (MTB) assessment can vary substantially in the pretherapeutic cancer setting. The aim of this analysis was to investigate the concordance of the specialist's and MTB's image interpretations in patients undergoing systematic posttreatment lung cancer image surveillance.

Methods: In the initial prospective study, lung cancer patients who had received curative-intent treatment were randomly assigned to undergo either contrast-enhanced computed tomography (CE-CT) or integrated 18-fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT).

Comparing Two Imaging Methods for Follow-Up of Lung Cancer Treatment: A Randomized Pilot Study.

Background: Scientific data on the image modality to be used in postcurative treatment surveillance of non-small cell lung cancer patients are scarce. This prospective randomized pilot trial compared the performance of integrated F-fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) and contrast-enhanced computed tomography (CE-CT).

Methods: After termination of curative-intent treatment, patients were randomly assigned to the PET-CT or the CE-CT group.

Significant improvement of olfactory performance in sleep apnea patients after three months of nasal CPAP therapy - Observational study and randomized trial.

Objectives: The olfactory function highly impacts quality of life (QoL). Continuous positive airway pressure is an effective treatment for obstructive sleep apnea (OSA) and is often applied by nasal masks (nCPAP). The influence of nCPAP on the olfactory performance of OSA patients is unknown.
