Multicenter StudyImpact of anatomical location on value of CT-PET co-registration for delineation of lung tumors.
To derive guidelines for the need to use positron emission tomography (PET) for delineation of the primary tumor (PT) according to its anatomical location in the lung. ⋯ Using PET for PT delineation is mandatory to decrease interobserver variability in the hilar region, heart, great vessels, pericardium, mediastinum, and/or the region associated with atelectasis; however it is not essential for delineation of PT surrounded by lung or visceral pleura, without venous invasion or extension to the chest wall.

Multicenter Study Comparative StudySurgical resection followed by whole brain radiotherapy versus whole brain radiotherapy alone for single brain metastasis.
To compare the outcome of surgical resection followed by whole brain radiotherapy (WBRT) with WBRT alone in patients treated for single brain metastasis. ⋯ In patients with a single brain metastasis, the addition of resection to WBRT improved survival, local control at the original metastatic site, and control within the entire brain, but did not prevent the development of new brain metastases distant to the original site.
