Selection of sublobar resection for c-stage IA non-small cell lung cancer based on a combination of structural imaging by CT and functional imaging by FDG PET.

Purpose: The purpose of this study was to establish criteria for the indication of sublobar resection or lobectomy in cT1N0M0 non-small cell lung cancer (NSCLC), based on information from both computed tomography (CT) and fluorodeoxyglucose positron emission tomography (FDG PET).

Materials And Methods: A total of 248 cT1N0M0 NSCLC tumors treated surgically were subjected to high-resolution or thin-slice CT (HR/TSCT) study, and 99 of these tumors were also subjected to FDG PET study. Four types of data were collected: (1) tumor size based on HR/TSCT (0-10 mm, 11-20 mm or 21-30 mm); (2) percentage of ground-glass opacity (GGO) region (GGO type or solid type); (3) pathological type (invasive cancer [INVC] or non-INVC [NINVC]); (4) FDG uptake in the tumor (grades 0, 1, and 2).

Radical excision of thymic adenocarcinoma with selective cerebral perfusion.

Most cases of thymic carcinoma have some invasion to neighboring organs when diagnosed, and it is generally difficult to completely remove. We adopted selective cerebral perfusion as a cerebral protection and successfully performed resection of a thymic adenocarcinoma that involved the superior vena cava, left brachiocephalic vein, right brachiocephalic artery and vein, and left common carotid artery in a 47-year-old woman. Even if multiple great vessels were involved by mediastinal malignant tumor, complete resection with selective cerebral perfusion could be safely performed.
