FDG PET-CT in non-small cell lung cancer: relationship between primary tumor FDG uptake and extensional or metastatic potential.

Objective: To explore the relationships between primary tumor 18F-FDG uptake measured as the SUVmax and local extension, and nodal or distant organ metastasis in patients with NSCLC on pretreatment PET-CT.

Methods: 93 patients with NSCLC who underwent 18F-FDG PET-CT scans before the treatment were included in the study. Primary tumor SUVmax was calculated; clinical stages, presence of local extension, nodal and distant organ metastases were recorded.

Clinical features and outcome of patients with HIV-negative multicentric Castleman's disease treated with combination chemotherapy: a report on 10 patients.

To investigate the clinical characteristics and outcome of patients with HIV-negative multicentric Castleman's disease (MCD) treated exclusively with combination chemotherapy, and review literature to improve the diagnosis and management of this disease. A retrospective study was performed on the medical records of 10 patients with HIV-negative MCD treated exclusively with combination chemotherapy at one medical institution from May 2004 to April 2012. And relevant clinical, pathological, radiographic, and laboratory data were examined in order to evaluate treatment responses, with symptom onsets and survival period serving as the endpoints of the assessment.
