Clinical analysis of bone metastasis of gastric cancer: incidence, clinicopathological features and survival.

We evaluated the incidence, clinicopathological features, prognostic factors and survival of gastric cancer (GC) with bone metastasis in a single large cancer center in China. Patients with bone metastasis of GC were retrospectively analyzed. Overall survival was estimated using the Kaplan-Meier method.

Preliminary comparison of diffusion-weighted MRI and PET/CT in predicting histological type and malignancy of lung cancer.

Introduction: Emerging evidence shows that diffusion-weighted magnetic resonance imaging (DW MRI) and fluorine 18 fluorodeoxyglucose positron emission tomography/computed tomography ( F-FDG PET/CT) might be useful in predicting histological type and malignancy of lung cancer, and even in specifically detecting the types of gene mutation.

Objective: We assessed whether DW MRI is equivalent to PET/CT in lung cancer diagnosis and evaluation.

Methods: The institutional review board approved this study, and written informed consent was obtained from all patients.

DW MRI at 3.0 T versus FDG PET/CT for detection of malignant pulmonary tumors.

Emerging evidence suggests that diffusion-weighted magnetic resonance imaging (DW MRI) could be useful for tumor detection with N and M staging of lung cancer in place of fluorine 18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT). DW MRI at 3.0 T and FDG PET/CT were performed before therapy in 113 patients with pulmonary nodules.
