The diagnostic value of 1.5-T diffusion-weighted MR imaging in detecting 5 to 10 mm metastatic cervical lymph nodes of nasopharyngeal carcinoma.

The aim of the study was to prospectively assess the diagnostic accuracy of 1.5 T diffusion-weighted imaging (DWI) for 5 to 10 mm metastatic cervical lymph nodes of patients with nasopharyngeal carcinoma (NPC). All patients with histopathologically confirmed NPC underwent DWI with 2 b values of 0 and 800 s/mm were enrolled.

[Relationship between expression of decoy receptor 3 and apoptosis in hepatocellular carcinoma].

Objective: To study the expression of decoy receptor 3 (DcR3) and its relationship with apoptosis and prognosis in hepatocellular carcinoma (HCC).

Methods: The expression of DcR3 protein in 43 cases of HCC and 16 cases of non-cancerous liver (including cirrhotic liver tissue and normal liver tissue adjacent to cavernous hemangioma) was studied by immunohistochemistry (using EnVision method). The status of apoptosis was evaluated by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL) technique.

[Expression of DeltaNp63 protein in nasopharyngeal carcinoma and its significance].

Background & Objective: The molecular etiology of nasopharyngeal carcinoma is currently unknown. It was reported that DeltaNp63 is dominant-negative toward transactivation of p53, and associated with the malignant hyperplasia and dedifferentiation of the squamous cells. This study was designed to investigate the expression and significance of DeltaNp63 protein in NPC tissues.
