AIMS AND BACKGROUND To evaluate the effectiveness of tomotherapy-based image-guided radiotherapy (IGRT) on the radiation dose to the cochlea in patients with nasopharyngeal cancer. METHODS AND STUDY DESIGN A retrospective review of five patients undergoing concurrent chemoradiation with tomotherapy for locally advanced nasopharyngeal cancer was performed. RESULTS The mean dose to the right ...

Only oral cavity and pharynx cancers in Vietnam veterans were significantly elevated, although the doubling of risk on nasal/nasopharyngeal cancer in Vietnam veterans is of interest in light of findings in other studies. The continuing excess of soft tissue sarcoma, non-Hodgkin’s lymphoma and Hodgkin’s Disease is consistent with findings in other studies of people exposed to herbicides. The tim...

Nasopharyngeal carcinoma (NPC) is a common form of malignant cancer, for which radiotherapy or chemotherapy are the main treatment methods. Cucurbitacin E (CuE) is a natural compound-based drug which from the climbing stem of Cucumic melo L (Guadi). Previously shown to be an antifeedant as well as a potent chemopreventive agent against several types of cancer. The present study, investigated an...

BACKGROUND Nasopharyngeal carcinoma (NPC) is a major cancer in southern China. Src homology phosphatase-1 (SHP-1) is a tyrosine phosphatase that regulates growth, differentiation, cell cycle progression, and oncogenesis. We determined the clinical significance of SHP-1 expression in the tumours of NPC patients from southern China who were treated with radiotherapy. PATIENTS AND METHODS SHP-1 ...

Nasopharyngeal carcinoma is a cancer with its highest prevalence among the southern Chinese and is rare elsewhere in the world. The main treatment modalities include chemotherapy and radiotherapy. However, tumor chemoresistance often limits the efficacy of nasopharyngeal carcinoma treatment and reduces survival rates. Thus, identifying new selective chemotherapeutic drugs for nasopharyngeal car...

BACKGROUND Previous studies have shown that Epstein-Barr virus (EBV)-encoded latent membrane protein 1 (LMP1) is closely associated with the occurrence and development of nasopharyngeal carcinoma, and can be used as a tumor marker in screening for the disease. Here we report a new methodology based on highly specific and sensitive surface-enhanced Raman scattering (SERS) technology to detect LM...

BACKGROUND AND PURPOSE Our previous nasopharyngeal carcinoma detection study, comparing MR imaging, endoscopy, and endoscopic biopsy, showed that MR imaging is a highly sensitive test that identifies nasopharyngeal carcinomas missed by endoscopy. However, at the close of that study, patients without biopsy-proved nasopharyngeal carcinoma nevertheless had shown suspicious abnormalities on endosc...

Although radiation therapy is effective in the management of patients with early stage nasopharyngeal cancer, a high rate of local-regional failure and distant dissemination is expected in patients with advanced disease. This has prompted studies on the addition of chemotherapy to radiation therapy. Chemotherapy has been used as a neoadjuvant and, less frequently, concomi-tantly with radiation ...
