The paper reviews evidence that before any change in diabetics' fundi, changes occur to blood flow, ERG and visual functions. In the case of colour vision and contrast sensitivity, the changes are partially reversed by breathing oxygen, and therefore are the result of retinal hypoxia. There are also other evidences that hypoxia is a major factor in the(More)
BACKGROUND Upfront tyrosine kinase inhibitor (TKI) has proved effective for selective advanced lung cancer patients in Taiwan. We hypothesized that early integration of radiotherapy during TKI treatment would decrease the chance of drug resistance and prolong progression-free survival (PFS). METHODS This study included 25 patients with stage IIIb or IV(More)
PURPOSE We report our preliminary experience of combining sunitinib and helical tomotherapy in patients with advanced HCC. METHODS AND MATERIALS Records of patients with advanced hepatocellular carcinoma (HCC) treated with helical tomotherapy and sunitinib after radiation therapy (RT) from March 2007 to August 2008 were retrospectively reviewed. We report(More)
Interleukin-2 (IL-2) and granulocyte-macrophage colony stimulating factor (GM-CSF) facilitate the maturation and functioning of injected DC. We developed a method of in situ electroporation using IL-2 and GM-CSF genes (EGT/cytokines), followed by intra-tumoral (i.t.) immature DC to determine the immune response at the tumor site using prostate-specific(More)
Surface-Enhanced Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (SELDI-TOF-MS) is a frequently used technique for cancer biomarker research. The specificity of biomarkers detected by SELDI can be influenced by concomitant inflammation. This study aimed to increase detection accuracy using a two-stage analysis process. Sera from 118 lung cancer(More)
The treatment of intratumoral dentritic cells (DCs) commonly fails because it cannot evoke immunity in a poor tumor microenvironment (TME). Modulated electro-hyperthermia (mEHT, trade-name: oncothermia) represents a significant technological advancement in the hyperthermia field, allowing the autofocusing of electromagnetic power on a cell membrane to(More)
Bone is one of the most common metastatic sites of breast cancer. We present a case of breast cancer with bone metastases and the patient was evaluated by FDG-PET/ CT and a bone scan. The PET scan had a negative finding, but both bone and CT scans detected bone metastases. In general, FDG-PET has greater specificity and good sensitivity for detecting bone(More)
The introduction of beam intensity control concept in current radiotherapy techniques has increased treatment planning complexity. Thus, small-field dose measurement has become increasingly vital. Polymer gel dosimetry method is widely studied. It is the only dose measurement tool that provides 3D dose distribution. This study aims to use an(More)
OBJECTIVE To present an extremely rare case of squamous cell carcinoma of the ureter with cutaneous metastases. CLINICAL PRESENTATION AND INTERVENTION A case is presented involving a 67-year-old woman presenting with a clinical history of squamous cell carcinoma of the ureter and who had undergone a nephro-ureterectomy with a bladder cuff excision in May(More)
