Filter by:Translocator protein (TSPO) is a intracellular protein that is found primarily in the outer membrane of the mitochondria that is encoded by the TSPO gene. It has been found that TSPO expression in the skin correlates with cell proliferation and differentiation. Many studies have shown that TSPO overexpression in solid malignancies such as in ovarian cancer, colon cancer, and others, was also found to correlate with more aggressive cancer behavior. Working Hypothesis and Aims: Previous studies described an aberrant expression of TSPO levels in solid malignancies as compared to normal tissues. It is assumed that this aberration can be found in cuntaneous malignancies as well. The occurrence of this aberration may lead to the understanding of the mechanism of TSPO involment in the cutaneous malignancy, and in malignancies in general. Methods: The study will be carried out on surgically resected skin lesions suspected to SCC or BCC, which will be removed as part of the surgical routine treatment. The excision will be made in elliptic shape including the lesion and a part of normal skin surrounding it. A sample will be taken from the central part of the lesion and from the external extremity of the normal tissue. Western Blot will be conducted to detect the expression of TSPO. Binding activity with the TSPO specific ligandwill also be determined. Expected Results: We expect to observe either (a) a higher level of TSPO expression and a lower binding activity in malignant tissue compared with healthy control tissue or (b) a higher level of TSPO expression and a lower binding activity in malignant tissue compared with healthy control tissue. Importance: Until today, only a very small number of studies have examined TSPO in cutaneous malignancies, and these only examined TSPO expression. Our study will also measure the binding activity of TSPO in cutaneous malignant tissues compared to normal tissues
This phase II trial is studying cisplatin or nedaplatin combine with IMRT to evaluate which one is better efficacy and security in nasopharyngeal carcinoma.
30% of renal cell carcinoma patients have metastases, mostly in lung, liver and bones at the time of diagnosis. Because of poor response to radiation therapy or chemotherapy, several studies have been initiated to find alternative therapeutic options. Cytokine induced killer cells(CIK) are an unique population of cytotoxic T lymphocytes with a characteristic CD3+ CD56+ phenotype; they can be generated from cytokine cocktail-induced peripheral blood mononuclear cells (PBMC). CIK cells represent strong anti-tumor cytotoxicity in vitro and in vivo. Interestingly,the anti-tumor activity of CIK cells can be enhanced by incubation with dendritic cells (DC), which are the most potent antigen (Ag)-presenting cells. The purpose of this study was to evaluate the clinical efficacy of DC-activated CIK cell treatment following regular therapy and the effects of this therapy on immune responses in patients with renal cell carcinoma after surgery.
Endoscopic thyroidectomy has been used to treat thyroid diseases in China. However, whether this technique is rational to treat thyroid carcinoma is still in controversy. The diagnosis of thyroid carcinoma is predominantly made according to intra-operative frozen section pathological examination in China. In this research, the investigators want to compare clinical index (blood loss, operation duration, number of lymph nodes dissected, complication rates, etc) between patients underwent endoscopic thyroidectomy ( total thyroidectomy) and those underwent conversion to open procedure. The investigators want to evaluate the technical feasibility of endoscopic thyroidectomy for treating thyroid carcinoma.
The purpose of this study is to determine whether an addition of cetuximab to carboplatin/paclitaxel can improve efficacy in comparison to carboplatin/paclitaxel in patients with carcinoma of unknown-primary.
The purpose of this study is to evaluate 3 imaging techniques and their associations : MRI, CTscanner and enhanced contrast ultrasound for the diagnosis of small (< 3 cm) hepatocellular carcinoma for patients with cirrhosis.
The primary objective of this study is to determine the response rate, tolerance and overall survival in patients with stage III, IVa, IVb NPC treated with neoadjuvant chemotherapy (TPF regimen) and concurrent chemoradiation. Secondary objectives of the study are to evaluate the distant metastases free survival, and disease-free survival of patients with stage III,IVa, IVb NPC treated with this regimen. The third objective of this study is to evaluate who may benifit from this treatment regimen.
The purpose of this study is to determine recurrence rates of nodular Basal Cell Carcinomas on the face removed with curettage and electrodessication (cautery) followed by application of Imiquimod cream to the base and further to achieve lower recurrence rates than after treatment with curettage and electrodessication alone.
