Active clinical trials for "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.

Radiotherapy is the most appropriate treatment for postoperative recurrent carcinoma cervix. However it is technically difficult to deliver adequate doses of RT due to presence of small intestines in the radiation area; thus disease control rates are poor and complication rates are high with conventional radiotherapy. Use of IMRT and brachytherapy for these cases allows for increasing dose to the tumor while sparing normal structures. It is expected that the use of a combination of IMRT & brachytherapy will achieve higher disease control rates and decrease the complication rates.

This multicentered clinical trial is going to find out the radio-sensitization action of sodium glycididazole in radiochemotherapy for esophageal cancer.

Intensity modulated radiotherapy (IMRT)-based radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Investigators initiated a prospective study to evaluate the efficacy and toxicity of short course preoperative chemoradiotherapy utilizing Intensity Modulated Radiation Therapy (IMRT) in combination with capecitabine in patients with resectable rectal carcinoma.

This laboratory study is using EF5 to evaluate tumor hypoxia in patients with high-grade soft tissue sarcoma or mouth cancer. Using the drug EF5 to measure the oxygen level in tumor cells may help in planning cancer treatment

The purpose of this study is to prospectively evaluate whether combined RFA and TACE (RFA-TACE) result in better survival outcomes than RFA alone in patients with HCC.

RATIONALE: Studying samples of tumor tissue in the laboratory from patients with cancer may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This clinical trial is studying tissue samples in predicting how well chemotherapy and radiation therapy will kill cancer cells in patients with squamous cell carcinoma of the esophagus.

The anti-tumor activity of cetuximab prior to chemoradiotherapy and the safety and tolerability of cetuximab with concurrent chemoradiation will be determined in women with locally advanced or metastatic cervical carcinoma.

Basal like breast carcinoma is a Her2, estrogen receptor (ER) progesterone receptor (PR) negative breast cancer. It is notable for the high level of epidermal growth factor receptor (EGFR) expression in this tumor subtype . Thus the investigators wanted to combine the use of anti EGFR therapy in the form of Erbitux (cetuximab) with the widely used weekly taxol chemotherapy for the treatment of these women. This is a small phase I/II study.

In an effort to identify genetic factors linked to the development of nasopharyngeal cancer (NPC), the researchers identified and sampled 2,394 individuals from Taiwanese families in which two or more relatives had been diagnosed with NPC. Serum from these individuals was tested for three anti-Epstein-Barr virus (EPV) antibodies associated with elevated risk of NPC. Results indicate that apparently healthy individuals from high-risk families have a nearly threefold elevation in their EBV antibody prevalence compared with the general population. However, the clinical implications of this finding are not yet understood. To clarify the implications, the 2,394 unaffected individuals from the multiplex family study will be invited to participate in the current study. Approximately 1,600 individuals are expected to participate. Participants will have an ear, nose, and throat examination to determine if they have occult or symptomatic NPC. Their levels of EBV antibody at the time of initial recruitment will be correlated with NPC detection in the period between initial recruitment and the present study. Participants will also be asked to complete a brief risk factor questionnaire and to donate blood, saliva, a nasopharyngeal swab, nasopharyngeal tissue, and urine for future studies. Currently, no accepted clinical management protocol exists for screening unaffected members from families at high risk of NPC development. Results from this study have the potential to significantly impact the clinical management and follow-up of individuals with a family history of NPC.
