Active clinical trials for "Neoplasms"

The performance of multiple minor hepatectomies (MMH) instead of major hepatectomies (MH) in patients with colorectal liver metastases (CLM) is object of debate. We build a study, using the propensity score matched analysis, to compare the short- and long-term outcome of the tow groups of patients.

Recently, targeted next generation sequencing (NGS) platforms have been introduced that allow inexpensive testing for hundreds of mutational hotspots at the same time. A number of additional mutational markers in thyroid cancer have been identified. Highly promising markers associated with tumor prognosis have also been found. This multi-institutional study aims to validate the diagnostic use of mutational markers in thyroid nodules with indeterminate cytology. The proposed hypothesis is that a broad NGS-based genotyping of thyroid nodules using a large panel of mutational markers applied to thyroid FNA samples can provide an accurate cancer risk stratification in thyroid nodules. The performance of the panel will be tested in a multi-institutional double-blind prospective study of FNA samples from thyroid nodules with indeterminate cytology and available surgical outcome

Recently, diffusion-weighted (DW) MR imaging has widened its application on various oncologic applications. Especially, it is expected the DW MRI could provide valuable information about early response evaluation after treatment using rapid apparent diffusion coefficient (ADC) value change. It has demonstrated potential usefulness in response evaluation in the liver tumors after treatments such as transarterial chemoembolization (TACE) and radiation therapy (RT). Furthermore, it is a functional imaging technique that does not require a contrast agent, it can be safely used in patients with renal insufficiency or other medical contraindications for contrast agents. The optimal assessment of early response of RT could provide one of the most important information to prescribe patient and cancer specific RT dose. It might be also important in palliative RT of HCC bone metastasis which is related with painful aggressive mass formation. This study is performed to evaluate the usefulness of DW MRI in early response evaluation after RT for HCC bone metastasis.

The purpose of this study is to determine the clinical value of the novel MRI-techniques DWI and gadofosveset-enhanced MRI for the management of rectal cancer patients.

Studies have shown that different percentages of body fat can alter the way drugs are distributed in the body. This study will use blood samples taken at different time points for patients taking acyclovir to determine if higher body weights affect drug exposure. The information gathered from this study will help understand if patients with higher body weights need a different dosing plan. Patients receiving acyclovir as standard of care will be enrolled into this study. They will have blood draws once before they take acyclovir and 10 times after they take the acyclovir (over a total of 12 hours). These patients will be in the hospital already and will not need to make additional trips back to have blood drawn. A total of about 4-5 tablespoons of blood will be drawn for this study. 7 obese patients and 7 matched, non-obese patients will be enrolled into this study.

Measuring the bioavailability of orally administered curcumin in the tumors of glioblastoma patients.

This is a feasibility study to look for genetic alterations in tissue and blood samples that may be useful in determining what treatments may be useful in the patient's cancer care.

The study aims to: Achieve molecular imaging of MG7 antigen in patients with gastric cancer in vivo using confocal laser endomicroscopy. Compare the results of in vivo MG7-specific molecular imaging with CLE and ex vivo immunohistochemistry .

The objective of the study is to provide proof that a MRI based preoperative radiochemotherapy in patients with locally advanced rectal carcinoma allows limiting RCT to high risk patients without increase of locoregional recurrence rate and decrease of overall survival provided there is a high quality of mesorectal excision.

This research trial is studying biomarkers in tissue samples from young patients with liver cancer. Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.
