Active clinical trials for "Carcinoma"

This is a retrospective study in patients with cancer of the oral cavity, pharynx, and larynx. Imaging exams of these patients will be analyzed with the objective of developing and validating a clinically applicable method for evaluation of cachexia and/or sarcopenia in a patient with head and neck cancer from musculature imaging of the neck. Indeed, the prognostic influence of body composition will be evaluated.

Background: There are about 100 trillion microbial cells in a person s gut. This is called the human gut microbiota. When this is disrupted, it can lead to many diseases. Studies show that the gut microbiota in people with cancer is different than that found in healthy people. Researchers want to study links between the gut microbiota and the immune system in people with a liver disease called hepatocellular carcinoma (HCC). Objective: To study links between gut microbiota and the immune system in people with HCC. Eligibility: People at least 18 years old with HCC. They must be scheduled to have tumors removed by surgery. Design: People having surgery for primary liver tumors at the Mount Sinai Medical Center will be screened for this study. At the initial visit, blood, rectal swabs, urine, and stool will be collected. Participants will answer questions about their medical condition. Before surgery, blood, rectal swabs, urine, and stool will be collected. This will be done at a routine visit. When they have surgery, a piece of liver tissue with the tumor will be collected. This will be sent to the National Cancer Institute for tests. After surgery, blood, rectal swabs, urine, and stool will be collected 3 times. This will be done at routine visits.

The purpose of this study is to determine whether a relationship exists between a previously established diagnosis of endometriosis and the consecutive risk of developing a clear cell or endometrioid ovarian carcinoma. All histopathological records since 1980 with these diagnoses (endometriosis, clear cell and endometrioid ovarian carcinoma) will be reviewed. Cancer registry data will be assessed to investigate differences in survival of women with endometriosis-associated ovarian carcinomas and those ovarian carcinoma patients without previous diagnosis of endometriosis.

A retrospective study to evaluate healthcare cost and resource utilization for patients with metastatic renal cell carcinoma who have been treated with IV or oral agents

A prospective intra-individual study to investigate the diagnostic performance of gadoxetic acid-enhanced MR for the patients with liver cirrhosis using thin-section whole-explant as standard of reference

The research team will develop an intraoperative handheld device for assessing surgical margins during Mohs surgery. The device technology is based on multimodal optical spectroscopy (MMS), combining three optical spectroscopy techniques into one device. The researchers will first acquire proof of concept MMS measurements within the Mohs surgery suite immediately after surgical excision and prior to histological processing. MMS measurements will be acquired directly on the patient from the NMSC excision site. The final outcome of this study will result in the sensitivity and specificity of MMS compared to histopathology during Mohs surgery. These results will allow for the estimation of the potential benefit of an intraoperative margin assessment technique.

This trial assesses current biomarker testing practices for common solid cancers in precision oncology in the community setting. Cancer biomarkers are used for diagnosing the disease, determining prognosis, predicting response to a targeted therapy, or monitoring response to therapy. Testing quality, including accuracy and timeliness, is imperative for correct disease prognosis and identification of patients who may or may not benefit from a targeted therapy. Assessing current biomarker testing practices may help doctors identify gaps and variations in testing as well as on potential ?best practices? that may be informative and generalizable to community oncology programs.

To explore biomarkers predictive of clinical response to Taxane/5-FU/platinum based chemotherapy in esophageal squamous cell carcinoma. To identify negative predictive markers to 5-FU/platinum/Taxane. To elucidate signal transduction pathway attributable to 5-FU/platinum/Taxane resistance. To analyze correlation between the quantity of circulating tumor cells and circulating endothelial cell precursors and treatment response to Taxane/5-FU/platinum based chemotherapy.

This is an expanded access study with ANG1005 treatment for two individual patients from Protocol ANG1005-CLN-03 with WHO Grade III Anaplastic Astrocytoma and WHO Grade III Anaplastic Oligodendroglioma and one individual patient from Protocol ANG1005-CLN-04 with Recurrent Brain Metastases and Leptomeningeal Carcinomatosis.

This is an open-label, non-comparative, multicenter, expanded access study of Vismodegib (GDC-0449) in patients with locally advanced basal cell carcinoma (BCC) or metastatic BCC (mBCC) who are otherwise without satisfactory treatment options.
