Active clinical trials for "Neoplasms"

Primary Objectives: To enroll and obtain, through questionnaires, risk factor information on all study participants to develop detailed demographic, epidemiologic and behavioral profiles. To assess the influence of relevant epidemiologic covariates such as age, gender, smoking and family history of cancer on the panel of susceptibility biomarkers. To evaluate the role of genomic instability in development of lymphomas.

The intent of the proposed study is to describe the prevalence of the most common recurring mutations in BRCA1 and BRCA2, blmAsh , and the A636P MSH2 mutation among Ashkenazi Jewish individuals with a variety of cancer diagnoses. If a substantial proportion of these samples contain such mutations, future patients presenting with these diseases may wish to undergo genetic counseling and, if appropriate, formal genetic testing. The benefit from such a process would pertain mainly to the families of these individuals.

Compare the clinical characteristics and post-surgical outcomes (overall survival)of pancreatic cancer patients of Ashkenazi descent with or without germline founder mutations in BRCA1 or BRCA2 . Compare the clinical characteristics and outcomes (time to progression) of breast cancer patients of Ashkenazi descent with or without germline founder mutations in BRCA1 or BRCA2 receiving paclitaxel chemotherapy for metastatic disease.

Subjects with newly diagnosed brain tumors who undergo surgical resection and whose pathology in the operating room shows a high grade glioma will be eligible. During a screening visit, the study will be discussed, inform consent discussed and signed, a medical history will be taken and a physical examination and laboratory tests will be performed. If these tests are all within acceptable ranges, the subject will be considered for inclusion on this treatment protocol. If the results of any tests are extremely different from normal expected values, she/he may not be able to participate. Prior to surgery, the subject will have a contrast enhanced MRI and MRS. The neurosurgeon will attempt to remove the majority of the tumor in the operating room and will send a portion of the specimen removed to the pathologist immediately. This is called a "frozen section". If the pathologist believes that the tumor is a high-grade malignant brain tumor, then the surgeon will place up to 8 dime-sized chemotherapy wafers in the tumor cavity of the brain. The remainder of the tumor specimen will be given to the pathologist to review more closely in the laboratory. If the frozen section does not show that the tumor is a high-grade malignant brain tumor, the subject will not receive the Gliadel wafers and will be removed from the study. The surgeon will then discuss with the subject the appropriate treatment options for the disease he or she has. During recovery in the hospital, another contrast enhanced MRI will be performed within the first 72 hours after surgery. This is a standard of care for patients who are not involved on this protocol as well. The subject will have another contrast enhanced MRI and MRS performed at the 21st Day after his or her surgery. After Day 21, He or she may begin other forms of treatment. The last contrast enhanced MRI and MRS assessment will be performed 12 weeks after the surgery and the implantation of the Gliadel wafers. Further MRI and MRS may be performed subsequently at the discretion of the doctor. Throughout the course of treatment, clinical data will be collected.

Trends in Incidence and Survivals for Ovarian Germ Cell Tumors: A 27-Year Population-Based Study

The objective of this study is to determine whether women who are already receiving treatment for their fibroids (ie. UAE) demonstrate improvement in urinary symptoms and sexual dysfunction as well.

The purpose of this study is to determine if you can use an assay on tumor samples to see different patterns in response to the same chemotherapy treatment.

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.

This pilot research trial studies molecular signatures of the return of cancer after a period of improvement (relapse) in tissue samples from patients with small cell lung cancer who are receiving or planning to receive cisplatin and etoposide. Studying samples of tissue from patients with small cell lung cancer in the laboratory may help doctors learn more about the changes that occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer relapse.

The primary objective is to develop a rapid in vitro screening assay for detection of pancreatic cancer biomarkers in blood of patients with pancreatic cancer.
