Active clinical trials for "Neoplasms"

This study is to evaluate the effects (good and bad) of ALIMTA and Cisplatin or ALIMTA alone on you and your malignant pleural mesothelioma as well as make ALIMTA available to patients who qualify for treatment.

To determine the seroprevalence of Kaposi's sarcoma-associated herpesvirus (KSHV/HHV8) in blood donors from Texas. Also to examine the donors' demographic characteristics and to characterize the KSHV using polymerase chain reaction.

The purpose of this study is to identify affected individuals in families with prostate cancer and to use this information to identify genetic markers closely-linked to the disease gene.

This protocol concerns the approach to the localization, diagnosis of MEN1 and management of the tumor and the tissue samples in patients with Zollinger-Ellison syndrome. It details the diagnostic imaging tests to be used to localize the tumor, investigations for MEN1 the subsequent management of the tumor and tissue samples for research.

This study will determine what growth factors are involved in promoting and inhibiting mastocytosis-an abnormal increase of mast cells in one or more organ systems. Mast cells release chemicals that can cause itching, blisters, flushing, bone pain, and abdominal pain. Little is known about the disease and there is no cure. Steroids and antihistamines can help reduce some symptoms. Patients from birth to 80 years of age with increased mast cells in at least one organ system may be eligible for this 3-year study. Family members may also be enrolled for genetic testing. Patients will be evaluated yearly at the NIH Clinical Center with the following tests and procedures: Medical history and physical examination. Blood samples. Laboratory blood tests, as medically indicated. Bone marrow aspiration and biopsy - For the bone marrow aspiration and biopsy, the back hipbone is punctured with a sterile needle. Five milliliters (1 teaspoon) of marrow is withdrawn through a syringe and a 1/2-inch piece of tissue is extracted with a special needle. The blood and bone marrow samples will be used for clinical care and for research to determine if mastocytosis is due to mast cell growth factors or genetic changes. Patients who require further evaluation and tests will have recommendations made to their primary physician. Any patient who requires immediate treatment will be admitted to the hospital. Standard medical treatment may include antihistamines for itching; steroids for severe abdominal symptoms such as cramping, diarrhea, and evidence of increased mast cells determined by an upper GI study; and adrenaline for anaphylactic shock. Patients who do not respond to conventional treatment may be offered participation in an experimental therapy study. Participating family members will have a medical history and a blood sample drawn to look for genetic abnormalities.

Pancreatic cancer (PC) is recognized as one of the most challenging tumors to deal with and it is still characterized by a poor long-term prognosis. However, treatment of PC in high-volume centers with the support of a multidisciplinary approach has widely demonstrated improvement both in terms of short- and long-term outcomes. The recent worldwide spread of Covid-19 pandemic significantly affected the healthcare systems of most countries in the world, particularly in red areas such as Italy, with more than 100.000 cases in a two-month time lapse. This inevitably reflected in a reorganization of hospital activities, including the diagnostic and therapeutic pathways for PC treatment. With the aim of giving an objective and real representation of the impact of Covid-19 on PC treatment, the investigator here propose a multicenter Italian observational study comparing a 6-month period before and during the Covid-19 pandemic. Only high-volume centers will be involved in the study. A comparison between the general, clinical, endoscopic and surgical outcomes will be performed by means of a global and month-by-month analysis between the two study periods.

The aim of the study is to develop and implement robust analytical protocols for first-void urine sample preparation and antibody assays to monitor vaccine induced immunity against HPV (Human Papillomavirus).

Sarcomas are aggressive malignant tumors issued from mesenchymatous cells. Their curative treatment is mainly surgical, especially in soft tissue sarcomas, which are mostly localized in limbs. Surgical margins remain a major prognosis factor and are directly linked to recurrence risk. Curative surgery applies resection margins removing healthy tissue surrounding the tumor and is meticulously planned thanks to tight cooperation between expert surgeons and radiologist, based on pre-operative Magnetic resonance imaging(MRI). Resection planning optimizes chances to perform a safe carcinological resection procedure sparing these structures. Resection planning is based upon conservation (or sacrifice) of anatomic compartments limited by fascia and routine MRI might also be outdated in some cases to predict whether the fascia is involved in the tumor or not. Such uncertainties complexify the surgical procedure, lead to unnecessary healthy tissue sacrifices and increase functional impairments, which can be significant. A new MRI offering higher spatial resolution could allow tumoral satellites, previously undetected on conventional MRI, which might explain some of the observed recurrences. Ultra-high field MRI, considered as harmless and without pharmaceutical agent injection, could bring benefits to tumoral extension comprehension and should be considered as a breakthrough in medical oncology field. This is particularly true in soft tissue sarcoma pathology field, where the only curative treatment to date remains surgery. It will be propose in this project to determine the contribution of ultra-high field MRI in Soft tissue sarcomas management and to evaluate for the first time the potential superiority of 7 Tesla imaging over routine MRI through usual data comparison in 20 patients between 1,5Tesla and 7 Tesla MRI.
