Filter by:The purpose of this study is to determine the safety and maximum tolerated dose of Photocyanine injection in photodynamic therapy of malignant tumor (especially skin cancer and esophageal cancer). Projected accrual: A total of 18-24 patients will be accrued for this study.
Gastroentero-pancreatic neuroendocrine tumours (GEP-NETs) are regarded as a fairly rare disease. They are derived from the neuroendocrine system of the gastrointestinal tract and the pancreas and share common clinical features. So far, there is still uncertainty about the cell biology and mechanistic regulation of these tumours. Therefore targeted treatment is limited and management challenging. Treatment options include surgery, medical and ablative therapy, and more recently peptide-receptor radionuclide therapy. In order to better understand the characteristics of GEP-NETs and to evaluate treatment strategies, the SwissNET registry aims at the collection of data from patients presenting with a GEP-NET in Switzerland. Data will be entered prospectively and anonymized in a specifically designed database after the patient has given informed consent. All hospitals and general practitioners are invited to report on patients with a GEP-NET diagnosis and to participate to the registry. Data will be evaluated within regular time frames, focussing on types of GEP-NETs, treatment modalities and patient outcomes (e.g. mortality, hospitalisation rate), thereby contributing to the better understanding of these tumours.
The principal research objective of this additional research protocol is to support the collection, storage and use of tumour and surrogate (peripheral blood mononuclear cells - PBMNCs). The objective of this study is to perform assays to study pharmacodynamic (PD) markers that confirm target modulation.
Background: - Endocrine neoplasms (tumors) are among the fastest growing tumors in incidence in the United States. Furthermore, it is often difficult to distinguish between benign or malignant tumors in cancers of the thyroid, parathyroid, adrenal gland, and pancreas. More research is needed to improve detection and treatment options for patients who develop these kinds of cancer. - Researchers are interested in studying the molecular changes that are involved in endocrine cancer development and growth. To collect a sample of tumor specimens and healthy tissue for further study, researchers are specifically looking for samples from patients who are scheduled for surgery or biopsy on endocrine tumors. Objectives: - To collect samples of precancerous, cancerous, and healthy tissue from individuals who are scheduled for surgery or biopsy of endocrine system tumors. Eligibility: - Individuals who have a tumor in or around their thyroid, parathyroid, adrenal gland, pancreas, or any neuroendocrine tissue, and are scheduled for surgery at the National Institutes of Health Clinical Center. Design: - Participants in this study will provide blood and urine samples prior to surgery. - During the surgery or biopsy, pieces of the tumor or precancerous growth and pieces of normal tissue near to the tumor will be removed for ongoing and future research. The rest of the tumor or growth will be sent for analysis. - After surgery, participants will receive routine care until discharge, and doctors will discuss possible treatment options. If there is an appropriate NIH protocol, participants may choose to be treated at the NIH. - After discharge, participants will return to the clinic for a routine postoperative check about 6 weeks following the operation, and then may be followed yearly at the Clinical Center or by phone.
This study collects information on the side effects of proton therapy and detailed information on the proton therapy treatment plan itself. This may help researchers develop methods to predict the risk of side effects for future patients and learn the long-term benefit of proton therapy.
Paediatric patients affected by haematological malignancies and eligible to undergo HSCT from an unrelated volunteer will be stratified according to the degree of compatibility with their donor, the source of haematopoietic stem cells employed (BM vs. PB) and the disease phase (good vs. poor prognosis). In particular, on the basis of compatibility with their donor, patients will be allocated to 2 different arms: those transplanted from an unrelated donor either perfectly matched or with a single allelic disparity at one of the HLA loci (i.e. A, B, C, and DrB1) vs. those transplanted from an unrelated donor either with 2 allelic disparities or with an antigenic disparity at the HLA loci (i.e. A, B, C, and DrB1). Patients enrolled in the study will be randomized to receive ATG (Fresenius) at a dosage of either 30 mg/Kg (10 mg/Kg on days -4, -3 and -2) or 15 mg/Kg (5 mg/Kg on days -4, -3 and -2). Good prognosis patients are defined as follows: ALL in 1st CR; ALL in 2nd CR belonging to S2 group; AML in 1st CR, AML in 2nd CR and relapsed more than 6 months after stopping therapy; NHL in 2nd CR; Ph+ CML in 1st CP; refractory cytopenia. Poor prognosis patients are defined as follows: ALL in 2nd CR belonging to the S3-S4 group; ALL in ≥ 3rd CR; AML in 2nd CR and relapsed less than 6 months after stop therapy; secondary AML; NHL in 3rd CR; Ph+ CML in 2nd CP, as well as in AP; RAEB, RAEB-t, JMML.
The purpose of this study is to evaluate the incidence of complications with the isolated Roux-en-Y reconstruction after pancreaticoduodenectomy in pancreatic tumor and periampullary tumor patients. A prospective randomized controlled trial was conducted to compare the incidence of complications with isolated Roux-en-Y reconstruction with those of Billroth-II-type reconstruction after pancreaticoduodenectomy.
The purpose of this study is to offer an alternative method to women who wish to preserve the possibility of fertility, as well as to learn more about the ability of human eggs to survive and function after long term storage in frozen ovaries (ovarian tissue cryopreservation). The study will seek to preserve ovarian tissue and reproductive potential for patients whose medical or surgical treatment may harm ovaries or remove ovarian tissue.
This is multicenter, open-label, randomized, active-controled, phase IV study of local direct intra-tumor injection of rAd-p53 monotherapy, with concurrent chemotherapy , or combination with surgery for treatment of advanced oral and maxillofacial malignant tumors.
RATIONALE: Collecting and storing samples of tissue or blood from patients with cancer for study in the laboratory may help the study of cancer in the future PURPOSE: This research study is collecting and storing blood and tissue samples from patients with suspected solid tumors.
