Patients have a type of lymph gland cancer called HD, NHL or lymphoepithelioma (these 3 diseases will be referred to as "Lymphoma"). The lymphoma has come back or has not gone away after treatment. This is a research study using special immune system cells called TGFb-resistant LMP-specific cytotoxic T lymphocytes (DNR-CTL), a new experimental therapy. Some patients with Lymphoma show signs of infection with the Epstein Barr virus (EBV) before or at the time of their Lymphoma diagnosis. EBV is found in the cancer cells of up to 1/2 the patients with Lymphoma, suggesting it may play a role in causing Lymphoma. The cancer cells infected by EBV are able to hide from the body's immune system and escape being killed by releasing a substance called Transforming Growth Factor-beta (TGFb). The investigators want to see if special white blood cells (called T cells) that have been given a gene that they hope will let them survive against TGFb and that have been trained to kill EBV infected cells can also survive in the blood and kill the tumor. Investigators have used this sort of therapy with specially trained T cells to treat a different type of cancer that occurs after bone marrow and solid organ transplant called post transplant lymphoma. In this type of cancer they were able to successfully prevent and treat post transplant lymphoma. However when they used a similar approach in HD some patients had a partial response to this therapy, but no patients had a complete response. In a follow-up study they tried to find out if they could improve this treatment by growing T cells that recognize 2 of the proteins expressed on Lymphoma cells called LMP-1 and LMP2a. These special T cells were called LMP-specific cytotoxic T-lymphocytes (CTLs). Although some patients had tumor responses, CTL therapy alone did not cure those who had a lot of disease. Investigators think that a reason for this is that the tumor cells are releasing TGFb. For this reason, they want to find out if they can make the CTL resistant to TGFb by putting in a new gene called TGFb resistance gene. Investigators hope that this will improve this treatment for relapsed lymphoma. These TGFb-resistant LMP-specific CTLs are an investigational product not approved by FDA. The purpose of this study is to find the largest safe dose of TGFb resistant LMP-specific CTLs, to learn what the side effects are and to see whether this therapy might help patients with Lymphoma.
This study will evaluate the efficacy of Problem Adaptation Therapy (PATH) vs. Supportive Therapy for Cognitively Impaired (ST-CI) older adults in reducing depression and disability in treating depressed, cognitively impaired older adults.
The number of patients requiring joint replacement is increasing due to its success in restoring function and pain relief, and the growing population of the elderly. One of the most serious complications of arthroplasty is joint prosthesis infection. Due to the absence of prospective, randomized, controlled studies, there is no consensus concerning diagnosis and treatment of prosthetic joint infections. The main objective of this trial is to evaluate the clinical efficacy of rifampin combination therapy versus monotherapy using cloxacillin or vancomycin in early staphylococcal infections after total hip and knee arthroplasty.
Intravitreal triamcinolone has been effective for central macular thickness reduction and concomitant visual acuity improvement in patients with diabetic macular edema (DME). VEGF is a very effective inducer of permeability, being 50.000 times more potent than histamine, and may exert its effect on retinal vascular permeability by altering tight-junctions proteins, such as occluding and VE-cadherin. Based on these principles, there is a rationale for anti-VEGF agents treatment of increased retinal capillary permeability conditions, such as diabetic macular edema. Therefore, we conducted a randomized, prospective study to compare the efficacy and safety of intravitreal triamcinolone acetonide and intravitreal bevacizumab injection for refractory diffuse DME.
The investigators designed the randomized prospective trial of comparing open and laparoscopic resection in locally advanced rectal cancer after preoperative chemoradiation in order to determine the oncologic and functional efficacy of laparoscopic rectal resection.
Colorectal cancer is a type of cancer that begins in the large intestine (colon) or the rectum (end of the colon). Several drugs are often given in combination to treat colorectal cancer. One of the most active treatment combinations is known as FOLFOX, which is a combination of 5-fluorouracil (5-FU), leucovorin, and oxaliplatin. Oxaliplatin is a type of platinum drug and was approved by the FDA in 2004. While generally well-tolerated, oxaliplatin may cause toxicity to the nerves, such as sensory loss or cold sensitivity. Picoplatin is a new type of platinum drug that has shown activity with 5-FU in pre-clinical studies and has undergone extensive Phase 1 and Phase 2 testing in a variety of cancers. No significant nerve toxicity has been seen in previous studies of picoplatin. This study will review the safety and effectiveness of FOLPI, which is the combination of 5-FU and leucovorin with picoplatin in participants with colorectal cancer.
The present study was designed to evaluate the treatment of adenoviral corneal opacities with PTK and mitomycin C.
The purpose of this study is to determine if the use of BNP/NT-proBNP levels in the detection of early left ventricular dysfunction and damage may improve the timing of cardiac surgery and therefore the long-term management of asymptomatic patients with severe mitral regurgitation.
chemotherapy- and radiotherapy-induced oral mucositis represents a therapeutic challenge frequently encountered in cancer patients.This side effect causes significant morbidity and may delay or interrupt the treatment plan, as well reduce therapeutic index. cyclo-oxygenase 2 (COX-2) is an inducible enzyme primarily expressed in inflamed tissues and tumor. COX-2 inhibitors have shown promise as radio- and chemosensitizer and reduce radio-induced toxicities. we have conducted a phase III, randomized double blind clinical trial to evaluate the toxicity and efficacy of celecoxib, a selective COX-2 inhibitor, administered concurrently with chemotherapy, and radiation for locally advanced head and neck cancer.
The purpose of this study is to assess the short and long-term outcomes after CyberKnife stereotactic radiosurgery for early stage non-small cell lung cancer (NSCLC) in patients who are medically inoperable.
