Active clinical trials for "Lymphoma"

RATIONALE: Diagnostic procedures, such as anal swab collection, digital rectal examination, and anal endoscopy and biopsy, may help find and diagnose anal and genital human papillomavirus infection and squamous intraepithelial lesions and help doctors plan better treatment. PURPOSE: This clinical trial is studying ways to detect anal and genital human papillomavirus infection and squamous intraepithelial lesions in HIV-positive patients enrolled in an AIDS cancer clinical trial.

.This study is trying to address change of chemotherapy dosage according to individual patient response to initial cycles of chemotherapy in order to reduce cumulative dose of chemotherapy.The study includes patients with early unfavorable and advanced hodgkin lymphoma. Patients with low risk were started with standard beacopp and only high risk patients were started with escalated beacopp.Following 2 cycles of therapy the patients were reassessed.Based on scintigraphy results decision was made regarding further therapylative chemotherapy for early responders and maximize dose intensity for late responders.

RATIONALE: Questionnaires that measure coping may improve the ability to plan supportive care for patients undergoing donor bone marrow transplant. PURPOSE: This clinical trial is studying coping in patients who are undergoing a donor bone marrow transplant.

This is a prospective, observational, longitudinal, multicenter study of patients with newly diagnosed follicular Non Hodgkin's Lymphoma (NHL) designed to delineate differences in clinical outcome by comparing the effectiveness and safety of common treatment regimens.

RATIONALE: Determination of genetic markers for leukemia or non-Hodgkin's lymphoma that is secondary to Hodgkin's disease and childhood brain tumors may help doctors to identify patients who are at risk for these cancers. PURPOSE: Clinical trial to determine the presence of certain genes in patients who are receiving treatment for Hodgkin's disease or childhood brain tumors.

Although the cause(s) of clinical drug resistance in non-Hodgkin's lymphomas (NHL) are unknown, in vitro studies suggest that abnormalities of the cell cycle and mechanisms of apoptosis may play an important role. Clinical studies have now shown that p53, bcl-2 and tumor proliferation all have significant effects on clinical drug resistance. To further investigate the role of genes that control the cell cycle and apoptosis, we wish to correlate the expression of multiple molecular targets [including but not restricted to bcl-2, BAX, bcl-6, MIB-1, p53, p21, p27, p16, cyclin D(1), cyclin A, cyclin E, mdm-2, cpp 32, mcl-1, EBER-1, ALK, and a panel of B, T and other cell lineage markers], involving these pathways, with clinical outcome following treatment with combination chemotherapy. All clinical data and tissue samples for this study will come from patients who have been previously enrolled on two protocols for the initial treatment of aggressive lymphomas. No new patients will be enrolled for this study.

Non-Hodgkin's lymphoma has been studied in the Pediatric Branch for at least 20 years, during which time a number of different treatment protocols have been used. Approximately 110 patients have apparently been cured of their lymphoma. The present protocol has no therapeutic component, but is designed to document the late effects that may have been encountered by our patients, either as a consequence of the disease or its treatment. In essence, patients who consent to participate will be asked a series of questions pertaining to the quality of their life and possible medical problems that they may be encountering. In addition, they will receive a complete physical examination and undergo non-invasive investigations designed to identify the presence of unsuspected late effects. Investigators in the Eye Clinic, Dental Clinic, Audiology, Cardiology and Endocrinology departments will participate in the protocol. As a part of the study, blood samples will be obtained to investigate the possibility that predisposing genetic factors may be identifiable in the patients normal cells (e.g., p53 mutations, evidence of DNA instability). If such abnormalities are detected, blood samples from family members will also be examined to determine whether the defect was inherited.

The purpose of the study is to investigate the proportion of the cell-of-origin (COO) subtypes in relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) treated with BTK inhibitor or lenalidomide and its biosimilars.

This prospective, open-label, multicenter, observational study will investigate the effectiveness and safety of MabThera SC (rituximab, subcutaneous) induction therapy in patients with non-Hodgkin's lymphoma, following a first initial treatment of MabThera IV (rituximab, intraveneous). Induction treatment period in the study is estimated to be 8 months.

The purpose of this study is to determine whether 18F-Al labeled RGD is safety and effective for cancer diagnosis and therapy response.
