Active clinical trials for "Lymphoma"

Radiation therapy, total skin electron therapy (TSET), achieves a high response rate and is an effective treatment for cutaneous T-cell lymphoma affecting the superficial region 1. One the most widely used TSET techniques consists of six dual fields initially developed at Stanford University 2. Dosimetrically, TSET at energies of about 3-7 MeV at the surface of a standing patient may result in significant dose variations due to variable skin distance, self shielding, irradiated fields overlapping and patient motion. Deviations occur from the prescription dose up to 40% and the surface dose inhomogeneity as much as 90% in body areas such as the perineum and eyelid, are revealed in the literature. To improve this condition, a selection of patients with advanced skin disease and regional extension could be cured by a combination of TSEB and photon beam irradiation. Helical tomotherapy (HT) has advantages in irradiating extended volumes with treatment length of up to 160 cm, continuously in a helical pattern without the need for field junction. Total marrow irradiation (TMI) via HT with low toxicities for bone marrow transplantation of Asia multiple myeloma patients could be feasible . A study of HT for total scalp irradiation has also shown that the employment of directional and complete blocking on the inner structures can effectively force the tangential delivery of the majority of beamlets to the PTV, which can limit the treatment depth. Using HT, an image-guided intensity-modulated radiotherapy, to replace conventional TSI technique to increase dose delivery and decrease toxicities could be a workable and feasible. Here, we applied TSI via HT (HITS) for a woman with T cell lymphoma failure by chemotherapy, topic UV irradiation and local radiotherapy (RT) in MMH to overcome the surface dose inhomogeneity by conventional RT. Additionally, we will compare the advantages and disadvantages between the plan of HT and conventional RT for TSI.

DLBCL has the highest frequency out of all lymphoid malignancies. With the recent development of antitumor agents targeting intracellular/extracellular cell signaling pathways, patients have access to various treatment options after relapse. Therefore, for the purpose of developing effective treatment strategies, large-scale genomic data accumulation is necessary to understand the mechanism of relapse and refractory state of DLBCL.

To determine whether peripheral blood flow cytometry can reduce or replace invasive bone marrow examinations in patients with slow growing lymphomas.

MiRNAs are small (~19-25 nucleotides) non-coding RNA molecules that bind to mRNA in a sequence-specific manner. MiRNAs regulate gene expression at the post-transcriptional level. MiRNAs regulate critical cell processes such as metabolism, apoptosis, development, cell cycle, hematopoietic differentiation and have been implicated in the development and progression of several types of cancers, including hematological malignancies. Over-expression, amplification and/or deletion of miRNAs and miRNA-mediated modification of epigenetic silencing can all lead to oncogenic pathways. Hematologic cancers, which are caused by the malignant transformation of bone marrow cells and the lymphatic system, are usually divided into three major clusters: leukemia, lymphoma, and multiple myeloma. To date, some of the hematological malignancies are very aggressive that early diagnosis is essential for improving prognosis and increasing survival rates. However, current diagnostic methods have various limitations, such as insufficient sensitivity, specificity, it is also time-consuming, costly, and requires a high level of expertise, which limits its application in clinical contexts. Thus, development of new biomarkers for the early detection and relapse of hematological malignancies is desirable. Some of the innate properties of miRNAs make them highly attractive as potential biomarkers. MiRNAs can be readily detected in small volume samples using specific and sensitive quantitative real-time PCR; they have been isolated from most body fluids, including serum, plasma, urine, saliva, tears and semen and are known to circulate in a highly stable, cell-free form. They are highly conserved between species, allowing the use of animal models of disease for pre-clinical studies. Furthermore, tumor cells have been shown to release miRNAs into the circulation and profiles of miRNAs are altered in the plasma and/or serum of patients with cancer. A growing number of publications confirm that miRNAs can be a useful biomarker for hematological malignancies diagnosis and progression.

The primary purpose is to investigate the relationship between the dose of chemotherapeutic agents per kilogram of lean body mass (LBM) and the development of side effects induced by chemotherapy in patients with lymphoma. Secondarily, the maximum tolerable dose of chemotherapeutics (MTD), patients' quality of life (QOL), nutritional status and physical activity during the course of treatment are estimated.

The aim of this study is to identify the incidence of hepatitis B virus reactivation rate in Diffuse Large B Cell or high grade Follicular lymphoma patients with prior resolved hepatitis B undergoing RCHOP immuno-chemotherapy.

Early interim-PET after two courses of chemotherapy is a powerful outcome predictor in advanced-stage Hodgkin Lymphoma (HL) patients treated with adriamycin (doxorubicin), bleomycin, vinblastine and dacarbazine (ABVD). Two-year Progression Free Survival of PET-2 positive patients is only 12%, but the optimal treatment for this patient subset is still unknown. From January 2006 GITIL (Gruppo Italiano Terapie Innovative nei Linfomi) suggested an early intensification of chemotherapy with BEACOPP [Bleomycin, Etoposide, Adriamycin (doxorubicin), Cyclophosphamide, Oncovin (vincristine), Procarbazine, and Prednisone](4 escalated + 4 baseline cycles) for all the HL patients with a positive PET-2 after 2 ABVD courses. The investigators retrospectively recorded and analyzed these data in order to evaluate if this strategy could be of benefit for this subset of patients.

This retrospective study was proposed by the investigators to analyze treatment status and outcome in patients with early relapsed follicular lymphoma. In patients with follicular lymphoma who experienced disease progression within 24 months after initiation of treatment, the second-line therapy, stem cell transplantation, tumor response, progression free survival, and overall survival will be analyzed.

The Drug Use Examination (DUE) is planned and designed for the safety evaluation of new indications after the approval of a new drug in Korea. This DUE is a non-interventional, observational and post-marketing surveillance, which will be conducted by collecting the safety information of REVLIMID® for new indications in routine clinical practice in Korea. Six-Hundred (600) adult patients, who start with REVLIMID® treatment based on the approved local package insert (PI) of REVLIMID® during routine clinical practice in Korea and have indications noted below.
