Dendritic cell vaccine treatment for indolent B cell non-hodgkin lymphoma: clinical trial in progress

چکیده
Methods Autologous mature dendritic cells (mDC) were manufactured from leukapheresed cells of NHL patients. For patients with tumor lymph nodes deemed amenable to cryoablation by interventional radiologist (arm A), they received cryoablation of a node and injection of mDC into the cryoablated node followed by another 1 to 7 intratumoral mDC injections. Remaining patients had a tumor excised to generate tumor lysate ex vivo. mDC were pulsed with tumor lysate during DC maturation (arm B; DC-TL). The DC-TL vaccines were injected intradermally for 4 to 8 doses. Patients are monitored for one year after vaccines for adverse events and systemic tumor response. Correlative studies include cellular immune phenotype of peripheral blood and T cell intracellular cytokine productions. Planned accrual is 10 patients per arm (total = 20).

Unusual Presentation of T-cell non-Hodgkin Lymphoma with Multiple Skin Nodules
Non-Hodgkin lymphoma is very uncommon in infancy and skin as the primary site of involvement in Non-Hodgkin lymphoma is rarely encountered. We describe a 10-month-old infant with T-cell Non-Hodgkin lymphoma who presented with multiple skin nodules as the predominant feature of her disease. The clinical manifestations, treatment strategy and disease outcome are reviewed. Key words: Non-Hodgk...
متن کاملDevelopment of DOTA-Rituximab kit formulation to be labeled with 90Y for radioimmunotherapy of B-cell Non-Hodgkin Lymphoma
NHL is the most common hematologic cancer in adults. Rituximab is the FDA approved treatment of relapsed or refractory low grade B-cell Non-Hodgkin Lymphoma (NHL). But patients eventually become resistant to rituximab. Since lymphocytes and lymphoma cells are highly radiosensitive, low grade NHL that has relapsed or refractory to standard therapy is treated by RIT in which a beta-emitting radio...

Lymphomas are solid tumors of immune system and Non-Hodgkin Lymphomas (NHL) is the most prevalent lymphomas; with wide ranges of histological and clinical features, it is so difficult to identify them. Herein, various bioinformatics tools (such as gene differential expressions, epigenetics and protein analysis) employed to find new treatment approach for NHL based on gene expression variation b...
