Vaccine strategies in non-Hodgkin's lymphomas

Gene therapy approaches for multiple myeloma

Several different myeloma gene therapy approaches are currently being explored, seeking to impact on the disease process in diverse ways. Therapeutic benefit may result from destroying the myeloma cells directly, provoking an antimyeloma cell immune response, interfering with the paracrine growth signaling pathways between osteoclasts and myeloma cells, or genetically manipulating hematopoietic progenitors or mature T cells in a stem cell transplantation setting. Encouraging progress in each of these areas is being fueled by the development of improved viral and nonviral gene transfer vectors.

Cardiac Neoplasms

Surgical resection is usually the only form of curative therapy available for primary cardiac neoplasms. Benign tumors can often be completely removed with few complications and a low mortality rate, but complete resection is possible for fewer than half of primary malignant tumors. Radiation therapy plays an adjunct and palliative role in treatment. The outcome of chemotherapy, the dominant treatment method, is poor. Sarcomas are inherently chemoresistant and show a response rate of less than 50%. Lymphomas present late and respond poorly. Cardiectomy and cardiac transplantation may cure unresectable benign cardiac tumors or, rarely, malignant ones.
