By understanding this pathway, scientists can develop strategies to make tumours more vulnerable to certain drugs, leading to improved treatment outcomes for patients with cancer.
New research by Rockefeller University shows that bortezomib can kill multiple myeloma cells in a way that elicits an immune response, potentially enhancing patients' immunity to tumors. The treatment works by exposing heat shock proteins on dying cells, which then activate dendritic cells to present antigens to memory and killer T cells.
A phase III clinical trial found that the first antisense drug, oblimersen, improved response rates in CLL patients who remained sensitive to chemotherapy drug fludarabine. The study showed a four-fold increase in 'CR/nPR' in these patients compared to those no longer responding to fludarabine.
A study published in the Journal of the National Cancer Institute found that women with breast cancer who received growth factors during chemotherapy had a higher risk of developing leukemia or myelodysplastic syndrome. The absolute risk is small, but it should be considered when making treatment decisions.
A breast cancer treatment based on MIT research is documented in a new book, including promising results from the latest clinical trials of the therapy. The technique uses microwaves to heat-and-kill-cells containing high amounts of water and ions, showing minimal side effects.
