Immunotherapy
Toward an “ultra-personalized” therapy for melanoma
With new immunotherapy treatments for melanoma, recovery rates have risen dramatically – in some cases to around 50%. But they could be much higher. A new study led by researchers at the Weizmann Institute of Science showed, in lab dishes and animal studies, that a highly personalized approach could help the immune cells improve their ability to recognize the cancer and kill it.
Myelodysplastic syndrome
Genetic testing helps predict disease recurrence
A DNA-based analysis of blood cells soon after a stem cell transplant can predict likelihood of disease recurrence in patients with myelodysplastic syndrome (MDS), a group of cancerous disorders characterized by dysfunctional blood cells. Such a practice could help doctors identify patients at high risk of disease recurrence early after a transplant and help guide treatment decisions.
