Randomized Controlled Trial Comparative Study
Prospective randomized study of intensity-modulated radiotherapy on salivary gland function in early-stage nasopharyngeal carcinoma patients.
This randomized trial compared the rates of delayed xerostomia between two-dimensional radiation therapy (2DRT) and intensity-modulated radiation therapy (IMRT) in the treatment of early-stage nasopharyngeal carcinoma (NPC). ⋯ IMRT is superior to 2DRT in preserving parotid function and results in less severe delayed xerostomia in the treatment of early-stage NPC. Incomplete improvement in patient's subjective xerostomia with parotid-sparing IMRT reflects the need to enhance protection of other salivary glands.

To evaluate the role of donor lymphocyte infusion (DLI) in the treatment of relapsed acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (HSCT). ⋯ Although further evidence for a graft-versus-leukemia effect by DLI is provided, our results confirm, that the clinical benefit is limited to a minority of patients. Strategies to reduce tumor burden before DLI, as well as alternative treatment options should be investigated in adults with relapsed AML after HSCT.
