ABSTRACT
Survival times for patients with leukemia generally have improved in recent decades, and this improvement has been attributed to an enhanced understanding of the genetics driving the cause of the disease and improved combinations of chemotherapy and targeted therapy. Durable control of systemic disease in blood and bone marrow has significantly improved survival, but extramedullary relapse can pose therapeutic challenges for which radiation therapy can have an important role. This report discusses the current role of radiation therapy for patients with leukemia, specifically the extramedullary manifestations of leukemia.

Photodynamic therapy (PDT) is a new treatment for head and neck cancer. The principle of the treatment is a photochemical reaction initiated by light activation of a photosensitizer, which causes the death of the exposed tissue. This article presents the modes of action of PDT and the techniques as well as the clinical procedure. A critical review of the literature is also presented, regarding treatment results of the different techniques and indications for treatments. The possibilities for PDT for head and neck cancer in Denmark are mentioned.
