Reproductive outcomes of 105 malignant ovarian germ cell tumor survivors: a multicenter study.

Malignant ovarian germ cell tumors usually occur in young women. Until the 1970s, before establishment of systemic chemotherapy, malignant ovarian germ cell tumors had a very poor prognosis. Recently,...

Long-term Outcomes of Globe-Preserving Surgery with Proton Beam Radiation for Adenoid Cystic Carcinoma of the Lacrimal Gland.

To describe outcomes of globe-preserving surgery combined with high dose proton beam radiation (PBR) in treating primary adenoid cystic carcinoma (ACC) of the lacrimal gland.

Biological effects and inter-individual variability in peripheral blood lymphocytes of healthy donors exposed to 60 MeV proton radiotherapeutic beam.

The aim of our study was to investigate the amount of initial DNA damage and cellular repair capacity of human peripheral blood lymphocytes exposed to the therapeutic proton beam and compare it to X-r...

Medical and Biotech [MESH] Definitions

An unusual and aggressive tumor of germ-cell origin that reproduces the extraembryonic structures of the early embryo. It is the most common malignant germ cell tumor found in children. It is characterized by a labyrinthine glandular pattern of flat epithelial cells and rounded papillary processes with a central capillary (Schiller-Duval body). The tumor is rarely bilateral. Before the use of combination chemotherapy, the tumor was almost invariably fatal. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1189)

An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.

The use of an external beam of PROTONS as radiotherapy.

Computed tomography modalities which use a cone or pyramid-shaped beam of radiation.

The use of pre-treatment imaging modalities to position the patient, delineate the target, and align the beam of radiation to achieve optimal accuracy and reduce radiation damage to surrounding non-target tissues.
