[A comparative consideration of para-aortic fields within the framework of the German Hodgkin's Disease Study]

In 33 patients of the multicenter German Hodgkin's Lymphoma Study Group the field borders of the paraaortic field were compared computer-assisted. It was seen that fields are chosen often too small or too large, though precise description of the fields is given in the protocol. In these patients the para-aortics were irradiated exclusively as extended field region. In addition to the above observation the clipping of the spleen pedicle provides the optimal help for correct positioning of this field. Overall a very low frequency of lymphatic clipping is observed, though clinical needs are obvious.
