Is radiotherapy with rectangular fields associated with fewer clinical failures than conformal fields in the high-risk prostate cancer subgroup : results from a randomized trial?
We found a significantly lower risk of early tumor progression for patients treated with rectangular fields. Treatment failure can probably in part be prevented by irradiation of areas suspected of subclinical disease in high-risk prostate cancer.
The results indicate that, in the anaesthetized rabbit with denervated arterial and cardiopulmonary baroreceptors, endogenous angiotensin is tonically released within the rostral ventrolateral medulla and facilitates the synaptic excitation of sympatho-excitatory neurons reflexly evoked by stimulation of afferent fibres in the sciatic nerve.
