What field and dose would you prescribe for a an extra-renal rhabdoid tumor of the pelvis?

Extrarenal, noncerebral rhabdoid tumors are relatively rare. However, the literature indicates an advantage for delivery of radiation therapy. Bourdeaut et al in 2008 reported on 26 patients with extrarenal, noncerebral rhabdoid tumors in whom the only surviving patient who had a proximal limb tumor received radiation and received the highest dose of radiation, 54 Gy, in total. Sultan et al reports a SEER data base study in which they examined 103 extrarenal, noncerebral rhabdoid tumors and find that the use of radiotherapy was associated with significantly improved survival. They quote older NWTS studies in which a dose of more than 25 Gy was associated with better outcome for this disease. Morgenstern et al reports in 2010 on a retrospect...
