Table 1

Radiation dose and volume by tumor stage or clinical presentation.

Stage III-IV favorable histology	(1) Whole abdomen irradiation (WAI) 10.8 Gy in six 180 cGy fractions. Supplemental doses of 1080 cGy are given to patients with residual tumor.
	(2) Metastatic sites: liver irradiation 19.8 Gy, lesser volumes may receive 540 to 1080 cGy, 3060 cGy doses should not be given to more than 75% of the liver volume; whole lung irradiation 12 Gy followed by an additional 750 cGy; lymph node irradiation 19.8 Gy followed by a local boost of 5.4–10.8 Gy; whole brain irradiation 30.6 Gy; bone irradiation 30.6 Gy.
Stage II–IV anaplasia	(1) Patients will receive supplemental “boost” irradiation 19.8 Gy. Whole abdomen irradiation (WAI) 19.8 Gy followed by a flank boost 9 Gy are given to patients with stage III-IV anaplasia.
	(2) Metastatic sites: same as stage IV favorable histology.
Stage II–IV clear cell sarcoma	(1) Supplemental irradiation 10.8 Gy are given to patients with stage II clear cell sarcoma. Whole abdomen irradiation (WAI) 10.8 Gy followed by a local boost. Metastatic sites are given to patients with stage III clear cell sarcoma.
	(2) Metastatic sites: same as stage IV favorable histology.
Stage I–IV rhabdoid tumor	(1) Whole abdomen irradiation (WAI) 19.8 Gy followed by a local boost. Patients 12 months or younger will have their total dose reduced to 10.8 Gy.
	(2) Metastatic sites: same as stage IV favorable histology.
