Suggested surveillance for rhabdoid tumors

Gene	Organ at risk	Type of mutation
		Germline truncating	Germline missense
		SMARCB1	Brain	MRI q 3 months to age 5 years	No screening, generally no/very low risk
	Abdomen	Consider WBMRI to age 5 years, undetermined frequency. Ultrasound q 3 months	No screening, generally no/very low riska
SMARCA4	Brain	No data available, risks likely very low
	Abdomen	No data available, risk likely low to very low
	Ovary	No data available, abdominal ultrasound q 6 months may be justified, role, if any, of MRI unknown. Preventive oophorectomy may be justified outside of the pediatric age range

Abbreviations: q, every; WBMRI, whole-body MRI.

^aSchwannomas may result from missense mutations and may justify MRI.
