Estimated Radiation Dose to the Salivary Gland From Typical Radiotherapy Fields Used in the Treatment of Hodgkin Lymphoma.

		Dose to salivary gland (Gy)* (Range across the gland)
Technique	HL tumor dose delivered (Gy)	Parotid	Submandibular	Sublingual
Full mantle†	35	17.5 (1.75–30)	31.5 (30–35)	7 (3.5–17.5)
	20	10 (1–20)	18 (17–20)	4 (2–10)
Supraclavicular only	20	0.21 (0.12–0.30)	0.43 (0.20–0.56)	0.15 (0.14–0.16)
Neck only	20	10 (1–20)	18 (17–20)	4 (2–10)
Mediastinum only	20	0.12 (0.08–0.16)	0.25 (0.21–0.27)	0.14 (0.13–0.15)
Axilla only	20	0.06 (0.04–0.08)	0.10 (0.06–0.14)	0.07 (0.06–0.08)

Abbreviations: Gy: Gray; HL: Hodgkin lymphoma.

^*Radiation doses to major salivary glands were estimated using methods described by Stovall et al (23).

^†Upper field border at ear/jaw. Dose to the parotid and sublingual glands have high uncertainty due to their location on the edge of these fields.
