	> 10 cm to ≤ 15 cm	1.172	3
	> 15 cm	1.742	5
Grading	High-grade	0.141	0
Grading	Low-grade	− 0.917	− 3
Radiotherapy	No	0.050	0
Radiotherapy	Neo-adjuvant	1.297	3
Hemoglobin	0 ≤ 10.4	2.779	8
	10.4–12.2	0.518	1
	12.2–13.6	− 0.656	− 2
	13.6–14.8	− 1.909	− 5
	≥ 14.8	− 2.988	− 8
Presence of coronary heart disease	Ja	2.028	8
Presence of coronary heart disease	Nein	− 0469	− 2

The created score was named “TRANSAR” as acronym for “Tran” (Transfusion) and “Sar” (Sarcoma)
