Endoscopic scoring of late gastrointestinal mucosal damage after adjuvant radiochemotherapy

Table 1 Endoscopy score system based on the system proposed by Wachter et al[7]

	Congested mucosa	Telengiectasia	Ulceration	Stricture	Necrosis
Score 0	Grade 1	None	None	None	None
Score 1	Grade 2	Grade 1	None	None	None
Score 2	Grade 3	Grade 2	None	None	None
Score 3	Any	Grade 3	Grade 1	None	None
Score 4	Any	Any	Grade 2	Grade 1	None
Score 5	Any	Any	Grade > 3	Grade > 2	Any

Table 2 RTOG-EORTC late radiation morbidity scoring system (part for small/large intestine)

	Grade 0	Grade 1	Grade 2	Grade 3	Grade 4
Small/ large intestine	None	Mild diarrhea, mild ramping, bowel movement 5 times daily, slight rectal discharge or bleeding	Moderate diarrhea and colic, bowel movement > 5 times dialy, excessive rectal mucusor intermittent bleeding	Obstruction or bleeding requiring surgery	Necrosis, perforation, fistula
