Mucositis grading scales OMAS

The Radiation Therapy Oncology Group (RTOG) has developed the Acute Radiation Morbidity Scoring Criteria for the evaluation of Radiotherapy treatments.

The RTOG grading is reliant on a clinician's ability to judge the anatomical changes associated with oral mucositis (size and characteristics of ulceration).

RTOG Scoring Criteria

0 (none)

No change over baseline

Irritation, may experience slight pain, not requiring analgesic

Patchy mucositis that may produce inflammatory serosanguinitis discharge; may experience moderate pain requiring analgesia

III (severe)

Confluent, fibrinous mucositis, may include severe pain requiring narcotic

IV (life-threatening)
