What is a CTC grade?
The Common Terminology Criteria for Adverse Events (CTCAE), formerly called the Common Toxicity Criteria (CTC or NCI-CTC), are a set of criteria for the standardized classification of adverse effects of drugs used in cancer therapy.
Which NCI CTCAE grade indicates the most mild adverse event?
Grade refers to the severity of the AE. The CTCAE displays Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated.
What is a toxicity grade?
Toxicity grading scales provide consistency in reporting, and provide a framework for assessment and documentation of adverse effects. Objective assessment of the impact of treatment may inform the need for adjustments to the treatment plan.
What is CTCAE v4?
Common Terminology Criteria for. Adverse Events (CTCAE) Version 4.0.
How are adverse events graded in clinical trials?
The CTCAE includes 837 AE terms for 26 system/organ classes, with most AEs classified into five severity grades (1 = mild, 2 = moderate, 3 = severe, 4 = life threatening, and 5 = death). Adverse events are typically assessed and reported immediately after each cycle of treatment.
What is the purpose of CTCAE?
CTCAE is an internationally accepted standard for defining and categorizing adverse events. It allows us to talk to our patients in a more useful way, and it also allows us to speak the same language as cutting-edge oncology researchers around the world.
Are all Grade 4 adverse events serious?
A severe AE (Grade 3 or 4) does not necessarily need to be considered serious. For example, a white blood cell count of 1000/mm3 to less than 2000 is considered Grade 3 (severe) but may not be considered serious. Seriousness (not intensity) serves as a guide for defining regulatory reporting obligations. .

How is mucositis graded in radiation therapy?
Mucositis grading scales RTOG 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).
What factors affect the clinical course of mucositis?
Several factors affect the clinical course of mucositis. In chemotherapy-induced oral mucositis, lesions are usually limited to non-keratinized surfaces (i.e. lateral and ventral tongue, buccal mucosa and soft palate) 1. Ulcers typically arise within two weeks after initiation of chemotherapy.
What is the NCI CTC scale for mucositis?
Mucositis grading scales NCI-CTC. The National Cancer Institute created originally the Common Toxicity Criteria (CTC) to aid in the recognition and grading severity of adverse effects caused by chemotherapy treatments.
