Anti-EGFR Therapy: Mechanism and Advances in Clinical Efficacy in Breast Cancer

Table 1

Response criteria and evaluation ratings used in the classification of clinical efficacy and safety/toxicity scoring of anti-EGFR therapies for solid tumors. General classification schemes used in review of clinical efficacy and safety, WHO criteria [24].

General classification schemes used in review of clinical efficacy and safety:
Objective response and tumor response were evaluated by the WHO Criteria [24].
Adverse events (AEs) were assessed at each cycle using the common toxicity criteria (CTC).
Cardiac failure/cardiac toxicity was graded based on the NYHA classification system.
The Cardiac Review and Evaluation Committee (CREC) evaluates cardiac dysfunction.
Factors for clinical efficacy of treatment:
In an intent-to-treat (ITT) population, in order to evaluate the overall response rate of the individual “patient-drug interaction.”
Overall response (OR): complete response (CR) + partial response (PR)
Clinical benefit (CB): complete response (CR) + partial response (PR) + stable disease (SD) 6 months
Time-to-disease-progression (TTP): the time from randomization (randomized initiation of drug/therapy.
Treatment regimen to be tested) to “disease-progression” or death (whichever event occurs first).
