Purpose of the guideline: In recent years, antibody-drug conjugates (ADC) have gradually become one of the hottest research fields related to cancer treatment. Among the approved ADCs, HER-2 is the most explored target. However, the off-label use of anti-HER-2 ADC is common. Based on drug labels, guidelines, expert consensus and published literature evidence, this consensus systematically sorts out and conducts evidence-based evaluation of the off-label use of anti-HER-2 ADC. And the consensus expert group forms recommendations for the off-label use of anti-HER-2 ADC in order to providing reference for the clinical rational use of anti-HER-2 ADC.
