Exploration of Targeted Anti-tumor Therapy

Difficulties	Concerns
Incomplete patient visit data and protocol violations due to delayed or deleted visits	Loss of compliance with GCP
Radiologists mainly dedicated to performing chest CT scan in COVID-19 patients	Avoid infection for both cancer patients and healthcare professionals
Several data lost
The continuum of care could not be guaranteed
