Provide recent original chest CT images and pneumonitis history for lung toxicity risk assessment 4. Prepare blood counts, liver and kidney tests and current medicines to plan safety monitoring Questions to clarify - Do I meet the eligibility criteria? - What are the separate medical and coordination service costs without Chinese health insurance or free-drug assistance? - How are initial treatment, ongoing treatment, return travel and follow-up arranged? - Which risks require immediate contact with the hospital? An initial service consultation does not replace medical assessment.
