Inequalities in lung cancer: a world of EGFR

Epidermal growth factor receptor gene (EGFR) mutation status has emerged as a crucial issue in lung cancer management. Availability and cost of tests and tyrosine kinase inhibitors (TKIs) may vary as a function of country development.We conducted a prospective specialist opinion survey to map EGFR test and EGFR-TKI availability and detect associations with the Human Development Index (HDI). A questionnaire was sent to specialists in thoracic oncology in all United Nations Member States.We obtained responses from 74 countries, comprising 78% of the worldwide population. Nonresponding countries had significantly lower HDI rank than responding countries. EGFR mutation analysis was routinely available in 57 countries (70% of the worldwide population). The cost of the test was
