The study included all female outpatients with breast cancer who were treated with radiotherapy from January to December 2017 and met the inclusion criteria. The primary outcomes were OTT and completion rate. The secondary outcomes included the number of radiotherapy fractions, radiotherapy doses, number of radiotherapy interruption days, and reasons for radiotherapy interruption. The chi\u2010squared and Mann\u2013Whitney <jats:italic>U<\/jats:italic> tests were used to assess the differences in outcomes between two insurance schemes (JKN\u2010PBI (Beneficiaries of Health Insurance Contribution Assistance) and JKN\u2010NON\u2010PBI (Non\u2010Beneficiaries of Health Insurance Contribution Assistance)).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The sample included 285 breast cancer patients (mean age: 53\u2009years).
