Variations in plasma EBV DNA concentration in NPC patients treated with radiation therapy and sampled weekly during the course of treatment. The variation in plasma EBV DNA levels for each patient over time is plotted in a separate graph. The scale of the Y axis has been optimized for the concentration range for each case. X axis, time from the start of blood sampling, with the first day of radiotherapy treatment as day 0. Y axis, the plasma EBV DNA level (in copies/ml).

Variations in plasma EBV DNA concentration in NPC patients treated with radiation therapy and sampled daily during the first treatment week and then weekly during the subsequent treatment course. The variation in plasma EBV DNA levels for each patient over time is plotted in a separate graph. The scale of the Y axis has been optimized for the concentration range for each case. X axis, time from the start of blood sampling, with the first day of radiotherapy treatment as day 0. Y axis, the plasma EBV DNA level (in copies/ml).

Half-life analysis for plasma EBV DNA decay. The natural logarithm of the plasma EBV DNA concentration (Y axis) is plotted against time (X axis) for the period between the third and seventh weeks of radiation therapy. For patient 2969, the coefficient of correlation (r2) was 0.965, and the slope was −0.172, resulting in a half-life of 4.0 days. For case 0332, r2 was 0.933, and the slope was− 0.127, resulting in a half-life of 5.5 days. For case 0480, r2 was 0.966, and the slope was −0.158, resulting in a half-life of 4.4 days.
