Comparison of reductions in serum FLC concentrations at 5, 12, and 21 d. Results presented as patients who completed FLC removal HD with (clear boxes, n = 6) and without (shaded boxes, n = 13) a break in their chemotherapy. Patients with uninterrupted chemotherapy had a more rapid and sustained reduction in their serum concentrations of FLCs, P < 0.0001. The median percentage of presenting FLC concentration at day 5 was 63% (range 49 to 100); day 12, 81% (range 43 to 100); and day 21, 94% (range 43 to 100) in patients with interrupted chemotherapy; compared with 39% (range 29 to 63), 30% (range 12 to 73), and 15% (range 5 to 59) in those patients with uninterrupted chemotherapy.
