Figure 1
Trends in serum lactate dehydrogenase (LDH), urine homovanillic acid (HVA), and urine vanillylmandelic acid (VMA) concentrations versus the time since diagnosis. LDH concentrations were increased just before blood cells recovered, and the next high-dose chemotherapy (HDC) was started. LDH reflected disease activity better than VMA or HVA.

The radiologist concluded that the interior was necrotic. D: CT just before surgery. E, F, G, H: CT showing disseminated recurrence during radiotherapy.
