Urinary pteridines on patients suffering from cancer. A comment on the method and results of Rao and associates and of Trehan and associates.
A diagnostic test for detecting malignancies has been reported by Rao and associates. This test has been extended by Trehan and associates as an index of disease status in acute myeloblastic leukemic patients on antileukemic drugs. The authors were able to demonstrate that by using the described assay various pteridines are measured and not exclusively 6-hydroxymethylpterin as reported by the above-mentioned authors. Furthermore, the urinary component which correlates to the status of malignant disease has to be interpreted as being neopterin. This conclusion can be drawn from previous studies conducted by the authors' laboratory.

Urinary 6-hydroxymethylpterin levels accurately monitor response to chemotherapy in acute myeloblastic leukemia.
In our earlier study it was shown that patients with various types of cancer excrete three- to 20-fold higher levels of urinary 6-hydroxymethylpterin as compared to patients with nonmalignant diseases or normal volunteers. In the present study urinary 6-hydroxymethylpterin levels have been measured as an index of disease status in acute myeloblastic leukemic patients on antileukemic drugs. The daily excretory pterin levels and the values of respective blast counts have been graphically presented for four cases with the chemotherapeutic regimens. Remission of the disease was marked by a rapid drop in the urinary 6-hydroxymethylpterin levels and correlated very well with the percentage of blasts. In another study the percentage of blasts and the urinary 6-hydroxymethylpterin were determined simultaneously in four patients undergoing chemotherapy. The data conclusively show that the simple noninvasive determination of urinary 6-hydroxymethylpterin levels accurately and rapidly reflects the status of the disease under treatment and could conveniently be employed as a suitable index for monitoring the effect of chemotherapy as well as the condition of the residual extramedullary leukemic infiltration.
