In comparison with healthy age- and sex-comparable subjects, a significantly higher concentration of unconjugated 3-hydroxyanthranilic acid was detected in the urine of untreated bladder and kidney carcinoma patients. Because of tryptophan metabolite 3-hydroxyanthranilic acid is suspected to be involved in
