title: [The porphyrin content of the erythrocytes in cancer patients].
abstract: Levels of copro- and protoporphyrin in red blood cells obtained from patients with tumors of the stomach, large bowel and thyroid are discussed. The levels of both porphyrins proved markedly increased in patients with gastric and intestinal cancer but were nearly normal in cases of benign tumor of various sites and thyroid cancer.
