A study was made of the effect of ascorbic acid deficiency and low levels of lysine, methionine and threonine on the cancerogenic effect of nitrosopiperidine which was fed to guinea-pigs with drinking water in a single dose of 4.25 mg/kg bw. Deficiency of the nutrients given alone or especially in combination speeded up the growth tumors induced by the cancerogenic agent. A possibility of inducing esophageal tumors in guinea-pigs has been demonstrated for the first time.
