Lung cancer is the leading cause of death by cancer, and is a major sanitary concern worldwide. Some nutrients, such as -9 fatty acids, have been proposed as anticancer agents. Thus, an olein-enriched diet was assayed in a murine model of lung adenocarcinoma (LAC-1) to evaluate neoplastic and paraneoplastic evolution in BALB/c mice. The organic assimilation of dietary fatty acids was confirmed in liver by gas chromatography. This experimental oleic acid-containing diet increased animal survival and tumour latency (analysed by the Kaplan-Meier method), improving neoplastic evolution and general status, with weak effects on the paraneoplastic syndrome (thymus atrophy, splenomegaly, splenocyte response to mitogen, blood anaemia, and leucocytosis). Tumour lipid oxidation was not involved. Thus, diet enrichment with olein, a natural source of the -9 oleic acid, significantly delayed progression of LAC-1 and increased tumour latency and mice survival. These results support its use in nutritional management of cancer, with further studies being encouraged.
