Mechanisms responsible for the protective effects of higher height and weight on lung cancer remain speculative: It has been shown that, in patients with resectable lung cancer, BMI is inversely correlated with plasma C‐reactive protein levels [9] and directly with prealbumin levels [5] as well as with total psoas or total muscular areas [9, 29], suggesting that lung cancer patients with higher BMI have a more preserved nutritional status and less frequent systemic inflammation and sarcopenia, these parameters representing positive and negative predictive factors, respectively [6, 7, 8, 10]. The gene discussed is TTR; the disease is sarcopenia.
