In the article by E. Speina et al., entitled “Decreased Repair Activities of 1,N6-Ethenoadenine and 3,N4-Ethenocytosine in Lung Adenocarcinoma Patients,” which appeared in the issue of Cancer Research (pp. 4351–4357), the captions for figures 5 and 6 Fig. 2. were incorrect. The correct captions appear below with the appropriate figures:

Fig. 1.

The ratio of ethenoadenine to ethenocytosine in normal lung tissues from patients with different histological types of cancer: SQ or AD. ∗∗, P < 0.005.
