As summarized in Table 1, among all of the tumor samples that were analyzed, 30 (17.86%) demonstrated strong ATF4 staining (score of 9–12; Fig. 1A), 43 (25.60%) showed moderate staining (score of 5–8; Fig. 1B), 44 (26.19%) had weak staining (score of 2–4; Fig. 1C), and 51 (30.35%) exhibited negative staining (score of 0–1; Fig. 1D).
