Endoscopic features of superficial esophageal squamous cell carcinoma in patients with very low risk factors (female, non-drinking, and non-smoking): a case-control study

We examined the endoscopic features of superficial esophageal squamous carcinoma in patients with very low risk factors. Methods: In this single-center case-control study, 666 patients with 666 superficial esophageal squamous carcinoma lesions were divided into 2 groups: those with very low risk factors (very-low-risk group, n = 34) and those with any risk factors (any-risk group, n = 632). After case-control selection at a 1:5 ratio, the very-low-risk group comprised 34 patients and the any-risk group comprised 170 patients. We compared the baseline characteristics, endoscopic findings, and treatment results (including pathological diagnosis) between the two groups. Results: There were no statistically significant differences between the two groups in age, tumor size, tumor location, tumor morphology, or treatment results (including tumor depth and lymphovascular invasion). A longitudinal lesion with an attachment of white keratinized epithelium was more likely to be detected in the very-low-risk group than any-risk group (61.8% versus 17.6%, respectively; P
