Analysis of clinicopathologic characteristics and risk factors for missed diagnosis in synchronous multiple early gastric cancer

Q: What is the main goal of the study?

To enhance detection of synchronous multiple early gastric cancer by analyzing clinicopathological features, correlations between main and minor lesions, and risk factors for missed diagnoses.

Q: How were patients selected for analysis?

A cross-sectional review included 130 patients diagnosed with SMEGC or GHGIN among 2,580 patients who underwent endoscopic submucosal dissection (ESD) at Nanjing Drum Tower Hospital, using specified exclusion criteria.

Q: Which factors were identified as independent risks for missed diagnoses?

Small and non-primary lesions were independent risk factors for missed diagnoses, and the hospital grade at the first gastroscopy was also reported as a risk factor.

Study aims to improve detection of synchronous multiple early gastric cancer (SMEGC) by evaluating clinicopathological characteristics, examining correlations between main and minor lesions alongside gastric high-grade intraepithelial neoplasia (GHGIN), and determining risk factors linked to missed diagnoses. Cross-sectional analysis enrolled 130 patients with SMEGC or GHGIN undergoing endoscopic submucosal dissection (ESD) at Nanjing Drum Tower Hospital. Lesion main/minor status was assessed using size, location, endoscopic morphology, histopathology, invasion depth, and vascular invasion. Missed diagnoses occurred in 37 patients, with small non-primary lesions and certain endoscopy timing/setting factors associated with higher risk.

Method A cross-sectional analysis included 130 patients with SMEGC or GHGIN undergoing endoscopic submucosal dissection (ESD) at Nanjing Drum Tower Hospital. Clinicopathological characteristics were evaluated, with lesions classified as main or minor. Correlations between lesions were assessed based on size, location, endoscopic morphology, histopathology, invasion depth, and vascular invasion. Risk factors for missed diagnoses were analyzed. Results Of 2580 patients treated with ESD, 130 with SMEGC or GHGIN were included in this study. The sizes ofthe main and minor lesions were positively correlated (r =0.658, p< 0.001) . The main and minor lesions showed moderate consistency in pathological type (kappa =0.421, p< 0.001) and low consistency in endoscopic morphology, depth of invasion, and longitudinal position (kappa < 0.4, p< 0.05). Of 130 included patients, diagnoses for 37 were missed. Small and non-primary lesions were independent risk factors for missed lesions. We also found that the hospital grade at first gastroscopy was a risk factor for missed diagnosis. Conclusions Endoscopists should be aware of the risk factors associated with SMEGC and consider the correlation between the main and minor lesions to prevent the oversight and misdiagnosis of SMEGC. Keywords SMEGC · HGIN · Main and minor lesions · Clinicopathologic characteristics · Missed diagnosis Introduction Early gastric cancer (EGC) refers to gastric cancer that is confined to the mucosa or submucosa, regardless of the presence of regional lymph node metastasis (Kajitani 1981; Sano et al. 1992).
