Abstract:
Objective:To analyze the consistency of gastroscopic biopsy in the diagnosis of high grade intraepithelial neoplasia(HGIN) and postoperative pathological diagnosis, and explore the risk factors associated with missed diagnosis of HGIN.
Methods:From January 2012 to December 2018, the clinical data of 63 patients who were diagnosed with HGIN by gastroscopic biopsy prior to operation and underwent complete resection in the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were retrospectively analyzed. There were 55 males and 8 females, with a median age of 60 (35 to 76) years old. The gender, age, endoscopic lesion shape, longest diameter, CT image and inflammatory markers were analyzed, to investigate the correlation between them and pathological upgrading after operation. Receiver operating characteristic (ROC) curve was drawn to analyze the cut off value of measurement data, and the comparison of count data was performed by chi-square test or Fisher exact probability method. Univariate analysis was used to screen potential risk factors, and multivariate logistic regression analysis was futher utilized to analyze the independent risk factors of postoperative pathological upgrading.
Results:A total of 63 patients were enrolled, including 47 cases underwent surgical resection and 16 cases underwent endoscopic submucosal dissection(ESD). Among them, 19 patients(30.2%) were pathologically diagnosed with HGIN, while 44 patients(69.8%) were pathologically diagnosed with invasive cancer after resection. Preoperative contrast-enhanced CT showed that 11 patients(17.5%) with perigastric fat spiculation around the lesion, all of which were confirmed as invasive carcinoma after operation. Univariate analysis showed that the longest diameter of the lesion ≥2 cm (P=0.002), ulcer lesions under gastroscopy (P=0.013), platelet to lymphocyte ratio (PLR) ≥103 (P=0.030), lymph node enlargement (P=0.046) and spiculation of the perigastric fat (P=0.025) were significant differences between the groups. Logistic regression analysis showed that the longest diameter of the lesion ≥2 cm (P=0.033) and ulcer lesions under gastroscopy (P=0.007) were independent risk factors for predicting postoperative pathological upgrading.
Conclusions:Gastroscopy biopsy in the diagnosis of high-grade intraepithelial neoplasia of the stomach has poor consistency with pathological diagnosis after operation. Clinicians should take active surgical intervention, especially for cases with the longest diameter of the lesions ≥2 cm, ulcer or perigastric fat spiculation on CT.
