Analysis of gastric background mucosa and lesion characteristics of early gastric cancer in older adults
Objective To compare the characteristics of background mucosa,lesion features,and the efficiency of endoscopic submucosal dissection(ESD)between elderly and non-elderly patients with early gastric cancer(EGC).Methods This study retrospectively collected data on patients with EGC who underwent ESD treatment at Beijing Hospital from April 2020 to December 2022.The clinical characteristics,background mucosa,lesion features,ESD outcomes,and pathological results of the patients were analyzed to compare the differences between elderly and non-elderly patients.Results A total of 100 patients with EGC were selected,comprising 57 patients in the elderly group and 43 patients in the non-elderly group,with a total of 111 lesions identified(64 lesions in the elderly group and 47 lesions in the non-elderly group).The proportion of patients with a history of chronic atrophic gastritis was significantly higher in the elderly group(89.5％、51/57)compared to the non-elderly group(74.4％、32/43),with a statistically significant difference(P=0.047).Additionally,the difference in the extent of atrophy between elderly patients with EGC and their non-elderly counterparts was statistically significant(P=0.022).Among these patients,the proportion of those classified as Kimura-Takemoto C0 to C1 in the elderly group(15.6％、10/64)was lower than that in the non-elderly group(40.4％、19/47).In contrast,the proportion of patients classified as C2 to C3 in the elderly group(65.6％、42/64)was higher than that in the non-elderly group(51.1％、24/47),and the proportion of those classified as O1 to O3 in elderly patients(12.5％、8/64)was also higher than in the non-elderly group(4.3％、2/47).Furthermore,the difference in the extent of intestinal metaplasia between elderly and non-elderly patients with early gastric cancer was statistically significant(P=0.007).The overall proportion of total intestinal metaplasia in elderly patients(85.9％、55/64)was significantly higher than that in non-elderly patients(61.7％、29/47).Notably,the proportion of patients exhibiting extensive intestinal metaplasia(intestinal metaplasia present in both the gastric antrum and gastric body)was greater in the elderly group(43.8％、28/64)compared to the non-elderly group(23.4％、11/47).The Kyoto gastric cancer risk endoscopic score for elderly patients with EGC was(2.43±1.28)points,significantly higher than that of the non-elderly group(1.72±1.41)points,with a statistically significant difference observed(t=2.778,P=0.006).No statistically significant differences were observed in the proportions of total resection rates,R0 resections,curative resections,or postoperative complications following ESD when comparing elderly patients with EGC to their non-elderly counterparts.Conclusions The proportion of extensive atrophy and intestinal metaplasia was higher in the background mucosa of elderly patients with EGC,and correspondingly,the Kyoto endoscopic gastric cancer risk score was elevated.Therefore,endoscopic examinations for elderly patients with chronic atrophic gastritis should be conducted with greater care and comprehensiveness.
