Bone metastasis as a recurrence of early papillary adenocarcinoma of the stomach

High-grade Papillary Early Gastric Carcinoma With High Risk for Lymph Node Metastasis and Poor Prognosis: A Clinicopathologic Study of 96 Cases Among 1136 Consecutive Radical Gastrectomies

Papillary early gastric carcinoma (EGC) is believed to have a low risk of lymph node metastasis (LNM) and thus can be resected endoscopically. We observed anecdotally that some papillary EGC tumors showed conspicuous high-grade dysplastic features, but the significance of these observations is unknown. In this bicenter study we investigated papillary EGCs that were divided into high-grade (n=96) and low-grade (n=118) groups among 1136 consecutive EGC radical resection cases. Concurrent 464 well-moderately differentiated tubular EGCs were served as the control group. Compared with low-grade papillary and well-moderately differentiated tubular EGCs, high-grade papillary EGC displayed significantly larger sizes (mean 2.51 cm), higher frequencies of the elevated macroscopic type (51%), lymphovascular invasion (LVI) (38.5%), and LNM (31.2%). Low-grade papillary EGCs exhibited a higher prevalence of the elevated macroscopic type, but not LVI nor LNM, compared with tubular EGC. Independent risk factors for LNM included high-grade histology, female sex, distal location, submucosal invasion, and LVI. The 5-year overall survival rate was significantly lower in high-grade (79.6%) papillary than in low-grade (88.9%) papillary or tubular (92.8%) EGCs, while no significant difference in prognosis was observed in the latter 2 groups. Age of 66 years or older and LNM were independent risk factors for overall survival. In conclusions, high-grade papillary EGC was associated with high frequencies of LVI, LNM, and poor prognosis, and thus unsuitable for endoscopic therapy, while low-grade papillary EGC showed clinicopathologic features and prognosis similar to well-moderately differentiated tubular EGC and may be treated endoscopically in appropriate clinical settings.

Analysis of pathological characteristics and nursing intervention of patients with gastric polyps based on image stitching algorithm and endoscopy

Objectives:

The paper uses image stitching algorithm to understand the clinical and pathological characteristics of gastric polyps under gastroscope, and provides objective basis for the clinical diagnosis and treatment of gastric polyps and nursing intervention.

Methods:

The endoscopic, pathological data and surgical conditions of 111 patients with gastric polyps detected in the hospital from January 2017 to August 2019 were retrospectively analyzed.

Results:

The elderly patients (≥60 years old) in this group were those with high incidence of gastric polyps (56.8%); 80 patients with single polyps (72.1%), 31 patients with multiple polyps (27.9%); polyps were mainly located in the stomach (53.2%); polyps diameter ≤0.5cm are more common (69.4%); polyps are mainly hyperplastic polyps (40.5%) and inflammatory polyps in 37 cases (33.3%). Polyps were removed by biopsy forceps in 30 cases, endoscopic submucosal injection of 0.9% NaCl solution combined with high-frequency electrosurgical removal of 54 cases, endoscopic mucosal resection (EMR) in 6 cases, and endoscopic submucosal dissection (ESD) in treatment of the 4 cases, the remaining 17 cases were treated with surgery, and 12 patients were followed up, 2 of whom relapsed.

Conclusion:

Gastric polyps are small in diameter and mostly single; polyps are mainly located in the stomach body, mainly hyperplastic polyps; treatment methods are mostly endoscopic resection, and there is a possibility of recurrence after polypectomy, and follow-up should be strengthened. Full preparation before the operation, close cooperation during the operation, and careful postoperative care are important links to ensure the safety of the operation and reduce complications such as upper gastrointestinal bleeding.
