Characteristics of preliminary clinical diagnosis and treatment for gastritis cystica profunda accompanied with neoplastic lesions / 中华消化内镜杂志

Objective:To investigate the clinical features, characteristics under white-light endoscopy and endoscopic ultrasonography, and treatment strategies of gastritis cystica profunda (GCP) accompanied with or without neoplastic lesions.Methods:Clinical data of 35 patients, who were pathologically diagnosed as having GCP after endoscopic or surgical resection in Beijing Friendship Hospital, Capital Medical University from January 2015 to February 2021, were retrospectively collected, including 27 patients with neoplastic lesions. The demographic information, clinical manifestations, endoscopic features, treatment methods, and pathological results of GCP were summarized.Results:Thirty-five patients with GCP were 68.26±8.08 years old, and mostly male (80.00%, 28/35). The most common symptom was upper abdominal pain, accounting for 31.43% (11/35), and 25.71% (9/35) had no symptoms. Other symptoms included acid reflux, heartburn, abdominal distension, anemia, and choking sensation after eating. The most common site of GCP was cardia (51.43%, 18/35), and the main endoscopic manifestations of GCP were flat mucosal lesions (68.57%, 24/35), mainly 0-Ⅱa and 0-Ⅱa+Ⅱc type lesions, accounting for 66.67% (16/24). The second common endoscopic manifestation was polypoid eminence (20.00%, 7/35). Endoscopic ultrasonography was performed in 15 patients, with main manifestations of uniform hypoechoic with or without cystic echo (73.33%, 11/15). Among the GCP cases, 33 patients received endoscopic resection, and 2 received surgical treatment. The treatment processes were all successfully completed, and en-bloc resection was accomplished for all lesions receiving endoscopy, with the mean endoscopic operation time of 86.13 min. One patient suffered postoperative delayed bleeding after ESD which was stopped by endoscopic hemostasis. Final pathological results showed that the proportion of GCP complicated with neoplastic lesions was 77.14% (27/35), 68.57% (24/35) with early gastric cancer or precursor. Twenty-three cases achieved R0 resection. One case showed positive basal resection margin and vascular invasion, and recurrence happened in situ at the 5th month of follow-up, surgical resection was then performed. The endoscopic complete resection rate was 95.83% (23/24).Conclusion:GCP usually occurs in middle-aged and elderly male, often located in cardia, manifested mainly as flat mucosal lesions and polypoid changes. Endoscopic ultrasonography shows a high diagnostic value for GCP, and endoscopic treatment is safe and effective minimally invasive treatment for GCP.

Diagnosis and treatment of 40 cases of gastritis cystica profunda / 中华消化内镜杂志

Objective To investigate the clinical,endoscopic and pathological features of gastritis cystica profunda (GCP).Methods A total of 40 patients with GCP confirmed by pathology who received endoscopic or surgical treatment at Renji Hospital,School of Medicine,Shanghai Jiaotong University from May 2013 to May 2018,were included in the retrospective analysis.The clinical data such as population composition,clinical manifestations,endoscopic findings and pathological results were summarized and analyzed.Results Among the 40 patients were predominantly males (75.0％,30/40),and the mean age of onset was 61.2 years.The most common sites were cardia (32.5％,13/40) and gastric antrum (30.0％,12/40).The clinical symptoms of the patients were atypical and it was difficult to diagnose GCP with routine endoscopy examination.The endoscopic findings were mostly type 0-Ⅱ (50.0％,20/40).GCP with neoplastic lesions accounted for 55％ (22/40).Unconditional logistic regression analysis showed that male (P =0.013,OR =31.093,95％ CI:2.079-464.976) and Helicobacter pylori infection (P =0.041,OR =10.225,95％ CI:1.096-95.411) were risk factors for GCP with neoplastic lesions.Conclusion GCP commonly occurs in middle-aged and elderly men,and varies in different manifestations under white light endoscopy.GCP is not a benign lesion,but can also coexist with neoplastic lesions,which are mostly differentiated intramucosal cancer.

Endoscopic diagnosis and treatment of gastritis cystica profunda with early gastric cancer / 中华消化内镜杂志

Objective To study the relationship between gastritis cystica profunda (GCP)and early gastric cancer (EGC),and to explore the diagnosis and treatment of GCP.Methods Clinical data of 17 patients,who were pathologically diagnosed as having GCP,including clinical symptoms,white light endo-scopic findings,magnifying endoscopic features,EUS outcomes and histopathological characteristics were an-alyzed.Results All 17 patients of GCP had no specific clinical symptoms or history of gastric surgery prior to the operation.Eight lesions were located at cardiac,4 at gastric body,4 at gastric antrum and 1 at gastric angle.As to the morphology,3 cases were type Ⅰ,3 type Ⅰ +Ⅱc,9 type Ⅱa +Ⅱc,1 type Ⅱc and 1 type Ⅱb +Ⅱc.The mean lesion size was 1.8 cm.Of 16 patients with preoperative EUS examination,11 patients were found to have cystic changes,with the diagnostic rate being 68.8%(11 /16).All 17 patients underwent ESD,14 (82.4%,14 /17)of which were found to have EGC.Postoperative pathology confirmed low grade intraepithelial neoplasia in 3 cases,high grade intraepithelial neoplasia in 7,intramucosal carcino-ma in 4,submucosal carcinoma in 3 patients.Conclusion EUS plays an important role in the diagnosis and treatment of GCP.And GCP is highly correlated with EGC,which should be managed in time.

A Case of Gastric Inverted Hyperplastic Polyp Found with Gastritis Cystica Profunda and Early Gastric Cancer

A gastric inverted hyperplastic polyp is a rare type of gastric polyp and is characterized by downward growth of a variety of mucosal components into the submucosa. The polyp consists of columnar cells resembling foveolar epithelium and pyloric gland epithelium and can coexist with gastritis cystica profunda. Frequently, adenocarcinoma can coexist, but the relation is not clear. A 77-year-old male underwent endoscopic submucosal dissection due to early gastric cancer. A gastric inverted hyperplastic polyp was found in the removed specimen and gastric cystica profunda was also found. We report a case of gastric inverted hyperplastic polyp coexisting with gastric cystica profunda and gastric adenocarcinoma.

A Ten-year Follow-up of a Case with Gastric Adenoma Accompanied with Gastritis Cystica Profunda Treated by Endoscopic Submucosal Dissection / 대한소화기학회지

Gastritis cystica profunda (GCP) is an uncommon hyperplastic benign lesion, and histologically characterized by hyperplasia and cystic dilatation of the gastric glands extending into the submucosal layer. GCP usually occurs at a gastroenterostomy site, although it can occasionally be found in an unoperated stomach. GCP is thought to be a possible precancerous lesion, since a few early gastric cancers associated with it were reported. Herein, we report a case of gastric adenoma associated with GCP in an unoperated patient. The sizes of both the GCP and adenoma overlying it have increased during a 10 year follow-up period. Adenoma on the latest biopsy showed low grade dysplasia, and it was successfully treated by endoscopic submucosal dissection.

Gastritis Cystica Profunda Accompanied by Multiple Early Gastric Cancers / 대한소화기학회지

Gastritis cystica profunda (GCP) is a rare disease which shows multiple cystic gastric glands within the submucosa of the stomach. GCP lesions mainly develop at the site of gastroenterostomy and exhibit benign behavior. However, there have been a number of debates over its malignant potential. Several reports have documented GCP accompanied by gastric carcinomas, but the relationship between the two conditions remains uncertain. Here we report two cases of GCP with dysplasia accompanied by synchronous multiple early gastric cancers without previous gastric surgery.

Gastric Cancer Associated with Gastritis Cystica Profunda in Patients without Previous Gastric Surgery

Gastritis cystica profunda (GCP) is an uncommom hyperplastic lesion, which is located within the submucosa. GCP may occur several years after previous gastric surgery. In some reported cases, it was a premalignant condition and may lead to carcinoma of the stomach. We report a case of a 54-year-old man with epigastric pain and dyspepsia. He had undergone peritoneal dialysis for end stage renal disease about 13 years prior. An Upper gastrointestinal endoscopy showed elevated lesion at the gastric antrum, looking like an advanced gastric cancer or gastrointestinal stromal tumor. Endoscopic biopsy results were tubular adenoma with low-grade dysplasia. When followed up 9 months later, the lesion had increased in size and symptoms remained. We therefore performed a subtotal gastrectomy. The final biopsy was adenocarcinoma arising in GCP.

A Case of Gastritis Cystica Profunda Presenting with a Submucosal Cystic Tumor / 대한소화기내시경학회지

Gastritis cystica profunda (GCP) is a lesion characterized by elongation of the gastric foveolae with hyperplasia and cystic dilatation of the gastric glands that extends into the submucosal layer. In most cases, gastritis cystica profunda develops in patients who have undergone a gastroenterostomy, with or without gastric resection. GCP may present not only as a submucosal tumor or as solitary or diffuse polyps, but GCP is also rarely seen as a giant gastric mucosal fold. A patient arrived at our hospital with dyspepsia. Gastroduodenoscopy (EGD) showed the presence of a submucosal tumor measuring 3 cm in the widest diameter in the body of the stomach. A CT scan demonstrated the cystic nature of the lesion and endoscopic ultrasound (EUS) depicted a homogeneous hypoechoic, unilocular cystic mass without any internal solid component. EGD, CT and EUS findings suggested that the lesion was more likely to be benign than malignant. The lesion was treated with an endoscopic mucosal resection (EMR), and the lesion was finally diagnosed as gastritis cystica profunda. A follow-up EGD demonstrated that all mucosal surfaces were well healed four weeks after the EMR.

A Case of Gastritis Cystica Profunda with a Long Stalk Presenting with Upper Gastrointestinal Bleeding / 대한소화기내시경학회지

Gastritis cystica profunda (GCP) is a rare disease in which hyperplastic and cystic dilatation of the gastric mucous glands extend into the tissues beneath the submucosa. GCP is mainly observed at the site of a gastroenterostomy; however, it may occur in the stomach without a previous history of surgery. GCP may present not only as a submucosal tumor or as solitary or diffuse polyps but also rarely as a giant gastric mucosal fold. In a patient without a previous history of surgery, GCP presents mainly as a sessile polypoid protrusion or as a submucosal tumor. In addition, GCP presents with non-specific symptoms and is most commonly found incidentally. We present a case of GCP that developed upper gastrointestinal bleeding and showed a long stalk and a focal ulcerative lesion on the surface of a polyp that developed in the stomach without a history of previous surgery. This lesion was removed by the use of an endoscopic polypectomy and was histologically diagnosed as GCP.

A Case of Gastric Inverted Hyperplastic Polyp Associated with Gastritis Cystica Profunda and Early Gastric Carcinoma

A gastric inverted hyperplastic polyp is characterized by downward growth of the hyperplastic mucosal components into the submucosa. Lesions are composed of hyperplastic foveolar-type glands, and sometimes coexist with gastritis cystica profunda (GCP). Adenocarcinoma frequen- tly can coexist, but the relationship is not clear. A 71-year-old male was admitted to hospital because of dyspepsia for one month. He underwent a wedge resection of the stomach, after endoscopic biopsies. The gross finding showed a slightly elevated papillary lesion with central depression. Microscopically, the elevated lesion was composed of hyperplastic fundic glands and foveolar cells, and the central depressed lesion showed a nodular inverted proliferation of normal appearing gastric epithelium and glands in the submucosa. An additional proximal gastrectomy specimen exhibited marked GCP and a minute adenocarcinoma at the proximal margin with p53 protein overexpression.

A Case of Gastritis Cystica Profunda Associated with Tubular Adenoma / 대한소화기내시경학회지

Gastritis cystica profunda (GCP) is a rare disease in which mature glandular epithelium extends into the muscularis mucosae or below. GCP lesions mainly develop at the gastroenterostomy stomas. These lesions show malignant histologic features such as metaplastic and even dysplastic alteration, however they usually exhibit benign behavior. We report a case of a patient with GCP who had not previously undergone gastric surgery. A 63-year-old woman visited our hospital for anorexia and epigastric discomfort. The esophagogastroduodenoscopy revealed two polyps on the anterior wall of the greater curvature, antrum. The polyps were removed by snare polypectomy and the histology findings showed the character of a tubular adenoma and a hyperplastic polyp with an associated GCP.

Clinical features of gastritis cystica profunda in patients without history of gastric surgery (Gastric Cancer Patients vs. Non-cancerous Patients) / 대한내과학회지

BACKGROUND: The relationship between gastric cancer and gastritis cystica profunda (GCP) has been frequently reported on, but there have been no systemic studies on whether or not GCP is a precancerous lesion. The aim of this study is to retrospectively analyze the groups in which some of the patients were accompanied by carcinoma and the other patients were non-cancerous (35 GCP cases were without previous surgery). METHODS: From February 2000 through July 2005, 35 cases of GCP without antecedent gastric surgery were diagnosed histologically. We reviewed the medical records, the endoscopic findings and the histologic findings of the patients. RESULTS: In these cases, the age ranged from 33 and 82 years (mean: 63+/-10.1 years). The endoscopic findings of GCP were various: there were 6 erosions and 9 ulcers in the cancer group and 12 polyps in the non-cancer group (p=0.000). The mean size of the lesions was 21.4+/-17.8 mm in the cancer group and 14.6+/-9.3 mm in the non-cancer group (p=0.337). Hypertension was associated with 15 cases (42.9%) in the cancer group and with 2 cases (5.7%) in the non-cancer group (p=0.000). There were 13 smokers (37.1%) in the cancer group and 6 smokers (17.1%) in the non-cancer group (p=0.028). For the histologic findings, 6 GCP patients were associated with dysplasia of adenomas, 4 GCP patients with intestinal metaplasias and 28 GCP patients (80%) with precancerous lesions and carcinomas. CONCLUSIONS: In this study, 18 GCP patients (51.4%) were associated with carcinoma and 10 GCP patients (29%) were associated with precancerous lesions. These results suggest that GCP is a precancerous or paracancerous lesion and it may be one step in the development of carcinoma. The underlying mechanisms of gastric carcinogenesis might be confirmed if we investigate the gene mutations and environmental differences of documented GCP cases that are without previous surgery.

Our Experience of Gastritis Cystica Profunda Cases and Its Clinical Study / 대한소화기내시경학회지

BACKGROUND/AIMS: Gastritis cystica profunda (GCP) is a rare disease that is characterized by a hyperplastic and cystic dilatation of the pseudopyloric gland with submucosal invasion. GCP is regarded as a benign lesion. However, there is some controversy regarding its malignant potential. This study reviewed the clinical features and association with malignancy. METHODS: From January 2001 to June 2005, 1,010 cases of resected and 1,228 cases of an endoscopic mucosal resection or polypectomy were examined. RESULTS: Thirty-nine cases (1.7%) were confirmed pathologically and were not associated with prior gastric surgery mostly. The mean age was 60.0+/-11.4 years old and there were 29 male patients. The body was most commonly located on the longitudinal axis (57.1%). Eleven cases (28.2%) were not associated any other gastric lesion, the majority of which were the polypoid type (82.0%). However, two cases were found as a hypertrophic mucosal fold, and a submucosal tumor, respectively. Seventeen cases (43.6%) were associated with early gastric cancer. CONCLUSIONS: Despite its rarity, GCP should be considered when an endoscopically polypoid lesion or submucosal tumor (SMT) is found. Because of its association with early gastric cancer or adenoma, more study will be needed to examine the relationship between GCP and gastric carcinogen

A case of gastritis cystica profunda with early gastric cancer / 대한내과학회지

We report a rare case of adenocarcinoma with multiple gastritis cystica profunda that develope in a 56-year-old man. We found early gastric cancer at the gastric angle. And some cystic lesion was present at lesser curvature of the body. Gastrectomy was performed for confirmation and treatment. Gastritis cystica profunda (GCP) is usually characterized by multiple cystic mass in the mucosa and submucosa of the stomach. It is rare disease which is mainly found at the stoma site of gastroenterostomy. Occasionally GCP develops in the stomach without previous history of surgery. Most common feature of GCP is sessile polypoid protrusion but, submucosal tumor, giant gastric mucosal fold and pedunculated mass are found. Some evidence suggests that downward adenocystic proliferation of glands is a dysplastic or precancerous change. But we know that these submucosal cystic lesion may not be precancerous. Thus cystic mass must be distinguished from Menetrier's disease, Zollinger-Eillison's syndrome, and other malignancy.

A Case of Gastritis Cystica Profunda Associated with High Grade Tubular Adenoma / 대한소화기학회지

Gastritis cystica profunda is usually characterized by hyperplastic and cystic dilatation of pseudopyloric gland with submucosal invasion. These lesions possess malignant histologic features as metaplastic and even dysplastic alteration can be observed, however they usually exhibit benign behavior. Macroscopically, gastritis cystica profunda may present as a submucosal tumor or as a polyp. In rare case, however, it can be found as a giant mucosal fold. The proposed pathogenesis of lesion relates to ischemia, chronic inflammation, and the presence of foreign body. Herein, we report a case of gastritis cystica profunda associated with high grade tubular adenoma in a patient without antecedent surgery.

A Case of Gastric Wall Abscess Associated with Gastritis Cystica Profunda / 대한소화기내시경학회지

Gastric wall abscess is a form of phlegmonous gastritis and has been very rarely reported. The pathogenesis of gastric wall abscess is thought to involve a focal injury to the gastric mucosa such as a penetrating trauma from an ingested foreign body or an endoscopic biopsy, where by bacterial infection occurs. Gastritis cystica profunda is a rare disease in which hyperplasia of mature glandular epithelium extends into the tissues beneath the submucosa. It shows multiple small cysts in the mucosa and submucosa of the stomach. To our knowledge, the association of gastric wall abscess with gastritis cystica profunda has never been reported yet. We, recently, experienced a case of gastric wall abcess associated with gastritis cystica profunda. Herein, we report it with a brief review with literatures.

A Case of Gastric Adenocarcinoma Arising from Gastritis Cystica Profunda / 대한소화기내시경학회지

Gastritis cystica profunda (GCP) is a disease characterized by gastric foveolae elongation along with hyperplasia and cystic dilatation of the gastric glands extending into the tisssue beneath the submucosa. It mainly occurs on the site of gastroenterostomy, but can occasionally be found in an unoperated stomach. GCP may present as a submucosal tumor or polyp, and rarely a giant gastric mucosal fold. This lesion has traditonally been regarded as a benign lesion. However, there are many debates over its malignant potential. Further investigations on the relation between GCP and gastric carcinoma may be necessary. To our knowledge, this is the second description of adenocarcinoma arising from GCP in an unoperated stomach.

Two Cases of Gastritis Cystica Profunda Diagnosed by Endoscopic Polypectomy / 대한소화기내시경학회지

Gastritis cystica profunda (GCP) is a rare disease in which mature glandular epithelium extends into the muscularis mucosae or below. Mainly GCP lesions developed at gastroenterostomy stomas. We experienced two cases of GCP which were not related with any gastric surgery. The first case was 76-year-old woman who visited for epigastic pain and dyspepsia. The second case was 55-year-old woman complaining right upper quadrant pain. The polyps are found on the greater curvature of the antrum at first case, and on the lesser curvature of the antrum at second case. Each polyp was successfully removed by polypectomy.

A Case of Gastritis Cystica Profunda Associated with Gastric Perforation and Hypertrophic Gastric Folds / 대한소화기내시경학회지

Gastritis cystica profunda (GCP) is a rare disease in which cystically dilated gastric foveolae or glands extend into the muscularis mucosae or below. The pathogenesis of GCP has been described as an interruption of the muscularis mucosae and migration of epithelial elements to submucosa caused by presence of suture materials after surgery or erosion of the gastric mucosa in chronic gastritis and ischemia. Macroscopically, GCP may present not only as a giant gastric mucosal folds but also as a submucosal tumor or as solitary or diffuse polyps. An endoscopic ultrasonographic (EUS) findings clearly differ from findings in the other disordes. The combination of EUS and mucosectomy appears to be very useful for the diagnosis of GCP. Therefore, all unnecessary surgical procedures should be avoided in cases of GCP. We report a case of GCP associated with gastric perforation which presented as diffuse giant gastric folds and clinically advanced gastric cancer was suspected.
