Natural history of gastric cancer—a case followed up for eight years: early to advanced gastric cancer

We experienced a case of gastric cancer that was prospectively followed up for 8?years. With severe heart disease, the patient did not wish surgery or anticancer drug treatment. After informed consent was obtained, he was followed up for 8?years. He received upper gastrointestinal endoscopy every year, which revealed IIc early gastric cancer, and biopsy showed well differentiated adenocarcinoma. A flat and mildly depressed lesion with redness was observed on endoscopy, exhibiting typical morphology of IIc-type early gastric cancer. The appearance of IIc M cancer was observed macroscopically from 2000 to 2003. Four years later, surface irregularity with ulceration appeared. Then, the whole lesion was elevated, which suggested submucosal invasion, and the tumor exhibited the morphology of IIa?+?IIc or type 3. The ulcer became deeper and elevated boundaries were formed. Horizontal expansion of the flat lesion was mild, while invasion to deeper layers was predominant. Eventually, he died of heart failure. Estimated M cancer was observed for about 3?years, followed by invasion to deeper layers. Taken together, this is a valuable case that followed up the manner of invasion to deeper layers over time from early to advanced gastric cancer.     

Clinicopathological and immunohistochemical study on penetrating and superficial spreading type of early gastric cancers

Specific type of early gastric cancer based on the cancer surface area and the degree of invasion were studied by measuring digital values of the cancer surface area in early gastric cancer patients. The results indicated that the pen and super type of early gastric cancer had many clinicopathological characteristics as compared with common type of early gastric cancer. An immunohistochemical study also revealed that the pen type of early gastric cancer had a high growth activity. Moreover, it was suggested that EGF was involved in its specific invasion and growth, and that EGF and TGF-beta affected its scirrhous growth. The possibility that the poorly differentiated pen type is an early lesion of linitis plastica type gastric cancer was also considered. From these findings, it was assumed that the immunological staining of EGF and TGF-beta in biopsy specimens might be useful in the diagnosis of the pen type of early gastric cancer and also in diagnosis of early lesion of linitis plastica type gastric cancer.     

The Specificity of the Penetrating and the Superficial Spreading Types of Early Gastric Cancer—Classification of Early Gastric Cancer Using the Interactive Image Analysis System—

Abstract: Specific types of early gastric cancer were investigated in accordance with the cancer surface area and the degree of penetration by means of quantitative measurements of the surface area of early gastric cancer using the interactive image analysis system. The results indicated a significant correlation between the surface area and the penetration depth in ordinary early gastric cancer. However these correlations were not observed in both well and poorly differentiated adenocarcinoma cases of the so-called PEN and SUPER types, which showed a significant specificity when compared with ordinary early gastric cancer. The PEN and SUPER types of early gastric cancer also exhibited various clinicopathological characteristics, and it was suggested that the poorly differentiated PEN type might be the initial lesion of a linitis plastica type gastric cancer. Examination of the conditions of the mucosa surrounding the cancer revealed a difference between the PEN and the SUPER types, and this suggested that the environment at the site of a cancer growth influences the type of growth and the spread of early gastric cancer.     

Gastric tuberculosis presenting as linitis plastica: a case report and review of the literature

Gastric tuberculosis is rare and usually presents as an ulcerated lesion or gastric outlet obstruction. Rarer presentations include massive gastrointestinal bleed and gastric perforation. A case of gastric tuberculosis presenting as linitis plastica is reported here. This is the first such case report. The patient was a young woman who presented with non-specific abdominal pain and significant weight loss. The gastric mucosa appeared oedematous and hyperaemic and there was spontaneous oozing of blood on upper gastrointestinal endoscopy. Computed tomography of the abdomen revealed diffuse thickening of the gastric wall. The diagnosis was confirmed by the presence of caseating granulomas with acid fast bacilli in the endoscopic biopsy specimen. The patient showed significant clinical improvement on four-drug anti-tuberculous treatment.     

Case of early gastric cancer with nodular gastritis

A case of depressed early gastric cancer with nodular gastritis is described. A 47‐year‐old Japanese man was referred to our hospital and admitted for surgical treatment of gastric cancer. Barium upper gastrointestinal study and endoscopy examination showed a 4.5 × 3.0 cm depressed lesion with a deep central ulceration in the anterior wall of the lower corpus. An unusual miliary pattern resembling ‘goose flesh’ was observed endoscopically in the antrum. Biopsy specimens from the tumor showed poorly differentiated adenocarcinoma, and specimens from the antrum showed many lymphoid follicles with a germinal center. Immunoglobulin G antibody and histological tests (Giemsa stain) for Helicobacter pylori were both positive. Early gastric cancer with nodular gastritis was diagnosed and a subtotal gastrectomy was performed. Histological examination of the resected specimen showed a stage I tumor infiltrating a poorly differentiated adenocarcinoma with a depressed lesion in the corpus (type 0 IIc + III) and nodular gastritis in the antrum. The patient is doing well 1 year after surgery.     

Adenosquamous carcinoma of the stomach associated with separate early gastric cancer (type IIc)

Adenosquamous carcinoma originating in the stomach is a relatively rare entity. It comprises less than 0.5% of all gastric cancers. Recently, we encountered a patient with gastric adenosquamous carcinoma associated with separate early gastric cancer (type IIc). The patient was a 72-year-old man who was diagnosed as having gastric cancer in a multiphasic health screening examination conducted in May 1992. The patient subsequently underwent pylorogastrectomy. Examination of the resected specimen revealed two lesions, advanced cancer (Borrmann 2) and early cancer (type IIc). The lesions were histopathologically diagnosed as adenosquamous carcinoma and adenocarcinoma, respectively. The majority of gastric adenosquamous carcinomas are stage III or IV advanced cancers, and are treated according to the therapeutic protocol for adenocarcinomas. Their prognosis is generally poor. Continuous follow up is required for patients with these adenosquamous cancers, even after curative resection has been performed, because of the advanced nature of these lesions.     

Complete response of early gastric cancer to uracil and tegafur

A 74-year-old Japanese woman with early gastric cancer was successfully treated with uracil and tegafur (UFT). She was diagnosed by endoscopy (including endoscopic biopsy and endosonography) with an early gastric cancer, type IIa + IIc, on the greater curvature of the angulus. Surgical procedures or endoscopic therapy could not be performed because the patient had severe ischemic heart disease. Therefore, chemotherapy with UFT was administered at 300 mg/day for 15 months. Follow-up endoscopy, endosonography, and biopsy showed disappearance of the gastric cancer. To our knowledge, this is the first case report of the complete response of an early gastric cancer to UFT in the English-language literature. (Received Sept. 18, 1997; accepted Apr. 24, 1998)     

Linitis plastica-type adenocarcinoma of the esophagus: a case report

“Linitis plastica” refers to a histological characterization of diffusely infiltrating, poorly differentiated adenocarcinoma. Linitis plastica-type esophageal adenocarcinoma is extremely rare: this is thought to be only the sixth case report of linitis plastica involving the esophagus. A 60-year-old man was referred to our hospital after repeated endoscopic examinations over the course of a few months. Because he complained of dysphagia, upper endoscopy was performed, revealing stenosis with a few mucosal changes of the lower esophagus. Gastroesophageal reflux disease was initially diagnosed, but biopsy revealed adenocarcinoma. At the time of operation, peritoneal metastasis was noted. Macroscopically, the lesion was diffusely infiltrating, almost completely covered with normal squamous epithelium that showed positive staining with iodine. Pathological examination showed poorly differentiated adenocarcinoma. Despite the poor prognosis, the patient survived a comparatively long 18 months following esophagectomy with oral chemotherapy using S-1.     

Double cancer of the stomach,one AFP-producing tumor

In recent years, many cases of alpha-fetoprotein-producing gastric cancer (AFPGC) characterized by increased serum levels of alpha-fetoprotein (AFP) and AFP positivity of the gastric cancer have been reported. Here we present a case of AFPGC coexistent with a different histological type of gastric cancer: The AFPGC was Borrmann type 1 advanced gastric cancer with multiple liver metastasis and appeared to produce both AFP and des-γ-carboxy prothrombin (PIVKA-II). The second cancer was IIc type early gastric cancer and did not produce AFP. Despite receiving palliative chemotherapy, the patient died, due to hepatic failure, 45 days after admission.     

Review of five cases of early gastric carcinoma.

Five cases of early gastric carcinoma (EGC) were seen in 12 months. The clinical features did not provide guide-lines to diagnosis, which depends on air contrast barium studies, endoscopic recognition of early malignancy, adequate biopsies, and their interpretation. Malignancy was present in an average of 60% of the biopsies taken. The most common type of lesion was IIc. The superficial nature of the malignancy was predicted at endoscopy in four cases but was unsuspected in one case which was considered to be advanced carcinoma until the resected specimen was throughly examined microscopically. The excellent prognosis of EGC was discussed. Only conservative surgery need be performed if the superficial nature of the lesion is recognized before operation.     

Sarcoidosis gastropathy: diagnosis and contribution of echo-endoscopy]

We report a case of gastric sarcoidosis in a 36-year old woman. The clinical and endoscopic ultrasonography findings initially suggested linitis plastica. Subsequently the discovery of unexpected gastric and then, bronchial granulomas after bronchoscopy and bilateral ocular fixation on gallium scanning, led to the diagnosis of sarcoidosis. Endoscopic ultrasonography showed abnormal hypertrophy of the third hyperechoic layer. These findings usually suggest among the etiologies of giant gastric folds, malignant diseases and particularly linitis plastica.     

SYNCHRONOUS MULTICENTRIC SIGNET‐RING CELL CARCINOMA OF THE STOMACH

A case of simultaneous multicentric signet‐ring cell carcinoma (SRC) of stomach is presented. Initially, an early gastric cancer (IIc) was diagnosed and this was cured with distal gastrectomy. Thirty‐eight months after the operation, follow‐up endoscopy revealed a tiny mucosal discoloration lesion, which was diagnosed as a minute SRC focus with biopsy. This was successfully treated with endoscopic mucosal resection (EMR). Nine months later, gastroscopy discovered another small mucosal lesion and it was again diagnosed as a tiny SRC lesion, which was also successfully treated with EMR. After a further 2 months, endoscopy showed three small mucosal lesions (discoloration) similar to previous lesions, two of which proved to be SRC with biopsy. As these lesions distributed widely over the remnant stomach, total gastrectomy of the residual stomach was performed. Pathological examination demonstrated a total of 22 simultaneous multifocal SRC lesions, which were all very small mucosal cancer. These cancers, including previously EMR‐treated ones, seemed to develop in a multicentric manner, as they were diagnosed within 11 months. This case also indicated that even subtle endoscopic findings should vigorously be sought and, if in doubt, be biopsied in order to locate gastric cancer early enough for minimal invasive curative treatment to be feasible.     

Corrosive gastritis mimicking linitis plastica carcinoma

A 59-year-old female with depressive tendencies was admitted suffering from hematemesis and abdominal pain, two hours after ingestion of an unknown amount of toilet bowl cleaner (hydrochloric acid, pH 1.0). A barium study 24 days after ingestion revealed rigid narrowing and granulation of the entire stomach. The esophagus and duodenum were normal. The radiographic results were similar to those obtained for linitis plastica carcinoma of the stomach, but biopsy specimens of the stomach revealed no cancer cells. A total gastrectomy was performed about two months after ingestion to relieve the persistent feeling of nausea. Specimens revealed a rigid and thickening lining and a denuded mucosal surface of the stomach. The cut surface of the specimen showed a remarkable fibrous thickening of the submucosal layer. Microscopic examination failed to reveal a normal mucosal layer except in a narrow area of the fornix, and remarkable fibrosis of the submucosal lining was noted. No cancer cells were found. Corrosive gastritis has a linitis plastica appearance with a predilection for the antrum. Radiological examination revealed the very rare manifestation of a rigid narrowing of the whole stomach mimicking linitis plastica type cancer.     

Early duodenal adenocarcinoma arising in gastric metaplasia treated by endoscopic resection

Early duodenal carcinoma is a rare entity. Most duodenal carcinomas are diagnosed at a more advanced stage. This report describes the case of a 59-year-old lady with an early duodenal adenocarcinoma diagnosed at check-up gastroduodenoscopy in an outpatient clinic who was referred to us for further investigation and management. The initial upper endoscopy at our department revealed a type IIa+c lesion in the proximal duodenum (10 - 12 mm diameter, flat elevated lesion with central depression). Using chromoendoscopy and magnification endoscopy the lesion could be well demarcated and neoplastic changes in the architecture of the intestinal villi could be detected. After submucosal epinephrine-saline injection, the lesion was removed by endoscopic resection without complications. Histopathological examination revealed the rare entity of an early duodenal carcinoma arising from incomplete-type gastric metaplasia in the duodenum. In summary, the presented paper describes a case of successful endoscopic treatment of an early duodenal carcinoma arising from incomplete gastric metaplasia.     

Diffuse submucosal cysts of the stomach: report of two cases in association with development of multiple gastric cancers during endoscopic follow up

BACKGROUND: Diffuse submucosal cysts of the stomach have been suggested as a predisposing condition for the development of gastric cancer, especially multiple cancers. We report here two cases of diffuse submucosal cysts of the stomach associated with multiple gastric cancers which were detected during endoscopic follow-up. METHODS AND RESULTS: The first patient was a 75-year-old man and the second patient was a 72-year-old man. In the first case, we performed an endoscopic examination every year and detected an advanced cancer and two early cancers on the fifth year of the follow up. Because one of these cancers was advanced, we examined the second patient endoscopically every six months. In this patient, we detected two early cancers after 1.5 years follow up. CONCLUSIONS: We suggest that patients with this disorder should be examined regularly by endoscopy for the detection of gastric cancer, preferably every six months.     

Early gastric cancer. Clinicopathologic study

The incidence and clinicopathologic features of early gastric cancer encountered among surgical specimens from gastric resections for carcinoma in a recent three-year period, 1977 to 1979, at the Mallory Institute of Pathology were studied and compared with those of a pre-endoscopic period 10 years earlier, 1967 to 1969. It was found that early gastric cancer now comprises a greatly increased proportion of lesions leading to gastric resection, mainly as a result of endoscopy and biopsy of gastric ulcers of benign appearance. In the recent period, there were six early gastric cancers in a total of 22 gastric resection specimens compared with one in 27 gastric resections performed for carcinoma in the pre-endoscopy period. Five of the six patients in the recent period are alive without evidence of disease four to five years following surgical resection. The single patient in the earlier period died postoperatively. Applying the classification of the Japanese Endoscopic Society, there were three depressed or ulcerated lesions (type IIc or III), three elevated or polypoid lesions (type I or IIa), and a single flat lesion (type IIb). All three ulcerated lesions were interpreted as benign peptic ulcers on conventional upper gastrointestinal studies. Findings on endoscopic biopsy were positive in all cases (six of six). Although not encountered frequently in the United States, early gastric cancer, nonetheless, appears to be indistinguishable from the disease as it is described in Japan in terms of its pathologic morphology, growth patterns, coexistent or related lesions of the stomach, and curability by surgical resection. If early gastric cancer is to be recognized more frequently, knowledge of the disease and a high index of suspicion on the part of physicians are essential.     

Multiple depressed‐type colonic cancer (IIC)‐like configurations: metastases from gastric cancer

We present a rare case of multiple colonic metastases from advanced gastric cancer presenting colon depressed‐type multiple early cancer (IIc)‐like configuration. The case was a 74‐year‐old man who presented with a symptom of abdominal fullness. Colonoscopy and barium enema study revealed multiple IIc‐like lesions, which were shown histologically to be metastatic deposits of signet ring cell carcinoma. He had synchronous gastric cancer, which histologically demonstrated moderate to poorly differentiated adenocarcinoma with signet ring cell differentiation. In addition, he had concomitant multiple small bowel metastatic lesions. This appears to be the first published report of multiple IIc‐like colonic metastatic lesions from a gastric cancer.     

Efficacy of endoscopic surveillance of the upper gastrointestinal tract following distal gastrectomy for early gastric cancer

BACKGROUND/AIMS: How endoscopy can be used in the follow-up of the upper gastrointestinal tract in patients who underwent gastrectomy for early gastric cancer remains unclear. METHODOLOGY: Two-hundred and ten patients (137 males and 73 females, aged at initial gastrectomy 27-86, average age 56.5) were followed in the present study. Results of follow-up endoscopy of all patients, pathologic diagnoses of secondary tumors and interval between gastrectomy and detection of secondary tumor were reviewed. Cumulative incidence rate of second tumors in the upper gastrointestinal tract was then analyzed. RESULTS: Secondary tumor was observed by follow-up endoscopy in 7 patients including two gastric, one esophageal, one duodenal carcinoma and 3 gastric adenomas. The interval between initial gastrectomy and diagnosis of secondary tumor ranged from 20 to 71 months (average 51.7 months). All carcinomas were early stage and localized within the mucosa. Three patients with secondary cancer were successfully treated by endoscopic mucosal resection. The cumulative incidence rate of secondary cancer in the gastric remnant, esophagus and duodenum at six years after initial gastrectomy was 1.0, 0.8 and 0.5%, respectively. The overall incidence rate of secondary tumors of the upper gastrointestinal tract at six years after distal gastrectomy was 4.1%. CONCLUSIONS: The present findings indicate that annual follow-up endoscopy of the upper gastrointestinal tract after gastrectomy for early gastric cancer can be introduced to detect carcinoma at an early stage, thus improving the survival rate of gastrectomy patients.     

Upper gastrointestinal bleeding as a metastatic manifestation of breast cancer: a case report and review of the literature.

CASE PRESENTATION: A 64-year-old woman with known metastatic lobular breast cancer presented with fever, epigastric pain, hematemesis, and melena. A bleeding, ulcerated gastric metastasis was found and was treated with endoscopic therapy, omeprazole, and hormonal therapy. The patient was alive and well 13 months later. The bleeding was probably precipitated by necrosis of the lesion during chemotherapy. DISCUSSION: Gastrointestinal tract metastases from primary breast carcinoma are present in 14% to 35% of cases in autopsy series, with gastric involvement in 6% to 18% of cases. Recognized much less commonly during life than in autopsy studies, they can occur anywhere in the gut and can mimic virtually any gastrointestinal disorder. Endoscopy and barium studies facilitate diagnosis. Gastric lesions that have been noted include "linitis plastica", nodules, polyps, and ulcers. They are usually due to lobular breast carcinoma and resemble primary gastric carcinoma on microscopy. Reported cases of bleeding gastric metastases have been treated successfully with various local and systemic modalities. The median survival time of reviewed cases was four months from presentation (with a range of zero to 24 months). CONCLUSIONS: Gastrointestinal metastasis is an underdiagnosed complication of breast cancer. Gastrointestinal bleeding from metastatic breast cancer is an uncommon presentation that is readily diagnosed and that can be treated successfully by endoscopic hemostatic therapy.     

Primary linitis plastica of the rectum

Linitis plastica of the rectum is an uncommon entity that is difficult to diagnose due to the lack of mucosal lesions on endoscopy, the low diagnostic yield of biopsy and non-specific findings of barium radiology and computerized tomography. Rectal endoscopic ultrasonography has had a radical impact on the differential diagnosis of stenosing lesions of the rectum, among them linitis plastica, allowing diagnosis of this lesion even in patients with negative results of biopsy.
