Surgical results of proximal gastrectomy for early-stage gastric cancer: jejunal interposition and gastric tube reconstruction

Background. The frequency of tumors in the upper one-third of the stomach has been increasing. The standard operation for proximal gastric cancer has been total or proximal gastrectomy. The aim of this study was to present the pathologic and surgical results of 30 patients with early-stage proximal gastric cancer managed by proximal gastrectomy. Methods. A consecutive series of 30 patients who underwent proximal gastrectomy for early-stage proximal gastric cancer was studied. Sixteen patients underwent jejunal interposition, while 14 underwent gastric tube reconstruction, which consisted of a direct anastomosis between the esophagus and the remnant of the tube-like stomach. Results. Twenty patients (67%) had no abdominal symptoms and the lesions were detected by screening gastric fiberscopy. The tumors were mostly located along the lesser curvature (73%), were grossly depressed type (IIc) (70%), and histologically well differentiated type (63%). The depth of wall invasion was the mucosa in 12 patients, submucosa in 15, and muscularis propria in 3; lymph node metastasis was absent in 28 patients (93%). When compared with patients with jejunal interposition, patients with gastric tube reconstruction had a shorter operation time (327 vs 165 min), less blood loss (508 vs 151 g), and shorter hospital stay after operation (31 vs 17 days). Endoscopy and 24-h pH monitoring showed no evidence of reflux esophagitis, except in 1 patient with gastric tube reconstruction, and no patient died of recurrence. Conclusions. Early-stage proximal gastric cancer can be successfully treated by proximal gastrectomy. Since gastric tube reconstruction is a simple, easy, and safe procedure, proximal gastrectomy followed by gastric tube reconstruction is recommended for patients with early-stage proximal gastric cancer.

Long-term survival after perforation of advanced gastric cancer: Case report and review of the literature

Although the standard operation for early cancer of gastric cardia is proximal gastrectomy followed by jejunal interposition, we recently reported a simple and useful technique for proximal gastrectomy with gastric tube reconstruction. The operative procedures included resection of the proximal two-thirds of the stomach, followed by anastomosis between the esophagus and gastric tube, using a circular stapler (Proximate ILS 25; Ethicon, Cincinnati, OH, USA). The gastric tube was about 20 cm long and 4 cm wide. The patient a 76-year-old man had no reflux symptoms such as heartburn, retrosternal pain, and regurgitation. Endoscopy showed no evidence of reflux esophagitis, including mucosal redness, erosion, and ulceration. Ambulatory 24-h pH monitoring indicated that the pH of the lower esophagus was between 6 and 8 when the patient was upright and between 5 and 7 when he was in the supine position. There were nine reflux episodes during the day, and no reflux episode while he was asleep. The duration of each reflux episode was less than 1 min, and the total reflux time was 1 min in the 12-h day (0.1%). These data indicate that reconstruction by gastric tube may prevent esophageal reflux in patients who have undergone proximal gastrectomy for early cancer of the gastric cardia.

Histologic and serum risk markers for noncardia early gastric cancer

Corpus dominant gastritis and intestinal metaplasia (IM) are considered markers of increased risk of gastric carcinoma. The aim of our study was to determine serum and histologic risk markers of gastric cancer. Antral and corpus histology, pepsinogen and gastrin 17 levels were compared among patients with history of endoscopic mucosal resection (EMR) for early gastric cancer and controls. Serum pepsinogen (PG) and gastrin 17 levels were measured by RIA. There were 53 gastric cancer patients and 75 controls. The scores for IM in each region and atrophy at the lesser curvature of the corpus were significantly higher in the cancer group than in the H. pylori-positive control group. IM at the greater curvature of the corpus and atrophy at the lesser curvature of the corpus were associated with multiple malignant lesions. Although corpus gastritis was associated with an increased risk of gastric cancer (odds ratio [OR] = 3.4; 95% confidence interval [CI] 1.6-7.0) (p = 0.001), the most important marker was the presence of IM at the lesser curvature of the corpus (OR = 15.1; 95% CI 4.3-52.6) (p < 0.001)). The best cut-off points of serum markers for gastric cancer were a PG I concentration of 45 ng/mL or less and a gastrin 17 >60 pg/mL (sensitivity = 83%; specificity = 68%). IM at the lesser curvature of the corpus and the combination of serum gastrin 17 and PG I identified a group at high risk for development of gastric cancer. Annual endoscopic follow-up is warranted for patients with IM found at the greater curvature of the corpus.     

Rare case of early mucosal gastric cancer presenting with metastasis to the bulbar conjunctiva

Early gastric cancer has an excellent outcome following surgical treatment. In particular, mucosal gastric cancer (m-cancer) very rarely results in metastatic dissemination and may be successfully treated by local surgical resection. We report a 64-year-old Japanese woman who presented with a recurrent cystic lesion on the left bulbar conjunctiva, with a biopsy specimen revealing metastatic signet-ring cell carcinoma. Gastrointestinal investigations revealed an early gastric cancer in the lesser curvature of the stomach. Biopsy specimen of the gastric lesion indicated poorly differentiated adenocarcinoma, which was identical to findings in the lesion in the bulbar conjunctiva. She underwent a distal gastrectomy and made an uneventful recovery. Histopathological analysis indicated a gastric signet-ring cell carcinoma that was limited to the mucosal layer, without evidence of lymphatic spread. Although the exact mechanism of metastatic dissemination to the bulbar conjunctiva is unclear, this case is very unusual, because ocular metastases almost invariably occur in the context of documented and established malignant disease. This is, to our knowledge, the first reported case of a patient with gastric mucosal cancer who presented with a conjunctival metastatic deposit and who subsequently received curative surgical treatment for both conditions.

A case of superficial esophageal cancer with metastasis to the gastric wall

A 65-year-old man with superficial esophageal cancer associated with gastric wall metastasis is presented. He had suffered from epigastralgia and dysphagia for two months. X-Ray and endoscopic examination revealed esophageal erosion at the right wall of the lower esophagus and a large gastric submucosal tumor at the lesser curvature of the upper and middle stomach. Resection of the lower esophagus and total gastrectomy were performed. Histologically, the erosion of the lower esophagus was moderately differentiated squamous cell carcinoma invading as deep as the submucosal tissue and the tumor of the stomach was metastasis of the esophageal cancer. Intramural metastasis of esophageal cancer was discussed.     

A carcinoma of the reconstructed gastric tube after a radical esophageal cancer operation

Reported are five patients who developed a carcinoma of the reconstructed gastric tube. In 3 of the 5 patients, the esophageal cancer was preceded by a gastric cancer, and the intervals before the gastric cancer was detected were 34, 24, and 60 months. The gastric tube the had been reconstructed by the retrosternal rout was resected with a median sternotomy in cases 1 and 2. In case 3, since a liver and lung metastasis had been detected by routine examination, surgery was not performed. Cases 4 and 5 had an esophageal cancer associated with a simultaneous early gastric cancer located in the lesser curvature of the upper body. Thus, a esophagectomy and a partial gastrectomy were performed. Twenty-eight and 21 months later, respectively, an early gastric cancer was found at the stump of the gastric tube that had been reconstructed by the retrosternal route. Endoscopic laser therapy was subsequently employed for both patients. Because of these findings, the author have concluded that postoperative serial examination of the gastric tube are very important, since cases of a gastric tube cancer are increasing.     

Double Primary Cancers in Extragastric Sites with Gastric Cancer: Report of Six Cases and Literature Review

OBJECTIVE To explore the clinical features, pathologic characteristics and prognosis of double primary malignant tumors with involvement of the stomach and an extragastric site. METHODS We reviewed the records of 496 patients who underwent surgery for gastric cancer in our department from January 2004 to December 2006. Synchronous double primary cancer was defined as an extragastric cancer diagnosed within a 6-month interval before the detection of gastric cancer; any gastric cancer metastasis to other areas of the body was excluded. RESULTS Synchronous and metachronous double primary cancers were identified in 1 and in 5 patients, respectively. The extragastric sites of the primary tumors in patients with gastric cancer were esophagus in 1 case, right colon in 1, rectum in 1, breast in 2 and lung in 1. Following gastric surgery, 5 patients died (within 2 mon, 24 mon, 30 mon, 48 mon and 60 mon). Only 1 patient has survived and remains disease free. CONCLUSION The prognosis of patients with gastric cancer and a second primary is relatively poor. It is necessary to perform regular esophagogastroduodenoscopy (EGD) on patients who have been diagnosed with extragastric cancer, regardless of their symptoms.     

The pathogenesis of adenocarcinoma of the stomach after successful radiotherapy of squamous cell carcinoma of the lower intrathoracic esophagus--case report

A case of a gastric cancer developed 3 years and 11 months after radiotherapy for esophageal cancer is reported. A 76-year-old man with a squamous cell carcinoma of the lower intrathoracic esophagus had received 50 Gy of irradiation as treatment. Thereafter, signs of the esophageal cancer disappeared radiologically and endoscopically, and a pathological biopsy of specimens taken from the site revealed no further cancer cells. The patient remained well for 3 years and 11 months after radiotherapy, at which time he again was admitted to hospital, having been diagnosed as having a gastric cancer. On admission, an upper G-I series showed a shadow defect along the lesser curvature of the upper-middle stomach but no evidence of any stenosis in the lower intrathoracic esophagus. Endoscopically, the mucosal surface of the esophagus was normal, and biopsy specimens taken from the site in the esophagus that had been treated with irradiation 3 years 11 months ago revealed no recurrence of his esophageal cancer. Endoscopical examination of the stomach showed an infiltrative tumor with ulceration, and a subsequent histological examination revealed a poorly differentiated adenocarcinoma. Upon a laparotomy, a metastasis was detected in the perigastric and paraaortic lymph nodes and the cancer had invaded the retroperitoneum. The stomach could not be removed and he died 3 months after the laparotomy.     

Pedunculated gastric tube interposition in an esophageal cancer patient with prepyloric adenocarcinoma

Gastric carcinoma is one of the malignancies that are most frequently associated with esophageal carcinoma.We describe herein our device for advanced esophageal cancer associated with early gastric cancer in the antrum.A 57-year-old man presenting with dysphagia and upper abdominal pain was admitted to our hospital.Preoperative examinations revealed locally advanced squamous cell carcinoma (SCC) of the middle thoracic esophagus (T3N0M0 Stage ⅡA) and mucosal signetring cell carcinoma of the gastric antrum (T1N0M0 Stage ⅠA).Although the gastric tumor appeared to be an intramucosal carcinoma,its margin was obscure,so endoscopic en-bloc resection was considered inadequate.We chose surgical resection of the gastric tumor as well as the esophageal SCC after neoadjuvant chemotherapy with 5-fluorouracil and cisplatin for advanced esophageal cancer.Following transthoracic esophagectomy with three-field lymph node dissection,the gastric carcinoma was removed by gastric antrectomy,which preserved the right gastroepiploic vessels,and a pedunculated short gastric tube was used as the esophageal substitute.Twenty-eight months after the surgery,the patient is well with no evidence of cancer recurrence.Because it minimizes surgical stress and organ sacrifice,gastric tube interposition is a potentially useful technique for esophageal cancer associated with localized early gastric cancer.     

One-stage surgery for esophageal cancer.

Of 102 patients operated on from 1985 to 1989, 75 patients had esophageal cancer, 21 had cancer of the cardia involving the thoracic portion of the esophagus, 3 had gastroesophageal cancer, 2 had leiomyosarcoma, and 1 had an epidermoid lesion of the middle third of the esophagus and cardial adenocarcinoma. All of them underwent extirpation of the esophagus with one-stage esophagoplasty and the establishment of a cervical anastomosis. The esophagus was replaced by an isoperistaltic tube made from the greater curvature of the stomach in 95 patients, from the colon in 4, and from the small intestine in 3 patients. The abdominocervical approach was employed in 86 patients and with additional right-side thoracotomy in 16 patients. The gastric graft was formed using a laser scalpel and suture instruments. Postoperative mortality was 4.9% (i.e., 5 deaths). A number of surgical approaches through the abdomen are suggested, permitting visual exposure of the esophagus up to the aortic arch.     

Early gastric cancer: Report of 58 cases

Background. This retrospective study was carried out to review our surgical experience and to define the clinicopathologic profile of early gastric cancer in a Western country with one of the highest incidences in the world. Methods. Fifty-eight patients who had gastric surgery for early gastric cancer were included in this study. Results. The incidence of early gastric cancer was 13.9% of the patients with resected gastric cancer (58/416). The mean age of these 58 patients at diagnosis was 56.8 ± 12.3 years (range, 30–81 years) and the male: female ratio was 2.4 : 1. The most common presenting symptom was epigastric pain (52.4%). All patients were treated by surgical resection. Tumors were typically located in the antrum (72.4%), with a predominance of lesser curvature lesions (89.7%). Macroscopically, the majority of the lesions (63.8%) were excavated (types IIc and III). Thirty tumors were intramucosal and 28 extended into the submucosa. Thirty were of the intestinal type and 28 of the diffuse type. The rate of regional lymph node metastasis was 10.4%. The overall 5-year survival rate was 93.9%. Conclusions. The excellent response to surgical resection of early gastric cancer reported by Japanese authors is reproducible in Western countries even in the presence of regional lymph node metastasis. For this reason an aggressive surgical approach should be taken for all early gastric cancer. Received for publication on Jan. 20, 1998; accepted on Apr. 30, 1998     

Clinicopathological Characteristics of Synchronous Multiple Gastric Cancers in Chinese： An Analysis of 44 Cases

Objective: To investigate the clinicopathologic characteristics of the primary synchronous multiple gastric cancers (SMGC) in Chinese.Methods: Clinicopathologic data of patients with histologically confirmed gastric cancer who received surgical operations in our department between 1993 and 2002 were retrospectively collected and analyzed. Clinicopathologic characteristics including gender, age, tumor location, differentiation and staging between patients with SMGC and those with solitary gastric cancer (SGC) were compared. Synchronous multiple and solitary gastric cancers were diagnosed and classified based on radiography upper endoscopy and histology. All the cases were followed up after the operation and 5-year survival rate between the two groups was compared.Results: A total of 871 patients with gastric cancer were included. Synchronous multiple gastric cancers were found in 44 (5.1%) of these cases. More of the diagnose in the early stage to SMGC than to SGC. SMGC were more likely to be located at the lower third stomach and of a low grade differentiation, compared to SGC. However, there were no significant differences in the rates of lymph node metastasis and lymphatic vessel invasion between multiple and solitary gastric cancers. In addition, the 5-year survival rate did not difference between the two groups.Conclusion: The whole stomach should be detected carefully to avoid missing out the multiple gastric cancers. Concerning the treatment of multiple gastric cancer, the sufficient extent of the stomach wall resection was necessary, and the extent of lymphadenectomy was supposed to follow the operation for the solitary gastric cancer according to the staging of the cancer lesions.     

Comparison of the Anatomic Distribution of Stomach Cancer and Precancerous Gastric Lesions

The anatomic distribution of precancerous gastric lesions among 3,400 residents in Linqu, Shandong Province of China, was compared with the anatomic distribution of stomach cancer (SC) among 959 patients in Tokyo, Japan. The incidence of SC is high in both areas, and locations within the stomach of the precancerous and malignant lesions were classified using similar criteria. Chronic atrophic gastritis (CAG) affected 98% of the population in Linqu, with intestinal metaplasia (IM) the most severe diagnosis in 33% and dysplasia (DYS) in 20%. Neither the SC nor precancerous lesions were uniformly distributed in the stomach. Among the DYS 3% were along the greater curvature of the body, 15% along the lesser curvature of the body, 25% in the angulus, 22% along the lesser curvature of the antrum, and 34% elsewhere in the antrum. Among the SC the corresponding percentages were 2, 16, 28, 25 and 29. The similarity to the SC distribution increased gradually from CAG to IM to DYS, providing further evidence for the multistage progression of precancerous gastric lesions.     

Microsatellite instability in patients with gastric remnant cancer

Background. About 2% of patients who undergo partial distal gastrectomy for gastroduodenal diseases develop gastric remnant cancer 10 to 30 years after the gastrectomy. It is important in clinical practice to determine a molecular marker to identify patients susceptible to gastric remnant cancer. Methods. We investigated nine gastric remnant cancers (from nine individuals who had gastrectomies for primary gastric cancer or gastroduodenal ulcer) for microsatellite instability (MSI) at six loci, using the polymerase chain reaction (PCR). A control group of ten patients with sporadic gastric cancers in the upper third of the stomach was also similarly analyzed. Results. MSI was demonstrated in eight of nine cancers from the individuals who had had primary gastric cancer or gastroduodenal ulcer (88.9%) compared with two of ten cancers from the individuals with sporadic gastric cancer in the upper third of the stomach (20%). Conclusion. These results suggest that one or more MSI is associated with remnant gastric cancer after gastrectomy. Received on Sept. 6, 1999; accepted on Dec. 20, 1999     

Subtotal gastrectomy for gastric tube cancer after esophagectomy: a safe procedure preserving the proximal part of gastric tube based on intraoperative ICG blood flow evaluation

Recent improvements in the survival of patients after esophagectomy have led to an increase in the occurrence of gastric tube cancer (GTC). Total resection of the gastric tube with lymphadenectomy is a standard and reliable treatment for GTC, but problems may arise during or after surgery, such as laryngeal nerve injury, reduced selection of organs for reconstruction, and impaired swallowing function. We recently performed a less invasive procedure, subtotal gastrectomy with preservation of the upper region of the gastric tube, in two patients. In these patients, blood supply to the gastric tube was evaluated by indocyanine green fluorescence imaging. Blood flow was confirmed as passing from the remnant esophagus to the upper region of the gastric tube through the esophago-gastric anastomotic site by indocyanine green fluorescence imaging. Therefore, we resected the gastric tube while preserving the upper region of the gastric tube. There was no necrosis of the remnant gastric tube or anastomotic leakage postoperatively, and postoperative swallowing and eating functions were quite good in both patients. In summary, subtotal gastrectomy as a treatment for GTC is potentially safe, curative, and beneficial for the patient's quality of life.

A Prospective Study of Atrophic Gastritis and Stomach Cancer Risk

The relation of atrophic gastritis, other gastric lesions and lifestyle factors to stomach cancer risk was prospectively studied among 3,914 subjects who underwent gastroscopic examination and responded to a questionnaire survey at the Aichi Cancer Center Hospital. During 4.4 years of follow-up on average, 45 incident cases of stomach cancer were identified at least three months after the initial examination. If the baseline endoscopic findings indicated the presence of atrophic gastritis, the risk of developing stomach cancer was increased 5.73-fold, compared with no indication at the baseline. The risk further increased with advancing degree of atrophy and increasing extension of atrophy on the lesser curvature. These trends in the relative risks were statistically significant ( P = 0.027 and P = 0.041, respectively). The risk of developing stomach cancer was statistically significantly increased among subjects with gastric polyps, but not among those with gastric ulcer. Stomach cancer cases tended to consume more cigarettes, alcohol, rice, pickles and salted fish gut/cod roe and less fruits and vegetables and to have more family histories of stomach cancer than noncases, although these differences were not statistically significant. The results of the present study provide additional evidence on the relation between atrophic gastritis and stomach cancer and suggest a need for intensive follow-up of patients with atrophic gastritis and gastric polyps.
