Abstract

Abstract Background Both endoscopic and surgical approaches are employed in the treatment of early gastric cancer (EGC). The aim of this study was to establish appropriate treatment strategies for early gastric cancer. Methods We retrospectively examined clinicopathological data of EGC patients who had undergone surgery. Results A total of 327 patients (204 males and 123 females, mean age 63.2 years) were eligible for inclusion in the study. The median follow-up period was 31 months. Of 161 mucosal (pT1a) tumors, 87 were mainly undifferentiated and 110 had an undifferentiated component. Four patients with pT1a tumors had lymph node metastases; all these tumors were signet-ring cell carcinomas and were macroscopic type 0-IIc with ulceration, and only one of them had lymphatic invasion. Among patients with submucosal tumors, four of 43 patients with pT1b1 tumors and 37 of 123 patients with pT1b2 tumors had nodal metastases. Lymph node metastases were significantly higher in mixed undifferentiated type group than differentiated type group for both groups, pT1a-pT1b1 (p = 0.0251) and pT1b2 (p = 0.0430) subgroups. Only four of 45 patients with nodal metastases were diagnosed preoperatively by computed tomography (sensitivity 8.9%, specificity 96.2%). Nine patients with pT1b tumors had recurrence after surgery, and died. The sites of initial recurrence were liver, bone, peritoneum, distant nodes, and the surgical anastomosis. Conclusions The incidence of nodal metastases was approximately 5% in undifferentiated type mucosal (pT1a) tumors, and higher in submucosal (pT1b) tumors. The sensitivity of preoperative diagnosis of nodal metastases in EGC using computed tomography was relatively low in this study. Therefore at present surgery with adequate lymphadenectomy should be performed as curative treatment for undifferentiated type EGC.

Abstract

There have been many reports on the overexpression of human epidermal growth factor receptor 2 (HER2) in patients with colon cancer. However, the role and frequency of HER2 overexpression have not been clearly defined. Anti-HER2 therapy has been shown to improve the prognosis of HER2-positive patients with breast and stomach cancers. In this study, we explored HER2 expression in patients with colon cancer at stages II and III by immunohistochemistry (IHC) and dual-color in situ hybridization (DISH), and examined the correlation between HER2 expression and clinicopathological factors. Moreover, we examined the correlation between HER2 expression and mucin 1 (MUC1) expression. The subjects were 121 patients with colon cancer at stages II and III who underwent surgery in our hospital during the period from 2007 to 2009. Sections containing the deepest part of a lesion were subjected to immunostaining for HER2 and MUC1. HER2 expression was assessed in accordance with Ventana's Guidelines for HER2 Testing in Stomach Cancer, with sections comprising less than 10% of weakly to moderately stained tumor cells scored as 1 > 2. HER2 expression scored as 2 was defined with sections comprising more than 10% of the weakly to moderately stained tumor cells. Patients with a score of 1 > 2 and 2 were also subjected to DISH using a Dual ISH HER2 kit. MUC1 expression was scored according to the percentage of stained area as follows: 0, 0 to 5%; 1, 5 to 50%; and 2, 50% and higher. Patients with a score of 1 and 2 were defined as MUC1-positive. The analysis of HER2 by IHC yielded the following scores: 45 patients (37.2%), 0; 38 patients (31.4%), 1; 14 patients (11.6%); 1 > 2; 24 patients (19.8%), 2; and 0 patients (0%), 3. For the 38 patients with a score of 1 > 2 and 2, DISH returned ratios of HER2 to Chr17 expression (HER2: Chr17 ratio) from 1.13 to 1.93 (mean = 1.46). There was no significant correlation between HER2 expression and clinicopathological factors. The numbers of MUC1-positive patients according to HER2 score were as follows: 22 patients (48.9%) in the score 0 group (45 patients); 25 patients (65.8%) in the score 1 group (38 patients); 10 patients (71.4%) in the score 1 > 2 group (14 patients), and 22 patients (91.7%) in the score 2 group (24 patients). There was a positive correlation between HER2 expression and MUC1 expression. Specifically, MUC1 expression levels increased with HER2 expression level, and the percentage of MUC1-positive patients was significantly higher in the HER2 score 2 group than in the HER2 score 0 group (P < 0.01). Rates of HER2 positivity by DISH or fluorescence in situ hybridization (FISH) in patients who had an HER2 score of 2+ by IHC were 45% and 24% in the patients with stomach and breast cancers, respectively. However, the positivity rate was 0% in the patients with colon cancer in this study. This result indicates that patients with colon cancer who have an IHC HER2 score of 2+ are more likely to be HER2 negative by DISH than patients with breast and stomach cancers, although larger cohort studies are required before a definitive conclusion can be made. There was a positive correlation between HER2 expression and MUC1 expression in this study, although further examination is required because there were no patients who had an HER2 score of 3+ or 2+ by IHC and were HER2 positive by DISH in this study. HER2 expression in colon cancer should be cautiously assessed by both IHC and DISH.

Abstract

A 38-year-old man with a submucosal tumor (SMT) at the anterior wall of the pylorus underwent upper gastrointestinal endoscopy. The tumor was 40 mm in diameter with a long stalk extending into the duodenal bulb. In addition, the long stalk had an ulcer with a blood vessel. Removal of this tumor was initially considered to be possible only by distal gastrectomy. However, endoscopic ultrasound (EUS) was subsequently proven to be a reliable investigative procedure for evaluating the lesion. The tumor was characterized by its origin in the second layer, and endoscopic submucosal dissection (ESD) was performed. En bloc resection of a 32 × 20 × 40 mm area of tissue with tumor-free lateral/vertical margins was accomplished without complication. Histopathological examination confirmed a heterotopic gastric mucosa. By immunostaining, the neoplasm was positive for MUC6 and negative for amylase and trypsin. In this case, EUS was used to investigate a heterotopic gastric mucosa that originated in the second layer, with no infiltration of the fourth layer under the tumor. Therefore, we performed successful ESD at the appropriate layer.

Abstract

We report here a case of peripheral primitive neuroectodermal tumor (PNET) arising from the minor salivary gland. A 22-year-old woman was admitted to our hospital for surgical excision of a small painless cheek tumor with a 7-month history. Macroscopically, the tumor measured 10 × 5 × 6mm and was located in the minor salivary gland. Microscopically, the tumor comprised proliferating, small, round cells with scant cytoplasm and high nuclear cytoplasmic ratios. The tumor cells showed some mitotic figures and Homer-Wright-type rosettes. Immunohistochemically, the tumor cells were immunopositive for CD99, synaptophysin, CD56, S-100 protein, and vimentin. Based on these findings, the patient was diagnosed as having PNET arising from the minor salivary gland. There are very few case reports of PNET in the head and neck region, and to the best of our knowledge, this is the first case report of PNET arising from the minor salivary gland.

Abstract

A rare autopsy case of multiple jejunal diverticula showing severe malabsorption is reported. A 56-year-old man was admitted due to vomiting and leg edema. On admission, his height was 160cm, his body weight was 39kg, and laboratory data revealed severe hypoproteinemia (TP: 4.0g/dl, ALB: 2.1g/dl). On the 14th day of admission, agonal breathing and disturbance of consciousness occurred after massive vomiting of gastric juice, and the patient died of respiratory failure. At autopsy, on abdominal sectioning, multiple diverticula situated on the mesenterium side of the enteron extending 70cm in length from the proximal jejunum were identified. However there were no findings suggesting perforation or diverticulitis. Histologically, the diverticula were lined by ordinal jejunum mucosa associated with muscularis mucosa, but the muscularis propria was not involved in the diverticular walls. The diverticula were identified as false diverticula. In both lower lungs, aspiration pneumonia was widely seen. The cause of death was considered to be aspiration pneumonia due to the vomiting caused by multiple jejunal diverticula.Only 16 case reports of multiple jejunal diverticulosis in Japan could be found in the literature however most of the reported complications were perforation and diverticulitis, and there were no reports of malabsorption. Therefore, the present case is significant concerning the cause of malabsorption in routine explorations.

Abstract

Herein, we report on an unusual case of polypoid mixed hemangioma of the sigmoid colon. An 85-year-old woman who underwent colonoscopic examination was found to have a smooth, red polypoid tumor, 6mm in diameter, in the sigmoid colon. The polyp was resected endoscopically. Microscopically, the polyp contained two pathologic components: (i) adenomatous proliferative glands as the epithelial component; and (ii) mixed hemangioma as the mesenchymal component. On the basis of these findings, a pathological diagnosis of angioadenomatous polyp was made. Although seven previous cases of polypoid hemangioma located in the submucosa have been reported in the literature, the present case is the first in which the hemangioma is localized only in the mucosa. The mixed hemangioma may be the pathogen stimulating the adenomatous proliferation of the glands.

Abstract

The aim of this retrospective study was to evaluate L-type amino acid transporter 1 (LAT1) expression in colorectal cancer with invasion to the subserosal layer (T3), its relationship with clinicopathological characteristics, and its potential metastatic significance. LAT1 expression was measured by immunohistochemistry in tumors from 65 patients with primary colorectal carcinomas. LAT1 expression was deemed positive when more than 10% of the tumor cells showed distinct membranous immunoreactivity. Positive LAT1 expression was demonstrated in 29.2% (19 of 65) of primary tumors. LAT1 expression showed no significant relationship with clinicopathological characteristics, such as age, gender, tumor location, tumor size, macroscopic/microscopic classification, or lymph node metastasis. However, LAT1 expression showed a positive relationship with liver metastasis (P < 0.05). LAT1 expression in cancer cells may be a good marker for predicting potential metastasis to the liver in colorectal cancer.
