Abstract PDF

Heterotopic gastric mucosa occurs in all areas of the gastrointestinal tract including the nasopharynx, tongue, esophagus, small intestine, colon, and rectum. Gastric heterotopia of the large bowel is infrequent, and most cases have been reported in the rectum. Review of the literature has revealed only eight cases involving the colon proximal to the rectum. Little is known of the natural history of gastric heterotopias, except that. It usually presents with gastrointestinal bleeding, though other serious complications such as bowel perforation, intussusceptions, and fistula formation, are possible. Further, it is unclear whether heterotopic gastric mucosa progresses to malignancy. Herein, we describe a case of adenocarcinoma of the transverse colon arising from gastric heterotopia. To the best of our knowledge, this is the first report of adenocarcinoma arising from heterotopic gastric mucosa in the colon.

Abstract PDF

BACKGROUND
Molecular tools for tissue profiling generally require collection of fresh frozen tissues (FFT) as sources of high-quality DNA and RNA. Nowadays, researchers carry out large-scale, multi-center studies and they request inter-institutional minimal intrinsic bias, some fundamental similarities, and the same standardized and validated procedures.
METHODS
This study reports standardized quality control procedure for fresh frozen tissue of the National Biobank of Korea.
RESULTS
The main procedures for quality control for FFT are as follows: records related to sample collection such as labeling of samples, transport temperature, lag time from excision of tissue to freezing, and sample size were reviewed for all fresh frozen samples. The stability of RNA and DNA in fresh frozen tissue was evaluated for 3% of collected samples and purity was assessed (ratio of the absorbance at 260 and 280 nm) as was integrity (agarose gel electrophoresis). Stained hematoxylin and eosin sections were reviewed by a pathologist to confirm the diagnosis and to assess how representative the frozen sample was.
CONCLUSIONS
We introduced that the quality-control criteria for fresh frozen tissue of the NBK. We expect that this study contributes to standardization of collection, storage, and quality control of fresh frozen tissue.

Abstract PDF

BACKGROUND
Regulatory T cells (Tregs) are known to be key regulators of immune responses in patients with autoimmune disease and infection and also for attenuating antitumor immunity by the host. It has been reported that high numbers of tumor-infiltrating Tregs might be associated with poor clinical outcomes for several malignant tumors. Therefore, this study aimed to examine the impact of tumor-infiltrating Tregs on the prognosis of gastric carcinoma patients.
METHODS
The immunohistochemical staining for anti-fork head Box P3 (FoxP3) antibody was performed by using a 3 mm core from the tumor specimens of each of the 173 gastric cancer patients for constructing a tissue microarray. FoxP3-positive Tregs were quantified by calculating the numbers of positive cells per 5 high-power fields on light microscopy. Thereafter, the 173 patients were subdivided into the low Tregs group (< or = 3/5 high power fields [HPF], n = 41) and the high Tregs group (> 3/5 HPF, n = 132).
RESULTS
The high Tregs group was significantly associated with a higher stage, more invasion depth and lymph node metastasis (p = 0.009, p = 0.036, p = 0.006, respectively). The high Tregs group showed significantly poorer overall survival and event-free survival (p = 0.004, p = 0.017, respectively) on the univariate analysis. The Tregs group and the tumor, node and metastasis stage were also independent prognostic factors that were significantly associated with overall survival (p = 0.025, p < 0.001, respectively) by multivariate analysis.
CONCLUSIONS
Our results indicated that a high number of tumor-infiltrating FoxP3-positive Tregs could be an indicator of poor long term survival for gastric carcinoma patients.

Abstract PDF

BACKGROUND
Serum response factor (SRF) is a transcriptional factor that plays an important role in cell growth and differentiation for several types of cells. The expression of SRF in cholangiocarcinoma (CC) and its potential role has not been examined. The aim of this study was to determine the relationship between the expression of SRF in CC and the clinicopathological parameters, as well as patient survival.
METHODS
We analyzed the expression of SRF in 84 surgically resected cases of CC (33 cases of intrahepatic CC [ICC] and 51 cases of extrahepatic CC [ECC]) by using immunohistochemistry. RESULTS: The positive expression of SRF was detected in 48.8% of the cases of CC (42.4% in ICC, 52.9% in ECC). SRF was predominantly expressed in the CC cells with intense labeling in the nucleus. A SRF expression was significantly associated with the cell proliferation rate (Ki-67 labeling index, p=0.046) and poor patient survival (p=0.002). The tumor differentiation (p=0.038), the T category (p<0.001), lymph node and distant metastasis (p<0.001, p=0.009) and nerve and vessel invasion (p=0.010, p=0.012) were also found to be significantly associated with a poor CC prognosis. CONCLUSIONS: These results suggest that the SRF may play a role in the tumor cell proliferation of CC, and its expression in tumor cells can provide additional prognostic information.
