Background
S100A8 and S100A9 have been gaining recognition for modulating tumor growthand metastasis. This study aimed at evaluating the clinical significance of S100A8 and S100A9 innon-small cell lung cancer (NSCLC).
Methods
We analyzed the relationship between S100A8and S100A9 expressions, clinicopathological characteristics, and prognostic significance in tumorcells and peritumoral inflammatory cells.
Results
The positive staining of S100A8 in tumorcells was significantly increased in male (p < .001), smoker (p = .034), surgical method other thanlobectomy (p = .024), squamous cell carcinoma (SQCC) (p < .001) and higher TNM stage (p = .022)compared with female, non-smoker, lobectomy, adenocarcinoma (ADC), and lower stage. Theproportion of tumor cells stained for S100A8 was related to histologic type (p < .001) and patientsex (p = .027). The proportion of inflammatory cells stained for S100A8 was correlated with patientage (p = .022), whereas the proportion of inflammatory cells stained for S100A9 was correlatedwith patient sex (p < .001) and smoking history (p = .031). Moreover, positive staining in tumorcells, more than 50% of the tumor cells stained and less than 30% of the inflammatory cellsstained for S100A8 and S100A9 suggested a tendency towards increased survivability in SQCCbut towards decreased survivability in ADC.
Conclusions
S100A8 and S100A9 expressions might be potential prognostic markers in patients with NSCLC.

Abstract PDF

Background
For endometrioid carcinoma patients, International Federation of Gynecologists and Obstetricians (FIGO) histologic grading is very important for identifying the appropriate treatment method. However, the interobserver discrepancy with this three-tiered grading system is a serious potential problem. In this study, we used immunohistochemistry to analyze the relationship between FIGO histologic grading score and myoferlin expression.
Methods
We studied the endometrioid carcinoma tissues of 60 patients from Gyeongsang National University Hospital between January 2002 and December 2009. Immunohistochemical analysis of myoferlin was performed on tissue microarray blocks from surgical specimens.
Results
Myoferlin expression was observed in 58 of 60 patients. Moderate and strong myoferlin expression was observed in low-grade endometrioid carcinoma, while there was a tendency toward loss of myoferlin expression in high-grade endometrioid carcinoma (p<.001).
Conclusions
Our study revealed that myoferlin loss is significantly correlated with high FIGO grade of endometrioid carcinoma.

Abstract PDF

Background

Epithelial-mesenchymal transition (EMT) is associated with tumor hypoxia. EMT is regulated, in part, by the action of TWIST, which inhibits of E-cadherin expression and may interfere with the p53 tumor-suppressor pathway.

Methods

We examined the expression of TWIST, E-cadherin, hypoxia-inducible factor 1α (HIF1α), and p53 by immunohistochemistry in 123 cases of ovarian epithelial cancers (OEC) to evaluate the role of TWIST in OEC. We assessed the association between protein expression and clinicopathologic parameters.

Results

The expression of TWIST, E-cadherin, HIF1α, and p53 proteins was found in 28.5%, 51.2%, 35.0%, and 29.3% of cases, respectively. TWIST expression was associated with higher histologic grade and unfavorable survival. TWIST expression was correlated with HIF1α expression and reduced E-cadherin expression. The altered HIF1α/TWIST/E-cadherin pathway was associated with lower overall survival (OS), while the co-expression of TWIST and p53 was correlated with lower progression-free survival. In the multivariate analyses, TWIST expression was an independent prognostic factor for OS.

Conclusions

Our data imply that TWIST expression could be a useful predictor of unfavorable prognosis for OEC. TWIST may affect the p53 tumor-suppressor pathway. Moreover, hypoxia-mediated EMT, which involves the HIF1α/TWIST/E-cadherin pathway may play an important role in the progression of OEC.

Abstract PDF

Background

Tumor hypoxia is associated with malignant progression and treatment resistance. Hypoxia-related factors, such as carbonic anhydrase IX (CA IX), glucose transporter-1 (GLUT-1), and vascular endothelial growth factor (VEGF) permit tumor cell adaptation to hypoxia. We attempted to elucidate the correlation of these markers with variable clinicopathological factors and overall prognosis.

Methods

Immunohistochemistry for CA IX, GLUT-1, and VEGF was performed on formalin-fixed, paraffin-embedded tissues from 125 cases of ovarian epithelial cancer (OEC).

Results

CA IX expression was significantly associated with an endometrioid and mucinous histology, nuclear grade, tumor necrosis, and mitosis. GLUT-1 expression was associated with tumor necrosis and mitosis. VEGF expression was correlated only with disease recurrence. Expression of each marker was not significant in terms of overall survival in OECs; however, there was a significant correlation between poor overall survival rate and high coexpression of these markers.

Conclusions

The present study suggests that it is questionable whether CA IX, GLUT-1, or VEGF can be used alone as independent prognostic factors in OECs. Using at least two markers helps to predict patient outcomes in total OECs. Moreover, the inhibition of two target gene combinations might prove to be a novel anticancer therapy.

Abstract PDF

The giant cell tumor of the salivary gland is very rare, and 20 cases have been reported in the English-language literature. We report an additional case. A 57-year old man had noticed a mass in the right parotid area for several weeks. The diagnosis using aspiration cytology was a giant cell tumor possibly with a carcinomatous component. Superficial parotidectomy was carried out. The resected parotid gland contained a 1.8 cm-sized well-circumscribed brownish tumor. Histologically the tumor consisted of evenly distributed osteoclast-like giant cells, mononuclear cells and two small foci of a carcinomatous component. The osteoclast-like giant cells and mononuclear cells were positive for vimentin and CD68, and the carcinomatous component was positive for cytokeratin and epithelial membrane antigen. There was no metastatic lesion in the cervical lymph nodes. We believe this is the first case in Korea of an osteoclast-like giant cell tumor of the parotid gland.

Abstract PDF

BACKGROUND
Recent studies have demonstrated that insulin-like growth factor II mRNA-binding protein 3 (IMP3) is expressed in malignant tumors of various organs but not in normal tissue. We investigated IMP3 expression in various benign lesions, premalignant lesions and carcinomas of the stomach.
METHODS
IMP3 immunohistochemical staining was performed on 24 benign gastric lesions, 24 gastric adenomas, and 322 gastric carcinomas.
RESULTS
IMP3 was not expressed in benign gastric lesions including adenomas with low-grade dysplasia, but was expressed in 17% of adenomas with high-grade dysplasia, and in 44% of carcinomas. As the carcinomas were in the advanced stage, they expressed IMP3 more frequently and strongly. Patients with IMP3-positive tumors had poorer survival than those with negative tumors.
CONCLUSIONS
IMP3 expression in gastric carcinoma may be related to tumor invasion and metastasis, and is an independent risk factor for poor prognosis.

Abstract PDF

BACKGROUND
Pathologists occasionally have difficulty in distinguishing cholangiocarcinoma from benign reactive cells on the biliary cytology. We estimated the diagnostic value of insulinlike growth factor II mRNA binding protein 3 (IMP3) on biliary cytology specimens.
METHODS
We selected 40 patients who had undergone a biliary cytology examination and whose diagnoses were confirmed by biopsy. The IMP3 expression was evaluated by immunohistochemical staining in both the tissue and the cytology specimens. Their histologic diagnoses were cholangiocarcinoma (n = 34), high grade dysplasia (n = 2), low grade dysplasia (n = 1) and non-biliary tumor or no tumor (n = 3).
RESULTS
On the histology, all the cases of cholangiocarcinoma or high grade dysplasia were positive for IMP3 (36/36). The low grade dysplasia or the normal bile ducts in the other 4 cases were negative for IMP3 (0/4). Of the 36 cases diagnosed as cholangiocarcinoma or high grade dysplasia histologically, 29 cases were positive for IMP3 on the cytology (29/36; sensitivity, 80.6%). Of the 4 cases without cholangiocarcinoma or high grade dysplasia, 1 case was weakly positive for IMP3 on the cytology. The histologic diagnosis of this case was hepatocellular carcinoma. Except for this hepatocellular carcinoma case, the specificity of IMP3 on the cytology was 100%.
CONCLUSIONS
IMP3 is a useful diagnostic marker for cholangiocarcinoma on cytology.

Abstract PDF: A microscopic examination of 1,000 cases of gastroscopic biopsy specimens revealed that the prevalence and severity of chronic gastritis, neutrophilic infiltration, and Helicobacter pylori infection increased with advancing age until the age reached about 40, but they decreased thereafter in accordance with the increasing prevalence of intestinal metaplasia. The prevalence and severity of Helicobacter pylori infection, chronic gastritis, and neutrophilic infiltration were proportionately related to each other and to gastric peptic ulcer, but inversely related with intestinal metaplasia and gastric carcinoma. The results suggested that chronic gastritis and gastric peptic ulcer may be associated with Helicobacter pylori infection and that if these lesions persist, intestinal metaplasia may develop with decreased severity of chronic gastritis and Helicobacter pylori infection but, instead, increase of the risk of gastric carcinoma. And it is thought that the cause of the high incidence of gastric carcinoma in Korea may be related to the fact that chronic gastritis and Helicobacter pylori infection develop earlier in life and therefore the prevalence of intestinal metaplasia is higher in Korea than in other countries.

Abstract PDF: BACKGROUND
Helicobacter pylori is present mainly in the gastric mucous layer. However, the mucous layer, along with the bacteria, is lost during conventional tissue processing in which formalin is used for fixation. The purpose of this study is to ascertain - if the mucous layer is preserved by using Carnoy solution as a fixative - whether the detection rate of H. pylori is increased in pediatric patients.
METHODS
Five pieces of gastric mucosal tissue were obtained from the gastric antrum and the body of one hundred pediatric patients. One of the specimens was fixed with formalin. Another specimen was fixed with Carnoy solution. The tissue sections were stained with hematoxylin-eosin and immunohistochemically stained for H. pylori. For reference, a rapid urease test was performed on the remaining three specimens.
RESULTS
In the formalin-fixed tissue, the detection rate of H. pylori was 13% in the gastric antrum and 12% in the body (overall 16%). In the Carnoy solution-fixed tissue, the mucous layer was preserved and the detection rate of H. pylori was 23% in the antrum and 27% in the body (overall 28%). The positive rate of the rapid urease test was 26% in the antrum and 28% in the body (overall 29%).
CONCLUSIONS
When the number of H. pylori is small in the gastric mucosa, the bacteria may not be detected by conventional histologic methods. In that case, the detection rate of H. pylori may be increased by using Carnoy solution, rather than formalin, as a tissue fixative.

Abstract PDF: BACKGROUND
It has been believed that there is a pure mucus-secreting cardiac mucosa (CM), about 2 cm in length, below the gastroesophageal junction. However, recent reports suggest that CM might not be located at the most proximal portion of the stomach. The purpose of this study is to investigate the relationships between the types of proximal gastric mucosa and patients' age, sex, their condition regarding the Helicobacter pylori infection, and severity of chronic gastritis.
METHODS
Two pieces of mucosal tissue from the most proximal portion of the stomach and the antrum of 44 pediatric and 85 adult patients were examined using a light microscope. A rapid urease test was performed on the other antral specimen from each patient.
RESULTS
In 46 (90.2%) out of 51 patients with aged 30 or under, only the pure acid-secreting oxyntic mucosa (OM) was present at the most proximal portion of the stomach. The cardiac or mixed oxyntocardiac mucosa (OCM) increased in prevalence with age. The CM or OCM was found more frequently in patients with H. pylori infection or severe gastritis than in those without H. pylori infection or those with mild gastritis. However, there were no statistically significant differences within the same age groups.
CONCLUSIONS
Although the OCM is sometimes present at the most proximal portion of the stomach, the CM is absent or rare in individuals under the age of 30. The OCM or CM increases in prevalence with age. There are no direct relationships between the type of proximal gastric mucosa and a patient's gender, his/her condition regarding the H. pylori infection, and severity of chronic gastritis.

Abstract PDF: It was reported that the main cause of intraepithelial neoplasm and squamous cell carcinoma of the uterine cervix is human papilloma virus infection, and that the expression of p16 is increased in cells infected by human papilloma virus. We performed an immunocytochemical staining for protein p16 in 17 cases of cervocovaginal smears initially diagnosed as atypical squamous cells of undetermined significance, to know whether the staining could help the differentiation of neoplastic cells from reactive atypical cells. Of 17 smears, 6 were diagnosed finally as high grade intraepithelial neoplasm or invasive squamous cell carcinoma by follow-up biopsy and smear, and 5 of the 6 were positive for p16. Three were diagnosed as koilocytosis, and one of them was weakly positive for p16. Eight were diagnosed as reactive atypical cells, and all of them were negative for p16. We thought that immunocytochemical staining of p16 in cervocovaginal smears could help the differentiation of neoplastic cells from reactive atypical cells.

Abstract PDF: BACKGROUND
Gastric metaplasia of the duodenum is thought to be associated with the pathogenesis of duodenal ulcer. We investigated the pathological features of gastric metaplasia and their relation to age, gender, duodenal ulcer and H. pylori infection.
METHODS
We reviewed the duodenal endoscopic findings of 535 patients (age range: 0 to 87) and the microscopic slides of the duodenal biopsy specimens.
RESULTS
Gastric metaplasia was first noted at the age of 4 and the prevalence increased thereafter until the patients' mean age reached about 30. The prevalence of gastric metaplasia was 53.7% after 30 years of age. As the metaplasia became severer, it became more polypoid in appearance and it more often contained parietal cells. Gastric metaplasia was more frequently observed or severe in duodenal ulcer patients, in males and in the first portion of the duodenum than in patients without duodenal ulcer, in females and in the second portion, respectively. There was a lack of correlation between gastric metaplasia and H. pylori infection.
CONCLUSIONS
The prevalence and/or severity of gastric metaplasia of the duodenum increases with age, and it is thought that most duodenal ulcers develop in the areas of gastric metaplasia.

Abstract PDF: BACKGROUND
Prior studies of p16, p53, and Ki-67 expression have suggested that these markers may be preferentially expressed in cervical neoplasms. The purpose of this study was to assess the expression and clinical significance of p16, p53 proteins, and the Ki-67 labeling index in the cervical lesions.
METHODS
We analyzed 54 uterine cervical specimens obtained by surgical biopsy. The expression of p16, p53 proteins, and Ki-67 was evaluated by immunohistochemical methods. The immunohistochemical findings were then correlated with the histologic diagnosis.
RESULTS
Positive scores for p16, p53, and Ki-67 were seen in 75% (6/8), 0% (0/8), and 13% (1/8) of low grade intraepithelial lesions (LSIL), respectively, and 100% (23/23), 17% (4/23), and 74% (17/23) of high grade intraepithelial lesions (HSIL), respectively, and 100% (10/10), 20% (2/10), and 70% (7/10) of invasive squamous cell carcinomas, respectively. Both normal epithelium and inflammatory lesions scored negative for these three markers in all of the 13 cases. p16 and Ki-67 expression correlated with the severity of uterine cervix lesions.
CONCLUSIONS
p16 and Ki-67 are complementary surrogate biomarkers for cervical squamous intraepithelial neoplasia. However, immunohistochemical expression for p53 has no correlation with the grade of cervical squamous intraepithelial neoplasia.
