Background
Exposure to cigarette smoking (CS) is a major risk factor for the development of lung cancer. CS is known to cause oxidative DNA damage and mutation of tumor-related genes, and these factors are involved in carcinogenesis. 8-Hydroxydeoxyguanosine (8-OHdG) is considered to be a reliable biomarker for oxidative DNA damage. Increased levels of 8-OHdG are associated with a number of pathological conditions, including cancer. There are no reports on the expression of 8-OHdG by immunohistochemistry in non-small cell lung cancer (NSCLC).
Methods
We investigated the expression of 8-OHdG and p53 in 203 NSCLC tissues using immunohistochemistry and correlated it with clinicopathological features including smoking.
Results
The expression of 8-OHdG was observed in 83.3% of NSCLC. It was significantly correlated with a low T category, negative lymph node status, never-smoker, and longer overall survival (p < .05) by univariate analysis. But multivariate analysis revealed that 8-OHdG was not an independent prognostic factor for overall survival in NSCLC patients. The aberrant expression of p53 significantly correlated with smoking, male, squamous cell carcinoma, and Ki-67 positivity (p < .05).
Conclusions
The expression of 8-OHdG was associated with good prognostic factors. It was positively correlated with never-smokers in NSCLC, suggesting that oxidative damage of DNA cannot be explained by smoking alone and may depend on complex control mechanisms.

Abstract PDF

Background
Increasing evidence has shown that tumor initiation and growth are nourished by a small subpopulation of cancer stem cells (CSCs) within the tumor mass. CSCs are posited to be responsible for tumor maintenance, growth, distant metastasis, and relapse after curative operation. We examined the expression of CSC markers in paraffin-embedded tissue sections of hepatocellular carcinoma (HCC) and correlated the results with clinicopathologic characteristics. Methods: Immunohistochemical staining for the markers believed to be expressed in the CSCs, including epithelial cell adhesion molecule (EpCAM), keratin 19 (K19), CD133, and CD56, was performed in 82 HCC specimens. Results: EpCAM expression was observed in 56% of the HCCs (46/82) and K19 in 6% (5/82). EpCAM expression in HCC significantly correlated with elevated α-fetoprotein level, microvessel invasion of tumor cells, and high histologic grade. In addition, Ep- CAM expression significantly correlated with K19 expression. The overall survival and relapsefree survival rates in patients with EpCAM-expressing HCC were relatively lower than those in patients with EpCAM-negative HCC. All but two of the 82 HCCs were negative for CD133 and CD56, respectively. Conclusions: Our results suggest that HCCs expressing EpCAM are associated with unfavorable prognostic factors and have a more aggressive clinical course than those not expressing EpCAM. Further, the expression of either CD133 or CD56 in paraffin-embedded HCC tissues appears to be rare.

Abstract PDF

Background

High-risk human papillomavirus (HR-HPV) infection and abnormal p53 expression are closely involved in carcinogenesis of squamous cell carcinoma (SqCC) of uterine cervix. Recent studies have suggested that virus-induced endoplasmic reticulum (ER) stress modulates various cell survival and cell death signaling pathways. The C/EBP homologous protein (CHOP) is associated with ER stress-mediated apoptosis and is also involved in carcinogenesis of several human cancers. We hypothesized that CHOP is involved in the carcinogenesis of uterine cervical cancer in association with HR-HPV and/or p53.

Methods

Immunohistochemistry was used to analyze CHOP and p53 protein expression of tissue sections from 191 patients with invasive cancer or preinvasive lesions of the uterine cervix (61 cases of SqCC, 66 cases of cervical intraepithelial neoplasia [CIN] III, and 64 cases of CIN I).

Results

CHOP was expressed in 59.4% of CIN I, 48.5% of CIN III, and 70.5% of SqCC cases. It was also significantly more frequent in invasive SqCC than in preinvasive lesions (p=0.042). Moreover, CHOP expression significantly correlated with HR-HPV infection and p53 expression (p=0.009 and p=0.038, respectively).

Conclusions

Our results suggest that CHOP is involved in the carcinogenesis of the uterine cervix SqCC via association with HR-HPV and p53.

Abstract PDF

Background

Cortactin and focal adhesion kinase (FAK) are two important components among actin cross-linking proteins that play a central role in cell migration.

Methods

The aims of this study were to evaluate the expression of cortactin and FAK in normal colorectal mucosa and colorectal adenocarcinoma (CRC) using tissue microarray of 2 mm cores to correlate their expression with other clinicopathological factors and, investigate their prognostic significance.

Results

Twenty (9%) and 24 cases (11%) of normal colorectal mucosa were immunoreactive for cortactin and FAK. In addition, 184 (84%) and 133 cases (61%) of CRCs were immunoreactive for cortactin and FAK, respectively. Cortactin expression was associated with histologic differentiation and FAK expression. Cortactin, but not FAK expression was also correlated with poor overall and relapse-free survival and served well as an independent prognostic factor for poor survival.

Conclusions

Cortactin expression, in association with FAK expression, may plays an important role in tumor progression. Furthermore, it may also be a satisfactory biomarker to predict tumor progression and survival in CRC patients.

Abstract PDF

Background

E-cadherin, cortactin, and matrix metalloproteinase (MMP)-9 have roles in tumor development or progression, but their expression has not been fully investigated in pseudoepitheliomatous hyperplasia (PEH) and squamous cell carcinoma (SCC) of the head and neck.

Methods

We evaluated the immunohistochemical expression of E-cadherin, cortactin, and MMP-9 in 29 cases of PEH and 97 cases of SCC. Additionally, we evaluated their relationship with clinicopathologic factors and prognostic implications in SCC.

Results

Thirty-five cases of SCC showed reduced expression of E-cadherin, whereas none of the PEH did. A total of 20 cases and 11 cases of SCC were immunoreactive for cortactin and MMP-9, respectively, whereas none of the PEH did. In SCC, reduced expression of E-cadherin was correlated with cortactin expression and invasion depth. Cortactin expression was correlated with differentiation, T classification, and recurrence and/or metastasis. MMP-9 expression was correlated with invasion depth. Cortactin expression was correlated with poor overall survival and relapse-free survival and it was an independent prognostic factor.

Conclusions

The reduced expression of E-cadherin and the expression of cortactin may be helpful for the differential diagnosis of PEH and SCC. Furthermore, cortactin expression in association with reduced E-cadherin expression is correlated with poor prognosis in SCC.

Abstract PDF: Metastases of malignant tumors to the oral region from distant sites are uncommon. A 45-year-old man with painless gingival swelling was diagnosed with adenocarcinoma of the lung. On cytology, clusters of tumor cells on mucous background revealed enlarged nuclei, indistinct cell borders, and irregular nuclear membranes. Some cells showed nuclear inclusions, nuclear grooves and small nucleoli. These findings are indicative of metastatic adenocarcinoma. We present a case of gingival metastasis from a lung adenocarcinoma.

Abstract PDF: In situ follicular lymphoma is a newly defined entity among the lymphoid neoplasms and is defined as architecturally normal-appearing lymph nodes and other lymphoid tissues that have one or more follicles that demonstrate bcl-2 overexpressing centrocytes and centroblasts, with or without a monomorphic cytologic appearance suggestive of follicular lymphoma. Here we present a case of in situ follicular lymphoma diagnosed during the follow-up after a complete response to the treatment of lymphocyte-rich classical Hodgkin's lymphoma. In our case, because only a few germinal centers contained bcl-2 overexpressing cells, we missed the diagnosis of in situ follicular lymphoma in the initial histological examination. We could establish the diagnosis only after performing bcl-2 immunostaining in the sequential biopsy. Therefore, we recommend that careful histological examination along with bcl-2 immunostaining is needed in patients with suspicious clinical findings.

Abstract PDF

BACKGROUND
The Korean Bone and Soft Tissue Pathology Study Group of the Korean Society of Pathologists conducted a nationwide retrospective analysis of soft tissue sarcoma (STS) to provide the clinicopathologic characteristics of STS within the population of the Republic of Korea.
METHODS
The cases of STS were collected during a 7-year period (2001-2007) from 19 institutes in Korea. All cases were classified according to the histologic criteria proposed by the World Health Organization. Clinicopathologic data were reviewed.
RESULTS
Data from 722 patients (median age, 50 years) were collected. Data showed a slight male predominance. The most frequent types of STS in decreasing order were liposarcoma, malignant fibrous histiocytoma, leiomyosarcoma, and synovial sarcoma. STS occurred throughout the body, although approximately half (47.8%) were located in the extremities. The majority of STS was histologically classified as high grade with a large tumor size (>5 cm). The overall survival rate for the patients was 76.3% (median follow-up time, 26 months; range, 1 to 89 months). Histologic grade, tumor size, American Joint Committee on Cancer stage, tumor site, and resection status were prognostic. Significant independent adverse prognostic factors were large tumor size (>5 cm) and tumor site other than extremities.
CONCLUSIONS
We reported the distribution and characteristics of STS in the Republic of Korea.

Abstract PDF

BACKGROUND
The aim of study was to determine the relative frequency of malignant lymphoma according to World Health Organization (WHO) classification in Korea.
METHODS
A total of 3,998 cases diagnosed at 31 institutes between 2005 and 2006 were enrolled. Information including age, gender, pathologic diagnosis, site of involvement and immunophenotypes were obtained.
RESULTS
The relative frequency of non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL) was 95.4% and 4.6%, respectively. B-cell lymphomas accounted for 77.6% of all NHL, while T/natural killer (T/NK)-cell lymphomas accounted for 22.4%. The most frequent subtypes of NHL were diffuse large B-cell lymphoma (42.7%), extranodal marginal zone B-cell lymphoma (MZBCL) of mucosa-associated lymphoid tissue (19.0%), NK/T-cell lymphoma (6.3%) and peripheral T-cell lymphoma (PTCL), unspecified (6.3%), in decreasing order. The relative frequency of HL was nodular sclerosis (47.4%), mixed cellularity (30.6%), and nodular lymphocyte predominant (12.1%) subtypes. Compared with a previous study in 1998, increase in gastric MZBCL and nodular sclerosis HL, and slight decrease of follicular lymphoma, PTCL, and NK/T-cell lymphoma were observed.
CONCLUSIONS
Korea had lower rates of HL and follicular lymphoma, and higher rates of extranodal NHL, extranodal MZBCL, and NK/T-cell lymphoma of nasal type compared with Western countries. Changes in the relative frequency of lymphoma subtypes are likely ascribed to refined diagnostic criteria and a change in national health care policy.

Abstract PDF

Glomus tumors of the stomach are rare and are usually found as a solitary, intramural lesion. Here, we report a case of a gastric glomus tumor in a 60-year-old woman diagnosed by endoscopic ultrasound-guided fine-needle aspiration cytology. Endoscopic ultrasound revealed a 4 x 3 cm-sized, round, isoechoic mass at the fourth layer of the gastric wall. Smears revealed cohesive clusters of small, uniform, round to polygonal cells with scant cytoplasm and round, hyperchromatic nuclei with homogeneous chromatin. Immunocytochemistry by liquid-based cytology was positive for smooth muscle actin. The cytologic diagnosis of a glomus tumor was confirmed by a specimen from the laparoscopic resection. Although the cytologic features of glomus tumors are quite distinctive, an immunocytochemical stain from a liquid-based cytology preparation can further help to ascertain the diagnosis.

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
The Hematopathology Study Group of the Korean Society of Pathologists conducted a nation-wide retrospective analysis of Korean pediatric lymphoma, to provide pathologic data on pediatric/adolescent lymphoma subtypes and features.
METHODS
All lymphoma cases of all age groups were collected during a recent 2 year-period (2005-2006) from 32 institutes in Korea. Among 3,686 lymphoma patients, 142 who were age 18 or less were classified according to the World Health Organization (WHO) classification.
RESULTS
Among 142 pediatric/adolescent lymphoma patients, Hodgkin lymphoma accounted for 21 (14.8%) and non-Hodgkin lymphoma (NHL) for 121 (85.2%). Hodgkin lymphoma appears to be more common in the pediatric/adolescent age group than in the all-ages group (14.8% vs 4.4%). T- and natural killer cell-NHL was more common in the pediatric/adolescent age group than in the all ages group (46.3% vs 22%). The majority of Korean pediatric/adolescent NHL cases was composed of Burkitt lymphoma, T- or B-lymphoblastic lymphoma, anaplastic large-cell lymphoma, and diffuse large B-cell lymphoma. For lymphoma patients under the age of 6 years, most had B-lymphoblastic or Burkitt lymphoma, which commonly presented at extranodal sites.
CONCLUSIONS
The distribution of lymphoma subtypes in the pediatric/adolescent age group is quite different from the distribution of adults, but it was quite similar to distribution in Western countries.

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.
