Abstract PDF

Background

Simian virus 40 (SV40), a polyomavirus, was discovered as a contaminant of a human polio vaccine in the 1960s. It is known that malignant mesothelioma (MM) is associated with SV40, and that the virus works as a cofactor to the carcinogenetic effects of asbestos. However, the reports about the correlation between SV40 and MM have not been consistent. The purpose of this study is to identify SV40 in MM tissue in Korea through detection of SV40 protein and DNA.

Methods

We analyzed 62 cases of available paraffin-blocks enrolled through the Korean Malignant Mesothelioma Surveillance System and performed immunohistochemistry for SV40 protein and real-time polymerase chain reaction (PCR) for SV40 DNA.

Results

Of 62 total cases, 40 had disease involving the pleura (64.5%), and 29 (46.8%) were found to be of the epithelioid subtype. Immunostaining demonstrated that all examined tissues were negative for SV40 protein. Sufficient DNA was extracted for real-time PCR analysis from 36 cases. Quantitative PCR of these samples showed no increase in SV40 transcript compared to the negative controls.

Conclusions

SV40 is not associated with the development of MM in Korea.

Abstract PDF

Background

Fibroadenoma (FA) and phyllodes tumor (PT) are stromal tumors of breast and are histologically similar. There are no established differences in tumorigenesis and oncogene expression among them. Ras homolog enriched in brain (RHEB) plays an important role in cell growth and cell-cycle control, histone deacetylase 1 (HDAC1) is an important factor in breast tumor progression and prognosis, and WEE1 homolog (WEE1) functions as a tumor suppressor. No studies on the expressional differences of these proteins in FA and PT have been reported to date.

Methods

The expression of these proteins in FA, PT, and normal breast was compared. We used 102 cases of FA and 25 cases of benign PT.

Results

In epithelial cells, the expression of RHEB, HDAC1, and WEE1 was lowest in PT, higher in FA, and most enhanced in normal breast. In addition, the expression of RHEB and HDAC1 was higher in the stromal cells of PT than in FA and normal breast.

Conclusions

Both epithelial and stromal cells of FA and PT express these proteins, which indicates that epithelial cells play an important role in the development of stromal tumors. In addition, the expressional differences of these proteins may be associated with the tumorigenesis of breast stromal tumors.

Abstract PDF

Background

Histone deacetylase 1 (HDAC1) is associated with the expression and function of estrogen receptors and the proliferation of tumor cells, and has been considered a very important factor in breast tumor progression and prognosis. Several studies have reported an association between HDAC1 expression and poorer prognosis in cancers including breast cancer, with a few exceptions. However, because of the dearth of studies on HDAC1 expression in breast cancer, its significance for breast cancer prognosis has not been well defined. Therefore, we examined HDAC1 expression in invasive ductal carcinoma (IDC), the most common breast cancer, and investigated its potential prognostic significance.

Methods

We used 203 IDC tissue samples. Immunohistochemical stains for HDAC1 and real-time polymerase chain reaction for HDAC1 mRNA were performed and the results were compared to generally well-established prognostic factors in breast cancer and patient survival rates.

Results

HDAC1 expression was significantly reduced in proportion to higher histologic grade, higher nuclear pleomorphism score, and higher mitotic counts, and with lower estrogen receptor expression. Furthermore, it was significantly associated with the survival rate.

Conclusions

HDAC1 expression is a good prognostic indicator in IDC.

Abstract PDF: BACKGROUND
:Although clinicopathologic differences have been described between Epstein-Barr virus (EBV)-positive and negative gastric adenocarcinomas, the pathogenetic basis for these differences remains unclear. In this study, efforts were made to confirm that expression of EBV-latent membrane protein (LMP1) and immunohistochemical characteristics of EBVpositive gastric adenocarcinomas.
METHODS
We investigated genomic deletion, and RNA & protein expression of the EBV-LMP1, as well as immunohistochemical protein expression of transforming growth factor (TGF)-beta1, TGF-bata RII, p21, p16, E2F1, thymidylate synthase, and NF-kappaB in relation to EBV positive gastric adenocarcinoma.
RESULTS
A total of 38 Epstein-Barr Virus Encoded RNA-positive and 80 negative gastric carcinomas were examined. A 30 bp DNA deletion in the EBV-LMP1 gene, initiating at codon 342, was detected in 94.4% of EBVpositive cases. By RT-PCR and western blotting, EBV-LMP1 mRNA and protein expressions were absent in all cases, re-gardless of DNA deletion. No significant differences in TGF-bata1, TGF-betaRII, p21, NF-kappaB, E2F1, or thymidylate synthase expression were identified. However, the decreased expression of p16 was found in 84.2% of EBV-positive carcinomas, relative to only 57.5% of EBV-negative tumors (p=0.024).
CONCLUSION
EBV-LMP1 DNA deletion, mRNA and protein losses are highly prevalent in EBV-positive gastric adenocarcinoma among Korean patients, along with decreased p16 expression.

Abstract PDF: BACKGROUND
The role of the anaphase-promoting complex (APC) is to promote the degradation of mitotic cyclins and other substrates involved in sister chromatid adhesions. The APC appears to be responsible for the degradation of cyclin B and may have a potential role in the loss of control concerning cell proliferation in mammalian cells. However, a direct link between the defects in the APC components and oncogenesis has not been estabilished. This study investigates the relationship between APC expression and variable prognostic factors in invasive ductal carcinoma of the breast.
METHODS
We evaluated 108 cases of invasive ductal carcinoma surgically resected from January, 1996 to May, 2000 at Wonju Christian Hospital, Wonju College of Medicine, Yonsei University. Immunohistochemical stains for APC, estrogen receptor, and Ki-67 were done in paraffin sections using the avidin-biotin complex method. The results were compared with clinical and pathologic parameters and flow cytometric DNA analysis factors.
RESULTS
Forty cases (37.0%) showed immunopositive reactions for APC. The APC positivity in histologic grades 1, 2, and 3 were 28 cases (84.4%), 33 cases (60.0%), and 7 cases (35.0%), respectively (p=0.0011). The APC expressions in cases with the number of mitosis of less than 10, 10-19, and more than 20 per 10 high power fields, were noted in 37 cases (75.5%), 26 cases (63.4%), and 5 cases (27.8%), respectively (p=0.0016). The mean value of the Ki-67 labeling index was 221.7 in the APC-positive group and 317.9 in the APC-negative group (p= 0.0091). DNA flow cytometric analysis revealed higher APC expressions in cases with diploid patterns (p=0.0095). The APC expression rate increased significantly with decreasing histologic grade, with decreasing mitotic activity, in cases with a low Ki-67 labeling index, and those in the diploid group (p<0.05). The APC expression was not statistically correlated with clinical stage, tumor size, and estrogen receptor status.
CONCLUSIONS
These findings suggest that positive APC expression may be considered as a good prognostic factor of invasive ductal carcinoma, and loss of APC expression may be related with the progression of breast cancer.

Abstract PDF: Apocrine carcinoma of the breast is a very rare subtype. Although it has no clinical differences from usual ductal carcinoma of the breast, it should be categorized as a subtype of breast carcinoma because the cells of apocrine carcinoma reveal characteristic abundant eosinophillic cytoplasms with intraductal apical snouting as well as round or oval nuclei and central macronucleoli. On fine needle aspiration cytology, the cells of apocrine carcinoma have a lot of similarity to benign or reactive apocrine cells of the breast. Therefore, it is difficult to make a differential diagnosis of apocrine carcinoma from mammary neoplasms with similar cytologic findings unless the subtle cytologic differences are recognized. We report the cytologic and histologic findings of a case of apocrine carcinoma in the breast of a 40-year-old female patient. After the fine needle aspiration cytology, she received the lumpectomy and lymph node dissection. The cellularity was moderate to high. The cytoplasmic borders of tumor cells of three-dimensional clusters were relatively distinctive, and the cytoplasm was abundant, eosinophilic, and granular. Although the nuclear/cytoplasmic ratio was low, the nuclei of the cells were variable in size and shape with prominent macronucleoli. Histologically, it was a typical invasive apocrine carcinoma, showing numerous cytoplasmic lysosomes and mitochondriae on electron microscopy.

Abstract PDF: BACKGROUND
The anaphase promoting complex (APC) promotes the degradation of mitotic cyclins as well as other substrates involved in sister chromatid adhesion. This study was carried out to examine the relationship between the APC expression and the clinicopathological variables, in an attempt to determine the role of the APC in the proliferation of lung cancer and to evaluate the possibility of an aberrant APC function in surgically resected squamous cell carcinomas and adenocarcinomas of the lung.
METHODS
Immunohistochemical staining was performed for APC, Ki-67, cyclin B1, Cdc2, MMP-2 and VEGF in 55 cases of squamous cell carcinoma and 34 cases of adenocarcinoma of the lung, using the avidin-biotin-peroxidase method.
RESULTS
The immunohistochemical stains for APC revealed a positive reaction in 49 cases (55.1%). The APC expression level was higher in the cyclin B1-positive group (p= 0.01), the Cdc2-positive group (p=0.001), the MMP-2-positive group (p=0.03), the group with lymph node metastasis (61.4% vs 48.9%), and the group with stage II/III cancer (60.7%) compared with those with stage I (42.9%).
CONCLUSIONS
The APC may have an aberrant function, such as a change in its role in controlling the cell cycle, and might be associated with the invasiveness and proliferation of tumor cells.

Abstract PDF: Inflammatory myofibroblastic tumor, also known as inflammatory fibrosarcoma, has been frequently diagnosed as inflammatory pseudotumor. Although there are six cases reported as inflammatory pseudotumors or inflammatory myofibroblastic tumors in the lung, no cases of pulmonary inflammatory myofibroblastic tumor with features of inflammatory fibrosarcoma have been reported in Korea. We experienced a case of inflammatory myofibroblastic tumor (inflammatory fibrosarcoma)characterized by high cellularity, severe nuclear pleomorphism, necrosis, or increased mitoticcounts. A 31-year-old male patient with a solitary pulmonary nodule on the routine chest x-rayreceived a right lower lobectomy. The tumor was an ovoid solid mass with multifocal necrosis, showing diffuse irregular proliferation of spindle cells with high cellularity and focal nuclear pleomorphism, admixed with dense lymphoplasmacytic cells. Although spindle cells are focally immunoreactivefor smooth muscle actin, the ultrastructural examination failed to demonstrate smooth muscledifferentiation. In cases of inflammatory myofibroblastic tumor (inflammatory fibrosarcoma), a completeexcision and close follow-up without radical surgery, radiation, or chemotherapy are needed.
