BACKGROUND Platelets have been reported to act as transporters of tumor-originated vascular endothelial growth factor (VEGF), contributing to tumor angiogenesis and progression. Serum VEGF per platelet count, as an indirect theoretical estimate of VEGF in platelets, may predict the malignant potential of tumors. However, its prognostic significance is still(More)
The tumor suppressor gene, TP53, is located on chromosome 17p13.1 and is critical for DNA repair, cell-cycle control, and apoptosis. TP53 also plays a crucial function in the tumorigenesis of lung cancer. Inactivation of TP53 via genetic alterations such as missense mutations is often associated with lung cancer. In this study, potential association of TP53(More)
BACKGROUND The balance in the immune system between immune surveillance against non-self-antigens and tolerance of self-antigens is known to be associated with the prognosis of breast cancer patients. However, immunologic signals in tumor microenvironment according to biological characteristics of cancer cells have not been clearly elucidated. CD4(+) T(More)
As software becomes more complicated and larger, software engineer’s requirements analysis become important and uneasy activity. This paper proposes a requirements analysis supporting system that supports informal requirements analysis. The proposed system measures the similarity between requirement sentences to identify possible redundancies and(More)
In order to evaluate the role of BRCA1 and BRCA2 germline mutations in Korean patients with sporadic breast cancer, 97 patients with sporadic breast cancer were analyzed for mutations in the BRCA1 and BRCA2 coding regions, by using a combination of fluorescent-conformation sensitive gel electrophoresis (F-CSGE) and direct sequencing. Fifty-five distinct(More)
Urokinase plasminogen activator receptor (uPAR) plays a major role in cancer invasion and metastasis and uPAR expression is correlated with a poor prognosis in various cancer types. Moreover, the expression of uPAR is increased under hypoxic conditions. Nitric oxide (NO) and its metabolites produced by inducible nitric oxide synthase (iNOS) are important(More)
Tissue microenvironment is an important determinant of carcinogenesis. We demonstrate that ionizing radiation, a known carcinogen, affects cancer frequency and characteristics by acting on the microenvironment. Using a mammary chimera model in which an irradiated host is transplanted with oncogenic Trp53 null epithelium, we show accelerated development of(More)
Although cisplatin-based chemotherapy is the standard of care for advanced transitional cell carcinoma, tolerability is a challenging issue in unfit patients. This study was conducted to evaluate the efficacy, toxicity, and tolerability of the combination of gemcitabine and carboplatin in unfit patients with advanced transitional cell carcinoma. Thirty-one(More)
Published studies on the association between the vascular endothelial growth factor (VEGF) gene 936 C/T polymorphism and breast cancer risk are inconclusive, and a meta-analysis is required to verify the association. Nine studies, including a total of 4,973 cases and 5,035 controls, were subjected to meta-analysis. When all eligible subjects were pooled for(More)
OBJECTIVE The purpose of this study was to determine the incidence and risk factors of infections associated with implantable venous access ports (IVAPs). MATERIALS AND METHODS From August 2003 through November 2011, 1747 IVAPs were placed in our interventional radiology suite. One hundred forty four IVAPs were inserted in patients with hematologic(More)
