Deregulation of G1 cyclins has been reported in several human and rodent tumors including colon cancer. To investigate the expression pattern of G1 cyclins in 1,2- dimethyl-hydrazine dihydrochloride (DMH)-induced rat colon carcinogenesis, we studied the expression of cyclin D1 and cyclin E by quantitative reverse transcription-polymerase chain reaction (RT-PCR) analysis and immunohistochemistry (IHC). The mRNA level of cyclin D1 was increased 1.2-fold in adenocarcinomas but not significantly in adenomas, when compared with normal rat colonic mucosa (p<0.05). The cyclin E mRNA level was increased 2.7-fold in adenomas and 3.3-fold in adenocarcinomas (p<0.05). The PCNA mRNA level was also increased 1.9-fold in adenomas and 1.8-fold in adenocarcinomas (p<0.05). Immunohistochemical staining revealed exclusive nuclear staining of the neoplastic cells for cyclin D1, cyclin E and PCNA. Cyclin D1 expression was detected in 56.3% of the adenomas and in 61.5% of the adenocarcinomas examined, whereas cyclin E expression was detected in 87.5% of the adenomas and in 92.3% of the adenocarcinomas. Overall, cyclin D1, cyclin E and PCNA expression was significantly increased at both the mRNA and protein levels in normal colonic mucosa, adenomas and adenocarcinomas, but there was no significant difference in the degree of expression of these genes in adenomas and adenocarcinomas. Our results indicate that the overexpression of cyclin D1 and cyclin E may play an important role during the multistage process of rat colon carcinogenesis, at a relatively early stage, and may disturb cell-cycle control in benign adenomas, and thereafter, participate in tumor progression.

Glassy cell carcinoma is a histologic subtype of cervical cancer with distinct pathologic features and it has an aggressive biologic course. It was first described by Glucksmann and Cherry in 1956 as a poorly differentiated adenoquamous carcinoma and commented on its poor prognosis, unresponsiveness to traditional modes of therapy, and often associated with pregnancy. The characteristic histologic features are defined as follows: 1) cells with a moderate amount of cytoplasm resembling ground glass, 2) a fairly distinct cell membrane that stains with eosin or PAS, 3) large nuclei with prominent nucleoli. We present two cases of glassy cell carcinoma of the cervix successfullyl treated by neoadjuvant chemotherapy and radical hyterectorny, with a brief review of literatures.

BACKGROUND/AIMS: Periostin is an extracellular matrix protein and is known to be related to the metastatic potential and prognosis of cancer. However, few studies have investigated the expression level of periostin and its association with prognoses in hepatocellular carcinoma. Therefore, we analyzed periostin overexpression in hepatocellular carcinoma and its implication for prognoses. METHODS: We evaluated 149 patients who underwent surgical resection between 2006 and 2010. Tissue microarrays were constructed from hepatocellular carcinoma tissue and adjacent nontumor tissue, and immunohistochemistry was performed. RESULTS: A high periostin level was observed more frequently in cases of multiple tumors (odds ratio [OR], 2.826; 95% confidence interval [CI], 1.224 to 6.527; p=0.013), positive microvascular invasion (OR, 2.974; 95% CI, 1.431 to 6.181; p=0.003), and advanced stage disease (OR, 3.032; 95% CI, 1.424 to 6.452; p=0.003). Patients with high periostin expression had significantly (p=0.002) lower overall survival rates than those with low periostin expression (90.3%, 66.1%, and 56.2% vs 97.7%, 85.1%, and 77.5% at 1, 3, and 5 years). CONCLUSIONS: We found that a combination of periostin overexpression and microvascular invasion in hepatocellular carcinoma was correlated with a poor prognosis and can be a good prognostic marker for hepatocellular carcinoma.

BACKGROUND: Chemerin is a novel adipokine that is associated with inflammation and adipogenesis. However, it remains unclear whether chemerin is involved in patients with cardiovascular disease. We investigated whether the serum chemerin levels of Korean patients with coronary artery disease correlated with specific cardiometabolic parameters. METHODS: In total, 131 patients, all of whom had coronary artery stenosis exceeding 50%, participated in this study. Their serum chemerin levels and cardiometabolic parameters were measured. The serum chemerin levels of two groups of patients were compared; those with one stenotic vessel (n=68) and those with multiple stenotic vessels, including left main coronary artery disease (n=63). RESULTS: Serum chemerin levels correlated positively with the degree of coronary artery stenosis and fasting glucose, triglyceride, total cholesterol, low density lipoprotein cholesterol, and high sensitive C-reactive protein levels. The group with multiple stenotic vessels, including left main disease, had higher chemerin levels than the group with one stenotic vessel (t=-2.129, P=0.035). Multiple binary logistic regression showed chemerin was not an independent risk factor of multiple vessel disease (odds ratio, 1.018; confidence interval, 0.997 to 1.040; P=0.091). CONCLUSION: Serum chemerin levels have a significant correlation with several cardiometabolic risk factors and the degree of coronary artery stenosis in Korean patients with coronary artery disease. However, multiple binary logistic regression showed chemerin was not an independent risk factor of multiple vessel disease. Additional investigations are necessary to fully elucidate the role of chemerin in cardiovascular disease.

Neointimal hyperplasia mainly develops within several months of coronary stent deployment, after which it stabilizes. Although it was widely accepted, particularly during the bare-metal stent (BMS) era, that in-stent restenosis (ISR) generally does not present as an acute coronary syndrome (ACS), but rather as a gradual recurrence of angina symptoms, recent data have shown that a substantial number of patients with ISR present as ACS. There has also been consistent postmortem evidence of plaque rupture secondary to atherosclerotic change within the neointima of a BMS. We report here a case of ACS in which intravascular ultrasound and optical coherent tomographic assessments revealed neointimal atherosclerotic change and ruptured plaque 10 years after BMS deployment.

PURPOSE: Although the resectability of hepatocellular carcinoma has increased due to recent advances in diagnostic methods and surgical techniques, the long-term results are unsatisfactory due to their invasiveness and frequent association with cirrhosis. This study was designed to identify the prognostic factors affecting the long term survival and recurrence of tumors in patients having undergone a hepatic resection for a hepatocellular carcinoma. METHODS: Between June 1996 and March 2002, 51 consecutive patients underwent a hepatic resection for a hepatocelluar carcinoma at the Inha University Hospital. The overall cumulative and disease free survival rates for these patients were analysed. Twenty-five clinicopathological factors were evaluated by univariate and multivariate analyse to determine any significant prognostic factors. RESULTS: The cumulative 1, 3 and 5-year survival rates were 84, 70 and 58%, respectively. There were 26 recurrences, and the 1, 3 and 5-year disease free cumulative survival rates were 60, 53 and 31%, respectively. From the univariate analysis, all the factors associated with ascites (P=0.0000), total bilirubin (P=0.0015), albumin (P=0.0271), prothrombin time (P=0.0392), HBe antigen (P=0.0283), Child classification (P=0.0000), celluar differentiation (P=0.0043) were found to correlate with the overall survival. From a Cox regression analysis, the HBe antigen (P=0.019), ascites (P=0.028) were found to be independent prognostic factors of the overall survival. The only factor with an independent effect on disease free survival was the HBe antigen (P=0.037). CONCLUSION: Because prognosis of HBe antigen-positive patients with ascites is poor, frequent postoperative follow up surveys in these patients are needed.

Adrenocortical carcinoma is a rare malignant endocrine tumor which accounts for about 0.05% to 0.2% of all carcinomas. Three clinical patterns can be encountered. In 30% of the cases, a mass syndrome without any clinical evidence of hypersecretion is presented as abdominal pain, a palpable abdominal mass, abdominal distension, and weight loss. In 60% of the cases, an overt clinical syndrome of hypersecretion is of almost purely hypercortisolism in 30% of such cases, vilirization in 22%, feminization in 10%, hyperaldosteronism in 2.5%, and a mixed secretion in 35%. In the remaining 10% of the cases, an adrenal `incidentaloma' is found incidentally during evaluation of the other disease. About 70% to 80% of patients are diagnosed with an advanced stage (III or IV) and metastasis has occured in 20% to 40% of the patients at the time of presentation. Early surgery an with adrenalectomy is the only means of cure. The prognosis is poor with a 5-years survival rate of 16% to 34% due to initial diagnosis at an advanced stage. Recently, we experienced two cases of adrenocortical carcinomas. In case I, a 62-year-old female patient presented with a clinical syndrome of hypercortisolism and had an extensive local invasion of stage IV; in case II, a 49-year-old male patient complained of abdominal pain and distension without any clinical syndrome of hypersecretion and had stage IV liver metastasis.
