Objective: L1 cell adhesion molecule (L1CAM), as a member of the immunoglobulin superfamily, has recently been observed in a variety of human malignancies. However, no data of L1CAM are available for hepatocellular carcinoma (HCC). The aim of this study was to investigate the expression of L1CAM in HCC and determine its correlation with tumor progression and prognosis.Methods: One-hundred and thirty HCC patients who had undergone curative liver resection were selected and immunohistochemistry, Western blotting, and quantitative real time polymerase chain reaction (Q-PCR) were performed to analyze L1CAM expression in the respective tumors.Results: Immunohistochemistry, Western blotting, and Q-PCR consistently confirmed the overexpression of L1CAM in HCC tissues compared with their adjacent nonneoplastic tissues at both protein and gene level (both P <0.01). Additionally, the high expression of L1CAM was significantly associated with advanced tumor stage (P = 0.02) and advanced tumor grade (P = 0.03), respectively. Moreover, HCC patients with high L1CAM expression were significantly associated with lower 5-year overall survival (P <0.01) and lower 5-year disease-free survival (P <0.01), respectively. The Cox proportional hazards model further showed that L1CAM over-expression was an independent poor prognostic factor for both 5-year disease-free survival (P = 0.02) and 5-year overall survival (P = 0.008) in HCC.Conclusion: Our data suggest for the first time that L1CAM expression in HCC was significantly correlated with the advanced tumor progression and was an independent poor prognostic factor for both overall survival and disease-free survival in patients with HCC.Virtual slides: The virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1970024872761542. © 2012 Guo et al.; licensee BioMed Central Ltd.

To improve the diagnostic ability of leukoencephalopathy with cerebral calcifications and cysts (LCC), a rare central nervous system disease. The clinical manifestations, neuroimages and neuropathological features of a 19-year-old male patient were analyzed. A total of 20 cases from 14 literatures were reviewed. The patient was admitted with right limb weakness, cognitive decline, headache and blurred eyesight. Head CT scan showed multiple calcifications, cysts formation and leukoencephalopathy. Brain MRI showed several cysts in bilateral hemisphere, basal ganglia, thalamus and paraventricular areas. A mural nodule was noted inside one of the cyst, which was enhanced on the contrasted MRI. The wall of the cysts was partially enhanced, but not with the fluid inside the cysts. The corresponding CT calcifications foci showed on T1 and T2 with either both hyperintensity or both hypointensity, which was also partial enhanced. Extensive leukoencephalopathy was formed around the cysts and the ventricles. But neither Cho nor NAA changed a lot on MRS. Amplitude diagram of SWI series exhibited multiple round small dark signals all over the affected areas with mixed signals showed in the phase diagram, which indicated both calcifications and microbleeding at the lesions. Neuropathological examinations found no tumor cells in the operated cyst, and showed angiomatous small blood cells were dominant in the cyst wall. Hyaline degenerations, microcalcifications and hemosiderin deposition were observed. No obvious demyelination was discovered, while gliosis, numerous Rosenthal fibers and fibrinoid vascular necrosis were found around the lesions. The clinical, neuroimaging and pathological features of this patient were in accordance with the cases reported in the literatures. Neuroimaging is the most important method for the diagnosis of LCC. As small vessel lesions are probably closely related to the pathophysiology of LCC, SWI could be recommended to further reveal the etiology of LCC. Source

Background: SOX9 as a member of the SOX (SRY [sex determining region Y] box) gene superfamily has been previously demonstrated to be a proto-oncogene in a variety of malignancies. However, the clinical significance of SOX9 expression in hepatocellular carcinoma (HCC) remains unclear. The aim of this study was to investigate the expression of SOX9 in HCC and determine its correlation with tumor progression and prognosis.Methods: One-hundred and thirty HCC patients who had undergone curative liver resection were selected and immunohistochemistry, Western blotting, and quantitative real time polymerase chain reaction (Q-PCR) were performed to analyze SOX9 expression in the respective tumors.Results: Immunohistochemistry, Western blotting, and Q-PCR consistently confirmed SOX9 overexpression in HCC tissues compared with their adjacent nonneoplastic tissues (P ≪ 0.01). Additionally, immunostaining showed more SOX9 positive cells in the higher tumor stage (T3 ~ 4) and tumor grade (G3) than in the lower tumor stage (T1 ~ 2, P = 0.03) and tumor grade (G1 ~ 2, P = 0.01), respectively. Moreover, HCC patients with high SOX9 expression were significantly associated with lower 5-year overall survival (P ≪ 0.01) and lower 5-year disease-free survival (P ≪ 0.01), respectively. The Cox proportional hazards model further showed that SOX9 over-expression was an independent poor prognostic factor for both 5-year disease-free survival (hazards ratio [HR] = 2.621, 95% confidence interval[CI] = 1.548-5.829, P = 0.01) and 5-year overall survival (HR = 3.825, CI = 1.638-7.612, P = 0.003) in HCC.Conclusion: Our data suggest for the first time that the overexpression of SOX9 protein in HCC tissues is of predictive value on tumor progression and poor prognosis.Virtual slides: The virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/9029740396926377. © 2012 Guo et al; licensee BioMed Central Ltd.

Lung cancer is among the most prevalently occurring carcinomas worldwide, and reducing lung cancer mortality depends on early detection, diagnosis, and treatment. Given the rapid development of molecular biology and modern techniques for diagnosis and treatment, the study of serum tumor markers has gained extensive application in early diagnosis, treatment effect monitoring, and prognosis evaluation. Serum tumor markers possess the advantages of easy detection, noninvasive operation, and cost-effectiveness. This article reviews the progress in the study of serum tumor markers of lung cancer.

To improve the recolonization of long term interval between optic neuropathy and spinal cord injury of neuromyelitis optica. One 51-year old male patient with 37 years' interval between optic neuropathy and spinal cord injury of neuromyelitis optica underwent the examination of plasma and cerebrospinal fluid and head and spinal MRI examinations, who was also followed up. His clinical data were analyzed and related literature was reviewed. The myelin basic protein and IgG index in his cerebrospinal fluid was high, his oligoclonal band of cerebrospinal fluid was positive, and abnormal finding in visual evoked potential. Abnormal intramedullary long T(2) signals was showed in spinal cord MRI at T(1-7) segment. When diagnosed as neuromyelitis optica, the clinical symptom and signs was improved with corticosteroid and gamma globulin therapy. The patient was in stable condition at present. There could be a long term interval between optic neuritis and myelitis. One should pay attention to clinical features and imaging examination of subclinical lesion in spinal cord and brain and conoid the possibility of developing neuromyelitis optica or multiple sclerosis.
