Abstract
PDF - Background
CDKN2A is a tumor suppressor gene that encodes the cell cycle inhibitor protein p16. Homozygous deletion of the CDKN2A gene has been associated with shortened survival in isocitrate dehydrogenase (IDH)–mutant gliomas. This study aimed to analyze the prognostic value of p16 and to evaluate whether p16 immunohistochemical staining could be used as a prognostic marker to replace CDKN2A genotyping in diffuse gliomas.
Methods
p16 immunohistochemistry was performed on tissue microarrays of 326 diffuse gliomas with diagnoses that reflected IDH-mutations and 1p/19q codeletion status. The results were divided into three groups (negative, focal expression, overexpression) according to the presence and degree of p16 expression. Survival analysis was performed to assess the prognostic value of p16 expression.
Results
A loss of p16 expression predicted a significantly worse outcome in all glioma patients (n=326, p<.001), in the IDH-mutant glioma patients (n=103, p=.010), and in the IDH-mutant astrocytoma patients (n=73, p=.032). However, loss of p16 expression did not predict the outcome in the IDH-wildtype glioma patients (n=223, p=.121) or in the oligodendroglial tumor patients with the IDH-mutation and 1p/19q codeletion (n=30, p=.457). Multivariate analysis showed the association was still significant in the IDH-mutant glioma patients (p=.008; hazard ratio [HR], 2.637; 95% confidence interval [CI], 1.295 to 5.372) and in the IDH-mutant astrocytoma patients (p=.001; HR, 3.586; 95% CI, 1.649 to 7.801). Interestingly, patients who presented with tumors with p16 overexpression also had shorter survival times than did patients with tumors with p16 focal expression in the whole glioma (p< .001) and in IDH-mutant glioma groups. (p=.046).
Conclusions
This study suggests that detection of p16 expression by immunohistochemistry can be used as a useful surrogate test to predict prognosis, especially in IDH-mutant astrocytoma patients. -

Abstract
PDF
- BACKGROUND
Fine needle aspiration (FNA) of the thyroid is a useful tool for the evaluation of benign or malignant thyroid nodules. The improvements in the quality of cytological preparations using the liquid-based cytology (LBC) method have been well-documented. The principal objective of this study was designed to evaluate the diagnostic adequacy, sensitivity, and specificity of the thyroid FNA comparing a conventional smear with the LBC adapted with the filtration method described herein.
METHODS
One hundred ninety eight cases of FNA samples obtained from May 2009 to September 2009 were included in this study. All patients were subjected to ultrasound-guided aspiration twice at a target lesion by a radiologist and two types of slides were prepared using conventional smear and LBC.
RESULTS
When compared with conventional method, the cellularity was reduced in LBC. However, the malignant tumor cells evidenced the larger and more vesicular nuclei, prominent nucleoli, and distinct nuclear membranes in LBC. Thirty two cases (16.16%) of conventional smear were inadequate, but 96 cases (48.49%) of LBC were inadequate.
CONCLUSIONS
Most of the slides using CellprepPlus(R) LBC evidenced lower cellularity and clearer background. However, the conventional smears were found to generate much more applicable samples than CellprepPlus(R) LBC. -
