Correlation between estrogen receptor status and clinicopathologic parameters in endometrial cancer: a comparative study by immunohistochemistry using different scoring systems / 中华病理学杂志

<p><b>OBJECTIVE</b>To compare the efficiency of three different estrogen receptor (ER) immunostaining scoring systems by analyzing the correlation between ER status and clinicopathologic features for prediction of prognosis of patients with endometrial carcinoma (EC).</p><p><b>METHODS</b>ER immunostaining (EnVision method) was performed in 160 type I EC and 39 type II EC paraffin samples and was scored by ASCO/CAP criterion, H-Score and Allred scoring system. Correlation between ER status and clinicopathologic features was statistically analyzed.</p><p><b>RESULTS</b>ASCO/CAP criterion, H-Score and Allred (cutoff point: 4-8) scoring system showed high concordance in the following aspects. In EC patients, ER status was significantly associated with presurgical CA125 levels (P = 0.015, P = 0.007, P = 0.023), histologic grades (all P < 0.01) and PR status (all P < 0.01). In type I EC cohort, ER status was significantly correlated with PR status (P = 0.008, P < 0.01, P < 0.01) and p53 status (P = 0.042, P = 0.001, P < 0.01). As of the predictive value of ER status for type I EC patient age, ASCO/CAP (P = 0.027) and H-Score criteria (P = 0.035) were both superior to Allred score system (P = 0.064). Among well-known predictive clinicopathologic parameters, including FIGO stage, lympho-vascular involvement, lymph node metastasis, depth of myometrial invasion and omental involvement, ASCO/CAP scoring offered a better correlation (P = 0.005, P = 0.002, P = 0.021, P = 0.067, and P = 0.067, respectively) than H-Score (P > 0.05) and Allred scoring system (P > 0.05).</p><p><b>CONCLUSIONS</b>Compared with H-Score and Allred scoring system, ASCO/CAP criterion is more closely correlated with predictive clinicopathologic parameters. Therefore it may be used as a simple, highly efficient prognostic indicator for EC patients in routine practice.</p>

Effect of high myopia on 24-hour intraocular pressure in patients with primary open-angle glaucoma / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>As intraocular pressure (IOP) and IOP fluctuation are known risk factors for glaucoma, it is important to understand the effects of high myopia on these ocular parameters. The aim of this study was to investigate if primary open-angle glaucoma (POAG) patients with high myopia exhibit higher IOP and greater IOP fluctuations at resting conditions over 24 hours.</p><p><b>METHODS</b>We designed a prospective control clinical study. Eighty-two eyes of 82 high-tension Chinese POAG patients only on prostaglandin analogue locally were divided into 3 groups according to various myopic grades (< -6.0 D, n = 27 and between -0.76 and -5.99 D, n = 33) or without myopia (-0.75 to 0.75 D, n = 22). Single time IOP at 10 am, mean corrected 24-hour IOP, mean corrected night IOP, 24-hour IOP fluctuation and IOPs of 10 am, 2 pm, 6 pm, 10 pm, 2 am, 6 am and 8 am were measured.</p><p><b>RESULTS</b>The IOP was higher in POAG patients with high myopia over those POAG alone in three ways: the elevated IOP value was 0.65 mmHg measured in single time IOP at 10 am, 0.84 mmHg in mean corrected 24-hour IOP, 0.97 mmHg in mean corrected night IOP. The 24-hour IOP fluctuation was lower in the two myopia groups than in non-myopia group. Further, using repeated measurement analysis of variance, there was no statistical significance among groups regarding the IOPs at the seven time points (P = 0.77) and there was no interaction between groups and time points (P = 0.71), but the difference of IOPs at the seven time points in same group was statistically significant (P = 0.01).</p><p><b>CONCLUSION</b>High-tension POAG patients with high myopia, even on pharmacological glaucoma therapy, still have higher IOP, but 24-hour IOP fluctuation at resting conditions was lower in these patients.</p>
