AIM:To evaluate the predictive value of superficial retinal capillary plexus(SRCP)and radial peripapillary capillary(RPC)for visual field recovery after optic cross decompression and compare them with peripapillary nerve fiber layer(pRNFL)and ganglion cell complex(GCC).METHODS:This prospective longitudinal observational study included patients with chiasmal compression due to sellar region mass scheduled for decompressive *** estimating equations were used to compare retinal vessel density and retinal layer thickness preand post-operatively and with healthy *** regression models were used to assess the relationship between preoperative GCC,pRNFL,SRCP,and RPC parameters and visual field recovery after ***:The study included 43 eyes of 24 patients and 48 eyes of 24 healthy *** RPC and SRCP vessel density and pRNFL and GCC thickness were lower than healthy controls and higher than postoperative *** best predictive GCC and pRNFL models were based on the superior GCC[area under the curve(AUC)=0.866]and the tempo-inferior pRNFL(AUC=0.824),and the best predictive SRCP and RPC models were based on the nasal SRCP(AUC=0.718)and tempo-inferior RPC(AUC=0.825).There was no statistical difference in the predictive value of the superior GCC,tempo-inferior pRNFL,and tempo-inferior RPC(all P>0.05).CONCLUSION:Compression of the optic chiasm by tumors in the saddle area can reduce retinal thickness and blood *** reduction persists despite the recovery of the visual field after decompression ***,pRNFL,and RPC can be used as sensitive predictors of visual field recovery after decompression surgery.

Background Biomarkers in breast neoplasms provide invaluable information regarding prognosis and help determining the optimal treatment. We have examined the possible correlation between cancer stem cell （CSC）-like markers （CD133, paired box gene 2 protein （PAX2）, epithelial specific antigen （ESA））, and a new membrane estrogen receptor （G-protein coupled receptor 30 （GPR30）） in invasive ductal breast carcinomas with known clinicopathological parameters, tumor recurrence, and expression of some known biomarkers. Methods In 74 invasive ductal breast carcinomas, we investigated the protein expression of these molecular markers by immunohistochemistry, and their associations with known clinicopathological parameters, tumor recurrence, and expression of some known biomarkers. We studied the interrelationship between the expressions of these proteins. Results CD133, a putative CSC marker, was positively related to tumor size, tumor stage, and lymph node metastasis. PAX2 was negatively correlated with tumor recurrence. ESA, one of the breast CSC markers, was an indicator of tumor recurrence. GPR30 was associated with hormone receptors. Despite the correlation between GPR30 and the nuclear estrogen receptor, the expression was dependent. Positive staining of GPR30 in tumors displayed a significant association with high C-erbB2 expression and a tendency for tumor recurrence. A positive relationship between GPR30 and CD133 existed. Conclusion Detecting the expression of CD133, PAX2, ESA, and GPR30 in invasive ductal breast carcinomas may be of help in more accurately predicting the aggressive properties of breast cancer and determining the optimal treatment.
