ABSTRACT
Objective To analyze the risk factors and characteristics of bone metastases in patients with prostate cancer. Methods Patients who were diagnosed as prostate cancer by biopsy and histopathologic analysis between June 2006 and June 2016 were included in this study. The clinical data of the patients were reviewed, and the demographic data, laboratory examination results and Gleason score were recorded. The correlations between clinical factors and bone metastasis were analyzed, and the risk factors of bone metastasis were identified. Results A total of 585 patients were recruited in this study, including 228 with bone metastasis and 357 without bone metastasis. Of the patients with bone metastasis, the incidence of pelvic metastasis was the highest, accounting for 81.58%, followed by spin (63.16%) and rib (58.33%), and the incidence of clavicle metastasis was the lowest (14.47%). Logistic regression analysis showed that age 85.5U/L, prostate-specific antigen >79.88μg/L and Gleason score >7.5 were the risk factors of bone metastasis in prostate cancer. ROC curve analysis showed that the sensitivity of diagnosing bone metastasis was 56.1%, 66.7%, 68.4% and 56.1%, and the specificity was 56.6%, 81.8%, 70.0% and 65.3%, respectively for above 4 factors. Conclusions The most common site of bone metastasis in patients with prostate cancer is pelvis. Patients' age, concentrations of plasma ALP and PSA, and Gleason score are the risk factors for bone metastasis in patients with prostate cancer.
ABSTRACT
Objective To investigate the safety and feasibility of fast track surgery (FTS)in patients with vaginal hysterectomy for non -prolapsed uterus.Methods 1 1 0 cases of vaginal hysterectomy for non -prolapsed ute-rus with benign uterine disease were randomly divided into two groups:fast track group (n =55)and conventional group (n =55).The operative time,intraoperative blood loss,postoperative nausea and vomiting,anal exhaust time, postoperative hospital stay,medical cost and perioperative complications were compared between the two groups. Results In FTS group,the incidence rate of postoperative nausea and vomiting,the postoperative anal exhaust time, hospital stay,cost of hospitalization were 1 6.4%,(1 3.73 ±2.41 )h and (4.38 ±1 .08 )d,(7 541 .00 ± 253.1 7)yuan,respectively,which in the control group were 36.4%,(1 8.56 ±1 .54 )h,(4.89 ±1 .26 )d, (8 1 55.1 5 ±495.89)yuan,the differences were statistically significant between the two groups (χ2 =5.67,t =-1 2.53,-2.28,-8.1 7,all P 0.05).Conclusion FTS has good security.It can short the hospitalization time,reduce medical costs and improve the quality of life in patients who underwent vaginal hysterectomy for non -prolapsed uterus with benign uterine disease.
ABSTRACT
Objective To evaluate the diagnostic value of dual-source CT angiography (DSCTA) for intracranial aneurysms.Methods The data of DSCTA and digital subtraction angiography (DSA) were collected from 95 patients with subarachnoid hemorrhage (SAH).The efficacies of detection and description of morphologic features of intracranial aneurysms were analyzed retrospectively.Results A total of 117 aneurysms in 88 patients were detected with DSCTA.Two patients were suspected of having aneurysms,and no aneurysrms were detected in 5 patients.These patients were reexamined with DSA,4 were diagnosed as having aneurysm,and the aneurysms were not detected in 3 patients.DSA results were considered as gold standard,the specificity,sensitivity and accuracy of DSCTA for the detection of intracranial aneurysms were 100％,96.7％and 96.8％,respectively.The larger volume of intracranial aneurysm was,the higher the sensitivity of DSCTA diagnosis would be.Even for small aneurysms,the sensitivity of DSCTA diagnose was more than 90％.In addition,tmeasurement results of the maximum diameter and neck width of aneurysms measured by DSCTA were almost consistent with DSA.Condclusions SCTA is a non-invasive,quick,reliable,and effective method,and can provide accurate imaging information for surgery.The specificity and sensitivity of the diagnosis of aneurysms with DSCTA are almost the same with DSA.It has more advantages than DSA in the emergency operation of intracranial aneurysms.
