骨转移是许多恶性肿瘤常见的转移形式,骨转移的诊断对于恶性肿瘤的分期、治疗和预后判断有者极其重要的意义。目前骨转移主要诊断方法是注射鍀标记亚甲基二膦酸盐(^99 mTc-MDP)SPECT闪烁骨显像(bone imaging),骨显像是肺癌、乳腺癌和前列腺癌术前及复查的常规评价手段。^99 mTc-MDP骨显像是通过骨盐代谢活性的改变间接反应骨转移,由于骨显像灵敏度较高特异性相对较低的问题对于骨骼良性病变增加了假阳性的可能性;另外在核医学科^99MO-^99 mTc发生器的供应是获得^99 mTc-MDP的唯一途径,由于途径单一且受多种因素影响常出现断货现象,影响骨显像的正常进行。近年来探讨骨显像的多种检查手段(SPECT、^18F-NaF PETCT)运用成为关注点,经过对比研究探讨^18F-氟化钠PET-CT骨显像的应用作为解决上述问题措施的优势。  相似文献

目的 探讨血清前列腺特异性抗原(PSA)联合活体组织穿刺的Gleason评分对初诊前列腺癌患者转移风险的预测价值.方法 回顾性分析2019年1月至12月经前列腺活体组织穿刺病理学初次确诊、于海军军医大学(第二军医大学)长海医院行以68镓(68Ga)标记的靶向前列腺特异性膜抗原(PSMA)分子探针PSMA-11为示踪剂的PET-CT(68Ga-PSMA-11 PET-CT)检查的85例未经治疗的初诊前列腺癌患者的影像学及临床资料.85例患者中未发生肿瘤转移的有46例(无转移组)、发生肿瘤转移的有39例(转移组).以68Ga-PSMA-11 PET-CT是否发现转移病灶为二分类因变量,以PSAX(Gleason评分-5)为连续自变量,建立转移风险的logistic回归预测模型,并通过ROC曲线分析其诊断效能;用外部验证数据(n=20)对该模型进行检验,评估回归方程预测肿瘤转移的准确性.结果 转移组患者PSA水平、Gleason评分均高于无转移组[75.0(17.7~533.9)ng/mL vs 13.8(3.8~62.0)ng/mL,P<0.01;8(6~10)分vs 8(6~10)分,P=0.042].以PSAX(Gleason评分-5)作为连续自变量时,预测转移风险的 ROC AUC 为0.857(95%CI 0.772~0.942,P<0.01);PSA×(Gleason 评分-5)最佳界值为 130.62,对应的灵敏度为71.8%,特异度为95.7%,约登指数为0.675.回归方程logit(P)=0.019×PSA×(Gleason评分-5)-2.3对转移风险的预测准确度达81.2%(69/85).外部验证预测的PSA水平(Z=-1.616,P=0.106)和Gleason 评分(Z=-1.391,P=0.164)与构建模型数据相比差异无统计学意义,说明外部验证数据符合检验条件,其检验回归方程的准确度为85.0%(17/20).结论 PSA联合Gleason评分对初诊前列腺癌患者转移风险有较好的预测价值.  相似文献

BackgroundWe developed an artificial neural network (ANN) model to predict prostate cancer pathological staging in patients prior to when they received radical prostatectomy as this is more effective than logistic regression (LR), or combined use of age, prostate-specific antigen (PSA), body mass index (BMI), digital rectal examination (DRE), trans-rectal ultrasound (TRUS), biopsy Gleason sum, and primary biopsy Gleason grade.MethodsOur study evaluated 299 patients undergoing retro-pubic radical prostatectomy or robotic-assisted laparoscopic radical prostatectomy surgical procedures with pelvic lymph node dissection. The results were intended to predict the pathological stage of prostate cancer (T2 or T3) after radical surgery. The predictive ability of ANN was compared with LR and validation of the 2007 Partin Tables was estimated by the areas under the receiving operating characteristic curve (AUCs).ResultsOf the 299 patients we evaluated, 109 (36.45%) displayed prostate cancer with extra-capsular extension (ECE), and 190 (63.55%) displayed organ-confined disease (OCD). LR analysis showed that only PSA and BMI were statistically significant predictors of prostate cancer with capsule invasion. Overall, ANN outperformed LR significantly (0.795 ± 0.023 versus 0.746 ± 0.025, p = 0.016). Validation using the current Partin Tables for the participants of our study was assessed, and the predictive capacity of AUC for OCD was 0.695.ConclusionANN was superior to LR at predicting OCD in prostate cancer. Compared with the validation of current Partin Tables for the Taiwanese population, the ANN model resulted in larger AUCs and more accurate prediction of the pathologic stage of prostate cancer.  相似文献

Objective To test the clinical value of using Tc-99m MIBI scintimammography (Tc-99m MIBI SMM) to differentiate nodular lesions in breasts and detect axillary lymph node metastases of breast cancer. Methods The subjects consisted of sixty female patients exhibiting unilateral palpable breast mass. The early and delay static acquisitions were undertaken in all subjects at 10 and 90 min after injection with Tc-99m MIBI. The acquisition included three positions: anterior supine, left lateral prone and right lateral prone. A special device for SMM which was developed by our laboratory was used. The ratio of [(T-B)/(NT-B)] was calculated as radioactivity of mass to that of opposite corresponding tissue, and [(T-B)/(NT-B)]≥1.21 was used as the cut-off for semi-quantitative discrimination of malignancy from benignity in semi-quantitative analysis. The final diagnosis was obtained from histology examination in all subjects. Results Using Tc-99m MIBI SMM to differentiate between nodular lesions in breasts, the diagnostic sensitivity and specificity were 92.9% and 90.6% respectively, the positive predictive value 89.7%, the negative predictive value 93.5%, and the accuracy 91.7%. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy obtained with Tc-99m MIBI SMM for detecting axillary lymph node metastases were 83.3%, 86.1%, 80%, 88.6% and 85% respectively. Conclusions It is suggested that Tc-99m MIBI SMM may be not only valuable in differentiating malignant lesions from benign nodular masses of breast, but also helpful in detecting axillary lymph node metastases of breast cancer.  相似文献
