A third possibility is delayed fixation and false negative results for the primary tumor, which could explain some of the gain of ER in recurrence.
第三个可能的原因是原发肿瘤延迟固定和假阴性结果，这个能解释复发病灶的ER阳性表达。
Timing is important because inflammation, which is present in the early weeks following treatment of the tumor, can cause false positive PET scans.
时间非常重要，因为在肿瘤治疗后早期炎症能使PET扫面出现假阳性。
Conclusion Joint detection of different tumor markers will increase the specificity of the immunoassay and lower its rate of false positivity.
结论多项肿瘤标志物联合检测可提高特异性，降低假阳性率。
