Pancreatic cancer, primarily pancreatic ductal adenocarcinoma (PDAC), accounts for 2.4% of cancer diagnoses and 5.8% of cancer death annually. Early diagnoses can improve 5-year survival in PDAC. The aim of this systematic review was to determine the sensitivity, specificity and diagnostic accuracy values for MRI, CT, PET&PET/CT, EUS and transabdominal ultrasound (TAUS) in the diagnosis of PDAC.
A systematic review was undertaken to identify studies reporting sensitivity, specificity and/or diagnostic accuracy for the diagnosis of PDAC with MRI, CT, PET, EUS or TAUS. Proportional meta-analysis was performed for each modality.
A total of 5399 patients, 3567 with PDAC, from 52 studies were included. The sensitivity, specificity and diagnostic accuracy were 93% (95% CI=88-96), 89% (95% CI=82-94) and 90% (95% CI=86-94) for MRI; 90% (95% CI=87-93), 87% (95% CI=79-93) and 89% (95% CI=85-93) for CT; 89% (95% CI=85-93), 70% (95% CI=54-84) and 84% (95% CI=79-89) for PET; 91% (95% CI=87-94), 86% (95% CI=81-91) and 89% (95% CI=87-92) for EUS; and 88% (95% CI=86-90), 94% (95% CI=87-98) and 91% (95% C=87-93) for TAUS.
This review concludes all modalities, except for PET, are equivalent within 95% confidence intervals for the diagnosis of PDAC.
胰腺癌，主要是胰腺导管腺癌（PDAC），每年占癌症诊断病例的2.4%，癌症死亡病例的5.8%。早期诊断可提高PDAC患者的5年生存率。本系统评价的目的是确定MRI、CT、PET&PET/CT、EUS和经腹超声（TAUS）在诊断PDAC时的灵敏度、特异度和诊断准确性值。
进行一项系统评价，以识别报告MRI、CT、PET、EUS或TAUS诊断PDAC的灵敏度、特异度和/或诊断准确性的研究。对每种检查方法进行了成比例Meta分析。
共纳入来自52项研究的5399例患者，其中3567例为PDAC患者。MRI的灵敏度、特异度和诊断准确性分别为93%（95%CI=88-96）、89%（95%CI=82-94）和90%（95%CI=86-94）；CT分别为90%（95%CI=87-93）、87%（95%CI=79-93）和89%（95%CI=85-93）；PET分别为89%（95%CI=85-93）、70%（95%CI=54-84）和84%（95%CI=79-89）；EUS分别为91%（95%CI=87-94）、86%（95%CI=81-91）和89%（95%CI=87-92）；TAUS分别为88%（95%CI=86-90）、94%（95%CI=87-98）和91%（95%CI=87-93）。
本评价得出结论，除PET外，所有检查方法在诊断PDAC时在95%置信区间内等效。
