Endometrial and Ovarian Cancer with MR Imaging Importance of Serum HE4 and CA 125 Levels in the Extent of Disease at Evaluation

Abstract

Objective: Currently, no clinically useful tumor marker is available for primary diagnosis in endometrial cancer. Human epididymis protein-4 (HE-4) has high sensitivity and specificity as a tumor marker. Further, HE-4 has been shown to be elevated in early stage endometrial cancer and is more sensitive than CA 125. In our study, CA 125 and HE-4 reputation as a tumor marker for diagnosis of ovarian and endometrial cancer with the use of both the availability and affect the way we investigated the rate of diagnosis. Materials and Methods:Here 20 patients with ovarian cancer, 26 patients with endometrial cancer, which had been histologically diagnosed, and 40 healthy volunteers were included. Peripheral blood samples were taken and serum CA 125 and HE-4 were tested.Results: Serum CA 125 and HE-4 levels in patients with ovarian cancer were found to be significantly higher than those in healthy volunteers (p<0.05). Receiver-operating characteristic (ROC) analysis was performed. For patients with ovarian cancer and healthy controls, the CA 125 (0.83) and HE-4 (0.84) levels showed increased sensitivity (95%). There was no significant difference in the CA 125 levels in patients with endometrial cancer and healthy controls (p>0.05), whereas HE-4 levels were found to be higher in patients with endometrial cancer than in healthy controls (p<0.05). ROC analysis was performed. For endometrial cancer patients and healthy controls, the CA 125 (0.59) and HE-4 (0.63) levels showed increased sensitivity (88.5%). Conclusion:In ovarian and endometrial cancer, wherein early diagnosis is the most important factor for prognosis and survival, HE-4 is a new serum tumor marker that can be used with the aim of noninvasive diagnoses. For early diagnosis, the concomitant use of CA 125 and HE-4 is more effective and reliable than using either of them alone.Keywords: Ovary, endometrium, cancer, diagnosis, tumor marker ÖZ Amaç: CA 125 erken evre over kanserlerinin sadece %50'sinde yükselir. Endometrium kanserinde klinik pratikte rutin olarak kullanılan tümör marker yoktur. Human epididimis protein-4 (HE-4) over kanserlerinde yüksek sensitivite ve spesifiteye sahiptir. Endometrial kanserde CA 125 den daha sensitif olduğu ve erken evrede yükseldiği gösterilmiştir. Çalışmamızda CA 125 ve HE-4'ün over ve endometrium kanserinde tümör markerı olarak kullanılabilirliğini ve ikisinin birlikte kullanımın teşhis oranını ne şekilde etkileyeceğini araştırdık.Gereç ve Yöntem: Çalışmamıza histopatolojik olarak tanısı konulan 20 over kanseri, 26 endometrium kanseri hasta ile jinekolojik problemi olmayan 40 sağlıklı gönüllü dahil edilmiştir. MR görüntülemesiyle FIGO sistemine göre evreleri belirlendi. Hastalardan preoperatif olarak ve sağlıklı gönüllülerden periferik kan alınarak serum CA 125 ve HE-4 düzeyleri çalışıldı.Bulgular: Over kanseri hastalarının serum CA 125 ve HE-4 düzeyleri sağlıklı kontrollerinkinden anlamlı yüksek bulundu (p<0,05). ROC (Receiver Operatör Characteristic) analizi uygulandığında over kanseri hastalarında CA 125 (0,83) ve HE...

HE4 as a Biomarker for Endometrial Cancer

“…The literature regarding the benefit of combining HE4 and CA125 for detection of EC is mixed. Several studies have shown a nonsignificant increase in sensitivity of the combination of serum HE4+CA125 for detection of EC compared to using HE4 alone [26,29,115], but this comes at a cost to specificity [38,48]. In contrast, other studies have shown no significant difference combining serum HE4 and CA125 compared to HE4 alone for EC detection [27,35].…”
