Abstract

Objective: The efficacy of preoperative 18F-fluoro-D-glucose (18F-FDG) positron emission tomography-computed tomography (PET-CT) in endometrium cancer is controversial. We examined the efficacy of PET-CT and the association between maximum standardized uptake value (SUVmax) and prognostic factors in endometrial cancer.Materials and Methods: Thirty patients with endometrial cancer underwent preoperative 18F-FDG/PET-CT. The patients were treated with abdominal hysterectomy with bilateral salpingo-oophorectomy, and bilateral systemic pelvic lymphadenectomy was planned for all patients; paraaortic lymphadenectomy was performed in patients with intermediate and high risk. Tumor histology, grade, depth of myometrial invasion, maximum tumor diameter, lymphovascular invasion, nodal status, and ovarian/adnexal metastases were recorded. Results: The mean primary tumor diameter was reported smaller in PET-CT and the effect size of PET-CT was -0.60. The kappa value was 0.06 for myometrial invasion. Pelvic lymph node metastasis was reported in 22.2% of patients in PET-CT. However, 3.7% of patients had pelvic lymph node metastasis. The kappa value for pelvic lymph node metastasis was 0.23, and sensitivity, specificity, and positive and negative predictive values were 100%, 80.7%, 16.6%, and 100%, respectively. Paraaortic lymph node metastasis in PET-CT was suspected in 10%. However, paraaortic lymph node metastasis was found in 6.7% in histopathologic analyses. The kappa value was 0.15. The sensitivity, specificity, and positive and negative predictive values of PET-CT for detecting paraaortic lymph node metastases were 100%, 93.7%, 66.6%, and 100%, respectively. Myometrial invasion and tumor diameter were the only important prognostic factors affecting SUVmax.Conclusion: According to our results, PET-CT has a limited role and diagnostic efficacy in endometrial cancer. The indications of FDG/PET-CT in endometrium cancer should be studied further and revised

Özet

Amaç: Endometriyal kanserde preoperatif 18F-floro-D-glukoz (18F-FDG) pozitron emisyon tomografi-bilgisayarlı tomografinin (PET-BT) etkinliği tartışmalıdır. Endometriyal kanserde PET-BT'nin etkinliğini ve maksimum standart uptake değeri (SUVmaks) ile prognostik faktörler arasındaki ilişkiyi inceledik.Gereç ve Yöntemler: Endometriyal kanserli otuz hastada preoperatif 18F-FDG/PET-BT vardı. Hastalar bilateral salpingo-oofrektomi ile abdominal histerektomi ile tedavi edildi ve her olguda bilateral sistemik pelvik lenfadenektomi planlandı, orta ve yüksek riskli hastalarda paraaortik lenfadenektomi yapıldı. Tümör histolojisi, grade, myometrial invazyon derinliği, maksimum tümör çapı, lenfovasküler invazyon, nodal durum, over/adneksiyel metastaz kaydedildi.Bulgular: Ortalama primer tümör çapının PET/BT'de daha küçük olduğu ve PET-BT'nin etki büyüklüğünün 0,60 olduğu rapor edildi. Myometrial invazyon için kappa değeri 0,06 idi. Pelvik lenf nodu metastazı PET-BT'de %22,2 olarak bulundu. Bununla birlikte, hastaların %3,7'sinde pelvik lenf nodu metastazı vardı. Pelvik lenf nodu metastazı için kappa değeri 0,23, duyarlılık, özgüllük, pozitif prediktif değeri ve negatif prediktif değeri sırasıyla %100, %80,7, %16,6 ve %100 idi. PET-BT'de, paraaortik lenf nodu metastazı açısından %10'unda şüphelenildi. Bununla birlikte, histopatolojik analizlerde paraaortik lenf nodu metastazı %6,7'sinde bulundu. Kappa değeri 0,15 idi. PET-BT'nin paraaortik lenf nodu metastazlarını saptamaya yönelik sensitivitesi, spesifitesi, pozitif prediktif değeri ve negatif prediktif değeri sırasıyla %100, %93,7, %66,6 ve %100 idi. SUVmaks'ı etkileyen tek önemli prognostik faktör, myometrial invazyon ve tümör çapı idi.Öz Sonuç: Sonuçlarımıza göre, PET-BT'nin endometriyum kanserinde sınırlı bir rolü ve tanısal etkinliği vardır. FDG/PET-BT'nin endometriyum kanseri endikasyonları daha fazla araştırılmalı ve gözden geçirilmelidir
