    Comparison of preoperative myometrial invasion on MRI with intraoperative frozen section in predicting adverse prognostic factors and survival in endometrioid endometrial cancer
    (2019) Akar, Serra; Guler, Abdul Hamid; Gul, Ayhan; Harmankaya, Ismail; Koplay, Mustafa; Tataroglu, Sumeyye Nur; Celik, Cetin
    Aim: There are no studies that have evaluated the accuracy of the finding of myometrial invasion in each modality in predicting adverse prognostic factors and survival. We compared the association of myometrial invasion on MRI and frozen section with presence of adverse prognostic factors and decreased disease-specific survival (DSS) in endometrioid endometrial cance. Material and Methods: A total of 149 patients diagnosed and treated surgically for endometrioid endometrial cancer at a single institution between 2010 and 2017 were included in the study. Accuracies of radiological myometrial invasion and frozen section myometrial invasion in predicting the histopathological myometrial invasion, other adverse prognostic factors and DSS were compared. Results: Frozen section had an accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 89.2%, 100.0%, 84.7%, 72.8% and 100.0%, respectively in diagnosing histopathological deep (≥50%) myometrial invasion with a kappa value of 0.876 (p<0.001). MRI had an accuracy, sensitivity, specificity, PPV and NPV of 71.3%, 55.8%, 80.6%, 63.2%, 75.3%, respectively with a kappa value of 0.392 (p<0.001) in predicting deep myometrial invasion. The accuracy of the finding of deep myometrial invasion on frozen section was higher than the finding of deep myometrial invasion on MRI in predicting the presence of adverse prognostic factors. However, the specificities and NPV’s were higher than their respective sensitivity and PPV values overall for both modalitiesd. Conclusion: Although MRI is frequently used in the preoperative evaluation of patients with endometrial cancer, the finding of deep myometrial invasion on MRI was not as accurate as that of frozen section in predicting the presence of adverse prognostic factors and poor survival. However, both test modalities demonstrated high specificity and NPV. As such both tests may provide higher efficacy in identifying patients without advanced disease who may not require complete lymph node dissection.

    Prognostic significance of tumor grade in early-stage endometrioid endometrial cancer
    (2019) Akar, Serra; Harmankaya, Ismail; Celik, Cetin
    Aim: Although tumor grade has no impact on endometrial cancer stage, it carries prognostic and therapeutic importance. Surgical management and adjuvant treatment following surgery in certain patients depends on a number of factors including tumor grade. Although grade 3 tumors are included in the high-intermediate risk group, there are data demonstrating that there is a slight difference in survival between patients with grade 1 and 2 tumors in early-stage disease. In this study, we aimed to investigate the association of grade with clinicopathological characteristics, recurrence-free and disease-specific survival in patients treated at our clinic and diagnosed with endometrioid endometrial cancer. Material and Methods: 279 patients with early FIGO Stage endometrioid endometrial cancer treated between 2009-2018 in a University hospital were included in the study. The associations between tumor grade with stage, lymphovascular space invasion (LVSI), myometrial invasion, tumor size, and survival were analyzed.Results: LVSI, ≥50% myometrial invasion, advanced stage and > 2 cm tumor size were significantly higher in grade 3 tumors compared to patients with grade 1 tumors. Recurrence-free and disease-specific survival were significantly lower in patients with grade 2 and 3 tumors compared to patients with grade 1 tumors. In multivariate analysis of RFS and DSS, tumor grade, LVSI and stage were independent prognostic factors.Conclusion: According to this study, grade 2 tumors may not differ significantly from grade 3 tumors in terms of survival. Therefore, due to the potential adverse prognosis associated with grade 2 and 3 tumors, vigilance for recurrence is warranted.

    Risk factors for pelvic and para-aortic lymph node metastasis in endometrial cancer: A retrospective analysis of 284 patients
    (2019) Celik, Cetin; Akar, Serra
    Aim: Hysterectomy is generally used to treat patients with endometrial cancer. Although lymphadenectomy can provide prognostic information, there are serious complications that can result from lymph node dissection. In order to avoid unnecessary surgical intervention, predictors related to both pelvic and para-aortic lymph node metastasis can be identified. In this study, we sought to define independent prognosticators for pelvic and para-aortic lymph node metastasis in women with endometrial cancer.Material and Methods: In total, 284 patients who were treated surgically between December 2009 and January 2019 were included in the study. The relationships between histopathological patient characteristics and definitive lymph node status were studied.Results: In multivariate analysis, lymphovascular space invasion (Adjusted Odds Ratio: 4.8, 95% Confidence Interval 2.4–17.5, p = 0.001) and deep myometrial invasion (Adjusted Odds Ratio 3.8, 95% Confidence Interval 1.1–14.3) were independent factors for pelvic lymph node metastasis. In multivariate analysis for para-aortic lymph node metastasis, lymphovascular space invasion (Adjusted Odds Ratio 5.9, 95% Confidence Interval 2.1–10.3) and pelvic lymph node metastasis (Adjusted Odds Ratio 20.8, 95% Confidence Interval 8.9–32.3) were independent prognostic factors significantly associated with the presence of para-aortic lymph node metastasis. Conclusion: The two independent histopathological factors identified for predicting the presence of pelvic lymph node metastasis were lymphovascular space invasion and outer half myometrial penetration of the tumor. Lymphovascular space invasion and pelvic lymph node metastasis were independently associated with the presence of para-aortic lymph node metastasis. Consideration of lymphadenectomy in patients who have evidence of outer half myometrial invasion or pelvic lymph node metastasis on preoperative imaging may be prudent. Lymphovascular space invasion and myometrial invasion findings on frozen section can be used before proceeding with lymphadenectomy in endometrial cancer.
