Endometrial cancer is the eighth most common cancer worldwide, and its prognosis depends on various factors, with myometrial invasion having a major impact on prognosis. Optimizing MRI protocols is essential, and it would be useful to improve the diagnostic accuracy without the need for other sequences. We conducted a retrospective, single-center study, which included a total of 87 patients with surgically confirmed primary endometrial cancer, and who had undergone a pre-operative pelvic MRI. All exams were read by an experienced radiologist dedicated to urogenital radiology, and the depth of myometrial invasion was evaluated using T2-Weighted Images (T2WI) and fused T2WI with Diffusion-Weighted Images (DWI). Both results were compared to histopathological evaluations. When comparing both sets of imaging (T2WI and fused T2WI-DWI images) in diagnosing myometrial invasion, the fused images had better accuracy, and this difference was statistically significant (p < 0.001). T2WI analysis correctly diagnosed 82.1% (70.6–88.7) of cases, compared to 92.1% correctly diagnosed cases with fused images (79.5–97.2). The addition of fused images to a standard MRI protocol improves the diagnostic accuracy of myometrial invasion depth, encouraging its use, since it does not require more acquisition time.

Abstract Objective: To evaluate the added value of diffusion-weighted imaging (DWI) in the preoperative assessment of myometrial invasion in endometrial cancer, in comparison with T2-weighted imaging (T2WI) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Materials and Methods: This was a retrospective study involving 44 women with endometrial cancer who underwent preoperative 1.5 T MRI. Two radiologists, both of whom were blinded to the histopathology reports, performed a consensus interpretation of the depth of myometrial invasion and of the stage of the cancer, considering three sets of sequences: T2WI, DCE-MRI+T2WI, and DWI+T2WI. Accuracy, sensitivity, specificity, positive predictive value, and negative predictive value were calculated for each set. The accuracy was compared with p-value adjustment by the Benjamini-Hochberg procedure. Results: Among the 44 patients evaluated, DWI+T2WI demonstrated better diagnostic performance in assessing deep myometrial invasion and correctly staged more patients (n = 41) than did DCE-MRI+T2WI (n = 34) and T2WI (n = 22). The superior diagnostic accuracy of DWI+T2WI was statistically significant in comparison with T2WI (p < 0.05) but not in comparison with DCE-MRI+T2WI (p > 0.05). Conclusion: The addition of DWI apparently improves the diagnostic accuracy of MRI in the preoperative assessment of the depth of myometrial invasion in endometrial cancer, which may be particularly helpful in patients for whom contrast agents are contraindicated.

Objectives: The objectives of this study is to investigate the correlation of magnetic resonance imaging (MRI) in predicting the depth of myometrial invasion, cervical involvement and lymph node involvement and actual histopathological findings in the women with endometrial cancer. Methods: This is a reterospective study of the patients of endometrial cancer from Nov 2011 to Jan 2016 who underwent Surgery (Total abdominal Hystrectomy with B/l salpingoophorectomy with peritoneal washings with b/l pelvic lymphadenectomy with or without para aortic lymphadenectomy) at our centre Max Superspeciality Hospital. CE MRI Pelvis has been done pre operatively in every patient. After the surgery Histopathological reports of the specimen checked and compared with MRI findings of that case. The purpose of the study is to evaluate the validity of MRI findings of endometrial cancer in comparison to final histopathological findings. Results: For the detection of myometrial invasion, overall sensitivity of MRI is 93.9%, specificity is 66.6%, for cervical involvement Senstivity is 60% and specificity 1s 93.75% and for detection of lymph node involvement sensitivity is 66.6% and specificity is 93.5%. Most common Finding on MRI is thickened endometrium with disruption of Junction jone. Conclusions: Preoperative pelvic MRI is a sensitive method of identifying invasion to the myometrium in endometrial cancer. MRI Is a sensitive noninvasive modality in predicting locoregional spread in ca endometrium. Senstivity in detecting Myometrial invasion is high but sensitivity is less in detecting cervical involvement and lymph node involvement is less.

Abstract Introduction The sentinel lymph node (SLN) concept represents advancement in the management of the endometrial cancer (EC). We aim to assess the performance of the SLN procedure; its positive predictive value (PPV) and negative predictive value (NPV); in stage I of EC (FIGO2009). Method A prospective study is conducted in our institution. We perform a double detection of the SLN (radiolabel Tc 99 microsulfur colloid and a color method using patent blue) followed by pelvic lymphadenectomy with or without paraaortic lymphadenectomy. A pelvic MRI is performed to determine myometrial invasion and nodal status. The injection of Tc 99m colloid occurs the day prior to surgery. The injection into the stroma of the cervix at the 3 and 9 o'clock positions was performed by an oncologist surgeon with the assistance of a nuclear medicine physician. Preoperative lymphoscintigraphy was obtained after 90-120 minutes. We inject into the cervical stroma 2cc of patent blue similar to the Tc99 injection. A gamma detecting probe is used to locate radioactive lymph nodes. The SLNs identified then are labelled as radioactive and/or blue. No frozen-section analysis was performed. Results For the pathological analysis of the SLN, Haematoxylin Eosin is used. If there is no metastasis detected, an ultra staging protocol using different anti-cytokeratines is conducted. Studies have shown that this approach is possible having satisfactory results when conducted by dedicated surgical, radiology and pathology team. We look forward to our outcomes to illustrate those results. Take-home message Sentinel lymph node is a good alternative for gynecological cancer

Objective: Surgical procedure and adjuvant treatment of type I endometrial cancer were affected by some variables assessed preoperatively. Diffusion-weighted magnetic resonance imaging (DWI) is a promising modality in evaluating myometrial invasion and cervical involvement, investigating the diagnostic values of DWI in assessing myometrial invasion and cervical involvement. Methods: A cross-sectional study was conducted. This study involved all type I endometrial cancer patients in Dr. Cipto Mangunkusumo Hospital from April 2016 until April 2019. The depth of myometrial invasion and cervical involvement was examined using 1.5-T MR unit. The result was compared to the surgical pathologic findings as the reference standard. Results: 34 types I endometrial cancer patients were enrolled in this study. The sensitivity of DWI in evaluating myometrial invasion and cervical involvement in type I endometrial cancer was 94.12% and 57.14%, while the specificity was 64.71% and 92.59%, respectively. Conclusion: DWI can provide reliable prognostic variable information about the myometrial invasion and cervical involvement in the preoperative preparation of endometrial cancer patients.

The aim of this study was to assess the diagnostic accuracy of subjective ultrasound evaluation of myometrial invasion of endometrial cancer and to compare its accuracy to objective methods. All consecutive patients with histologically proven endometrial cancer, who underwent ultrasound evaluation followed by surgical staging between January 2009 and December 2011, were prospectively enrolled. Myometrial invasion was evaluated by subjective assessment using ultrasound (<50% or ≥50%) and calculated as deepest invasion/normal myometrium ratio (Gordon’s ratio) and as tumor/uterine anteroposterior diameter ratio (Karlsson’s ratio). Histological assessment from hysterectomy was considered the gold standard. Altogether 210 patients were prospectively included. Subjective assessment and two objective ratios were found to be statistically significant predictors of the myometrial invasion (AUC = 0.65, p value < 0.001). Subjective assessment was confirmed as the most reliable method to assess myometrial invasion (79.3% sensitivity, 73.2% specificity, and 75.7% overall accuracy). Deepest invasion/normal myometrium (Gordon’s) ratio (cut-off 0.5) reached 69.6% sensitivity, 65.9% specificity, and 67.3% overall accuracy. Tumor/uterine anteroposterior diameter (Karlsson’s) ratio with the same cut-off reached 56.3% sensitivity, 76.4% specificity, and 68.1% overall accuracy. The subjective ultrasound evaluation of myometrial invasion performed better than objective methods in nearly all measures but showed statistically significantly better outcomes only in case of sensitivity.
