Adenocarcinoma of the endometrium (also known as endometrial cancer, or more broadly as uterine cancer or carcinoma of the uterine corpus) is the most common malignancy of the female genital tract in the United States. It is estimated that 65,950 new uterine cancer cases will have occurred in 2022, with 12,550 deaths resulting from the disease. Endometrial carcinoma includes pure endometrioid cancer and carcinomas with high-risk endometrial histology (including uterine serous carcinoma, clear cell carcinoma, carcinosarcoma [also known as malignant mixed Müllerian tumor], and undifferentiated/dedifferentiated carcinoma). Stromal or mesenchymal sarcomas are uncommon subtypes accounting for approximately 3% of all uterine cancers. This selection from the NCCN Guidelines for Uterine Neoplasms focuses on the diagnosis, staging, and management of pure endometrioid carcinoma. The complete version of the NCCN Guidelines for Uterine Neoplasms is available online at NCCN.org.

Uterine leiomyosarcoma (ULMS) is an aggressive malignancy for which hysterectomy is often the primary treatment approach. Due to the rarity of these tumors, the role of oophorectomy in the management of ULMS is not clearly established. This study aimed to describe the impact of oophorectomy and estrogen/progesterone (ER/PR) receptor status on clinical outcomes and survival.Women with ULMS treated between 1/2013 and 1/2018 were retrospectively identified. Clinical data was collected; descriptive statistics were performed and predictors of overall survival (OS) and event free survival (EFS) were analyzed using Cox regression and Kaplan-Meier methodology.189 patients were included. Median age was 53 years (20-84 years). The majority of patients had stage IB (58%) and grade 3 (94%) tumors. On pathologic analysis, ER/PR expression was positive in 41% and 33%, respectively. The majority of patients (179, 94.7%) underwent surgery as their primary treatment approach, of which 51 (28.5%) had ovarian conservation. 59.0% were treated with chemotherapy, while 9.9% received radiation therapy. 84.6% of patients experienced a recurrence, but there was no difference in EFS or OS by oophorectomy status, including among those with uterine confined disease. Additionally, ER/PR status was not independently associated with EFS/OS (p = 0.14, p = 0.07) nor did it impact survival among those with ovaries left in situ.Oophorectomy did not influence OS, even though many tumors were hormone receptor positive. ER/PR status was not independently associated with survival, including in the subset of women with uterine confined disease and those who had undergone oophorectomy.

ObjectivePelvic floor dysfunction is a common adverse effect of uterine cancer treatment. In this study we compared patient-reported outcomes regarding pelvic floor dysfunction among uterine cancer survivors after hysterectomy and bilateral salpingo-oophorectomy, surgery and brachytherapy, or surgery and external beam radiotherapy with or without brachytherapy versus women who had a hysterectomy for benign indications.MethodsWe used the validated 20-item Pelvic Floor Distress Inventory to assess lower urinary distress, colorectal distress, and pelvic organ prolapse dysfunction in each treatment group. Pelvic floor dysfunction-related quality of life in these domains was compared across treatment modalities using the Pelvic Floor Impact Questionnaire-7. Treatment type, body mass index, comorbidities, and number of vaginal births were obtained from medical records. A zero-inflated negative binomial regression model was used to assess the association of treatment regimens and covariates relative to the non-cancer cohort.ResultsA total of 309 surveys were analyzed. The median age of the patients at surgery was 58 years (range 20–87) and the median age at survey completion was 66 years (range 34–92). Most participants reported experiencing at least one symptom of pelvic floor dysfunction (76% by Pelvic Floor Distress Inventory-2). The type of treatment had no effect on overall pelvic floor dysfunction on multivariate analysis (all p>0.05). Worse urinary-related symptoms were associated with higher body mass index at surgery (OR 1.41), higher age at time of survey (OR 1.07), and higher numbers of vaginal births (OR 1.43) (all pConclusionsOverall, pelvic floor dysfunction did not significantly vary by treatment modality. Our findings suggest complex interactions among age, body mass index, and parity as to how uterine cancer treatment affects pelvic floor quality of life, which should be considered in the choice of treatment strategy and patient counseling.

BackgroundEstablishing care preferences and selecting a prepared medical decision-maker (MDM) are basic components of advance care planning (ACP) and integral to treatment planning. Systematic ACP in the cancer setting is uncommon. We evaluated a systematic social work (SW)-driven process for patient selection of a prepared MDM.MethodsWe used a pre/post design, centered on SW counseling incorporated into standard-of-care practice. New patients with gynecologic malignancies were eligible if they had an available family caregiver or an established Medical Power of Attorney (MPOA). Questionnaires were completed at baseline and 3 months to ascertain MPOA document (MPOAD) completion status (primary objective) and evaluate factors associated with MPOAD completion (secondary objectives).ResultsThree hundred and sixty patient/caregiver dyads consented to participate. One hundred and sixteen (32%) had MPOADs at baseline. Twenty (8%) of the remaining 244 dyads completed MPOADs by 3 months. Two hundred and thirty-six patients completed the values and goals survey at both baseline and follow-up: at follow-up, care preferences were stable in 127 patients (54%), changed toward more aggressive care in 60 (25%), and toward the focus on the quality of life in 49 (21%). Correlation between the patient’s values and goals and their caregiver’s/MPOA’s perception was very weak at baseline, improving to moderate at follow-up. Patients with MPOADs by study completion had statistically significant higher ACP Engagement scores than those without.ConclusionA systematic SW-driven intervention did not engage new patients with gynecologic cancers to select and prepare MDMs. Change in care preferences was common, with caregivers’ knowledge of patients’ treatment preferences moderate at best.

The NCCN Guidelines for Uterine Neoplasms provide recommendations for diagnostic workup, clinical staging, and treatment options for patients with endometrial cancer or uterine sarcoma. These NCCN Guidelines Insights focus on the recent addition of molecular profiling information to aid in accurate diagnosis, classification, and treatment of uterine sarcomas.

To determine if a reduced-field-of-view (rFOV) diffusion intravoxel incoherent motion (IVIM) sequence can differentiate the imaging characteristics of tumors with microsatellite instability (MSI) from those that are microsatellite stable (MSS) in patients with clinical FIGO stage IA endometrial cancer and if MRI can be used to determine MSI status.Sagittal rFOV diffusion-weighted images were obtained in 12 patients on a 3T scanner using six b-values (0, 50, 100, 150, 200, and 600). These images were used to derive apparent diffusion coefficient (ADC), true diffusion coefficient (DSix patients had MSS tumors and six had MSI tumors. MSS tumors had a significantly higher ADC value (P = 0.03) and DIVIM, ADC and D1 J. Magn. Reson. Imaging 2017;45:1216-1224.

To compare the clinical usefulness of reduced field-of-view diffusion-weighted imaging (rFOV) with other imaging techniques in determining the depth of myometrial invasion (DMI) in endometrial cancer.In this prospective study we reviewed 3T magnetic resonance images of 51 patients with clinical Stage I endometrial cancer who underwent total abdominal hysterectomy with bilateral salphingoopherectomy within 3 days after imaging. rFOV with apparent diffusion coefficient reconstruction was obtained in three standard planes followed by sagittal T2 -weighted (T2 WI) images and 3D dynamic T1 -weighted and contrast-enhanced imaging (DCE MRI). Two radiologists with expertise in imaging gynecologic cancers evaluated images independently. The DMI was recorded on imaging and correlated with surgical pathology results. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for DMI were calculated (50% vs.50%).Compared with sagittal T2 WI + DCE MRI, rFOV imaging yielded greater specificity (82.2% vs. 90.0%, positive predictive value (42.8% vs. 60.0%), and accuracy (84.0% vs. 92%) for DMI determined by reader 1 and greater the sensitivity (83.3% vs. 100%) for DMI determined by reader 2. The error of measurement of DMI as a continuous variable in millimeters did not differ significantly between the rFOV and pathology results (P0.21). However, there was a statistically significant difference for the DMI measured on the dynamic sequence. The DMI on DCE was greater than that seen on pathology at P = 0.02.rFOV can be used to assess DMI in clinical Stage I endometrial cancer.
