RESUMO
The use of glucagon-like peptide-1 receptor agonists (GLP-1RA) has experienced rapid growth amidst the obesity epidemic in the United States. While originally developed for glucose control in Type 2 Diabetes Mellitus, the scope of these agents now extends to encompass weight loss and cardiovascular risk reduction. GLP-1RAs have the potential to induce significant weight loss, in combination with lifestyle modifications, among adults who are overweight or obese. Furthermore, these agents demonstrate efficacy in ameliorating hyperglycemia, enhancing insulin sensitivity, regulating blood pressure, improving cardiometabolic parameters, mitigating kidney dysfunction, and potentially reducing the risk of several obesity-related cancers. Drug-related toxicity is primarily gastrointestinal and active management can prevent drug discontinuation. Obesity is associated both with an increased incidence of malignancy but also with decreased survival. More research is needed to evaluate the potential use of GLP-1RA to modify the endocrine function of adipocytes, regulate the chronic inflammatory state associated with obesity, and prospective applications in oncology. These agents can impact patients with gynecologic malignancies both through their direct mechanism of action as well as potential drug toxicity.
RESUMO
Invasive lobular breast cancer (ILC) is characterized by a relatively high risk for late recurrence and a unique metastatic pattern with an increased risk for metastasis to gynecologic organs and peritoneum. We present a unique case of recurrent ILC with metastasis to the abdominal peritoneum as well as the uterine myometrium and cervix. Treatment was complicated by the discovery of concomitant uterine carcinosarcoma. This patient was effectively treated with a combination of hormonal therapy for her metastatic ILC and a combination of chemotherapy and immunotherapy for uterine carcinosarcoma. Molecular evaluation revealed a characteristic CDH1 mutation within the ILC and a PI3KCA mutation within the uterine carcinosarcoma, both of which have been linked to epithelial-to-mesenchymal transitions. Examination of the tumor immune microenvironment revealed proportionally more cytotoxic NK cells. This robust immune infiltration may be an indicator of the response to immunotherapy observed in this tumor or a result of the metastatic breast cancer within the uterus. This report provides a characterization of the molecular and immunologic landscape in this case with metastatic ILC and uterine carcinosarcoma.

RESUMO
BACKGROUND: Mismatch-repair (MMR)/microsatellite instability (MSI) status has therapeutic implications in endometrial cancer (EC). The authors evaluated the concordance of testing and factors contributing to MMR expression heterogeneity. METHODS: Six hundred sixty-six ECs were characterized using immunohistochemistry (IHC), MSI testing, and mut-L homolog 1 (MLH1) methylation. Select samples underwent whole-transcriptome analysis and next-generation sequencing. MMR expression of metastatic/recurrent sites was evaluated. RESULTS: MSI testing identified 27.3% of cases as MSI-high (n = 182), MMR IHC identified 25.1% cases as MMR-deficient (n = 167), and 3.8% of cases (n = 25) demonstrated discordant results. A review of IHC staining explained discordant results in 18 cases, revealing subclonal loss of MLH1/Pms 1 homolog 2 (PMS2) (n = 10) and heterogeneous MMR IHC (mut-S homolog 6 [MSH6], n = 7; MLH1/PMS2, n = 1). MSH6-associated Lynch syndrome was diagnosed in three of six cases with heterogeneous expression. Subclonal or heterogeneous cases had a 38.9% recurrence rate (compared with 16.7% in complete MMR-deficient cases and 9% in MMR-proficient cases) and had abnormal MMR IHC results in all metastatic recurrent sites (n = 7). Tumors with subclonal MLH1/PMS2 demonstrated 74 differentially expressed genes (determined using digital spatial transcriptomics) when stratified by MLH1 expression, including many associated with epithelial-mesenchymal transition. CONCLUSIONS: Subclonal/heterogeneous MMR IHC cases showed epigenetic loss in 66.7%, germline mutations in 16.7%, and somatic mutations in 16.7%. MMR IHC reported as intact/deficient missed 21% of cases of Lynch syndrome. EC with subclonal/heterogeneous MMR expression demonstrated a high recurrence rate, and metastatic/recurrent sites were MMR-deficient. Transcriptional analysis indicated an increased risk for migration/metastasis, suggesting that clonal MMR deficiency may be a driver for tumor aggressiveness. Reporting MMR IHC only as intact/deficient, without reporting subclonal and heterogeneous staining, misses opportunities for biomarker-directed therapy. PLAIN LANGUAGE SUMMARY: Endometrial cancer is the most common gynecologic cancer, and 20%-40% of tumors have a defect in DNA proofreading known as mismatch-repair (MMR) deficiency. These results can be used to guide therapy. Tests for this defect can yield differing results, revealing heterogeneous (mixed) proofreading capabilities. Tumors with discordant testing results and mixed MMR findings can have germline or somatic defects in MMR genes. Cells with deficient DNA proofreading in tumors with mixed MMR findings have DNA expression profiles linked to more aggressive characteristics and cancer spread. These MMR-deficient cells may drive tumor behavior and the risk of spreading cancer.

OBJECTIVE: We sought to assess the impact of antibiotic (ABX) and proton-pump inhibitor (PPI) use on progression-free (PFS) and overall survival (OS) in patients treated with adjuvant platinum-based chemotherapy (PC) for endometrial cancer (EC). METHODS: A retrospective, single-institution cohort study of EC patients treated with ≥four cycles of adjuvant PC following surgical staging from 2014 to 2020. Demographics and clinicopathologic features, including ABX and PPI use, were compared using χ2 and Fisher's exact tests. Univariate and multivariable analyses were performed, and survival outcomes were compared using the log-rank test. RESULTS: Of 325 patients, 95 (29%) received ABX, and 80 (24.6%) received PPI. ABX were associated with decreased 3-year PFS (49.9% vs. 66%; p = 0.0237) but not 3-year OS (68.9% vs. 79.9%; p = 0.0649). ABX targeting gram-positive bacteria were associated with decreased 3-year PFS (21.2% vs. 66.0% vs. 55.4%; p = 0.0038) and 3-year OS (36.5% vs. 79.9% vs. 75.6%; p = 0.0014) compared to no ABX and other ABX, respectively. PPI use was associated with decreased 3-year PFS (46.9% vs. 66.0%; p = 0.0001) and 3-year OS (60.7% vs. 81.9%; p = 0.0041) compared to no PPI. On multivariable regression analysis controlling for confounders including stage, histology, grade, radiation, and co-morbidities, PPI use was independently associated with worse PFS (HR 1.96, 95% CI 1.25-3.08; p = 0.0041) and OS (HR 2.06, 95% CI 1.01-4.18, p = 0.04). CONCLUSION: In this retrospective cohort study, we demonstrate that PPI use is independently associated with worse PFS and OS in patients with EC treated with PC. ABX use was associated with worse PFS on univariate analysis only. There is an unmet need to understand how PPI, ABX, and, potentially, the microbiome impact the effectiveness of chemotherapy in EC patients.

OBJECTIVE: We sought to provide a contemporary report on stage IVB endometrial carcinoma (2009 FIGO criteria) and applied the 2023 FIGO staging criteria to this population. METHODS: Retrospective review of patients who underwent cytoreduction for stage IVB endometrial carcinoma (2009 FIGO criteria) from 2014 to 2020 was performed. Demographics, clinicopathologic factors, and outcomes were recorded. Disease burden and distribution were determined by imaging, operative notes, and pathology reports. Patients were re-staged according to 2023 FIGO staging criteria. Categorical variables were compared using χ2 or Fisher's exact test, and Kaplan-Meier curves compared survival outcomes using the log-rank test. RESULTS: Eighty-eight cases were included. Most patients (63.6%) were not suspected to have stage IVB (2009 FIGO criteria) disease prior to surgery. Seventy-two percent of patients underwent primary cytoreduction, and 12 (19%) were suboptimal. Median progression-free survival (PFS) was 12 months (95% CI 10-16 months), and median overall survival (OS) was 38 months (95% CI 19-61 months). Degree of cytoreduction (p = 0.0101) and pelvic-confined metastatic disease (p = 0.0149) were significant prognostic factors, while distant metastases were not associated with worse outcomes. For those patients who underwent primary cytoreduction, number (p = 0.0453) and diameter (p = 0.0192) of tumor deposits were associated with PFS. When 2023 FIGO staging criteria were applied, 58% of patients underwent change in stage, and 8% did not meet criteria for complete staging. PFS was significantly different based on 2023 FIGO staging (p = 0.0307); a trend in OS was also noted (p = 0.0550). CONCLUSION: Stage IVB endometrial carcinoma (2009 FIGO criteria) encompasses a diverse cohort of patients, where certain clinicopathologic features, tumor burden, and degree of cytoreduction are associated with outcomes. The 2023 FIGO staging criteria significantly improves our ability to risk-stratify patients.

Purpose: We sought to evaluate the contribution of mismatch repair (MMR) status to traditional risk stratification algorithms used to predict nodal involvement and recurrence in a large single-institution cohort. Methods: Endometrioid endometrial cancer (EC) cases from 2014-2020 were evaluated. MMR immunohistochemistry (IHC) was performed universally. Uterine factors assessed in the Mayo criteria were used to retrospectively classify patients as low or high risk for lymphatic spread. Patients were classified according to risk for recurrence using GOG 99 and PORTEC criteria. Associations were evaluated using chi-square and t-tests and contributing factors assessed using logistic regression models. Results: 1,514 endometrioid EC were evaluated; 392 (25.9%) were MMR (MMR) deficient of which 80.4% of MMR defects were associated with epigenetic silencing of MLH1. Epigenetic MMR defects were significantly more likely to be high risk for lymph node (LN) metastasis based on Mayo criteria (74.9% vs 60.6%, p=<0.001) and with the presence of LN metastasis (20.3 vs 10.5%, p=0.003) compared to MMR proficient tumors. Tumors with epigenetic MMR defects were significantly more likely to be classified as high or high intermediate risk using GOG99 and PORTEC criteria. Furthermore, cases with epigenetic MMR defects classified as low or low intermediate risk were significantly more likely to recur (GOG99 p=0.013; PORTEC p=0.008) and independently associated with worse disease-free survival (DFS). MMR status was found to be independently associated with worse DFS (HR 1.90; 95% CI 1.34-2.70; p=0.003) but not overall survival. Conclusion: While MMR deficient EC has been associated with poor prognostic features in prior reports; we demonstrate that only epigenetic MMR defects have poorer outcomes. Epigenetic MMR defect were independently associated with lymph node metastasis after controlling for risk criteria. Epigenetic MMR deficiency was found to be an independent predictor of recurrence beyond the factors considered in traditional risk stratification algorithms. Traditional uterine-based risk stratification algorithms may not fully reflect the risk for recurrence in MMR deficient tumors. Consideration should be given to implementing MMR status and MLH1 hypermethylation alongside traditional risk stratification algorithms. Performing MMR IHC on preoperative pathologic specimens may aid in risk stratification and patient counseling.
RESUMO
OBJECTIVE: To examine patients with confirmed endometrial cancer recurrence; evaluate patterns, presentation, and mode of diagnosis. STUDY DESIGN: A retrospective review of women with endometrial cancer diagnosis between 2014 and 2020. Disease recurrences were evaluated. Medical records were reviewed focusing on presentation at time of recurrence. Relationships were assessed using χ2, Fisher's exact test, t-test, and Wilcoxon test. The Kaplan-Meier product limit was used to estimate survival. Multiple logistic regression analysis was used to assess the impact of covariates. RESULTS: Endometrial cancer recurrence was identified in 201 (11.7%) patients. Sixty percent (120/201) of patients presented with symptoms. Pain was the most common presenting symptom (23.4%, 47/201) and bleeding was reported in <14% (28/201). Patients with symptomatic presentation were less likely to be able to receive treatment for their recurrent disease (76.7% vs 91.3%, p = 0.005). Asymptomatic pelvic exam diagnosed recurrence in 13.4% (27/201) and was more common in patients initially diagnosed with early-stage disease (66.7% vs 34.5% p = 0.001) of endometrioid histology (66.7% vs 36.8%, p = 0.003) without prior adjuvant therapy (48.2% vs 17.9%, p = 0.001). More than1/3 of diagnoses were made by providers outside of the oncologic care team. CONCLUSION: The majority of women with recurrent endometrial cancer were symptomatic and pain is a common complaint associated with disease recurrence. Patients with symptomatic presentation of disease recurrence were less likely to receive treatment for recurrent disease but this did not result in an overall survival (OS) difference. Given the rising mortality rate of endometrial cancer further work is needed to develop multidisciplinary surveillance strategies that will enable meaningful treatment of disease recurrence.

BACKGROUND: Deviations from gestational weight gain (GWG) recommendations are associated with unfavorable maternal and neonatal outcomes. There is a need to understand how maternal substrate metabolism, independent of weight status, may contribute to GWG and neonatal outcomes. The purpose of this study was to explore the potential link between maternal lipid oxidation rate, GWG, and neonatal anthropometric outcomes. METHODS: Women (N = 32) with a lean pre-pregnancy BMI were recruited during late pregnancy and substrate metabolism was assessed using indirect calorimetry, before and after consumption of a high-fat meal. GWG was categorized as follows: inadequate, adequate, or excess. Shortly after delivery (within 48 h), neonatal anthropometrics were obtained. RESULTS: Using ANOVA, we found that fasting maternal lipid oxidation rate (grams/minute) was higher (p = 0.003) among women with excess GWG (0.1019 ± 0.0416) compared to women without excess GWG (inadequate = 0.0586 ± 0.0273, adequate = 0.0569 ± 0.0238). Findings were similar when lipid oxidation was assessed post-meal and also when expressed relative to kilograms of fat free mass. Absolute GWG was positively correlated to absolute lipid oxidation expressed in grams/minute at baseline (r = 0.507, p = 0.003), 2 h post-meal (r = 0.531, p = 0.002), and 4 h post-meal (r = 0.546, p = 0.001). Fasting and post-meal lipid oxidation (grams/minute) were positively correlated to neonatal birthweight (fasting r = 0.426, p = 0.015; 2-hour r = 0.393, p = 0.026; 4-hour r = 0.540, p = 0.001) and also to neonatal absolute fat mass (fasting r = 0.493, p = 0.004; 2-hour r = 0.450, p = 0.010; 4-hour r = 0.552, p = 0.001). CONCLUSIONS: A better understanding of the metabolic profile of women during pregnancy may be critical in truly understanding a woman's risk of GWG outside the recommendations. GWG counseling during prenatal care may need to be tailored to women based not just on their weight status, but other metabolic characteristics.

With the dramatic increase in the prevalence of obesity, there is a corresponding increase in surgical procedures to treat obesity. Reproductive aged women (18-45 years old) undergo half of the bariatric surgical procedures performed in the United States each year. These women experience profound physiologic changes in response to bariatric surgery, including dramatic changes in reproductive function. Current guidelines recommend delaying attempts at conception for 12-24 months after bariatric surgery during the time of most profound weight loss. Despite these recommendations, many women report unprotected intercourse during this time, and many use less efficacious contraceptive options. Herein, we address contraceptive considerations in women of reproductive age who undergo bariatric surgery and opportunities to maximize a multidisciplinary surgical approach to optimize their overall health.

OBJECTIVE: As a protective response, during starvation organisms withdraw energy from growth and reproduction to focus on cellular maintenance. Cancer cells cannot undergo this differential response which has been theorized as an adjunct to improve both the effect of chemotherapy treatment and reduce treatment side effects. We sought to investigate the feasibility and effect of short-term fasting in patients receiving chemotherapy for gynecologic malignancy. METHODS: A randomized control trial was conducted of women with gynecologic malignancies receiving at least 6 planned chemotherapy cycles. Fasting patients maintaining a water-only fast for 24 h before and 24 h following each chemotherapy cycle were compared to nonfasting patients. Treatment related side effects and quality of life (QOL) was assessed using NCCN-FACT FOSI-18 questionnaire. RESULTS: Analysis included data from 120 cycles of chemotherapy. The majority of patients had stage 3 and 4 malignancy requiring multi-agent chemotherapy. Eleven patients had ovarian, 8 had uterine, and 1 had cervical cancer. Ninety percent received taxane and platinum-based doublet therapy. Weight loss and unanticipated hospitalizations were similar between treatment groups. Fewer dose reductions or delays were seen in the fasting group. There was no significant difference in mean QOL scores, but fasting group QOL scores improved over the course of treatment to a level that reached the minimal clinically important difference. CONCLUSION: A 48-h fast is well tolerated without increasing weight loss, hospital admissions, or chemotherapy dose reduction/delays. Fasting resulted in fewer treatment modifications and improved quality of life scores over the course of treatment.
