RESUMEN
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.

Interleukin-1ß (IL-1ß) is an inflammatory cytokine that plays a prominent role in stress-induced behavioral changes. In a model of repeated social defeat (RSD), elevated IL-1ß expression in the brain was associated with recruitment of primed macrophages that were necessary for development of anxiety-like behavior. Moreover, microglia activation and anxiety-like behavior associated with RSD did not occur in IL-1 receptor type-1 knock-out (IL-1R1(KO)) mice. Therefore, the objective of this study was to examine the role of IL-1 signaling in RSD-induced macrophage trafficking to the brain and anxiety-like behavior. Initial studies revealed that RSD did not increase circulating myeloid cells in IL-1R1(KO) mice, resulting in limited macrophage trafficking to the brain. In addition, IL-1R1(KO) bone marrow-chimera mice showed that IL-1R1 expression was essential for macrophage trafficking into the brain. To differentiate cellular mediators of stress-induced IL-1 signaling, endothelial-specific IL-1R1 knock-down (eIL-1R1kd) mice were used. Both wild-type (WT) and eIL-1R1kd mice had increased circulating monocytes, recruitment of macrophages to the brain, and altered microglia activation after RSD. Nonetheless, RSD-induced expression of IL-1ß, TNF-α, and IL-6 mRNA in brain CD11b(+) cells was attenuated in eIL-1R1kd mice compared with WT. Moreover, anxiety-like behavior did not develop in eIL-1R1kd mice. Collectively, these findings demonstrated that there was limited RSD-induced priming of myeloid cells in IL-1R1(KO) mice and disrupted propagation of neuroinflammatory signals in the brain of eIL-1R1kd mice. Furthermore, these data showed that transduction of IL-1 signaling by endothelial cells potentiates stress-induced neuroinflammation and promotes anxiety-like behavior.

Prenatal stress (PNS) is associated with neuropsychiatric disorders in offspring, including anxiety, depression, and autism spectrum disorders. There is mounting evidence that these behavioral phenotypes have origins in utero. Maternal microbes, inflammation, and serotonergic dysfunction have been implicated as potential mediators of the behavioral consequences of PNS; whether and how these systems interact is unclear. Here, we examine the effects of PNS in utero using late-gestation maternal restraint stress in wild-type (WT), germ-free (GF), and CCL2-/- genetic knock-out (KO) mice. In WT mice, PNS leads to placental and fetal brain inflammation, including an elevation in the chemokine CCL2. This inflammation is largely absent in GF mice, indicating the critical role of maternal microbes in mediating immune processes in utero. Furthermore, PNS in the absence of CCL2 failed to increase pro-inflammatory cytokine IL-6 in the fetal brain. PNS offspring also exhibited deficits in sociability and anxiety-like behavior that were absent in CCL2-/- PNS offspring. Tryptophan and serotonin (5-HT) were elevated in the WT PNS placenta, but not in CCL2-/- and GF animals. Altogether, these findings suggest that a complex interaction between maternal microbes, inflammation, and serotonin metabolism regulates the emergence of behavioral abnormalities following PNS.

BACKGROUND: Neuroinflammatory signaling may contribute to the pathophysiology of chronic anxiety disorders. Previous work showed that repeated social defeat (RSD) in mice promoted stress-sensitization that was characterized by the recurrence of anxiety following subthreshold stress 24 days after RSD. Furthermore, splenectomy following RSD prevented the recurrence of anxiety in stress-sensitized mice. We hypothesize that the spleen of RSD-exposed mice became a reservoir of primed monocytes that were released following neuroendocrine activation by subthreshold stress. METHODS: Mice were subjected to subthreshold stress (i.e., single cycle of social defeat) 24 days after RSD, and immune and behavioral measures were taken. RESULTS: Subthreshold stress 24 days after RSD re-established anxiety-like behavior that was associated with egress of Ly6C(hi) monocytes from the spleen. Moreover, splenectomy before RSD blocked monocyte trafficking to the brain and prevented anxiety-like behavior following subthreshold stress. Splenectomy, however, had no effect on monocyte accumulation or anxiety when determined 14 hours after RSD. In addition, splenocytes cultured 24 days after RSD exhibited a primed inflammatory phenotype. Peripheral sympathetic inhibition before subthreshold stress blocked monocyte trafficking from the spleen to the brain and prevented the re-establishment of anxiety in RSD-sensitized mice. Last, ß-adrenergic antagonism also prevented splenic monocyte egress after acute stress. CONCLUSIONS: The spleen served as a unique reservoir of primed monocytes that were readily released following sympathetic activation by subthreshold stress that promoted the re-establishment of anxiety. Collectively, the long-term storage of primed monocytes in the spleen may have a profound influence on recurring anxiety disorders.
