Cancer cachexia is a multifactorial wasting syndrome associated with skeletal muscle and adipose tissue loss, as well as decreased appetite. It affects approximately half of all cancer patients and leads to a decrease in treatment efficacy, quality of life, and survival. The human microbiota has been implicated in the onset and propagation of cancer cachexia. Dysbiosis, or the imbalance of the microbial communities, may lead to chronic systemic inflammation and contribute to the clinical phenotype of cachexia. Though the relationship between the gut microbiome, inflammation, and cachexia has been previously studied, the oral microbiome remains largely unexplored. As the initial point of digestion, the oral microbiome plays an important role in regulating systemic health. Oral dysbiosis leads to the upregulation of pro-inflammatory cytokines and an imbalance in natural flora, which in turn may contribute to muscle wasting associated with cachexia. Reinstating this equilibrium with the use of prebiotics and probiotics has the potential to improve the quality of life for patients suffering from cancer-related cachexia.

Objectives: High-grade squamous lesions of the cervix, (Cervical Intraepithelial Neoplasia (CIN) grade 2 and 3), are concerning, common, and costly precancerous findings, particularly for safety net hospitals who provide healthcare regardless of finances or insurance status. Epidemiologic surveillance of these lesions is uncommon but might be useful to guide preventive interventions. We sought to estimate the prevalence of CIN 2/3 and its racial and ethnic distribution, accounting for patient’s clinical and sociodemographic characteristics. Methods: We used data from hospital and physician billing claims for any CIN diagnosis occurring at the Virginia Commonwealth University Health System (VCUHS) from 01/01/2016 through 12/31/2020, along with respective clinical and sociodemographic characteristics at the time of diagnosis. We estimated average adjusted prevalence of CIN 2/3 lesions by race and ethnicity, from average marginal effects, after selecting most relevant patient factors from a logistic regression (LR) using backward selection (removing terms with p ≥ 0.2 and adding those with p < 0.1). Results: There were 1,538 women diagnosed with CIN 1, 2, 3, and unspecified dysplasia of the cervix uteri with respective prevalence of 45%, 14%, 12%, and 30%. CIN2/3 prevalence (26%) varied by race and ethnicity: Asians (39%) > Latinas (32%) > Whites (28%) >Blacks (23%) > Other (20%). Of the variables included in the LR model (age, marital status, religion, preferred language, insurance status, Body Mass Index, HIV, HPV, presence of bacterial vaginosis, hypertension, cholesterol, diabetes, pulmonary conditions, arthritis, heart conditions, pregnancy status, parity, smoking, alcohol, and previous cancer diagnoses), only age, diabetes, pulmonary conditions, smoking, and heart disease remained in the final LR model. The estimated average adjusted prevalence of a CIN 2/3 diagnosis remained highest for Asian women (35%, 95%CI: 17-52%), followed by Latinx (28%, 95%CI: 19-37%), Whites (25%, 95%CI 22-29%), Blacks (23%, 95%CI: 20-27%), and other (18%, 95%CI: 9-26%). Conclusions: The higher CIN 2/3 prevalence estimates among Asian women relative to other races and ethnicities is unexpected, as it does not align with current distribution of cervical cancer diagnoses at VCUHS (only 3% Asian), nor with the patterns of cervical cancer incidence and mortality rates in Virginia and in the United States, where Asian women have the lowest incidence and mortality. However, it potentially suggests a higher rate of regression, a finding supported by at least one surveillance study with similar findings. Citation Format: Shreya R. Raman, Stephanie A.

Background: Although human papillomavirus vaccination and Papanicolaou screening have advanced cervical cancer prevention, high-grade squamous intraepithelial lesions (HSIL) remain common, particularly among individuals with metabolic comorbidities such as diabetes and hypercholesterolemia. Statins, commonly used for lipid control, possess anti-inflammatory and antiproliferative properties that may offer protective effects against cervical dysplasia. We explored the association between statin use and lesion grade in a population of patients with dysplasia and whether effects vary by comorbidity and race. Methods: Cross-sectional, observational retrospective analysis of electronic health records and billing data for 2,378 non-Latina/e (nL) Black (nLB) and nL White patients diagnosed with low-grade squamous intraepithelial lesions or HSIL between 2014 and 2021 at a large academic medical center. Logistic regression assessed associations between statin use, comorbidity profiles (diabetes, hypercholesterolemia), race, and HSIL versus low-grade squamous intraepithelial lesions, adjusting for potential confounders. Interaction terms were tested to evaluate effect modification. Results: Statin users had significantly lower odds of HSIL than nonusers (adjusted OR = 0.48, P < 0.0001), despite being older, and having higher comorbidity rates. Predicted HSIL probabilities ranged from 4% to 20% in statin users versus 13% to 29% in nonusers. The lowest risk was observed among patients with diabetes on statins, particularly among nLB patients, suggesting a possible synergistic protective effect in metabolically vulnerable populations. Only 35% of patients with a hypercholesterolemia diagnosis listed were on statins. Conclusions: Statin use was associated with substantially lower HSIL risk, particularly among nLB patients with diabetes. Impact: These findings support further investigation of statins as a potential low-cost chemopreventive tool for cervical dysplasia, especially in populations with metabolic dysfunction.
