HIV and intersectional stigma among people living with HIV and healthcare workers and antiretroviral therapy adherence in the Dominican Republic.

BACKGROUND: HIV-related stigma, discrimination, and social marginalization undermines optimal HIV care outcomes. More research examining the impact of HIV-related stigma, discrimination, other interlocking forms of oppression, and antiretroviral therapy (ART) adherence is needed to optimize HIV treatment programming. This study uses data from two clinics in the Dominican Republic to examine client and healthcare worker (HCW) perceptions of HIV and intersectional stigmas among people living with HIV. METHODS: Surveys exploring demographics, HIV-related stigma, various dimensions of discrimination (race/ethnicity, HIV status, sexual orientation), healthcare engagement, and medication adherence were collected from 148 clients and 131 HCWs. Analysis of variance was conducted to examine differences in stigma by clinic and logistic regressions were used to determine predictors of optimal client medication adherence. RESULTS: Perceived discrimination in healthcare facilities due to clients' sexual orientation retained significance in crude and multivariable logistic regression models and was negatively associated with ART adherence (aOR:0.79; 95% CI:0.66, 0.95). DISCUSSION: Findings highlight the importance of implementing strategies to address stigma, discrimination, and social marginalization, particularly within healthcare facilities.

A Moderated Mediation Analysis of HIV and Intersectional Stigmas and Antiretroviral Adherence in People Living with HIV in the Dominican Republic.

Experiencing HIV and intersectional stigmas in healthcare settings may affect antiretroviral treatment (ART) adherence among people with HIV (PWH), given their need for frequent interactions with clinical settings and healthcare providers. Considering the importance of reducing stigmas to promote well-being and the need to elucidate how stigma influences health across various settings, we examined how experienced HIV stigma in Dominican Republic healthcare settings impacts ART adherence through internalized HIV stigma and whether race or sexual orientation stigma moderates this relationship. Participants were 471 PWH (aged 17-71) who were recruited from two HIV clinics in the Dominican Republic in 2021-2022. Results revealed a significant mediation effect (B=-0.10, SE = 0.05, CI [-0.234, - 0.014]) after adjusting for effect of age and time since HIV diagnosis, suggesting that experienced HIV stigma in healthcare settings was associated with more internalized HIV stigma (B = 0.39, SE = 0.11, p = .001), subsequently linked to lower ART adherence (B=-0.26, SE = 0.11, p = .016). The indirect effect was significant at low levels of race stigma (B=-0.16, SE = 0.09, CI [-0.369, - 0.001]) but not at high levels of race stigma (B=-0.06, SE = 0.05, CI [-0.175, 0.038]). This indirect effect was also significant at low levels of sexual orientation stigma (B=-0.19, SE = 0.10, CI [-0.401, - 0.023]) but not at high levels of sexual orientation stigma (B=-0.04, SE = 0.06, CI [-0.160, 0.074]). These findings suggest that addressing experienced HIV stigma in Dominican Republic healthcare settings, along with various dimensions of HIV-related stigma (e.g., internalized stigma) and intersecting stigmas (e.g., race, sexual orientation), is vital for improving health outcomes, such as optimal ART adherence.

RESUMEN: Experimentar estigmas relacionados con el VIH e interseccionales en entornos de atención médica puede afectar la adherencia al tratamiento antirretroviral (TAR) entre las personas que viven con VIH (PVVIH), dado que necesitan interacciones frecuentes con entornos clínicos y proveedores de atención médica. Considerando la importancia de reducir los estigmas para promover el bienestar y la necesidad de esclarecer cómo el estigma influye en la salud en diversos contextos, examinamos cómo el estigma del VIH experimentado en entornos de atención médica en la República Dominicana impacta la adherencia al TAR a través del estigma internalizado del VIH y si el estigma racial o de orientación sexual modera esta relación. Los participantes fueron 471 PVVIH (de 17 a 71 años) que fueron reclutados de dos clínicas de VIH en la República Dominicana en 2021­2022. Los resultados revelaron un efecto de mediación significativo (B=-0.10, SE = 0.05, CI [-0.234, − 0.014]) después de ajustar por el efecto de la edad y el tiempo desde el diagnóstico de VIH, sugiriendo que el estigma del VIH experimentado en entornos de atención médica estaba asociado con un mayor estigma internalizado del VIH (B = 0.39, SE = 0.11, p = .001), vinculado posteriormente a una menor adherencia al TAR (B=-0.26, SE = 0.11, p = .016). El efecto indirecto fue significativo en niveles bajos de estigma racial (B=-0.16, SE = 0.09, CI [-0.369, − 0.001]) pero no en niveles altos de estigma racial (B=-0.06, SE = 0.05, CI [-0.175, 0.038]). Este efecto indirecto también fue significativo en niveles bajos de estigma por orientación sexual (B=-0.19, SE = 0.10, CI [-0.401, − 0.023]) pero no en niveles altos de estigma por orientación sexual (B=-0.04, SE = 0.06, CI [-0.160, 0.074]). Estos hallazgos sugieren que abordar el estigma del VIH experimentado en entornos de atención médica en la República Dominicana, junto con diversas dimensiones del estigma relacionado con el VIH (por ejemplo, estigma internalizado) y estigmas interseccionales (por ejemplo, raza, orientación sexual), es vital para mejorar los resultados de salud, como la adherencia óptima al TAR.

A rare case report of a primary lung cancer comprising adenocarcinoma and atypical carcinoid tumor, with the carcinoid component harboring EML4-ALK rearrangement.

Background: The occurrence of pulmonary adenocarcinoma coexisting with atypical carcinoid tumors is a rare phenomenon. The presence of EML4-ALK fusion in an atypical carcinoid component of a histologically mixed tumor is even more uncommon. Due to their infrequency, the origin and pathogenesis of these mixed tumors remain largely unknown. The advances of therapy development in such patients are still limited and there is no standard treatment. We present a case of collision tumor in the lung consisting of atypical carcinoid and adenocarcinoma to better understand the clinical characteristics of this disease. Case Description: We report an extremely rare case of EML4-ALK rearrangement in a pulmonary atypical carcinoid tumor that coexisting with adenocarcinoma. A 58-year-old woman, who was asymptomatic, underwent pulmonary lobectomy due to the detection of a gradually enlarging solitary pulmonary nodule in the right upper lung. Histological examination of the resected tumor revealed the presence of both atypical carcinoid (approximately 80%) and adenocarcinoma (approximately 20%) components. Metastases by the carcinoid component were observed in mediastinal lymph nodes (station 2R and 4R) and in the primary tumor. Anaplastic lymphoma kinase (ALK) rearrangement was detected in both the primary and metastatic lesions of the carcinoid tumor. Four cycles of chemotherapy with etoposide and carboplatin were dispensed after surgery. Conclusions: This is the first reported case of coexisting pulmonary adenocarcinoma and atypical carcinoid tumor with an ALK fusion only detected in the carcinoid component. The presence of ALK rearrangement in pulmonary carcinoid tumor is very uncommon, and there is currently no standard treatment for advanced stages. Therefore, comprehensive molecular testing, including ALK rearrangement analysis, should be recommended for mixed tumors exhibiting features of atypical carcinoid. ALK inhibitors could represent a potential treatment strategy for selected patients.

Travel surveillance uncovers dengue virus dynamics and introductions in the Caribbean.

Dengue is the most prevalent mosquito-borne viral disease in humans, and cases are continuing to rise globally. In particular, islands in the Caribbean have experienced more frequent outbreaks, and all four dengue virus (DENV) serotypes have been reported in the region, leading to hyperendemicity and increased rates of severe disease. However, there is significant variability regarding virus surveillance and reporting between islands, making it difficult to obtain an accurate understanding of the epidemiological patterns in the Caribbean. To investigate this, we used travel surveillance and genomic epidemiology to reconstruct outbreak dynamics, DENV serotype turnover, and patterns of spread within the region from 2009-2022. We uncovered two recent DENV-3 introductions from Asia, one of which resulted in a large outbreak in Cuba, which was previously under-reported. We also show that while outbreaks can be synchronized between islands, they are often caused by different serotypes. Our study highlights the importance of surveillance of infected travelers to provide a snapshot of local introductions and transmission in areas with limited local surveillance and suggests that the recent DENV-3 introductions may pose a major public health threat in the region.

North-south pathways, emerging variants, and high climate suitability characterize the recent spread of dengue virus serotypes 2 and 3 in the Dominican Republic.

We employ a multidisciplinary approach, integrating genomics and epidemiology, to uncover recent dengue virus transmission dynamics in the Dominican Republic. Our results highlight a previously unknown north-south transmission pathway within the country, with the co-circulation of multiple virus lineages. Additionally, we examine the historical climate data, revealing long-term trends towards higher theoretical potential for dengue transmission due to rising temperatures. These findings provide information for targeted interventions and resource allocation, informing as well towards preparedness strategies for public health agencies in mitigating climate and geo-related dengue risks.

Mental Health Professionals' Perception of Respect for Human Rights and Organizational Well-Being in Three Countries of South America.

The respect for human rights in mental health care services significantly contributes to organizational well-being and is evolving into an actual benchmark of quality standards. This study assesses the perception of the respect for human rights for users and staff, as well as organizational and job satisfaction among mental health professionals in three South American countries, through the well-being at work and respect for human rights (WWRR) questionnaire and assesses whether there are significant differences. Seven mental health facilities in Argentina, Colombia, and Peru were involved in this observational study. The sample comprised 310 mental health professionals. The three countries exhibited differences in WWRR, particularly in the staff's satisfaction with resources for care (η2 = 0.166) and staff's satisfaction with organizational aspects (η2 = 0.113). Colombia had the lowest scores in these factors but the highest in the perception of the respect for human rights for users and staff, although this difference did not reach a statistical significance. Despite the progress made in recent years towards coercion-free medical standards and an increased focus on mental health polices in Latin American countries, there is a need to enhance the quality standards of mental health services, recognizing the value that the respect for human rights holds for the organizational well-being of both mental health users and professionals.

Current and emerging strategies for the management of advanced/metastatic lung neuroendocrine tumors.

Pulmonary neuroendocrine tumors represent a spectrum of disease ranging from typical carcinoid tumors to small cell lung cancers. The incidence of low-grade pulmonary NETs has been increasing, leading to improved awareness and the need for more treatment options for this rare cancer. Somatostatin analogs continue to be the backbone of therapy and may be followed or accompanied by targeted therapy, chemotherapy, and immune therapy. The recent addition of peptide receptor radionuclide therapy (PRRT) to the treatment armamentarium of NETs has led to the development of targeted alpha therapy to overcome PRRT resistance and minimize off-target adverse effects. Herein, we aim to highlight current treatment options for patients with advanced low grade pulmonary NETs along with emerging therapies, sequencing of therapies, upcoming clinical trials, and the importance of a multidisciplinary team to improve patient outcomes.

Global health reciprocal innovation to address mental health and well-being: strategies used and lessons learnt.

Over the past two decades there have been major advances in the development of interventions promoting mental health and well-being in low- and middle-income countries (LMIC), including delivery of care by non-specialist providers, incorporation of mobile technologies and development of multilevel community-based interventions. Growing inequities in mental health have led to calls to adopt similar strategies in high-income countries (HIC), learning from LMIC. To overcome shared challenges, it is crucial for projects implementing these strategies in different global settings to learn from one another. Our objective was to examine cases in which mental health and well-being interventions originating in or conceived for LMIC were implemented in the USA. The cases included delivery of psychological interventions by non-specialists, HIV-related stigma reduction programmes, substance use mitigation strategies and interventions to promote parenting skills and family functioning. We summarise commonly used strategies, barriers, benefits and lessons learnt for the transfer of these innovative practices among LMIC and HIC. Common strategies included intervention delivery by non-specialists and use of digital modalities to facilitate training and increase reach. Common barriers included lack of reimbursement mechanisms for care delivered by non-specialists and resistance from professional societies. Despite US investigators' involvement in most of the original research in LMIC, only a few cases directly involved LMIC researchers in US implementation. In order to achieve greater equity in global mental health and well-being, more efforts and targeted funding are needed to develop best practices for global health reciprocal innovation and iterative learning in HIC and LMIC.

Identification and Characterization of Avoidable Hospital Admissions in Patients With Lung Cancer.

BACKGROUND: More than 50% of patients with lung cancer are admitted to the hospital while receiving treatment, which is a burden to patients and the healthcare system. This study characterizes the risk factors and outcomes of patients with lung cancer who were admitted to the hospital. METHODS: A multidisciplinary oncology care team conducted a retrospective medical record review of patients with lung cancer admitted in 2018. Demographics, disease and admission characteristics, and end-of-life care utilization were recorded. Following a multidisciplinary consensus review process, admissions were determined to be either "avoidable" or "unavoidable." Generalized estimating equation logistic regression models assessed risks and outcomes associated with avoidable admissions. RESULTS: In all, 319 admissions for 188 patients with a median age of 66 years (IQR, 59-74 years) were included. Cancer-related symptoms accounted for 65% of hospitalizations. Common causes of unavoidable hospitalizations were unexpected disease progression causing symptoms, chronic obstructive pulmonary disease exacerbation, and infection. Of the 47 hospitalizations identified as avoidable (15%), the median overall survival was 1.6 months compared with 9.7 months (hazard ratio, 2.07; 95% CI, 1.34-3.19; P<.001) for unavoidable hospitalizations. Significant reasons for avoidable admissions included cancer-related pain (P=.02), hypervolemia (P=.03), patient desire to initiate hospice services (P=.01), and errors in medication reconciliation or distribution (P<.001). Errors in medication management caused 26% of the avoidable hospitalizations. Of admissions in patients receiving immunotherapy (n=102) or targeted therapy (n=44), 9% were due to adverse effects of treatment. Patients receiving immunotherapy and targeted therapy were at similar risk of avoidable hospitalizations compared with patients not receiving treatment (P=.3 and P=.1, respectively). CONCLUSIONS: We found that 15% of hospitalizations among patients with lung cancer were potentially avoidable. Uncontrolled symptoms, delayed implementation of end-of-life care, and errors in medication reconciliation were associated with avoidable inpatient admissions. Symptom management tools, palliative care integration, and medication reconciliations may mitigate hospitalization risk.

Genomic Surveillance of SARS-CoV-2 Variants in the Dominican Republic and Emergence of a Local Lineage.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an RNA virus that evolves over time, leading to new variants. In the current study, we assessed the genomic epidemiology of SARS-CoV-2 in the Dominican Republic. A total of 1149 SARS-CoV-2 complete genome nucleotide sequences from samples collected between March 2020 and mid-February 2022 in the Dominican Republic were obtained from the Global Initiative on Sharing All Influenza Data (GISAID) database. Phylogenetic relationships and evolution rates were analyzed using the maximum likelihood method and the Bayesian Markov chain Monte Carlo (MCMC) approach. The genotyping details (lineages) were obtained using the Pangolin web application. In addition, the web tools Coronapp, and Genome Detective Viral Tools, among others, were used to monitor epidemiological characteristics. Our results show that the most frequent non-synonymous mutation over the study period was D614G. Of the 1149 samples, 870 (75.74%) were classified into 8 relevant variants according to Pangolin/Scorpio. The first Variants Being Monitored (VBM) were detected in December 2020. Meanwhile, in 2021, the variants of concern Delta and Omicron were identified. The mean mutation rate was estimated to be 1.5523 × 10-3 (95% HPD: 1.2358 × 10-3, 1.8635 × 10-3) nucleotide substitutions per site. We also report the emergence of an autochthonous SARS-CoV-2 lineage, B.1.575.2, that circulated from October 2021 to January 2022, in co-circulation with the variants of concern Delta and Omicron. The impact of B.1.575.2 in the Dominican Republic was minimal, but it then expanded rapidly in Spain. A better understanding of viral evolution and genomic surveillance data will help to inform strategies to mitigate the impact on public health.

Health care access and migration experiences among Venezuelan female sex workers living in the Dominican Republic.

Objective: To identify sexual risk behaviors and barriers to sexual and reproductive health care (SRH) among Venezuelan female sex workers living in the Dominican Republic. Methods: This was a mixed-methods study using four focus group discussions (FGDs) and a cross-sectional quantitative survey with Venezuelan migrant female sex workers. The study was conducted from September through October 2021 in two urban areas (Santo Domingo and Puerto Plata) in the Dominican Republic. Information collected from the FGDs was analyzed using thematic content analysis, and quantitative data were analyzed using univariate descriptive statistics. Data analysis was conducted from 30 November 2021 to 20 February 2022. Results: In all, 40 Venezuelan migrant female sex workers with a median (range) age of 33 (19-49) years participated in the FGDs and survey. The FDGs identified barriers to SRH services, including immigration status and its implications for formal employment and health access, mental wellbeing, quality-of-life in the Dominican Republic, navigating sex work, perceptions of sex work, SRH knowledge, and limited social support. Findings of the quantitative analysis indicated that most participants reported feeling depressed (78%), lonely/isolated (75%), and having difficulty sleeping (88%). Participants reported an average of 10 sexual partners in the past 30 days; 55% had engaged in sexual practices while under the influence of alcohol; and only 39% had used a condom when performing oral sex in the past 30 days. Regarding AIDS/HIV, 79% had taken an HIV test in the past 6 months, and 74% knew where to seek HIV services. Conclusions: This mixed-methods study found that nationality and social exclusion have a multilayered influence on migrant female sex workers, sexual risk behaviors, and access to health care. Recommendations for effective evidence-based interventions to address sexual health knowledge need to be implemented to address risky sexual behaviors, improve access to SRH, and reduce affordability barriers.

[RESUMEN]. Objetivo. Determinar los comportamientos sexuales de riesgo y los obstáculos para acceder a los servi- cios de salud sexual y reproductiva (SSR) en trabajadoras sexuales venezolanas residentes en República Dominicana. Métodos: En este estudio se empleó una metodología mixta con cuatro debates en grupos de opinión y una encuesta cuantitativa transversal en trabajadoras sexuales migrantes venezolanas. El estudio se llevó a cabo entre septiembre y octubre del 2021 en dos zonas urbanas (Puerto Plata y Santo Domingo) de República Dominicana. La información recopilada a partir de los grupos de opinión se analizó mediante análisis de contenido temático, y los datos cuantitativos se analizaron mediante estadísticas descriptivas univariadas. El análisis de los datos se realizó del 30 de noviembre del 2021 al 20 de febrero del 2022. Resultados: Un total de 40 trabajadoras sexuales migrantes venezolanas con una mediana (rango) de edad de 33 años (entre 19 y 49) participaron en los grupos de opinión y la encuesta. Los grupos de opinión per- mitieron determinar los obstáculos para acceder a los servicios de SSR, como la situación migratoria y sus implicaciones para el acceso al empleo formal y a los servicios de salud, el bienestar mental, la calidad de vida en República Dominicana, el trabajo sexual y la manera de transitarlo, las percepciones sobre el trabajo sexual, los conocimientos sobre la SSR y el escaso apoyo social. Los resultados del análisis cuantitativo indi- caron que la mayoría de las participantes manifestaron que se sentían deprimidas (78%), solas o aisladas (75%), y que tenían dificultades para dormir (88%). Las participantes también indicaron que habían tenido un promedio de 10 parejas sexuales en los últimos 30 días, el 55% había mantenido relaciones sexuales bajo los efectos del alcohol y solo el 39% había utilizado preservativo al practicar sexo oral en los últimos 30 días. En cuanto a la infección por el VIH/sida, el 79% se había sometido a una prueba del VIH en los últimos 6 meses y el 74% sabía dónde buscar servicios relacionados con el VIH. Conclusiones. En este estudio basado en metodologías mixtas, se observó que la nacionalidad y la exclusión social afectan de diversas formas a las trabajadoras sexuales inmigrantes, sus comportamientos sexuales de riesgo y su acceso a la atención de salud. Es necesario poner en práctica las recomendaciones para la realización de intervenciones eficaces basadas en la evidencia para atender los conocimientos sobre salud sexual con el fin de abordar los comportamientos sexuales de riesgo, mejorar el acceso a la SSR y reducir los obstáculos relacionados con la asequibilidad.

Efficacy and toxicity of anti-vascular endothelial growth receptor tyrosine kinase inhibitors in patients with neuroendocrine tumours - A systematic review and meta-analysis.

AIM: Although anti-vascular endothelial growth factor (VEGF) receptor tyrosine kinase inhibitors (RTKIs) have been tested in patients with neuroendocrine tumours (NETs) over the last two decades, no study to date has benchmarked efficacy and toxicity of these drugs in this patient population. METHODS: All phase II and phase III studies of anti-VEGF RTKIs in patients with NETs, published between January 1, 2000 andJuly 31, 2021, across major trial databases, were searched in August 2021 for relevant studies. The primary objectives of the meta-analysis were to compare objective response rate (ORR) and progression-free survival (PFS) between patients with pancreatic NETs (pNETs) and extra-pancreatic NETs (epNETs), and the incidence rate ratio (IRR) of adverse events between patients receiving anti-VEGF RTKIs and control. RESULTS: 1611 patients were available for the meta-analysis; 1194 received anti-VEGF RTKIs. ORR in pNETs was 18% (95% confidence interval (CI) 13-25%), while ORR in epNETs was 8% (95% CI 5-12%); test for differences between pNETs and epNETs (x12 = 8.38, p < .01). Median PFS in pNETs was 13.9 months (95% CI 11.43-16.38 months), while median PFS in epNETs was 12.71 months (95% CI 9.37-16.05 months); test for differences between pNETs and epNETs (x12 = .35, p = .55). With regards to common grade 3/4 adverse events , patients who received anti-VEGF RTKIs were more likely to experience hypertension (IRR 3.04, 95% CI 1.63-5.65) and proteinuria (IRR 5.79, 95% CI 1.09-30.74) in comparison to those who received control. CONCLUSIONS: Anti-VEGF RTKIs demonstrate anti-tumour effect in both pNETs and epNETs, supporting their development in both populations. These agents also appear to be safe in patients with NETs.

Evaluation of sample pooling for the detection of SARS-CoV-2 in a resource-limited setting, Dominican Republic.

INTRODUCTION: COVID-19 is a worldwide public health threat. Diagnosis by RT-PCR has been employed as the standard method to confirm viral infection. Sample pooling testing can optimize the resources by reducing the workload and reagents shortage, and be useful in laboratories and countries with limited resources. This study aims to evaluate SARS-CoV-2 detection by sample pooling testing in comparison with individual sample testing. MATERIALS AND METHODS: We created 210 pools out of 245 samples, varying from 4 to 10 samples per pool, each containing a positive sample. We conducted detection of SARS-CoV-2-specific RdRp/E target sites. RESULTS: Pooling of three samples for SARS-CoV-2 detection might be an efficient strategy to perform without losing RT-PCR sensitivity. CONCLUSIONS: Considering the positivity rate in Dominican Republic and that larger sample pools have higher probabilities of obtaining false negative results, the optimal sample size to perform a pooling strategy shall be three samples.

Resultados: La combinación de hasta 3 muestras para la detección del SARS-CoV-2 podría ser una estrategia eficaz sin perder la sensibilidad. Conclusiones: Considerando la tasa de positividad en República Dominicana y que los grupos con más muestras tienen mayor probabilidad de obtener resultados falsos negativos, el tamaño óptimo para realizar esta estrategia es de 3 muestras.

Genome Sequence of a Recombinant SARS-CoV-2 Lineage XAM (BA.1.1/BA.2.9) Strain from a Clinical Sample in Santo Domingo, Dominican Republic.

Here, we report a recombinant severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) lineage XAM (Omicron BA.1.1/BA.2.9) strain that was collected in Santo Domingo, Dominican Republic. This demonstrates how SARS-CoV-2 variants can vary greatly between regions and thus underlines the great importance of regional genomic surveillance efforts.

Comparison of clinicopathological features and survival analysis between esophageal neuroendocrine carcinoma and esophageal squamous cell carcinoma based on the SEER database, alongside nomogram analysis for esophageal neuroendocrine carcinoma.

Background: Esophageal neuroendocrine carcinoma (ENEC) is a rare subtype of esophageal cancer (EC). It presents distinctive clinical and pathological features in comparison to esophageal squamous cell carcinoma (ESCC). To better elucidate the disparities between the two and establish a prognostic prediction model for ENEC, we conducted this study. Methods: Data of ENEC and ESCC patients (1975 to 2016) were extracted from the Surveillance, Epidemiology and End Results (SEER) database. Patients with a confirmed pathological diagnosis of ENEC and ESCC were enrolled in the study. The Chi-square test was employed to compare categorical variables, and the median survival time was analyzed using the Kaplan-Meier curve. Training and validation groups were randomly assigned at a ratio of 7:3. Factors with a significance level of <0.05 in the multifactor regression model as well as age were integrated into the nomogram model. Concordance index (C-index), calibration curves, and decision curve analyses (DCA) were generated for model validation. Results: This study encompassed a total of 737 ENEC patients and 29,420 ESCC. Compared to ESCC, ENEC patients had higher probability of liver metastasis (13.8% vs. 1.9%, P<0.001), poor differentiation (68.0% vs. 37.1%, P<0.001), and late SEER stage (52.8% vs. 26.9%, P<0.001). Patients who received either surgery, radiotherapy (RT), or chemotherapy had a significantly longer disease-specific survival (DSS) and overall survival (OS) (all P<0.001). After propensity score matching (PSM), ENEC patients were associated with shorter DSS (7.0 months vs. not reached, P<0.0001) and OS (7.0 vs. 12.0 months, P<0.0001) compared to ESCC. Race, SEER stage, surgery, RT, and chemotherapy were identified as predictors of DSS and were incorporated into the nomogram model together with age. The validation of the model using C-index (0.751 and 0.706, respectively) and calibration curves reflected the better discrimination power of the model. In addition, DCA supported the favorable potential clinical effect of the predictive model. Lastly, a risk classification based on the nomogram also verified the reliability of the model. Conclusions: ENEC and ESCC exhibit distinct clinicopathological features. Patients with ENEC experience significantly poorer survival outcomes compared to those with ESCC. Surgical intervention, radiation therapy, and chemotherapy significantly improve OS and DSS for ENEC patients. The nomogram prediction model, constructed based on age, race, stage, and treatment regimen, demonstrates accurate and effective predictive capabilities for prognostic factors in ENEC patients.
