Cytomegalovirus Post-Prophylaxis Surveillance in High-Risk Kidney and Liver Recipients Prevents CMV End-Organ Disease and Ganciclovir-Resistance.

PURPOSE: Evaluate cytomegalovirus (CMV) post-prophylaxis surveillance in high-risk (D+/R-) kidney and liver transplant recipients. METHODS: Adult D+/R- patients were included if transplanted between 6/1/15 and 11/30/22 and divided into a pre-CMV-stewardship-era (6/1/15-5/31/18), CMV-stewardship-era (6/1/18-6/30/20), and a surveillance-era (7/1/2020-11/30/2022) then followed through 12 months. The primary objective was to evaluate CMV-related outcomes. The secondary objective was to assess graft and patient survival by era. RESULTS: There were 328 patients in the study period; 133 in the pre-stewardship-era, 103 in the stewardship-era, and 92 in the surveillance-era. Replication rates in the surveillance-era were significantly higher, as anticipated due to increased sampling (pre 38.4%, stewardship 33.0%, surveillance 52.2%, p = 0.02). Time from transplant to first replication was similar (pre 214.0 ± 79.0 days, stewardship 231.1 ± 65.5, surveillance 234.9 ± 61.4, p = 0.29). CMV viral load (VL) at first detection, maximum-VL, and incidence of VL > 100 000 IU/mL were numerically lower in the surveillance era, although not statistically significant. CMV end-organ disease (p < 0.0001) and ganciclovir-resistance (p = 0.002) were significantly lower in the surveillance era than in both previous eras. Rejection was not different between eras (p = 0.4). Graft (p = 0.0007) and patient survival (p = 0.008) were significantly improved in the surveillance era. CONCLUSIONS: Post-prophylaxis surveillance significantly reduced CMV end-organ disease and resistance. Despite observing increased replication rates in the surveillance era, rejection was not significantly different and there was no graft loss or patient mortality at 12 months.

Risk and Reward: Nationwide Analysis of Cardiac Transplant Center Variation in Organ Travel Distance and the Effects on Outcomes.

BACKGROUND: The 2018 UNOS allocation policy change deprioritized geographic boundaries to organ distribution, and the effects of this change have been widespread. The aim of this investigation was to analyze changes in donor transplant center distance for organ travel and corresponding outcomes before and after the allocation policy change. METHODS: The UNOS database was utilized to identify all adult patients waitlisted for heart transplants from 2016 to 2021. Transplant centers were grouped by average donor heart travel distance based on whether they received more or less than 50% of organs from >250 miles away. Descriptive statistics were provided for waitlisted and transplanted patients. Regression analyses modeled waitlist mortality, incidence of transplant, overall survival, and graft survival. RESULTS: Centers with a longer average travel distance had a higher mean annual transplant volume with a reduction in total days on a waitlist (86.6 vs. 149.2 days), an increased cold ischemic time (3.6 vs. 3.2 h), with no significant difference in post-transplant overall survival or graft survival. CONCLUSIONS: The benefits of reducing waitlist time while preserving post-transplant outcomes extend broadly. The trends observed in this investigation will be useful as we revise organ transplant policy in the era of new organ procurement and preservation techniques.

Efficacy and safety of cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy in patients with pancreatic cancer peritoneal metastasis.

OBJECTIVES: Pancreatic cancer with peritoneal metastasis presents a challenging prognosis, with limited effective treatment options available. This study aims to evaluate the efficacy and safety of combining cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) as a treatment strategy for this patient group. METHODS: A retrospective analysis was conducted on patients with peritoneal metastasis of pancreatic cancer who underwent CRS + HIPEC treatment at Beijing Shijitan Hospital from March 2017 to December 2023. The study focused on assessing clinical features, the incidence of sever adverse events (SAEs), and overall survival (OS). RESULTS: A total of 10 patients were enrolled in this study. The median OS was 24.2 months, suggesting an improvement over traditional therapies. While SAEs were noted, including two cases of severe complications necessitating additional surgical interventions, no perioperative fatalities were recorded. The overall survival time for patients with CC0/1 was not significantly different from that of patients with CC2/3, and no prognostic predictors were identified. CONCLUSIONS: The combination of CRS and HIPEC appears to be a viable and promising treatment modality for patients with peritoneal metastasis of pancreatic cancer, offering an improved survival rate with manageable safety concerns. Further research is needed to refine patient selection criteria and to explore the long-term benefits of this approach.

The role of local ablative therapy in patients with advanced invasive mucinous adenocarcinoma of the lung.

PURPOSE: Invasive mucinous adenocarcinoma (IMA) of the lungs is a rare subtype of lung adenocarcinoma with a limited understanding of its prognosis, particularly in advanced stages. This study aimed to assess the prognosis of patients with advanced IMA by focusing on treatment modalities. METHODS: This single-center retrospective study evaluated 33 patients with IMAs diagnosed with advanced-stage disease or disease progression after curative treatment between 2011 and 2021. The primary outcome was overall survival (OS), and the secondary outcome was progression-free survival (PFS). OS and PFS were calculated from the date of the diagnosis of advanced IMA. RESULTS: The study cohort included 13 patients at the initial advanced stage and 20 patients who progressed after curative treatment. Treatment modalities included conventional chemotherapy in 24 patients (72.7%), targeted therapy in seven (21.2%), immunotherapy in 13 (39.4%), and local ablative therapy (LAT) in 13 (39.4%). The median OS was 32 months (95% confidence interval [CI], 2.9-61.0), with LAT significantly associated with improved OS compared to non-LAT treatment (not reached vs. 11.3 months, p = 0.001). However, there was no significant difference in OS based on conventional chemotherapy (p = 0.396), targeted therapy (p = 0.655), or immunotherapy (p = 0.992). In multivariate analysis, LAT remained an independent prognostic factor for OS (hazard ratio, 0.125; 95% CI, 0.026-0.608; p = 0.01). PFS was 8.6 months (95% CI, 3.6-13.7), with no significant differences observed among the treatment modalities. CONCLUSION: Our findings suggest that LAT may provide favorable survival outcomes in patients with advanced IMA.

Impact of Donor-Recipient BMI Ratio on Survival Outcomes of Heart Transplant Recipients: A Retrospective Analysis Study.

OBJECTIVE: This study aimed to investigate the impact of the donor-recipient BMI ratio on the survival outcomes of heart transplant recipients. METHODS: A retrospective analysis was conducted on 641 heart transplant patients who underwent surgery between September 2008 and June 2021. The BMI ratio (donor BMI divided by recipient BMI) was calculated for each patient. Kaplan-Meier survival analysis and Cox proportional hazards regression were performed to evaluate survival rates and determine the hazard ratio (HR) for mortality. RESULTS: Significant differences were found in donor age and donor-recipient height ratio between the BMI ratio groups. The BMI ratio ≥ 1 group had a higher mean donor age (37.27 ± 10.54 years) compared to the BMI ratio < 1 group (34.72 ± 11.82 years, p = 0.008), and a slightly higher mean donor-recipient height ratio (1.02 ± 0.06 vs. 1.00 ± 0.05, p = 0.002). The Kaplan-Meier survival analysis indicated that the survival rate in the BMI ratio ≥ 1 group was significantly lower than in the BMI ratio < 1 group. Cox multivariate analysis, adjusted for confounding factors, revealed a HR of 1.50 (95% CI: 1.08-2.09) for mortality in patients with a BMI ratio ≥ 1. No significant differences were observed in ICU stay, postoperative hospitalization days, or total mechanical ventilation time between the groups. CONCLUSION: A higher donor-recipient BMI ratio was associated with an increased risk of mortality in heart transplant recipients.

Catheter and Non-Catheter-Related Venous Thromboembolism in Cancer Patients: Survival, Anticoagulation Efficacy, and Safety.

PURPOSE: To investigate the differences in survival after venous thromboembolism (VTE) and anticoagulation efficacy and safety between catheter (CRVTE) and non-catheter-related VTE (NCRVTE) in cancer patients. METHODS: A retrospective research was conducted, and consecutive cancer (digestive, respiratory, genitourinary, blood and lymphatic, and the other cancers) patients with VTE were enrolled. The anticoagulation therapies included low-molecular-weight heparin (LMWH), warfarin, new type of direct oral anticoagulants (NDOACs), LMWH combined with warfarin, and LMWH combined with NDOACs. Data were collected from the electronic medical record database of our hospital and were analyzed accordingly by Kruskal-Wallis H Test, Chi-square test, Fisher's exact test, Logistic regressions, Kaplan-Meier analysis, and Cox regressions. RESULTS: 263 patients were included, median age in years (interquartile range) was 64(56-71) and 60.5% were male. VTE recurrence rate was 16.7% in CRVTE group which was significantly lower than 34.8% in NCRVTE group (P = .032). Heart diseases were independently associated with VTE recurrence (P = .025). Kaplan-Meier survival estimates at 1, 2, and 3 years for CRVTE group were 62.5%, 60.0%, and 47.5%, respectively, compared with 47.9% (P = .130), 38.7% (P = .028), and 30.1% (P = .046), respectively, for NCRVTE group. Cox regression showed surgery (P = .003), anticoagulation therapy types (P = .009), VTE types (P = .006) and cancer types (P = .039) were independent prognostic factors for 3-year survival after VTE. Nonmajor and major bleeding were not significantly different (P = .417). Anticoagulation therapy types were independently associated with the bleeding events (P = .030). CONCLUSIONS: Cancer patients with CRVTE potentially have a better anticoagulation efficacy and survival compared to NCRVTE, and the anticoagulation safety seems no significant difference.

Comparative analysis of breast and lung cancer survival rates and clinical trial enrollments among rural and urban patients in Georgia.

Objectives: Rural patients have poor cancer outcomes and clinical trial (CT) enrollment compared to urban patients due to attitudinal, awareness, and healthcare access differential. Knowledge of cancer survival disparities and CT enrollment is important for designing interventions and innovative approaches to address the stated barriers. The study explores the potential disparities in cancer survival rates and clinical trial enrollments in rural and urban breast and lung cancer patients. Our hypotheses are that for both cancer types, urban cancer patients will have longer 5-year survival rates and higher enrollment rates in clinical trials than those in rural counties. Methods: We compared breast and lung cancer patients' survival rates and enrollment ratios in clinical trials between rural (RUCC 4-9) and urban counties in Georgia at a Comprehensive Cancer Center (CCC). To assess these differences, we carried out a series of independent samples t-tests and Chi-Square tests. Results: The outcomes indicate comparable 5-year survival rates across rural and urban counties for breast and lung cancer patients, failing to substantiate our hypothesis. While clinical trial enrollment rates demonstrated a significant difference between breast and lung cancer patients at CCC, no significant variation was observed based on rural or urban classification. Conclusion: These findings underscore the need for further research into the representation of rural patients with diverse cancer types at CCC and other cancer centers. Further, the findings have considerable implications for the initiation of positive social change to improve CT participation and reduce cancer survival disparities.

Construction of a new tool for predicting cancer-specific survival in papillary thyroid cancer patients who have not received surgery.

Background: The prevalence of papillary thyroid cancer is gradually increasing and the trend of youthfulness is obvious. Some patients may not be able to undergo surgery, which is the mainstay of treatment, due to physical or financial reasons. Therefore, the prediction of cancer-specific survival (CSS) in patients with non-operated papillary thyroid cancer is necessary. Methods: Patients' demographic and clinical information was extracted from the Surveillance, Epidemiology, and End Results database. SPSS software was used to perform Cox regression analyses as well as propensity score matching analyses. R software was used to construct and validate the nomogram. X-tile software was used to select the best cutoff point for patient risk stratification. Results: A total of 1319 patients were included in this retrospective study. After Cox regression analysis, age, grade, T stage, M stage, radiotherapy, and chemotherapy were used to construct the nomogram. C-index, calibration curves, and receiver operating characteristic curves all verified the high predictive accuracy of the nomogram. The decision curve analysis demonstrated that patients could gain clinical benefit from this predictive model. Survival curve analysis after propensity score matching demonstrated the positive effects of radiotherapy on CSS in non-operated patients. Conclusion: Our retrospective study successfully established a nomogram that accurately predicts CSS in patients with non-operated papillary thyroid cancer and demonstrated that radiotherapy for operated patients can still help improve prognosis. These findings can help clinicians make better choices.

Strategy and Outcomes of Cardiac Surgery in Patients With Cirrhosis: Comprehensive Approach With Liver Transplant Program.

BACKGROUND: Cardiac surgery is considered a contraindication in patients with advanced liver cirrhosis (LC) due to increased mortality and morbidity. There are limited data on the treatment strategy and management of this population. We aimed to present our strategy and evaluate the clinical outcome of cardiac surgery in patients with LC. METHODS: Our strategy was (i) to list patients for liver transplant (LT) at the time of cardiac surgery; (ii) to maintain high cardiopulmonary bypass (CPB) flow (index up to 3.0 L/min/m2) based on hyper-dynamic states due to LC; and (iii) to proceed to LT if patients' liver function deteriorated with an increasing model for end-stage liver disease Na (MELD-Na) score after cardiac surgery. Thirteen patients (12 male and 1 female [mean age, 63.0]) with LC who underwent cardiac surgery between 2017 and 2024 were retrospectively analyzed. RESULTS: Six patients were listed for LT. Indications for cardiac surgery included coronary artery disease (N = 7), endocarditis (N = 2), and tricuspid regurgitation (N = 1), tricuspid stenosis (N = 1), mitral regurgitation (N = 1), and hypertrophic obstructive cardiomyopathy (N = 1). The Child-Pugh score was A in five, B in six, and C in one patient. The procedure included coronary artery bypass grafting (N = 6), single valve surgery (mitral valve [N = 2] and tricuspid valve [N = 1]), concomitant aortic and tricuspid valve surgery (N = 2), and septal myectomy (N = 1). Two patients had a history of previous sternotomy. The perfusion index during CPB was 3.1 ± 0.5 L/min/m2. Postoperative complications include pleural effusion (N = 6), bleeding events (N = 3), acute kidney injury (N = 1), respiratory failure requiring tracheostomy (N = 2), tamponade (N = 1), and sternal infection (N = 1). There was no in-hospital death. There was one remote death due to COVID-19 complication. Preoperative and postoperative highest MELD-Na score among listed patients was 15.8 ± 5.1 and 19.3 ± 5.3, respectively. Five patients underwent LT (1, 5, 8, 16, and 24 months following cardiac surgery) and one patient remains on the list. Survival rates at 1 and 3 years are 100% and 75.0%, respectively. CONCLUSION: Cardiac surgery maintaining high CPB flow with LT backup is a feasible strategy in an otherwise inoperable patient population with an acceptable early and midterm survival when performed in a center with an experienced cardiac surgery and LT program.

Procurement Trends, Indications, and Outcomes of Heart-Lung Transplantation in the Contemporary Era.

BACKGROUND: Evolving trends in organ procurement and technological innovation prompted an investigation into recent trends, indications, and outcomes following combined heart-lung transplantation (HLTx). METHODS: The United Network for Organ Sharing database was queried for all adult (≥18 years) HLTx performed between July 1, 2013 and June 30, 2023. Patients with previous transplants were excluded. The primary endpoint was the effect of donor, recipient, and transplantation characteristics on 1- and 5-year survival. Secondary analyses included a comparison of HLTx at high- and low-volume centers, an assessment of HLTx following donation after circulatory death (DCD), and an evaluation of HLTx volume over time. Cox proportional-hazards models were used to assess factors associated with mortality. Temporal trends were evaluated with linear regression. RESULTS: After exclusions, 319 patients were analyzed, of whom 5 (1.6%) were DCD. HLTx volume increased from 2013 to 2023 (p < 0.001). One- and 5-year survival following HLTx was 84.0% and 59.5%, respectively. One-year survival was higher for patients undergoing HLTx at a high-volume center (88.3% vs. 77.9%; p = 0.012). After risk adjustment, extracorporeal membrane oxygenation support 72 h posttransplant and predischarge dialysis were associated with increased 1-year mortality (HR = 3.19, 95% CI = 1.86-5.49 and HR = 3.47, 95% CI = 2.17-5.54, respectively) and 5-year mortality (HR = 2.901, 95% CI = 1.679-5.011 and HR = 3.327, 95% CI = 2.085-5.311, respectively), but HLTx at a high-volume center was not associated with either. CONCLUSIONS: HLTx volume has resurged, with DCD HLTx emerging as a viable procurement strategy. Factors associated with 1- and 5-year survival may be used to guide postoperative management following HLTx.

The impact of postoperative adjuvant therapy on EGFR-mutated stage IA lung adenocarcinoma with micropapillary pathological subtypes.

BACKGROUND: Micropapillary (MPP) adenocarcinoma is considered one of the most aggressive pathological types of lung adenocarcinoma (LADC). This retrospective study aimed to evaluate the prognostic significance and benefit of postoperative adjuvant therapy (PAT) in stage IA LADC patients with different proportions of MPP components. MATERIALS AND METHODS: We retrospectively examined clinical stage IA LADC patients who underwent surgical resection between August 2012 and December 2019. In terms of the proportion of MPP components (TPM), the tumors were reclassified into three categories: MPP patterns absent (TPMN); low proportions of MPP components (TPML); and high proportions of MPP components (TPMH). The dates of recurrence and metastasis were identified based on physical examinations and were confirmed by histopathological examination. RESULTS: Overall, 505 (TPMN, n = 375; TPML, n = 92; TPMH, n = 38) patients harboring EGFR mutations were enrolled in the study. Male sex (P = 0.044), high pathological stage (P < 0.001), and MPP pathological subtype (P < 0.001) were more frequent in the TPM-positive (TPMP) group than in the TPM-negative (TPMN) group. Five-year disease-free survival (DFS) rates were significantly lower in the TPMP group than in the TPMN group (84.5% vs. 93.4%, P = 0.006). In addition, patients with high proportions (greater than 10%) of MPP components had worse overall survival (OS) (91.0% vs. 98.9%, P = 0.025) than those with low proportions (5%≤ TPM ≤ 10%). However, postoperative EGFR tyrosine kinase inhibitors (TKIs) or adjuvant chemotherapy (ACT) cannot improve DFS and OS between EGFR-mutated patients with different proportions of MPP components. CONCLUSION: MPP was related to earlier recurrence and shortened survival time, even in stage IA. Further research needs a larger sample size to clarify that EGFR-mutated stage IA patients with MPP components obtain survival benefits from adjuvant therapy.

Trends of primary liver cancer incidence and mortality in the United States: A population-based study over the last four decades.

BACKGROUND: Primary liver cancer is the third leading cause of cancer deaths worldwide and has one of the worst 5-year survival rates. This study examines US primary liver cancer incidence and incidence-based mortality trends over four decades. RESEARCH DESIGN AND METHODS: The SEER-9 registry was used to study primary liver cancer cases from 1978 to 2018. The incidence and mortality rates were calculated based on gender, age, race, and stage of diagnosis. Joinpoint regression software was used to calculate the annual percent change. RESULTS: The overall incidence rate of primary liver cancer from 1978 to 2018 increased by 2.71%/year (p<0.001). Rates in patients <50 years old began to fall in 2002 at a rate of -3.62%/year (p<0.001). Similarly, the incidence-based mortality rates for primary liver cancer increased by 2.15%/year (p<0.001). Whereas Whites incidence-based mortality rates began to plateau in 2012 (0.18%/year; p = 0.84), Blacks rates have declined since 2010 (-2.93%/year; p = 0.03), and Asian rates have declined since 1999 (-1.30%/year; p<0.001). CONCLUSION: While the overall primary liver cancer incidence and incidence-based mortality have been increasing over the last four decades, there was an observed decline in incidence and incidence-based mortality in recent years, especially among at-risk subgroups.

Improving care and survival of newborns with surgical conditions in Tanzania (TINY Tanzania): a focus on gastroschisis.

PURPOSE: Gastroschisis is associated with over 90% mortality in many sub-Saharan African countries. The introduction of the Gastroschisis Care Bundle at Muhimbili National Hospital (MNH) increased survival up to 60%. We aim to explain the impact of using implementation science methods to decentralize the care of babies with gastroschisis to other parts of Tanzania. METHODS: We used a Step-Wedge Implementation Science design to scale up gastroschisis care through training of providers, dissemination and current revision of evidence-based care protocols, advocacy, and engagement with stakeholders. We used mixed methods for data collection. Anonymous patient and provider evaluation data were collected using a nationwide Gastroschisis Database via REDCap. We evaluated the implementation and effectiveness of the care bundle in different hospitals in Tanzania. RESULTS: Decentralizing care nationally was feasible, acceptable, and adaptable. A total of nine trainings have been conducted training 420 providers (14 Master Trainers) reaching seven regions of Tanzania. The three advocacy national campaigns have ensured community reach and patient engagement. A countrywide gastroschisis database was developed to collect data on patients with gastroschisis, hosted locally at MNH with 332 patients' data entered in 1 year. The majority (90.2%) were treated using preformed silo bags with an overall survival of 28.5% in all centers. Late presentation and infection remain to be the main challenge. CONCLUSION: To achieve quality and sustainable surgical care, there is a need to design, implement, evaluate, and continuously improve context-relevant strategies to achieve and sustain the survival of neonates with congenital anomalies. Decentralization enables clear connectedness of hospitals, bringing care closer to patients.

Comparison of outcomes of radical and partial nephrectomy for sarcomatoid renal cell carcinoma: analysis of the national cancer database.

PURPOSE: To compare outcomes of radical (RN) and partial nephrectomy (PN) in Sarcomatoid Renal Cell Carcinoma (sRCC) utilizing a large national cohort. As RN is the reference standard for localized RCC with clinically aggressive features, PN in sRCC has been seldom studied. METHODS: We performed a retrospective cohort analysis of the National Cancer Database from 2004 to 2019 for patients who underwent PN and RN for sRCC (T1-T3N0-N1M0). We performed multivariable analyses (MVA) to determine factors associated with PN and all-cause mortality (ACM), and Kaplan-Meier Analysis (KMA) for overall survival (OS) in Charlson 0 patients who underwent PN vs. RN according to clinical stage. RESULTS: The cohort consisted of 5,265 patients [RN 4,582 (87.0%)/PN 683 (13.0%)]. Increased odds of receiving PN was associated with papillary RCC (OR = 1.69, p = 0.015); inversely with increasing age (OR = 0.99, p = 0.004), cT2-cT3 (OR = 0.23, p < 0.001), and cN1 (OR = 0.2, p < 0.001). Worsened ACM was associated with positive margins (HR = 1.59, p < 0.001), male (HR = 1.1, p = 0.044), Charlson [Formula: see text]2 (HR = 1.47, p < 0.001), cT2-cT3 (HR 1.17-1.39, p < 0.001-0.035), and cN1 (HR = 1.59, p < 0.001). Improved ACM was noted with PN (HR = 0.64, p < 0.001), increasing household income (HR = 0.77-0.79, p < 0.001), and private insurance (HR = 0.80, p = 0.018). KMA showed PN had improved 5-year OS compared to RN in cT1 (86.5% vs. 63.2%, p < 0.001), and cT3 (61.0% vs. 44.0% p < 0.001), but not cT2 (p = 0.67). CONCLUSION: In select patients, PN with negative margins may not compromise outcomes and may provide benefit when indicated. Patients with private insurance and highest income experienced improved survival suggesting disparity in care.

Metastatic disease and major adverse cardiovascular events preceding diagnosis are the main determinants of disease-specific survival of pheochromocytoma/paraganglioma: long-term follow-up of 303 patients.

Purpose: The natural history in unselected cohorts of patients with pheochromocytoma/ paraganglioma (PPGL) followed for a period >10 years remains limited. We aimed to describe baseline characteristics and outcome of a large cohort and to identify predictors of shorter survival. Methods: This retrospective single-center study included 303 patients with newly diagnosed PPGL from 1968 to December 31, 2023, in 199 prospectively supplemented since July 2020. Mean follow-up was 11.4 (range 0.3-50) years, germline genetic analyses were available in 92.1%. The main outcome measures were overall (OAS), disease-specific (DSS), recurrence-free (RFS) survival and predictors of shorter survival evaluated in patients with metastases at first diagnosis (n=12), metastatic (n=24) and nonmetastatic (n=33) recurrences and without evidence of PPGL after first surgery (n=234). Results: Age at study begin was 49.4 ± 16.3 years. There were 72 (23.8%) deaths, 15 (5.0%), 29 (9.6%) and 28 (9.2%) due to PPGL, cardiovascular disease (CVD) and malignant or other diseases, respectively. Median OAS, DSS1 (tumor-related) and DSS2 (DSS1 and death caused by CVD) were 4.8, 5.9 and 5.2 years (patients with metastases at first diagnosis), 21.2, 21.2 and 19.9 years, and 38.0, undefined and 38.0 years (patients with metastatic and with nonmetastatic recurrences, respectively). Major adverse cardiovascular events (MACE) preceded the first diagnosis in 15% (n=44). Shorter DSS2 correlated with older age (P ≤ 0.001), male sex (P ≤ 0.02), MACE (P ≤ 0.01) and primary metastases (P<0.0001, also for DSS1). Conclusion: The clinical course of unselected patients with PPGL is rather benign. Survival rates remain high for decades, unless there are MACE before diagnosis or metastatic disease.

Prognostic Nomograms for Patients With NF-Pan-NET After Pancreatectomy: A Retrospective Analysis Based on SEER Database.

AIMS: Surgical resection is the primary treatment option for patients diagnosed with nonfunctional pancreatic neuroendocrine tumors (NF-Pan-NETs). However, the postoperative prognostic evaluation for NF-Pan-NET patients remains obscure. This study aimed to construct an efficient model to predict the prognosis of NF-Pan-NET patients who have received surgical resection. METHODS: NF-Pan-NET patients after pancreatectomy were retrieved from the SEER database for the period of 2010 to 2019. A total of 2844 patients with NF-Pan-NET from SEER database were included in our study. After careful screening, six clinicopathological variables including age, grade, AJCC T stage, AJCC N stage, AJCC M stage, and chemotherapy were selected to develop nomograms to predict overall survival (OS) and cancer-specific survival (CSS) respectively of the patients. RESULTS: The novel models demonstrated high accuracy and discrimination in prognosticating resected NF-Pan-NET through various validation methods. Furthermore, the risk subgroups classified by the newly developed risk stratification systems based on the nomograms exhibited significant differences in both OS and CSS, surpassing the efficacy of the AJCC 8th TNM staging system. Novel nomograms and corresponding risk classification systems were developed to predict OS and CSS in patients with NF-Pan-NET after pancreatectomy. CONCLUSION: The models demonstrated superior performance compared to traditional staging systems, providing clinicians with more accurate and personalized guidance for postoperative surveillance and treatment.

Long-term survival after out-of-hospital cardiac arrest in children: outcomes in Andalusia in 2008-2019. / Supervivencia a largo plazo de la parada cardiaca extrahospitalaria en edad pediátrica: resultados en Andalucía durante el periodo 2008-2019.

OBJECTIVE: To determine survival to discharge and neurological outcomes on long-term follow-up of pediatric patients attended for out of-hospital cardiac arrest (OHCA). METHODS: Retrospective study based on an ongoing OHCA registry. Patients aged 16 years or younger were included. Futile resuscitation attempts were excluded. Neurological outcome on hospital discharge and on follow-up was based on variables in the Pediatric Cerebral Performance Category (PCPC) scale. Cases from January 1, 2008, through December 31, 2019, were extracted, and 2 surveys were carried out in May 2021 and January 2023. Patient follow-up time ranged from 1 to 13 years. RESULTS: Of the 13 778 patients in the registry, we found 277 (2.0%) who were aged 16 years or younger. One hundred thirty-seven patients (49.5%) were transported to a hospital, and spontaneous circulation was restored in 99 (35.7%). Thirty-six patients (13%) were discharged. The median (interquartile range) follow-up time was 2172 (978-3035) days. Thirty-one of these patients (86.1%) were alive at follow-up, 3 had died, and 2 were lost to follow-up. Neurological outcomes had worsened in 2 and improved in 6 patients. The neurological outcome of 27 of the 31 patients with complete follow-up data (87.1%) was good (PCPC scores of 1 or 2). CONCLUSIONS: In spite of the low incidence of shockable rhythm in pediatric OHCA, survival with a good neurological outcome is comparable to survival in adults. Children who are discharged after OHCA maintained or improved their neurological function over the long term.

OBJETIVO: Conocer la supervivencia al alta y la evolución neurológica tras seguimiento a largo plazo de pacientes pediátricos atendidos por parada cardíaca extrahospitalaria. METODO: Estudio retrospectivo basado en un registro continuo de parada cardiaca extrahospitalaria. Se incluyeron los pacientes pediátricos (edad menor o igual a 16 años). Se excluyeron reanimaciones consideradas fútiles. Se tomaron como variables resultado el estado neurológico al alta hospitalaria y al seguimiento de los pacientes, siguiendo el modelo de la Pediatric Cerebral Performance Category. El periodo fue del 1 de enero de 2008 al 31 de diciembre de 2019. Se realizaron dos encuestas, en mayo del 2021 y enero del 2023 con un periodo de seguimiento entre 1 y 13 años. RESULTADOS: De los 13.778 pacientes, 277 (2,0%) eran menores de 16 años; 137 (49,5%) trasladados al hospital, 99 de ellos (35,7%) con recuperación de circulación espontánea. Recibieron el alta hospitalaria 36 pacientes (13%). En el seguimiento, mediana (RIC) de 2.172 [978-3.035] días, 31 pacientes (86,1%) seguían con vida, 3 pacientes fallecieron y en dos casos no obtuvimos información. Dos pacientes sufrieron un empeoramiento del estado neurológico y 6 mejoraron. Finalmente, 27 de los 31 pacientes (87,1%) que completaron el seguimiento tenían una buena situación neurológica (PCPC1-2). CONCLUSIONES: A pesar de presentar una incidencia baja, la supervivencia con buen estado neurológico al alta hospitalaria de la parada cardiorrespiratoria extrahospitalaria pediátrica es comparable a la del adulto. Los pacientes pediátricos que recibieron el alta hospitalaria tras una parada cardiorrespiratoria extrahospitalaria mantuvieron o mejoraron su estado neurológico en el seguimiento a largo plazo.

Effect of CMV Mismatch on Heart Transplant Outcomes Using a Surveillance and Preemptive Strategy.

PURPOSE: The aim of the study was to determine outcomes after heart transplantation for cytomegalovirus (CMV) mismatched patients (D+/R-) who underwent a surveillance and preemptive therapy protocol, compared to nonmismatch patients. METHODS: A review of patient records from January 2010 to December 2020 with follow-up to October 2023 was done. The protocol consisted weekly surveillance with CMV PCR starting 4 weeks after transplant continuing up until the patient seroconverts or up to 3 months posttransplant if the patient does not seroconvert. Valganciclovir was given for 2 weeks to those who seroconverted. RESULTS: Two hundred and twenty-one patients were included, and 23% were mismatched patients. Overall survival was not different between CMV groups (p = NS). Causes of death and morbidities were also not significantly different (p = NS). Sixty-six percent of mismatch patients seroconverted, and there was also a significantly older donor age in the seroconverted patients compared to nonseroconverted patients (41 ± 11 vs. 29 ± 12 years, p < 0.005), indicating a higher risk donor profile. A multivariate Cox regression including donor age showed that there was no increase in mortality in the seroconverted mismatches compared to nonmismatch patients (p = NS). CONCLUSIONS: There is no significant increased mortality or morbidity using a CMV surveillance and preemptive therapy protocol. The effect of donor age on seroconversion of mismatches requires further validation.

Predictors of Care Home Admission and Survival Rate in Patients With Syndromes Associated With Frontotemporal Lobar Degeneration in Europe.

BACKGROUND AND OBJECTIVES: Data on care home admission and survival rates of patients with syndromes associated with frontotemporal lobar degeneration (FTLD) are limited. However, their estimation is essential to plan trials and assess the efficacy of intervention. Population-based registers provide unique samples for this estimate. The aim of this study was to assess care home admission rate, survival rate, and their predictors in incident patients with FTLD-associated syndromes from the European FRONTIERS register-based study. METHODS: We conducted a prospective longitudinal multinational observational registry study, considering incident patients with FTLD-associated syndromes diagnosed between June 1, 2018, and May 31, 2019, and followed for up to 5 years till May 31, 2023. We enrolled patients fulfilling diagnosis of the behavioral variant frontotemporal dementia (bvFTD), primary progressive aphasia (PPA), progressive supranuclear palsy (PSP) or corticobasal syndrome (CBS), and FTD with motor neuron disease (FTD-MND). Kaplan-Meier analysis and Cox multivariable regression models were used to assess care home admission and survival rates. The survival probability score (SPS) was computed based on independent predictors of survivorship. RESULTS: A total of 266 incident patients with FTLD were included (mean age ± SD = 66.7 ± 9.0; female = 41.4%). The median care home admission rate was 97 months (95% CIs 86-98) from disease onset and 57 months (95% CIs 56-58) from diagnosis. The median survival was 90 months (95% CIs 77-97) from disease onset and 49 months (95% CIs 44-58) from diagnosis. Survival from diagnosis was shorter in FTD-MND (hazard ratio [HR] 4.59, 95% CIs 2.49-8.76, p < 0.001) and PSP/CBS (HR 1.56, 95% CIs 1.01-2.42, p = 0.044) compared with bvFTD; no differences between PPA and bvFTD were found. The SPS proved high accuracy in predicting 1-year survival probability (area under the receiver operating characteristic curve = 0.789, 95% CIs 0.69-0.87), when defined by age, European area of residency, extrapyramidal symptoms, and MND at diagnosis. DISCUSSION: In FTLD-associated syndromes, survival rates differ according to clinical features and geography. The SPS was able to predict prognosis at individual patient level with an accuracy of ∼80% and may help to improve patient stratification in clinical trials. Future confirmatory studies considering different populations are needed.

Effectiveness of treatment of oropharyngeal carcinoma patients.

OBJECTIVE: Aim: To analyze the results of treatment of patients with oropharyngeal carcinoma. PATIENTS AND METHODS: Materials and Methods: 276 patients with oropharyngeal carcinoma were treated in 2008-2021. Neoadjuvant chemotherapy consisted of three to six cycles: paclitaxel 175 mg/m2 and carboplatin 350 mg/m2 (or cisplatin 100 mg/m2) on the first day. The interval between cycles was 21 days. After the cycles, all patients were prescribed a course of radiation therapy in a total focal dose (TFD) of 65 Gy. The outcome of treatment was assessed by the degree of tumor regression according to RECIST criteria one month after the end of combination treatment. Statistical processing was performed using STATISTICA 6.1 software (StatSoftInc). RESULTS: Results: The three- and five-year survival rates of the examined patients with oropharyngeal carcinoma after treatment were 40.8% respectively (95% CI 33.7 - 47.9) and 27.0%, (95% CI 20.6 - 33, 4) with a median survival of 36 months with 95% CI (35.5 - 40.2). Processing was performed using STATISTICA 6.1 software (StatSoftInc). CONCLUSION: Сonclusions: Analysis of treatment of patients with oropharyngeal carcinoma with predominance of squamous cell carcinoma (90.6%), localized primarily in the palatine tonsil (73.2%), with the most common stages T3N1M0 (30.1%) and T3N1M0 %), with regional metastases to the lymph nodes of the neck (89.9%), showed that the effectiveness of treatment of patients is quite high, because in most of the examined in the short term after combined treatment there was complete or partial regression of the tumor (91.7%), no progression of the oncological process was detected in any of them.
