Optimising outcomes for frail patients with oesophagogastric (OG) cancers: The impact of dose reduction and comprehensive geriatric assessment.

303 Background: Delivery of appropriate management of elderly patients with OG malignancies in the palliative setting remains challenging and unpredictable. Incidence of OG cancers increases markedly with age, and there are growing numbers of elderly, frail and medically complex patients referred to oncology services for treatment. An adaptive approach to their management is required, tailored to their complex medical needs. The GO2 study sought to optimise chemotherapy delivery in this cohort and demonstrated that upfront dose reductions do not reduce progression-free survival in OG cancers. We analysed the treatment and outcome of elderly patients undergoing first-line palliative chemotherapy at our centre, with or without comprehensive geriatric assessment (CGA). Methods: We retrospectively analysed the records of patients over the age of 75 treated at our centre between May 2011 and March 2023. Progression-free survival (PFS) was calculated from the date of treatment initiation to date of radiological progression, or 19 th March 2024 if patients had not progressed. Overall survival (OS) was calculated from treatment initiation to date of death per the electronic health record, or 19 th March 2024 if patients had not died. Grade 3 (G3) toxicities and dose reductions (DRs) were identified from medical records. Statistical analyses were performed using R v4.3.3. Results: 82 patients were included in the analysis. Overall median PFS was 6.5 months (1-107 months) and median OS was 10 months (1-107 months). Patients who qualified for chemotherapy with immunotherapy had improved PFS (median 16 months, range 2-27 months) and OS (median 16 months, range 10-27 months). G3 toxicities were increased in patients without upfront DR (44% vs. 30%). The most significant predictor for survival in multivariate analysis was performance status (PS), which was associated with worse PFS (hazard ratio 2.66, range 1.35–5.35, p = 0.004), and OS (hazard ratio 6.13, range 2.79–13.44, p < 0.001). Age was not associated with survival. Consistent with the GO2 trial, there was no association between upfront DR and PFS (p = 0.13) or OS (p = 0.72). 38% of patients underwent CGA as part of their workup for chemotherapy. These patients were more likely to have upfront DR (61% vs. 47%). In this cohort, G3 toxicity rates were comparable in patients with PS 0-1 who underwent CGA (39% vs. 35%). In patients with PS ≥ 2, G3 toxicity rates were higher in those who did not undergo CGA (67% vs. 30%). Conclusions: Upfront DR in elderly patients is safe and does not impact survival but does reduce the burden of toxicity. PS, rather than age, is a better predictor of survival and treatment outcome. CGA may help mitigate toxicity burden in patients with poor performance status.

Improving Hospital Palliative Care Between COVID-19 Waves: A Retrospective Cohort Study

ContextA specialist palliative care service in an acute hospital characterized care patterns during the first wave of the COVID-19 pandemic. There were delayed referrals for minoritized ethnic groups. COVID-19 treatments (dexamethasone, anticoagulation, remdesivir) alongside service changes were introduced in the second wave. ObjectiveTo examine changes in care patterns and trends in the context of COVID-19 treatments. A secondary objective is to examine differences in ethnic disparity between the first and second wave of COVID-19. MethodsRetrospective cohort study comparing patients referred to an acute hospital palliative care service with confirmed COVID-19 infection either at the peak of the first (Mar-Apr 2020, W1), or second (Dec 2020-Feb 2021, W2) wave of the pandemic. Demographic, clinical characteristics, and outcomes data were compared using statistical tests; generalized linear mixed models for modelling of elapsed time from admission to referral; and survival analysis. ResultsData from 165 patients (W1 = 60, W2 = 105) were included. Patients in W1 were referred earlier to palliative care than in W2, particularly in the first 10 days from admission. Receiving dexamethasone or anticoagulants, and absence of dementia, hypertension, and fever were associated with longer time to referral to palliative care. Delays in referrals of Black and Asian patients during W1 was no longer observable in W2. There was no association between socioeconomic status and care patterns and trends. The Australian-modified Karnofsky Performance Status (HR < 0.92, 95% CI: 0.88–0.95) and phase of illness (HR > 3, 95% CI: 2–5) were good predictors of survival. ConclusionOur findings have the potential to inform strategies that improve palliative care response and equity beyond COVID-19, and in future pandemics or crises.

394. ESOPHAGEAL STENTING IN ESOPHAGEAL CANCER PATIENTS WITH PERFORATION AND FISTULA

Abstract Background Esophageal perforation and fistula to the respiratory system are serious problems in esophageal cancer patients. Esophageal self-expandable metal stent (SEMS) placement has become a popular treatment for this problem. This retrospective study aimed to evaluate the factors associated with clinical outcomes following the placement of a SEMS in esophageal cancer patients with perforation and fistula. Methods Data from 43 esophageal cancer patients with perforation and fistula who underwent esophageal SEMS placement at Prince of Songkla University Hospital between January 2008 and June 2023 were reviewed. Statistical analyses, including chi-square tests and Kaplan-Meier methods, were employed for comparisons and survival calculations. Results The SEMS location was the middle esophagus in 76.8% and 11.6% in each of the lower and upper esophagus. The disease was stage IV in 62.8% and stage III in 37.2%. 46.5% had a history of chemoradiotherapy. The perforation and fistula penetrated into the left bronchus in 39.5%, right bronchus 18.6%, trachea 16.3%, lung 14% and mediastinum 11.6%. The SEMS technique was successful in all patients. The median stent patency was 38.5 days. Tumor overgrowth was the major cause of stent obstruction. The median overall survival was 40 days. Initial success of the SEMS placement was the only predictor of better survival. Conclusion Esophageal SEMS placement in esophageal cancer perforation and fistula cases is technically uncomplicated. Although these advanced esophageal cancer patients had a poor prognosis, the esophageal SEMS provided symptom relief and improved quality of life for their remaining time.

Challenges around diagnosis of early onset colorectal cancer, and the case for screening.

Colorectal cancer (CRC) is the third most diagnosed cancer in the world, with an estimated 1.93 million cases diagnosed in 2020. While the overall CRC incidence in many countries is falling there has been a dramatic increase in CRC in those aged under 50 (early onset colorectal cancer, EOCRC). The reason for this increase in EOCRC is unknown. As the best predictor of survival is stage at diagnosis, early diagnosis is likely to be beneficial and population screening may facilitate this. A narrative review of the literature was undertaken. Improving time to diagnosis in symptomatic patients is beneficial. However, by the time symptoms develop, over a third of patients already have metastatic disease. Screening asymptomatic patients (with Faecal Immunochemical test (FIT) and colonoscopy) has been proved to be effective in older patients (>60 years). In younger populations, the decreasing incidence rates of CRC previously made cost effectiveness, compliance and therefore benefit questionable. Now, with the increasing incidence of CRC in those under 50 years of age, modelling suggests screening with FIT and colonoscopy is cost effective from 40 years of age. There is evidence that some countries screening below 50 have prevented the rise in EOCRC incidence. Additionally the use of new and novel non-invasive biomarkers may also be able to improve the accuracy of screening asymptomatic patients. Diagnosis of EOCRC once symptoms develop is often too late, and screening patients from age 40 is the best way to improve outcomes in this group.

Evaluation of different scoring systems for repeating Transarterial Chemoembolization in Egyptian patients with Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) patients undergoing transarterial chemoembolization (TACE) have a diverse range of outcomes due to their high degree of heterogeneity. Therefore, different predictive scoring systems have been created to assist in decision-making regarding retreatment with TACE. We compared the predictive capabilities of different scoring systems, such as ART, ABCR, and SNACOR, for prediction of the outcome of subsequent TACE in HCC patients. In this retrospective study, the three scoring systems were compared for their capability of predicting the outcome of repeating TACE in 149 HCC patients treated at the National Liver Institute, Egypt, between January 2017 and December 2019. We used the likelihood ratio to select the model with the highest predictive capability for overall survival (OS). According to our data, the amount of tumor, the change in Barcelona Clinic Liver Cancer (BCLC) stage following TACE, and the SNACOR score (with a 95% confidence range for HR 1.0305-1.256 and p-value = 0.0106) were the most predictive variables. It was also shown that the ABCR score was a good predictor of survival (90 patients had an ABCR score ≤ 0 with a P- value <0.0001, 56 patients had 0 < ABCR < 4 with a P-value <0.0001, and the ART score was not useful in predicting OS (P-value = 0.18). The SNACOR score is the most predictive score for OS and would be the most helpful scoring system in decision-making regarding retreatment with TACE.

Long-term outcomes after resection of extra-ampullary duodenal adenocarcinomas: single-center experience

BackgroundExtra-ampullary duodenal adenocarcinoma is a rare neoplasm. The data on long-term outcomes after curative resection are limited, and the role of systemic chemotherapy is not defined in these tumors. This study aimed to investigate the prognostic factors and survival of patients with resected primary duodenal cancers. MethodsA retrospective analysis of patients with resected primary duodenal adenocarcinoma was conducted between January 2010 and December 2023. ResultsA total of 59 patients were included in the study. The median age of patients was 60 years (IQR, 33–79), and 79.7% of patients were males. The second part of the duodenum was the most common location of the tumor in 42 patients (71.2%). Pancreaticoduodenectomy was performed in 57 patients (96.6%), and segmental duodenal resection was performed on 2 patients (3.4%). The median lymph node harvest was 18 (IQR, 2–70). Adjuvant chemotherapy was administered to 39 patients (66.1%). At a median follow-up of 32.00 months (IQR, 3.29–166.74), the 5-year overall survival (OS) and disease-free survival rates were 55.0% and 49.3%, respectively. Regarding prognostic factors, lymph node ratio (LNR; hazard ratio [HR], 2.94; 95% CI, 1.01–8.53), adenocarcinoma subtype (intestinal vs nonintestinal; HR, 4.59; 95% CI, 1.59–13.23), and margin of resection (HR, 44.24; 95% CI, 4.02–486.19) were significant factors for OS. ConclusionMargin-free surgical resection offers the best chance of cure for operable duodenal adenocarcinoma. The intestinal subtype and low LNR are predictors of better survival, and the role of adjuvant chemotherapy remains debatable until prospective randomized trials are conducted.

Prognostic factors and outcome of relapsed/progressive pediatric Ewing sarcoma: single-center 10-year experience

BackgroundEwing sarcoma (ES) is the second most common primary malignant bone tumor in children and adolescents. Despite more intensive chemotherapy regimens and improved local control therapy, there is still a considerable rate of recurrent/progressive disease.MethodsA retrospective study of 50 relapsed/progressive ES patients who were treated at the National Cancer Institute (NCI), Cairo University, during the period from 1st of January 2008 to the end of December 2018, to assess different prognostic variables and disease outcomes.ResultsOut of fifty eligible cases, 32 patients (64%) had disease recurrence, and 18 (36%) developed disease progression on treatment. The median follow-up period was 7.4 months. The median overall survival (OS) was 7.5 months, and the cumulative OS was 64% at 6 months and 32.6% at 1 year. The cumulative event-free survival (EFS) was 41.3% at 6 months and 22.3% at 1 year. Patients with disease recurrence had better OS and EFS than patients with disease progression (p = 0.019). Patients who underwent local control at relapse/progression had a significantly better outcome than patients who received chemotherapy only (p < 0.001). Recurrence > 2 years from initial diagnosis was the only independent predictor of better survival outcome.ConclusionsPatients with relapsing/progressive ES portended a poor outcome, with disease progression on treatment faring worse than relapse. Better outcome was observed in patients who experienced recurrence > 2 years after diagnosis, patients with disease recurrence rather than disease progression on treatment, and patients who underwent local control along with intensive chemotherapy.

The Revised Trauma Score: A Better Early Predictor for Survival of Head Trauma Patients than the Glasgow Coma Scale-Age-Pressure Score

Purpose: Trauma is a common cause of death worldwide and head injury is the most common form of trauma presented at the Emergency Department. Physiological scores are better for predicting outcome than anatomical scores. To reduce mortality rates, this study compared the capacity of the revised trauma scores (RTS) and the Glasgow coma scale- age- pressure (GAP) scores to predict the survival of patients and effectively channel resources.Methods: An observational study of head trauma patients aged 12 to 80 years was performed at a tertiary care center (N = 500). We noted demographic information, RTS and GAP trauma scores, and outcomes in terms of mortality or survival at 24 hours, 48 hours, and 7 days.Results: Of the 500 patients who were enrolled, 414 (82.8%) survived 24 hours, 373 (74.6%) survived 48 hours, and 265 (53%) survived after 7 days. Using the Receiver Operating Characteristic curve, the RTS score was a significantly better predictor of survival in patients with head trauma than the GAP score at 24 hours (p = 0.044) and 48 hours (p = 0.049) of admission. The results were not significantly different at 7 days (p = 0.240). Mortality or survival outcomes were not significantly different between the RTS and GAP scores (p = 0.373).Conclusion: RTS appears to be a better early predictor for mortality (within 48 hours of admission) than the GAP score. The RTS was more effective in directing the triage of patients which improved survival rates in head trauma patients.

Stratification of Homologous Recombination Deficiency-Negative High-Grade Ovarian Cancer by the Type of Peritoneal Spread into Two Groups with Distinct Survival Outcomes.

Homologous recombination deficiency (HRD) has evolved into a major diagnostic marker in high-grade ovarian cancer (HGOC), predicting the response to poly (adenosine diphosphate-ribose) polymerase inhibitors (PARPi) and also platinum-based therapy. In addition to HRD, the type of peritoneal tumor spread influences the treatment response and patient survival; miliary type tumor spread has a poorer predicted outcome than non-miliary type tumor spread. Known methods for HRD assessment were adapted for our technical requirements and the predictive-value integrated genomic instability score (PIGIS) for HRD assessment evolved as an outcome. PIGIS was validated in HGOC samples from 122 patients. We used PIGIS to analyze whether the type of tumor spread correlated with HRD status and whether this had an impact on survival. We demonstrated that PIGIS can discriminate HRD-positive from HRD-negative samples. Tumors with a miliary tumor spread are HRD-negative and have a very bad prognosis with a progression-free survival (PFS) of 15.6 months and an overall survival (OS) of 3.9 years. However, HRD-negative non-miliary spreading tumors in our cohort had a much better prognosis (PFS 35.4 months, OS 8.9 years); similar to HRD-positive tumors (PFS 34.7 months, OS 8.9 years). Our results indicate that in a predominantly PARPi naïve cohort, the type of tumor spread and concomitant cytoreduction efficiency is a better predictor of survival than HRD and that HRD may be an accidental surrogate marker for tumor spread and concomitant cytoreduction efficiency. It remains to be determined whether this also applies for sensitivity to PARPi.

Remote monitoring is an independent predictor of better survival in patients with ischemic cardiomyopathy and implantable cardioverter-defibrillators

Abstract Introduction Despite improvements in pharmacotherapy and advancements in invasive techniques, patients with ischemic cardiomyopathy are at high risk of adverse events and death. Strategies aimed at improving prognosis, including patient-centered individualization of care are needed. Remote monitoring (RM) of patients with heart failure, which allows for a continuous assessment of device- and some patient-related parameters, has been shown to reduce the risk of hospitalization and death, although no analyses were focused specifically on patients with ischemic cardiomyopathy after percutaneous coronary intervention (PCI). Purpose To determine whether RM is associated with outcomes in patients with ischemic cardiomyopathy after percutaneous coronary intervention. Methods The clinical, echocardiographic and angiographic data of consecutive patients with ICM and ICD or CRT-D, who had undergone PCI were obtained from the single-centre COMMIT-HF registry. Each consecutive patient with ICM was offered RM at the discretion of the treating physician. The RM center in our facility monitors patients with cardiac implantable devices in all working days. In case of any clinical, or device-related events potentially requiring reaction, patients are telephonically invited to contact healthcare system, either in the local emergency departments, or in our hospital, or outpatient clinic. Patients supervised with RM undergo routine in-person visits in the outpatient device clinic every 12 months. In the conventional arm, routine visits in the outpatient clinic occur every 6 months. The long-term data were acquired from the National Health Fund – the sole Polish healthcare provider. The primary outcome of the study was 36-month all-cause mortality. Results In the years 2009-2017, there were a total of 1019 patients with ICM and ICD, who underwent PCI, and those constituted the study group. Of those, 227 (22.3%) were monitored remotely, while the remaining were treated conventionally. The studied groups did not differ significantly, apart from that the patients with RM had a history of CABG, and had a lower mean left ventricular ejection fraction (LVEF, 26% vs 32%, p&amp;lt;0.001) than subjects without RM, while the percentage of CRT-D devices was significantly higher in patients with RM (36.2% vs 6.2%, p&amp;lt;0.001). The 36-month all-cause mortality rate was 18.9% in patients monitored remotely and 25.3% in subjects without RM (p log rank = 0.028). In the multivariable analysis, RM was identified as an independent predictor of lower mortality. The other variables independently associated with higher survival were lower age, absence of anemia, optimal glomerular filtration rate, and higher LVEF. Conclusions Remote monitoring of patients with ischemic cardiomyopathy is independently associated with lower all-cause mortality in a real-world cohort of patients with ICDs.Baseline characteristicsMultivariable analysis

Improved overall survival in patients developing endocrine toxicity during treatment with nivolumab for advanced non-small cell lung cancer in a prospective study

PurposeImmune checkpoint inhibitors (ICPIs) disrupting PD-1/PD-L1 axis have revolutionized the management of advanced non-small cell lung cancer (NSCLC). Some studies identified the development of endocrine toxicity as predictor of better survival in cancer patients treated with ICPIs. The aim of study was to evaluate survival and new onset of immune-related endocrine adverse events (irAEs) in patients treated with nivolumab for advanced NSCLC.MethodsIn a prospective study, 73 patients with previously treated advanced NSCLC received nivolumab in monotherapy. Blood samples were collected at each cycle to monitor thyroid autoimmunity, thyroid, adrenal and somatotroph axes, while thyroid morphology was evaluated by ultrasonography.ResultsAn impaired thyroid function was recorded in 23.4% of patients (n = 15). Eight patients developed asymptomatic transient thyrotoxicosis (ATT) evolving to hypothyroidism in 50% of cases. In addition, seven patients developed overt hypothyroidism without ATT and with negative autoantibodies. Patients who developed hypothyroidism proved to have better overall survival (OS) as compared with non-developers at both univariate (p = 0.021) and multivariate analyses (p = 0.023). The survival curve of patients with reduced IGF-I at baseline, or displaying its reduction during the follow-up, showed significantly reduced median survival compared to patients with normal/high IGF-I levels (p = 0.031).ConclusionsThyroid function abnormalities are the major irAEs in patients treated with nivolumab, and hypothyroidism onset is associated with prolonged survival. Our findings indicate that the development of hypothyroidism is a positive predictive biomarker of nivolumab antitumor efficacy in patients with NSCLC. Low IGF-I levels could represent a negative prognostic factor during nivolumab therapy.

Utility of Initial Tumor Reduction as a Prognostic Factor in Esophageal Squamous Cell Cancer Patients Undergoing Neoadjuvant Chemotherapy Followed by Surgery : A Retrospective Cohort Study.

While a neoadjuvant chemotherapy regimen using docetaxel, cisplatin, and 5-fluorouracil (NAC-DCF) is considered the standard treatment for locally advanced esophageal cancer (EC) in Japan, a reliable marker for early prediction of treatment efficacy remains unclear. We investigated the utility of the tumor response after a first course of NAC-DCF as a post-surgery survival predictor in patients with EC. We enrolled 150 consecutive patients who underwent NAC-DCF followed by surgery for EC between September 2009 and January 2019. The initial tumor reduction (ITR), defined as the percentage decrease in the shorter diameter of the tumor after the first course of NAC-DCF, was evaluated using computed tomography. We analyzed the relationship between ITR, clinicopathological parameters, and survival. The median ITR was 21.07% (range -11.45 to 50.13%). The optimal cut-off value for ITR for predicting prognosis was 10% (hazard ratio [HR] 3.30, 95% confidence interval [CI] 1.98-5.51), based on univariate logistic regression analyses for recurrence-free survival (RFS). Compared with patients with ITR <10%, patients with ITR ≥10% showed a significantly higher proportion of ypM0 (80.0% vs. 92.5%) and responders in terms of overall clinical response (50.0% vs. 80.8%). Multivariate analysis for RFS revealed that ypN2-3 (HR 2.78, 95% CI 1.67-4.62), non-response in terms of overall clinical response (HR 1.87, 95% CI 1.10-3.18), and ITR <10% (HR 2.48, 95% CI 1.42-4.32) were independent prognostic factors. Tumor response after the first course of NAC-DCF may be a good predictor of survival in patients with EC who underwent NAC-DCF plus surgery.

High-tissue FRMD6 expression predicts better outcomes among colorectal cancer patients

Introduction Colorectal cancer (CRC) is the second most common cause of cancer-related deaths. The hippo pathway works as a regulator of organ growth and is often a target for mutations in cancer. Ferm domain containing protein 6 (FRMD6) is an activator of the hippo pathway. This study aimed to explore the role of FRMD6 in CRC and to determine how well it works as a prognostic factor among CRC patients. Methods The tumor expression of FRMD6 was evaluated using immunohistochemistry in 538 colorectal patients operated on at Helsinki University Hospital. We assessed FRMD6 expression with clinicopathological parameters and the impact of FRMD6 expression on survival. Results Patients with a high FRMD6 expression exhibited a better prognosis (univariable hazard ratio [HR] 0.58, 95% confidence interval [CI] 0.41–0.81), with a 5-year disease-specific survival (DSS) of 66.3%. By contrast, patients with a low FRMD6 expression had a 5-year DSS of 52.8%. A high FRMD6 expression level served as an independent predictor for better survival in the Cox multivariable survival analysis (HR 0.53, 95% CI 0.33–0.86). Discussion To our knowledge, this is the first study to show that a high FRMD6 expression is an independent marker for a better prognosis in CRC and could help determine the prognosis for CRC patients.

Long-term follow-up in high-grade meningioma and outcome analysis.

The determinants of progression-free survival (PFS) and overall survival (OS) for higher-grade meningiomas have not been clearly established and to summarize the long-term clinical outcome for patients with grade 2 or 3 meningioma and assess the PFS and OS factors. The study included all individuals, who had undergone surgical removal of cerebral meningiomas between 2005 and 2020 and whose histological results suggested a World Health Organization (WHO) grade 2 or grade 3 diseases. Kaplan-Meier curves are plotted to examine tumor control and OS after the follow-up. The reverse Wald logistic regression and Mantel-Cox test were used in multivariate analysis for tumor recurrence and mortality. There were 94 individuals enrolled with 82 having WHO grade 2 tumors and 12 having WHO grade 3 lesions. Gross total resection of the tumor was present in 73 patients (78%), and adjuvant radiotherapy (RT) was administered to 43 (45.7%) individuals. During the course of the study, 17 patients died. The WHO grade of the tumor, the extent of resection, and the absence of bone involvement were all independent predictors of better survival in a multivariate analysis. Furthermore, whereas adjuvant RT after surgery enhanced survival, it was not statistically significant (hazard ratios [95% confidence interval CI] = 1.91 [0.15-23.52] [P = 0.61]). The degree of tumor excision is the strongest predictor of PFS and OS. In the event of a recurrence, rather than opting for upfront radiation, a second surgery with the goal of maximum safe resection should be performed.

Water temperature at the time of the catch-and-release event is a better predictor of survival in Atlantic salmon (Salmo salar) than acute water temperature changes before and after.

Despite studies on the effect of catch-and-release on the survival of Atlantic salmon (Salmo salar) being widespread in the literature, studies to date have failed to evaluate the potential role of thermal history. Herein, we show that despite cooler conditions post-release, 4/18 (22%) salmon died when caught-and-released at water temperatures ≥20°C, whereas 1/13 (8%) salmon caught-and-released at water temperatures ≤20°C, but who encountered mean water temperatures ≥20°C post-release, died. We conclude water temperature at time of the catch-and-release event remains the most suitable predictor of post-release survival.

Survival Predictors Before Preoperative Adjuvant Chemotherapy in Patients With Locally Advanced Esophageal Squamous Cell Carcinoma.

Radical resection after preoperative adjuvant chemotherapy (NAC) is a standard treatment for patients with locally advanced esophageal squamous cell carcinoma (LAESCC), but its outcome remains unsatisfactory. In order to develop a personalized treatment program for LAES, we herein compared the survival prediction utility of five pre-NAC nutritional, inflammatory, and immune indexes in patients with LAESCC. We evaluated the survival of 203 patients with LAESCC who underwent radical resection after NAC from January 2011 to September 2019 for the following representative pre-NAC nutritional, inflammatory, and immune indices: modified Glasgow Prognostic Score, Prognostic Nutritional Index, C-reactive protein/albumin ratio, serum neutrophil/lymphocyte ratio, and Geriatric Nutrition Risk Index (GNRI) were evaluated for their impact on survival. Of the five indices, GNRI was the best predictor of survival as determined by the area under the curve (p<0.05). When patients were divided into three groups according to the nutritional risk assessment of Bouillanne et al. using the pre-NAC GNRI, the 5-year overall survival (OS) and recurrence-free survival (RFS) were significantly stratified (p<0.001). On multivariate analysis, the GNRI independently identified a poor OS group [group 1: hazard ratio (HR)=2.598, p=0.002; group 2: HR=6.257, p<0.001] and a high recurrence risk group (group 1: HR=1.967, p=0.016; group 2: HR=4.467, p<0.001). In patients with LAESCC, GNRI may be the most accurate, reliable, and useful prognostic factor among the five major systemic inflammatory and nutritional indices.

Lower product of magnesium × potassium is associated with higher mortality in chronic hemodialysis patients: a cohort study

This study aimed to investigate the Mg × K product on the mortality risk of hemodialysis patients with concomitant hypokalemia and lower magnesium levels. This was a prospective observational study of patients in a HD center in southern Taiwan. A total of 444 HD patients were divided into 5 groups by the Mg × K product: group 1, bottom quintile, median Mg × K: 7.87, IQR: 7.03–8.12 (n = 89, age: 64 ± 13 years old); group 2, median Mg × K: 9.37, IQR: 8.97–9.86 (n = 89, age:62 ± 13 years old); group 3, median Mg × K: 10.95, IQR: 10.50–11.26 (n = 89, age:64 ± 13 years old); group 4, median Mg × K: 12.30, IQR: 11.87–12.82 (n = 89, 61 ± 12 years old); and group 5, top quintile, median Mg × K: 14.92, IQR:14.07–16.23 (n = 88, 62 ± 11 years old). The patients were followed up for 2 years to determine the risk of all-cause mortality. Patients with a lower Mg × K product had more comorbidities, malnutrition-inflammation status, and a higher mortality risk. Using multivariable Cox regression analysis, a higher Mg × K [HR, 0.89; 95%CI (0.81–0.98)] was found to be an independent predictor of better survival. HD patients with a lower Mg × K product had more comorbidities, a marked malnutrition-inflammation status, and were associated with long-term mortality. A higher Mg × K value is a favorable survival factor.

Penile Cancers Attributed to Human Papillomavirus Are Associated with Improved Survival for Node-positive Patients. Findings from a Norwegian Cohort Study Spanning 50 Years

BackgroundHuman papillomavirus (HPV) infection is a risk factor for the development of penile squamous cell carcinoma (PSCC). It remains inconclusive whether HPV-related PSCC has a different prognosis from non–HPV-related PSCC. ObjectiveTo investigate the relationship between HPV status and survival as well as temporal changes in the proportion of HPV-related PSCC. Design, setting, and participantsA retrospective cohort of 277 patients treated in Norway between 1973 and 2022 was investigated for HPV DNA in tumor tissue. Clinicopathological variables and disease course were registered. Outcome measurements and statistical analysisKaplan-Meier curves and Cox regression were used to investigate the determinants of cancer-specific survival (CSS). The chi-square test for trend in proportions enabled investigation of temporal changes in the HPV-related proportion of PSCC patients treated in Western Norway (n = 211). Results and limitationsHPV DNA was detected in tumor tissue from 131 (47%) patients. Stratified by HPV status, 5-yr CSS did not differ between groups (p = 0.37). When investigating only node-positive patients, however, presence of HPV DNA was an independent predictor of better survival in multivariable Cox regression after adjustment for age, nodal stage, and adjuvant therapy (hazard ratio 0.54, 95% confidence interval: [0.30–0.99], p = 0.04). In cases from Western Norway, an increasing proportion of HPV-related cases over time was found (p = 0.01). The main limitation is the retrospective study design. ConclusionsHPV DNA in tumor tissue was associated with significantly better CSS for node-positive patients. The proportion of HPV DNA–positive PSCC has increased significantly in Western Norway over the past 50 yr. Patient summaryWe investigated the impact of human papillomavirus (HPV) on the survival of penile cancer patients treated over a 50-yr period in Norway. We found that for patients with lymph node metastasis, survival was better for HPV-related cases. We also found that the proportion of cases due to HPV has increased in Western Norway.

Prognostic association supports indexing size measures in echocardiography by body surface area

Body surface area (BSA) is the most commonly used metric for body size indexation of echocardiographic measures, but its use in patients who are underweight or obese is questioned (body mass index (BMI) < 18.5 kg/m2 or ≥ 30 kg/m2, respectively). We aim to use survival analysis to identify an optimal body size indexation metric for echocardiographic measures that would be a better predictor of survival than BSA regardless of BMI. Adult patients with no prior valve replacement were selected from the National Echocardiography Database Australia. Survival analysis was performed for echocardiographic measures both unindexed and indexed to different body size metrics, with 5-year cardiovascular mortality as the primary endpoint. Indexation of echocardiographic measures (left ventricular end-diastolic diameter [n = 230,109] and mass [n = 224,244], left atrial volume [n = 150,540], aortic sinus diameter [n = 90,805], right atrial area [n = 59,516]) by BSA had better prognostic performance vs unindexed measures (underweight: C-statistic 0.655 vs 0.647; normal weight/overweight: average C-statistic 0.666 vs 0.625; obese: C-statistic 0.627 vs 0.613). Indexation by other body size metrics (lean body mass, height, and/or weight raised to different powers) did not improve prognostic performance versus BSA by a clinically relevant magnitude (average C-statistic increase ≤ 0.02), with smaller differences in other BMI subgroups. Indexing measures of cardiac and aortic size by BSA improves prognostic performance regardless of BMI, and no other body size metric has a clinically meaningful better performance.
