Unveiling the mysteries of HER2-low expression in breast cancer: pathological response, prognosis, and expression level alterations

BackgroundThe novel anti-HER2 antibody drug conjugates (ADCs) can effectively improve the long-term survival of patients with HER2-low expression breast cancer. However, pathological responses to neoadjuvant therapy (NAT) within HER2-low expression breast cancer, the relationship between pathological response and prognosis and the transformation of HER2 status are all now poorly understood.MethodsThe patients with HER2-0 and HER2-low expression breast cancer receiving NAT at Harbin Medical University Cancer Hospital between Jan. 2014 and Nov. 2018 were retrospectively explored. HER2 low expression refers to the IHC 1 + or 2 + and FISH negative. The Kappa test was utilized for analyzing the consistency rate of HER2 expression. To evaluate disease-free survival (DFS) and overall survival (OS), this research employed both the Kaplan-Meier analysis and the Cox regression.ResultsIn this study, 178 patients with HER2-0 and 344 patients with HER2-low expression breast cancer were included. In comparison with the HER2-0 group, it is shown that patients in the HER2-low group have more possibility to be younger compared to those 50 years old (P < 0.014), have more premenopausal patients (P < 0.001), a higher proportion of hormone receptor (HR) positive patients (P < 0.001), and less proportion of stage III V patients (P < 0.034). When NAT was finished, the pCR rate became 23.6% in the HER2-0 group while 22.1% in the HER2-low group, and there was also a higher pCR rate in HR- patients in comparison with that in HR + patients (P < 0.01). Considering HER2 expression inconsistency, the overall HER2 inconsistency rate was 30.4% (Kappa = 0.431, P < 0.01). Among patients initially diagnosed as HER2-0, 34% (N = 61) were re-diagnosed as HER2-low after NAT. After stratification by HR expression status, HR+/HER2-0 patients transformed to HER2-low after NAT in 37%, and 32% of HR- patients changed from HER2-0 to HER2-low. In this survival analysis, there were both better DFS rates (P = 0.009) and OS rates (P = 0.026) in the HR-/HER2-low patients in comparison with the HR-/HER2-0 patients, while the HER2-0 and HER2-low patients in the HR + group had no significant survival difference. Additionally, for non-pCR patients, there was better DFS (P = 0.029) and OS (P = 0.038) in the HER2-low group in comparison with that of the HER2-0 group, while no significant survival difference exists between pCR patients.ConclusionAfter HR stratification, there are unique clinical characteristics and prognostic outcomes in HER2-low expression breast cancer, which indicates the potential to become a specific molecular subtype of breast cancer. The significant instability of HER2-low expression status between primary tumor and residual invasive disease suggests that multiple detections of HER2 status should be emphasized in NAT strategies.

Impact of sex on clinical outcomes according to immunologic risk in spousal donor kidney transplantation.

The aim of this study is to investigate the impact of sex on the clinical outcomes of spousal donor kidney transplantation. We analyzed 456 spousal donor kidney transplantation recipients and categorized them into standard or high immunological risk groups according to panel-reactive antibody ≥50% or less. There were 366 recipients in the standard-risk group and 89 recipients in the high-risk group. When comparing biopsy-proven allograft rejection within 1 year from kidney transplantation, husband-to-wife recipients showed significantly higher incidence than wife-to-husband recipients in the high-risk group. By contrast, there was no significant difference between wife-to-husband and husband-to-wife recipients in the standard-risk group. Allograft function recovery was better in husband-to-wife recipients than in wife-to-husband recipients in each group, while husband-to-wife recipients in the high-risk group showed a more rapid decline than other recipients. The long-term patient and allograft survival rates showed no difference between husband-to-wife recipients and wife-to-husband recipients within the same groups. The husband-to-wife recipients with high immunological risk showed a higher risk of biopsy-proven allograft rejection compared to wife-to-husband recipients, so careful monitoring and management may be required.

The Fate of the Aorta after Coarctation Repair: Open Surgical Replacement of Descending Aorta in a High-Volume Unit.

Objectives: Complications after aortic coarctation repair are associated with high mortality and require surgical or endovascular reintervention. For patients unsuitable for endovascular therapies, reoperation remains the only therapeutic option. However, surgical experience and up-to-date follow-up data concerning this overall rare entity in the spectrum of aortic reoperations are still highly limited. Thus, the aim of this study was to analyze the short-term outcomes and long-term survival of patients undergoing surgical descending aorta repair after previous coarctation repair in a high-volume unit. Methods: We present a retrospective single-center analysis of 25 patients who underwent open descending aorta replacement after initial coarctation repair. The surgical history, concomitant cardiovascular malformations, and preoperative characteristics as well as postoperative complications and long-term survival were analyzed. Results: The mean age at operation was 45.4 ± 12.8 years. A proportion of 68% (n = 17) of the patients were male. The most common complication necessitating reoperation after coarctation repair was aneurysm formation (68%) and re-stenosis (16%). The average time between initial repair and reoperation was 26.3 ± 9.9 years. Technical success was achieved in all the operations, while recurrent nerve damage (24%) and bleeding requiring rethoracotomy (20%) were identified as the most common perioperative complications. The one-year mortality was 0% and the overall long-term survival was 88% at 15 years. Conclusions: Open surgical descending aorta replacement can be performed safely and with excellent survival outcomes even in the challenging subgroup of patients after previous coarctation repair. Thus, reoperation should be considered a feasible approach for patients who are unsuitable for endovascular therapies. Nonetheless, concomitant cardiovascular anomalies and frequent preoperations may complicate the redo operation in this patient population.

Neoadjuvant therapy versus upfront surgery in resectable pancreatic cancer: reconstructed patient-level meta-analysis of randomized clinical trials.

Neoadjuvant treatment has shown promising results in patients with borderline resectable pancreatic ductal adenocarcinoma. The potential benefits of neoadjuvant treatment on long-term overall survival in patients with resectable pancreatic ductal adenocarcinoma have not yet been established. The aim of this study was to compare long-term overall survival of patients with resectable pancreatic ductal adenocarcinoma based on whether they received neoadjuvant treatment or underwent upfront surgery. A systematic review including randomized clinical trials on the overall survival outcomes between neoadjuvant treatment and upfront surgery in patients with resectable pancreatic ductal adenocarcinoma was conducted up to 1 August 2023 from PubMed, MEDLINE and Web of Science databases. Patient-level survival data was extracted and reconstructed from available Kaplan-Meier curves. A frequentist one-stage meta-analysis was employed, using Cox-based models and a non-parametric method (restricted mean survival time), to assess the difference in overall survival between groups. A Bayesian meta-analysis was also conducted. Five randomized clinical trials comprising 625 patients were included. Among patients with resectable pancreatic ductal adenocarcinoma, neoadjuvant treatment was not significantly associated with a reduction in the hazard of death compared with upfront surgery (shared frailty HR 0.88, 95% c.i. 0.72 to 1.08, P = 0.223); this result was consistent in the non-parametric restricted mean survival time model (+2.41 months, 95% c.i. -1.22 to 6.04, P < 0.194), in the sensitivity analysis that excluded randomized clinical trials with a high risk of bias (shared frailty HR 0.91 (95% c.i. 0.72 to 1.15; P = 0.424)) and in the Bayesian analysis with a posterior shared frailty HR of 0.86 (95% c.i. 0.70 to 1.05). Neoadjuvant treatment does not demonstrate a survival advantage over upfront surgery for patients with resectable pancreatic ductal adenocarcinoma.

Clinical features and surgical strategy of retroperitoneal liposarcoma involving the kidney capsule: a retrospective comparative cohort study.

Valid and generalizable data on the clinical features and surgical strategies for retroperitoneal liposarcoma (LPS) involving the kidney capsule remain scarce. This study aimed to investigate the clinical characteristics, morbidity, mortality, and long-term survival of patients with retroperitoneal LPS involving the kidney capsule. The authors analyzed a prospectively maintained database of patients who underwent surgical resection for retroperitoneal LPS between 2015 and 2020. The patients were categorized into kidney capsule or no kidney capsule groups based on the presence or absence of kidney capsule involvement. A kidney-sparing strategy for retroperitoneal LPS involving the kidney capsule was developed. The primary outcome measure was overall survival (OS). The cumulative event probability curve was estimated using the Kaplan-Meier, and differences between groups using the Log-Rank. The study population consisted of 128 patients-54 with and 74 without kidney capsule involvement. Of these patients, 70 were female (54.7%) and 58 were male (45.3%), with a median age of 55. The median follow-up duration was 35 months. Postoperative morbidity, mortality, length of hospital stay, length of ICU stay, OS, and recurrence-free survival (RFS) did not differ significantly between the groups. Eleven patients developed postoperative acute kidney injury (AKI), and one patient required dialysis during the follow-up period. In multivariable logistic regression analysis, only nephrectomy was independently associated with postoperative AKI. Subgroup analysis of patients with kidney capsule involvement showed that nephrectomy did not improve OS or RFS but significantly decreased postoperative estimated glomerular filtration rate. Nephrectomy was associated with an increased risk of postoperative AKI after retroperitoneal LPS resection. A kidney-sparing strategy for retroperitoneal LPS involving the kidney capsule achieved optimal clinical outcomes.

555. SUPRACLAVICULAR NODE INVOLVEMENT, A NODAL OR METASTATIC DISEASE? - A 10-YEAR EXPERIENCE IN ESOPHAGEAL CARCINOMA AT A TERTIARY REFERRAL CENTRE

Abstract Background Despite the advance in neoadjuvant chemothepray/chemoradiotherapy and favourable outcomes of surgical management in supraclavicular lymph node (SCLN) involvement reported in recent studies, the latest AJCC/UICC TMN classification still regards SCLN metastasis as extra-regional i.e Stage IVB (M1) disease. The role of SCLN dissection and surgical management remain controversial. At National University Hospital of the present study, bilateral supraclavicular lymphadenectomy is routinely performed for resectable thoracic ESCC. The aim of this retrospective cohort study is to investigate the long-term outcome of surgical management in pathological SCLN metastasis and its survival benefit comparing to Stage IIB-IVA diseases. Methods Patients with ESCC who underwent esophagectomy and 3-field lymphadenectomy with curative intent between January 2013 and January 2023 at the single centre were included; cases of salvage esophagectomy post-definitive concurrent chemoradiotherapy, palliative resections, and concurrent head and neck cancers were excluded. Neoadjuvant treatments were considered in cases staged clinically as T2 and/or N1 or greater. Pathological status of lymph nodes was recorded according to JES classification. Demographics and prognostic factors were examined using univariant analysis of overall survival (OS). Patients with SCLN metastases and other LN involvements were compared and OS were analysed using Kaplan-Meier method. Results 544 patients were included. 183 had one or more pathological LN metastasis (pN1:126, pN2 46, and PN3: 11) in which 55 patients had SCLN metastasis. Patients with LN metastasis had poorer prognosis than those without (pN0) with a Hazard Ratio (HR) of 2.68 (95% CI, 1.12-3.40, p&amp;lt;0.01); similar pattern was seen in patients with SCLN metastasis (HR 2.28, p&amp;lt;0.01). The 3-year and 5-year OS of patients with SCLN metastasis was 18.5% and 11.6% respectively whereas those of other LN metastasis was 21.4% and 15.8%; the difference between the groups was not statistically significant (p=0.525) (graph 1). Conclusion Lymph node status (pN) is a well-recognised prognostic factor as reaffirmed, however, within the pN positive cohort, long-term survival of patients with SCLN metastasis, considered as stage IVB (M1), was comparable (p&amp;lt;0.05) to those with other LN metastases. This supports the survival benefit of surgical resection with neoadjuvant therapy in SCLN metastases as following nodal disease treatment algorithm; further evaluation including systemic therapy and lymph node sub-group analysis is being conducted. Whilst randomised controlled trials such as Japanese JCOG2013 provides level I evidence, the present study provides complementary real-world experience for SCLN dissection.

Prognostic value of Glasgow Prognostic Score and its modified scores on 5-year outcome in patients with coronary heart disease undergoing percutaneous coronary intervention

BackgroundGlasgow Prognostic Score (GPS) and its modified counterparts, including the modified GPS (mGPS) and hsCRP-modified GPS (hs-mGPS), are widely used inflammatory indices in clinical settings. Inflammation has gained increased attention in the context of coronary heart disease (CHD); however, its long-term predictive value in patients with CHD remains uncertain. ObjectiveThis study aimed to assess the predictive values of GPS, mGPS, and hs-mGPS for long-term survival in patients following percutaneous coronary intervention (PCI). MethodsConsecutive 10,724 PCI patients were enrolled in 2013. The primary endpoint was 5-year all-cause death. ResultsThis study included 8,909 patients. Individuals with high GPS, mGPS, and hs-mGPS scores exhibited a significantly higher risk of all-cause death compared to those with low scores (all P < 0.05). All three indices (GPS, mGPS, and hs-mGPS) demonstrated predictive values for all-cause death, albeit with relatively low area under the curve values of 0.534, 0.522, and 0.545, respectively. Furthermore, we refined the hs-mGPS using cutoffs (hsCRP at 2 mg/L and albumin at 40 g/L) which are better suited for these patients, to establish the CHD-hs-mGPS. This modification significantly improved the prediction of all-cause death, outperformed the mGPS and demonstrated numerical superiority over both the GPS and hs-mGPS. Notably, only CHD-hs-mGPS exhibited a predictive value for both the ACS and non-ACS subgroups. ConclusionIn patients with CHD who underwent PCI, GPS, mGPS, and hs-mGPS demonstrated significant long-term predictive values for all-cause death. Our parameter-adjusted score, the CHD-hs-mGPS, is applicable to a broad population and moderately enhances the predictive accuracy, facilitating the early identification of patients at high risk of long-term death.

273. PERIOPERATIVE BLOOD TRANSFUSIONS AND SURVIVAL IN GASTROESOPHAGEAL CANCERS – A SWEDISH POPULATION-BASED STUDY

Abstract Background Blood transfusions have been associated with decreased long-term survival in cancer patients, possibly due to immunological factors. This cohort study aimed to investigate associations, if any, between perioperative transfusions and survival in gastroesophageal cancer patients. Methods A population-based cohort study was conducted based on the National Registry for Esophageal and Gastric cancer (NREV), which harbors clinical data including given transfusions. All patients resected for esophageal or gastric cancer in Sweden, between 2017 and 2022, were included and their survival was acquired from the Swedish Cause of Death Registry. Multivariable Cox regression was used to calculate hazard ratios (HR) with 95% confidence intervals (CI), adjusted for confounders (age, American Society of Anesthesiologist class, access of surgery and pathological TNM stage) Results Of 1,368 patients, 227 patients (17%) received perioperative transfusions. Transfusion was associated with an increased risk of all-cause mortality within 3 years of surgery (HR 1.48 95% CI 1.17-1.91). Kaplan-Meier curves depicted worse crude survival in patients having received peroperative transfusion (Figure 1). To exclude the effects of surgery-related postoperative complications on short-term mortality, a sensitivity analysis was performed, excluding patients who died within 30 days of resection, and found that the impact of transfusions on survival remained. Conclusion Perioperative blood transfusions might have a negative impact on survival in patients who undergo gastroesophageal cancer surgery.

Exploration of Key Genes Combining with Immune Infiltration Level andTumor Mutational Burden in Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is a lethal malignancy due to its heterogeneity and aggressive behavior. Recently, somatic mutations and tumor cell interactions with the surrounding tumor immune microenvironment (TIME) have been reported to participate in HCC carcinogenesis and predict HCC progression. In this study, we aimed to investigate the association between tumor mutational burden (TMB) and TIME in HCC. Additionally, we sought to identify differentially expressed genes (DEGs) associated with HCC prognosis and progression. The expression, clinical, and mutational data were downloaded from the cancer genome atlas (TCGA) database. The immune infiltration levels and TMB levels of the HCC samples were estimated and the samples were divided into immune cluster (ICR)-1 and 2 based on immune infiltration score and high and low TMB groups based on TMB score. Thereafter, differential gene expression analysis was conducted to identify the DEGs in the ICR1/2 and high/low TMB groups, and the intersecting DEGs were selected. Thereafter, Cox regression analysis was performed on 89 significant DEGs, among which 19 were associated with prognosis. These 19 DEGs were then used to construct a prognostic model based on their expression levels and regression coefficients. Thereafter, we analyzed the DEGs in mutant and wildtype TP53 HCC samples and identified high BCL10 and TRAF3 expression in the mutant TP53 samples. BCL10 and TRAF3 expression was detected by real-time quantitative reverse transcription PCR and immunohistochemistry, and their clinical correlation, biological function, and immune infiltration levels were analyzed by chi-square analyses, Gene Set Enrichment Analysis (GSEA), and "ssGSEA", respectively. The results of our study revealed that immune infiltration level was correlated with TMB and that they synergistically predicted poor prognosis of HCC patients. DEGs enriched in immune-related pathways could serve as indicators of immunotherapy response in HCC. Among these DEGs, BCL10 and TRAF3 were highly expressed in HCC tissues, especially in the mutant TP53 group, and they co-operatively exhibited immunological function, thereby affecting HCC progression and prognosis. In this study, we identified BCL10 and TRAF3 as potential prognostic indicators in HCC patients. Additionally, we found that BCL10 and TRAF3 influence TMB and TIME in HCC patients and can be used for the development of immune-based therapies for improving the long-term survival of HCC patients.

Long-term outcomes and risk factors for early bacterial infection after pediatric liver transplantation: a prospective cohort study.

Liver transplantation (LT) is the most efficient treatment for pediatric patients with end-stage liver diseases, while bacterial infection is the leading reason for post-transplant mortality. The present study is to explore the outcomes and risk factors of early bacterial infection (within 1 months) after pediatric LT. In this prospective cohort study, 1316 pediatric recipients [median (IQR) age: 9.1 (6.3-28.0) months; male: 48.0%; median (IQR) follow-up time: 40.6 (29.1-51.4) months] who received LT from September 2018 to April 2022 were included. Bacterial culture samples such as sputum, abdominal drainage, blood, and so on were collected when recipients were presented with infective symptoms. Kaplan-Meier analysis was applied to estimate the long-term survival rates and logistic regression was used to identify independent risk factors. To explore the role of pretransplant rectal swab culture (RSC) in reducing post-transplant bacterial infection rate, 188 infant LT recipients [median (IQR) age: 6.8 (5.5-8.1) months; male: 50.5%] from May 2022 to September 2023 were included. Log-binomial regression was used to measure the association of pretransplant RSC screening and post-transplant bacterial infection. The 'Expectation Maximization' algorithm was used to impute the missing data. Bacterial infection was the primary cause for early (38.9%) and overall mortality (35.6%) after pediatric LT. Kaplan-Meier analysis revealed inferior 1-year and 5-year survival rates for recipients with post-transplant bacterial infection (92.6 vs. 97.1%, 91.8 vs. 96.4%, respectively; P <0.001). Among all detected bacteria, Staphylococcus spp. (34.3%) and methicillin-resistant coagulase-negative Staphylococci (43.2%) were the dominant species and multidrug resistant organisms, respectively. Multivariable analysis revealed that infant recipients [adjusted odds ratio (aOR) 1.49; 95% CI: 1.01-2.20], male recipients (aOR, 1.43; 95% CI: 1.08-1.89), high graft-to-recipient weight ratio (aOR, 1.64; 95% CI: 1.17-2.30), positive post-transplant RSC (aOR, 1.45; 95% CI: 1.04-2.02) and nasopharyngeal swab culture (aOR 2.46; 95% CI: 1.72-3.52) were independent risk factors for early bacterial infection. Furthermore, RSC screening and antibiotic prophylaxis before transplantation could result in a relatively lower post-transplant infection rate, albeit without statistical significance (adjusted RR, 0.53; 95% CI: 0.25-1.16). In this cohort study, post-transplant bacterial infection resulted in an inferior long-term patient survival rate. The five identified independent risk factors for post-transplant bacterial infection could guide the prophylaxis strategy of post-transplant bacterial infection in the future. Additionally, pretransplant RSC might decrease post-transplant bacterial infection rate.

Vliv polymorfizmů PNPLA3 rs738409 a TM6SF2 rs58542926 dárce a příjemce na dlouhodobé přežívání pacientů po transplantaci jater

Summary Introduction: The variants rs738409 c.444C&gt;G (p.I148M) in patatin-like phospholipase domain-containing 3 (PNPLA3) and rs58542926 c.499G&gt;A (p.E167K) in TM6SF2 (transmembrane 6 superfamily member 2) are significant genetic risk factors of development and progression of non-alcoholic fatty liver disease (NAFLD). In both variants, increased liver-specific mortality was described, while the impact on all-cause mortality was not proved. The aim of the study was to evaluate the impact of PNPLA3 rs738409 and TM6SF2 rs58542926 genotypes of the donor and recipient respectively on long-term patient survival after LT. Methods: We evaluated long-term patient survival in a cohort of 268 adult LT recipients, in whom PNPLA3 rs738409 and TM6SF2 rs58542926 genotypes of the donor and recipient respectively were available and steatosis was evaluated in liver graft biopsy 6–30 months after LT. The median fol low-up was 17 years. The Kaplan-Meier model was used for the survival estimates and the Cox proportional hazard model was used to assess the predictive value of the chosen variables. Results: Increased recipient age (P &lt; 0.001), male sex (P = 0.014), alcoholic (P = 0.021) or HCV (P = 0.042) etiology of liver cirrhosis, and presence of hepatocellular carcinoma (P = 0.009) negatively influenced long-term patient survival after LT. PNPLA3 rs738409 and TM6SF2 rs58542926 genotypes of the recipient and donor respectively had no effect on patient survival. Conclusion: Although PNPLA3 c.444G and TM6SF2 c.499A variants of the donor increase the risk of steatosis of the liver graft after LT, we did not prove a negative impact of these genotypes of the donor and recipient on long-term patient survival after LT.

A scoring system based on inflammatory and nutritional indicators to predict the long-term survival of patients with non-metastatic nasopharyngeal carcinoma

To develop a simple scoring system based on baseline inflammatory and nutritional markers to predict the long-term prognosis of patients with nasopharyngeal carcinoma (NPC). Conducted a retrospective analysis of clinical data from 1024 newly diagnosed non-metastatic NPC patients. A total of 15 pre-treatment inflammatory and nutritional markers were collected as candidate variables. Receiver operating characteristic (ROC) curves were used to determine the optimal cutoff points for each parameter. Survival analysis was performed using Kaplan–Meier method and Cox regression analysis. Besides, the Inflammation Nutrition Risk Score (INRS) was calculated for each patient by assigning each independent prognostic factor a score of 1. Multivariate Cox regression analysis showed that serum albumin (ALB), systemic immune-inflammation index, and monocyte count (M) were independent prognostic factors for OS (P < 0.05). Survival analysis showed that higher INRS was associated with a worsened prognosis. Patients in the high-risk group had shorter OS than in the low-risk group. In the training group, the 3-, 5-, and 8-years OS rates for the low-risk group versus high-risk group were 92.5% versus 87.8%, 87.4% versus 75.1%, and 84.6% versus 62.2%, respectively (P < 0.05). In the validation group, the 3-, 5-, and 8-years OS rates for the low-risk group vs. high-risk group were 95.0% versus 86.4%, 92.1% versus 82.2%, and 89.5% versus 74.3%, respectively (P < 0.05). Further subgroup analysis showed a significant difference in the OS between the high-risk group and low-risk group in patients with locally advanced disease (P < 0.05). The ROC curve demonstrated that INRS had a similar predictive value for long-term survival in NPC patients compared to TNM staging and serum EBV-DNA levels. Pretreatment ALB, M, and SIRI are independent prognostic factors for long-term survival in patients with NPC. INRS constructed based on these three factors can serve as a long-term prognostic indicator for NPC.

Association between renal dysfunction and outcomes of lung cancer: A systematic review and meta‑analysis.

Renal insufficiency and/or chronic kidney disease are common comorbidities in patients with lung cancer, potentially affecting their prognosis. The aim of the present study was to assess the existing evidence on the association between renal insufficiency (RI)/chronic kidney disease (CKD) and the overall survival (OS) and disease-free survival (DFS) of patients with lung cancer (LC). Comprehensive electronic searches in the PubMed, Embase and Scopus databases were performed for observational cohort and case-control studies and randomized controlled trials that investigated the association between RI/CKD and the OS and/or DFS of patients with LC. Random-effect models were used, and the combined effect sizes were reported as either standardized mean differences or relative risks, along with 95% confidence intervals (CI). A total of 10 studies were included. The duration of follow-up in the included studies ranged from 12 months to 5 years. Compared with patients with normal renal function, patients with LC with RI/CKD had worse OS rates [hazard ratio (HR), 1.38; 95% CI, 1.16-1.63] but similar DFS rates (HR, 1.12; 95% CI, 0.75-1.67) at follow-up. Subgroup analysis demonstrated a significant association between poor OS and RI/CKD in patients with stage I/II LC [HR, 1.76; 95% CI, 1.30-2.37] but not in patients with stage III/IV LC [HR, 1.18; 95% CI, 0.91, 1.54]. Furthermore, irrespective of the treatment modality i.e., surgery [HR, 1.78; 95% CI, 1.40-2.27] or medical management [HR, 1.37; 95% CI, 1.25-1.50], RI/CKD was notably associated with a poor OS at follow-up. The findings of the present study underscore the adverse impact of RI/CKD on the long-term survival of patients with LC.

AWGC2023 cachexia consensus as a valuable tool for predicting prognosis and burden in Chinese patients with cancer.

The Asian Working Group for Cachexia (AWGC) proposed the first consensus report on diagnostic criteria for cachexia in Asians in 2023. However, the current consensus lacks cohort evidence to validate its effectiveness and practicality. We aimed to explore the value of the AWGC2023 criteria for predicting the prognosis and medical burden of patients with cancer through a retrospective post hoc cross-sectional analysis of the Investigation on Nutrition Status and its Clinical Outcome of Common Cancers (INSCOC) project in China. Cox regression analyses were performed to assess the independent association between cachexia and long-term survival. We utilized C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR), inflammatory burden index (IBI), albumin (ALB) and Glasgow prognostic score (GPS) as diagnostic markers for cachexia, designating them as CRP-based cachexia, NLR-based cachexia, IBI-based cachexia, ALB-based cachexia and GPS-based cachexia, respectively. Additionally, we diagnosed cachexia using body mass index (BMI) cutoff values of 18.5, 20, 21 and 22kg/m2, respectively, and subsequently compared their prognostic predictive value through Harrell's concordance index (C-index). Logistic regression models were used to assess the association between cachexia and medical burden. A total of 5426 patients with cancer were enrolled in this study. Cox regression analysis confirmed that cachexia based on the AWGC2023 criteria was an independent predictor of long-term survival in patients with cancer. Patients with cachexia had significantly poorer long-term survival than patients without cachexia (66.4% vs. 49.7%, P<0.001). Inflammatory biomarker-based cachexia was as an independent predictor of prognosis in patients with cancer, with inflammatory burden index (IBI)-based cachexia demonstrating the optimal prognostic discriminatory ability. The C-index indicated that cachexia based on BMI cutoff values of 18.5, 20, and 22kg/m2 did not perform as well as a BMI cutoff value of 21kg/m2. Logistic regression models revealed that using the AWGC2023 criteria, patients with cachexia had a 16.6% higher risk of prolonged hospitalization and a 16.0% higher risk of high medical expenses than patients without cachexia. The AWGC2023 criteria represent a valuable tool for predicting survival and medical burden among Chinese patients with cancer. Encouragement for further validation in other Asian populations is warranted for the AWGC2023 criteria.

Myosteatosis and muscle loss impact liver transplant outcomes in male patients with hepatocellular carcinoma.

Sarcopenia is associated with unfavourable long-term survival in patients undergoing liver transplantation (LT) for hepatocellular carcinoma (HCC). However, the impact of myosteatosis and muscle loss on patient prognosis has not been investigated. Seven hundred fifty-six HCC patients who received LT at 3 transplant centres were included. Computed tomography (CT) images of recipients were collected to measure skeletal muscle index (SMI) and skeletal muscle radiodensity (SMRA). The impact of myosteatosis on the prognosis of sarcopenic and non-sarcopenic patients was studied separately. Muscle status was evaluated based on the presence of sarcopenia and myosteatosis. The muscle loss of 342 males was calculated as the relative change of SMI between pre- and post-LT evaluations. Cox regression models were used to identify predictors of overall survival (OS) and recurrence-free survival (RFS). The study comprised 673 males and 83 females. The median follow-up time was 31months (interquartile range, 19-43months). Prior to LT, 267 (39.7%) and 187 (27.8%) males were defined as sarcopenic (low-SMI) and myosteatotic (low-SMRA), respectively. For sarcopenic recipients, the presence of myosteatosis was followed by a 23.6% decrease in 5year OS (P<0.001) and a 15.0% decrease in 5year RFS (P=0.014). Univariate and multivariate analyses revealed that muscle status was an independent predictor of OS [hazard ratio (HR), 1.569; 95% confidence interval (CI), 1.317-1.869; P<0.001] and RFS (HR, 1.369; 95% CI, 1.182-1.586; P<0.001). Postoperatively, a muscle loss >14.2% was an independent risk factor for poor OS (HR, 2.286; 95% CI, 1.358-3.849; P=0.002) and RFS (HR, 2.219; 95% CI, 1.418-3.471; P<0.001) in non-sarcopenic recipients (N=209). Pre-transplant myosteatosis aggravated the adverse impact of sarcopenia on liver transplant outcomes in male HCC patients. Post-transplant muscle loss might assist in prognostic stratification of recipients without pre-existing sarcopenia, intriguing new insights into individualized management.

Association Between Sarcopenia, Clinical Outcomes, and Survival in Patients with Extensive-Stage Small Cell Lung Cancer Treated with First-Line Immunochemotherapy: A Prospective Cohort Study.

To investigate the association between sarcopenia, short-term efficacy, and long-term survival in patients with extensive small-cell lung cancer (SCLC) treated with standard first-line immunochemotherapy. A total of 63 patients initially diagnosed with extensive-stage small cell lung cancer were enrolled in the prospective study from December 1, 2020 to December 31, 2022. The clinical characteristics, body composition, blood test results, and image data were obtained before treatment. Patients were divided into sarcopenia and non-sarcopenia groups according to the diagnostic criteria of the Asian Sarcopenia Working Group 2019. The primary outcome was overall survival (OS) and comprehensive survival analyses were performed. Secondary outcomes included short-term efficacy and adverse events associated with first-line immunochemotherapy. The median age of the 63 patients enrolled in our study was 63.0 years (40-80 years). The incidence of sarcopenia was 19.0% (12/63) in patients with extensive SCLC. Compared with non-sarcopenia patients, extensive-stage SCLC patients with sarcopenia were significantly older (69.0 vs. 62.0, P = 0.017), and had lower body mass index (BMI) (20.29 vs. 24.27, P < 0.001), hand grip strength (HGS) (20.42 vs. 30.75, P < 0.001), and albumin (35.9 vs. 41.40, P < 0.001). The objective response rate after two cycles of standard first-line immunochemotherapy in the sarcopenia group was lower than in the non-sarcopenia group (30.0 vs. 78.9%, P = 0.012). There was no significant difference in chemotherapy-related hematological toxicity between the two groups. During a median follow-up of 15 months (3-33 months), patients with extensive SCLC had a median OS of 24 months, with 1-year survival of 75% and 2-year survival of 52%, respectively. Compared to non-sarcopenia patients, the median OS in the sarcopenia group was significantly shorter (9 vs. 24 months, P = 0.0014). Multivariate Cox analysis showed that sarcopenia was an independent risk factor for OS in patients with extensive SCLC (HR = 4.993, 95%CI = 1.106-22.538, P = 0.037). Patients with Extensive SCLC and sarcopenia had worse clinical outcomes and shorter OS. Sarcopenia is a prognostic factor affecting first-line treatment efficacy and long-term survival of patients with SCLC in the era of immunotherapy.

Prognostic factors in patients with intrahepatic cholangiocarcinoma

Intrahepatic cholangiocarcinoma (ICC) is the second commonly-seen liver malignancy and one of the most fatal cancers in Taiwan. Survival after diagnosis of ICC remains poor. This study aimed to investigate the survival and prognostic factors in patients with ICC. All patients with newly diagnosed ICC during 2004 to 2018 were identified from a national cancer database and followed until December 2020. Estimates of overall survival (OS) were conducted using the Kaplan–Meier method and Cox proportional hazards model. Hazard ratios with 95% confidence intervals were calculated. Initially, 7940 patients with ICC disease (stage IV: 55.6%, 4418/7940) were eligible for this study. Only 32.3% (2563/7940) patients with ICC underwent liver resection. After Propensity score matching, 969 pairs (N = 1938) of patients were matched and selected (mean age 62.8 ± 11.0 years, 53.1% were male, 29.7% had cirrhosis). The median follow-up time was 80.0 months (range 25–201 months). The 3-, 5-year OS rates were 44.0%, 36.4% in the surgical group and 26.0%, 23.7% in the non-surgical group, respectively. Surgery, young patients (≤ 54 years), small tumor size, no vascular invasion and chemotherapy were associated with better OS in patients with stages I–III disease. Surgery benefit was maximum in stage I disease followed by stage II. In patients with stage IV disease, factors such as surgery, young patients (≤ 64 years), single tumor, and no vascular invasion were associated with better OS. Chemotherapy was insignificantly associated with better OS. Long-term survival in patients with ICC is very poor. Compared to non-surgical patients, surgery conveys approximately 18% and 12% better OS rates at 3-year and 5-year, respectively. Early detection and surgical intervention may improve OS substantially in patients with ICC.
