RESUMEN
BACKGROUND: Evidence-based practice in community-acquired pneumonia often assumes an accurate initial diagnosis. OBJECTIVE: To examine the evolution of pneumonia diagnoses among patients hospitalized from the emergency department (ED). DESIGN: Retrospective nationwide cohort. SETTING: 118 U.S. Veterans Affairs medical centers. PATIENTS: Aged 18 years or older and hospitalized from the ED between 1 January 2015 and 31 January 2022. MEASUREMENTS: Discordances between initial pneumonia diagnosis, discharge diagnosis, and radiographic diagnosis identified by natural language processing of clinician text, diagnostic coding, and antimicrobial treatment. Expressions of uncertainty in clinical notes, patient illness severity, treatments, and outcomes were compared. RESULTS: Among 2 383 899 hospitalizations, 13.3% received an initial or discharge diagnosis and treatment of pneumonia: 9.1% received an initial diagnosis and 10.0% received a discharge diagnosis. Discordances between initial and discharge occurred in 57%. Among patients discharged with a pneumonia diagnosis and positive initial chest image, 33% lacked an initial diagnosis. Among patients diagnosed initially, 36% lacked a discharge diagnosis and 21% lacked positive initial chest imaging. Uncertainty was frequently expressed in clinical notes (58% in ED; 48% at discharge); 27% received diuretics, 36% received corticosteroids, and 10% received antibiotics, corticosteroids, and diuretics within 24 hours. Patients with discordant diagnoses had greater uncertainty and received more additional treatments, but only patients lacking an initial pneumonia diagnosis had higher 30-day mortality than concordant patients (14.4% [95% CI, 14.1% to 14.7%] vs. 10.6% [CI, 10.4% to 10.7%]). Patients with diagnostic discordance were more likely to present to high-complexity facilities with high ED patient load and inpatient census. LIMITATION: Retrospective analysis; did not examine causal relationships. CONCLUSION: More than half of all patients hospitalized and treated for pneumonia had discordant diagnoses from initial presentation to discharge. Treatments for other diagnoses and expressions of uncertainty were common. These findings highlight the need to recognize diagnostic uncertainty and treatment ambiguity in research and practice of pneumonia-related care.

RESUMEN
BACKGROUND AND AIMS: The concept of textbook outcomes (TOs) has gained increased attention as a critical metric to assess the quality and success of outcomes following complex surgery. A simple yet effective scoring system was developed and validated to predict risk of not achieving textbook outcomes (non-TOs) following hepatectomy for hepatocellular carcinoma (HCC). METHODS: Using a multicenter prospectively collected database, risk factors associated with non-TO among patients who underwent hepatectomy for HCC were identified. A predictive scoring system based on factors identified from multivariate regression analysis was used to risk stratify patients relative to non-TO. The score was developed using 70 % of the overall cohort and validated in the remaining 30 %. RESULTS: Among 3681 patients, 1458 (39.6 %) failied to experience a TO. Based on the derivation cohort, obesity, American Society of Anaesthesiologists score(ASA score), Child-Pugh grade, tumor size, and extent of hepatectomy were identified as independent predictors of non-TO. The scoring system ranged from 0 to 10 points. Patients were categorized into low (0-3 points), intermediate (4-6 points), and high risk (7-10 points) of non-TO. In the validation cohort, the predicted risk of developing non-TOs was 39.0 %, which closely matched the observed risk of 39.9 %. There were no differences among the predicted and observed risks within the different risk categories. CONCLUSIONS: A novel scoring system was able to predict risk of non-TO accurately following hepatectomy for HCC. The score may enable early identification of individuals at risk of adverse outcomes and inform surgical decision-making, and quality improvement initiatives.
RESUMEN
OBJECTIVE: This study aims to conduct an extensive analysis of autoimmune bullous diseases, particularly pemphigus vulgaris and bullous pemphigoid, in Shanghai, China, from 2016 to 2023. It seeks to understand the demographic profiles, comorbidities, mortality rates, risk factors, and socioeconomic impacts associated with autoimmune bullous disease. METHODS: A cross-sectional study design was employed, enrolling 1,072 patients. Diagnostic measures included clinical manifestations, histopathology, direct immunofluorescence, and serologic tests. The study also involved a detailed socioeconomic analysis and evaluation of occupational risks. RESULTS: The findings highlight a significant occupational risk in industries requiring enhanced safety measures, with a notable prevalence of autoimmune bullous disease among workers in these sectors. A considerable portion of the patients were from low-income backgrounds with limited literacy, indicating the economic burden of autoimmune bullous disease. A key discovery of the study is the potential pathological link between autoimmune bullous disease and interstitial lung disease. CONCLUSION: This research, one of the first comprehensive studies on autoimmune bullous disease in China, underscores the need for targeted healthcare strategies and further investigation into autoimmune bullous disease, particularly its relationship with interstitial lung disease.
RESUMEN
BACKGROUND & AIMS: With the rising prevalence of non-alcoholic fatty liver disease (NAFLD) as a significant etiology for hepatocellular carcinoma (HCC), lean NAFLD-HCC has emerged as a specific distinct subtype. This study sought to investigate long-term outcomes following curative-intent hepatectomy for early-stage NAFLD-HCC among lean patients compared with overweight and obese individuals. METHODS: A multicenter retrospective analysis was used to assess early-stage NAFLD-HCC patients undergoing curative-intent hepatectomy between 2009 and 2022. Patients were stratified by preoperative body mass index (BMI) into the lean (<23.0 kg/m2), overweight (23.0-27.4 kg/m2) and obese (≥27.5 kg/m2) groups. Study endpoints were overall survival (OS) and recurrence-free survival (RFS), which were compared among groups. RESULTS: Among 309 patients with NAFLD-HCC, 66 (21.3 %), 176 (57.0 %), and 67 (21.7 %) were lean, overweight, and obese, respectively. The three groups were similar relative to most liver, tumor, and surgery-related variables. Compared with overweight patients (71.3 % and 55.6 %), the lean individuals had a worse 5-year OS and RFS (55.4 % and 35.1 %, P = 0.017 and 0.002, respectively), which were comparable to obese patients (48.5 % and 38.2 %, P = 0.939 and 0.442, respectively). After adjustment for confounding factors, multivariable Cox-regression analysis identified that lean bodyweight was independently associated with decreased OS (hazard ratio: 1.69; 95 % confidence interval: 1.06-2.71; P = 0.029) and RFS (hazard ratio: 1.72; 95 % confidence interval: 1.17-2.52; P = 0.006) following curative-intent hepatectomy for early-stage NAFLD-HCC. CONCLUSIONS: Compared with overweight patients, individuals with lean NAFLD-HCC had inferior long-term oncological survival after hepatectomy for early-stage NAFLD-HCC. These data highlight the need for examination of the distinct carcinogenic pathways of lean NAFLD-HCC and its potential consequences in HCC recurrence.
RESUMEN
Background: The application of Pringle maneuver (PM) during hepatectomy reduces intraoperative blood loss and the need for perioperative transfusion, but its effect on long-term recurrence and survival for patients with hepatocellular carcinoma (HCC) remains controversial. We sought to determine the association between the application of PM and post-hepatectomy oncologic outcomes for patients with HCC. Methods: Patients who underwent curative hepatectomy for HCC at 9 Chinese hospitals from January 2010 to December 2018 were identified. Using two propensity score methods [propensity score matching (PSM) and inverse probability of treatment weight (IPTW)], cumulative recurrence rate and cancer-specific mortality (CSM) were compared between the patients in the PM and non-PM groups. Multivariate competing-risks regression models were performed to adjust for the effect of non-cancer-specific mortality and other prognostic risk factors. Results: Of the 2,798 included patients, 2,404 and 394 did and did not adopt PM (the PM and non-PM groups), respectively. The rates of intraoperative blood transfusion, postoperative 30-day mortality and morbidity were comparable between the two groups (all P>0.05). In the PSM cohort by the 1:3 ratio, compared to 382 patients in the non-PM group, 1,146 patients in the PM group also had the higher cumulative 5-year recurrence rate and CSM (63.9% and 39.1% vs. 55.3% and 31.6%, both P<0.05). Similar results were also yielded in the entire cohort and the IPTW cohort. Multivariate competing-risks regression analyses demonstrated that no application of the PM was independently associated with lower recurrence rate and CSM based on various analytical cohorts [hazard ratio (HR), 0.82 and 0.77 in the adjusted entire cohort, HR 0.80 and 0.73 in the PSM cohort, and HR 0.80 and 0.76 in the IPTW cohort, respectively]. Conclusions: The findings suggested that no application of PM during hepatectomy for patients with HCC reduced the risk of postoperative recurrence and cancer-specific death by approximately 20-25%.
RESUMEN
BACKGROUND: The burgeoning demand for hepatectomy in elderly patients with hepatocellular carcinoma (HCC) necessitates improved perioperative care. Geriatric populations frequently experience functional decline and frailty, predisposing them to adverse postoperative outcomes. The Barthel Index serves as a reliable measure for assessing functional capacity, and this study evaluates its impact on surgical textbook outcomes (TOs) in elderly HCC patients. METHODS: A multicenter retrospective cohort study analyzed elderly patients (≥70 years) following hepatectomy for HCC between 2013 and 2021. Utilizing a Barthel Index cut-off value of 85, patients were divided into two groups: with and without preoperative functional decline and frailty. The primary outcome was the rate of TO, encompassing seven criteria. TO rates were compared between groups, and multivariate logistic regression analyses identified independent risks for achieving TOs. RESULTS: Of 497 elderly patients, 157 (31.6 â%) exhibited preoperative functional decline and frailty (Barthel Index score <85). The overall TO rate was 58.6 â%. Patients with preoperative Barthel Index score <85 had significantly lower TO rates compared to patients with score ≥85 (29.3 â% vs. 72.1 â%, P â< â0.001). Multivariate analysis revealed preoperative Barthel Index score <85 as an independent risk for achieving TO (odds ratio 3.413, 95 â% confidence interval 1.879-6.198, P â< â0.001). Comparable results were observed in the subgroups of patients undergoing open and laparoscopic hepatectomy. CONCLUSION: Preoperative Barthel Index-based assessment of functional decline and frailty significantly predicts TOs following hepatectomy in elderly HCC patients, enabling identification of high-risk patients and informing preoperative management and postoperative care within geriatric oncology.
RESUMEN
Immunohistochemistry (IHC) is used to guide treatment decisions in multiple cancer types. For treatment with checkpoint inhibitors, programmed death ligand 1 (PD-L1) IHC is used as a companion diagnostic. However, the scoring of PD-L1 is complicated by its expression in cancer and immune cells. Separation of cancer and noncancer regions is needed to calculate tumor proportion scores (TPS) of PD-L1, which is based on the percentage of PD-L1-positive cancer cells. Evaluation of PD-L1 expression requires highly experienced pathologists and is often challenging and time-consuming. Here, we used a multi-institutional cohort of 77 lung cancer cases stained centrally with the PD-L1 22C3 clone. We developed a 4-step pipeline for measuring TPS that includes the coregistration of hematoxylin and eosin, PD-L1, and negative control (NC) digital slides for exclusion of necrosis, segmentation of cancer regions, and quantification of PD-L1+ cells. As cancer segmentation is a challenging step for TPS generation, we trained DeepLab V3 in the Visiopharm software package to outline cancer regions in PD-L1 and NC images and evaluated the model performance by mean intersection over union (mIoU) against manual outlines. Only 14 cases were required to accomplish a mIoU of 0.82 for cancer segmentation in hematoxylin-stained NC cases. For PD-L1-stained slides, a model trained on PD-L1 tiles augmented by registered NC tiles achieved a mIoU of 0.79. In segmented cancer regions from whole slide images, the digital TPS achieved an accuracy of 75% against the manual TPS scores from the pathology report. Major reasons for algorithmic inaccuracies include the inclusion of immune cells in cancer outlines and poor nuclear segmentation of cancer cells. Our transparent and stepwise approach and performance metrics can be applied to any IHC assay to provide pathologists with important insights on when to apply and how to evaluate commercial automated IHC scoring systems.

BACKGROUND: Physical function is associated with cancer-related quality of life and survival. The correlation of patient-reported and objective measures of physical function has not been quantified previously in the cancer rehabilitation medicine setting. OBJECTIVE: To correlate patient-reported physical function with objective measures of physical function. The secondary aim is to correlate fatigue and social participation levels with objective measures of physical function. DESIGN: Retrospective. SETTING: Tertiary university cancer center. PARTICIPANTS: A total of 226 cancer survivors referred to an outpatient cancer rehabilitation medicine clinic. INTERVENTION: Not applicable. MAIN OUTCOME MEASURE: Correlation of Patient-Reported Outcomes Measurement Information System (PROMIS) Cancer Function Brief 3D Profile domains with objective physical function measured by the 30-second sit-to-stand and hand grip strength. RESULTS: Pearson correlation analysis revealed a moderate correlation between patient-reported physical function and the 30-second sit-to-stand test (r = 0.57; p <.001), and a weak correlation of patient-reported physical function and handgrip strength (r = 0.27; p <.001). Multivariable regression modeling controlling for age, gender, and receipt of systemic therapy demonstrated a significant association between patient-reported physical function and the 30-second sit-to-stand test (estimated confidence interval 0.76 [0.60, 0.92], p < .01), in addition to patient-reported function and handgrip strength (estimated 0.22 [0.10, 0.34], p < .01). Multiple myeloma but no other cancer type was inversely associated with lower physical function. CONCLUSIONS: Patient-reported physical function correlated moderately with the 30-second sit-to-stand test, whereas hand grip strength demonstrated a weak correlation. The 30-second sit-to-stand test is a suitable substitute for patient-reported physical function. Further work evaluating how measures relate to each other across cancer populations is needed before recommending a standardized set of outcome measures.
RESUMEN
BACKGROUND: This prospective cohort study, conducted at a high-volume esophageal cancer center from July 2019 to July 2022, aimed to investigate the link between the right gastroepiploic artery (RGEA) length and anastomotic leakage (AL) rates following minimally invasive esophagectomy (MIE). Real-world data on stomach blood supply in the Chinese population were examined. MATERIALS AND METHODS: A total of 516 cases were enrolled, categorized into two groups based on the Youden index-determined optimal cut-off value for the relative length of RGEA (length of RGEA/length of gastric conduit, 64.69%) through ROC analysis: Group SR (short RGEA) and Group LR (long RGEA). The primary observation parameter was the relationship between AL incidence and the ratio of direct blood supply from RGEA. Secondary parameters included the mean length of the right gastroepiploic artery, greater curvature, and the connection type between right and left gastroepiploic vessels. Patient data were prospectively recorded in electronic case report forms. RESULTS: The study revealed median lengths of 43.60 cm for greater curvature, 43.16 cm for the gastric conduit, and 26.75 cm for RGEA. AL, the most common postoperative complication, showed a significant difference between groups (16.88 vs. 8.84%, P =0.01). Multivariable binary logistic regression identified Group SR and LR (odds ratio: 2.651, 95% CI: 1.124-6.250, P =0.03) and Neoadjuvant therapy (odds ratio: 2.479, 95% CI: 1.374-4.473, P =0.00) as independent predictors of AL. CONCLUSIONS: The study emphasizes the crucial role of RGEA length in determining AL incidence in MIE for esophageal cancer. Preserving RGEA and fostering capillary arches between RGEA and LGEA are recommended strategies to mitigate AL risk.

BACKGROUND: The Albumin-Bilirubin (ALBI) score, widely used in predicting long-term prognosis for patients with hepatocellular carcinoma (HCC), has limitations due to serum albumin variability. This study aimed to develop and validate the Prealbumin-Bilirubin (preALBI) score as a reliable alternative. METHODS: A multicenter cohort of HCC patients who underwent hepatectomy was randomly divided into the training and validation cohorts. The preALBI score was developed using Cox regression models within the training cohort, incorporating serum prealbumin and bilirubin levels as crucial determinants. The survival predictive accuracy was evaluated and compared between the preALBI score with two other staging systems, including the ALBI score and the Child-Pugh grade. RESULTS: A total of 2409 patients were enrolled. In the training cohort, the preALBI score demonstrated superior performance in predicting long-term survival after hepatectomy. The preALBI score was associated with the best monotonicity of gradients (linear trend χ2: 72.84) and homogeneity (likelihood ratio χ2: 74.69), and the highest discriminatory ability (the areas under curves for 1-, 3-, and 5-year mortality: 0.663, 0.654, and 0.644, respectively). In addition, the preALBI was the most informative staging system in predicting survival (Akaike information criterion: 11325.65).The results remained consistent in both training and validation cohorts, indicating its reliable performance across different populations. CONCLUSION: The preALBI score, leveraging the stability of prealbumin, represents a promising tool for better patient stratification, providing more accurate prognostic predictions than the ALBI score and the Child-Pugh grade.

This study was conducted to observe the effect of Chinese herbal compound on the treatment of colon cancer using AOM/DSS-induced C57BL/6J colon cancer mice and to validate potential influence on intestinal flora of mice. A colorectal cancer (CRC) mouse model was built with a total of 50 C57BL/6J mice that were induced by administrating AOM/DSS. These experimental animals were split up into 5 groups, a control group, a model group, and low-, medium- and high-dose Chinese herbal compound groups. All mice were given Chinese herbal compound treatment, and the colon tissues of each group were harvested with the length measured and the number of colon polyps accounted. The Ki-67 expression in the colon tissues was detected via immuno-histochemistry. Relative quantification of the expression of genes and proteins was determined through qPCR and WB assays. Contents of IL-6, TNF-α, IFN-γ, and IL-10 in serum and colon tissues of mice were determined by ELISA. An additional 16S rRNA sequencing analysis was implemented for the identification of mouse intestinal flora. The results suggested that all low-, medium- or high-dose Chinese herbal compound could markedly inhibit the shortening of colon length and significant number reduction of colon polyps in the model group. The relative expression of genes and proteins (PCNA, Muc16, and MMP-9) associated with proliferation in mouse colon tissues were inhibited. In addition, compared with the model group, the contents of IL-6, TNF-α, and IFN-γ in serum and colon tissues were substantially decreased in the high-dose Chinese herbal compound group, thereby reducing the structure damage in colon tissues and the infiltration degree of inflammatory cells. Besides, the expression of TLR4/MyD88/NF-κB protein was markedly decreased. The 16S rRNA sequencing analysis demonstrated that mice in the model group had decreased intestinal flora diversity, and there were significant changes in flora abundance and amino acid metabolism between the control group and the model group. Taken together, the treatment of Chinese herbal compound against CRC in this study might be regulated by the TLR4/MyD88/NF-κB signaling pathway, and the imbalance in intestinal flora was also closely related to CRC occurrence.
RESUMEN
Multidrug-resistant (MDR) bacteria are widespread in the environment and pose a serious threat to public health. It has been shown that bacteriocins have a great potential in controlling MDR pathogens, including Staphylococcus aureus. A previously reported Lactobacillus salivarius bacteriocin XJS01 exhibited good antibacterial activity against MDR S. aureus 2612:1606BL1486 (henceforth referred to as S. aureus_26), but its molecular mechanism remains unknown. Herein, we investigated the antibacterial mechanism of XJS01 on S. aureus_26 using an approach combining transcriptomics and metabolomics. The results showed that XJS01 induced significant changes at both transcriptional and metabolic levels in S. aureus_26. In total, 231 differentially expressed genes (DEGs) and 206 differentially abundance metabolites (DAMs) were identified in S. aureus_26 treated with 1 × MIC (minimum inhibition concentration) XJS01 compared with untreated (XJS01-free) cells (control). Functional analysis revealed that these DEGs and DAMs, alone with the related pathways and biological processes, were typically involved in stress response, being primarily related to metal uptake, cell virulence, self-help mechanism, amino acid and energy metabolism, bacterial stress response (e.g., two-component system), and membrane transport (e.g., phosphotransferase system). Overall, this study uncovered the multi-target effects of bacteriocins against MDR S. aureus at the genome-wide transcriptional and metabolic levels. These findings might be useful in the development of bacteriocins for the control of MDR S. aureus and other drug-resistant bacteria.

Written clinical language embodies and reflects the clinician's mental models of disease. Prior to the COVID-19 pandemic, pneumonia was shifting away from concern for healthcare-associated pneumonia and toward recognition of heterogeneity of pathogens and host response. How these models are reflected in clinical language or whether they were impacted by the pandemic has not been studied. We aimed to assess changes in the language used to describe pneumonia following the COVID-19 pandemic.

OBJECTIVES: In a real-world trial, we previously demonstrated that Huntsman at Home, a novel oncology hospital at home program, was associated with reduced health care utilization and costs. In this study, we sought to understand the impact of Huntsman at Home in specific patient subgroups defined by sex, age, area-level median income, Charlson Comorbidity Index, and current use of systemic anticancer therapy. DESIGN: Retrospective case-control study of the Huntsman Cancer Institute. Electronic Data Warehouse of patients enrolled in Huntsman at Home between August 2018 through October 2019 vs usual-care patients. SETTING AND PARTICIPANTS: A total of 169 patients admitted to Huntsman at Home compared with 198 usual-care patients. METHODS: Five dichotomous subgroups evaluated including sex (female vs male), age (≥65 vs <65), income (≥$78,735 vs <$78,735), Charlson Comorbidity Index (≥2 vs <2), and current systemic anticancer therapy use vs no current systemic anticancer therapy. Groups were compared with patients receiving usual care. Primary outcomes included 30-day costs, hospital length of stay, unplanned hospitalizations, and emergency room visits. RESULTS: Admission to Huntsman at Home was associated with an overall reduction across all 4 health care cost and utilization outcomes. Outcomes favoring admission to Huntsman at Home achieved statistical significance (P < .05) in at least 2 of the 4 outcomes for each subgroup studied. Of the subgroups that did not achieve statistically significant benefit from Huntsman at Home admission in some outcome categories, none of these subgroups favored usual care. CONCLUSIONS AND IMPLICATIONS: Admission to Huntsman at Home decreased utilization of unplanned health care and reduced costs across a wide spectrum of patient subgroups, suggesting overall consistent benefit from the service. Hospital at home models should be considered as a means by which the quality and efficiency of care can be maximized for patients with cancer.

BACKGROUND: Lymph nodes along the left recurrent laryngeal nerve (LRLN) is thought to be highly involved in esophageal cancer. Given the unique anatomical positioning of the nerve, performing lymphadenectomy in this region requires advanced techniques within limited working space. Meanwhile, high incidence of morbidity and mortality is associated with lymphadenectomy. Although several methods have been applied to reduce the technical requirement and the incidence of postoperative complication, the optimal method remains controversial. METHODS: This study was a single-center, prospective, randomized trial to investigate the utility of lymphadenectomy along the LRLN during the minimally invasive esophagectomy in esophageal squamous cell carcinoma patients by comparing the surgical outcome, postoperative complication, survival rate, and quality of life (QoL) between the retraction method (RM) and the suspension method (SM) in patients with esophageal cancer from June 2018 to November 2020. QoL was assessed according to questionnaire: EQ-5D-5L. RESULTS: Of 94 patients were enrolled and randomized allocated to RM and SM group equally. Characteristics did not differ between groups. The duration of lymph node dissection along LRLN was significant longer in SM group ( P <0.001). No difference was observed about postoperative complications. One of in-hospital death was occurred in each group ( P >0.999). Patients in neither of groups exhibiting difference about 3-year disease-free survival rate ( P =0.180) and overall survival rate ( P =0.430). No difference was observed in postoperative QoL between groups at different time points (all, P >0.05). CONCLUSION: Both methods of lymph node dissection along the LRLN during minimally invasive esophagectomy in esophageal squamous cell carcinoma patients are technically feasible and safe. The RM appears more favorable in terms of reducing surgical duration compared to the SM.

BACKGROUND AND OBJECTIVE: According to the Barcelona Clinic Liver Cancer (BCLC) algorithm, tumor burden and liver function, but not tumor biology, are the key factors in determining tumor staging and treatment modality, and evaluating treatment prognosis. The serum α-fetoprotein (AFP) level is an important characteristic of hepatocellular carcinoma (HCC) biology, and we aimed to evaluate its prognostic value for patients undergoing liver resection of early-stage HCC. METHODS: Patients who underwent curative liver resection for early-stage HCC were identified from a multi-institutional database. Patients were divided into three groups according to preoperative AFP levels: low (< 400 ng/mL), high (400-999 ng/mL), and extremely-high (≥ 1000 ng/mL) AFP groups. Overall survival (OS) and recurrence rates were compared among these three groups. RESULTS: Among 1284 patients, 720 (56.1%), 262 (20.4%), and 302 (23.5%) patients had preoperative low, high, and extremely-high AFP levels, respectively. The cumulative 5-year OS and recurrence rates were 71.3 and 38.9% among patients in the low AFP group, 66.3 and 48.5% in the high AFP group, and 45.7 and 67.2% in the extremely-high AFP group, respectively (both p < 0.001). Multivariate Cox regression analysis identified both high and extremely-high AFP levels to be independent risk factors of OS (hazard ratio [HR] 1.275 and 1.978, 95% confidence interval [CI] 1.004-1.620 and 1.588-2.464, respectively; p = 0.047 and p < 0.001, respectively) and recurrence (HR 1.290 and 2.050, 95% CI 1.047-1.588 and 1.692-2.484, respectively; p = 0.017 and p < 0.001, respectively). CONCLUSIONS: This study demonstrated the important prognostic value of preoperative AFP levels among patients undergoing resection for early-stage HCC. Incorporating AFP to prognostic estimation of the BCLC algorithm can help guide individualized risk stratification and identify neoadjuvant/adjuvant treatment necessity.

BACKGROUND: Cancer-related fatigue (CRF) is a common and debilitating symptom experienced by patients with advanced-stage cancer, especially those undergoing antitumor therapy. This study aimed to evaluate the efficacy and safety of Renshenguben (RSGB) oral solution, a ginseng-based traditional Chinese medicine, in alleviating CRF in patients with advanced hepatocellular carcinoma (HCC) receiving antitumor treatment. METHODS: In this prospective, open-label, controlled, multicenter study, patients with advanced HCC at BCLC stage C and a brief fatigue inventory (BFI) score of ≥ 4 were enrolled. Participants were assigned to the RSGB group (RSGB, 10 mL twice daily) or the control group (with supportive care). Primary and secondary endpoints were the change in multidimensional fatigue inventory (MFI) score, and BFI and functional assessment of cancer therapy-hepatobiliary (FACT-Hep) scores at weeks 4 and 8 after enrollment. Adverse events (AEs) and toxicities were assessed. RESULTS: A total of 409 participants were enrolled, with 206 assigned to the RSGB group. At week 4, there was a trend towards improvement, but the differences were not statistically significant. At week 8, the RSGB group exhibited a significantly lower MFI score (P < 0.05) compared to the control group, indicating improved fatigue levels. Additionally, the RSGB group showed significantly greater decrease in BFI and FACT-Hep scores at week 8 (P < 0.05). Subgroup analyses among patients receiving various antitumor treatments showed similar results. Multivariate linear regression analyses revealed that the RSGB group experienced a significantly substantial decrease in MFI, BFI, and FACT-Hep scores at week 8. No serious drug-related AEs or toxicities were observed. CONCLUSIONS: RSGB oral solution effectively reduced CRF in patients with advanced HCC undergoing antitumor therapy over an eight-week period, with no discernible toxicities. These findings support the potential of RSGB oral solution as an adjunctive treatment for managing CRF in this patient population.

BACKGROUND: Hepatic pedicle clamping (HPC) is frequently utilized during hepatectomy to reduce intraoperative bleeding and diminish the need for intraoperative blood transfusion (IBT). The long-term prognostic implications of HPC following hepatectomy for hepatocellular carcinoma (HCC) remain under debate. This study aims to elucidate the association between HPC and oncologic outcomes after HCC resection, stratified by whether IBT was administered. PATIENTS AND METHODS: Prospectively collected data on patients with HCC who underwent curative resection from a multicenter database was studied. Patients were stratified into two cohorts on the basis of whether IBT was administered. The impact of HPC on long-term overall survival (OS) and recurrence-free survival (RFS) between the two cohorts was assessed by univariable and multivariable Cox regression analyses. RESULTS: Of 3362 patients, 535 received IBT. In the IBT cohort, using or not using HPC showed no significant difference in OS and RFS outcomes (5-year OS and RFS rates 27.9% vs. 24.6% and 13.8% vs. 12.0%, P = 0.810 and 0.530). However, in the non-IBT cohort of 2827 patients, the HPC subgroup demonstrated significantly decreased OS (5-year 45.9% vs. 56.5%, P < 0.001) and RFS (5-year 24.7% vs. 33.3%, P < 0.001) when compared with the subgroup without HPC. Multivariable Cox regression analysis identified HPC as an independent risk factor of OS and RFS [hazard ratios (HR) 1.16 and 1.12, P = 0.024 and 0.044, respectively] among patients who did not receive IBT. CONCLUSIONS: The impact of HPC on the oncological outcomes following hepatectomy for patients with HCC differed significantly whether IBT was administered, and HPC adversely impacted on long-term survival for patients without receiving IBT during hepatectomy.
