RESUMO
BACKGROUNDS: To compare the efficacy and safety of transcatheter arterial chemoembolization (TACE) combined Lenvatinib plus Camrelizumab (TLC) in unresectable hepatocellular carcinoma (uHCC) with those of TACE alone . METHODS: A retrospective analysis was performed on 222 patients with uHCC who were treated between September 2013 and Jun 2023. One group received TACE + lenvatinib + camrelizumab (TLC) (n = 97) and another group received TACE alone (n = 151). Efficacy and safety were compared after propensity score matching between the TLC and TACE groups. RESULTS: After propensity matching, the TLC group had higher objective response rate (ORR) (88.6% vs. 28.6%, P < 0.001), disease control rate (DCR) (94.3%% vs. 72.9%, P < 0.001), and conversion rates before and after propensity matching were 44.1% and 41.4%, respectively, compared with the TACE group. The median progression free survival (PFS) was longer in the TLC group than in the TACE group (12.7 vs. 6.1 months, P = 0.005). The median overall survival (OS) was longer in the TLC group than in the TACE group (19.4 vs. 13.0 months, P = 0.023). Cox multivariate analysis with different modes of adjustment showed that treatment was an independent influencing factor of PFS and OS. The interaction analysis showed that cirrhosis and Child-Pugh stage an interactive role in the PFS of different treatment. Decreased AFP after treatment portends higher ORR and DCR. CONCLUSION: TACE combined Lenvatinib plus Camrelizumab regimen was safe and superior to TACE alone in improving PFS, OS, and tumor response rates for unresectable recurrent HCC patients.

BACKGROUND: This study was recruited to compare the efficacy and safety of radiotherapy (RT) and transarterial chemoembolization (TACE) as postoperative adjuvant therapy after narrow-margin hepatectomy in hepatocellular carcinoma (HCC) patients. METHODS: This single-center prospective randomized study was conducted in the Cancer Hospital, Guang Xi Medical University, Nanning. A total of 72 patients who received treatment in this hospital between August 2017 and July 2019 were included and randomly allocated to TACE group (n = 48) and RT group (n = 24). Next, overall survival (OS) and progression-free survival (PFS) rates, recurrence patterns, financial burden, and safety were evaluated. RESULTS: The difference between the RT and TACE groups was not significant in one-, three-, and five-year OS (87.5%, 79.0%, and 62.5% vs. 93.8%, 75.9%, and 63.4%, respectively, P = 0.071) and PFS rates (79.0%, 54.2%, and 22.6% vs. 75.0%, 47.9%, and 32.6%, respectively, P = 0.071). Compared to the TACE group, the RT group had significantly lower intrahepatic recurrence rate (20.8% vs. 52.1%, P = 0.011), higher extrahepatic recurrence rate (37.5% vs. 14.6%, P = 0.034), and no marginal and diffuse recurrences (0% vs. 16.7%, P < 0.05). The mean overall treatment cost was higher (¥62,550.59 ± 4397.27 vs. ¥40,732.56 ± 9210.54, P < 0.01), the hospital stay (15.1 ± 3.7 vs. 11.8 ± 4.1 days, P < 0.01) was longer, and the overall treatment stay (13.3 ± 5.3 vs. 41.29 ± 12.4 days, P < 0.01) was shorter in the TACE group than in the RT group. Besides, both groups did not exhibit significant differences in the frequency and severity of adverse events. CONCLUSION: Both adjuvant TACE and RT can better the OS and PFS of patients with HCC. However, RT has a significantly better performance than TACE in terms of improving intrahepatic recurrence rate, treatment cost and hospital stay.

OBJECTIVE: To compare the detection rates of hepatic artery digital subtraction angiography (HA-DSA) and magnetic resonance imaging (MRI) gadolinium diethylenetriaminepentaacetic acid (MRI-Gd-DTPA) and MRI gadolinium diethylenetriaminepentaacetic acid (MRI-Gd-EOB-DTPA) for small (diameter ≤2 cm) hepatocellular carcinoma (HCC) lesions. METHODS: A prospective analysis of patients admitted to the Tumor Hospital of Guangxi Medical University between January 1, 2015, and December 30, 2016, was conducted. The detection rates of the three methods were analyzed. The diameter of small HCC lesions detected using HA-DSA and MRI-Gd-EOB-DTPA were evaluated. The diagnostic value of HCC Barcelona staging for HA-DSA was analyzed. RESULTS: For 107 small lesions detected in 57 patients, the detection rates of HA-DSA and MRI-Gd-DTPA were 86.0% (92/107) and 71.0% (76/107), respectively (p < .05). Of 77 small lesions detected in 42 patients using MRI-Gd-EOB-DTPA and HA-DSA, 67 were detected using HA-DSA, all of which had a rich blood supply, and 72 were detected using MRI-Gd-EOB-DTPA. The minimum diameter of lesions detected using MRI-Gd-EOB-DTPA was approximately 0.4 cm, whereas that of lesions detected using HA-DSA was approximately 0.5 cm. After HA-DSA, a change in the Barcelona staging occurred in 33.3% (62/186) of cases but not after MRI-Gd-DTPA; HA-DSA was significantly better than MRI-Gd-DTPA for staging (p = .03). CONCLUSION: HA-DSA and MRI-Gd-EOB-DTPA have high diagnostic values for the detection of small HCC lesions, which is helpful for accurate staging of HCC and provides the most valuable information for patient treatment and prognosis.

BACKGROUND: Current sedatives have different side effects in long-term sedation. The sequential use of midazolam and dexmedetomidine for prolonged sedation may have distinct advantages. We aimed to evaluate the efficacy and safety of the sequential use of midazolam and either dexmedetomidine or propofol, and the use of midazolam alone in selected critically ill, mechanically ventilated patients. METHODS: This single-center, randomized controlled study was conducted in medical and surgical ICUs in a tertiary, academic medical center. Patients enrolled in this study were critically ill, mechanically ventilated adult patients receiving midazolam, with anticipated mechanical ventilation for ≥ 72 h. They passed the spontaneous breathing trial (SBT) safety screen, underwent a 30-min-SBT without indication for extubation and continued to require sedation. Patients were randomized into group M-D (midazolam was switched to dexmedetomidine), group M-P (midazolam was switched to propofol), and group M (sedation with midazolam alone), and sedatives were titrated to achieve the targeted sedation range (RASS - 2 to 0). RESULTS: Total 252 patients were enrolled. Patients in group M-D had an earlier recovery, faster extubation, and more percentage of time at the target sedation level than those in group M-P and group M (all P < 0.001). They also experienced less weaning time (25.0 h vs. 49.0 h; HR1.47, 95% CI 1.05 to 2.06; P = 0.025), and a lower incidence of delirium (19.5% vs. 43.8%, P = 0.002) than patients in group M. Recovery (P < 0.001), extubation (P < 0.001), and weaning time (P = 0.048) in group M-P were shorter than in group M, while the acquisition cost of sedative drug was more expensive than other groups (both P < 0.001). There was no significant difference in adverse events among these groups (all P > 0.05). CONCLUSIONS: The sequential use of midazolam and dexmedetomidine was an effective and safe sedation strategy for long-term sedation and could provide clinically relevant benefits for selected critically ill, mechanically ventilated patients.

Filter-feeding bivalves can accumulate paralytic shellfish toxins (PST) produced by toxic microalgae, which may induce oxidative stress and lipid peroxidation. Peroxisomal acyl-coenzyme A oxidases (ACOXs) are key enzymes functioning in maintaining redox and lipid homeostasis, but their roles in PST response in bivalves are less understood. Herein, a total of six and six ACOXs were identified in the Chlamys farreri and Patinopecten yessoensis genome, respectively, and the expansion of ACOX1s was observed. Gene expression analysis revealed an organ/tissue-specific expression pattern in both scallops, with all ACOXs being predominantly expressed in the two most toxic organs, digestive glands and kidneys. The regulation patterns of scallop ACOXs after exposure to different PST-producing algaes Alexandrium catenella (ACDH) and A. minutum (AM-1) were revealed. After ACDH exposure, more differentially expressed genes (DEGs) were identified in C. farreri digestive glands (three) and kidneys (five) than that in P. yessoensis (two), but the up-regulated DEGs showed similar expression patterns in both species. In C. farreri, three DEGs were found in both digestive glands and kidneys after AM-1 exposure, with two same CfACOX1s being acutely and chronically induced, respectively. Notably, these two CfACOX1s also showed different expression patterns in kidneys between ACDH (acute response) and AM-1 (chronic response) exposure. Moreover, inductive expression of CfACOXs after AM-1 exposure was observed in gills and mantles, and all DEGs in both tissues were up-regulated and their common DEGs exhibited both acute and chronic induction. These results indicate the involvement of scallop ACOXs in PST response, and their plasticity expression patterns between scallop species, among tissues, and between the exposure of different PST analogs.

Three-dimensional vertically aligned graphene (3DVAG) was prepared by a unidirectional freezing method, and its electrochemical performances were evaluated as electrode materials for zinc-ion hybrid supercapacitors (ZHSCs). The prepared 3DVAG has a vertically ordered channel structure with a diameter of about 20-30 µm and a length stretching about hundreds of microns. Compared with the random structure of reduced graphene oxide (3DrGO), the vertical structure of 3DVAG in a three-electrode system showed higher specific capacitance, faster ion diffusion, and better rate performance. The specific capacitance of 3DVAG reached 66.6 F·g-1 and the rate performance reached 92.2%. The constructed 3DVAG zinc-ion hybrid supercapacitor also showed excellent electrochemical performance. It showed good capacitance retention up to 94.6% after 3000 cycles at the current density of 2 A·g-1.
RESUMO
Mesenchymal stem cells (MSCs) can promote osteogenesis and are a promising therapy for postmenopausal osteoporosis. However, the relationship between improved intraosseous microcirculation and increased bone mass induced by MSCs in postmenopausal osteoporosis remains unclear. After the primary MSCs were characterized, they were transplanted into ovariectomized mice. MSCs transplantation enhanced the trabecular number, trabecular bone volume/total volume, and trabecular bone mineral density in ovariectomized mice. To determine the role of MSCs in vascular repair, mice were subjected to femoral artery ligation. Through laser speckle flowmetry, vascular perfusion and femoral trabecular bone and cortical bone analyses, we determined the effects of MSCs in promoting intraosseous angiogenesis and preventing osteoporosis in mice. MSCs effectively prevented postmenopausal osteoporosis development, which is associated with the involvement of MSCs in reestablishment of microcirculation within the skeleton.

PURPOSE: To explore the incidence and risk factors of intraoperatively acquired pressure injuries (IAPIs) in patients transferred to the intensive care unit (ICU) after surgery and establish a risk factor prediction model for IAPIs for guiding clinical intervention. DESIGN: A prospective, observational study was conducted. METHODS: This study was conducted in the West China Hospital of Sichuan University. A total of 648 patients who were transferred to the ICU after surgery were recruited from May 1, 2019, to October 30, 2020. Data were collected preoperatively, intraoperatively, and postoperatively (3 days after transfer to the ICU). The enrolled patients underwent well-developed preventive measures to prevent IAPIs in the operating room and ICU. A sociodemographic and clinical characteristic questionnaire, the Braden pressure injuries risk assessment scale, the activity of daily living scale, and the Nutrition Risk Screening-2002 were used. Descriptive, bivariate, and logistic regression analyses were conducted. FINDINGS: The incidence rate of IAPIs within 3 days was 18.67%. The Braden pressure injuries score, preoperative fasting blood glucose level, emergency surgery, and types of vasoactive drugs in the ICU were significant factors for increased risk. The risk factor prediction model was established using the perioperative Braden pressure injuries score (P = 0.027, odds ratio [OR] = 0.901), preoperative fasting blood glucose level (P = 0.027, OR = 1.111), emergency surgery (P < 0.01, OR = 5.054), types of vasoactive drugs in the ICU (P = 0.038, OR = 1.668), and surgery time (P = 0.021, OR = 2.434). The area under the receiver operating characteristic curve was 0.74; 95% confidence interval was 0.671 to 0.810; sensitivity was 0.635; specificity was 0.860; and the Youden index was 0.495. CONCLUSIONS: In patients transferred to the ICU after surgery, high fasting blood glucose level before surgery, emergency surgery, types of vasoactive drugs, and surgery time should be treated as predisposing factors in the prevention and control of IAPIs. However, the predictive effect of the perioperative Braden pressure injuries risk assessment scale on the risk of IAPIs needs to be further verified.

Cobalt (II, III) oxide (Co3O4) has been widely studied and applied in various fields, however, it suffers from slow mass and electron transfer during applications. Herein, crumpled Co3O4 and Co3O4/reduced graphene oxide (rGO) with tunable 2D-in-3D structures were prepared by combining spray pyrolysis with a graphene oxide (GO) template. The 2D Co3O4 nanoplates were interconnected with each other to form a 3D ball with many wrinkles, resulting in defect enrichment on the abundant boundaries of the nanosheets, which provided more active sites for catalytic reactions. In addition, the unique 2D-in-3D structure allowed fast mass transfer and structural stability. Furthermore, the assembled structure could be understood as being composed of uniformly distributed oxygen-containing functional groups pinning metal cations on the GO surface through electrostatic interaction, and the 2D structure of the GO enabled the in situ converted Co3O4 to grow along the GO surface with excellent dispersion. Taking advantage of the above, the Co3O4/rGO balls demonstrated an excellent oxygen evolution reaction performance, an overpotential of 298 mV at a current density of 10.0 mA cm-2 and a current density of 115.9 mA cm-2 at the overpotential of η = 500 mV.
RESUMO
OBJECTIVE: To explore the genotype-phenotype correlation of Cardio-facio-cutaneous syndrome (CFCS) caused by MAP2K1 gene variants. METHODS: Genomic DNA was extracted from peripheral blood sample from a child patient and his parents. Whole exome sequencing (WES) was carried out for the patient. Suspected variant was verified by Sanger sequencing. RESULTS: The patient was a 1-year-8-month old Chinese male who manifested short stature, psychomotor retardation, relative macrocephaly, distinctive facial features, and congenital heart disease. WES test revealed a heterozygous missense c.389A>G (p.Tyr130Cys) variant in the MAP2K1 gene. Sanger sequencing has confirmed the variant as de novo. According to ACMG/AMP guidelines, the variant was classified as pathogenic. CONCLUSION: Compared with previously reported CFCS cases due to MAP2K1 variants. The patient showed obvious behavioral problems, good appetite and tricuspid regurgitation, which may to be novel features for CFCS.

Protein isolate from crayfish by-products (CBPI) were hydrolyzed using Alcalase, neutrase, pancreatin and bromelain. Hydrolysis by Alcalase had more remarkable digesting efficiency on crayfish by-products protein than that by the other enzymes. Therefore, protein hydrolysate from Alcalase digestion (CBPHa) was selected to be fractionated by ultrafiltration according to molecular weight into three fractions F1 (MW <1kDa), F2 (MW 1-3kDa) and F3 (MW 3-10kDa). The amino acid determination revealed that CBPI had essential amino acid (EAA) close to that required for human protein synthesis. In vitro activity experiments showed that CBPHa and its fractions possessed considerable antioxidant activity. F1 exhibited the highest DPPH, superoxide radicals scavenging activities and Fe2+ chelating ability, whereas F2 showed the best hydroxyl radicals scavenging capacity and reducing power. In addition, all the fractions showed higher super oxide radical scavenging activity than the crude hydrolysates. Our findings suggest that CBPHa and their ultra filtration fractions have the potential for use in nutraceutical and functional food industries to maximize the use of crayfish processing by-products.

B-phycoerythrin (B-PE) was separated and purified from microalga Porphyridium cruentum using one-step chromatographic method. Phycobiliproteins in P. cruentum was extracted by osmotic shock and initially purified by ultrafiltration. Further purification was carried out with a SOURCE 15Q exchange column and analytical grade B-PE was obtained with a purity ratio (A545/A280) of 5.1 and a yield of 68.5%. It showed a double absorption peaks at 545 nm and 565 nm and a shoulder peak at 498 nm, and displayed a fluorescence emission maximum at 580 nm. The analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) showed a bulky band between 18 and 20 kDa which could be assigned to subunits α and ß and a low intensity band of 27 kDa assigned to γ subunit. Our protocol provides attractive alternative to consider for the purification procedure to obtain analytical grade B-PE at commercial level.

Objective To observe changes of serum neuron specific enolase (NSE) level in children patients with epilepsy by additional use of ilepcimide (piperine derivative). Methods Totally 107 epilepsy children patients were assigned to the test group (77 cases) and the control group (30 cases) ac- cording to random digit table. Children patients in the control group received anti-epileptic Western drugs only. Those in the test group additionally took ilepcimide, 5 mg/kg per day as initial dose, taken in two times. The dose was gradually added to those without control of epilepsy attack. Added dose within a week should not exceed 10 mg/kg per day. The therapeutic course for all was one year. Electoencephalo- gram (EEG) was performed before treatment, half a year after treatment, and one year after treatment, respectively. Serum NSE level was detected using electrochemiluminescence. Efficacy was assessed after 1-year treatment. Results The total effective rate was 65. 0% (50177) in the test group, with statistical difference as compared with that in the control group [30. 0% (9/30), P <0. 01 ]. Compared with before treatment, serum NES-level obviously decreased in the test group after 0. 5-year treatment and 1- year treatment respectively (P <0. 05, P <0. 01). Besides, serum NES level was lower after 1-year treatment than after 0. 5-year treatment (P <0. 05, P <0. 01). There was no statistical difference in serum NES level between the test group and the control group at each time point (P >0. 05). Results of EEG were obviously superior in the test group (3 with normal range EEG, 5 critically abnormal EEG, 69 abnormal EEG) to the control group (2 with normal range EEG and 75 abnormal EEG) after 1-year treatment, with statistical difference (Z= -2. 33, P <0. 05). There was no statistical difference in EEG results of the control group between before treatment (all abnormal EEG) and after 1-year treatment (3 critically abnormal EEG and 27 abnormal EEG) (Z = -1. 732, P > 0. 05). Conclusion Adding ilepcimide (piperine derivative) for epilepsy children patients could lower serum NSE level and the frequency of seizures, and improve results of EEG.

Langmuir-Blodgett (LB) assembly is a classical molecular thin-film processing technique, in which the material is spread onto water surface from a volatile, water-immiscible solvent to create floating monolayers that can be later transferred to solid substrates. LB has also been applied to prepare colloidal thin films with an unparalleled level of microstructural control and thickness, which has enabled the discovery of many exciting collective properties of nanoparticles and the construction of bulk nanostructured materials. To maximize the benefits of LB assembly, the nanoparticles should be well dispersed in both the spreading solvent and on water. This is quite challenging since colloids usually need contrasting surface properties in order to be stable in the water-hating organic solvents and on water surface. In addition, many organic and polymeric nanostructures dissolve in those organic solvents and cannot be processed directly. Using water-liking spreading solvents can avoid this dilemma. However, spreading of water-miscible solvents on water surface is fundamentally challenging due to extensive mixing, which results in significant material loss. Here we report a conceptually simple strategy and a general technique that allows nearly exclusive spreading of such solvents on water surface using electrospray. Since the volume of these aerosolized droplets is reduced by many orders of magnitude, they are readily depleted during the initial spreading step before any significant mixing could occur. The new strategy drastically reduces the burden of material processing prior to assembly and broadens the scope of LB assembly to previously hard-to-process materials. It also avoids the use of toxic volatile organic spreading solvents, improves the reproducibility, and can be readily automated, making LB assembly a more robust tool for colloidal assembly and thin-film fabrication.
RESUMO
A series of nitrogen-containing micropore-donimated materials, porous triazine-based frameworks (PTFs), are constructed through the structural evolution of a 2D microporous covalent triazine-based framework. The PTFs feature predictable and controllable nitrogen doping and pore structures, which serve as a model-like system to more deeply understand the heteroatom effect and micropore effect in ionic liquid-based supercapacitors. The experimental results reveal that the nitrogen doping can enhance the supercapacitor performance mainly through affecting the relative permittivity of the electrode materials. Although microspores' contribution is not as obvious as the doped nitrogen, the great performances of the micropore-dominated PTF suggest that micropore-dominated materials still have great potential in ionic liquid-based supercapacitors.
RESUMO
The aim of this study was to understand the relationship between IQ and glucose metabolism in brain cells in a wide variety of subjects with epilepsy. The study participants were 78 children with epilepsy and 15 healthy children for comparison. All participants were administered the Chinese Wechsler Intelligence Scale for Children (C-WISC). The verbal intelligence quotient (VIQ), performance intelligence quotient (PIQ), and full-scale intelligence quotient (FIQ) were compared between children with epilepsy and typically developing children. Seventy-eight patients underwent interictal positron emission computed tomography (PET) using 2-deoxy-2[(18)F]fluoro-d-glucose (FDG) as the tracer for evaluating brain glucose metabolism. Verbal intelligence quotient, PIQ, and FIQ based on the C-WISC were significantly lower in children with epilepsy than those in the healthy comparison group (P<0.001, P=0.001, and P<0.001, respectively). The IQ of patients with normal metabolism, unifocal abnormal hypometabolism, and multifocal abnormal hypometabolism determined by PET differed significantly. The extent of the abnormal hypometabolism was negatively correlated with the FIQ (rs=-0.549, P<0.001). In patients with lateralized hypometabolism based on PET, the VIQ/PIQ discrepancy scores (|VIQ-PIQ|≥15 points) differed significantly between the left hemisphere abnormal hypometabolism and right hemisphere abnormal hypometabolism subgroups, with negative values in the left and positive values in the right subgroups (P=0.004). In conclusion, brain metabolic abnormalities are correlated with IQ, and performing interictal PET along with C-WISC can better assess the extent of severity of cognitive impairment and VIQ/PIQ discrepancy.

INTRODUCTION: To determine whether immobilization after arthroscopic rotator cuff repair improved tendon healing compared with early passive motion. MATERIALS AND METHODS: A systematic electronic literature search was conducted to identify randomized controlled trials (RCTs) comparing early passive motion with immobilization after arthroscopic rotator cuff repair. The primary outcome assessed was tendon healing in the repaired cuff. Secondary outcome measures were range of motion (ROM) and American Shoulder and Elbow Surgeons (ASES) shoulder scale, Simple Shoulder Test (SST), Constant, and visual analog scale (VAS) for pain scores. Pooled analyses were performed using a random effects model to obtain summary estimates of treatment effect with 95% confidence intervals. Heterogeneity among included studies was quantified. RESULTS: Three RCTs examining 265 patients were included. Meta-analysis revealed no significant difference in tendon healing in the repaired cuff between the early-motion and immobilization groups. A significant difference in external rotation at 6 months postoperatively favored early motion over immobilization, but no significant difference was observed at 1 year postoperatively. In one study, Constant scores were slightly higher in the early-motion group than in the immobilization group. Two studies found no significant difference in ASES, SST, or VAS score between groups. CONCLUSION: We found no evidence that immobilization after arthroscopic rotator cuff repair was superior to early-motion rehabilitation in terms of tendon healing or clinical outcome. Patients in the early-motion group may recover ROM more rapidly. LEVEL OF EVIDENCE: Level II; systematic review of levels I and II studies.

Photocatalysis represents a sustainable strategy for addressing energy shortages and global warming. The main challenges in the photocatalytic process include limited light absorption, rapid recombination of photo-induced carriers, and poor surface catalytic activity for reactant molecules. Defect engineering in photocatalysts has been proven to be an efficient approach for improving solar-to-chemical energy conversion. Sulfur vacancies can adjust the electron structure, act as electron reservoirs, and provide abundant adsorption and activate sites, leading to enhanced photocatalytic activity. In this work, we aim to elucidate the role of sulfur vacancies in photocatalytic reactions and provide valuable insights for engineering high-efficiency photocatalysts with abundant sulfur vacancies in the future. First, we delve into the fundamental understanding of photocatalysis. Subsequently, various strategies for fabricating sulfur vacancies in photocatalysts are summarized, along with the corresponding characterization techniques. More importantly, the enhanced photocatalytic mechanism, focusing on three key factors, including electron structure, charge transfer, and the surface catalytic reaction, is discussed in detail. Finally, the future opportunities and challenges in sulfur vacancy engineering for photocatalysis are identified.
RESUMO
BACKGROUND: Conversion therapy for initially unresectable hepatocellular carcinoma (iuHCC) using lenvatinib combined with transcatheter arterial chemoembolization (TACE) plus a PD-1 inhibitor (LTP) has achieved promising results. However, further comparative research is necessary to evaluate the effectiveness and safety of conversion surgery (CS) for iuHCC. METHODS: Data for 32 consecutive patients with iuHCC receiving CS and 419 consecutive patients with resectable HCC receiving initial surgery (IS) between November 2019 and September 2022 were collected retrospectively. After propensity score matching (PSM), 65 patients were selected. RESULTS: Before matching, the CS group had longer EFS (not reached vs. 12.9 months, P < 0.001) and similar OS (not reached vs. not reached, P = 0.510) compared with the IS group. Similar results for EFS (P = 0.001) and OS (P = 0.190) were obtained after matching. The multivariable Cox model (HR = 0.231, 95% CI: 0.105-0.504; P < 0.001) and subgroup analyses confirmed that CS could improve EFS. The CS group had significantly lower incidence of microvascular invasion (MVI) than the IS group (3.1% vs. 50.4%, P < 0.001). Moreover, the two groups had similar safety profiles. CONCLUSIONS: CS is effective and safe for patients with iuHCC receiving LTP. LTP has the potential to reduce risk factors for postoperative recurrence, especially MVI, which may influence surgical decision-making.

Background: The prognosis of initially unresectable hepatocellular carcinoma (iuHCC) has been improved by TACE with TKIs and PD-1 inhibitors (TTP). However, the role of timing of tumor progression and and early salvage surgery during TTP therapy remains unclear. Patients and Methods: The data of 151 patients who received TTP for iuHCC consecutively between November 2019 and December 2022 were retrospectively analyzed. The X-Tile software was used to determine the optimal threshold of progression timing to differentiate the post-progression survival (PPS) for patients with tumor progression, ultimately yielding 9 months as the optimal cut-off time. Early tumor progression was defined as patients with tumor recurrence (surgical patients) or progressive disease by mRECIST (nonsurgical patients) within 9 months of initial treatment. Accordingly, early salvage surgery was defined as salvage surgery performed within 9 months of the initial treatment. Results: Out of all the patients, 55 (36.4%) patients showed early tumor progression, 33 (34.4%) showed late tumor progression, and 63 (41.7%) showed non-progression. Patients who experienced early tumor progression had a median PPS of 5.2 months, while those with late tumor progression had a median PPS of 16.8 months (P < 0.001). Multivariable analysis revealed a robust independent correlation between early tumor progression and PPS (HR = 3.279, 95% CI: 1.591-6.756; P = 0.001). Patients who received early salvage surgery showed a considerably lower early tumor progression rate when compared with patients who did not receive early surgery (12.5% vs 42.9%, P = 0.002). The multivariable analysis revealed that early salvage surgery was an independent factor influencing early tumor progression (OR = 0.246; 95% CI: 0.078-0.773; P = 0.016). Conclusion: Early tumor progression is associated with worse PPS in patients with iuHCC receiving TTP therapy. Early salvage surgery can further improve patient outcomes by lowering the incidence of early progression.
