Six rats underwent MRI of their kidneys at baseline (24 hours prior) and at 2, 4, 6, and 8 hours post-AKI model generation. The employed MRI sequences encompassed both conventional and functional modalities, including intravoxel incoherent motion imaging (IVIM), diffusion tensor imaging (DTI), and diffusion kurtosis imaging (DTI). The analysis encompassed both DWI parameters and the histological results, seeking significant connections.
The renal cortex's fractional anisotropy (FA) value, as measured by DTI, and its apparent diffusion coefficient (ADC) both exhibited a substantial decrease at 2 hours. Subsequent to model generation, a steady elevation in mean kurtosis (MK) values was observed in the renal cortex and medulla. A negative correlation was observed between the renal histopathological score and medullary slow ADC, fast ADC, and perfusion scores, both in the renal cortex and medulla. Similarly, ADC and FA values within the renal medulla, as measured by DTI, also demonstrated a negative correlation. In contrast, MK values for both cortex and medulla exhibited a positive correlation (r=0.733, 0.812). In this context, the cortical rapid apparent diffusion coefficient, the medullary magnetization, and the fractional anisotropy.
Optimal diagnostic parameters for AKI included slow ADC readings and slower acquisition rates. From the various parameters evaluated, cortical fast ADC presented the highest diagnostic accuracy, with an AUC of 0.950.
Early acute kidney injury (AKI) is primarily indicated by the rapid analog-to-digital conversion (ADC) within the renal cortex, while the medullary micro-kinetics (MK) value could serve as a sensitive biomarker for evaluating the severity of renal damage in surgical-acute-phase (SAP) rats.
In SAP patients, multimodal parameters of renal IVIM, DTI, and DKI may prove beneficial for the early diagnosis and severity grading of renal injury.
Multimodal renal DWI parameters, including IVIM, DTI, and DKI, could possibly contribute to the noninvasive identification of early AKI and the assessment of severity in renal injury observed in SAP rats. For early AKI diagnosis, the parameters of cortical fast ADC, medullary MK, FA, and slow ADC are optimal; cortical fast ADC holds the most potent diagnostic value. Predicting the severity grade of AKI, medullary fast ADC, MK, and FA, along with cortical MK, prove useful; the renal medullary MK value shows the strongest correlation with pathological scores.
Using renal diffusion-weighted imaging (DWI) parameters like IVIM, DTI, and DKI, a non-invasive assessment of early acute kidney injury (AKI) and severity grading of renal damage in single-animal-protocol (SAP) rats may be achievable. The optimal parameters for early AKI diagnosis are cortical fast ADC, medullary MK, FA, and slow ADC, with cortical fast ADC possessing the greatest diagnostic power. Medullary fast ADC, MK, and FA, in conjunction with cortical MK, contribute to the prediction of AKI severity grades, with the renal medullary MK value exhibiting the strongest correlation with the pathological scores.
This real-world study assessed the efficacy and safety of a combined therapy consisting of transarterial chemoembolization (TACE) with camrelizumab, a monoclonal antibody targeting programmed death-1, and apatinib in patients presenting with intermediate to advanced hepatocellular carcinoma (HCC).
The retrospective study included 586 HCC patients, categorized into a combination group (n=107) receiving TACE along with camrelizumab and apatinib, and a monotherapy group (n=479) receiving TACE alone. Propensity score matching analysis served as the technique used for matching patients. Compared to monotherapy, the combination group's overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and safety outcomes were detailed.
After adjusting for confounding factors using propensity score matching (reference 12), 84 patients in the combination treatment group were matched with 147 patients in the monotherapy group. Regarding median age, both the combination and monotherapy groups showed a value of 57 years. The proportion of male patients, however, differed; 71 out of 84 (84.5%) were male in the combination group, while 127 out of 147 (86.4%) were male in the monotherapy group. In the combined treatment group, median OS, PFS, and ORR were significantly higher than those observed in the monotherapy arm. The median OS was 241 months compared to 157 months (p=0.0008), median PFS was 135 months compared to 77 months (p=0.0003), and ORR was 59.5% (50/84) compared to 37.4% (55/147) (p=0.0002). Using multivariable Cox regression, the study found that the application of combination therapy was significantly linked to better overall survival (adjusted hazard ratio [HR], 0.41; 95% confidence interval [CI], 0.26-0.64; p<0.0001) and progression-free survival (adjusted HR, 0.52; 95% CI, 0.37-0.74; p<0.0001). Joint pathology In the combined treatment arm, adverse events of grade 3 or 4 occurred in 14 patients (167% of the 84 patients treated) whereas in the monotherapy group 12 (82% of the 147 patients) patients experienced such events.
The combined treatment of TACE with camrelizumab and apatinib showed a statistically significant enhancement of overall survival, progression-free survival, and objective response rate, when contrasted with TACE alone, primarily in patients with advanced hepatocellular carcinoma.
TACE therapy, when augmented by immunotherapy and molecularly targeted treatments, displayed enhanced clinical performance in the management of largely advanced hepatocellular carcinoma (HCC) patients, yet with a more frequent occurrence of adverse effects in comparison to TACE monotherapy.
This propensity score-matched cohort study indicates superior overall survival, progression-free survival, and objective response rate with the combined use of TACE and immunotherapy/molecularly targeted therapy compared to TACE alone in treating HCC. The frequency of grade 3 or 4 adverse events was higher in the TACE plus immunotherapy and molecular-targeted therapy group (14/84, or 16.7%) than in the monotherapy group (12/147, or 8.2%). No grade 5 adverse events were detected in any of the treatment groups.
This study, employing propensity score matching, highlights the improved overall survival, progression-free survival, and response rate observed in patients with hepatocellular carcinoma (HCC) treated with a combination of transarterial chemoembolization (TACE), immunotherapy, and molecularly targeted therapy when compared to TACE alone. Adverse events of grade 3 or 4 were observed in 14 patients (16.7%) of the 84 treated with TACE, immunotherapy, and molecularly targeted therapy, compared to 12 (8.2%) of the 147 patients receiving monotherapy. Importantly, no grade 5 adverse events were recorded in any group.
In a radiomics nomogram based on gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid (Gd-EOB-DTPA) MRI, we evaluated the capacity to predict microvascular invasion (MVI) in hepatocellular carcinoma (HCC) preoperatively, and to single out suitable candidates for postoperative adjuvant transarterial chemoembolization (PA-TACE).
From three hospitals (140 in the training cohort, 65 in the standardized external validation cohort, and 55 in the non-standardized external validation cohort), a total of 260 eligible patients were retrospectively enrolled. Before each hepatectomy, the Gd-EOB-DTPA MRI image of each lesion was assessed for the extraction of radiomics features and image characteristics. The training cohort was utilized to construct a radiomics nomogram that included the radiomics signature and associated radiological predictors. The radiomics nomogram's performance, including discrimination, calibration, and clinical utility, underwent external validation. For the purpose of patient categorization, an m-score was generated, and the accuracy of its prediction of patients benefiting from PA-TACE was assessed.
The radiomics signature, incorporated into a radiomics nomogram with the criteria of max-diameter greater than 51cm, peritumoral low intensity (PTLI), incomplete capsule, and irregular morphology, showed favorable discrimination in the training, standardized external validation, and non-standardized external validation cohorts (AUC=0.982, 0.969, and 0.981 respectively). Radiomics nomogram's clinical applicability was underscored by the decision curve analysis. A log-rank test revealed that PA-TACE substantially decreased early recurrence in the high-risk patient cohort (p=0.0006), exhibiting no such effect in the low-risk group (p=0.0270).
By combining radiomics signatures and clinical radiological data within a novel radiomics nomogram, clinicians can now achieve preoperative, non-invasive prediction of MVI risk and patient benefit assessment post-PA-TACE, enabling more appropriate interventions.
Our radiomics nomogram, a potentially novel biomarker, could help identify patients who may gain from postoperative adjuvant transarterial chemoembolization, thereby enabling clinicians to implement more appropriate and precision-targeted therapies.
