RESUMEN

To evaluate the efficacy, feasibility and safety of neoadjuvant therapy (NAT) for renal cell carcinoma with tumor thrombus (RCC-TT) in terms of response, perioperative and oncological outcomes, and compare the results between neoadjuvant and non-neoadjuvant groups. Overall, 29 single-arm studies and 5 cohort studies were included. Of the 204 patients undergoing NAT, 16.2% were level I, 35.3% level II, 24.0% level III and 18.6% level IV thrombus. Most of patients underwent preoperative targeted therapy, immunotherapy-based combination therapy was applied in 5.4% patients. The total reduction rate of thrombus level was 29.4%. NAT is associated with a shorter operative time, less blood loss (p<0.05 for both). Rate of complications and oncological outcomes were similar between two groups. Overall, 32.1% (34/106) ≥ grade 3 adverse events occurred in patients undergoing NAT. Neoadjuvant therapy is safe and feasible with acceptable perioperative outcomes in RCC-TT.

RESUMEN

BACKGROUND: Venous thromboembolism (VTE) is a principal cause of mortality and adverse oncologic outcomes in patients with renal tumor and inferior vena cava tumor thrombus (RT-IVCTT). However, the preoperative thrombotic risk factors in these patients remain not fully characterized. OBJECTIVES: To identify preoperative thrombotic risk factors in patients with RT-IVCTT. PATIENTS/METHODS: Two hundred fifty-seven consecutive postsurgical patients with RT-IVCTT aged 18-86 years were enrolled between January 2008 and September 2022. Clinicopathological variables were retrospectively reviewed. A multivariate logistic regression model was performed. Preoperative hemoglobin, neutrophils, and serum albumin levels were analyzed as both continuous and categorical variables. RESULTS: VTE was identified in 63 patients (24.5%). On both continuously and categorically coded variables, advanced IVC thrombus (OR 3.2, 95% CI: 1.4-7.0; OR 2.7, 95% CI: 1.2-6.1), renal sinus fat invasion (OR 3.4, 95% CI: 1.6-7.0; OR 3.7, 95% CI: 1.8-7.7), IVC wall invasion (OR 3.6, 95% CI: 1.6-7.9; OR 4.3, 95% CI: 1.9-10.0), IVC blockage status of greater than 75% (OR 5.2, 95% CI: 1.7-15.8; OR 6.1, 95% CI: 1.9-19.7), and higher neutrophils (OR 1.3, 95% CI: 1.0-1.7; OR 2.4, 95% CI: 1.1-5.4) were significantly associated with increased VTE risk in patients with RT-IVCTT. Except hemoglobin, categorically coded serum albumin (OR 0.36, 95% CI: 0.17-0.75) was validated as an independent risk factor for VTE. CONCLUSIONS: This study provided an insight of risk factors contributing to preoperative VTE in patients with RT-IVCTT, which may be beneficial for optimizing strategies to manage VTE in clinical practice.

RESUMEN

Untreated pain in critically ill patients can lead to immunosuppression and increased metabolic activity, with severe clinical consequences such as tachypnea and delirium. Continuous pain assessment is challenging due to nursing shortages and intensive care unit (ICU) workload. Mechanical ventilation equipment obscures the facial features of many patients in the ICU, making previous facial pain detection methods based on full-face images inapplicable. This paper proposes a facial Action Units (AUs) guided pain assessment network for faces under occlusion. The network consists of an AU-guided (AUG) module, a texture feature extraction (TFE) module, and a pain assessment (PA) module. The AUG module automatically detects AUs in the non-occluded areas of the face. In contrast, the TFE module detects the facial landmarks and crops prior knowledge patches, a random exploration patch, and a global feature patch. Then these patches are fed into two convolutional networks to extract texture features. Afterward, the designed AU guidances and texture features are fused in the PA module to assess the pain state. Extensive validation is conducted on a public dataset and two datasets created in this work. The proposed network architecture achieves superior performance in binary classification, four-class classification, and intensity regression tasks. In addition, we have successfully applied the network to actual data collected in the laboratory environment with excellent results.

RESUMEN

Bladder cancer (BC) invasion is a critical factor that impacts the prognosis and quality of life of patients. However, the underlying mechanisms of BC invasion is far from clear. Fibroblast growth factor 13 (FGF13), a non-secretory FGF, has been found to be ectopically expressed in various tumors and implicated in tumor development, but its potential association to BC has not been investigated. Here, we reported that the expression of FGF13A, one nucleolar isoform of FGF13, was downregulated in BC patients and negatively associated with tumor invasion. Additionally, we demonstrated that overexpression of FGF13A could inhibit the migration and invasion of BC 5637 and T24 cells. We also confirmed the localization of FGF13A in the nucleolus and its interaction with nucleoproteins NPM1 and UBP. Subsequently, we identified that the N-terminal region of FGF13A was essential for its nucleolus location and interaction with NPM1. Furthermore, we found that FGF13A inhibited the generation of nascent ribosomal RNA and suppressed the migration and invasion of BC cells through its N-terminal region. Our research establishes, for the first time, a correlation between the expression of FGF13A and the onset and progression of BC. This provides novel insights into the role of FGF13A in the development of BC.

RESUMEN

Background: Bladder cancer (BC) is the most common malignancy of the urinary tract in China, and the extent of tumor invasion negatively correlates with prognosis. The mechanism of tumor invasion in BC has been unclear until recent studies revealed the critical role of long noncoding RNAs (lncRNAs) in the proliferation and invasion of tumors. Several lncRNAs have been reported to be associated with pathogenesis in BC, but not specifically. Methods: We used a microarray to screen the candidate lncRNAs with different expressions in BC. The expression of the lncRNAs in BC tissues or cells was identified by reverse transcription polymerase chain reaction (RT-PCR) or quantitative real-time PCR (qRT-PCR), and their ectopic expressions were measured via transfection experiment. The function of the lncRNAs was investigated by flow cytometry, caspase-3 enzyme linked immunosorbent assay (ELISA), Cell Counting Kit-8 (CCK-8), wound healing, transwell and colony formation experiments in vitro and xenograft experiments in vivo. Results: We identified a novel sense lncRNA, NONHSAT070806, that was downregulated in BC tissues and cells and negatively correlated with level of tumor invasion in patients. Furthermore, overexpression of NONHSAT070806 induced apoptosis of T24 and 5637 cells, inhibited the proliferation, migration and invasion of BC cells, and attenuated the tumorigenesis of BC cells both in vitro and in vivo. Conclusions: NONHSAT070806 may act as a suppressor of BC and is a potential indicator of the invasiveness of BC.
