BACKGROUND: Atezolizumab plus bevacizumab (Atez/Bev) is the first-line treatment for unresectable hepatocellular carcinoma (HCC). This study investigated the association of adverse events (AEs) with clinical outcomes by treatment relation, organ systems, and severity. METHODS: This exploratory post hoc analysis included 435 HCC patients treated with Atez/Bev, 136 patients with sorafenib, and 58 patients with atezolizumab monotherapy from the IMbrave150 (NCT03434379) and GO30140 (NCT02715531) trials. Kaplan-Meier analysis was applied to estimate overall survival (OS) in patients treated with Atez/Bev for ≥ 3 months. RESULTS: Landmark analysis at 3 months restricted the OS analysis to 332 patients who completed ≥ 3 months of Atez/Bev. Among these patients, treatment-related renal/urinary, mild vascular, and skin/subcutaneous AEs were associated with improved OS compared with patients without the corresponding AE (mOS: not reached vs. 20.2 months, p < 0.001; not reached vs. 20.2 months, p < 0.001; and not reached vs. 22.8 months, p = 0.014, respectively). Experiencing one (HR = 0.56, 95% CI: 0.38, 0.81) or ≥ 2 types (HR = 0.20, 95% CI: 0.11, 0.37) of positively associated AEs demonstrated progressively improved OS. However, metabolism/nutrition, hepatobiliary, and grade 3 + gastrointestinal AEs were associated with poorer OS, with HRs at 1.58 (95% CI: 1.10, 2.26), 1.67 (95% CI: 1.08, 2.69) and 2.09 (95% CI: 1.28, 3.41), respectively. CONCLUSIONS: Atez/Bev-related renal/urinary, skin/subcutaneous, and mild vascular AEs were associated with favorable survival outcomes in HCC, whereas metabolism/nutrition, hepatobiliary, and severe gastrointestinal AEs were associated with poorer outcomes. These findings may help improve the interpretation of AEs during Atez/Bev treatment and inform individualized toxicity management.

BACKGROUND: The management of pulmonary metastases of soft tissue and bone sarcomas is challenging due to their resistance to chemotherapy and radiotherapy. This study aimed to evaluate local tumor progression, overall survival (OS), and procedural safety after percutaneous cryoablation for pulmonary metastases of soft tissue and bone sarcomas. METHODS: This retrospective cohort study included 28 patients who underwent percutaneous cryoablation for 84 metastatic lung tumors of soft tissue and bone sarcomas during 53 sessions between July 2002 and December 2016. Percutaneous cryoablation was performed under local anesthesia using the CRYOcare system and computed tomography fluoroscopy. Procedural complications within 30 days were assessed using prospectively recorded clinical data and retrospectively graded according to the Common Terminology Criteria for Adverse Events version 5.0. The time to local progression of the treated tumors and overall survival were estimated using the Kaplan-Meier method. RESULTS: All cryoablation procedures were performed under local anesthesia. The median tumor diameter was 1.1 cm (range: 0.4-6.5 cm). Twelve tumors (14.3%) showed local tumor progression after initial cryoablation during the median follow-up duration of 16 months (range: 0-216 months). The primary efficacy rates were 88.8%, 79.1%, and 79.1% at 1, 3, and 5 years, respectively. After repeat cryoablation for four tumors with local progression, the assisted efficacy rates were 95.6%, 82.8%, and 77.9% at 1, 3, and 5 years, respectively. Three tumors in two patients had no local progression for more than 10 years. A tumor diameter of ≤ 2 cm was significantly associated with improved primary and assisted efficacy rates (P = 0.024 and P = 0.015, respectively). The median OS was 34 months (range, 2-155 months), and the OS rates were 75.0%, 52.8%, and 28.8% at 1, 3, and 5 years, respectively. Adverse events occurred in 31 sessions (58.5%); all were grade 1 or 2, and no grade ≥ 3 adverse events or 30-day mortality were observed. CONCLUSIONS: In this selected single-institution cohort of nonsurgical candidates with pulmonary metastases of soft tissue and bone sarcomas, percutaneous cryoablation was feasible and was associated with local tumor control and an acceptable safety profile.

BACKGROUND: Cancer patients often face catastrophic health expenditures (CHE), leading to significant financial burdens for households. When cancer treatment depends mainly on out-of-pocket payments, the risk of incurring CHE increases; thus, this study assessed the incidence and key factors contributing to CHE among cancer patients. METHODS: A cross-sectional study was conducted at Wolaita Sodo University Comprehensive Specialized Hospital, including 294 cancer patients selected systematically. Data were analyzed using SPSS version 27, with bivariable and multivariable logistic regression models used to assess associations between CHE and independent variables. RESULTS: Among cancer patients, the incidence of catastrophic health expenditure (CHE) at a 40% threshold was 83.7% (95% CI: 78.9-87.4). Medication cost constituted the largest treatment expense, accounting for 66.7% of total costs. Multivariable analysis identified three independent factors significantly associated with CHE: lack of formal education (AOR = 3.6; 95% CI: 1.1-12.0), absence of health insurance (AOR = 3.2; 95% CI: 1.5-7.0), and cancer diagnosis in private facilities (AOR = 4.2; 95% CI: 3.5-13.7). CONCLUSION: The incidence of catastrophic health expenditure (CHE) was higher than reported in published studies. Key contributing factors included lack of insurance, educational status, and diagnosis at private healthcare facilities, all of which exacerbated financial hardship. Expanding community-based health insurance (CBHI) is essential, especially for low-income households. Furthermore, hospitals should enhance access to cancer diagnostic services to help alleviate the financial burden of diagnosis.

BACKGROUND: To evaluate the single-session agreement between treatment recommendations generated by ChatGPT and Gemini and real-world decisions made by a thoracic oncology multidisciplinary tumor board (MDTB). METHODS: This retrospective observational study included 102 thoracic oncology cases discussed at a university hospital MDTB between June and December 2025. Cases were categorized as primary lung cancer, pulmonary mass without pathological diagnosis, esophageal cancer, or pulmonary metastasis. Standardized anonymized case summaries, including clinical, radiological, pathological, and laboratory data, were presented to ChatGPT and Gemini. Each model was asked to provide a single tumor board-like management recommendation. Each case was submitted once to each model in a separate new chat session, and the initial output was used for analysis. Recommendations were classified into predefined categories and compared with final MDTB decisions. Agreement was assessed using percentage agreement and Cohen's kappa coefficient. RESULTS: In this single-session evaluation, overall agreement with MDTB decisions was 52.0% for ChatGPT and 56.9% for Gemini. Both models showed moderate agreement, with slightly higher agreement for Gemini than ChatGPT (κ = 0.487 vs. κ = 0.432; p < 0.001). Agreement was higher in standardized scenarios, such as primary lung cancer and esophageal cancer, but lower in pulmonary masses without pathological diagnosis and pulmonary metastases. No significant difference was found between the models in overall concordance with MDTB decisions (p = 0.359). CONCLUSION: The initial outputs of ChatGPT and Gemini showed moderate agreement with MDTB decisions in this single-session evaluation. LLMs may support guideline-based thoracic oncology decision-making but remain limited in complex, patient-specific scenarios and should not replace multidisciplinary clinical judgment. These findings should be interpreted as concordance with real-world MDTB decisions rather than evidence of stable model-level performance or clinical accuracy.

BACKGROUND: Pleomorphic adenoma is a benign salivary gland tumor that has a potentiality to recurrence and malignant transformation as well. The genetic alteration of this tumor is not completely studied yet. Investigating the growth factor receptors and tumor microenvironment may yield answers to the nature of this tumor. METHODS: Thirty-six formalin-fixed, paraffin-embedded pleomorphic adenoma specimens were collected from Al-Mouassat University Hospital. EGFR, HER-2 and BCL-2 antibodies have been used in immunohistochemistry stains to investigate the most probable affected pathway in this progress of this tumor. RESULTS: Immunohistochemical analysis revealed total negativity for HER2 expression. While, EGFR and BCL-2 expression was positive in diffuse patchy pattern. The positivity was membranous and/or cytoplasmic predominantly within the tumor cell population. Statistical analysis revealed no significant association between EGFR/BCL-2 expression and patient gender (p = 0.848) or tumor site (p = 1.000). The absence of HER2 expression was consistent across all cases, regardless of clinicopathological parameters. The expression of EGFR and BCL2 did not show a statistically significant correlation with demographic variables, suggesting a tumor-intrinsic expression pattern rather than dependence on clinical factors. CONCLUSION: On this study, pleomorphic adenoma demonstrated a distinct immune-profile with positivity of EGFR and BCL-2 and negative expression of HER-2. These findings suggest HER-2 unlikely contribute to tumor behavior, meanwhile the positivity of EGFR and BCL-2 may be related to the tumor survival rather than malignant transformation. Moreover, these markers do not same to consider as reliable predictors of malignant transformation in pleomorphic adenoma.

BACKGROUND: Gastric cancer (GC) is one of the most common malignancies worldwide. WD repeat and HMG-box DNA-binding protein 1 (WDHD1) has been identified as an oncogenic factor involved in the progression of hepatocellular carcinoma, lung adenocarcinoma, nasopharyngeal carcinoma, and several other cancers. However, its role in GC remains insufficiently explored in the existing literature. METHODS: In this study, TCGA, GTEx, and GEO datasets were used to evaluate differences in WDHD1 expression between GC tissues and normal gastric tissues, and to analyze its associations with patient prognosis and clinicopathological characteristics. The CCLE database was used to assess WDHD1 expression levels in GC cell lines. The GDSC and CTRP pharmacogenomic databases were used to investigate the potential relationship between WDHD1 expression and sensitivity to antitumor agents. In addition, the TISCH2 single-cell database was used to analyze the distribution of WDHD1 expression across different cell populations in the GC tumor microenvironment and to preliminarily explore its association with the immune microenvironment. Subsequently, EdU, CCK-8, and colony formation assays were performed to evaluate the effect of WDHD1 on the proliferative capacity of GC cells, and a nude mouse xenograft tumor model was used to validate the regulatory role of WDHD1 in tumor growth in vivo. To further explore the potential underlying mechanisms, comparative proteomic analysis and cell-cycle flow cytometry were performed in WDHD1 knockdown cells and control cells, thereby preliminarily revealing the possible molecular mechanisms by which WDHD1 contributes to GC progression. RESULTS: WDHD1 was significantly overexpressed in GC, and its high expression was associated with poor prognosis and showed favorable diagnostic value. Functional enrichment analysis indicated that high WDHD1 expression was mainly associated with enrichment of pathways related to the cell cycle, DNA replication, and cell proliferation. In GC, WDHD1 downregulation exerted tumor-suppressive effects, inhibited DNA synthesis, and induced cell-cycle redistribution. CONCLUSION: WDHD1, as a key factor regulating DNA replication and cell cycle progression during GC progression, may serve as a potential molecular target for diagnosis, prognostic assessment, and therapeutic intervention in GC.

Acute lymphoblastic leukaemia (ALL) is characterized by uncontrolled proliferation of lymphoid progenitor cells. Advances in genomic and epigenomic profiling have enabled the identification of over 40 molecular subtypes defined by distinct genetic drivers, transcriptional programmes and regulatory alterations. These insights have refined the classification, particularly of B cell precursor ALL (B-ALL) and are increasingly informing risk stratification, therapeutic decision-making and disease monitoring. By contrast, the classification of T cell ALL (T-ALL) has historically relied on immunophenotypic criteria, but recent large-scale genomic studies have uncovered biologically defined subtypes driven by diverse coding and noncoding alterations. Many genomic lesions represent clinically actionable vulnerabilities, including kinase-activating alterations that have enabled the use of targeted therapies. However, treatment resistance remains a major challenge, arising through clonal evolution, acquisition of secondary mutations and adaptive transcriptional and epigenetic reprogramming. In this Review, we highlight recent advances in understanding of the biological basis of ALL, with a focus on recently identified genetic alterations, gene expression patterns, alterations in three-dimensional genome architecture and epigenetic regulation that drive ALL initiation, progression and therapeutic response. Furthermore, we discuss how genetic heterogeneity contributes to clinical variability and how integrating molecular and biological insights can improve risk stratification and therapeutic outcomes.

BACKGROUND: Survivors of Ewing sarcoma (EWS) are at significant long-term risk of treatment- and disease-related complications. The purpose of this study was to characterize long-term outcomes in EWS survivors according to treatment regimen. METHODS: Five-year survivors of EWS diagnosed between 1970 and 1999 from the Childhood Cancer Survivor Study were included. Late mortality (>5 years from diagnosis), subsequent malignant neoplasms (SMNs), and severe to fatal chronic health conditions (CHCs) by chemotherapy regimen were compared. Patients were compared to siblings via cumulative incidence and proportional hazards models. Standardized mortality ratios (SMRs) compared late mortality between survivors and the general population. RESULTS: Survivors (N = 739) had higher all-cause (SMR, 6.16; 95% CI, 5.36-7.05), SMN-related (SMR, 9.24; 95% CI, 6.92-12.08), cardiac-related (SMR, 4.53; 95% CI, 2.81-6.93), and noncardiopulmonary health-related (SMR, 2.04; 95% CI, 1.25-3.15) mortality compared with the general population. Compared with siblings (N = 5040), survivors had an increased risk of developing CHCs (any: hazard ratio [HR], 5.49; 95% CI, 4.58-6.59; cardiovascular: HR, 4.59; 95% CI, 3.67-5.74; neurological: HR, 2.82; 95% CI, 1.72-4.63; respiratory: HR, 5.37; 95% CI, 2.76-10.5; renal: HR, 4.61; 95% CI, 2.26-9.40). Between chemotherapy groups within EWS, there were no statistically significant differences in all-cause, SMN-caused, or health-related late mortality and the risk of developing SMNs or CHCs (any, cardiovascular, neurological, or respiratory), except that the vincristine, doxorubicin, and cyclophosphamide (VDC) plus ifosfamide and etoposide (IE) group had a higher risk of renal complications (HR, 2.55; 95% CI, 1.07-11.7; 30-year incidence was 0.56% for VDC and 3.2% for VDC/IE). CONCLUSIONS: No differences in late mortality, SMNs, and most CHCs were observed between patients who received VDC versus VDC/IE. Aging EWS survivors' elevated risk of morbidity and mortality underscores the need for lifelong survivorship care and therapies that reduce the risk for late effects.

BACKGROUND: The programmed cell death-1 (PDCD1) gene plays a critical role in immune regulation and tumor immune evasion, making it a key target in cancer immunotherapy. Genetic variants in PDCD1, including rs2227981, rs2227982, rs7421861, and rs11568821, may influence susceptibility to female-specific cancers. This systematic review and meta-analysis aimed to evaluate the association of these variants with the risk of breast, cervical, ovarian, and endometrial cancers across ethnic populations. METHODS: A systematic literature search was conducted in PubMed, Scopus, Web of Science, and Google Scholar for studies published up to January 2025. Eligible studies were case-control in design and reported genotypic or allelic frequencies. Risk of bias was assessed using the Newcastle-Ottawa Scale. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated under dominant, recessive, and allelic genetic models. Heterogeneity was evaluated using the I² statistic. Publication bias was assessed using funnel plots, Egger's test, and Begg's test. Sensitivity analyses were performed to evaluate the robustness of the results. RESULTS: Eleven case-control studies were included, comprising 3534 breast cancer, 1468 cervical cancer, 1160 ovarian cancer, and 873 endometrial cancer cases, each with corresponding controls. The rs2227981 C allele and rs2227982 T allele were significantly associated with increased risk of female-specific cancers (p < 0.0001). Similarly, rs7421861 and rs11568821 showed significant associations across multiple genetic models. Heterogeneity ranged from low to high (I² = 19.5%-84%). No significant publication bias was detected (Egger's test p = 0.586; Begg's test p = 0.548). However, variability between studies and limited sample sizes should be considered when interpreting the findings. CONCLUSIONS: PDCD1 gene polymorphisms are associated with susceptibility to female-specific cancers, underscoring the importance of genetic variability in immune regulation and oncogenesis. Further large-scale and functional studies are needed to validate these findings and to explore gene-environment interactions.

BACKGROUND: While concurrent chemoradiotherapy (CCRT) is the standard first-line treatment, radical surgery (RS) is frequently preferred in China, despite unclear comparative efficacy. The role of minimally invasive surgery also remains controversial and requires further validation. These persistent uncertainties underscore the need to advance research into LACC treatment strategies. METHODS: We conducted a multicenter prospective cohort study at three tertiary teaching hospitals in Shanghai, including 246 patients with specific locally advanced cervical cancer (LACC; FIGO 2018 stages IB3, IIA2, or locally resectable IIICr). We compared overall survival (OS), progression-free survival (PFS), adverse events (AEs), two-year quality-adjusted life years (QALYs), and treatment costs between RS (n = 198) and definitive CCRT (n = 48). We also compared tumor-free laparoscopic RS (n = 119) with open RS (n = 79) within the RS cohort. Propensity score matching (PSM) was applied to reduce potential confounding. Subgroup and sensitivity analyses were performed to assess the robustness of the results. RESULTS: After PSM, there were no significant differences in OS or PFS between the RS and definitive CCRT groups (two-year OS: 92% [86-97%] vs. 91% [82-100%]; two-year PFS: 79% [72-87%] vs. 78% [66-91%]), nor between the tumor-free laparoscopic and open RS groups (two-year OS: 97% [93-100%] vs. 91% [84-98%]; two-year PFS: 82% [74-92%] vs. 78% [69-89%]). Subgroup and sensitivity analyses yielded consistent findings. Two-year QALYs were comparable between the RS and definitive CCRT groups (23.55 [22.54, 24.00] vs. 23.53 [22.60, 23.80] months; W = 3148, p = 0.074), but significantly higher in the tumor-free laparoscopic RS group than in the open RS group (24.00 [23.52, 24.00] vs. 23.52 [21.77, 24.00] months; W = 3060, p = 0.003). The median total treatment cost was significantly higher in the RS group than in the definitive CCRT group (96,879 [91,400-104,815] CNY vs. 83,555 [73,790-95,554] CNY; W = 347.000, p = 0.018). CONCLUSIONS: RS and definitive CCRT provided comparable short-term survival outcomes and two-year QALYs in specific LACC patients, although the RS group tended to be associated with higher treatment costs. Within the surgical cohort, tumor-free laparoscopic RS achieved similar survival outcomes to open RS but offered better two-year QoL benefits, supporting its role as a potential surgical option under strict oncologic principles.

BACKGROUND: CLL patients have immune deficiencies and are at high risk of SARS-CoV-2 infection. Limited research exists on risk factors and survival outcomes of SARS-CoV-2 infection in Asian CLL patients during the COVID-19 pandemic. Therefore, this study aims to explore the relationship between SARS-CoV-2 infection and survival in this population. METHODS: A retrospective analysis was conducted on 119 CLL patients treated at a large tertiary comprehensive hospital in western China from January 2020 to May 2023, coinciding with a surge in the epidemic in the city. RESULTS: (1) During the epidemic, the treatment group had a higher proportion of males, second-line and initial treatment, 11q- chromosome, LDH level, and lower erythrocyte count (P < 0.05). Patients in this group had longer median duration of malaise, more headaches and coughs, longer cough and sputum duration, higher rates of hyposmia, and more patients received antiviral treatment for COVID-19 and suffered weight loss. The treatment group had more CLL patients affected by SARS-CoV-2, and more patients developed secondary COVID-19 infection, and had lower RBC count and hemoglobin levels (P < 0.05). (2) Compared to the non-BTKi treatment group, more patients in BTKi treatment received treatment lasting ≥ 1 month, more had abnormal karyotyping, high-risk cytogenetics, less recent cytotoxic drug and rituximab exposure, lower lymphocyte count, elevated creatinine level, and lower glomerular filtration rate (P < 0.05). (3) Firth's penalised-likelihood logistic regression revealed that male sex increased hospitalization risk, while normal karyotyping decreased this risk. Male sex and recent rituximab exposure (within 6 months) were SARS-CoV-2 infection risk factors. Both frontline and second-or-more line therapies were associated with higher SARS-CoV-2 mortality risk compared to untreated patients (all P < 0.05). CONCLUSION: Male sex and recent exposure to rituximab within the past six months are risk factors for SARS-CoV-2 infection in CLL patients. Both frontline and second-or-more line therapies are risk factors for mortality (compared to untreated patients). Treatment with BTK inhibitors does not increase the risk of SARS-CoV-2 infection or mortality.

BACKGROUND: Single-chain antibody-based CAR-T cells targeting BAFF-R have demonstrated antitumor effects against human B-cell malignancies and can overcome CD19 antigen loss. However, CARs built on antigen-specific single-chain antibody variable fragments may have limitations, e.g., large CAR binding domain size. To improve the function of BAFF-R CAR-T cells, we designed CARs with only a fully human heavy-chain variable domain. METHODS: A fully human antibody phage display library was used to select anti- BAFF- R clones using protein/cell alternate panning. The screened clones were grafted into a second-generation CAR to generate CAR-T cells. CD107a degranulation, luciferase-based cytolysis, repeat antigen stimulation, activation markers, and exhaustion markers were used to detect the function of CAR-T cells in vitro. Xenografts were established in NPG mice following intravenous injection of Jeko-1 cells. Tumor burden and survival of mice were recorded weekly. RESULTS: Three single-domain heavy chain antibodies, namely Clone #5, Clone #77, and Clone #80, were selected for further evaluation. CAR-T cells constructed with these three candidate clones demonstrated specific target cell activation and effective cytotoxicity in vitro. Clone #5 and Clone #77 CAR-T cells exhibited superior cytotoxic capacity and expansion ability. No significant difference was observed in the expression levels of exhaustion markers on the surface of the three CAR-T cell types. In vivo studies revealed that Clone #5 CAR-T cells displayed enhanced antitumor efficacy compared to other groups, resulting in prolonged survival. CONCLUSION: We developed a novel BAFF-R CAR-T cell product structured on a fully human single-domain antibody. This product demonstrated promising preclinical activity and may provide a potential alternative treatment for patients with B-cell malignancies.

BACKGROUND: Head and neck squamous cell carcinoma (HNSCC) exhibits marked heterogeneity driven by both tumor-intrinsic programs and immune context. However, the relationship between epithelial proliferation and immune activity remains incompletely defined. METHODS: We combined bulk transcriptomic analyses of HNSCC cohorts (GSE83519 and TCGA-HNSC) with single-cell RNA sequencing data derived from OSCC (GSE172577) to identify gene programs associated with tumor progression. Co-expression network analysis was used to identify tumor-related modules, and candidate genes were evaluated by survival analysis and experimental validation. Single-cell analysis of an OSCC cohort and CopyKAT-based epithelial cell identification were performed to define cell-type-specific expression patterns. RESULTS: EOMES and SPRYD3 were identified as candidate prognostic markers associated with distinct biological programs. Single-cell analysis showed that SPRYD3 expression was enriched in aneuploid epithelial cells, whereas EOMES expression was restricted to cytotoxic lymphocyte populations. Tumor epithelial cells with high SPRYD3 expression exhibited activation of cell cycle and DNA replication pathways, while immune-related signaling was reduced. In contrast, EOMES expression was associated with interferon response and T-cell effector programs. Experimental validation supported increased SPRYD3 expression, whereas EOMES exhibited a tendency toward lower expression in OSCC tissues. CONCLUSIONS: SPRYD3 and EOMES represent distinct transcriptional programs associated with epithelial proliferation and immune activity in HNSCC. These findings provide a framework for understanding tumor-immune interactions and highlight the potential prognostic and biological relevance of EOMES and SPRYD3 in HNSCC.

BACKGROUND: Esophagectomy (OE) remains a complex procedure with a considerable risk of severe postoperative complications. There is conflicting evidence if major postoperative complications impair long-term oncological survival. This retrospective study was designed to retest the hypothesis that complications after OE impact on long-term survival in a large and highly standardized cohort of esophageal cancer patients. MATERIALS AND METHODS: 733 patients who underwent Ivor Lewis esophagectomy (IL-OE) for cancer from 2016 to 2021 at our tertiary center were analysed from a prospectively maintained database. Postoperative complications were correlated to overall survival. RESULTS: Neither occurrence of major complications ≥ Clavien-Dindo (CD) IIIB (Median OS not reached in both groups, p = 0.45, HR 1.12) nor AL (Median OS not reached for no AL vs. 50 months for AL, p = 0.49, HR 0.96) nor pulmonary complications (Median OS not reached in both groups, p = 0.61, HR 0.76) had an impact on overall survival. However, the necessity for postoperative readmission to ICU (reaICU) had a significant impact on overall survival (Median OS not reached for no reaICU vs. 40 months for reaICU, p = 0.037, HR 1.54). Mean follow up was 27 months. CONCLUSION: Among all variables, only ICU readmission significantly affected overall survival. Postoperative complications and in particular anastomotic leakage after IL-OE, per se, may have a less significant impact on overall survival than previously anticipated. This might be due to a highly sufficient management of complications that progressively avoids requirement of severe septic complications and intensive care treatment.

BACKGROUND: Integrin alpha X (ITGAX, CD11c) functions as a leukocyte adhesion molecule vital for immune cell activation, antigen presentation, and inflammatory responses. However, the expression profile, clinical relevance, immunoregulatory functions, and underlying mechanisms of ITGAX in clear cell renal cell carcinoma (ccRCC) remain incompletely elucidated. METHODS: ITGAX expression and its association with clinicopathological characteristics were examined using The Cancer Genome Atlas (TCGA)-kidney renal clear cell carcinoma (KIRC) dataset. Survival outcomes were analyzed using Kaplan-Meier and Cox regression methodologies. However, diagnostic efficacy was assessed via receiver operating characteristic (ROC) curve analysis. Immune cell infiltration, tumor purity, and immune checkpoint gene expression were evaluated using various computational algorithms. To elucidate the molecular features associated with ITGAX, functional enrichment and protein-protein interaction analyses were conducted. A KIRC single-cell RNA sequencing dataset was used to ascertain the cellular localization of ITGAX within the tumor microenvironment. In vitro validation involved the use of the ccRCC cell lines 786-O and Caki-1, alongside the normal renal epithelial cell line HK-2. ITGAX knockdown, functional assays, Western blotting, and AKT reactivation with SC79 were used to study cell phenotypes and the AKT/mTOR signaling pathway. RESULTS: ITGAX expression was markedly upregulated in TCGA-KIRC tissues and positively correlated with adverse clinicopathological characteristics, poorer overall survival, and favorable diagnostic efficacy, as evidenced by ROC curve analysis. Various computational algorithms indicated a strong association between ITGAX expression and immune cell infiltration, reduced tumor purity, elevated immune scores, and increased immune checkpoint gene expression. Functional enrichment analysis revealed that genes associated with ITGAX were predominantly involved in immune-related and microenvironment-associated pathways. Single-cell analysis demonstrated that ITGAX was predominantly enriched in myeloid cell populations, particularly monocytes/macrophages and dendritic cells, within the KIRC tumor microenvironment. In vitro experiments confirmed the relative elevation of ITGAX in ccRCC cell lines compared to HK-2 cells and revealed that ITGAX knockdown led to reduced cell proliferation, migration, invasion, and clonogenicity. ITGAX silencing was also associated with decreased AKT/mTOR phosphorylation, whereas AKT reactivation partially mitigated these phenotypic changes. CONCLUSIONS: This study suggests that ITGAX is associated with unfavorable clinical characteristics, a myeloid-enriched immune contexture, and AKT/mTOR-associated malignant phenotypes in ccRCC. These results suggest that ITGAX is a potential immune-related biomarker of ccRCC; however, additional clinical, spatial, and in vivo validation is necessary.

OBJECTIVE: To systematically evaluate the incidence of hypokalemia associated with novel androgen receptor axis-targeted therapies (ARATs)-specifically abiraterone, enzalutamide, and their combination-in patients with advanced prostate cancer. METHODS: A comprehensive search of PubMed, Embase, and the Cochrane Library was conducted to identify published randomized controlled trials (RCTs). Risk of bias was assessed using the Cochrane Risk of Bias tool. A random-effects model was employed to pool risk ratios (RRs) and 95% confidence intervals (CIs). Heterogeneity was quantified using the I statistic, and subgroup analyses were stratified by the specific ARAT regimen. Publication bias was evaluated utilizing funnel plots. RESULTS: Eight unique RCTs (comprising 9 published reports) involving 9,298 patients were included. The overall pooled analysis demonstrated a significantly increased risk of all-grade hypokalemia in patients receiving ARATs compared to controls (RR = 3.11, 95% CI: 1.88-5.15, P < 0.001; I = 91.9%). Subgroup analyses revealed that this risk was significantly elevated with abiraterone (RR = 3.25, 95% CI: 1.75-6.02, I = 88.3%) and the combination of abiraterone plus enzalutamide (RR = 4.62, 95% CI: 2.65-8.03, I = 48.6%), but not with enzalutamide (RR = 1.16, 95% CI: 0.96-1.39). Similarly, the risk of severe (grade ≥ 3) hypokalemia was significantly higher with ARAT treatment (RR = 4.54, 95% CI: 2.42-8.51, I = 48.4%); the risk signal was strongest in combination regimens (RR = 9.34, 95% CI: 1.71-50.90), although this estimate was based on limited data. CONCLUSION: Based on our preliminary findings, ARAT therapies, particularly abiraterone and combination regimens, are significantly related to the increased risk of hypokalemia in patients with advanced prostate cancer. Vigilant monitoring and the proactive management of serum potassium levels are strongly warranted in clinical practice.

Cancer is a systemic disease that perturbs the homeostasis of host tissues and organs, exerting manifestations both locally and distantly. Extracellular vesicles and particles (EVPs) have a pivotal role in intercellular communication between tumours and the host by transferring bioactive cargo to recipient cells, contributing to the systemic effects of cancer. Tumour-derived EVPs prepare distant organs for future metastasis, by creating a pre-metastatic niche (PMN). Additionally, tumours manipulate multiple organ systems to support their growth and evade immune detection. This co-option of host systems leads to cascading dysfunction across multiple organs, ultimately compromising host survival. Here we review the diverse systemic impact of cancer-associated EVPs, including immune dysregulation in PMNs, thrombosis and cardiovascular disease, liver metabolic dysfunction, glucose metabolism disorders, cachexia, and paraneoplastic syndromes of the nervous system. Furthermore, we discuss the intricate communication between host-, diet- and microbiota-derived EVPs and cancer cells, highlighting the complex interplay mediated by these EVPs in cancer progression and anti-cancer treatment responses. We also explore the prospects of EVPs as a systemic therapeutic approach for anti-cancer treatment. Overall, this Review highlights the need to address the systemic effects of cancer and to adopt holistic approaches to cancer treatment, by simultaneously targeting the tumour and its multi-organ paraneoplastic effects. These strategies hold great promise in mitigating the broad impact of disease progression and comorbidities and ultimately improving the quality of life and survival of patients.
