Objective To analyze the clinical, imaging, pathological characteristics and prognosis of renal mucinous tubular and spindle cell carcinoma (MTSCC), so as to provide preference for the differential diagnosis and clinical management of this disease.Methods A retrospective analysis was conducted on the clinical and follow-up data of 14 patients diagnosed with renal MTSCC at the Eastern Theater Command General Hospital during June 2021 and Aug.2025.Relevant literature was reviewed.Results Of the 14 patients, 10 were female (71.4%) and 4 were male (28.6%), with a mean age of 56.9 years. Pathological staging included pT1a in 6 cases, pT1b in 7 cases, and pT2b in 1 case.The median tumor diameter was 4.5 (range 2.0-11.0) cm.Twelve cases (85.7%) were asymptomatic and detected incidentally.On ultrasonography, most tumors exhibited well-defined margins and regular morphology (9/10, 90%) and appeared as homogeneous hypoechoic masses (7/10, 70%).All lesions demonstrated hypovascular features on imaging studies.Ten patients (71.4%) underwent laparoscopic radical nephrectomy, and 4(28.6%) received partial nephrectomy.Histologically, a distinctive architecture composed of tubular structures, spindle-shaped cells, and mucinous stroma was exhibited.Immunohistochemically, the positive rates of PAX-8, VIMENTIN and CK7 in tumor cells were 100% (13/13), 91.7% (11/12) and 84.6% (11/13), respectively.The Ki-67 proliferation index ranged from 2.0% to 40.0%.During a median follow-up of 25.0 (range4.9-0.0) months, no local recurrence or distant metastasis was observed.Conclusion Renal MTSCC is a rare subtype of renal cell carcinoma, typically lacking specific clinical symptoms and characterized by hypovascular imaging features.The tumor generally follows an indolent course with a favorable prognosis.For localized tumors, partial nephrectomy should be the primary consideration.For cases with high-risk pathological features such as sarcomatoid changes, due attention should be paid to the potential invasiveness and follow-up should be closely conducted.

Objective The aim of this study is to discuss the causal relationship between periodontal disease(PD)and prostate cancer(PCa).Methods A two-sample bidirectional Mendelian randomization(MR)analysis based on publicly statistical data from genome-wide association studies(GWAS)was conducted.MR Egger,weighted medium,simple mode and weighted mode were supplemented,while inverse variance weighted analysis(IVW)was the main method of analysis.Heterogeneity testing,pleiotropy testing and leave-one-out testing were used to assess the sensitivity and stabili-ty.Results The results of MR analysis showed that PD had no significant impact on the occurrence of PCa:East Asian(IVW,PD:OR=1.07,P=0.48);European(IVW,PD:OR=1.00,P=0.37,periodontitis:OR=1.03,P=0.14,chronic gingivitis:OR=0.99,P=0.37,chronic periodontitis:OR=1.03,P=0.22).The reverse MR analysis also did not show a causal relationship between PCa and PD:East Asian(IVW,PD:OR=0.97,P=0.22);European(IVW,PD:OR=0.84,P=0.44,periodontitis:OR=1.01,P=0.75,chronic gingivitis:OR=0.93,P=0.23,chronic periodontitis:OR=0.99,P=0.80).The results of other analysis were consistent with those of IVW analysis.Conclusions The results of our two-sample bidirectional MR analysis do not support a causal relationship between PD and PCa.

Purpose This study aimed to investigate the expression,function,and molecular mechanisms of ZNF384 in esophageal squamous cell carcinoma(ESCC),as well as its role in tumor progression and chemoresistance.Methods The expression of ZNF384 in ESCC cell lines and tissues was assessed using RT-qPCR.Correlations with TNM stage,invasion depth,lymph node metastasis,and prognosis were evaluated.In vitro assays were performed to examine the effects of ZNF384 on ESCC cell proliferation,migration,invasion,and chemosensitivity.Dual-luciferase reporter assays were conducted to determine the interaction between ZNF384 and FZD3,and to assess the activation of the Wnt signaling pathway.Results ZNF384 expression was significantly upregulated in ESCC cell lines and tissues(P<0.01).Elevated ZNF384 expression was associated with advanced TNM stage,greater invasion depth,lymph node metastasis,and poor prognosis(P<0.05).Functional assays demonstrated that ZNF384 overexpression promo-ted ESCC cell proliferation,migration,and invasion(all P<0.01),whereas ZNF384 knockdown inhibited these processes and enhanced chemosensitivity to cisplatin(all P<0.01).Mechanistic studies showed that ZNF384 directly bound to the FZD3 promoter,upregulated FZD3 expression,and activated the Wnt signaling pathway(P<0.05).Overexpression of FZD3 partially reversed the inhibitory effects of ZNF384 knockdown on cell malignancy and chemore-sistance(P<0.05).Conclusion ZNF384 promotes ESCC progression and reduces chemosensitivity through activa-tion of the FZD3/Wnt signaling pathway,suggesting its potential as a therapeutic target in ESCC.
