Purpose: Corneal melanoma (CM) is a rare malignancy that develops from melanocytes within the cornea, constituting a minority of all ocular tumors. In this study, we sought to investigate the clinicopathological characteristics correlated with the prognosis of CM patients. Methods: We collected patients with CM between 1983 and 2018 from the Surveillance, Epidemiology, and End Results (SEER) database. Cox proportional hazards regression was used for univariate analysis to value hazard ratio of malignant CM versus spindle cell melanoma and nodular melanoma subgroups. Kaplan-Meier survival analysis and log-rank test were also performed to identify additional prognostic markers and confirm the findings of the Cox hazard ratio. Results: A total of 29 eligible patients were collected in our study. Age at diagnosis, laterality, primary site, tumor size, the extent of disease, marital status, income, residential area, and treatment showed no significant prognostic factors for CM patients (p > 0.05). However, when concerned with the primary site of malignant melanoma, spindle cell melanoma and nodular melanoma were found to show significantly poorer prognosis in CM patients (both p < 0.05). Conclusions Age at diagnosis, laterality, primary site, tumor size, the extent of disease, and treatment were not significant prognostic indicators for CM patients. Spindle cell melanoma and nodular melanoma were notable for showing worse survival outcomes than malignant melanoma. Although the sample size in the SEER database was limited, our findings may provide motivation for tailoring individualized treatments for patients with CM with different primary sites.

Castleman disease (CD) is a rare and highly heterogeneous lymphoproliferative disorder, with clinical and pathological features ranging from asymptomatic localized lesions to life-threatening systemic inflammatory responses. In recent years, the classification system of CD has been increasingly refined, with both unicentric CD (UCD) and multicentric CD (MCD) expanding into multiple subtypes with distinct clinical characteristics. Although the classification framework has become more sophisticated, some subtypes still lack specific biomarkers, and the categorization of certain entities remains controversial. This review summarizes advances in CD classification approaches over the past years, explores the clinical features and identification of newly proposed subtypes, and analyzes current challenges, aiming to provide a reference for optimizing diagnostic and therapeutic strategies.

Objective To investigate the clinical characteristics,treatment responses,and prognosis of patients with idiopathic multicentric Castleman disease(iMCD)complicated by autoimmune hemolytic anemia(AIHA). Methods The patients diagnosed with iMCD in Peking Union Medical College Hospital from January 2010 to December 2023 and having complete baseline blood routine data were retrospectively enrolled in the study.The iMCD patients were further assigned into AIHA and non-AIHA groups based on baseline laboratory examinations,and the clinical characteristics and prognosis were compared between the two groups. Results A total of 341 patients with iMCD were enrolled in this study,including 277(81.2%)exhibiting anemia at baseline.Five(1.8%)patients were identified as having iMCD-AIHA,all of whom were iMCD-not otherwise specified type complicated by warm antibody-type AIHA,and two of them were simultaneously diagnosed with Evans syndrome.The timing relationship between the first onset of AIHA and iMCD diagnosis varied,with 2 patients experiencing their first hemolytic episode prior to the diagnosis of iMCD.In terms of treatment,the therapy targeting iMCD was effective in alleviating AIHA.The AIHA group had a poorer prognosis(HR=4.61,95% CI=1.08-19.80,P=0.040)and a lower 5-year survival rate(90% vs.60%,P=0.024)than the non-AIHA group.Conclusions iMCD-AIHA is clinically rare,and AIHA can occur at different stages of iMCD.Although the primary treatment principle remains targeting iMCD,great attention should be paid to the exacerbation of immune dysfunction caused by AIHA and the possible adverse prognosis it may bring.

Objective To explore the molecular mechanism of circular RNA(circ)VAPA promoting the Hippo pathway to inhibit liver regeneration through the miR-101a-3p/TEAD3 axis.Methods A mouse model of 70％partial hepatectomy-induced liver regeneration was constructed,and the expressions of circVA-PA,miR-101a-3p,and TEAD3 were analyzed.Mouse embryonic hepatocyte BNL CL.2 cells were transfected with siRNA or overexpression plasmids and divided into the VAPA-NC group,the VAPA-NC+miR-101a-3p mimic group,the VAPA-NC+miR-101a-3p mimic-NC group,the VAPA-OE group,the VAPA-OE+miR-101a-3p mimic group and the VAPA-OE+miR-101a-3p mimic-NC group.CCK-8 method and flow cytometry were used to analyze the proliferation,apoptosis,and cell cycle changes of hepatocytes.Immunofluorescence staining was used to analyze the nuclear translocation of YAP1.Quantitative Reverse Transcription Real-Time PCR(qRT-PCR)was used to analyze the expressions of key genes in the Hippo pathway.The dual-lu-ciferase reporter gene assay was used to verify the targeting relationships between circVAPA and miR-101a-3p,as well as between miR-101a-3p and TEAD3.Results The level of circVAPA gradually increased during liver regeneration(P＜0.05),while the level of miR-101a-3p first increased and then decreased(P＜0.05).When miR-101a-3p was overexpressed alone,the cell proliferation rate was the highest(P＜0.05),but it had no effect on the cell apoptosis rate(P＞0.05).When circVAPA was overexpressed alone,it had no effect both on the cell proliferation rate and apoptosis(P＞0.05).After co-overexpression of circVAPA and miR-101a-3p,the cell proliferation rate significantly decreased,and the cell apoptosis significantly increased(P＜0.05).When miR-101a-3p was overexpressed alone,a large number of cells entered into the S phase.After co-overex-pression of circVAPA and miR-101a-3p,a large number of cells were blocked in the G2/M phase.The phos-phorylation level of the Hippo upstream gene YAP1 significantly increased at 6 hours after liver regeneration(P＜0.05)and then rapidly decreased.However,co-overexpression of circVAPA and miR-101a-3p did not af-fect the level of p-YAP1 and the nuclear translocation of YAP1(P＞0.05).The expression levels of the Hip-po downstream gene CTGF and the transcription factor TEAD3 first increased and then decreased during liver regeneration(P＜0.05),and there was no significant change in CYR61(P＞0.05).After co-overexpression of circVAPA and miR-101a-3p,the expression level of CTGF increased(P＜0.05).Knocking down or overex-pressing circVAPA did not affect the expression of TEAD3(P＞0.05),while overexpressing miR-101a-3p could significantly inhibit the expression level of TEAD3(P＜0.05).The dual-luciferase reporter gene assay confirmed the targeting relationships between circVAPA and miR-101a-3p,as well as between miR-101a-3p and TEAD3.Conclusion circVAPA promotes the Hippo pathway to inhibit liver regeneration through the miR-101a-3p/TEAD3 axis.
