All cases were admitted to Fujian Medical University Union Hospital from January 2012 to May 2023. <b>Results:</b> Of 7 PEHE cases, 2 underwent tumor biopsy and 5 underwent tumor resection. There were 4 males and 3 females, with a median age of 58 years old. Six cases showed multiple bilateral nodules, and only one case showed a single lesion in the lower left lung lobe. Five patients presented with respiratory symptoms, like cough, sputum, hemoptysis, shortness of breath. There were round-like solid lesions with clear border and homogeneous density on lung CT. Histologically, it showed nodular growth with a distinctive myxohyaline stroma. Necrosis was seen in the center of some cases. Epithelioid tumor cells were arranged in cords, solid pattern or single cells, with abundant eosinophilic cytoplasm and occasional intracytoplasmic vacuoles. The plasmacytoid nucleus were round to oval in shape with obvious nucleoli, minimal pleomorphism and few mitoses. The tumor cells were positive for vascular endothelial markers: CD31 (7/7), CD34 (5/7), ERG (6/6), and Fli-1 (5/6); CKpan was focally positive in 3 cases (3/7), and TFE3 in 2 cases. Ki-67 index ranged from 5% to 10%. Additionally, the tumor cells partially express PD-L1 in two cases. Moreover, lung carcinoma-related gene detection was negative in one case. The TFE3 break-apart probe in two cases did not display a split signal. In terms of treatment, 4 cases were treated with surgery, 1 case was treated with chemotherapy and surgery, and 2 cases were follow-up observation. After the median 34.4 months follow-up time, one was lost to follow-up, six were survived. Their CT scans showed slight enlargement of pulmonary nodules without other organ metastases. <b>Conclusions:</b> PEHE is a rare vascular-derived tumor, which is usually characterized by multiple solid bilateral nodules with slow growth. It tends to lack specific clinical symptoms, and is prone to be misdiagnosed as a metastatic carcinoma. Diagnosis primarily rely on pathology, with the use of an immunohistochemical package being crucial for definitive and differential diagnosis.</p>","PeriodicalId":39868,"journal":{"name":"中华肿瘤杂志","volume":"47 3","pages":"269-274"},"PeriodicalIF":0.0,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143671289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model was validated through tissue DNA extraction followed by polymerase chain reaction (PCR), sequencing, and western blot to confirm ANXA2 genotype and protein expression. The successfully constructed models were divided into a model group and a wild-type (WT) group for the creation of a mouse tail vein injection Lewis lung carcinoma (LLC) metastasis model.

This guideline integrates existing national standards for ovarian cancer diagnosis and treatment with evidence-based medicine and clinical expertise. Structured as a pathway framework, this guideline addresses hierarchical diagnosis and treatment, diagnostic workflows, therapeutic approaches, and follow-up protocols for ovarian cancer in county-level settings, offering 13 specific recommendations. The guideline clarifies the roles of county-level hospitals in ovarian cancer management, including primary diagnosis and treatment, administration of antitumor therapies, maintenance therapy, adverse event management, recurrence monitoring, rehabilitation guidance, two-way referrals, and follow-up. For cases beyond local capacity, timely referral to higher-level hospitals or qualified county-level facilities is advised. County-level hospitals may perform surgery for early-stage ovarian cancer, but suspected advanced-stage cases should be promptly referred. The guideline emphasizes the importance of multidisciplinary collaboration in county-level hospitals and recommend that initial chemotherapy for newly diagnosed patients should be conducted at higher-level or adequately equipped county-level institutions. Follow-up evaluations may be performed locally, but suspected recurrence or metastasis requires referral to higher-level hospitals for assessment. Detailed pathways are provided for diagnosis, treatment (including surgery, chemotherapy, maintenance therapy, and recurrence management), and follow-up, with recommendations for incorporating online follow-up methods to enhance patient monitoring. By defining the roles of county-level hospitals, standardizing referral processes, and strengthening multidisciplinary coordination, the guideline aims to promote standardized ovarian cancer care. Its implementation is expected to improve county-level hospitals' diagnostic and therapeutic capabilities, foster collaboration with higher-level institutions, and ultimately enhance patient outcomes and quality of life.

Univariate and multivariate logistic regressions were used to identify the independent influencing factors for ISUP pathological grading of prostate cancer. The receiver operating characteristic (ROC) curves were used to predict the efficacy between the high and low ISUP grades for prostate cancer. &lt;b&gt;Results:&lt;/b&gt; Of the 117 patients, 20 were in ISUP Group 1, 25 in Group 2, 18 in Group 3, 32 in Group 4, and 22 in Group 5.

In human MPNST cell lines ST-8814 (NF-1) and STS26T(sporadic), ARTN overexpression and low expression cell lines were constructed by transfecting ARTN overexpression plasmids and ARTN small interfering RNA (siRNA), respectively. The expression of ARTN mRNA was detected by real time quantitative polymerase chain reaction (RT-qPCR), the expression of the ARTN protein and Phosphoinositide 3-kinase(PI3K)/Akt signaling pathway related proteins were detected by Western blot. CCK-8 assay was used to detect cell proliferation ability, and cell invasion assay was used to detect cell invasion ability. The pathway proteins that interacted with ARTN were searched in the STRING database, and the functional pathways were clarified by Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The PI3K/Akt pathway specific inhibitor LY294002 was used to block the PI3K/Akt pathway of ST-8814 and STS26T cells to observe the changes in cell proliferation and invasion. &lt;b&gt;Results:&lt;/b&gt; Among the 51 MPNST tissue specimens, 22 cases showed a high expression of the ARTN protein and 29 cases showed a low expression of the protein. Higher expressions of the ARTN protein was associated with larger tumor diameters and disease progression (recurrence or metastasis) (both &lt;i&gt;P&lt;/i&gt;＜0.05). The median disease-free survival (DFS) of patients with a low expression of the ARTN protein was 26.2 months, and the median overall survival (OS) was 66.9 months. The median DFS and median OS of patients with a high expression of the ARTN protein were 10.7 months and 53.8 months, respectively. The log rank test results showed that the progression free survival rate of patients with a high expression of the ARTN protein was worse than that of patients with a low expression (&lt;i&gt;P&lt;/i&gt;=0.027), but the difference in overall survival rate between the two groups was not statistically significant (&lt;i&gt;P&lt;/i&gt;=0.790), which was also confirmed by Cox regression analysis. The CCK-8 assay results showed that after 48 hours of transfection, the absorbance (&lt;i&gt;A&lt;/i&gt;) values of ST-8814 and STS26T cells in the ARTN overexpression group were 1.35±0.01 and 1.10±0.02, respectively, which were higher than those in the empty plasmid control group (1.05±0.01 and 0.78±0.01, both &lt;i&gt;P&lt;/i&gt;＜0.01), while the &lt;i&gt;A&lt;/i&gt; values of ST-8814 and STS26T cells in the ARTN siRNA group were 0.35±0.01 and 0.61±0.01, respectively, which were low","PeriodicalId":39868,"journal":{"name":"中华肿瘤杂志","volume":"47 2","pages":"149-159"},"PeriodicalIF":0.0,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143411086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
