摘要

背景/目的:睾丸癌,尤其是精原细胞瘤和非精原细胞瘤,一般预后良好,但也有一小部分患者会死亡。目前对与精原细胞瘤复发和预后不良相关的临床标志物的了解还很有限。趋化因子是肿瘤微环境中的关键蛋白,但对精原细胞瘤预后的研究还不够。此外,肿瘤浸润淋巴细胞(TILs)在癌症预后中起着关键作用,需要对精原细胞瘤进行进一步研究:对 25 例精索瘤患者和 24 例接受睾丸切除术的对照组患者的样本进行免疫组织化学(IHC)染色,检测趋化因子 CXCR4、CXCR5 及其配体 CXCL12、CXCL13 以及增殖标记物 Ki-67。研究了 IHC 结果与临床表现之间的关联:结果:精索瘤和正常睾丸的趋化因子谱不同。结果:精原细胞瘤和正常睾丸的趋化因子谱不同。TIL细胞质中CXCL13的表达量乘以每个样本中TIL的百分比,似乎与复发的可能性接近统计学意义:结论:TILs在精原细胞瘤生物学中的参与值得进一步研究,尤其是它们在肿瘤微环境和发病机制中的作用。TIL中的趋化因子和Ki-67表达可作为评估精原细胞瘤预后的潜在标志物。

Chemokine Profile Is Different in Normal Testis Compared to Seminoma - Especially in Tumor Infiltrating Lymphocytes.

Background/aim: Testicular cancers, particularly seminomas and non-seminomas, generally have a favorable prognosis, although a small subset of patients experience mortality. Current knowledge of clinical markers associated with relapse and poor prognosis in seminoma is limited. Chemokines, key proteins in the tumor microenvironment, are underexplored in seminoma prognosis. Additionally, tumor-infiltrating lymphocytes (TILs), which play a critical role in cancer prognosis, require further investigation in the context of seminoma.

Patients and methods: Samples from 25 seminoma patients and 24 control patients who underwent orchiectomy were immunohistochemically (IHC) stained for chemokines CXCR4, CXCR5, and their ligands CXCL12, CXCL13, and the proliferation marker Ki-67. The associations between IHC results and clinical presentations were examined.

Results: Chemokine profiles differed between seminoma and normal testis. The expression of chemokines in TILs in seminoma samples was especially over-expressed. The cytoplasmic expression of CXCL13 in TILs multiplied by the percentage of TILs in each sample, appeared to approach statistical significance concerning the likelihood of relapse.

Conclusion: The involvement of TILs in seminoma biology warrants further investigation, especially their role in the tumor micro-environment and pathogenesis. Chemokine and Ki-67 expression in TILs could serve as potential markers for assessing seminoma prognosis.

期刊介绍: ANTICANCER RESEARCH is an independent international peer-reviewed journal devoted to the rapid publication of high quality original articles and reviews on all aspects of experimental and clinical oncology. Prompt evaluation of all submitted articles in confidence and rapid publication within 1-2 months of acceptance are guaranteed. ANTICANCER RESEARCH was established in 1981 and is published monthly (bimonthly until the end of 2008). Each annual volume contains twelve issues and index. Each issue may be divided into three parts (A: Reviews, B: Experimental studies, and C: Clinical and Epidemiological studies). Special issues, presenting the proceedings of meetings or groups of papers on topics of significant progress, will also be included in each volume. There is no limitation to the number of pages per issue.
