Abstract

Purpose: The Journal of Neuro-Oncology (JNO), established in 1983, plays a key role in publishing research on brain and spinal cord tumors. This study examines JNO's publication trends, focusing on country and gender representation to highlight its global impact.

Methods: Statistical analyses were conducted using R. Gender of the first authors was predicted using a gender-guesser, and author affiliations were used to determine publication countries. We introduced a novel Country-Related Diversity (CRD) index to assess the JNO's representativeness, comparing a country's JNO publications to its overall neurosurgical output. An index value of 1 indicates proportional representation.

Results: The JNO corpus, spanning from 1983 to 2024, comprises 8,154 documents with an average document age of 14.4 years. The average citation count per document is 28.71, with a rate of 2.16 citations per document per year. JNO's scientific output has grown significantly, peaking at 397 articles in 2011, with a long-term annual growth rate of 3.7%. The keyword analysis highlights "glioblastoma" as the most frequent term, reflecting the journal's neuro-oncological focus. Geographically, the U.S. led with 2,535 articles (40.1%), followed by China and Germany. International collaboration rose steadily, with multi-country publications increasing from 4.76% in 1983 to 20.98% in 2024. Analyzing contributions from different countries showed a converging CRD index toward 1 (P < 0.01), with U.S. and non-U.S. countries trending similarly. Upper-middle-income countries displayed fluctuating CRD patterns, whereas lower-middle-income countries lagged behind. Authorship analysis showed an increasing trend in co-authorship (P < 0.01), with the average number of authors per paper reaching 10.4 by 2024. Gender representation revealed a growing number of female first and senior authors, although males still dominate. By 2024, 32.9% of first authors and 21.6% of senior authors were female, signaling a gradual trend toward gender parity (P < 0.01).

Conclusions: The CRD index offers a standardized measure of country-specific research representation in the JNO. The convergence towards 1 reflects balanced international representation. JNO publication also reflects a trend toward gender equity, with a notable rise in female first authors, enhancing global research inclusivity.

神经肿瘤学》期刊发表文章的长期趋势：对神经肿瘤学领域核心期刊的书目研究。

目的：《神经肿瘤学杂志》（JNO）创刊于 1983 年，在发表脑肿瘤和脊髓肿瘤研究成果方面发挥着重要作用。本研究探讨了 JNO 的出版趋势，重点关注国家和性别代表性，以突出其全球影响力：使用性别猜测器预测第一作者的性别，并使用作者所属单位确定发表论文的国家。我们引入了一个新颖的国家相关多样性（CRD）指数来评估JNO的代表性，将一个国家的JNO论文发表量与其神经外科总产量进行比较。结果：JNO 语料库的时间跨度为 1983 年至 2024 年，包含 8,154 篇文献，平均文献年龄为 14.4 年。每篇文献的平均引用次数为 28.71 次，每年每篇文献的引用次数为 2.16 次。JNO 的科学产出增长显著，2011 年达到 397 篇的峰值，长期年增长率为 3.7%。关键词分析显示，"胶质母细胞瘤 "是出现频率最高的词汇，反映了该期刊对神经肿瘤学的关注。从地域来看，美国以2535篇文章（40.1%）居首，其次是中国和德国。国际合作稳步上升，多国出版物从1983年的4.76%增至2024年的20.98%。对来自不同国家的投稿进行分析表明，CRD指数趋向于1（P结论）：CRD 指数是衡量各国在 JNO 中研究代表性的标准化指标。向 1 的趋同反映了国际代表性的平衡。JNO 出版物也反映了性别平等的趋势，女性第一作者显著增加，增强了全球研究的包容性。

期刊介绍： The Journal of Neuro-Oncology is a multi-disciplinary journal encompassing basic, applied, and clinical investigations in all research areas as they relate to cancer and the central nervous system. It provides a single forum for communication among neurologists, neurosurgeons, radiotherapists, medical oncologists, neuropathologists, neurodiagnosticians, and laboratory-based oncologists conducting relevant research. The Journal of Neuro-Oncology does not seek to isolate the field, but rather to focus the efforts of many disciplines in one publication through a format which pulls together these diverse interests. More than any other field of oncology, cancer of the central nervous system requires multi-disciplinary approaches. To alleviate having to scan dozens of journals of cell biology, pathology, laboratory and clinical endeavours, JNO is a periodical in which current, high-quality, relevant research in all aspects of neuro-oncology may be found.
