Introduction

Hematological malignancies, such as lymphoma and multiple myeloma, are marked by the uncontrolled proliferation of abnormal blood cells, leading to clinical manifestations like anemia, increased infection susceptibility, and bleeding disorders (Medical Masterclass Contributors, 2019; Jaffe, 2019). These malignancies present a considerable global health challenge, with incidence rates escalating (Zhang et al., 2023). This underscores the urgent need for aggressive therapeutic intervention (Ding et al., 2022; Rosenquist et al., 2023). In this context, bortezomib, a first-in-class proteasome inhibitor, has emerged as a pivotal component in the treatment of multiple myeloma. Its distinctive mechanism of action facilitates the degradation of essential proteins implicated in cell survival and proliferation (Syed, 2023). Bortezomib enhances existing treatments and offers significant benefits in combination regimens, improving the therapeutic landscape for patients with this challenging disease (Mateos et al., 2020).

While bortezomib has revolutionized the treatment of hematological malignancies, its use is frequently complicated by neurotoxicity, particularly peripheral neuropathy (Velasco et al., 2019; Badros et al., 2007). This side effect, ranging from mild sensory disturbances to debilitating pain, significantly impacts patients’ quality of life and can lead to treatment discontinuation (Burgess et al., 2021). Despite ongoing research into the mechanisms and management of bortezomib-induced neurotoxicity, the growing body of literature remains fragmented, making it difficult to identify overarching trends and critical gaps in knowledge (Meregalli, 2015).

To address this challenge, bibliometric analysis offers a systematic approach to mapping the intellectual structure, identifying influential studies, and uncovering emerging trends in the field (Cooper, 2015; Ninkov et al., 2022). Bibliometric indicators, when used alongside Altmetric analysis, provide a more holistic evaluation of research impact by incorporating social and public attention metrics in addition to traditional academic citations. The use of Altmetric analysis has gained prominence in recent years as a complementary tool to assess the broader influence of scholarly work, as demonstrated in studies such as Bagcier et al.’s analysis of the most-cited articles on ankylosing spondylitis (Bagcier et al., 2021).

However, no previous bibliometric or Altmetric analysis has specifically focused on the domain of bortezomib-induced neurotoxicity. This study aims to fill this gap by providing a comprehensive overview of global research efforts, highlighting clinical and research priorities to improve patient outcomes.

Materials and methods

Strategies for literature searching and data collection

A systematic search was conducted in the Web of Science Core Collection (WoSCC) on 4 September 2024, encompassing the period from 2002 to 2024 to identify pertinent literature. The following exact search string was used: (TS= (Bortezomib OR Velcade OR PS 341 OR LDP 341)) AND (TS=(neurotoxic* OR “peripheral neuropathy” OR “peripheral nerve toxicity”)). This search was limited to articles written in English to ensure accessibility and relevance to the study’s objectives. Full records and cited references were extracted in plain text format to enable a comprehensive analysis of the retrieved documents. The extracted data included details on the country or region of origin, the affiliated institution, the journal of publication, publication and citation dates, author details, and keywords, which were meticulously analyzed to achieve the study’s objectives.

Statistical analysis

Three software tools were employed due to their robust capabilities in statistical analysis and data visualization: VOSviewer (version 1.6.20), CiteSpace (version 6.3.R1), and R (version 4.3.3). VOSviewer was used to map institutional collaborations and co-authorships, facilitating the exploration of complex academic networks (van Eck and Waltman, 2010). Keyword co-occurrence analysis was conducted using VOSviewer, and keyword bursts were identified with CiteSpace. Duplicate removal during data preparation was performed using software-assisted methods to ensure data accuracy and consistency. The bibliometric analysis incorporated three key metrics for evaluating the scholarly impact of publications: h-index: A metric that reflects both the productivity and citation impact of an author’s publications, defined as the number of papers (h) with at least h citations each (Mondal et al., 2023); g-index: A measure of an author’s or journal’s publication performance, emphasizing highly cited articles, calculated as the largest number (g) such that the top g articles collectively received at least g2 citations (Ali, 2021); and m-index: A refinement of the h-index that accounts for the length of an author’s academic career, calculated as the h-index divided by the number of years since their first publication (Saba et al., 2023). This study is based on bibliometric data and does not involve human participants, animals, or sensitive personal information. Therefore, ethical approval was not required.

Discussion

This bibliometric analysis aimed to explore the global trends in the field of bortezomib-induced neurotoxicity by analyzing publications from 2002 to 2024.

General information

A notable peak in publication activity was observed in 2014, with 69 articles, indicating a significant surge in research interest. The decline in publication frequency observed after 2020 is intriguing and warrants further investigation. One plausible explanation is the saturation of research in certain areas, as foundational studies may have addressed key questions regarding bortezomib-induced neurotoxicity. Alternatively, the COVID-19 pandemic may have disrupted research activities and shifted funding priorities, diverting attention toward pandemic-related studies (Sohrabi et al., 2021). Changes in funding allocations for oncology research during this period could also have played a role. Future studies could explore these hypotheses in greater depth to better understand the factors influencing publication trends.

The analysis of national and institutional publications reveals a globally distributed research effort, with the United States and China leading in output, thereby highlighting key contributions to the scientific discourse (Attal et al., 2017; Richardson et al., 2003). The United States plays a central role in international collaborations, closely followed by France and Italy, which illustrates a robust global research network that facilitates intellectual exchange and resource sharing. Harvard University emerges as the preeminent institution for research output, consistent with its global reputation for innovation. Johnson & Johnson ranks as a significant second, while the Dana-Farber Cancer Institute stands out for its international collaborations, as evidenced by its high number of partnerships and significant citations in leading articles (Attal et al., 2017). These findings underscore the importance of global partnerships in advancing scientific research. For bortezomib-induced neurotoxicity, scholars from the United States and China substantially contribute to the scientific discourse. Notably, Richardson Paul G. possesses an h-index of 32, underscoring his significant contributions to this area, including a pivotal phase 2 study (Richardson et al., 2003; Voorhees et al., 2020; Grosicki et al., 2020; Gulla et al., 2021). His leadership in international collaborations exemplifies a broader trend in which impactful research emerges from global partnerships. This analysis elucidates how a select group of leading scholars profoundly shapes the global research landscape.

The journal landscape in the field of bortezomib-induced neurotoxicity is marked by a select group of influential publications that have played a pivotal role in shaping the scientific narrative. Notably, the New England Journal of Medicine has emerged as a preeminent outlet for this research, as evidenced by the fact that the 4 most-cited articles in this study were all published therein (Attal et al., 2017; Richardson et al., 2003; San Miguel et al., 2008; Moreau et al., 2016). This underscores the journal’s reputation for publishing high-impact studies that not only advance medical knowledge but also set the agenda for future research directions. However, it is important to note that citation counts may be influenced by journal self-citation practices and citation bias, which could overemphasize the impact of certain journals. Moreover, Blood and the Journal of Clinical Oncology have made significant contributions to the field, as indicated by their centrality in the co-occurrence and coupling networks of journals (Richardson et al., 2010; Fisher et al., 2006). These journals have been instrumental in publishing a substantial body of work that has expanded the understanding of bortezomib’s effects and facilitated important dialogues on treatment strategies and management protocols.

Keywords reflect hotspots and trends in the research field

The keyword co-occurrence analysis in this study reveals the centrality of certain concepts within the discourse on bortezomib-induced neurotoxicity. The prominence of “therapy” and “peripheral neuropathy” in the literature underscores the dual focus on treatment strategies and the management of a significant side effect associated with bortezomib use (Scott et al., 2016; Tan et al., 2019). These findings align with previous bibliometric studies, which similarly identified therapy strategies as a dominant research focus in disease-specific bibliometric analyses (Özduran and Hancı, 2022). This reflects the broader scientific community’s emphasis on developing therapeutic options that mitigate neurotoxicity while maintaining the drug’s oncological benefits (Yamamoto and Egashira, 2021). The keyword “multiple-myeloma” standing out with high occurrences and link strength reflects the disease’s focus in the body of literature under review (Scott et al., 2016). This prominence indicates extensive research efforts dedicated to understanding the disease’s pathology and developing effective treatment regimens (Scott et al., 2016).

The frequent appearance of “dexamethasone” in the literature indicates its widespread use as a component of combination therapies, likely due to its potent anti-inflammatory and immunosuppressive properties (Voorhees et al., 2020). Its presence in the network highlights the importance of corticosteroids in the treatment paradigm, potentially in efforts to ameliorate bortezomib’s neurotoxic effects. The co-occurrence analysis of keywords provides a landscape of research priorities in bortezomib-induced neurotoxicity, highlighting efforts to refine therapeutic strategies, manage side effects, and explore innovative treatments.

The prominence of “thalidomide” with a notable burst from 2005 to 2008 highlights a resurgence of interest in this compound (Oleinikovas et al., 2024). Historically associated with severe birth defects, thalidomide has been repurposed for its potential anti-cancer properties (Vargesson and Stephens, 2021). The citation burst suggests a reevaluation of thalidomide’s clinical applications, particularly in the treatment of multiple myeloma, where its immunomodulatory and anti-angiogenic effects are being scrutinized for potential therapeutic benefits (Moehler et al., 2006). The citation burst for “phase 2” (2006–2009) highlights a period of concentrated clinical development. Phase 2 trials are pivotal in determining the efficacy and dosing of new therapeutics, and this burst reflects significant investment during this critical trial phase. These findings suggest a focused effort within the scientific community to advance the drug development process, ensuring that promising compounds proceed to later stages of testing with a robust evidence base (Voorhees et al., 2023). The significance of keyword bursts, such as “lenalidomide” and “quality of life,” reflects evolving research priorities and therapeutic strategies. The burst for “lenalidomide” (2017–2024) underscores the growing interest in this therapeutic agent as a critical component in multiple myeloma treatment, highlighting its role in improving survival outcomes (Leonard et al., 2019; Flowers et al., 2020). Similarly, the emergence of “quality of life” as a burst keyword from 2017 onward marks a notable shift towards patient-centered outcomes in clinical research. This aligns with an increasing recognition that the impact of treatments on patients’ daily lives and wellbeing is as critical as traditional survival metrics (Author Anonymous, 2021). The clustering of terms such as “pain” and “open label” further emphasizes this trend, reflecting a research landscape that is increasingly focused on addressing patient needs and optimizing treatment protocols.

The steady increase in the prominence of the keyword “survival” since 2006, peaking in 2019–2021, underscores the enduring importance of survival data in oncological research. Survival remains a cornerstone endpoint in clinical trials, reflecting the ultimate goal of extending patients’ lives (Dufva et al., 2020; Zhao et al., 2022). Similarly, the keyword “efficacy,” which has been gaining traction since 2006 with a particular concentration since 2020, highlights the continuous quest for effective therapies. The intensified focus on efficacy in recent years may reflect the rapid evolution of treatment options, including immunotherapies and targeted agents, and the need to rigorously evaluate their benefits against standard care. This focus also suggests a concerted effort to optimize treatment protocols, ensuring that the most effective therapies are identified and adopted into clinical practice.

Strengths and limitations

The study has several notable strengths. By utilizing a comprehensive dataset from the WoSCC, it provides a reliable foundation for bibliometric analysis. The systematic investigation of keyword co-occurrence and coupling networks offers a nuanced understanding of the intellectual structure and thematic evolution of the field, highlighting research priorities, collaborative efforts, and emerging trends. The identification of burst keywords further underscores shifts in research focus, offering valuable insights for guiding future directions in bortezomib-induced neurotoxicity research. Additionally, the findings emphasize the growing focus on patient-centered outcomes, such as quality of life and pain management, which reflect a more holistic approach to cancer care. These insights have significant clinical implications, as they can inform future research funding strategies and the design of clinical trials in hematology. By identifying key research hotspots, this study provides clinicians and researchers with a comprehensive foundation for developing more effective treatment protocols and improving patient outcomes in the management of bortezomib-induced neurotoxicity.

However, several limitations warrant consideration. First, this study relied solely on the WoSCC database, which may have introduced biases or excluded relevant studies indexed in other databases such as PubMed or Scopus. The rationale for selecting WoSCC was its robust citation analysis tools and inclusion of high-impact journals, making it well-suited for bibliometric studies; however, future analyses could benefit from integrating multiple databases to enhance comprehensiveness. Second, only English-language articles and keywords were evaluated, which may have excluded important contributions published in other languages. Third, the time frame of the search (2002–2024) constrains the scope of the analysis, potentially overlooking the most recent developments in this rapidly evolving field. Fourth, duplicate removal and data cleaning were performed using automated, software-assisted methods without manual screening or quality assessment. This reliance on machine-based filtering may have introduced errors or overlooked nuances in study selection. Future studies could incorporate manual quality checks to mitigate this limitation.

Conclusion

This study delineates key contributions, influential studies, and collaborative networks in the field of bortezomib-induced neurotoxicity. The research hotspots identified — particularly therapeutic strategies and the management of peripheral neuropathy — underline the pressing clinical need for effective treatments and mitigation of side effects. Furthermore, the findings highlight the importance of international collaborations and patient-centered outcomes, providing a roadmap for future research efforts to advance the field.

Future research should focus on addressing gaps in under-represented regions and topics. Notably, while the United States and China lead in research output, contributions from low- and middle-income countries remain limited.
