Introduction
Breast cancer stands as one of the most prevalent malignant neoplasms affecting women today.According to the latest data from the Centers for Disease Control and Prevention (CDC), breast cancer constitutes 31% of new cases among female tumor patients in the United States, claiming the highest incidence rate (1,2).China is witnessing a substantial increase in the rate of breast cancer incidence, with a consistent rise observed in recent years (3).The advent of advanced medical technologies has led to a noteworthy improvement in the survival rates of breast cancer patients.Correspondingly, the mortality rate associated with breast cancer has experienced a consistent decline, culminating in a projected five-year survival rate of 90% for breast cancer survivors in the United States by 2022 (1).This progress underscores the positive impact of ongoing advancements in medical science on the prognosis and outcomes of individuals grappling with breast cancer.
Breast cancer treatment, encompassing axillary lymph node biopsy, clearance, and radiation therapy, can induce disruptions in lymphatic circulation, leading to secondary lymphedema in the upper extremities.Postoperative upper limb lymphedema, commonly referred to as BCRL, significantly impacts the longterm quality of life for survivors and stands as one of the most prevalent postoperative complications following breast cancer interventions.BCRL exerts a profound influence on the wellbeing of breast cancer patients (4).Manifestations of this condition include limb swelling, pain, and functional limitations, contributing to a substantial decline in the overall quality of life.The persistent symptoms associated with BCRL further give rise to adverse psychological outcomes, including heightened levels of anxiety and depression among affected individuals (5,6).
Owing to the existing lack of uniform and standardized diagnostic and measurement criteria for BCRL, coupled with the continual introduction of novel assessment instruments and devices, the clinical conditions of patients participating in various studies, encompassing surgery, radiotherapy, and extended radiotherapy, have resulted in a broad spectrum of reported incidence rates.Secondary lymphedema following breast cancer treatment has been documented in reports spanning a wide range, from 2% to 83%.Several investigations have highlighted that the risk of lymphedema is markedly lower in cases of breast-conserving surgery compared to radical mastectomy, sentinel lymph node biopsy in contrast to axillary lymph node dissection, and regional lymph node irradiation versus extended irradiation (7,8).The incidence of BCRL varies from 3% to 36.7% with regional lymph node irradiation and 10% to 50% following axillary dissection (9,10).Patients with BCRL commonly report a range of symptoms, with 88% experiencing swelling, 72% tightness, 60% heaviness, and 40% numbness (11).The presence of BCRL significantly diminishes the quality of life for affected individuals, impacting body image and contributing to psychological issues such as depression and anxiety.Studies examining the economic burden of BCRL have underscored the occurrence of recurrent infections, substantially increasing healthcare expenditures for patients and complicating the treatment process (12, 13).
In recent years, there has been a gradual increase in the number of publications addressing BCRL, presenting a challenge for scholars seeking to swiftly comprehend the key issues and prevailing trends in BCRL research.Bibliometric analysis is recognized as a quantitative statistical tool that delineates the knowledge structure and identifies keyword trends within a specific research domain (14).Employing bibliometrics allows researchers to generate a comprehensive overview of the global distribution of countries, institutions, authors, and journals engaged in a particular research topic.This approach enables the visualization of hot topics and emerging trends in BCRL research, providing clinicians with evidence-based decision-making capabilities.Recognizing the need for a more robust quantitative analysis of BCRL-related literature, this study aims to delineate the global scientific output of BCRL research from 2003 to 2022.The study further seeks to provide quantitative insights into countries, institutions, journals, authors, and keywords, with the overarching goal of summarizing research hotspots and trends in BCRL.Anticipating that this analysis will offer valuable research references for future scholars, our objective is to contribute to the advancement of knowledge in this critical area of medical research.

Research strategy and data collection
The literature for this paper was sourced from the Web of Science (WoS), a repository encompassing over 20,000 high-quality and influential scholarly journals spanning 250 disciplines globally.The database, equipped with comprehensive citation indexing records, offers a robust platform for data mining and co-citation analysis (15).Recognized for its authority as a data source in bibliometric analysis, the Web of Science stands as a preferred choice due to its extensive coverage of scholarly publications, making it the primary selection for bibliometric investigations (16,17).
The main focus of our study is the research trends in BCRL over the past 20 years.Therefore, we conducted a systematic search and retrieval of relevant publications from January 2003 to December 2022 using the Science Citation Index Expanded (SCI-E).The search strategy employed the following parameters: TI= (lymphedema breast cancer OR BCRL), language=all, document type=articles or reviews.Additionally, we screened titles and abstracts for inclusion and exclusion criteria.Inclusion criteria were as follows: (1) Published between January 1, 2003, and December 31, 2022; (2) Limited to articles and reviews; (3) Content primarily focused on BCRL.Exclusion criteria were as follows: (1) Duplicate publications; (2) Non-article documents (such as book reviews, notices, editorials, conference abstracts, conference papers, letters, etc.).Two authors independently classified the extracted data.In cases of disagreement, a third author participated in discussions to reach a consensus.As of December 31, 2022, a total of 803 publications were successfully retrieved from the specified databases.The literature search methods and screening process are illustrated in the flow diagram of the searching process (Figure 1).
This study included a total of 803 papers, and the records were exported as "plain text files."The export format comprised "complete records and cited references," and the files were saved in "download_txt" format.

Knowledge visualization analysis
This study employed CiteSpace, VOSviewer, and Microsoft Excel 2021 for quantitative and visual analysis.VOSviewer, a tool for analyzing key information from a substantial number of publications, was utilized to construct collaborative, co-citation, and co-occurrence networks (18).Node size in these networks indicates the number of publications, line width represents the strength of relationships, and node color signifies distinct clusters or cycles.CiteSpace, focusing on the fundamental analysis of scientific literature, serves as a visual analytics tool expanding into the realms of data visualization and scientometrics.In this study, CiteSpace was employed to generate knowledge networks, citation paths, and to detect bursts in references and keywords (19).Evaluation metrics included citation bursts, co-citation citation clustering networks, and keyword bursts.The emergence of keyword bursts or citations implies frequent appearance or citation over time, signifying topics that have garnered significant attention from researchers.As such, these bursts can be considered research hotspots or frontiers (20).Leveraging these indicators, crucial topics, recent advancements, and emerging trends in the field were effectively identified.
In this study, VOSviewer (1.6.19) and CiteSpace (6.2.2) software were used to visualize and analyze the BCRL-related literature in the WOSCC database and to draw a knowledge map, aiming to understand the current status of research, research hotspots, and development trends in the field, and to provide a reference for future research.

Analysis of institutions
In Figure 4, the visualization depicts the volume of publications and various clusters of issuing organizations.Node size corresponds to the number of publications, line width indicates relationship strength, and node color signifies distinct clusters or cycles.The institutional analysis graph reveals that 110 institutions have contributed more than 3 publications each, collectively contributing 779 articles, which constitutes 97.01% of the total document count.The leading 10 institutions in terms of article numbers have published a combined total of 222 articles, representing 27.65% of the overall count.Most of the top 10 institutions, primarily research and clinical institutions, are based in the United States, maintaining robust collaborative relationships.The institution with the highest number of articles is Mayo Clinic, contributing 35 articles, followed by the University of Missouri and the University of Pennsylvania with 30 articles each.While China ranks second globally in terms of the overall number of articles, the issuing institutions appear relatively dispersed, with smaller article counts per institution, suggesting a need for strengthened collaboration.

Analysis of journals
Academic journals serve as the conduit through which researchers disseminate their findings, playing a crucial role in reflecting the quality of research.To ensure a comprehensive analysis for mapping, journals with six or more articles were selected, resulting in the inclusion of 35 eligible journals.Lymphatic Research and Biology emerged as the journal with the  highest article count, boasting 94 articles, equivalent to 11.71% of the total, followed by Supportive Care in Cancer with 47 articles, constituting 5.85% of the total.Among these, 10 journals contributed more than 10 articles each, while the remainder had less than 10 articles.In Figure 5A The dual-map overlay analysis depicted in Figure 5B illustrates the coverage of all academic journals, mapping the citation paths across various subject areas.Labels on the left side of the dual-map overlay signify the disciplines covered by the citing journals, while labels on the right side represent the disciplines of the cited journals.The majority of journals, originate from the fields of surgery, dermatology, ophthalmology, medicine, medical sciences, and clinical areas, called research frontier.Cited papers predominantly stem from journals in the areas of molecular, biology, genetics, health, nursing, medicine, sports, rehabilitation, referred to as the Knowledge Base.The boundaries between citing and cited journals denote the communication and connection between the two, with node labels indicating the disciplines encapsulated by different journals.The unsloped axis of the ellipse signifies the number of authors involved, while the vertical axis denotes the number of published journals.This dual-map overlay analysis provides insights into the interdisciplinary nature of BCRL-related research and the diverse range of disciplines contributing to and influenced by this field.3.Among these authors, Taghian, Alphonse G., affiliated with Harvard Medical School and Oncology Radiology at Massachusetts General Hospital, emerges as the most prolific collaborators and   The primary focus of this article was on the prospective screening for lymphedema in a large group of breast cancer patients, revealing that regional lymph node radiotherapy (RLNR) significantly increased the risk of lymphedema compared to breast/chest wall radiotherapy alone.The conclusion emphasized the need for clinicians to carefully weigh the potential benefits of RLNR for disease control against the increased risk of lymphedema (25).

Analysis of authors
Ridner, Sheila H., stands out as the author with the secondhighest number of publications.Her research, focusing on the assessment of postoperative lymphedema in breast cancer and encompassing literature on health education and nursing care, has achieved notable recognition, reflected in a high citation rate.This suggests that her work has played a pivotal role among numerous authors and has left a substantial impact in the field (26-28).One of Ridner's seminal articles, titled "Incidence, Treatment Costs, and Complications of Lymphedema After Breast Cancer Among Women of Working Age: A 2-Year Follow-Up Study," holds the distinction of receiving the highest number of citations, totaling 339.This study delves into the economic burden, incidence of lymphedema, and associated risk factors for BCRL among women of working age (29).The article, published in the Journal of Clinical Oncology, achieved a Collaborative network of authors.

Analysis of keywords and strongest burst keywords
Through the analysis of keyword evolution and frequency changes, it is possible to pinpoint research frontiers and emerging themes.Keywords exhibiting high frequency and centrality values signify research hotspots in the past 20 years, while those with high citation explosiveness can foreshadow future research frontiers.
In Figure 7A, VOSviewer categorizes 129 keywords into six clusters.As of the end of 2022, "lymphedema," "breast cancer," and "women" stand out as the top three high-frequency keywords.Figure 7B, utilizing CiteSpace with the classic log-likelihood ratio (LLR) algorithm, results in 11 clusters.With Q = 0.4569 and S = 0.7848, values exceeding Q > 0.3 and S > 0.5 signify significant clustering within the network, indicating consistent literature within each clustered topic.The largest cluster, #0, is centered around "mild arm lymphedema", with additional subtopics including "lymphaticovenular anastomosis" and "complex decongestive therapy".
Figure 8 highlights the top 25 keywords with the strongest citation bursts.The left endpoint of the red line denotes the time of emergence, while the right endpoint indicates the endpoint.Recently emergent keywords underscore current research hotspots, emphasizing "complex decongestive therapy," "prevention", and "reconstruction" as key focuses and frontiers in future BCRL-related research.

Analysis of references
The reference co-citation map serves as a valuable tool for exploring closely related research topics within the academic field.Figure 9 includes a total of 10,648 cited articles, and 224 articles meet the criterion of having a minimum number of citations of at least 20.The citation frequency of an article serves as a gauge of its academic significance and impact, with higher citation frequencies indicating increased attention and influence.
Figure 10 highlights the top 25 literature with the strongest citation bursts.These bursts, characterized by sudden increases in citation frequency at different times, signify current research hotspots.Analyzing these references provides insights into ongoing research trends and allows for predictions regarding future developments in the field.
In Table 4, the most highly cited recent article, published in Lancet Oncology, is titled "Incidence of unilateral arm lymphoedema after breast cancer: a systematic review and metaanalysis."The authors conducted an analysis that included 72 studies, concluding that the incidence of postoperative lymphedema after breast cancer is approximately 16.6%.However, when considering only 30 prospective studies, the incidence rises to 21.4%, suggesting that prospective studies offer a more accurate reflection of BCRL incidence.The article highlights the impact of the timing of patient inclusion on incidence results, as BCRL manifests acutely for some patients and chronically for others.Factors such as the method of diagnosing lymphedema and the demographic composition of the study population, particularly noting that 13 of the 30 prospective studies focused on North American women, contribute to variations in reported incidence rates.The article underscores the likelihood of underdiagnosis of lymphedema, emphasizing the importance of early detection and management through increased research efforts.Patients can be monitored for lymphedema at 3-to 6-month intervals within the first 2 years of onset, utilizing tools such as bioelectrical impedance spectroscopy (BIS) to measure changes in intra-and extracellular water.The article identifies more extensive surgery (involving the chest wall and axilla) and factors such as overweight or obesity as associated with an increased risk of lymphedema.Modest evidence also supports adjuvant therapies (such as radiation and chemotherapy) and sedentary lifestyles as additional risk factors.The article suggests that future studies could delve deeper into the risk factors for lymphedema development and refine the impact of different treatments on incidence rates (30).

Discussion
Bibliometrics serves as a systematic tool for delving into academic literature and research findings within related fields.Through literature analysis, it became apparent that despite the substantial number of clinical trials conducted in the realm of BCRL, there exists a dearth of bibliometric studies addressing this specific topic.The application of bibliometric analysis has facilitated an evaluation of the quality of existing studies within the available literature, offering insights into current research activities and shedding light on the level of evidence, impact levels, and potential impact factors.The bibliometric analysis of BCRL has proven invaluable in uncovering trends within the discipline and charting the evolution of research.This, in turn, aids researchers in

Top 25 Keywords with the Strongest Citation Bursts.In the realm of BCRL, the United States emerges as the leading contributor in terms of publications, boasting 286 articles, followed by China with 86.The Mayo Clinic stands out as the most prolific research organization, contributing 32 articles, and notably, many of the institutions with substantial publication numbers are based in the U.S.Among individual authors, Taghian, Alphonse G., holds the top position with the highest number of published articles, totaling 24.His contributions also lead in terms of citations, amassing a remarkable 1,240, indicative of significant impact and fostering collaborative relationships with other scholars.Examining the current classification of BCRL topics reveals that predominant research areas include oncology, physiology, surgery, rehabilitation, and immunology.Based on the insights gleaned from econometric analysis, the study concludes that the primary research hotspots in BCRL presently revolve around complex decongestive therapy, prevention, and reconstruction.

Complex decongestive therapy
Complex Decongestive Therapy (CDT) represents a comprehensive treatment approach for BCRL and currently stands as the standard in BCRL management.CDT comprises four integral steps, encompassing skin care, freehand lymphatic drainage, compression bandaging, and functional exercise (39-41).A multitude of scholarly investigations has been dedicated to the study of CDT, evaluating its efficacy through various means.Some studies have focused on assessing the effectiveness of CDT using ultrasound (42,43) or BIS (44) to gauge its impact on edema reduction.Additionally, comprehensive evaluations of CDT's effects on pain, quality of life, mood, and fatigue in BCRL patients have been conducted (45,46).Notably, one study highlighted the positive impact of upper body resistance exercise integrated into intensive CDT lymphedema treatment.This intervention was found to enhance arm function and muscle strength without causing an increase in arm volume in patients with BCRL (47).

Prevention
Surgical prophylaxis in the context of breast cancer involves the identification of sentinel lymph nodes using near-infrared (NIR) fluorescence of indocyanine green (ICG), proving to be a valuable technique.NIR fluorescence holds promise as a key tool for both the prevention and management of lymphedema following axillary dissection for breast cancer.A study by Abbaci et al. (48) encompassed a total of 2016 patients.The application of ICG imaging for axillary reverse labeling was deemed safe for all 951 patients, with arm lymph nodes successfully identified in 80%-88% of those undergoing axillary lymph node dissection.This technique not only serves as a diagnostic tool with high sensitivity and specificity for lymphedema but also finds utility in staging, intraoperative mapping, and patency control of lymphatic foramen anastomosis.The findings underscore the potential of NIR fluorescence with ICG as a multifaceted approach in breast cancer surgery, offering both diagnostic and procedural advantages.
Early screening and prevention with BIS have been the focus of numerous studies aiming to identify individuals at high risk for BCRL.Implementing BIS for early identification and subsequent conservative interventions in high-risk breast cancer patients has shown promising results, notably contributing to a significant reduction in the incidence of BCRL.These findings advocate for the importance of early prospective screening and intervention as effective measures in managing BCRL.The evidence suggests that early detection facilitated by patient-oriented interventions holds the potential to improve patient prognosis and mitigate the risk of persistent BCRL (49)(50)(51).This underscores the significance of incorporating BIS into proactive strategies for early screening and intervention, ultimately enhancing patient outcomes in those at heightened risk for BCRL.
Ridner, Sheila H. ( 28) devised a trial-specific methodology to investigate the impact of early intervention utilizing BIS and to compare it with the effect of combined early intervention with tape measurements.The intervention involved using a compression garment for 4 hours per day over a 12-week period, with the primary endpoint being the incidence of clinical lymphedema.Clinical lymphedema was defined as an incidence requiring CDT, characterized by a ≥ 10% change in volume from the pre-surgical baseline on the tape measure in the high-risk arm.A total of 508 patients participated in this analysis, with 109 (21.9%) triggering Exercise and early rehabilitation play pivotal roles in the prevention of BCRL (52-55).Rehabilitative exercises, emphasizing mobility, and physical activities focusing on strength are actively encouraged to mitigate the risk of BCRL.Incorporating these measures into the management and care of individuals with breast cancer not only supports overall physical well-being but also serves as an integral aspect of preventive strategies against lymphedema-related complications.
Weight control is recognized as a crucial aspect in preventing BCRL (56-58).Maintaining a stable weight and avoiding overweight and obesity are advised preventive measures.For individuals who are overweight or obese, offering dietary guidance to reduce body mass index is recommended.Implementing a structured exercise program and adhering to a prescribed diet are significant contributors to achieving successful weight loss and its maintenance.Obese breast cancer survivors may particularly benefit from weight loss interventions, not only in reducing their risk of lymphedema but also in enhancing their overall health (59).Emphasizing weight control strategies is integral to comprehensive care for breast cancer patients, contributing to both lymphedema prevention and broader health outcomes.

Reconstruction
In a clinical study conducted by CARD A et al. (60) involving 574 cross-matched patients, 78 individuals (6.8%) developed lymphedema, with 21 cases occurring in reconstructed breasts and 57 in non-reconstructed breasts.Notably, patients who did not undergo reconstruction were significantly more likely to develop BCRL (9.9% vs. 3.7%, p < 0.001).Furthermore, the onset of lymphedema occurred significantly later in reconstructed patients compared to non-reconstructed patients (p < 0.001).This study suggests that patients who underwent breast reconstruction exhibited a lower incidence and delayed onset of breast cancerassociated lymphedema compared to those who underwent mastectomy alone.
In surgical interventions, lymph node or lymphatic vessel reconstruction is often incorporated alongside breast reconstruction.Lymphatic venous anastomosis (LVA) stands out as a minimally invasive procedure designed to redirect lymph to the dermal venous drainage system.This technique demonstrates notable improvements in volume and, in specific cases, may obviate the need for compression therapy.LVA not only significantly enhances quality of life but also positively impacts the patient's mood and self-perception (61).Vascularized lymph node transfer (VLNT) represents another microsurgical approach frequently combined with autologous free flap breast reconstruction.This technique aims to address lymphedema and brachial plexus neuropathy while minimizing the risk of cellulitis (62).The synergistic application of LVA and VLNT, possibly in conjunction with other methods, optimizes their effectiveness.Moreover, vascularized lymphatic vessel transfer (VLNT) involves harvesting specific lymphatic vessels while preserving lymph nodes at the donor site.VLNT is typically reserved for patients lacking functional lymph nodes in the affected limb and for whom lymphatic vessels are no longer amenable to LVA treatment.Current literature supports the efficacy of VLNT, indicating a significant 40% reduction in BCRL volume in approximately 90% of patients (63,64).
Two relatively recent surgical strategies include immediate lymphatic reconstruction (ILR) during axillary lymph node dissection and the combination of vascularized lymph node transfer with Deep Inferior Epigastric Artery (DIEP) flap breast reconstruction.Immediate Lymphatic Reconstruction (ILR), also known as the Lymphatic Microsurgical Prophylactic Healing Approach (LyMPHA), involves performing prophylactic lymphovenous anastomosis at the time of axillary lymph node dissection (ALND).While several techniques have been proposed for managing lymphedema after its onset, the prophylactic application of ILR aims to decrease the risk of development to 6.6% (65).Furthermore, the combination of vascularized lymph node transfer with DIEP flap breast reconstruction offers notable improvements in lymphedema-related quality of life, even without a reduction in volume difference.This approach also results in reduced dependence on compression garments and a decreased requirement for physical therapy (66).

Limitation
Several limitations of this study should be acknowledged.Firstly, we exclusively relied on data from the Web of Science (WOS) and did not consider literature from other databases.Secondly, due to time constraints, literature outside the specified period was excluded.Additionally, software limitations may have prevented the modification of case formats and abbreviations, and the settings of thresholds and cropping methods might have led to the inadvertent exclusion of some data.

Conclusion
Our comprehensive bibliometric analysis of Breast Cancer-Related Lymphedema (BCRL) research from 2003 to 2022 offers valuable insights into the evolving landscape of this field.The study revealed a consistent upward trend in BCRL publications, peaking in 2018, with the United States emerging as the predominant contributor.Collaborative networks among researchers and institutions worldwide underscore the global nature of BCRL research.Noteworthy research hotspots identified encompass preventive strategies, complex decongestive therapy, and reconstructive interventions.These findings underscore the multidimensional approach required to address the complexities of BCRL management effectively.
In summary, this study provides a comprehensive overview of BCRL research trends and collaborations globally.It serves as a foundational resource for researchers, clinicians, and policymakers, fostering evidence-based practices and interventions for BCRL in the future.By emphasizing an evidence-based approach, this study aims to provide valuable insights into the field and offer an exploratory analysis to further advance BCRL research.
