Characterization of global research trends and prospects on platinum-resistant ovarian cancer: a bibliometric analysis

Abstract

BackgroundIn the last decades, growing attention has been focused on identifying effective therapeutic strategies in the orphan clinical setting of women with platinum-resistant ovarian cancer (PROC), generating thousands of original articles. However, the literature involving bibliometric analysis of PROC has not been published yet.ObjectiveThis study hopes to gain a better understanding of the hot spots and trends in PROC by conducting a bibliometric analysis, as well as identify potential new research directions.MethodsWe searched the Web of Science Core Collection (WOSCC) for PROC-related articles published between 1990 and 2022. CiteSpace 6.1.R2 and VOS viewer 1.6.18.0 were primarily utilized to evaluate the contribution and co-occurrence relationships of various countries and regions, institutes, and journals and to identify research hotspots and promising future trends in this research field.ResultsA total of 3,462 Web of Science publications were retrieved that were published in 671 academic journals by 1135 authors from 844 organizations in 75 countries and regions. The United States was the leading contributor in this field, and the University of Texas MD Anderson Cancer Center was the most productive institution. Gynecologic Oncology was the most productive journal, while the Journal of Clinical Oncology was the most cited and influential. Co-citation cluster labels revealed the characteristics of seven major clusters, including synthetic lethality, salvage treatment, human ovarian-carcinoma cell line, PARP inhibitor resistance, antitumor complexes, folate receptor, and targeting platinum-resistant disease. Keywords and references burst detection indicated that biomarkers, genetic and phenotypic changes, immunotherapy, and targeted therapy were the most recent and most significant aspects of PROC research.ConclusionThis study conducted a comprehensive review of PROC research using bibliometric and visual techniques. Understanding the immunological landscape of PROC and identifying the population that can benefit from immunotherapy, especially in combination with other therapeutic options (such as chemotherapy and targeted therapy), will continue to be the focal point of research.

A bibliometric analysis of cardiotoxicity in cancer radiotherapy

“…It is a text mining method based on artificial intelligence algorithms that assesses the interrelationships and impacts of publications and uses mathematical and statistical techniques to identify and organize knowledge structure ( 12 ). It not only provides quantitative statistical analysis of publications in a specific field but also helps readers understand the development of the discipline and visualize the frontiers through mapping ( 13 ). Bibliometrics plays a crucial role in biomedical disciplines like inflammation, genetics, and cancer, aiding in illness treatment and the development of clinical guidelines ( 14 – 16 ).…”

p27 Kip1 and cytoplasmic pSer10p27 are promising biomarkers for predicting prognosis and chemotherapy response in ovarian cancer

“…Ovarian cancer is one of the most lethal malignancy of the female reproductive system worldwide (Duan et al 2023). Due to the lack of early diagnosis methods, more than 70% of patients reach advanced stages at the time of diagnosis (Dochez et al 2019).…”

Application of medical imaging in ovarian cancer: a bibliometric analysis from 2000 to 2022

“…This methodology allows not only the evaluation of research quality but also the identification of developing research trends and the prediction of possible future research directions ( 11 , 12 ). Previous studies have utilized bibliometric analysis to examine prominent research topics and studies concerning OC ( 13 – 15 ). Duan’s research revealed that platinum-resistant OC is primarily focused on identifying populations that can benefit from immunotherapy alongside the practical implementation of immune checkpoint inhibitors ( 13 ).…”
