Objective:
Liquid biopsy has revolutionized cancer research, diagnosis, and personalized treatment. This study aimed to explore regional contributions and disparities in this rapidly advancing field.
Method:
The Scopus database was utilized for data retrieval in June 2024. A total of 2761 documents, including 1605 articles and 1156 reviews, were analyzed. These documents received 70,837 citations with h-index of 105.
Results:
Europe was the most prolific region, contributing 1645 documents with 53,728 citations and an h-index of 94. Asia followed with 607 documents, receiving 17,116 citations and an h-index of 62. The Middle East, South America, and Africa had significantly fewer publications, with 44, 41, and 5 documents respectively. The Middle East's publications earned 840 citations and an h-index of 15, South America's documents garnered 725 citations and an h-index of 16, and Africa's modest contribution accumulated 61 citations and an h-index of 3.
Conclusion:
Despite the remarkable growth and applications of liquid biopsy, significant regional disparities in research contributions and impacts are evident. Addressing these disparities is crucial for ensuring more equitable advancements and access to liquid biopsy technologies worldwide.
