How international indexing is amplifying Chinese cancer research and accelerating global collaboration
For any medical researcher, the moment their completed study is accepted into a prestigious scientific journal represents both an endpoint and a beginning. Months, sometimes years, of meticulous laboratory work, data analysis, and manuscript preparation culminate in this professional achievement.
Publication is only the first step in a paper's journey toward scientific impact. The real measure of its significance often lies in its visibility to the global research community—its ability to be discovered, cited, and built upon by colleagues worldwide.
This is where journal indexing becomes crucial. When a scientific journal becomes indexed in major international databases like Science Citation Index Expanded (SCIE), it transforms from a local publication into a global platform. For Chinese cancer researchers, this international recognition has opened new doors for sharing discoveries that could benefit patients everywhere.
SCIE indexing transforms regional research into globally accessible knowledge, enabling discoveries to reach international audiences.
The Science Citation Index Expanded (SCIE) is a prestigious database managed by Clarivate Analytics that includes the world's leading scientific and technical journals across more than 150 disciplines2 . Contrary to common misconception, there is no longer a distinction between SCI and SCIE—Clarivate officially merged these in January 2020, with all references now consolidated under SCIE2 .
When a journal is accepted into SCIE, it undergoes rigorous evaluation to ensure it meets high standards of quality, originality, and editorial rigor.
Chinese cancer journals that have achieved SCIE indexing, such as the Chinese Journal of Cancer Research (CJCR), provide particularly valuable platforms for research addressing cancer types that disproportionately affect Asian populations1 5 .

To understand how publication in indexed journals helps share critical findings, let's examine a representative study on battling one of oncology's most challenging opponents: pancreatic cancer.
In 2015, Chinese researchers published a groundbreaking study in the Chinese Journal of Cancer Research exploring how a small molecule called microRNA-218 (miR-218) could potentially inhibit pancreatic cancer progression. Their investigation focused on miR-218's ability to target HMGB1, a protein known to promote cancer growth and spread.
The research team designed a series of experiments to methodically test their hypothesis:
| Tool | Function |
|---|---|
| microRNA mimics | Synthetic RNAs mimicking natural miRNAs |
| Flow cytometry | Analyzes cell characteristics |
| Western blotting | Detects specific proteins |
| Cell invasion chambers | Simulates tissue barriers |
| Cell culture systems | Grows cells outside the body |
Targets HMGB1 protein to inhibit pancreatic cancer progression
The findings revealed compelling evidence for miR-218's therapeutic potential. When compared to control groups, pancreatic cancer cells treated with miR-218 showed:
Significantly reduced rates
Lower capability through barriers
More programmed cell death
Substantially reduced protein levels
Statistical analysis confirmed these differences were highly significant (p<0.01), strongly supporting the hypothesis that miR-218 suppresses pancreatic cancer by targeting HMGB1.
| Parameter Measured | Control Group | miR-218 Treated Group | Statistical Significance |
|---|---|---|---|
| Cell proliferation rate | Baseline (100%) | Reduced by ~40% | p<0.01 |
| Invasion capability | Baseline (100%) | Decreased by >50% | p<0.01 |
| Apoptosis rate | Baseline level | Increased by >60% | p<0.01 |
| HMGB1 protein level | Normal expression | Significantly reduced | p<0.01 |
When studies like the miR-218 investigation become accessible through SCIE-indexed journals, their impact extends far beyond the laboratory walls. Other researchers can:
This global knowledge sharing creates a virtuous cycle of discovery that ultimately benefits patients through better diagnostic methods, more targeted therapies, and improved survival rates.
The Chinese Journal of Cancer Research, with its current Impact Factor of 6.3 (2024), exemplifies how regional journals can achieve international relevance1 . By maintaining high standards and global visibility, such platforms ensure that important cancer research—particularly on malignancies prevalent in Asian populations—reaches the broadest possible audience of researchers, clinicians, and patients.
Connecting researchers across continents
Researchers
Clinicians
Patients
The indexing of Chinese cancer journals in SCIE represents more than an academic achievement—it signifies China's growing integration into the global biomedical research community. This collaboration accelerates progress against cancer everywhere, as discoveries made in Beijing laboratories might inspire innovations in Boston hospitals, and clinical observations from Shanghai could inform prevention strategies in São Paulo.
For patients and their families, this scientific connectivity translates to hope—the hope that researchers worldwide are working together, sharing insights, and moving closer to better treatments and eventual cures. As these international channels of communication remain open and expand, we all benefit from the collective wisdom of the global scientific community in its shared mission to conquer cancer.
