History: Founded in 2004. Known for authoritative content that bridges clinical trials, molecular pathways, and treatment paradigms.
How to Get Published: Mostly invited content. Review proposals must demonstrate exceptional breadth and authoritative expertise.
6. The New England Journal of Medicine (NEJM)
Impact Factor: ~78
Why in the Top 10: NEJM publishes clinical research that directly alters medical practice. Its trials often become the foundation of treatment guidelines. The journal is known for rigorous standards and for selecting studies with immediate relevance to patient care.
History: NEJM was founded in 1812. It became the leading clinical journal by publishing landmark advances in anesthesia, antibiotics, chemotherapy, cardiology, and immunotherapy. Its long history of practice-defining research gives it unmatched authority in medicine.
How to Get Published: Acceptance is about five percent. Studies must show a clear improvement in diagnosis, treatment, or outcomes. The editorial and statistical reviews are strict. Only work with strong methodology and major clinical or public health significance is considered.
7. Annals of Oncology
Impact Factor: ~65
Why in the Top 10: The journal publishes influential clinical research in cancer medicine. Its trials, meta analyses, and consensus papers guide treatment decisions across solid tumors and hematologic malignancies.
History: Annals of Oncology was founded in 1990 as the official journal of the European Society for Medical Oncology. It gained prominence by prioritizing high-quality clinical evidence and by publishing early work on targeted therapies and immunotherapies.
How to Get Published: The journal focuses on studies with direct value for oncologists. Trials, large observational datasets, and authoritative reviews have the strongest chance. The selection process is competitive and requires clear methodology and meaningful implications for cancer care.
8. Nature Reviews Immunology
Impact Factor: ~61
Why in the Top 10: It dominates the immunology field with in-depth reviews that influence both basic science and clinical immunology.
History: Launched in 2001. Quickly became the most cited immunology journal due to its combination of rigorous scholarship and mechanistic depth.
How to Get Published: Primarily invitation-based. Submitted proposals must add substantial value to the field and synthesize rapidly evolving knowledge.
9. Nature Reviews Disease Primers
Impact Factor: ~61
Why in the Top 10: Each Primer provides a comprehensive tutorial on a disease area, often becoming the most authoritative single source on that condition.
History: Started in 2015. Its unique format and depth led to rapid uptake and extreme citation rates.
How to Get Published: Nearly all content is commissioned. Proposals must cover major disease areas with broad global relevance.
10. Nature Medicine
Impact Factor: ~50
