JAMA Oncology had a very active year in 2019. The journal’s impact factor of 22.4 places it as one of the highest-ranking oncology journals. I thank our authors, peer reviewers, and readers for the significant contributions made to the journal this past year. The editorial board, our JAMA Oncology editors, and I are honored to have the opportunity to serve the oncology community by offering original, innovative, and timely scientific content that has a direct impact on researchers, clinicians, and the patients we serve.

Choosing manuscripts for the journal was rewarding but challenging. We received a total of 2980 manuscript submissions in 2019. These submissions to JAMA Oncology included 1743 Original Investigations, 66 Clinical Trial reports, 66 Meta-analyses, and 70 Reviews. In 2019, we published 419 total articles, including 119 Original Investigations, 31 Research Letters, 32 Viewpoints, 10 Reviews, and 5 Special Communications. I thank our authors for choosing JAMA Oncology. The quality of their articles is reflected in the more than 2.6 million views and downloads of JAMA Oncology articles last year.

In 2019, the overall acceptance rate was 13%. Our acceptance rate was 6% for Original Investigations, 35% for Clinical Trials reports, and 39% for Meta-analyses. We accepted 13% of Review articles, 11% of submitted Research Letters, 30% of Viewpoints, and 16% of Clinical Challenges. JAMA Oncology is indexed in PubMed/MEDLINE, Science Citation Index Expanded, Scopus, and other databases. More detailed statistics about our content are displayed in the Table.^1-3
