ASTRO's Advances in Radiation Oncology’s Top Twenty Downloads for 2021

Our year in publishing at ASTRO's Advances in Radiation Oncology in 2020 was focused sharply on the response to the pandemic. Although the pandemic continued through 2021, our readers have been interested in a more diverse range of topics more recently, as evidenced by our top 20 downloads for the previous year.

Unlike 2020, there was no single overriding theme to last year's articles that readers saved the most. The most downloaded article was focused on a difficult topic, that of reirradiation in breast cancer for local and regional recurrences. This Mayo Clinic study found that “Reirradiation for locoregional recurrent breast cancer is feasible with acceptable rates of toxicity. Disease control and survival are promising among curative intent reirradiation patients without gross disease.”¹ Breast cancer was a common topic for our most popular downloads, accounting for four of the top twenty most popular articles.

The second most downloaded article, is a case report describing an unusual adverse event after placement of an injectable, biodegradable spacers.² The third most popular was also focused on long term complications of prostate cancer radiotherapy relating to dose escalation and hip injury.³

Coming in fourth is another article focused on reirradiation presented by an international expert panel who developed a consensus statement detailing best practices for the evaluation and treatment of patients with recurrent non-small lung cancer.⁴ In fifth place, is a review article summarizing work in an increasingly popular topic, mobile health applications designed to collect and monitor patient reported outcomes.⁵

The remaining fifteen articles contain a variety of topics, and I would encourage our readers who have not seen them to download. Advances continues to gain readers and increase its impact on the scientific world. Using the CiteScore metric, similar but not identical to an Impact Factor Score, Advances has a score of 3.8. However, the CiteScore Tracker anticipates that growing to 4.2 this year. We anticipate receiving a traditional Impact Factor score later this year.
