Recent trends in radiotherapy use for major cancers in Korea.
Article in Japanese journal of clinical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAlthough the trend in radiotherapy in all cancer patients has been studied, changes in radiotherapy modalities for specific cancer types have not been reported. This study aimed to analyze radiotherapy patterns for major cancers in Korea in recent years. MATERIALS AND
methodsWe collected data from claims and reimbursement records of the Health and Insurance Review and Assessment Service from 2017 to 2020, according to initial diagnostic codes. The radiotherapy modalities for major cancers, such as lung, stomach, colorectal, breast and liver cancer, were analyzed. The radiotherapy modalities consisted of two-dimensional radiotherapy, three-dimensional conformal radiotherapy, intensity-modulated radiotherapy, proton radiotherapy and stereotactic body radiotherapy.
resultsOverall, from 2017 to 2020, the use of two-dimensional radiotherapy and three-dimensional conformal radiotherapy decreased, and intensity-modulated radiotherapy increased. In 2017, three-dimensional conformal radiotherapy accounted for approximately half of the radiotherapy in patients for lung and colorectal cancer, which was replaced by intensity-modulated radiotherapy in 2020. In 2020, stereotactic body radiotherapy also accounted for a large proportion of radiotherapy used in liver cancer cases. Intensity-modulated radiotherapy was most used, followed by three-dimensional conformal radiotherapy and two-dimensional radiotherapy for breast cancer in 2020. Among major cancers, radiotherapy utilization for breast cancer is the highest. Compared with other cancers, the number of patients receiving radiotherapy for stomach cancer was low.
conclusionThe number of patients receiving radiotherapy for major cancers has increased. The use of advanced forms of radiotherapy, such as intensity-modulated radiotherapy, is rapidly increasing for major cancers. The rate of radiotherapy utilization was higher in major cancer patients than in all cancer patients.
