Carbon-ion radiotherapy in the treatment of radiation-induced second primary malignancies.
Article in Annals of translational medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Background: Treatment of radiation-induced second primary malignancy (RI-SPM) is challenging and usually associated with poor outcomes. For patients with unresectable or incompletely resected diseases, carbon-ion radiotherapy (CIRT) offers physical and biologic advantages over photon-based re-irradiation. We report the results of salvage CIRT in 15 patients with RI-SPM. Methods: Fifteen consecutive and non-selected patients with RI-SPM who underwent salvage CIRT at the Shanghai Proton and Heavy Ion Center between November 2015 and May 2019 were included in this retrospective study. CIRT doses were 57.5-69 Gy (RBE) [at 2.5-3.0 Gy (RBE)/daily fraction]. The actuarial 1-year overall survival (OS), locoregional progression-free survival (LPFS), distant metastasis-free survival (DMFS), and progression-free survival (PFS) rates as well as acute/late toxicities were analyzed. Results: Among the 15 patients included, 10 were soft tissue sarcomas, 2 were chondrosarcomas, 1 was osteosarcoma, 1 was squamous cell carcinoma and 1 was esthesioneuroblastoma. With a median follow-up of 13.0 (range, 2.73-29.63) months, the actuarial 1-year OS, LPFS, DMFS, and PFS rates were 69.3%, 53.0%, 92.9%, and 48.2%, respectively. No grade 2 and grade 3 acute adverse effect was observed. One patient experienced grade 4 hemorrhage which required embolization during CIRT, and lately died from hemorrhage (grade 5) at 3.4 months after the completion of CIRT. No other late adverse effects of ≥ grade 2 was observed. Conclusions: Salvage CIRT provided relatively safe and effective short-term outcome for patients with unresectable or in-completely resected RI-SPM, as compared to historical data on re-irradiation using the conventional photon beam technology. However, further improvement in both disease control and toxicity prevention is needed.
