Long-term outcome of definitive radiotherapy for locally advanced non-small cell lung cancer: A real-world single-center study in the pre-durvalumab era.
Article in Cancer medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThere was limited research data on large-scale locally advanced non-small cell lung cancer (LA-NSCLC) radical radiotherapy (RT) reported in China. This study examined overall survival (OS), progression-free survival (PFS), treatment effectiveness, and toxicity in patients with LA-NSCLC treated with definitive RT in the pre-durvalumab era.
methodsA retrospective analysis of demographic information, clinical characteristics, treatment patterns, and clinical outcomes of 789 patients with LA-NSCLC who underwent radical RT at our center between January 2005 and December 2015 was performed. The Kaplan-Meier method and log-rank test were used for survival comparisons, and Cox regression was used for multivariate analysis.
resultsThere were 328 patients with stage IIIA disease and 461 with stage IIIB disease. By the last follow-up, there were 365 overall deaths and 576 cases of recurrence, metastasis, or death. The median survival time was 31 months. The OS rates at 1, 2, 5, and 10 years were 83.7%, 59.5%, 28.8%, and 18.9%, respectively. PFS rates at 1, 2, 5, and 10 years were 48%, 24.5%, 11.9%, and 5.5%, respectively. Rates of ≥grade 3 acute radiation pneumonitis or esophagitis were 7.6% and 1.9%, respectively. Rates of ≥grade 3 chronic radiation pneumonitis and esophagitis were 11% and 0.4%, respectively. Multivariate analysis showed that the Karnofsky Performance Status (KPS) score, smoking status, and combined chemotherapy were prognostic factors for OS (p < 0.05). Multivariate analysis revealed that combined chemotherapy and radiation dose were prognostic factors for PFS (p < 0.05).
conclusionsOur center's data showed that the survival prognosis of locally advanced patients receiving RT and chemotherapy in China was consistent with international levels during the same period. Patients with a KPS score of 80 or higher, who had never smoked or received combined RT, had a more favorable prognosis than those with a KPS of less than 80, who had smoked, or only received RT. The combination of RT and chemotherapy, with a reasonable radiation dose, was the key to improving the therapeutic effect.
