Outcome appraisal of patients with limited brain metastases (BMs) from non small cell lung cancer (NSCLC) treated with different local therapeutic strategies: a single institute evaluation.
Article in The British journal of radiology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
objectiveTo evaluate the outcome of patients with non-small-cell lung cancer (NSCLC) with limited brain metastases (BMs) treated with local approaches omitting whole-brain radiation therapy (WBRT).
methodsSurgery was performed in case of a single, large BM, controlled extracranial disease and Karnofsky Performance Status (KPS) 90-100; stereotactic radiosurgery (SRS) or hypofractionated stereotactic radiosurgery (HSRS) was performed in all other cases. The prescribed dose was 24 Gy/1 fraction for lesions <2.5 cm, and a median of 30 Gy (24-40 Gy) in 3-5 fractions for lesions >2.5 cm.
results156 patients treated for 228 BMs were retrospectively evaluated. The median age was 62 years. The majority of patients had a KPS 90-100, recursive partitioning analysis Class II, diagnosis-specific graded prognostic assessment score 2.5-3 and 1-2 BMs. Surgical resection was performed in 18 cases, and SRS/HSRS was performed in 210 cases. The 1-2-year local control was 87.2 ± 3.0% and 72.8 ± 5.0%; the 1.2-year brain distant failure was 30.8 ± 4.0% and 58.1 ± 6.0%; the 1-2-year overall survival was 60.9 ± 3.9% and 31.4 ± 4.0%. On univariate and multivariate analysis, the following factors influenced survival: age (p = 0.01), the presence of lymph node involvement (p = 0.03), KPS (p << 0.01), the presence of extracranial metastases at the time of BM treatment (p < 0.01), the number of BMs (p = 0.02) and the treatment performed (p < 0.01).
conclusionThe choice of an adequate local treatment can impact on survival in patients with limited BMs from NSCLC. A careful evaluation of prognostic and predictive factors is a pivotal additional aid. Advances in knowledge: Radiosurgery or surgery followed by radiosurgery on the tumour bed in place of WBRT proved to be an effective treatment influencing outcome. Surgical resection followed by SRS on the tumour bed has to be considered for lesions ≥15 mm, in patients with good KPS, age ≤70 years, adenocarcinoma histology and oligometastatic disease.
