1 · What the graph read from 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.

2 · The registry

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

purposeTo retrospectively assess toxicity and outcome of re-irradiation with stereotactic body radiation therapy (SBRT) in patients with recurrent or persistent non-small cell lung cancer (NSCLC), who were previously treated with radical radiation therapy (50-60 Gy). The secondary endpoint was to investigate whether there are dosimetric parameter predictors of severe radiation toxicity. METHODS AND MATERIALS: The analysis was conducted in 17 patients with "in-field" recurrent/persistent centrally located NSCLC, who underwent re-irradiation with SBRT. SBRT consisted of 30 Gy in 5 to 6 fractions; these prescriptions would be equivalent for the tumor to 37.5 to 40 Gy, bringing the total 2-Gy-per-fraction cumulative dose to 87 to 100 Gy, considering the primary radiation therapy treatment. Actuarial analyses and survival were calculated by the Kaplan-Meier method, and P values were estimated by the log-rank test, starting from the date of completion of SBRT. Dosimetric parameters from the subgroups with and without grade ≥3 pulmonary toxicity were compared using a 2-tailed Student t test.

resultsThe median follow-up was 18 months (range, 4-57 months). Only 2 patients had local failure, corresponding to a local control rate of 86% at 1 year. The Kaplan-Meier estimates of overall survival (OS) rates at 1 and 2 years were 59% and 29%, respectively; the median OS was 19 months. Four patients (23%) experienced grade 3 radiation pneumonitis, and 1 patient developed fatal pneumonitis. One patient died of fatal hemoptysis 2 months after the completion of SBRT. Unexpectedly, heart maximum dose, D5 (minimum dose to at least 5% of the heart volume), and D10 were correlated with risk of radiation pneumonitis (P<.05).

conclusionsRe-irradiation with SBRT for recurrent/persistent centrally located NSCLC achieves excellent results in terms of local control. However, the high rate of severe toxicity reported in our study is of concern.
