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

objectivesCurative intent therapy of stage II NSCLC may include surgical resection or definitive radiotherapy. Primary management with surgery or radiotherapy may be influenced by patient and disease characteristics. We sought to perform a comparison of patients receiving surgery or radical radiation therapy as their curative treatment, and explore the impact of known prognostic factors on outcome. MATERIALS AND

methodsA retrospective review was completed of all patients with stage II NSCLC referred to the BC Cancer Agency from 2005 to 2012. Cases were filtered to identify those receiving curative intent therapy including surgery or radiotherapy. Information was collected on known prognostic and predictive factors. The primary outcome measure was overall survival. We compared survival among patients receiving curative intent radiotherapy versus surgical intervention.

resultsA total of 535 patients were referred. Of these, 245 (46%) received curative intent surgery, 132 (25%) curative intent radiotherapy, and 158 (30%) did not receive curative therapy. There were significant differences between cohorts with respect to median age, histology, ECOG PS, smoking status, and weight loss. Median OS was significantly different between cohorts: 61.4 m surgery, 26.5 m curative RT, and 13.1 m non-curative therapy. In a case-matched analysis, median OS remained superior for surgery at 101.6 m vs 28.1 m for curative RT. In a multivariate analysis, ECOG PS, weight loss, and treatment cohort all influenced survival. Among patients receiving curative intent radiotherapy, the use of concurrent chemotherapy and RT dose > = 60Gy were associated with improved outcomes.

conclusionsAmong patients with stage II NSCLC, many are unable to undergo standard of care surgical resection. Radiotherapy provides an inferior yet still curative option in the management of inoperable patients. Further work is needed to optimize outcomes in this population.
