Feasibility and prognostic benefit of induction chemoradiotherapy followed by surgery in patients with locally advanced non-small cell lung cancer.
Article in Journal of thoracic disease, 2020. 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
backgroundThe optimal treatment for patients with resectable non-small cell lung cancer (NSCLC) involving adjacent organs (T3 or T4) and/or cN2 remains unclear. We investigated whether or not induction chemoradiotherapy (ICRT) followed by surgery improves the survival.
methodsWe retrospectively analyzed 84 patients with NSCLC involving the adjacent organs and/or cN2 who underwent ICRT followed by surgery at our hospital from 2006 to 2018. Presurgical treatment consisted of 2 courses of platinum-doublet and concurrent radiotherapy (40-50 Gy) to the tumor and involved field.
resultsAll 84 patients completed ICRT. One patient died after completion of ICRT due to bacterial pneumonia. Radiological responses to ICRT were a complete response (CR), n=1; partial response (PR), n=48; stable disease (SD), n=32; and progressive disease (PD), n=2 (overall response rate: 58.3%). Eighty-one patients underwent radical surgery. The procedures included lobectomy, n=66; bilobectomy, n=7; pneumonectomy, n=6; and segmentectomy, n=2 (including 49 extended resections). Seventy-three patients (90%) underwent complete resection. The postoperative morbidity rate was 30%. The 30- and 90-day mortality rates were 1.2% and 2.4%, respectively. A pathological CR (Ef3) and major response (Ef2) were achieved in 17 (21.0%) and 38 (46.9%) patients, respectively; a minor response (Ef1) was observed in 26 (32%). The 5-year overall survival (OS) and recurrence-free survival (RFS) rates were 58.0% and 45.6%, respectively. The median survival time was 73.2 months. Based on the response to ICRT, patients with radiological CR or PR showed better 5-year OS than those with SD (63.7%
conclusionsICRT followed by surgery for patients with NSCLC involving the adjacent organs and/or cN2 was feasible and improved the survival. A CR/PR or Ef2/Ef3 after ICRT led to a better prognosis.
