Neoadjuvant chemoradiotherapy followed by resection for esophageal cancer: clinical outcomes with the 'CROSS-regimen' in daily practice.
Article in Diseases of the esophagus : official journal of the International Society for Diseases of the Esophagus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
BACKGROUND AND
objectivesSince the first results of the Dutch randomized CROSS-trial, neoadjuvant chemoradiotherapy (CRT) using carboplatin and paclitaxel followed by resection for primary resectable nonmetastatic esophageal cancer (EC) has been implemented as standard curative treatment in the Netherlands. The purpose of this retrospective study is to evaluate the clinical outcomes of this treatment in daily practice in a large academic hospital.
methodsMedical records of patients treated for primary resectable nonmetastatic EC between May 2010 and December 2015 at our institution were reviewed. Treatment consisted of five weekly courses of carboplatin (area under the curve 2) and paclitaxel (50 mg/m2) with concurrent external beam radiotherapy (23 fractions of 1.8 Gy), followed by transthoracic or transhiatal resection. Data on survival, progression, acute and late toxicity were recorded.
resultsA total of 145 patients were included. Median follow-up was 43 months. Median overall survival (OS) and progression-free survival (PFS) were 35 (95% confidence interval [CI] 29.8-40.2) and 30 (95% CI 19.7-40.3) months, respectively, with corresponding 3-year OS and PFS of 49.6% (95% CI 40.4-58.8) and 45.6% (95% CI 36.6-54.6). Acute toxicity grade ≥3 was observed in 25.5% of patients. Late adverse events grade ≥3 were seen in 24.8%, mostly esophageal stenosis.
conclusionNeoadjuvant CRT followed by resection for primary resectable nonmetastatic EC in daily practice results in a 3-year OS of 49.6% (95% CI 40.4-58.8) and PFS of 45.6% (95% CI 36.6-54.6), compared with 58% (51-65%) and 51% (43-58%) within the CROSS-trial. The slightly poorer survival in our daily practice group might be due to the presence of less favorable patient and tumor characteristics in daily practice, as is to be expected in daily practice. Toxicity was comparable with that in the CROSS-trial and considered acceptable.
