Conditional recurrence-free survival after curative esophagectomy: individual patient data analysis of 11 trials.
Article in Journal of the National Cancer Institute, 2026. 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
backgroundMost recurrences after curative surgery for esophageal cancer occur within 2 years. Conventional recurrence-free survival (RFS), calculated from the time of surgery, may underestimate prognosis for patients who remain recurrence-free during the early postoperative years. This study aimed to evaluate conditional RFS and recurrence timing to inform individualized follow-up strategies.
methodsAn individual patient data (IPD) analysis was conducted using randomized controlled trials (RCTs) comparing perioperative treatments for resectable esophageal or gastroesophageal junction cancer. Conditional RFS, defined as the probability of remaining recurrence-free for an additional y years given x years already survived without recurrence (RFSy|RFSx), was estimated.
resultsIPD from 10 phase III and 1 phase II RCTs were analyzed (n = 2268 patients with R0 resection). In squamous cell carcinoma (SCC), RFS5|RFS0 was 47.9%, which increased to 63.0%, 72.5%, 78.2%, and 81.2% at RFS5|RFS1-4. Among patients who recurred, 58.8% of pN-positive cases recurred within 1 year and 81.7% within 2 years, compared with 42.8% and 69.9% in pN0. At baseline (RFS5|RFS0), patients with pN-positive disease or pM1 disease had worse 5-year RFS than those with pN0 or pM0 disease. However, among patients who remained recurrence-free for 4 years after surgery (RFS5|RFS4), the pattern was reversed, with advanced groups showing better subsequent 5-year RFS. Similar trends were observed in adenocarcinoma.
conclusionsConditional RFS improves over time, particularly in advanced-stage esophageal cancer. Although advanced cases are typically monitored more intensively, findings suggest comparable follow-up intensity may be appropriate once patients remain recurrence-free for a certain postoperative period.
