Relapse detection in the Danish surveillance program of patients with clinical stage I seminoma: a nationwide study.

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 purposeActive surveillance is a recommended management strategy for patients with clinical stage I (CSI) seminoma. This study aims to identify patterns of relapse detection methods in an unselected population-based cohort of CSI patients and provide evidence for a risk-adapted follow-up program. PATIENTS/MATERIALS AND
methodsA total of 924 patients with CSI seminoma were identified in the prospective Danish Testicular Cancer database. Retrospectively collected clinical data were used for descriptive analyses of patterns in detection methods. Additionally, we explored a risk-adapted surveillance approach based on recently identified risk factors for relapse, classifying patients into low- and non-low-risk groups.
resultsAt 60 months, the 5-year cumulative relapse risk was 16%, with 146 relapses during surveillance. Relapses were detected by imaging alone in 71% of cases, imaging combined with elevated serum tumor markers (STMs) in 18%, isolated elevation of STMs in 8%, and by self-referral due to symptoms in 3%. No relapses were detected by abnormal findings at a physical examination. In total, 134 (92%) relapses were localized to retroperitoneal lymph nodes, primarily without additional spread. The 5-year relapse risk in patients with low risk of relapse was 9% compared to 28% in patients in the non-low-risk group.
interpretationThis study highlights that the surveillance program can detect relapses at an early stage. Reduction of visits and omission of routine physical examinations can safely be considered for patients with a low risk of relapse, while further research is needed to optimize follow-up and treatment for patients at higher risk of relapse.
