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

backgroundSurvival in patients with urothelial cancer (UC) recurrence after initial treatment with curative intent is limited and treatment options are sparse. Metastasectomy could be considered a treatment option in selected cases. Identifying prognostic factors for survival can be used to counsel patients and aid multidisciplinary teams in making treatment decisions.

methodsWe collected a retrospective case series of patients undergoing metastasectomy for oligometastatic UC between 1999 and 2018 at University Hospitals Leuven. Oligometastatic UC was defined as recurrence of UC in a single organ with ≤3 metastases. Survival outcomes of interest were: overall survival (OS), cancer-specific survival (CSS), and secondary recurrence-free survival (RFS2). Complications were reported using the Clavien-Dindo classification (CDC). Survival analysis are descriptive and were performed using Kaplan-Meier plots to visualize survival data and log-rank was used to compare survival between groups.

resultsFrom 1999 to 2018, a total of 22 patients underwent metastasectomy of oligometastatic UC. Metastasectomy sites were: pulmonary (59.1%), loco-regional (13.6%), hepatic (9.1%), adrenal (4.5%), testicular (4.5%), nodal above aortic bifurcation (4.5%), and renal transplant (4.5%). The 5-year OS, CSS and RFS2 after metastasectomy were 51.4%, 57.0%, and 49.9%, respectively. Patients with primary upper tract urothelial cancer (UTUC) involvement and patients treated with hepatic metastasectomy had a significantly worse OS, CSS, and RFS2. Patients with a lesion size >8 mm and patients with >1 pulmonary lesion had a significantly worse CSS. Two CDC grade 3B occurred during follow-up and were both non-procedure related.

conclusionsMetastasectomy of oligometastatic UC is feasible and can achieve durable cancer control in a highly selected subgroup of patients. Our results suggest that patients with hepatic metastases or primary UTUC involvement could be considered poor candidates for metastasectomy, while patients with a small (<8 mm) or solitary pulmonary lesion might benefit most. These findings should be validated in multi-institutional collaborations or prospective clinical studies.
