Combined neoadjuvant and adjuvant therapy versus adjuvant therapy in high-risk upper tract urothelial carcinoma: a propensity matched multicenter analysis (ROBUUST 2.0 International Collaborative Group).

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
introductionThe efficacy of combined neoadjuvant and adjuvant therapy (CNAT) in upper tract urothelial carcinoma (UTUC) remains unclear despite its demonstrated potential in bladder urothelial carcinoma. High-risk features- clinical stage ≥ T3, node-positive disease, multifocality, high-grade pathology, hydronephrosis, and large tumor size - are associated with poor prognosis in UTUC. We investigated the oncological outcomes of CNAT versus adjuvant therapy (AT) alone in high-risk UTUC patients. MATERIALS AND
methodsWe analyzed perioperative data from 2433 patients with UTUC (2015-2023) across 17 centers in the US, Europe, and Asia. Propensity score matching was performed using preoperative clinical T and N stages. Kaplan-Meier curves and Cox proportional hazards models were used to evaluate overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS), and metastasis-free survival (MFS).
resultsAmong 285 high-risk UTUC patients, 76 matched patients (38 CNAT, 38 AT) were analyzed after matching, with a median follow-up of 15 months. CNAT and AT groups had comparable oncological outcomes: 2-year OS (72.9% vs. 71.8%; p = 0.89), CSS (76.7% vs. 75.3%; p = 0.92), RFS (30.1% vs. 39%; p = 0.97), or MFS (45.5% vs. 44.7%; p = 0.91), respectively. Cox regression showed no significant survival benefit of CNAT over AT after adjusting for clinical and pathological factors (HR for OS: 1.06; p = 0.9).
conclusionIn this large multicenter international cohort, our findings suggest that CNAT does not provide a clear advantage over AT alone in patients with high-risk UTUC. Prospective randomized trials are needed to clarify the role of multimodal therapy in UTUC management.
