Patterns of Relapse and Implications for Post-Nephrectomy Surveillance in Patients with High Risk Nonclear Cell Renal Cell Carcinoma: Subgroup Analysis of the Phase 3 ECOG-ACRIN E2805 Trial.
Article in The Journal of urology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeThe natural history of nonclear cell renal cell carcinoma following surgery with curative intent remains poorly defined with postoperative surveillance informed by guidelines largely intended for clear cell renal cell carcinoma. We evaluated relapse patterns and potential implications for post-nephrectomy surveillance in patients with nonclear cell renal cell carcinoma enrolled in the E2805 trial, the largest randomized trial of adjuvant antiangiogenic therapy of high risk renal cell carcinoma. MATERIALS AND
methodsWe retrospectively analyzed the records of patients with completely resected nonclear cell renal cell carcinoma. Participants received up to 54 weeks of postoperative therapy with sunitinib, sorafenib or placebo and underwent surveillance imaging at standardized intervals for 10 years. For recurrence rates by site the cumulative incidence was estimated, accounting for competing risks. The adequacy of strict adherence to post-nephrectomy surveillance guidelines was evaluated.
resultsA total of 403 patients with nonclear cell renal cell carcinoma were enrolled in the study. During a median followup of 6.2 years 36% of nonclear cell renal cell carcinomas recurred. Five-year recurrence rates were comparable for nonclear and clear cell renal cell carcinoma in the 1,541 patients, including 34.6% (95% CI 29.8-39.4) and 39.5% (95% CI 36.9-42.1), respectively. However, patients with nonclear cell renal cell carcinoma were significantly more likely to have abdominal sites of relapse (5-year recurrence rate 26.4% vs 18.2%, p = 0.0008) and significantly less likely to experience relapse in the chest (5-year recurrence rate 13.7% vs 20.9%, p = 0.0005). Current surveillance guidelines would potentially capture approximately 90% of relapses at any site.
conclusionsNonclear cell renal cell carcinoma may show a distinct pattern of relapse compared to clear cell renal cell carcinoma. Our findings emphasize the importance of cross-sectional, long-term imaging in patients with high risk, resected, nonclear cell renal cell carcinoma.
