Clinical outcome and prognostic survival factors in patients with advanced renal cell carcinoma treated with very low-dose interleukin-2, interferon-alpha, and tegafur-uracil: a single-institution experience.

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
backgroundThe objective of the current study was to determine the efficacy and safety of very low-dose interleukin-2 (IL-2), interferon (IFN)-alpha, and tegafur-uracil for patients with unresectable renal cell carcinoma (RCC), metastatic RCC, or both. Clinical prognostic factors were also investigated.
methodsFifty consecutive patients underwent a 3-week treatment cycle of IL-2 (0.7 x 10(6) Japanese reference units [JRU])/person on days 1-3 weekly), IFN-alpha (3 x 10(6) international units/person, on days 1-5 weekly), and tegafururacil (300 mg/person daily).
resultsThe median follow-up after treatment initiation was 11.3 months. A median of three (range, 1-20) treatment cycles was administered. Of 47 eligible patients, 4 had a treatment response (3 complete responses and 1 partial response; objective response rate, 8.5%). The median progression-free and overall survivals were 8.3 months (95% confidence interval [CI], 5.5-10.9 months) and 38.8 months (95% CI, 27.8-49.7 months), respectively. Only 8 patients had grade III/IV toxicities. Two parameters, i.e., the absence of a previous nephrectomy and a low hemoglobin level, were identified as independent factors predictive of poor survival. Patients with low or intermediate risk (presence of none or one of the two prognostic factors) had a durable median survival exceeding 30 months. High-risk patients with both risk factors had rapid disease progression despite treatment.
conclusionWhile the effectiveness of this immunochemotherapy resulted in a limited antitumor response, low-and intermediate-risk patients with metastatic RCC seemed likely to have a survival benefit. Patient selection is essential to enhance treatment efficiency and avoid useless treatment for high-risk patients.
