Phase I study of daily S-1 combined with weekly irinotecan in patients with advanced non-small cell lung cancer.
Article in International journal of clinical oncology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundS-1 is a novel oral fluorouracil prodrug active against non-small cell lung cancer (NSCLC). To determine the feasibility of S-1 combined with weekly irinotecan for patients with advanced NSCLC, we performed a phase I study to determine the maximum tolerated dose (MTD) and the recommended dose (RD) of irinotecan.
methodsPatients with advanced NSCLC received S-1 (80 mg/m(2)) on days 1-14 and irinotecan (50-80 mg/m(2)) on days 1, 8, and 15 of each 28-day cycle. Three to six patients were treated with each dose of irinotecan, with the MTD defined as the dose at which dose-limiting toxicity (DLT) appeared in 33% of patients.
resultsAt doses of 50-70 mg/m(2), no patients experienced any DLT, whereas, at a dose of 80 mg/m(2), two of four patients experienced DLTs. Two patients experienced grade 3 toxicities - neutropenia and diarrhea.
conclusionThe MTD of weekly irinotecan was 80 mg/m(2), making its RD for phase II trials 70 mg/m(2).
