The gefitinib dose reduction on survival outcomes in epidermal growth factor receptor mutant non-small cell lung cancer.
Article in Journal of cancer research and clinical oncology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 3 of them syntheses that pooled 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.
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
purposeGefitinib is safe for the treatment of non-small cell lung cancer (NSCLC), but some patients experience toxicities and require dose reduction. The purpose of this study was to evaluate the effect of gefitinib dose reduction on survival.
methodsWe retrospectively analyzed 263 patients with NSCLC harboring sensitive epidermal growth factor receptor (EGFR) mutation. All patients had recurred or metastatic disease and received gefitinib 250 mg daily as palliative chemotherapy.
resultsOf the 263 patients, 23 had gefitinib dose reduction due to toxicities (1 due to mucositis, 5 due to skin rash, 11 due to hepatotoxicity and 6 for both skin and hepatotoxicity). In the dose reduction group, the mean dose intensity was 0.84 (range 0.48-0.98). Patients with dose reduction showed significantly prolonged progression-free survival (PFS) and overall survival (OS) compared to those receiving the standard dose (median PFS: 14.0 vs. 10.6 months, P = 0.042, median OS: 54.5 vs. 29.6, P = 0.020). In multivariate analysis, the effect of dose reduction was not significantly associated with prolonged PFS [hazard ratio (HR) 0.619, 95 % confidence interval (CI) 0.357-1.073, P = 0.085], or OS (HR 0.625, 95 % CI 0.287-1.362, P = 0.237). However, patients receiving low-dose gefitinib tended to have superior survival outcomes compared to those receiving standard-dose gefitinib.
conclusionsThe patients experiencing gefitinib dose reduction or short-term treatment interruption due to toxicities did not show inferior survival, compared to those receiving full dose of gefitinib in NSCLC patients with EGFR mutation.
