Characterization of renal injury in non-squamous non-small cell lung cancer patients treated with pemetrexed: A single-center retrospective study.
Article in Thoracic cancer, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionPemetrexed is a key therapeutic agent for advanced non-squamous non-small cell lung cancer (Nsq-NSCLC), yet it is associated with renal toxicity. This study aims to elucidate the incidence, risk factors, and survival impact of renal injury in patients with Nsq-NSCLC treated with pemetrexed.
methodsWe conducted a retrospective study including 136 patients with Nsq-NSCLC treated with pemetrexed. Data on demographics, renal function, progression-free survival (PFS), and overall survival (OS) were collected. Renal injury was defined as a reduction above 25% in estimated glomerular filtration rate (eGFR) from baseline. Its associated risk factors were analyzed using logistic regression, and impact on survival was analyzed using log-rank test. The creatinine clearance rate (CCr) was calculated, and a CCr < 45 mL/min served as a contraindication for continuing pemetrexed.
resultsThe study found a 31.6% (43/136) incidence of renal injury, with 9.6% (13/136) having CCr < 45 mL/min and discontinuing pemetrexed. Univariate and multivariate analyses identified factors significantly associated with increased renal injury risk including older age, use of cisplatin, and higher number of pemetrexed cycles. The patients with renal injury had a median PFS (mPFS) of 13.5 months and a median OS (mOS) of 36.0 months, while the patients without had an mPFS of 9.0 months and an mOS of 35.0 months, and these differences were not statistically significant.
conclusionRenal injury is a considerable complication in patients with Nsq-NSCLC undergoing pemetrexed treatment, with age, platinum type, and pemetrexed treatment cycles as key risk factors. These findings highlight the necessity for careful renal monitoring in this patient population.
