Haematological and nutritional prognostic biomarkers for patients receiving CROSS or FLOT.
Article in Journal of gastrointestinal oncology, 2023. 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
Background: Neoadjuvant carboplatin and paclitaxel with radiotherapy (CROSS) and perioperative docetaxel, oxaliplatin, calcium folinate and fluorouracil (FLOT) are widely used for gastric (GC), gastro-oesophageal junction (GOJ) and oesophageal cancers (OC). Prognostic and predictive markers for response and survival outcomes are lacking. This study evaluates dynamic neutrophil-lymphocyte ratios (NLR), platelet-lymphocyte ratios (PLR), albumin and body mass index (BMI) as predictors of survival, response and toxicity. Methods: This multi-centre retrospective observational study across 5 Sydney hospitals included patients receiving CROSS or FLOT from 2015 to 2021. Haematological results and BMI were recorded at baseline and pre-operatively, and after adjuvant treatment for FLOT. Toxicities were also recorded. An NLR ≥2 and PLR ≥200 was used to stratify patients. Univariate and multivariate analyses were performed to determine predictors of overall survival (OS), disease free survival (DFS), rates of pathological complete response (pCR) and toxicity. Results: One hundred sixty-eight patients were included (95 FLOT, 73 FLOT). A baseline NLR ≥2 was predictive for worse DFS (HR 2.78, 95% CI: 1.41-5.50, P<0.01) and OS (HR 2.90, 95% CI: 1.48-5.67, P<0.01). Sustained elevation in NLR was predictive for DFS (HR 1.54, 95% CI: 1.08-2.17, P=0.01) and OS (HR 1.65, 95% CI: 1.17-2.33, P<0.01). An NLR ≥2 correlated with worse pCR rates (16% for NLR ≥2, 48% for NLR <2, P=0.04). A baseline serum albumin <33 was predictive of worse DFS and OS with a HR of 6.17 (P=0.01) and 4.66 (P=0.01) respectively. Baseline PLR, BMI, and dynamic changes in these markers were not associated with DFS, OS or pCR rates. There was no association of the aforementioned variables with toxicity. Conclusions: This demonstrates that a high inflammatory state represented by an NLR ≥2, both at baseline and sustained, is prognostic and predictive of response in patients receiving FLOT or CROSS. Baseline hypoalbuminaemia is predictive of poorer outcomes.
