A comparative study of ProGRP and CEA as serological markers in small cell lung cancer treatment.

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
backgroundSmall Cell Lung Cancer (SCLC) presents a significant clinical challenge due to its aggressive nature and the need for effective biomarkers for treatment monitoring. This study aimed to compare ProGRP and CEA as serological markers in the monitoring of SCLC treatment.
methodsWe retrospectively analyzed data from 80 SCLC patients and 80 matched controls. ProGRP and CEA levels were measured, and their associations with clinical parameters, including tumor stage and treatment response, were assessed using Spearman's rank correlation coefficient. Multivariate logistic regression models were employed to identify independent predictors of treatment response and disease progression.
resultsProGRP and CEA levels were considerably higher in cases than controls, with median ProGRP levels at 198.5 pg/mL versus 48.7 pg/mL and median CEA levels at 5.2 ng/mL versus 2.9 ng/mL (both p < 0.001). ProGRP levels correlated positively with tumor stage (ρ = 0.58, p < 0.001) and negatively with treatment response (ρ = - 0.45, p = 0.001). CEA levels also showed positive correlation with tumor stage (ρ = 0.48, p = 0.002) and negative correlation with treatment response (ρ = - 0.35, p = 0.005). Multivariate analysis revealed that ProGRP was an independent predictor for treatment response (OR 1.25 per 100 pg/mL increase, p = 0.001) and disease progression (OR 1.25 per 50 pg/mL increase, p = 0.012), while CEA was a marginal predictor for treatment response (OR 0.95 per 1 ng/mL increase, p = 0.045).
conclusionBoth ProGRP and CEA are significant serological markers in SCLC patients, with ProGRP showing a stronger correlation with tumor stage and treatment response. ProGRP may serve as a superior independent predictor of treatment response and disease progression compared to CEA. These findings support the incorporation of ProGRP in SCLC treatment monitoring protocols.
