View abstract on PubMed
Summary
This summary is machine-generated.The LIONS PREY scoring system accurately predicts pulmonary malignancy likelihood, outperforming existing models. This tool aids multidisciplinary teams in decision-making for lung nodules.
Area Of Science
- Pulmonology
- Radiology
- Oncology
Background
- Classifying pulmonary lesions as malignant is challenging.
- Existing scoring systems, like the Mayo model, lack precision in malignancy prediction.
- A need exists for a more accurate tool to assess the likelihood of malignancy in pulmonary nodules.
Purpose Of The Study
- To develop and validate a novel logistic scoring system, LIONS PREY (Lung lesION Score PREdicts malignancY), for improved precision in determining the likelihood of pulmonary malignancy.
- To compare the performance of LIONS PREY against existing models, such as the Mayo score.
Main Methods
- A retrospective analysis of patients evaluated by a multidisciplinary team between January 2013 and December 2020.
- Inclusion criteria required pathological results after resection or CT-/EBUS-guided sampling.
- Two groups were formed: malignant nodules (n=238) and benign nodules (n=148). Initially, 22 parameters were assessed, with eight ultimately integrated into the LIONS PREY score after uni- and multivariate analysis.
Main Results
- The LIONS PREY system integrated eight key parameters: age, nodule size, spiculation, solidity, size dynamics, smoking history, pack years, and cancer history.
- The model demonstrated superior precision compared to the Mayo score (p=0.013).
- LIONS PREY achieved an overall correct classification rate of 96.0%, a calibration ratio of 1.1, and an AUC of 0.94 (95% CI: 0.92-0.97).
Conclusions
- LIONS PREY is a precise, easily applicable, and reproducible scoring system for computed tomography (CT) scans.
- The system can facilitate decision-making for multidisciplinary teams and aid patients in consenting to surgery.
- A mobile application for LIONS PREY is available on Android and iOS devices.

Epidemiological data primarily involves information on specific populations' occurrence, distribution, and determinants of health and diseases. This data is crucial for understanding disease patterns and impacts, aiding public health decision-making and disease prevention strategies. The analysis of epidemiological data employs various statistical methods to interpret health-related data effectively. Here are some commonly used methods:

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
