Summary

This summary is machine-generated.

We developed a new diagnostic tool, ImmunoMetabolic Profiling Analysis and Classification Tool (IMPACT), to predict cisplatin sensitivity in lung adenocarcinoma. This machine learning approach accurately distinguishes between sensitive and resistant tumors using immunometabolic markers.

Background:

Cisplatin resistance is a major challenge in lung adenocarcinoma treatment.
Lack of practical systemic diagnostics for cisplatin sensitivity hinders effective patient stratification.

Purpose of the Study:

To develop and validate an interpretable machine learning pipeline, IMPACT, for predicting cisplatin sensitivity in lung adenocarcinoma.
To identify key immunometabolic features associated with cisplatin sensitivity and resistance.

Main Methods:

Quantified serum amino acids and immune cell populations in a syngeneic orthotopic model.
Utilized recursive feature elimination within IMPACT to identify minimal, mechanistically informative feature sets.
Employed machine learning to classify cisplatin-sensitive vs. cisplatin-resistant tumors and cancer vs. control groups.

Main Results:

IMPACT achieved high accuracy (AUC = 0.950) in classifying cisplatin-sensitive vs. cisplatin-resistant lung adenocarcinoma.
Bone marrow myeloid-derived suppressor cells (MDSCs) and serum glutamine were key predictors of cisplatin sensitivity.
The framework also accurately classified cancer vs. control groups (AUC = 0.955), with lung MDSCs and phosphoserine as top features.

Conclusions:

IMPACT provides a promising, accurate, and interpretable method for assessing cisplatin sensitivity in lung adenocarcinoma.
Systemic immunometabolic profiling, particularly bone marrow MDSCs and serum glutamine, offers valuable insights into platinum-based chemotherapy response.
This approach has potential for clinical application in stratifying lung adenocarcinoma patients for chemotherapy.
