Using deep learning to identify tumor origins from lymph node samples

A Multicenter Study on Predicting Tumor Origin Based on Deep Learning of Lymph Node Puncture Cytology

West China Hospital · NCT06810349

This study is trying to see if a new computer program can help find out where tumors that spread to lymph nodes come from, and how it compares to the work of human doctors.

What this trial studies

This study aims to develop a deep learning model that analyzes cytological images from lymph node punctures to predict the origins of tumors that have metastasized to lymph nodes. The model will be constructed using data collected from patients at West China Hospital and will be validated with a large test set to assess its performance. Additionally, the study will compare the accuracy of the deep learning model against human pathologists in diagnosing these cytology smears.

Who should consider this trial

Good fit: Ideal candidates for this study are patients with lymph node metastases and unknown primary tumor origins who have provided relevant clinical data.

Not a fit: Patients with known primary tumor origins or those not undergoing lymph node puncture procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more accurate and timely identification of tumor origins, improving treatment decisions for patients with unknown primary tumors.

How similar studies have performed: While the use of deep learning in medical diagnostics is gaining traction, this specific application in predicting tumor origins from lymph node cytology is relatively novel and has not been extensively tested.
