RadNLP 2024 main task: Document Classification for Lung Cancer Staging
📚 Introduction
RadNLP 2024 is a shared task in the international conference NTCIR-18, organized by the National Institute of Informatics in Japan.
Management of lung cancer is based on the stage, and radiology reports provide various related information by describing medical images such as CT and MRI.
However, radiology reports do not always specify the stage explicitly¹. This imposes extra workload on human experts for careful manual information extraction, which can be aided by automation.
Main task is a multi-label document classification to correctly determine T, N, and M categories for each radiology report.
- T category - Assessment of the size and/or extension of the primary lesion. Available choices: T0, Tis, T1mi, T1a, T1b, T1c, T2a, T2b, T3, T4
- N category - Assessment of the extent of lymph node metastasis. Available choices: N0, N1, N2, N3
- M category - Assessment of the extent of distant metastasis. Available choices: M0, M1a, M1b, M1c
In RadNLP 2024, we follow the staging criteria by the Japan Lung Cancer Society (JLCS). Note that the JLCS criteria closely aligns the global standard, namely the 8th edition of the TNM Classification of Malignant Tumours by the Union for International Cancer Control (UICC).
All radiology reports in RadNLP 2024 diagnose lung cancer at the initial evaluation. There are no reports of lung cancer post-treatment evaluation or different cancer.
Our datasets contain NO personal health information. The radiology reports are not derived from real medical institutions but are created with crowdsourcing by diagnosing de-identified images on Radiopaedia. Task participants requires no complex applications to use our datasets.
