A new dataset for tumours of the lung

The International Academy of Cytology (IAC) said in a statement: "This comprehensive dataset has been devised for small diagnostic biopsy specimens and can be used for provisional and final reports. It can be used for benign tumours or other non-neoplastic specimens at the discretion of the cytopathologist/pathologist and offers high flexibility allowing a laboratory the use the one data set report for all lung biopsy specimens, whether or not the final report is one of cancer or a benign tumour or inflammatory process."

The dataset has been developed for small diagnostic biopsy specimens and cytopathological specimens of lung cancer. It can also be used for benign tumours or other non-neoplastic specimens at the discretion of the cytopathologist/pathologist. This flexibility of usage allows for a laboratory to use the one data set report for all lung biopsy specimens, whether or not the final report is one of cancer or a benign tumour or inflammatory process.

This dataset is a collaboration between the International Collaboration of Cancer Reporting and the IAC.

1st edition – December 2023. This dataset aligns with the 2021 World Health Organization (WHO) Classification of Thoracic Tumours, 5th edition, and the 2022 WHO System for Reporting Lung Cytopathology, 1st edition.
