Lung and colon cancer classification using medical imaging: a feature engineering approach

摘要

Lung and colon cancers lead to a significant portion of deaths. Their simultaneous occurrence is uncommon, however, in theabsence of early diagnosis, the metastasis of cancer cells is very high between these two organs. Currently, histopathologicaldiagnosis and appropriate treatment are the only way to improve the chances of survival and reduce cancer mortality. Usingartificial intelligence in the histopathological diagnosis of colon and lung cancer can provide significant help to specialists inidentifying cases of colon and lung cancers with less effort, time and cost. The objective of this study is to set up a computeraideddiagnostic system that can accurately classify five types of colon and lung tissues (two classes for colon cancer andthree classes for lung cancer) by analyzing their histopathological images. Using machine learning, features engineeringand image processing techniques, the six models XGBoost, SVM, RF, LDA, MLP and LightGBM were used to perform theclassification of histopathological images of lung and colon cancers that were acquired from the LC25000 dataset. The mainadvantage of using machine learning models is that they allow a better interpretability of the classification model since theyare based on feature engineering; however, deep learning models are black box networks whose working is very difficult tounderstand due to the complex network design. The acquired experimental results show that machine learning models givesatisfactory results and are very precise in identifying classes of lung and colon cancer subtypes. The XGBoost model gavethe best performance with an accuracy of 99% and a F1-score of 98.8%. The implementation and the development of thismodel will help healthcare specialists identify types of colon and lung cancers. The code will be available upon request.
