PAIP 2023: Tumor cellularity prediction in pancreatic cancer (supervised learning) and colon cancer (transfer learning)
PAIP 2023 has been selected as a challenge of the IEEE International Symposium on Biomedical Imaging (ISBI 2023)
Notice
The validation submission is re-opened!! (05, Jul. 2023)
About
Participants will be required to tackle the following two tasks.- computation of TC in pancreatic cancer with tumor cell nucleus segmentation using a decent-size training dataset (images and annotations).
- calculating TC in colon cancer with tumor cell nucleus segmentation under the situation of having a tiny training dataset but having a decent training dataset for another task.

Aims
PAIP 2023 challenge aims to promote the development of automatic and reliable TC evaluation algorithms that are flexibly applicable to multiple organs. The PAIP 2023 challenge poses two practical problems for developing automated image analysis tools for reliable TC evaluation.
Motivation
Tumor cellularity (TC) is used to compute the residual
tumor burden in several organs, such as the breast and colon. The
TC is measured based on semantic cell segmentation, which
accurately classifies and delineates individual cells. However,
manual analysis of TC is impractical in clinics because of the large
volumes of pathological images and is unreliable owing to
inconsistent TC values among pathologists. Essentially, tumor cellularity should be calculated by individual cell
counting; however, manual counting is impossible, and human pathologists cannot avoid individual differences in diagnostic performance. Automatic image analysis is the ideal method
for solving this problem, and it can efficiently reduce the workload of
pathologists.
