What DeepSeek does in pathology
- Digitising and managing tissue slides in an image management system (scanners, LIMS, archive)
- Detecting and grading cancer on H&E slides (e.g. Gleason score, mitotic counting, tumour size)
- Counting and quantifying biomarkers in IHC stains (HER2, ER/PR, Ki-67, PD-L1)
- Monitoring slide quality, prioritising cases and providing a second read as quality control
- Very low API costs
- Open weights (MIT), self-hostable
- Strong at reasoning, maths and code
- Large context window (1M tokens)
DeepSeek has a concrete GDPR concern. The DeepSeek service stores personal data in China and was blocked by the Italian regulator in January 2025. Not advisable for regulated sectors unless you host the model yourself within the EU. Weigh this heavily before deploying it in pathology.
Confidentiality and GDPR
GDPR: CautionYou process special category personal data (health) and sometimes data for genetic research. Software for diagnostic use is an in vitro diagnostic medical device: check whether the algorithm is CE-marked under the IVDR for your exact application and tissue type. Many apps are 'research use only'. Choose providers with ISO 27001 and ISO 13485, a data processing agreement and clear data location (EU hosting or on-premise). Also ask whether your slides are used to train models. Under the EU AI Act, medical AI falling under the IVDR is classed as high-risk. Validate every algorithm locally on your own scanner and stains before using it in routine practice.
The DeepSeek service stores data in China and uses it for training by default (with an opt-out). Only an EU self-hosted variant of the open weights is defensible for sensitive data.
