Background:

Brain tumor segmentation is vital for cancer diagnosis and treatment planning.
Accurate segmentation of tumor sub-regions (necrotic, enhancing, edematous) offers detailed clinical insights.
Existing weakly supervised methods often overlook multi-label sub-region segmentation.

Purpose of the Study:

To develop an end-to-end weakly supervised model for multi-label brain tumor sub-region segmentation.
To address the limitations of current methods in segmenting complex tumor structures without pixel-level annotations.
To advance diagnostic capabilities through improved segmentation accuracy.

Main Methods:

Proposed a Transformer-based segmentation method (WS-MTST) for weakly supervised multi-label brain tumor segmentation.
Utilized well-designed loss functions and a contrastive learning pre-training strategy.
Developed the first end-to-end weakly supervised model specifically for multi-label brain tumor sub-region segmentation.

Main Results:

Achieved state-of-the-art performance on the BraTS (2018-2020) dataset.
Demonstrated effective segmentation of necrotic, enhancing, and edematous brain tumor sub-regions.
Validated the model's capability in handling complex multi-label segmentation tasks.

Conclusions:

The proposed WS-MTST method offers a significant advancement in weakly supervised brain tumor segmentation.
This approach provides a more detailed and clinically relevant segmentation of brain tumors.
The method shows strong potential for improving brain cancer diagnosis and treatment guidance.
