Background: A timely diagnosis of early gastric cancer (EGC) can greatly reduce the death rate of patients. However, the manual detection of EGC is a costly and low-accuracy task. The artificial intelligence (AI) method based on deep learning is considered as a potential method to detect EGC. AI methods have outperformed endoscopists in EGC detection, especially with the use of the different region convolutional neural network (RCNN) models recently reported. However, no studies compared the performances of different RCNN series models.
Objective: This study aimed to compare the performances of different RCNN series models for EGC.
Methods: Three typical RCNN models were used to detect gastric cancer using 3659 gastroscopic images, including 1434 images of EGC: Faster RCNN, Cascade RCNN, and Mask RCNN.
Results: The models were evaluated in terms of specificity, accuracy, precision, recall, and AP. Fast RCNN, Cascade RCNN, and Mask RCNN had similar accuracy (0.935, 0.938, and 0.935). The specificity of Cascade RCNN was 0.946, which was slightly higher than 0.908 for Faster RCNN and 0.908 for Mask RCNN.
Conclusion: Faster RCNN and Mask RCNN place more emphasis on positive detection, and Cascade RCNN places more emphasis on negative detection. These methods based on deep learning were conducive to helping in early cancer diagnosis using endoscopic images.

Article Synopsis
- HER2 assessment is crucial for selecting patients for anti-HER2 treatments, but manually analyzing HER2 amplification is time-consuming and prone to errors due to subjective interpretations and complex cell imagery.
- To overcome these challenges, a new deep learning model has been developed that can accurately quantify HER2 amplification status in breast cancer by analyzing FISH and DISH datasets, achieving high accuracy and outperforming existing methods.
- The model was also successfully applied to assess HER2 amplification in gastric cancer patients, yielding promising results with high accuracy and precision, indicating its potential beyond breast cancer applications.

Objectives: Brain tumor detection, classification and segmentation are challenging due to the heterogeneous nature of brain tumors. Different deep learning-based algorithms are available for object detection; however, the performance of detection algorithms on brain tumor data has not been widely explored. Therefore, we aim to compare different object detection algorithms (Faster R-CNN, YOLO & SSD) for brain tumor detection on MRI data.
