Introduction #
The creators of the CCAgT: Images of Cervical Cells with AgNOR Stain Technique dataset emphasize the significance of cervical cancer, a major health concern for women as the second most prevalent cancer. The dataset comprises 9,339 images with a resolution of 1600×1200 pixels, where each pixel measures 0.111µm x 0.111µm. These images are extracted from 15 different slides stained with the AgNOR (Argyrophilic Nucleolar Organizer Regions) technique and include at least one label per image, totaling over sixty-three thousand annotations.
Early detection methods are imperative to combat this deadly disease. Cytology stands as a promising noninvasive alternative to biopsy for diagnosing malignant lesions, providing essential insights into cell characteristics. The process involves staining slides to visualize cell nuclei for accurate diagnosis. This dataset explores the use of silver-stained slides, specifically employing the AgNOR method, which exhibits substantial potential for diagnosing lesion malignancy. It’s important to note that this method remains underexplored, especially in the context of computational approaches.
Factors contributing to this challenge include inadequate or nonexistent screening measures leading to late-stage detection and limited availability or affordability of standard treatment options. Infection by the Human Papillomavirus (HPV) serves as a primary cause of cervical cancer. Early detection and appropriate treatment can result in a cure; however, early detection remains a formidable task. Biopsy remains the gold standard for cancer and pre-cancerous lesion detection, although its invasive nature limits its use to extreme cases.
The authors note that cancer cells typically exhibit abnormal DNA content, a condition known as aneuploidy, which is associated with tumorigenesis. Increased protein synthesis in aneuploid cells characterizes the transition from normal to malignant cells. Argyrophilic Nucleolar Organizer Regions (AgNORs) can serve as valuable markers for quantifying cell proliferation, differentiation, and malignant transformation. AgNORs offer the advantage of simplicity and cost-effectiveness in detecting cell proliferation. Reports highlight the diagnostic and prognostic potential of AgNORs in cervical cytology. One diagnostic approach involves counting NORs, which are easily identifiable through the AgNOR staining technique. NORs are loops of DNA in cell nuclei containing ribosomal RNA genes, making them identifiable through AgNOR staining due to their interaction with argyrophilic nuclear proteins. While manual evaluation of AgNORs is commonly practised, it is prone to issues like variation in visual perception, varying levels of cytologist expertise, slow processing times, and human errors.
The methodology of gaining the images encompasses several key steps. Initially, fields are generated from whole-slide images, followed by data splitting into training (52%), validation (35%), and test (13%) sets. Note, that splits are not pre-defined. The next step involves training a neural network, and finally, the results are evaluated.
The images were obtained from examinations conducted on women treated at the Gynecology and Colposcopy Outpatient Clinic at the Federal University of Santa Catarina (HU-UFSC). These women had cytological alterations in previous exams, leading to further gynecological exams, colposcopy, and biopsies. For image acquisition, a ZEISS Axio Scanner.Z1 with a Hitachi HV-F202SCL as the imaging device was utilized. Image processing resulted in single image files with dimensions of approximately 232,000 x 169,000 pixels, with pixel dimensions of 0.111μm x 0.111μm. Image fields were generated, and a histogram analysis was performed to eliminate fields corresponding to slide borders.
There are three categories labeled with corresponding classes: nucleus, cluster, and satellite
Random AgNOR subimages. Nuclei are labeled with yellow dashes, clusters with green and satellites are denoted by blue dashes. All unlabeled regions were considered to belong to “background class”.
In version 2, there are a total of 7 categories with added distinctions between previous classes: nucleus out of focus, overlapped nuclei, non-viable nucleus, and leukocyte nucleus.
Each slide can have some differences in the stain coloration, it can be seen that an image created from different images of different slides:
The research was approved by the UFSC Research Ethics Committee (CEPSH), protocol number 57423616.3.0000.0121. All patients involved were informed about the objectives of the study, and those who agreed to participate signed an informed consent form.
Summary #
CCAgT: Images of Cervical Cells with AgNOR Stain Technique v2.0 is a dataset for instance segmentation, semantic segmentation, and object detection tasks. It is used in the biomedical research.
The dataset consists of 9090 images with 59036 labeled objects belonging to 7 different classes including nucleus, cluster, nucleus out of focus, and other: satellite, leukocyte nucleus, non-viable nucleus, and overlapped nuclei.
Images in the CCAgT dataset have pixel-level instance segmentation annotations. Due to the nature of the instance segmentation task, it can be automatically transformed into a semantic segmentation (only one mask for every class) or object detection (bounding boxes for every object) tasks. All images are labeled (i.e. with annotations). There are no pre-defined train/val/test splits in the dataset. The dataset was released in 2022 by the Universidade Federal de Santa Catarina, Brazil.
Here is the visualized example grid with animated annotations:
