The Challenge of Distinguishing Between Glioblastoma and Metastasis Tumors

Oct 13, 2025 by wbrum.org 105 views

Introduction

Brain tumors are a complex and life-threatening medical condition that affects millions of people worldwide. These abnormal cell growths can be classified into two main categories: primary tumors, which grow independently, and secondary tumors, which are the result of cancer cell metastasis from other body parts. Among the primary tumors, Glioblastoma is the most common and aggressive type, making it a significant challenge for medical professionals to distinguish between metastasis tumors and high-stage glioblastoma, especially when the origin of the tumor is unknown. This article discusses the development of a classification method using Extreme Learning Machine (ELM) to distinguish between primary and secondary brain tumors based on MRI digital image processing.

Background

Brain tumors are a collection of abnormal cells that form mass in the brain. Clinically, brain tumors are divided into two main categories: primary tumors, which grow independently, and secondary tumors, which are the result of cancer cell metastasis from other body parts. Primary tumors are further classified into different types, including Glioblastoma, which is the most common and aggressive type. Secondary tumors, on the other hand, are the result of cancer cell metastasis from other body parts, such as the lungs, breast, or colon.

The Challenge of Distinguishing Between Glioblastoma and Metastasis Tumors

Limitations in distinguishing between glioblastoma and metastasis tumors through MRI image analysis can cause clinical dilemmas, as both types of tumors require different treatment. Glioblastoma is a high-grade tumor that requires aggressive treatment, including surgery, radiation, and chemotherapy. Metastasis tumors, on the other hand, require a different treatment approach, which may include targeted therapy or immunotherapy. Therefore, accurate diagnosis and classification of brain tumors are crucial for determining the right treatment approach.

The Role of Extreme Learning Machine (ELM) in Brain Tumor Classification

To overcome the challenge of distinguishing between glioblastoma and metastasis tumors, this study aims to develop a classification method using Extreme Learning Machine (ELM). ELM is a type of artificial neural network that is known for its ability to learn quickly and effectively, and produce accurate predictions. ELM was chosen for this study because of its ability to handle high-dimensional data and its ability to learn from a small number of training samples.

Feature Extraction Using Gray Level Co-Occurrence Matrix (GLCM)

In the feature extraction process, this study uses the Gray Level Co-Occurrence Matrix (GLCM), which is a useful tool for analyzing image texture by considering the pixel intensity. GLCM is a matrix that represents the frequency of occurrence of different pixel intensity values in an image. By analyzing the GLCM, it is possible to extract features that are useful for distinguishing between glioblastoma and metastasis tumors.

Experimental Design and Results

The training process is carried out using 70 MRI images, while 30 MRI images are used for testing. The results showed that this system was able to achieve an accuracy level of 96.7% in classifying primary and secondary brain tumors. This result indicates that the use of ELM in brain tumor classification has great potential to assist doctors in determining the right diagnosis.

Conclusion

In conclusion, this study demonstrates the potential of using Extreme Learning Machine (ELM) in brain tumor classification. The results show that ELM can achieve high accuracy in classifying primary and secondary brain tumors. This study highlights the importance of developing accurate classification methods for brain tumors, which can lead to more precise and fast treatment for patients. Further research is necessary to develop this system, by increasing the number of images used and improving image processing techniques.

Future Directions

With advances in technology and analysis methods that continue to develop, it is hoped that there will be more innovations in the classification and handling of brain tumors in the future. This can lead to increased success rates of therapy and improved quality of life for patients. Some potential future directions for this research include:

Increasing the number of images used: Increasing the number of images used in the training and testing process can lead to more accurate classification results.
Improving image processing techniques: Improving image processing techniques, such as image denoising and image enhancement, can lead to more accurate feature extraction and classification results.
Developing new classification methods: Developing new classification methods, such as deep learning-based methods, can lead to more accurate classification results and improved performance.
