Classification of brain tumor plays a vital role in medical imaging for accurate diagnosis, treatment, and monitoring. Deep learning approaches have gained significant traction this industry because their ability to extract relevant features from images. The research suggests employing an ensemble classifier with weighted voting mechanism categorize glial cell malignancies such as Astrocytoma, Glioblastoma multiforme, Oligodendroglioma, Ependymoma. proposed technique employs three main classifiers: Convolutional Neural Network (CNN), Long Short Term Memory (C-LSTM), + Conditional Random Fields (DCNN+CRF). algorithms require huge amount input data avoid overfitting. Adaptive Progressive Generative Adversarial Networks (APCGANs) are used produce realistic artificial images efficiently train the methodology. Overall, method strategy consistently outperforms other tested (CNN, C-LSTM, DCNN+CRF). Ensemble attained accuracy 99.4 %, recall - 99.1%, precision- 98.0%, F1-score 99.2%. demonstrates superior performance accurately classifying tumors, making it promising algorithm analysis tasks.

Abstract Glioblastoma (GBM) is an aggressive primary tumor, causing thousands of deaths worldwide every year. The mean survival patients with GBM remains below 20 months despite current available therapies. cells' interactions their stromal counterparts are crucial for tumor development. Astrocytes glial cells that comprise ~50% all brain and therefore likely to establish direct contact cells. As other cell types can hijack fibroblasts or immune facilitate growth, actually activate astrocytes, namely, the associated astrocytes (TAAs), promote invasion in healthy tissue. TAAs have thus been shown be involved growth limited response radiation chemotherapy (i.e., Temozolomide). Nevertheless, even though interest cancer research community increasing, role during development still overlooked. Yet, obtaining in‐depth understanding mechanisms by which influence progression might lead new therapeutic strategies.

Until recently, glial cells have been considered mainly support for neurons in the mammalian brain. However, many studies unveiled a variety of functions including electrolyte homeostasis, inflammation, synapse formation, metabolism, and regulation neurotransmission.
