Abstract The parasellar region is the anatomical area around sella turcica that represents a crucial crossroad for important adjacent structures. Several distinct tumors can primarily originate from this area, most common being meningiomas, gliomas, embryonal cell tumors, germ and craniopharyngiomas. In addition, number of systemic inflammatory disorders also affect region, commonly involving pituitary. These lesions have different pathologic characteristics malignant potential according to new World Health Organization CNS5 2021 classification. Signs symptoms may be nonspecific are mostly related mass effect on surrounding structures and/or impairment endocrine function, whereas vast majority lack secretory component. mutational signature analysis based advances in molecular techniques has recently enabled identification specific gene mutations or signaling pathway aberrations. developments serve as powerful means delineate pathophysiology these diagnostic, prognostic, therapeutic tool, particularly high-risk populations. Treatment options include surgery alone combination with radiotherapy, chemotherapy, disease-specific medical therapy, order prevent recurrence further tumor growth along replacement coexistent pituitary hormonal deficiencies. comprehensive review, we present current state-of-the-art histopathology biology lesions, which often represent diagnostic challenge, utilized by dedicated multidisciplinary team diagnosis, monitoring, treatment lesions.

Immune cell effector therapies, including chimeric antigen receptor (CAR)-T cells, T-cell (TCR) T natural killer (NK) and macrophage-based represent a transformative approach to cancer treatment, harnessing the immune system target eradicate malignant cells. CAR-T therapy, most established among these, involves engineering cells express CARs specific antigens, showing remarkable efficacy in hematologic malignancies like leukemias, B-cell lymphomas, multiple myeloma. Similarly, TCR-modified which reprogram recognize intracellular tumor antigens presented by major histocompatibility complex (MHC) molecules, offer promise for range of solid tumors. NK-cell therapies leverage NK cells' innate cytotoxicity, providing an allogeneic that avoids some immune-related complications associated with T-cell-based therapies. Macrophage-based still early stages development, focus on reprogramming macrophages stimulate response against microenvironment. Despite their promise, socioeconomic regulatory challenges hinder accessibility scalability These treatments are costly, currently exceeding $400,000 per patient, creating significant disparities access based status geographic location. The high manufacturing costs stem from personalized, labor-intensive processes harvesting, modifying, expanding patients' Moreover, logistics delivering these limit reach, particularly low-resource settings.
