Summary
Nonosseous spinal tumors are rare but can be classified by their location within the spinal canal. Understanding these compartments helps in diagnosing various benign and malignant spinal masses.
Area of Science:
- Neurosurgery
- Oncology
- Spinal Pathology
Background:
- Nonosseous spinal tumors are uncommon, presenting a diverse range of benign and malignant conditions.
- Accurate classification of tumor location (intramedullary, intradural extramedullary, extradural) is crucial for diagnosis.
Purpose of the Study:
- To categorize nonosseous spinal tumors based on their compartmental localization.
- To provide a comprehensive overview of common and rare spinal masses within each compartment.
Main Methods:
- A literature review and synthesis of existing data on spinal tumor classification.
- A space-based approach to describe tumor types and their prevalence.
Main Results:
- Ependymomas and astrocytomas are the most frequent intramedullary spinal tumors.
- Nerve sheath tumors and meningiomas are the most common intradural extramedullary tumors.
- Nerve sheath tumors are the predominant nonosseous extradural tumors.
Conclusions:
- Compartmental localization is a key factor in narrowing the differential diagnosis of nonosseous spinal tumors.
- This classification aids in understanding the epidemiology and presentation of various spinal masses.

01:27Tumor Immunotherapy
1.9K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

02:07Tumor Progression
7.4K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

02:17The Tumor Microenvironment
7.8K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

02:40Cancer Stem Cells and Tumor Maintenance
6.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

01:12Loss of Tumor Suppressor Gene Functions
6.1K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
