C79.31
Secondary malignant neoplasm of brain
Clinical Classification Guidelines
Medical Intelligence & Overview
Secondary malignant neoplasm of the brain, also known as brain metastasis, occurs when cancer cells spread from a primary tumor located elsewhere in the body to the brain. This condition is a serious complication of cancer and requires careful medical management. Unlike primary brain cancers that originate in the brain tissue itself, secondary brain neoplasms are metastatic tumors that have traveled through the bloodstream or lymphatic system to establish new growths in the brain. Early recognition and treatment are crucial for improving quality of life and managing symptoms.
Causes & Symptoms
Clinical Causes: Primary cancers in other parts of the body such as lung, breast, melanoma, kidney, and colon that metastasize to the brain. Spread of malignant cells through blood vessels or lymphatic channels. Genetic and molecular factors that facilitate tumor cell invasion and dissemination.
Key Symptoms: New or worsening headaches, often persistent or severe. Seizures or convulsions. Neurological deficits such as weakness, numbness, or difficulty speaking. Changes in vision, balance, or coordination. Memory loss, confusion, or personality changes. Nausea and vomiting, especially in the morning.
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a combination of neurological examination and imaging studies. Magnetic resonance imaging (MRI) of the brain is the most sensitive tool for detecting metastatic tumors. Sometimes, a computed tomography (CT) scan is performed. Additional tests may include:
Treatment Protocols: Surgical removal of accessible tumors to reduce pressure and symptom severity. Radiation therapy, such as whole-brain radiation or stereotactic radiosurgery, targeting specific lesions. Chemotherapy tailored to the primary cancer type, though its effectiveness depends on tumor sensitivity. Targeted therapy and immunotherapy in certain cases, especially when specific genetic markers are identified. Supportive care focusing on symptom management, including corticosteroids to reduce swelling and anticonvulsants for seizures.
