[1] [2] The diagnosis is challenging, primarily because symptoms often mimic more common and benign degenerative spinal diseases. [8] [9] Spinal cord compression is commonly found in patients with metastatic malignancy. [10] Back pain is a primary symptom of spinal cord compression in patients with known malignancy. [11] Back pain may prompt a ...
Bone metastasis, or osseous metastatic disease, is a category of cancer metastases that result from primary tumor invasions into bones. Bone-originating primary tumors such as osteosarcoma , chondrosarcoma , and Ewing sarcoma are rare; the most common bone tumor is a metastasis. [ 1 ]
Metastasis occurs in about 39% of patients, most commonly to the lung. Features associated with poor prognosis include a large primary tumor (over 5 cm across), high grade disease, co-existent neurofibromatosis, and the presence of metastases. [5] It is a rare tumor type, with a relatively poor prognosis in children. [6]
Average survival times decline with the presence of metastasis. Primary CNS tumors generally metastasize only within the CNS. One case of metastatic disease to the abdomen via ventriculoperitoneal shunt has been reported with AT/RT . Metastatic dissemination via this mechanism has been reported with other brain tumors, including germinomas ...
The tumor in the lung is then called metastatic breast cancer, not lung cancer. Metastasis is a key element in cancer staging systems such as the TNM staging system, where it represents the "M". In overall stage grouping, metastasis places a cancer in Stage IV. The possibilities of curative treatment are greatly reduced, or often entirely ...
Spinal cord compression is a form of myelopathy in which the spinal cord is compressed. Causes can be bone fragments from a vertebral fracture, a tumor, abscess, ruptured intervertebral disc or other lesion.
Leptomeningeal cancer is a rare complication of cancer in which the disease spreads from the original tumor site to the meninges surrounding the brain and spinal cord. [1] This leads to an inflammatory response, hence the alternative names neoplastic meningitis (NM), malignant meningitis , or carcinomatous meningitis .
[5] [8] Signs and symptoms vary according to tumor site, and prognosis is closely tied to the location of the primary tumor. Common sites of metastasis include the lungs, bone marrow, and bones. [9] [10] There are many classification systems for RMS and a variety of defined histological types. Embryonal rhabdomyosarcoma is the most common type ...
