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 scan to confirm or exclude spinal metastasis. Rapid identification and intervention of metastatic spinal cord compression is ...
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]
The most common cancer among women in the United States is breast cancer (123.7 per 100,000), followed by lung cancer (51.5 per 100,000) and colorectal cancer (33.6 per 100,000), but lung cancer surpasses breast cancer as the leading cause of cancer death among women. [13]
Survival rate is a part of survival analysis.It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy.
The ASCO study of the 188 documented AT/RT cases prior to 2004 found 30% of the cases had metastasis at diagnosis. [3] Metastatic spread to the meninges (leptomenigeal spread sometimes referred to as sugar coating) is common both initially and with relapse. Average survival times decline with the presence of metastasis.
Cancer treatments are a wide range of treatments available for the many different types of cancer, with each cancer type needing its own specific treatment. [1] Treatments can include surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy including small-molecule drugs or monoclonal antibodies, [2] and PARP inhibitors such as olaparib. [3]
Given the high incidence of breast, lung and prostate cancer, these patients account for > 80% of patients with bone metastases. [15] For patients with advanced metastatic disease involving the bone, median survival from the time of diagnosis of a bone metastasis varies by primary tumor type. A list is included below: [26] Breast: 19–25 months
Studies have shown that CTC clusters are associated with increased metastatic potential and poor prognosis. For example, research has demonstrated that patients with prostate cancer who have only single CTCs exhibit an eight-fold longer mean survival rate compared to those with CTC clusters.
