Authoritative information and practical advice from the nation's cancer experts about carcinoma of unknown primary (CUP), also known as occult primary malignancy, includes official medical data on signs, symptoms, treatment options, surgery, radiation, drugs, chemotherapy, staging, biology, prognosis, and survival, with a complete glossary of technical medical terms and current references. Starting with the basics, and advancing to detailed patient-oriented and physician-quality information, this comprehensive in-depth compilation gives empowered patients, families, caregivers, nurses, and physicians the knowledge they need to understand the diagnosis and treatment of CUP. Comprehensive data on clinical trials related to CUP is included.

Carcinoma of unknown primary (CUP) is a rare disease in which malignant (cancer) cells are found in the body but the place the cancer began is not known. Cancer can form in any tissue of the body. The primary cancer (the cancer that first formed) can spread to other parts of the body. This process is called metastasis. Cancer cells usually look like the cells in the type of tissue in which the cancer began. For example, breast cancer cells may spread to the lung. Because the cancer began in the breast, the cancer cells in the lung look like breast cancer cells. Sometimes doctors find where the cancer has spread but cannot find where in the body the cancer first began to grow. This type of cancer is called a cancer of unknown primary (CUP) or occult primary tumor. Tests are done to find where the primary cancer began and to get information about where the cancer has spread. When tests are able to find the primary cancer, the cancer is no longer a CUP and treatment is based on the type of primary cancer. Sometimes the primary cancer is never found. The primary cancer (the cancer that first formed) may not be found either because the primary cancer is very small and grows slowly, or the body's immune system killed the primary cancer.
