The place where it began, also called the primary site, is unknown. These cases make up about 2% to 5% of cancers diagnosed in the United States.
Why is the prognosis for cancer of unknown primary patients poor?
Cancer of unknown primary (CUP) includes many different cancer types, so it’s hard to provide meaningful survival statistics for these cancers as a group. In general, these are difficult cancers for several reasons: When they are first diagnosed, these cancers have already spread beyond the site where they started.
How long can you live with unknown primary cancer?
When all CUP types are looked at together, average survival time is about 9 to 12 months after diagnosis. However, survival rates vary greatly depending on the where the cancer is located, how much it has spread, the cancer cell type, treatments, and more.
What is the life expectancy of someone with metastatic cancer?
A patient with widespread metastasis or with metastasis to the lymph nodes has a life expectancy of less than six weeks. A patient with metastasis to the brain has a more variable life expectancy (one to 16 months) depending on the number and location of lesions and the specifics of treatment.
What type of cancer has the lowest survival rate?
The cancers with the lowest five-year survival estimates are mesothelioma (7.2%), pancreatic cancer (7.3%) and brain cancer (12.8%). The highest five-year survival estimates are seen in patients with testicular cancer (97%), melanoma of skin (92.3%) and prostate cancer (88%).
What happens when you can’t find the primary cancer?
If the primary cancer can’t be found, tests on cells from the secondary cancer can often suggest what the primary cancer is most likely to be. This helps your doctor plan the treatment. They will also try to learn as much as possible about the spread of the cancer, your symptoms and your medical history.
How does unknown primary cancer develop?
In carcinoma of unknown primary, the cancer cells that spread to other parts of the body are found. But the original tumor isn’t found. This can happen if: The original cancer is too small to be detected by imaging tests.
Is cancer of unknown primary hereditary?
Summary: Cancer usually begins in one location and then spreads, but in 3 percent to 5 percent of cancer patients, the tissue where a cancer begins is unknown. Family members of patients with cancers of unknown origin have a higher risk for getting those and other types of cancers, suggests a new study.
Is metastatic poorly differentiated carcinoma curable?
It is now clear that some patients with poorly differentiated carcinoma of unknown primary site have extremely responsive neoplasms, and some are curable with combination chemotherapy.
Are cups curable?
Although most cases of CUP can’t be cured, treatment can keep some cancers under control for months or years.
What is the hardest cancer to detect?
Ovarian cancer is estimated to affect more than 22,000 women each year and is the fifth leading cause of cancer deaths among women, according to American Cancer Society. Unlike other gynecologic cancers, there are no screening tests for ovarian cancer.
