What does a high Oncotype score mean?
A high score means the cancer has a higher chance of returning and you have a higher chance of benefiting from chemotherapy. For example, patients with a high score often choose more aggressive treatment options including chemotherapy, than patients with low scores.
How accurate is Oncotype DX test for breast cancer?
The studies showed that 99% of those with low Oncotype DX scores who were primarily treated using hormonal therapy alone, WITHOUT chemotherapy, were cancer free after 5 years. To date, more than 170,000 breast cancer patients have changed their treatment decision based the Oncotype DX test.
What stage is invasive ductal carcinoma?
Generally, the stage of invasive ductal carcinoma is described as a number on a scale of I through IV. Stages I, II, and III describe early-stage cancers, and stage IV describes cancers that have spread outside the breast to other parts of the body, such as the bones or liver.
How much does chemo reduce risk of recurrence?
Chemotherapy did appear to have some benefit in women who were age 50 or younger with a recurrence score of 16 to 25. For this age group, there were 2% fewer cases of cancer returning for recurrence scores between 16 to 20, and 7% fewer cases for scores between 21 to 25.
Does chemotherapy prevent metastasis?
Chemo is considered a systemic treatment because the drugs travels throughout the body, and can kill cancer cells that have spread (metastasized) to parts of the body far away from the original (primary) tumor. This makes it different from treatments like surgery and radiation.
How do you know if breast cancer has metastasized?
Symptoms of metastatic breast cancer
- Bone pain or bone fractures due to tumor cells spreading to the bones or spinal cord.
- Headaches or dizziness when cancer has spread to the brain.
- Shortness of breath or chest pain, caused by lung cancer.
- Jaundice or stomach swelling.
Is ductal carcinoma aggressive?
DCIS is a noninvasive form of early breast cancer in which abnormal cells are localized to milk ducts in the breast. In some cases, however, DCIS may become aggressive and spread to surrounding tissue, but until now pathologists have not had a way to identify which cases may become invasive.
How aggressive is invasive ductal carcinoma?
The five-year survival rate for localized invasive ductal carcinoma is high — nearly 100% when treated early on. If the cancer has spread to other tissues in the region, the five-year survival rate is 86%. If the cancer has metastasized to distant areas of your body, the five-year survival rate is 28%.
What is the difference between recurrence and metastasis?
Regional recurrence means that the tumor has grown into lymph nodes or tissues near the original cancer. Distant recurrence means the cancer has spread to organs or tissues far from the original cancer. When cancer spreads to a distant place in the body, it is called metastasis or metastatic cancer.
