Gemcitabine
- Medical Review: Laura M. Spring, MD
Gemcitabine (Gemzar) is an antimetabolite chemotherapy medicine used alone or with other agents to treat metastatic breast cancer. Gemcitabine may also be called gemcitabine hydrochloride.
How gemcitabine works
Gemcitabine works by interfering with the way DNA and RNA develop inside cancer cells. This medicine is similar to a normal substance inside cells, but different enough to interfere with the way cells normally divide and work.
Who gets gemcitabine
Gemcitabine is FDA approved for use in metastatic breast cancer after an anthracyline stops working or if you cannot take it for other reasons.
Gemcitabine may be used for all types of metastatic disease, including triple-negative breast cancer.
How gemcitabine is given
In metastatic breast cancer, gemcitabine is used with paclitaxel (Taxol), with carboplatin (Paraplatin) or on its own.
When given alone, gemcitabine is usually given by vein 3 weeks in a row, followed by a 1 week rest period, but schedules can vary. When given with another chemotherapy agent, it is usually given once per week for 2 weeks followed by a week off.
