Chemotherapy uses drugs to kill pancreatic cancer cells. The drugs enter the bloodstream and travel through the body. Targeted therapy attacks or blocks what the cancer needs to grow and spread.
Chemotherapy may be used:
- Before surgery—to shrink the tumor so less tissue needs to be removed
- After surgery—to kill leftover cancer cells and lower the risk of it coming back
- To help ease problems of cancer that's spread and help with living longer
For this type of cancer, radiation therapy is most often used with chemotherapy.
Chemotherapy Drugs and Delivery
There are many types of these drugs. For pancreatic cancer, they work better when more than one is used. The choice and blend of drugs will be based on your cancer type and how you react to the drugs. The most common are:
- Fluorouracil (5-FU)
Chemotherapy is most often given through an IV. But, some come in pill form. They're delivered in cycles over a set period. Your doctor will help find out how many cycles are needed and which drugs will work best.
Drugs are made to kill cancer, but they also harm healthy cells. The death of cancer cells and impact on healthy cells can cause a range of problems. The most common are:
Targeted therapy drugs attack cancer cells without harming healthy cells. Erlotinib is the only one used on pancreatic cancer. It's made to block a certain protein that makes the tumor grow. Erlotinib is given with gemcitabine.
Some problems are:
- Rash, mainly on the face and neck
- Feeling tired
- Loss of hunger
Managing Side Effects
There are many ways to control problems. In some cases, the drugs can be changed to lessen how they make you feel. The earlier these problems are brought up to your doctor, the more likely they will be controlled.
