IMFINZI FAQs
About stomach (gastric) and gastroesophageal junction cancers that can be removed with surgery
IMFINZI is an immunotherapy. An immunotherapy is a type of cancer treatment that works with your immune system to find and attack cancer cells. IMFINZI may also affect healthy cells.
Chemotherapy attacks fast-growing cells, including cancer cells and sometimes healthy cells. Immunotherapies, like IMFINZI, work with your immune system to find and attack cancer cells. IMFINZI may also affect healthy cells.
The specialists on your care team may include:
- Gastroenterologist – A doctor who specializes in the digestive system
- Medical oncologist – A doctor who is an expert in treating cancer with drugs, such as chemotherapy and immunotherapy. They will provide treatment recommendations
- Surgeon – A doctor that specializes in removing the cancer
- Oncology nurse – A nurse who specializes in caring for patients with cancer. They can help you manage treatment
- Nutritionist – A specialist that helps patients maintain their nutritional needs during treatment and after surgery
IMFINZI and chemotherapy* will be given up to 2 cycles prior to surgery (each cycle is 4 weeks). After surgery, IMFINZI and chemotherapy* will be given up to 2 cycles, followed by IMFINZI alone for 10 cycles. Your doctor will determine exactly how many treatments you need.

While on IMFINZI, you may experience side effects. This is because IMFINZI works with your immune system to treat cancer, which can also affect the way normal organs and tissues work. These problems can sometimes become serious or life-threatening and can lead to death in some cases.

Getting medical treatment right away may help keep these problems from becoming more serious. Your healthcare provider will check you for these problems during your treatment with IMFINZI. Your healthcare provider may treat you with corticosteroid or hormone replacement medicines. Your healthcare provider may also need to delay or completely stop treatment with IMFINZI, if you have severe side effects
