In short
The research does not give a single answer for everyone. It depends on whether your cancer can be removed with surgery or has spread to other parts of the body. You should ask your doctor which stage you have and what it means for your options [3].
The details
For cancer that can be removed (resectable), one study found that having chemotherapy before surgery helped patients live longer than having surgery first [2]. This treatment used gemcitabine and S-1 [2]. Another guideline says chemotherapy after surgery can help some patients with pancreatic cancer survive longer [1].
For cancer that has spread (metastatic), surgery is usually not the main option. Instead, chemotherapy is used to control the disease [1]. One strong treatment for this stage is a mix called FOLFIRINOX [4]. This mix helped people live longer than gemcitabine alone in patients with good health status [4].
For cancer that is locally advanced but not yet spread, starting with systemic chemotherapy is often the best choice [1]. Doctors may consider other local treatments after 3 to 4 months of this chemotherapy [1].
What to know
The choice between before or after surgery depends on if your tumor can be safely removed [1]. If you have metastatic cancer, surgery is generally not the primary treatment [1]. Always discuss your specific stage and health with your doctor to decide what is best for you [3].
