# Treatment options for pancreatic cancer
The treatment of pancreatic cancer aims to defeat cancer cells while maintaining the best possible quality of life. The choice of which treatment depends on the stage (how far it has spread), overall health, and what medical research shows to be most suitable. Treatments are often combined. Here is an overview of the options per treatment group.

Surgery
ProveniIncluded in official guidelines, or approved by EMA or FDA
Surgical removal of the tumor can offer a chance of cure, especially when the cancer has not yet spread. The most common procedure is the so-called Whipple operation, in which the head of the pancreas is removed together with part of the small intestine and surrounding tissues. For tumors at the tail, that part alone can also be removed. Not everyone can be operated on: sometimes the cancer is too close to important blood vessels or has already spread too far.
The operation is intensive. Known side effects are pain around the wound, fatigue in the weeks afterwards, and in the longer term sometimes problems with nutrition (because the pancreas plays a role in digestion and blood sugar). Many hospitals nowadays use minimally invasive techniques (via small incisions with camera support) where possible, which can help make recovery faster and with less burden.

Chemotherapy
ProveniIncluded in official guidelines, or approved by EMA or FDA
Chemotherapy consists of medicines that attack cancer cells by interrupting their cell division or damaging their DNA. In pancreatic cancer, a combination of three chemotherapies is often given: gemcitabine, 5-FU and cisplatin, sometimes in different schedules.
Chemotherapy can be given before surgery (neoadjuvant) to shrink the tumor and address spread cells. After surgery it is often continued for several more months (adjuvant). Even with inoperable tumors, chemotherapy can help relieve symptoms and prolong life.
Known side effects are nausea, vomiting, fatigue, hair loss, decrease in white blood cells (which promotes infections), and bruising or bleeding (from falling platelets). These side effects vary greatly from person to person and per schedule. Many side effects are treated with supportive medications.

Targeted therapy: KRAS inhibitors
ProveniIncluded in official guidelines, or approved by EMA or FDA
Many pancreatic cancers have a mutation in the KRAS gene, which controls oncogenes (cancer triggers). Until recently, such mutations were difficult to tackle. New KRAS-targeted medicines (such as sotorasib and adagrasib) can now block certain KRAS mutations and are included in official guidelines for patients whose cancer has this mutation.
These medicines work by disabling the KRAS protein, so cancer cells lose their group signal. They are usually combined with other treatments. Research into further refinement of this approach is ongoing (for example for other KRAS subtypes).
Side effects are generally milder than traditional chemotherapy, but can include rash, diarrhea, and hepatotoxicity (liver inflammation), among others.

Targeted therapy: PARP inhibitors
ResearchediPositive results in clinical studies, not yet standard treatment
PARP inhibitors are medicines that block DNA repair proteins (PARP). They work especially well for tumors with defects in DNA repair genes (such as BRCA1/2 mutations). When these genes do not function properly, blocking PARP can lead to more DNA damage and cell death.
In pancreatic cancer with certain genetic abnormalities, PARP inhibitors show promising results, especially in combination with chemotherapy. Research into patient selection (which individuals benefit) and optimal combinations is ongoing. In some countries they are now incorporated into clinical practice; in the Netherlands this can vary from case to case.
Known side effects are fatigue, nausea, anemia, and (rarely) more serious complications.

Immunotherapy
ResearchediPositive results in clinical studies, not yet standard treatment
The immune system can attack cancer, but cancer cells have ways to make themselves invisible. Immunotherapy helps the body find these hiding places by removing certain immune system inhibitors (for example, checkpoint inhibitors).
In pancreatic cancer, results with immunotherapy are only less consistent than in other cancer types, but research continues. Combination with chemotherapy or with specific immune activation seems promising. Many ongoing studies focus on this.
Side effects depend on the type of immunotherapy, but can include inflammatory reactions (where the immune system also attacks the body's own tissues), such as lung toxicity, liver and kidney function disorders, and fatigue.

Radioactive radiation
ProveniIncluded in official guidelines, or approved by EMA or FDA
Radiation uses high-energy rays to damage cancer cells. This is done in a targeted way on the tumor and surrounding lymph nodes. Radiation can be given as a supplement to chemotherapy, especially when surgery is not possible (locally advanced tumor).
Stereotactic body radiotherapy (SBRT) is a recent approach with higher precision and fewer doses: the radiation is more strongly focused on the tumor, with less exposure of surrounding healthy tissue. This is increasingly being investigated in pancreatic cancer.
Side effects can include abdominal pain, nausea, fatigue, and skin irritation. In the longer term, certain organs (intestine, stomach) can become more sensitive. Modern aligned techniques try to minimize this.

Combination schedules with chemotherapy and radiation
ProveniIncluded in official guidelines, or approved by EMA or FDA
Because pancreatic cancer can be aggressive, chemotherapy and radiation are often given together (chemoradiation), especially in the stage where surgery is still possible. This combines the benefits of both: chemotherapy works against cells throughout the body, radiation targets the local area.
This schedule is usually applied after neoadjuvant chemotherapy and before or instead of surgery, depending on how the cancer responds. Studies increasingly compare different sequences and combinations.
Side effects are those of both treatments combined: fatigue, nausea, diarrhea, skin problems, and reduced nutrition.

Supportive care
ProveniIncluded in official guidelines, or approved by EMA or FDA
Because pancreatic cancer and its treatment have major impact, supportive care is essential. This includes managing side effects (nausea, pain), nutritional support (because the pancreas is involved in digestion), psychological support, and guidance with daily activities.
Patients are often prescribed nutrition with extra calories and proteins. Pain relief is a standard part of care. Counseling helps with anxiety, fatigue, and quality of life.

Experimental approaches in ongoing research
ExperimentaliOngoing in study setting, outcome still unknown
There is much research into new approaches:
- **CAR-T cell therapy**: the immune system is genetically modified to better recognize cancer cells. This has been successful in blood cancers; application in pancreatic cancer is in early stages.
- **Tumor-infiltrating lymphocytes (TIL)**: immune cells from the tumor itself are multiplied and given back. Research phases are underway.
- **Modified viral therapies**: viruses are used to infect and break down cancer cells; this is in clinical trials.
- **Targeted therapies against metabolic weaknesses**: research shows that pancreatic cancer uses nutrition and energy in special ways. Medications targeting this are being developed.
- **Biomarkers and diagnostics**: less invasive tests (for example, of circulating tumor DNA in blood) can enable earlier detection and better personalization of treatment.
These approaches are not yet standard available and are only given in study settings to carefully selected patients.

Determining factors for treatment choice
When choosing treatment, the doctor considers, among other things, these points:
- **Stage and location**: where is the cancer located, how far has it spread?
- **Genetic profiles**: does the tumor have KRAS, BRCA or other mutations for which targeted drugs exist?
- **Overall health**: can the body tolerate intensive treatment?
- **Kidney function and liver tests**: some medications require good organ function.
- **Previous treatments**: what has been given before, how did the patient respond?
- **Preference and life situation**: what are the patient's own goals?
