People living with pancreatic cancer face a higher risk of blood clots, a condition called hypercoagulability. Blood clots can be serious, affecting both treatment and overall health. This article explains why pancreatic cancer increases clotting risk, the signs to watch for, and how it can be managed to improve care and outcomes.
Why Does Pancreatic Cancer Increase Blood Clotting Risk?
Pancreatic cancer creates a perfect storm for blood clotting due to three main reasons:
1. Tumor-related factors: Pancreatic cancer cells release proteins like tissue factor and thrombin, which trigger blood clotting.
2. Changes in blood composition: The cancer increases levels of fibrinogen, factor VIII, and D-dimer—all linked to clotting.
3. Cancer treatments: Chemotherapy, surgery, and the use of central venous catheters (a tube in a vein) can further raise clotting risks.
Timely access to new therapies is essential. Read about the importance of drug approval transparency in improving care.
Types of Blood Clot Complications
Blood clots can form in different parts of the body, causing serious problems such as:
• Deep Vein Thrombosis (DVT): Blood clots in the legs.
• Pulmonary Embolism (PE): Clots that break off and travel to the lungs.
• Visceral Vein Thrombosis: Clots in veins of the abdomen.
• Arterial Thromboembolism: Clots that block blood flow in arteries.
Understanding your treatment options can help identify risks and address complications.
How Common Are Blood Clots in Pancreatic Cancer?
Blood clots are very common in people with pancreatic cancer, with studies showing rates between 17% and 57%. Risk factors include:
• Late-stage cancer.
• Large tumors.
• Chemotherapy.
• Use of central venous catheters.
• Long periods of immobility.
• Other health issues like diabetes or heart disease.
For those considering participation in clinical trials, discussing blood clot risks with your care team is critical.
Recognizing Symptoms and Diagnosis
It’s important to watch for the symptoms of blood clots and seek medical help immediately.
Common symptoms include:
• DVT: Swelling, pain, or redness in the legs.
• Pulmonary embolism: Sudden shortness of breath, chest pain, or a rapid heartbeat.
• Visceral vein thrombosis: Abdominal pain, nausea, or yellowing of the skin (jaundice).
Early diagnosis improves outcomes. Explore how genetic testing can help you uncover risks related to pancreatic cancer.
Managing and Preventing Blood Clots
There are ways to reduce the risk of blood clots and treat them effectively:
1. Blood thinners (anticoagulation therapy): Medications like low-molecular-weight heparin (LMWH) are often used because they are safer and more effective than warfarin for people with cancer.
2. Mechanical prevention: Tools like compression stockings or devices that improve blood flow in the legs can help prevent clots.
3. Risk assessments: Regular checks are essential, especially before surgery or during chemotherapy, to manage clotting risks.

How Do Blood Clots Affect Prognosis?
Blood clotting doesn’t just cause complications—it can also affect survival. For example, people with longer clotting times, measured by prothrombin time-international normalized ratio (PT-INR), may face a poorer prognosis, even after surgery.
Managing blood clots early and effectively is a key part of improving outcomes for people living with pancreatic cancer.
Ongoing Research
Researchers continue to study how pancreatic cancer triggers blood clotting. They are investigating specific proteins produced by cancer cells and looking for new treatments to prevent clots. This research could lead to better care and improved survival rates for people living with pancreatic cancer.

Conclusion
Blood clotting is a serious concern for people living with pancreatic cancer, but it can be managed with the right care. Recognizing symptoms, understanding risk factors, and taking steps to prevent clots are critical for improving outcomes. With ongoing research and greater awareness, we can continue to improve care and quality of life for people living with this disease.
Questions and Answers
What causes increased blood clotting risk in pancreatic cancer patients?
Pancreatic cancer can increase the risk of blood clots because cancer cells release substances that trigger clotting. It also changes the makeup of the blood, making it easier for clots to form. Treatments like chemotherapy, surgery, and catheters can further raise this risk.
How common are blood clots in people with pancreatic cancer?
Blood clots are very common in pancreatic cancer, affecting 1 in 5 to more than half of all people with the disease. The risk is higher for those with advanced cancer, large tumors, or who are undergoing treatments like chemotherapy or using catheters.
What types of blood clot complications can occur in pancreatic cancer?
Common blood clot problems include clots in the legs (deep vein thrombosis or DVT), clots that travel to the lungs (pulmonary embolism or PE), clots in the belly (visceral vein thrombosis), and clots that block blood flow in arteries (arterial thromboembolism).
What are the symptoms of blood clots in pancreatic cancer patients?
Symptoms of clots include swelling, pain, or redness in the legs for DVT. For PE, it can be sudden shortness of breath, chest pain, or a fast heartbeat. Belly clots can cause stomach pain, nausea, or yellowing of the skin (jaundice).
How are blood clots diagnosed in pancreatic cancer patients?
Doctors look for blood clots using physical exams, imaging like ultrasounds or CT scans, blood tests, and by reviewing symptoms and health history. Finding clots early is very important for treatment.
What treatments are available for managing blood clots in pancreatic cancer?
Blood clots are treated with blood-thinning medicines like low-molecular-weight heparin (LMWH), which is safer for people with cancer. Some patients may also use compression stockings or devices to improve blood flow.
Can blood clots in pancreatic cancer be prevented?
You can reduce the risk of blood clots, not prevent them, by staying active, drinking plenty of water, taking prescribed blood thinners, wearing compression stockings, and moving around soon after surgery. Talk to your care team about other ways to stay safe.
How do blood clots affect the prognosis of pancreatic cancer?
Blood clots can make pancreatic cancer harder to treat and may lead to worse outcomes. Managing them early can improve health and give people a better chance at recovery.
What ongoing research is being conducted on blood clotting in pancreatic cancer?
Researchers are studying how cancer causes blood clots, testing new treatments, and looking for signs in the blood that could predict clot risks. These studies aim to improve care and survival for people with pancreatic cancer.
How can Canadians with pancreatic cancer and caregivers stay informed about blood clotting risks in pancreatic cancer?
Stay informed by talking to your healthcare team, joining support groups, and following trusted cancer organizations. You can also ask about clinical trials or genetic testing that may provide more personalized care options.
