Anemia and Pancreatic Cancer - Causes, Symptoms and Treatment

Understanding Anemia and Pancreatic Cancer

Anemia, a condition in which you lack enough healthy red blood cells to carry adequate oxygen to your body's tissues, is common in people with pancreatic cancer. In fact, around 50 percent of people with pancreatic cancer develop anemia at some point.

What Causes Anemia in Pancreatic Cancer Patients?

There are a few key factors that contribute to anemia development in pancreatic cancer:

• The tumor bleeding into the intestine, which leads to microscopic blood loss over time
• The inflammation caused by pancreatic cancer, which suppresses the production of red blood cells
• Nutrient deficiencies caused by pancreatic cancer, which affects iron absorption needed to produce hemoglobin
• The side effects of surgery, chemotherapy or radiation therapy

Symptoms

Common anemia symptoms to look out for if you have pancreatic cancer include:

• Fatigue, weakness
• Shortness of breath
• Rapid heartbeat
• Pale skin
• Chest pain
• Dizziness, lightheadedness
• Headaches

However, many people experience no symptoms in the early stages of anemia.

Risk Factors

Certain people are at increased risk of developing anemia from pancreatic cancer or its treatments:

• Getting chemotherapy - Some chemo drugs directly damage bone marrow.
• Undergoing radiation - Radiation can harm bone marrow production of red blood cells.
• Experiencing blood loss during surgery.
• Having a nutrient deficient diet makes it harder to produce RBCs.
• Being at an advanced cancer stage increases inflammation.

Diagnosing Anemia

If symptoms occur, your oncologist will likely order blood tests to check for anemia, including:

• Complete blood count (CBC) - Checks levels of RBCs, hemoglobin and hematocrit.
• Iron studies - Measures iron and ferritin levels.
• Vitamin studies - Checks for deficiencies in essential vitamins.

Finding and treating the underlying cause of anemia is also important.

Treating Anemia in Pancreatic Cancer Patients

If you develop anemia from pancreatic cancer, working closely with your healthcare team on effective anemia management is vital for your overall well-being and quality of life.

Treatment Options

Some of the most common medical treatments for anemia include:

• Blood transfusions - Healthy red blood cells are transferred directly into your bloodstream.
• Erythropoiesis-stimulating agents - ESAs stimulate bone marrow to produce more red blood cells.
• Iron supplements - Help restore iron levels so red blood cell production isn't hindered.

Lifestyle Changes

Certain lifestyle measures can also help improve anemia:

• Eat iron-rich foods like red meat, beans, dark leafy greens.
• Take supplements like vitamin B12, folic acid, vitamin C.
• Avoid activities that cause excess bleeding.
• Get enough rest and sleep to reduce fatigue.

Talk to Your Doctor

Work closely with your healthcare team to find the right anemia treatment approach for your situation. Tell your doctor if symptoms persist or worsen despite treatment.

How Anemia Impacts Pancreatic Cancer

Letting pancreatic cancer-related anemia go untreated can negatively impact your cancer in various ways:

• Fatigue makes it harder to complete treatment.
• Decreased quality of life due to constant tiredness.
• Potential delay in surgery if anemia is severe.
• Lower tolerance for chemotherapy and radiation therapy.

Impacts Survival Rates

Some research indicates that anemia leads to poorer survival rates in pancreatic cancer patients. Possible reasons include:

• Prevents patients from receiving adequate therapy dosing.
• Diminishes effectiveness of radiation therapy.
• Increases risk of cancer bleeding and blood clots.
• May reflect more advanced or aggressive tumor stage.

Increases Risk of Comorbidities

Anemia can also contribute to other issues like:

• Severe fatigue, weakness and shortness of breath.
• Impaired heart health due to excess strain.
• Increased infections from compromised immunity.
• Higher risk of falls or injuries.

Managing nutritional deficiencies, inflammation and other factors tied to your anemia may help minimize these risks.

Improving Your Prognosis

While a pancreatic cancer diagnosis is certainly serious, taking proactive steps to monitor and manage treatment side effects like anemia can help safeguard your health.

Working with Your Healthcare Team

Here are some tips for getting the most out of your cancer care when anemia is involved:

• Attend regular blood checks to monitor blood cell counts.
• Tell your doctor about new or worsening anemia symptoms promptly.
• Stick closely to your prescribed treatment regimen.
• Be diligent about nutrition and oral iron or vitamin supplements if recommended.
• Ask about ways to minimize bleeding and optimize RBC production.

Explore Emerging Therapies

Researchers are studying innovative new approaches to treating cancer-related anemia, such as:

• New ESA drugs to stimulate RBC production
• Immunotherapies to target inflammation causing anemia
• Drugs to inhibit proteins that block iron absorption

Ask your doctor if enrolling in a clinical trial evaluating promising new anemia medications could benefit you.

Living Better with Anemia

While anemia can negatively impact quality of life, focus on listening to your body, conserving energy whenever possible, eating a balanced nutrient-dense diet, and working closely with your medical team. With proper monitoring and treatment, it is possible to keep anemia well-managed.

Make overcoming obstacles like anemia an integral part of your pancreatic cancer healing journey.
