Chemotherapy and risk of infection

What is Chemotherapy?

Chemotherapy is a form of cancer treatment that uses powerful drugs to kill rapidly dividing cancer cells. While chemotherapy can be highly effective in treating cancer, it also comes with a number of side effects, including an increased risk of infection.

Chemotherapy can also damage healthy cells that divide rapidly, such as those in the bone marrow. This damage can lead to a decrease in the number of white blood cells, which are responsible for fighting off infections. When a patient’s white blood cell count drops too low, they are at an increased risk of developing infections.

There are a number of different types of infections that chemotherapy patients are at risk for. One of the most common is a bacterial infection. Bacteria are everywhere, and our bodies have natural defenses against them. However, when a patient’s white blood cell count drops, their body is less able to fight off bacterial infections. This can lead to infections such as pneumonia, skin infections, and urinary tract infections.

People getting chemotherapy are also at an increased risk of viral infections. Viruses are responsible for many common illnesses, such as the flu and the common cold. While most healthy people are able to fight off these infections with little difficulty, patients undergoing chemotherapy may have a more difficult time. This is because their immune systems are weakened, making it easier for viruses to take hold.

Fungal infections are another risk for chemotherapy patients. Fungi are common in our environment and are normally kept in check by our immune systems. However, when a patient’s immune system is weakened, fungal infections can become a problem. Fungal infections can be difficult to treat and can cause serious complications.

What can be done to decrease the risk of infection? There are a number of things that patients can do to help protect themselves, including:

  1. Practice good hygiene: Regular hand washing and avoiding contact with sick people can help prevent the spread of infection.
  2. Avoid large crowds: Being around large groups of people, such as at concerts or sporting events, can increase the risk of exposure to infectious diseases.
  3. Stay up-to-date on vaccinations: Getting vaccinated can help protect against certain infectious diseases.
  4. Take antibiotics or antivirals as prescribed: In some cases, chemotherapy patients may be given antibiotics or antiviral medications to help prevent infections.
  5. Contact their healthcare provider if they have symptoms of an infection: Early detection and treatment of infections can help prevent them from becoming more serious.


Ampullary Cancer

Ampullary cancer is a rare type that develops in the ampulla, a small sac-like structure where the bile duct and pancreatic duct enter the duodenum (the first part of the small intestine). Ampullary cancer often has symptoms similar to pancreatic cancer that are sometimes mistaken for the disease. The ampulla of Vater secretes digestive enzymes into the duodenum and regulates bile flow from the liver and gallbladder. This cancer is sometimes referred to as periampullary cancer because it can also develop in nearby tissues, such as the pancreas or bile duct.

Most ampullary cancers are adenocarcinomas, which begin in cells lining the inside of the ampulla and producing mucus. These cancers are usually slow-growing and do not spread (metastasize) to other body parts. However, ampullary cancer can be challenging to treat because it is often not caught in its early stages. By the time it is diagnosed, cancer may have spread beyond the ampulla and into nearby tissues.

What causes Ampullary Cancer

The cause of ampullary cancer is unknown but speculated to occur when normal cells in the ampulla start to grow out of control. Symptoms of ampullary cancer include pain in the abdomen, weight loss, jaundice (yellowing of the skin and eyes), and diarrhea or constipation.

Several risk factors for developing ampullary cancer include chronic pancreatitis, familial adenomatous polyposis (FAP), and specific inherited genetic syndromes such as Lynch syndrome. Smoking is also a risk factor. People with these conditions should discuss ways to reduce risk with their doctor.

How is Ampullary Cancer Diagnosed?

Ampullary cancer is diagnosed through a combination of medical imaging tests, such as CT, MRI, and endoscopic procedures, such as upper endoscopy. A biopsy, where a small tissue sample is used for examination under a microscope, is often needed to confirm the diagnosis.

What are the available treatments?

Treatment for ampullary cancer may include surgery, radiation therapy, or chemotherapy. The treatment type depends on the cancer stage (how far it has spread) and the person’s overall health. Surgery is the most common treatment for ampullary cancer. In some cases, only part of the ampulla needs to be removed. However, a more extensive operation, such as pancreaticoduodenectomy (also called a Whipple procedure), may be necessary if cancer has spread beyond the ampulla.

Radiation therapy and chemotherapy are used to treat ampullary cancer. These treatments are given before or after surgery, depending on the cancer stage. Clinical trials testing new therapies for ampullary cancer are always ongoing. People with this condition should speak with their doctor about all treatment options, including clinical trials.

Ampullary cancer is a rare but serious condition. However, treatment has improved recently, and with early diagnosis and proper treatment, patients with ampullary cancer can often lead long and healthy lives.
