Neutrophils are a type of white blood cell. White blood cells protect us from infections. Neutrophils are the “first responders” in the presence of infective pathogens and quickly appear at the site of the infection. These cells ingest and destroy foreign particles. A normal count of neutrophils also called the absolute neutrophil count, ranges from 2.5 to 6. A neutrophil count of less than 1 is called neutropaenia. Neutropaenia is common in patients who are receiving and undergoing chemotherapy and can increase your risk of infection.
Chemotherapy drugs work by destroying the fast-growing cells, which include both cancer cells and healthy cells. The destruction of healthy white blood cells results in neutropaenia.
Neutropaenia is common in patients receiving chemotherapy. Our doctor will test your blood at regular intervals during cancer treatment to test for neutropaenia.
Neutropaenia usually occurs around 7 to 12 days after chemotherapy. This period may differ depending on your type of chemotherapy drug. It is crucial to watch for signs of infection during this period.
It is difficult to prevent neutropaenia. However, during chemotherapy you may receive growth factor injections to stimulate the production of neutrophils. There are several growth factors available such as filgrastim and pegfilgrastim.
If you notice any symptoms of infection, seek medical attention immediately. Minor infections can become serious very quickly. You will need to undergo tests to detect the source of infection and be treated with antibiotics.
When you are neutropaenic, you are at risk of food-borne illnesses. There are precautions you should follow to ensure food safety:
When you visit an emergency department, inform the doctor or nurse that you are undergoing chemotherapy and have the symptoms of infection. Patients receiving chemotherapy should avoid sitting in a waiting room for extended periods.
