How does SCLC affect the body?
SCLC makes up about 15 percent of all lung cancers, and many will be treated with chemotherapy, radiation, or both. 1 SCLC can spread throughout the body (metastasize). One of the places it tends to spread to is the brain. This can cause many serious issues that can impact a person’s quality of life, including seizures.
Does PCI help with lung cancer?
Some have suggested that PCI decreases the risk of lung cancer’s spread to the brain and improves overall survival time. Others have suggested that these benefits may only be found in those who have more limited-stage SCLC (cancer that is detected early and has not spread to other parts of the body). 2,3.
Is PCI recommended for lung cancer?
PCI may be recommended in a variety of different situations. Often, it is for people whose lung cancer has responded to chemotherapy and other radiation. Your doctor can help you determine if PCI is right for your specific case.
Why are prophylactic antibiotics not given?
Prophylactic antibiotics are avoided whenever possible in health care, as the overuse of antibiotics has led to antibiotic resistance, and provides no benefit to the patient. There may be individual instances where the use of antibiotics prior to surgery is deemed to be appropriate, or when a patient is sick enough to warrant the use of antibiotics before blood cultures or other lab results confirm the presence of infection. In these cases, the potential benefit outweighs the risk of harm, and the physician chooses to utilize antibiotics.

Purpose of The Procedure
Risks and Contraindications
- Prophylactic cranial irradiation can play an important role in the prevention of brain metastases by killing metastatic cancer cells in the brain. The radiation dose is far lower than that used to cure solid tumors but significantly higher than that used for imaging tests like computed tomography (CT) scans. The repeated exposure to radiation of this level can lead to neurotoxicity in which br…
Before The Procedure
- The decision to use prophylactic cranial irradiation is a very personal one. Due to the increased risk of neurotoxicity and neurocognitive impairment, the benefits and risks need to be carefully weighed in tandem with your long-term prognosis. In addition, your healthcare provider will need to assess your performance status—usually rated on a scale of 0 (completely active) to 4 (comp…
Simulation
- Before your first treatment is scheduled, you will need to attend a planning session called a simulation. This is used to calculate the correct radiation dose and map the treatment area with both the radiation oncologist and radiation therapist. To ensure your head is in the correct position for each and every treatment, a mold of your face will be created using a grid-like therm…
During The Procedure
- On the day of the procedure, arrive at least 15 minutes beforehand to register and settle in. PCI is typically overseen by the radiation therapist with the aid of a radiology nurse.
Follow-Up
- Because prophylactic cranial radiation is preventive, the only measure of success is the absence of brain metastases on imaging studies. Your oncologist will schedule routine CT, MRI, or positron emission tomography (PET)scans to monitor for any signs of metastasis, not only in the brain but also in other organs and your bones. Your healthcare provider will also monitor for any neurocog…
What Is PCI?
- PCI involves delivering radiation to the brain. A machine sends this radiation in doses stronger than normal x-rays.
