How Radiation Therapy Works in Lung Cancer Treatment

Radiation therapy is key in lung cancer care. It targets cancer cells with high-energy X-rays, keeping normal tissue safe. Modern techniques focus on harming cancer cells’ DNA. This stops their growth while sparing healthy cells around them.

Mechanism of Action

This approach uses high-energy rays on tumors, causing cell death. It shrinks cancerous growths, improving outcomes. Healthy cells recover faster than cancer cells. So, patients with lung cancer need custom treatment plans.

Types of Radiation Therapy

External Beam Radiation Therapy (EBRT) is commonly used for lung cancer. Patients undergo treatments five days a week for 5 to 7 weeks. Stereotactic Body Radiation Therapy (SBRT) offers high doses in 1 to 5 sessions. Brachytherapy involves radioactive seeds that work over weeks.

TrueBeam™, CyberKnife®, and TomoTherapy® make radiation more precise. They target tumors while protecting healthy tissue. Small cell lung cancer patients might get prophylactic cranial irradiation. This prevents brain cancer. Side effects include skin irritation and fatigue but improve after two months.

Drinking plenty of water helps make treatment more effective. It’s crucial for reducing side effects and boosting energy. Proper hydration supports overall health during cancer treatment. Learn more about hydration’s benefits here.

Types of Radiation Therapy for Lung Cancer

Doctors use different radiation therapy methods for lung cancer. These include external beam radiation therapy (EBRT), brachytherapy, and proton therapy. Knowing about these can help patients choose the right treatment for them.

External Beam Radiation Therapy (EBRT)

External beam radiation therapy (EBRT) is common for lung cancer. It uses powerful radiation beams targeted at the cancer from outside the body. These treatments are quick, painless, and spread over weeks. EBRT aims to attack cancer cells while saving healthy tissues.

Brachytherapy

Brachytherapy targets the cancer more directly. It places radioactive materials into or near the tumor, sometimes with a bronchoscope. This method works well for certain cases, focusing radiation on the tumor to minimize harm to healthy areas.

Proton Therapy

Proton therapy is known for its accuracy. It uses protons instead of X-rays, reducing damage to nearby healthy tissue. This choice is great for complex situations. The benefits of proton therapy for lung cancer are becoming more known, especially for those who need high-dose radiation with fewer side effects.

The Process of Radiation Therapy

The journey of radiation therapy for lung cancer goes through several steps. It begins with a first meeting with the oncologist. Here, the doctor looks at the patient’s health and talks about the treatment paths. This first step is very important as it guides the rest of the therapy journey.

Initial Consultation and Planning

In the first meeting, the oncologist checks medical records and does tests. They look at imaging results too. This helps create a treatment plan just for the patient. The doctor explains how radiation therapy works. They cover why a certain method is chosen, like external beam radiation, brachytherapy, or proton therapy. Patients can ask questions and share concerns. This makes the consultation key to good planning.

Simulation Sessions and Refinement

After talking with the doctor, simulation sessions start. They make sure the patient is in the right spot for treatment using high-tech images. This is critical for fine-tuning the treatment plan. It makes sure the radiation hits its target well. The process often includes taking several images. These create a 3D map of where the tumor is. Patients might get temporary markers. These help keep them in the right position for all treatment sessions.

Delivery of Treatment

When the treatment plan is ready, the therapy begins. It happens over many sessions, usually five days a week, for a few weeks. This schedule helps keep the treatment consistent. It also lets doctors watch for any side effects. The healthcare team looks out for the patient’s health and comfort the whole time. They’re there to offer support. Most of the time, side effects go away a couple of months after finishing treatment.

Radiation Techniques Utilized in Lung Cancer

Various advanced radiation techniques are key in treating lung cancer. They improve treatment and lessen side effects. Knowing about these methods helps doctors plan for each patient.

Stereotactic Body Radiation Therapy (SBRT)

Stereotactic body radiation therapy (SBRT) is an advanced method. It uses high doses of radiation on the cancer in a few sessions. It works well for early lung cancer and when cancer has spread. SBRT focuses on the tumor, protecting healthy tissue and shortening treatment time.

Three-Dimensional Conformal Radiation Therapy (3D-CRT)

Three-dimensional conformal radiation therapy (3D-CRT) uses computers to see the tumor in 3D. It shapes the radiation beams to fit the tumor’s shape. This means the tumor gets a high dose of radiation, and healthy areas get less. This method is effective and widely used in treating lung cancer.

Intensity Modulated Radiation Therapy (IMRT)

Intensity modulated radiation therapy (IMRT) offers even more precision. It adjusts the radiation’s strength based on the tumor’s shape. IMRT is great at targeting the cancer and saving nearby healthy tissue. It focuses on treating effectively while keeping the patient comfortable.

Using Radiation Therapy Before and After Surgery

Radiation therapy is key in treating lung cancer, especially with surgery. It’s used before and after surgery to improve results and cut recurrence risks. This approach can change the tumor and tackle remaining cancer cells, making it crucial for cancer care.

Preoperative Radiation Therapy

Preoperative radiation can make a big difference in surgery results. This method shrinks tumors, making surgery easier. It helps a lot with big tumors or in patients with high surgical risks.

By shrinking the tumor, surgery can more likely remove it completely. Studies also show that preoperative radiation can lead to a better prognosis after surgery.

Postoperative Radiation Therapy

Postoperative radiation aims to kill any left-over cancer cells after surgery. This helps prevent the cancer from coming back. It’s a standard part of surgery for many patients.

This aggressive treatment approach is used when cancer might have spread or if surgical margins are unclear. It aims to increase survival rates and give patients comfort.

Preoperative and postoperative radiation therapies are both crucial in lung cancer treatment. They play big roles in managing tumors both before and after surgery. Adding them to treatment plans shows how lung cancer fight strategies are improving.
