Advanced Radiation Therapy for Lung Cancer

Lung cancer is typically classified into:

• Non-Small Cell Lung Cancer (NSCLC): The most common type, often treated with a combination of surgery, radiation, and/or chemotherapy.
• Small Cell Lung Cancer (SCLC): A more aggressive form that usually responds initially to chemotherapy and radiation.

Early-stage lung cancer may not cause noticeable symptoms. When present, symptoms can include:

• Persistent cough
• Shortness of breath
• Chest pain
• Coughing up blood
• Fatigue and weight loss
• Recurrent pneumonia or bronchitis

Early detection through screening (especially for high-risk patients) and diagnostic imaging is critical.

If lung cancer is suspected, the diagnostic process may include:

• Imaging tests: Chest X-ray, CT scan, PET scan
• Biopsy: Tissue samples obtained through bronchoscopy, needle aspiration, or surgical techniques
• Molecular testing: Helps determine appropriate targeted therapy options

Staging determines the extent of the cancer and guides treatment decisions.

We utilize state-of-the-art radiation technologies to maximize effectiveness and minimize side effects:

Stereotactic Body Radiation Therapy (SBRT)

Also known as “Cyberknife” or ultra-hypofractionated therapy, SBRT delivers high-dose radiation to early-stage or inoperable lung tumors with extreme precision—often in just a few treatments. SBRT is a non-surgical alternative that can yield excellent outcomes.

IG-VMAT (Image-Guided Volumetric Modulated Arc Therapy)

This “super-IMRT” technique combines:

• IGRT: Image-guided radiation for sub-millimeter accuracy
• VMAT: Volumetric arc therapy that delivers radiation in a continuous, dynamic arc

Result: Highly conformal treatment in just minutes, sparing nearby healthy tissue and reducing side effects.

Respiratory Gating & 4D Scanning

Lung tumors move with breathing. ARC’s respiratory management technology synchronizes radiation delivery with the patient’s breathing pattern using:

• 4D CT scanning
• Real-time respiratory gating

This ensures precise targeting while protecting healthy lung and heart tissue.

Following staging and multidisciplinary discussion (involving radiation oncologists, thoracic surgeons, pulmonologists, and medical oncologists), a personalized treatment plan is developed.

Radiation therapy may be used:

• As definitive treatment for inoperable tumors
• Before surgery to shrink tumors (neoadjuvant)
• After surgery to eliminate residual cancer cells (adjuvant)
• With chemotherapy for more advanced disease
• Palliatively to relieve symptoms in metastatic cases

Our goal is maximum tumor control with minimum disruption to healthy tissues.

Radiation side effects vary depending on dose, area treated, and individual sensitivity, but may include:

• Fatigue
• Skin irritation
• Cough or shortness of breath
• Inflammation of lung tissue (radiation pneumonitis)
• Rarely, esophageal irritation (difficulty swallowing)

At ARC, our team provides comprehensive side effect management, including:

• Symptom control
• Nutritional support
• Pulmonary function monitoring
• 24/7 physician access during active treatment

Key risk factors:

• Smoking (active or secondhand)
• Radon exposure
• Asbestos exposure
• Air pollution
• Family history or genetic mutations

Quitting smoking significantly reduces risk—even for long-time smokers—and is one of the most effective prevention strategies.

Consultation

Your care at ARC begins with a comprehensive consultation. During this initial visit, you and your family will meet with one of our experienced radiation oncologists to review your diagnosis and medical history. Together, you’ll explore the most appropriate and effective radiation treatment options tailored to your individual needs. The discussion will also include treatment expectations, potential side effects, and available alternatives to ensure you are fully informed and confident in your care plan.

Simulation (Your Treatment Planning Session)

Once radiation is recommended, you’ll begin with a session called a simulation—a detailed planning appointment that lasts about 45–60 minutes.

During this session:

• We help you get into the best position for your treatment, sometimes using a custom mold to ensure you’re positioned the same way every day.
• Tiny, freckle-sized tattoos may be placed on your skin to help us align your body accurately before each treatment.
• A special imaging scan is performed to pinpoint exactly where the cancer is, so we can target it while protecting nearby healthy tissues.

The Planning process (Behind the Scenes)

After your simulation, your care team—which includes your radiation oncologist, medical physicists, and dosimetrists—will work together to create a custom radiation plan just for you. Using advanced 3D computer software, they map out how to deliver the exact amount of radiation to the right place, while minimizing exposure to healthy areas.

This planning process usually takes 1 to 2 weeks, and it results in a detailed “blueprint” that guides your daily treatments.

Daily Radiation Treatments

Radiation is typically given once a day, five days a week for several weeks. Treatments are done using a machine called a linear accelerator, which delivers invisible, high-energy radiation beams to the cancer.

Here’s what you can expect:

• Each visit takes about 10–15 minutes, with most of the time spent getting you into position. The actual treatment only lasts a few minutes.
• You won’t see or feel the radiation, and there’s no pain during treatment.
• The treatment room is spacious and not claustrophobic.
• In some cases (such as prostate treatment), you may be asked to drink water before your appointment to help move the bladder away from the treatment area.
• Most patients feel well enough to drive themselves, go to work, exercise, and continue their daily routines.

Your radiation oncologist will let you know if there are any specific precautions or changes you should make during treatment.

Weekly On-Treatment Physician Review

During your treatment course, you’ll have weekly visits with your radiation oncologist. These short check-ins help us:

• Monitor how you’re feeling
• Check for any side effects
• Adjust medications if needed
• Answer any questions you have

These visits are an important part of your care and help us support you every step of the way.

Completion of Therapy and Follow-Ups

At the end of your treatment, you’ll meet with your radiation oncologist to talk about:

• What to expect in the coming weeks
• How side effects should improve
• Whether any additional treatment or follow-up is needed

Regular follow-up appointments are essential after radiation to monitor your recovery and watch for any signs of recurrence. We’ll be here to support you long after your final treatment.

If you ever have questions or need guidance along the way, don’t hesitate to reach out. Our team is here to help you feel informed, confident, and cared for throughout your journey.
