What You Need to Know Before You Apply

What is the purpose of this trial?

This pilot clinical trial studies the effects of stereotactic body radiation therapy followed by surgery in treating patients with stage I-IIIA non-small cell lung cancer. Stereotactic body radiation therapy is a method of radiation that uses imaging to precisely locate a tumor and then deliver very high radiation doses to the tumor site in order to limit normal tissue toxicity or damage.

Do I need to stop my current medications for the trial?

The trial protocol does not specify whether you need to stop taking your current medications. However, it does mention that you cannot receive other cancer treatments while participating, except for certain pre-approved therapies.

Is radiation therapy combined with surgery for lung cancer safe?

Stereotactic Ablative Radiotherapy (SABR), including CyberKnife, is generally safe for treating lung cancer, with high rates of tumor control and acceptable levels of side effects. However, some serious complications have been reported, so strategies to reduce these risks are important. ^{1 2 3 4 5}

How is the treatment Stereotactic Body Radiation Therapy (SABR) unique for lung cancer?

Stereotactic Body Radiation Therapy (SABR) is unique for lung cancer because it delivers high doses of radiation with precision over a few sessions, making it suitable for patients who cannot undergo surgery. The CyberKnife system used in SABR is particularly effective for lung tumors that move with breathing, offering high local tumor control with minimal side effects. ^{1 2 3 6 7}

What data supports the effectiveness of the treatment Radiation Therapy + Surgery for Lung Cancer?

Research shows that Stereotactic Ablative Radiotherapy (SABR), especially using the CyberKnife system, is effective for treating early-stage non-small cell lung cancer, offering high rates of local tumor control with minimal side effects. This treatment is particularly beneficial for patients who cannot undergo surgery, providing a precise and non-invasive option. ^{1 2 3 6 8}

What Are the Treatments Tested in This Trial?

Interventions

• Stereotactic Body Radiation Therapy
• Thoracic Surgical Procedure

Trial Overview The trial tests stereotactic body radiation therapy followed by surgery in treating early-stage lung cancer. It aims to see how precisely targeting high-dose radiation at the tumor before surgical removal affects outcomes while minimizing damage to healthy tissue.

How Is the Trial Designed?

Group I: Study 3 (lowest- or higher-dose of SBRT, surgery) Experimental Treatment 4 Interventions

Patients with stage IIIA NSCLC in the any lung location undergo lowest- or higher-dose of Stereotactic Body Radiation Therapy over a single treatment fraction on day 1. Patients then undergo thoracic surgery on day 28.

Group II: Study 2 (lowest-dose of SBRT, surgery) Experimental Treatment 4 Interventions

Patients with stage I or II NSCLC in the central lung undergo lowest-dose of Stereotactic Body Radiation Therapy over a single treatment fraction on day 1. Patients then undergo thoracic surgery on day 28.

Group III: Study 1 (highest-dose of SBRT, surgery) Experimental Treatment 4 Interventions

Patients with stage I or II NSCLC in the peripheral lung undergo highest-dose of Stereotactic Body Radiation Therapy over a single treatment fraction on day 1. Patients then undergo thoracic surgery on day 28.

Published Research Related to This Trial

Stereotactic ablative radiotherapy (SABR) is an effective treatment for early-stage non-small cell lung cancer, especially for patients who cannot undergo surgery, showing high local tumor control rates with manageable side effects.

The CyberKnife system is particularly advantageous for SABR in lung tumors due to its ability to accurately target moving tumors during breathing, enhancing treatment precision.

CyberKnife stereotactic ablative radiotherapy for lung tumors. Gibbs, IC., Loo, BW.[2022]

In a study of 100 patients with early-stage non-small cell lung cancer (NSCLC) treated with stereotactic ablative body radiotherapy (SABR), the 1-, 2-, and 3-year local control rates were 100%, 93.55%, and 84.33%, respectively, indicating high efficacy in tumor control.

The treatment was associated with low toxicity, with only 2% of patients experiencing Grade-3 side effects, suggesting that SABR is a safe option for patients who are inoperable or refuse surgery.

Definitive Treatment of Early-Stage Non-Small Cell Lung Cancer with Stereotactic Ablative Body Radiotherapy in a Community Cancer Center Setting. Heal, C., Ding, W., Lamond, J., et al.[2020]

Stereotactic ablative radiotherapy (SABR) using Cyberknife demonstrated high effectiveness in treating stage I non-small-cell lung cancer, with 2-year local control, progression-free, and overall survival rates of 91.9%, 61.7%, and 84.8%, respectively, based on a study of 153 patients.

The treatment was generally safe, with only 8.1% of patients experiencing severe toxicities, including one case of grade 5 radiation pneumonitis, indicating that while SABR is effective, careful monitoring for side effects is necessary.

Stereotactic Ablative Radiotherapy Using CyberKnife for Stage I Non-small-cell Lung Cancer: A Retrospective Analysis. Hayashi, K., Suzuki, O., Shiomi, H., et al.[2022]

Stereotactic ablative radiotherapy (SABR) is an effective treatment for early-stage non-small cell lung cancers (NSCLCs) that are medically inoperable, providing local control and toxicity levels comparable to surgical resection.

SABR is gaining interest as a noninvasive treatment option for patients with borderline resectable lung cancers, although further randomized studies are needed to evaluate its survival benefits in operable patients.

Stereotactic ablative radiotherapy (SABR) for non-small cell lung cancer. Iyengar, P., Westover, K., Timmerman, RD.[2013]

Stereotactic ablative radiation therapy (SABR) was found to be effective for treating pulmonary metastases, with a median follow-up of 23 months showing improved overall survival (OS) for patients with 3 or fewer metastases compared to those with more (74.2% vs. 59.3% at 24 months).

Patients with less responsive primary tumors (like adrenal or pancreatic cancers) had higher local failure rates, suggesting that higher doses of SABR or surgical options may be necessary for these cases to improve treatment outcomes.

Stereotactic ablative radiotherapy (SABR) has rapidly expanded in clinical use for treating various primary and metastatic tumors, demonstrating promising results in tumor control.

Despite its effectiveness, SABR can lead to serious complications, highlighting the need for strategies to reduce these risks and improve the safety of the treatment.

The iSABR trial demonstrated that individualized stereotactic ablative radiotherapy (SABR) for lung tumors resulted in high local control rates, with freedom from local recurrence at 1 year ranging from 94% to 97% across different patient groups.

The trial showed a low incidence of severe toxic effects (only 5%), indicating that personalized dosing strategies can minimize risks while maintaining effective treatment outcomes.
