What is the purpose of this trial?

This trial tests a new approach for treating metastatic non-small cell lung cancer (NSCLC). It compares standard treatments with an experimental technique called stereotactic ablative radiotherapy (SABR), which targets cancer spots with high doses of radiation while continuing current drug treatments. Suitable participants are those with this specific lung cancer, having 1-5 cancer spots outside the brain, and who have not responded to ongoing drug treatment. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial does not require you to stop taking your current medications. In fact, participants will continue their current systemic therapy while receiving the trial treatment.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that SABR (Stereotactic Ablative Radiotherapy) is usually well-tolerated by patients. Studies have found that combining SABR with treatments like chemotherapy or immunotherapy is generally safe, with most people not experiencing severe side effects.

One study found that using SABR with the drug durvalumab resulted in manageable side effects. Another report noted that patients with early-stage lung cancer treated with SABR did not experience serious short-term side effects, and their survival rates were promising. This suggests that SABR could be a safe option for treating certain types of lung cancer.

Overall, while no treatment is without risks, evidence suggests that SABR is generally safe for people with lung cancer. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about SABR (Stereotactic Ablative Radiotherapy) for lung cancer because it offers a precise and targeted approach to treating tumors. Unlike traditional radiotherapy, which can affect surrounding healthy tissue, SABR delivers high doses of radiation directly to the cancerous lesions with pinpoint accuracy. This means fewer side effects and potential for better outcomes. Additionally, for patients with oligoprogressive disease, SABR can be combined with ongoing systemic therapies, providing a more comprehensive treatment strategy that might improve survival rates and quality of life.

What evidence suggests that SABR might be an effective treatment for metastatic non small cell lung cancer?

Research shows that stereotactic ablative radiotherapy (SABR) could benefit lung cancer patients. In this trial, some participants will receive SABR, which earlier studies have found to be safe and effective for certain lung cancers, such as stage I metachronous lung cancer. Specifically, patients who received SABR with chemotherapy showed good survival rates: 80.5% were alive after three years, and 46% after five years. The treatment has a low rate of side effects in the first 90 days, with only 3.8% of patients experiencing negative effects and 1.7% passing away from any cause. This evidence suggests that SABR could be a good option for patients with specific lung cancer conditions. Meanwhile, other participants in this trial will receive standard care treatments, which may include systemic therapy or supportive care. ^{1 5 6 7 8}

Published Research Related to This Trial

Stereotactic ablative radiation therapy (SABR) for lung oligometastases shows promising safety and efficacy, with a 24-month overall survival rate of 74.6% and minimal toxicity, as only one significant adverse event was reported among 77 patients studied over an average follow-up of 22 months.

Colorectal metastases exhibited a notably higher local failure rate compared to other types of tumors, suggesting they may be more resistant to SABR, indicating a need for potential dose escalation strategies for these patients.

Stereotactic body radiation therapy (SBRT) is a preferred treatment for early-stage non-small cell lung cancer (NSCLC) patients who cannot undergo surgery, but accurate lymph node staging is crucial for optimal patient selection.

Current staging methods like PET/CT and EBUS have limited sensitivity in detecting lymph node metastases, which can lead to undetected cancer spread and poorer outcomes; thus, invasive staging procedures are often necessary to improve detection and potentially enhance survival with adjuvant therapies.

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.

The introduction of stereotactic ablative body radiotherapy (SABR) for stage I non-small-cell lung cancer (NSCLC) at a Scottish cancer center has led to improved median survival rates, increasing from 32.5 months before SABR was available to 48.8 months after its establishment.

SABR has not only improved survival outcomes but also increased the proportion of patients receiving radical therapy, particularly among younger and healthier patients, indicating its effectiveness as a treatment option.

In a study of 102 patients treated with stereotactic ablative radiation therapy (SABR) for early-stage non-small-cell lung cancer, a significant correlation was found between higher Biological Equivalent Doses (BED) over 300 Gy and the development of radiological changes such as organizing pneumonia and lung affectation over a 2-year follow-up.

Radiological changes were more pronounced in patients receiving BEDs greater than 300 Gy to healthy lung volumes of at least 30 cc, suggesting that these findings could inform future radiotherapy dose constraints to minimize pulmonary toxicity.

In a study of 39 patients with 45 lung lesions treated with stereotactic ablative body radiotherapy (SBRT), local progression-free survival rates were high, with 90.5% at 1 year and 80.5% at 2 years, indicating effective tumor control.

The treatment was well-tolerated with only mild acute side effects, suggesting that the moderate dose schedules of 35 Gy (5 fractions) or 37.5 Gy (3 fractions) are safe and effective for managing non-small cell lung cancer and metastases.

In a multicenter phase 3 trial involving 101 patients with inoperable stage 1 non-small-cell lung cancer, stereotactic ablative body radiotherapy (SABR) demonstrated significantly better local control compared to standard radiotherapy, with a 68% reduction in the risk of local treatment failure (hazard ratio 0.32).

SABR was associated with a similar safety profile to standard radiotherapy, showing no increase in major toxicity, making it a preferred treatment option for patients with this type of lung cancer.
