What You Need to Know Before You Apply

What is the purpose of this trial?

This phase II trial studies the side effects and best dose of radiation therapy and to see how well it works in treating patients with cancer that has spread to other places in the body (metastatic) or has increased in size after being treated with immunotherapy. Giving radiation therapy may help to control the cancer after the disease has gotten worse after receiving immunotherapy in patients with cancer that has spread to the other places in the body.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you may continue with maintenance immunotherapy while receiving radiation.

Is radiation therapy generally safe for humans?

Radiation therapy, including External Beam Radiation Therapy (EBRT), is generally considered safe for humans, but it can cause side effects like pain flare, which occurs in 16-41% of patients who haven't taken steroids. This treatment has been used for various conditions, and while it is effective, patients should be aware of potential side effects. ^{1 2 3 4 5}

How is external beam radiation therapy (EBRT) unique for treating metastatic cancer?

External beam radiation therapy (EBRT) is unique because it is a non-invasive treatment that uses high-energy rays to target and relieve pain from bone metastases, making it a key option for managing symptoms in metastatic cancer patients. ^{2 6 7 8 9}

What data supports the effectiveness of this treatment for metastatic cancer?

Research shows that external beam radiation therapy (EBRT) is effective in treating bone metastases, providing pain relief and improving quality of life for patients with various cancers. Additionally, EBRT has been used successfully for prostate cancer, improving survival rates and managing symptoms. ^{2 7 10 11 12}

Published Research Related to This Trial

External beam radiotherapy (EBRT) is an effective treatment for relieving symptoms caused by bone metastases in prostate cancer patients.

This review specifically compares the effectiveness of single fraction radiotherapy to multiple fraction radiotherapy, highlighting the need for further analysis on which approach may provide better outcomes for patients.

Single fraction radiotherapy versus multiple fraction radiotherapy for bone metastases in prostate cancer patients: comparative effectiveness. Yoon, F., Morton, GC.[2020]

The American Society for Radiation Oncology has released updated, evidence-based guidelines for using external-beam radiotherapy (EBRT) to treat painful bone metastases, emphasizing the importance of these guidelines in improving patient care and quality indices at radiotherapy centers.

Recent findings highlight the need for proper management of pain flare reactions that can occur after starting radiotherapy, as well as the validation of the EORTC QLQ-BM22 quality-of-life module for assessing patient well-being in clinical trials.

External-beam radiotherapy (EBRT) has been effectively used for over 30 years to treat prostate adenocarcinoma, demonstrating significant improvements in cause-specific survival and freedom from PSA progression.

Recent advancements in radiation techniques have enhanced the safety and efficacy of EBRT, making it a viable treatment option for early-stage, locally advanced, and metastatic prostate cancer, while managing side effects effectively.

In a study of 15,494 newly diagnosed metastatic prostate cancer patients, external beam radiation therapy (EBRT) did not improve overall mortality for the entire group, but it significantly reduced mortality in M1a patients and M1b patients with PSA levels of 10.0 ng/ml or lower.

The findings suggest that only a smaller subset of North American metastatic prostate cancer patients benefit from EBRT compared to previous reports from European studies, highlighting the need for further validation in North America.

In a study of 29 patients with oligometastatic hormone-sensitive prostate cancer treated with external beam radiation therapy (EBRT) and androgen deprivation therapy, the median overall survival was 9.7 years, indicating promising long-term outcomes for this treatment approach.

Patients with de novo metastases experienced significantly better progression-free survival (2.0 years) compared to those with oligorecurrent disease (1.8 years), suggesting that the timing and nature of metastases may influence treatment effectiveness.

In a study of 32 patients receiving External Beam Radiotherapy (EBRT) for bone metastases, 41% experienced a pain flare, which is defined as a significant increase in pain or analgesia intake, with a median duration of 3 days.

The incidence and duration of pain flare observed in this study align with findings from international studies, indicating that pain flare is a common side effect of EBRT for bone metastases.

An investigation into the incidence of pain flare in patients undergoing radiotherapy for symptomatic bone metastases. Goldfinch, R., White, N.[2018]

Patients with asymptomatic bone metastases who received external beam radiation therapy (EBRT) experienced a significant delay in the onset of moderate-to-severe pain and skeletal-related events (SREs), with a median time of 81 months compared to 25 months for untreated patients (P<0.001).

EBRT was particularly effective in delaying pain and SREs in prostate and lung cancer patients, although it did not show the same benefit for breast cancer patients, and it did not affect overall survival rates.

In a phase 3 trial involving 1532 prostate cancer patients, escalating the dose of external beam radiation therapy (EBRT) from 70.2 Gy to 79.2 Gy did not significantly impact patient-reported outcomes (PROs) such as erectile function and quality of life over 24 months.

Despite the higher radiation dose, there was no significant difference in the rates of erectile dysfunction between the two treatment groups, indicating that higher doses of EBRT may not lead to worse patient experiences in terms of these specific outcomes.

A pilot study involving seven patients found that while traditional education methods for external beam radiation therapy (EBRT) were satisfactory, 86% of participants felt they did not fully capture the treatment experience.

The introduction of a 360-degree virtual reality (VR) video as a supplemental educational tool showed potential benefits, including improved understanding of the treatment process and reduced anxiety, especially when viewed before the first treatment session.

From 2015 to 2017, short-course external-beam radiation therapy (EBRT) for bone metastases increased, while long-course EBRT decreased by 8%, indicating a shift towards more efficient treatment options.

Stereotactic body radiation therapy (SBRT) usage rose to 7% of treatments, showing a growing acceptance of complex techniques, although expenditures for these advanced modalities decreased, suggesting improved cost-effectiveness.

In a study of 31 patients with non-metastatic castration-resistant prostate cancer treated with definitive external-beam radiotherapy (EBRT), the 5-year overall survival rate was 74.6%, indicating that EBRT can lead to favorable long-term survival outcomes.

The treatment resulted in a local relapse-free survival rate of 91% at both 5 and 8 years, suggesting that EBRT is effective in preventing local recurrence of the cancer, although about one-third of patients experienced disease recurrence within 5 years.

Definitive external beam radiotherapy (EBRT) for unresectable soft-tissue sarcomas shows promising 5-year local control rates of 28-73% for photon therapies and 52-69% for particle therapies, based on a systematic review of 29 studies involving 1409 patients.

While doses of 64-66 Gy appear to be safe and effective, higher doses (≥68 Gy) significantly increase the risk of severe adverse events, highlighting the need for careful dose management in treatment planning.
