Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment External Beam Radiation Therapy (EBRT) for breast cancer?

External Beam Radiation Therapy (EBRT) has been shown to be effective in treating various cancers, such as prostate cancer, by improving survival rates and reducing cancer recurrence. While this data is specific to prostate cancer, it suggests that EBRT can be a powerful tool in managing cancer, potentially including breast cancer.12345

Is external beam radiation therapy (EBRT) generally safe for humans?

EBRT is generally considered safe, but it can cause side effects like pain flare, which occurs in 16-41% of patients who haven't taken steroids. This information is based on studies involving EBRT for conditions like bone metastases.14678

How does external beam radiation therapy (EBRT) for breast cancer differ from other treatments?

External beam radiation therapy (EBRT) is unique because it is a non-invasive treatment that uses high-energy rays to target and destroy cancer cells in the breast, often as part of breast-conserving therapy. Unlike some other treatments, EBRT can be extended to target additional areas like the supraclavicular fossa and internal mammary chain, providing comprehensive coverage for high-risk patients.1891011

What is the purpose of this trial?

Single-arm, phase 2 study evaluating hypofractionated irradiation of breast and regional nodes in women with breast cancer. Patients will be grouped in 3 surgery-related treatment groups: 1) An intact breast following lumpectomy; 2) plans for loco regional external beam radiotherapy (EBRT) following mastectomy (with or without plans for reconstruction); and 3) plans for locoregional EBRT following mastectomy with reconstruction.Patients will be assessed for lymphedema, arm function, breast or chestwall pain, other EBRT-related adverse events, and, for patients who had a lumpectomy or mastectomy with reconstruction, cosmetic outcome.

Eligibility Criteria

This trial is for women with breast cancer who've had surgery, have healed incisions without infection, and tested ER, PR, HER2 on the tumor. They must understand English consent forms, not be pregnant or breastfeeding, use birth control during the study, and meet specific criteria related to their cancer stage and treatment history.

Inclusion Criteria

My breast cancer is confirmed as invasive adenocarcinoma.
My surgical wound has healed without any infection.
I am not pregnant, as confirmed by a test, and I am not postmenopausal or have not had a hysterectomy.

Exclusion Criteria

I have had breast cancer or DCIS on either side and received radiation therapy.
I have had surgery on the same or opposite side armpit before.
My breast cancer is advanced (T4) or inflammatory.

Treatment Details

Interventions

  • External Beam Radiation Therapy
Trial Overview The study tests hypofractionated irradiation therapy in women post-breast surgery. It's a phase 2 trial where patients are grouped based on their surgical status: after lumpectomy; post-mastectomy with/without reconstruction plans; or post-mastectomy with reconstruction. Outcomes like lymphedema and pain will be monitored.
Participant Groups
1Treatment groups
Experimental Treatment
Group I: Treatment (EBRT)Experimental Treatment3 Interventions
External Beam Radiation Therapy (EBRT). Within 10 weeks after the last breast cancer surgery or the last dose of adjuvant chemotherapy, patients undergo hypofractionated RNI five days a week over 3-4 weeks. The two subgroups are Cohort (A) sentinel lymph node (SLN) and Cohort (B) axillary lymph node (ALN) dissection. They are categorized depending on type of axillary surgery and treatment group. The type of axillary surgery is Sentinel lymph node (SLN) biopsy only vs axillary dissection with or without previous SLN biopsy. The treatment groups are lumpectomy vs mastectomy vs mastectomy/reconstruction.

Findings from Research

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]
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.

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.
