What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to test whether a radiotherapy regimen of 8 GY x 3 days over 5 days (every other day) is as safe (well-tolerated) and effective as 6 Gy x 5 over five consecutive days

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.

Is PBI Radiotherapy safe for breast cancer patients?

Research shows that PBI Radiotherapy is generally safe for breast cancer patients, with studies reporting mild long-term side effects and low immediate toxicity. Most patients experience minimal acute side effects, and the treatment is considered feasible and safe for selected early breast cancer cases.12345

How does PBI Radiotherapy differ from other breast cancer treatments?

PBI Radiotherapy is unique because it targets only the tumor bed with high doses of radiation, unlike traditional whole-breast irradiation that treats the entire breast. This approach can reduce treatment time and potentially minimize side effects, making it a promising option for patients with early-stage breast cancer.13678

What data supports the effectiveness of the treatment PBI Radiotherapy for Breast Cancer?

Research shows that partial breast irradiation (PBI) is effective for early-stage breast cancer, with studies reporting similar local recurrence rates to whole-breast irradiation. PBI can also improve quality of life by reducing treatment time and travel burdens.157910

Are You a Good Fit for This Trial?

This trial is for post-menopausal women with a specific early-stage breast cancer (pT1), who have had the tumor surgically removed with clear margins and no spread to lymph nodes. Women must not have had previous radiation on the same breast or a high proportion of DCIS, which suggests extensive intraductal component.

Inclusion Criteria

My breast cancer has not spread to my lymph nodes.
I am a post-menopausal woman, confirmed by lack of periods, age, or tests.
My breast cancer was removed with clear margins.

Exclusion Criteria

I have had radiation therapy on the same side breast before.
The biopsy shows a large amount of a specific type of abnormal cells in the milk ducts.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

What Are the Treatments Tested in This Trial?

Interventions

  • PBI Radiotherapy 6 Gy
  • PBI Radiotherapy 8 Gy
Trial Overview The study is comparing two different doses of partial breast irradiation (PBI) radiotherapy in treating breast cancer: one group receives 8 Gy over three sessions every other day for five days, while another gets 6 Gy over five consecutive days. The goal is to see if the higher dose given less frequently is as safe and effective.

Published Research Related to This Trial

In a phase II trial involving 73 early-stage breast cancer patients, the external beam partial breast irradiation (PBI) regimen of 35 Gy in 7 daily fractions was found to be well-tolerated, with no Grade 3 toxicity reported and only minor side effects observed.
The treatment demonstrated high efficacy, achieving a 98% local control rate and a 96.7% rate of freedom from distant metastases over a median follow-up of 40 months, indicating it is a safe and effective option for patients aged 60 and older.
