Research Sponsored by Washington University School of Medicine

Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Invasive ductal, lobular, medullary, papillary, colloid (mucinous), tubular histologies, or mixed histologies (lesions ≤ 2 cm) that are estrogen and/or progesterone receptor positive and do not exhibit HER2/neu gene amplification OR ductal carcinoma in situ (lesions ≤ 2 cm) that are estrogen and/or progesterone receptor positive

All radiation therapy must be planned for delivery at BJH or a BJH/Siteman satellite location with specific stipulations

Must not have

Diagnosis of a coexisting medical condition which limits life expectancy to < 2 years

Prior non-hormonal therapy for the present breast cancer, including radiation therapy or chemotherapy

Timeline

Screening 3 weeks

Treatment Varies

Follow Up at 5 years

Summary

This trial will compare the effectiveness of two types of radiation therapy for treating early stage breast cancer.

Who is the study for?

This trial is for postmenopausal women over 50 with early-stage breast cancer (Stage 0 or I) that's hormone receptor-positive and HER2/neu gene negative. Candidates must have had a partial mastectomy with clear margins, no positive lymph nodes, and not received prior non-hormonal therapy for the current cancer. They should be in good health without life-limiting conditions.

What is being tested?

The study compares two radiation therapies after breast-conserving surgery: one single fraction vs. five fractions of accelerated partial breast irradiation (APBI). It aims to assess which method better controls cancer, has fewer complications, yields better cosmetic results, and improves quality of life.

What are the potential side effects?

Potential side effects from APBI may include skin changes like redness or irritation, fatigue, discomfort at the treatment site, swelling or firmness in the treated area of the breast, and rare risks such as rib fracture or secondary cancers.

Eligibility Criteria

Select...

My radiation therapy will be done at BJH or its specific locations.

Select...

I am postmenopausal.

Select...

My breast cancer has not spread to my underarm lymph nodes, confirmed by tests.

Select...

My breast cancer was early stage (0 or I) and treated with a lumpectomy.

Select...

My breast surgery removed all the cancer that could be seen.

Select...

I was 50 years or older when my condition was diagnosed.

Exclusion Criteria

You may be eligible for the trial if you check “No” for criteria below:

Select...

I have had treatments like radiation or chemotherapy for my current breast cancer.

Select...

My surgery showed cancer cells at the edge of the removed tissue.

Select...

My cancer affects my skin.

Select...

I have Paget's disease of the nipple.

Select...

I have suspicious lymph nodes near my collarbone or breastbone that have been tested and are not cancerous.

Select...

My cancer has spread to distant parts of my body.

Select...

My breast cancer is not the common type but rather a rare form like sarcoma or lymphoma.

Select...

I have multiple tumors in one breast, confirmed not cancerous by biopsy if there were suspicious areas.

Select...

My cancer has spread to the lymph nodes under my arm on the same side as my breast cancer.
