Breast Preservation in Stage I/II Breast Cancer Patients

There are a number of effective treatments for Stage I/II breast cancer, including surgery and radiation therapy. But many patients seek options that allow them to preserve their breast while eliminating the cancer.

The National Cancer Institute surveyed women who had undergone breast-conserving treatment – which consisted of a lumpectomy and external radiation therapy – and 90 percent reported that their cosmetic result was good to excellent. In the same interviews, 98 percent of women stated they would still choose to undergo lumpectomy + radiation therapy if they had to choose again between that and a mastectomy.

Prominent clinical studies have shown that external radiation therapy, such as that offered by the TrueBeam STx system in combination with a lumpectomy is a viable alternative to major surgery required during a mastectomy to address Stage I/II breast cancer. In six major trials around that world, results demonstrated that mastectomy offers no benefit over breast conservation treatment, both in regard to cure and local-regional control of the cancer. With lumpectomy alone, the National Surgical Adjuvant Breast and Bowel Project (NASBP) reported that 40 percent of patients may see their breast cancer return within 10 years after treatment. However, the six trials reported that, overall, 7 percent of patients had a recurrence of cancer in their chest wall and regional node rafter mastectomy, while 8 percent had a similar recurrence after breast conservation treatment using a lumpectomy and radiation therapy.

Taking into consideration the survey of patients and results of these studies, the National Institutes of Health has noted that “breast conservation treatment is an appropriate method of primary therapy for the majority of women with Stage I/II breast cancer, and is preferable because it provides survival equivalent to total mastectomy and axillary node dissection, while preserving the breast.”

There are a number of number of ways radiation therapy can be delivered in breast preserving treatment:

  • External beam, which requires daily radiation treatments over the course of several weeks.
  • High-dose rate (HDR) brachytherapy, which involves an invasive procedure to insert radioactive seeds directly into the tumor.
  • Hypofractionated radiation therapy, another form of external beam radiation delivered via stereotactic body radiation therapy (SBRT), in which tumors are targeted precisely with high doses of radiation over the course of no more than five days.

In studies comparing these three methods, hypofractionated radiation therapy via SBRT delivers results that compare favorably to the longer courses of whole breast daily external beam radiation and the invasive HDR implants.

Radiation Oncologists of Central Arizona (ROCA) at the Phoenix CyberKnife Center have the most advanced SBRT treatment technologies available: the CyberKnife System and TrueBeam STx Radiotherapy System. Led by Medical Director Dr. John Kresl, a pioneer in SBRT, the Phoenix CyberKnife Center offers the widest range of cutting-edge breast cancer treatments, delivered by the most skilled and highly trained nationally recognized and board-certified radiation oncologists.

What Are My Options?

Surgery

The main treatment for breast cancer is surgery. This is often followed by radiation therapy. Some patients will also need chemotherapy and/or hormone blocking therapy.

  • Breast conserving surgery is surgical removal of only the cancerous tissue. This operation is called a lumpectomy and is usually followed by radiation.
  • Mastectomy is surgical removal of the breast.
    • Both surgeries may be done in combination with tests that check the lymph nodes near the breast for cancer.
  • Radiation therapy involves a radiation oncologist delivering radiation to the breast to destroy cancer cells. Radiation therapy works within cancer cells to make them unable to multiply. When these cells die, the body naturally eliminates them. Healthy tissue is able to repair itself in a way cancer cells cannot.
  • Chemotherapy is medication prescribed by a medical oncologist to destroy cancer cells that may have traveled elsewhere in the body.
  • Hormonal therapy is medication prescribed by a medical oncologist to block the effects of hormones that may be helping your tumor grow.

External Beam Radiation Therapy

Painless radiation treatments are delivered in a series of sessions Monday through Friday, for five to eight weeks. Each treatment lasts less than 30 minutes.

  • The usual course of radiation treats only the breast, although you may need to have nearby lymph node areas treated also.
  • 3-dimensional conformal radiotherapy (3D-CRT) combines multiple radiation treatment fields to deliver very precise doses of radiation to the breast and spare surrounding normal tissue.

Side effects can include fatigue, skin irritation similar to a moderate sunburn, and mild to moderate breast swelling. These changes are temporary and can be treated by skin creams and/or medications. Tell your radiation oncologist or nurse about any discomfort you may feel.

Accelerated Partial Breast Irradiation

External beam radiation therapy over several weeks is the standard of care. In national clinical trials, doctors are studying if accelerated partial breast irradiation (or APBI) — where radiation is delivered to only part of the breast over four to five days — works as well. These techniques are only available in a few clinics and then only to a select group of patients.

  • Breast brachytherapy involves placing flexible plastic tubes called catheters or a balloon into the breast. Twice a day for five days, the catheters or the balloon are connected to a brachytherapy machine, also called a high dose rate afterloader. Your radiation oncologist then directs a special computer to guide a small, radioactive seed into the breast tissue near where the tumor was removed. The radiation is left in place for several minutes. After the end of the five days, the catheters or balloon are removed.
  • 3-D conformal partial breast irradiation is where only part of the breast receives external beam radiation.
  • Intra-operative radiation therapy (IORT) involves doctors delivering radiation to the breast during surgery.

The long-term results of these techniques are still being studied. Talk with your radiation oncologist for more information.

After Mastectomy Radiation

After a mastectomy, your doctor may suggest radiation therapy for the chest wall and nearby lymph node areas.

  • Whether or not radiation therapy should be used after removal of the breast depends on several factors. These factors include the number of lymph nodes involved, tumor size, and whether or not cancer cells were found near the edge of the tissue that was removed.

Many patients who have a mastectomy can safely skip radiation therapy. Ask your doctor for more information.

ABOUT BREAST CANCER

Breast Cancer Statistics

Breast cancer is the most common type of cancer in American women, according to the American Cancer Society.

  • This year nearly 213,000 women and 1,700 men will learn they have breast cancer.
  • Another 62,000 women will learn they have noninvasive (also called in situ) breast cancer.
  • Nearly 41,000 women and 500 men will die from breast cancer this year.
  • Breast cancer can often be cured. About 80 percent of all patients with breast cancer are free of the disease 10 years after their diagnosis.

Risk Factors for Breast Cancer

Many women who develop breast cancer do not have known risk factors. Patient qualities that may increase the risk of developing the disease include:

  • Age is the biggest risk factor. More than 75 percent of women diagnosed with breast cancer are over age 50.
  • Family history of breast cancer in your mother or sister.
  • Early onset of periods.
  • Having children later in life, or not at all.
  • Hormone replacement therapy with estrogen and progesterone.

Being physically active, keeping a healthy weight, breast feeding and limiting alcohol intake may lower your risk for developing breast cancer.

Diagnosing Breast Cancer

Many breast tumors are found by a breast X-ray study called a mammogram. At age 40, women should begin having regular mammograms. If you have a family history of the disease or other risk factors, ask your healthcare provider about earlier screening.

  • If you notice a lump in the breast or underarm, have it checked by a doctor. Breast swelling, skin discoloration, dimpling of the skin or nipple discharge should also be checked.
  • In addition to a mammogram, your doctor may also recommend ultrasound or MRI scans.
  • In some cases, a biopsy to see if you have breast cancer will be done if your mammogram is abnormal or you have a lump. Sometimes a small needle will be used to remove tissue from the lump and look at it under a microscope. Sometimes it is better to have a surgeon remove the entire lump to be sure about the diagnosis.
