Brachyterapy for breast cancer treatment

My prognosis is B C satage 1, Onco Test score #13, 9% recurrance. I had a Lumpectomy in January 2010 with negative Margins. Five years ago I had Cosmetic Breast Augmentation Saline Implants.
My Surgeon recommended Radiation. I understand ,that a standard Procedure will be out of consideration, because of Capsular Contracture.Is it BRANCHYTHERAPY  an option in my particular case? Please, advise!

Dear alidi:  Whether or not brachytherapy is an option would need to be discussed with a radiation oncologist.  Without evaluation, it is impossible to speculate on specific treatment options.

This info is from the American Cancer Society Web page, it is only meant for you to know why/when are brachytherapies used in breast cancer issues and how many methods there are. It is always best to discuss procedures with your radiation oncologist.  

Radiation Therapy
Radiation therapy is treatment with high-energy rays or particles that destroy cancer cells. This treatment may be used to kill any cancer cells that remain in the breast, chest wall, or underarm area after breast-conserving surgery. Radiation may also be needed after mastectomy in patients with either a cancer larger than 5 cm in size, or when cancer is found in the lymph nodes.

Radiation therapy can be given in 2 main ways.
1] External beam radiation
This is the most common type of radiation therapy for women with breast cancer. The radiation is focused from a machine outside the body on the area affected by the cancer. The extent of radiation depends on whether a lumpectomy or mastectomy was done and whether or not lymph nodes are involved. If a lumpectomy was done, the entire breast gets radiation, and an extra boost of radiation is given to the area in the breast where the cancer was removed to prevent it from coming back in that area. Depending on the size and extent of the cancer, radiation may include the chest wall and underarm area as well. In some cases, the area treated may also include supraclavicular lymph nodes (nodes above the collarbone) and internal mammary lymph nodes (nodes beneath the breast bone in the center of the chest).

When given after surgery, external radiation therapy is usually not started until the tissues have been able to heal, often a month or longer. If chemotherapy is to be given as well, radiation therapy is usually delayed until chemotherapy is complete.
Before your treatments start, the radiation team will take careful measurements to determine the correct angles for aiming the radiation beams and the proper dose of radiation. They will make some ink marks or small tattoos on your skin that they will use later as a guide to focus the radiation on the right area. You may want to talk to your health care team to find out if these marks will be permanent.

Lotions, powders, deodorants, and antiperspirants can interfere with external beam radiation therapy, so your health care team may tell you not to use them until treatments are complete. External radiation therapy is much like getting an x-ray, but the radiation is more intense. The procedure itself is painless. Each treatment lasts only a few minutes, although the setup time -- getting you into place for treatment -- usually takes longer. The most common way breast radiation is given is 5 days a week (Monday thru Friday) for about 6 weeks.

2] Accelerated breast irradiation: The standard approach of giving external radiation for 5 day a week over many weeks can be inconvenient for many women. Some doctors are now using other schedules, such as giving slightly larger daily doses over only 3 weeks, which seems to work about as well. Giving radiation in larger doses using fewer treatments is known as hypo fractionated radiation therapy. Newer approaches now being studied give radiation over an even shorter period of time. In one approach, larger doses of radiation are given each day, but the course of radiation is shortened to only 5 days. In another approach, known as intra operative radiation therapy (IORT), a single large dose of radiation is given in the operating room right after lumpectomy (before the breast incision is closed).

3] Other forms of accelerated radiation are described below in the section on brachytherapy. It is hoped that these newer approaches may prove to be at least equal to the current, standard breast irradiation, but few studies have been done comparing these new methods directly to standard radiation therapy. It is not known if the newer methods will still be as good as standard radiation after many years. For this reason, many doctors still consider them to be experimental at this time. Women who are interested in these approaches may want to ask their doctor about taking part in clinical trials of accelerated breast irradiation now going on.

3D-conformal radiotherapy: In this technique, the radiation is given with special machines so that it is aimed better at the area where the tumor was. This allows more of the healthy breast to be spared. Treatments are given twice a day for 5 days.

Possible side effects of external radiation: The main short-term side effects of external beam radiation therapy are swelling and heaviness in the breast, sunburn-like skin changes in the treated area, and fatigue. Your health care team may advise you to avoid exposing the treated skin to the sun because it may make the skin changes worse. Changes to the breast tissue and skin usually go away in 6 to 12 months.

In some women, the breast becomes smaller and firmer after radiation therapy. Having radiation may also affect a woman's chances to have breast reconstruction. Radiation therapy of axillary lymph nodes also can cause lymphedema (see the section, "What will happen after treatment for breast cancer?").

In rare cases, radiation therapy may weaken the ribs, which could lead to a fracture. In the past, parts of the lungs and heart were more likely to get some radiation, which could lead to long-term damage of these organs in some women. Modern radiation therapy equipment allows doctors to better focus the radiation beams, so these problems are rare today. A very rare complication of radiation to the breast is the development of another cancer called angiosarcoma (see "What is breast cancer?"). These rare cancers can grow and spread quickly.

4] Brachytherapy
Brachytherapy, also known as internal radiation, is another way to deliver radiation therapy. Instead of aiming radiation beams from outside the body, radioactive seeds or pellets are placed directly into the breast tissue next to the cancer. It is often used as a way to add an extra boost of radiation to the tumor site (along with external radiation to the whole breast), although it may also be used by itself (see below). Tumor size, location, and other factors may limit who can get brachytherapy.

There are different types of brachytherapy.

Intracavitary brachytherapy: This method of brachytherapy consists of a small balloon attached to a thin tube. The deflated balloon is inserted into the space left by the lumpectomy and is filled with a salt water solution. (This can be done at the time of lumpectomy or within several weeks afterward.) The balloon and tube are left in place throughout treatment (with the end of the tube sticking out of the breast). Twice a day a source of radioactivity is placed into the middle of the balloon through the tube and then removed. This is done for 5 days as an outpatient treatment. The balloon is then deflated and removed. This system goes by the brand name, Mammosite®. This type of brachytherapy can also be considered a form of accelerated breast irradiation. Like other forms of accelerated breast irradiation, there are no studies comparing outcomes with this type of radiation directly with standard external beam radiation. It is not known if the long-term outcomes will be as good.

Interstitial brachytherapy: In this approach, several small, hollow tubes called catheters are inserted into the breast around the area of the lumpectomy and are left in place for several days. Radioactive pellets are inserted into the catheters for short periods of time each day and then removed. This method of brachytherapy has been around longer (and has more evidence to support it), but it is not used as much anymore.

While these methods are sometimes used as ways to add a boost of radiation to the tumor site (along with external radiation to the whole breast), they are also being studied in clinical trials as the only source of radiation for women who have had a lumpectomy. In this sense they can also be considered forms of accelerated partial breast irradiation.

Hi; Thanks so much for the very detail and great information, I have an appoiment for
Monday Feb 22 with a Radiation Oncologist, and will discuss my options.Since I have Cosmetic Implants I know Standard Radiation is out of consideration.
Thanks again, God Bless!!

I am glad you found my post detailed, now you know the Brachytherapy alternatives that are available. It is always best to have solid information and then talk to your doctor, I have found it very useful along my various treatments.
I hope you will do fine on the 22nd and that your treatment choices will be the best for you.

Good luck and God Bless.
