Prophalactic Boniva

Wow! I was just on here looking to see if anyone else was getting the boniva. My onc said he is watching a study on this and wanted me to take it. I was diagnosed in Oct 2004 -close to your diagnosis and ER+. I took the boniva twice and I think I had more indigestion than I ever did before. I am going to take it again tomorrow and cut out coffee and orange juice for the day and see if that changes anything. Other than that I haven't noticed anything.

they want to put me on a study with Bisphosphonates as adjuvent therapy for primary breast cancer even though after surgery I am cancer free- I had chemo- rads is in feb- herceptin I m on till Oct 2009.

i would be on this pill for 3 years! It would be arm 1- Zoledronic acid IV every month for 6 months then every 3 months for 30 months! side effects Likely are fever- nausea- constipation- shortness of breath- low red blood cell counts causing fatigue or pale face- loss of appetite- muscle or bone pain.

2nd arm is a pill clodronate- for 3 years- likely side effects are nausea

3rd arm is ibandronate- likely side effects are  diarrhea - pain in arms legs-upset stomach- back pain

allergic reactions can be swelling of mouth or throat- and irregular heart beat

This Bisphosphomates- is supposed to have strong effects on the bones shown to strengthen bones- experimental study to help prevent cancer from spreading to the bones or other parts of the body!

I don't know if I want this study...I think Boniva alone I would try.

Sherri --I am getting Zometa infusions every six months.  My oncologist thinks its a good idea but the only way the insurance will pay is not because I had breast cancer but because I have Osteopenia........

I have had no side effects from the Zometa  except dry eyes and membranes. 

I had also taken Boniva, and Fosamax previously, I was doubled over with stomach pain the days I took either med - (but I have GERD anyway and take PPI's) dry eyes were an issue there as well.

Bone drug helped stave off breast cancer

CHICAGO (Reuters) - A drug used to strengthen the bones of women with breast cancer helped cut the risk of the cancer returning by 36 percent, European researchers said on Saturday,

They said Zometa, sold by Swiss drug giant Novartis AG, helped women with early-stage breast cancer who were already taking hormone therapy to reduce their cancer risk.

The finding comes from the first large-scale study to show a drug in the class known as bisphosphonates can reduce the risk that cancer will come back.

"I'm convinced it's going to change the landscape," said Dr. Michael Gnant of the University of Vienna, who presented his findings at a meeting of the American Society of Clinical Oncology in Chicago.

"In these patients, I would expect it is going to be pretty much the standard of care pretty soon," Gnant said in a telephone interview.

Zometa, known generically as zoledronic acid, is usually prescribed to fortify the bones of breast cancer patients whose tumors have spread to the bone. Breast and other cancers commonly spread to the bone and patients can be crippled by the pain and fractures that result.

Gnant and colleagues studied 1,803 premenopausal women who were taking a synthetic hormone to shut down their ovaries, a practice more common in Europe than in the United States, where such women often get chemotherapy.

"The purpose is to reduce the estrogen levels that circulate in the body. That is what is fueling the cancer," Gnant said.

Women in the study then were given one of two types of anti-estrogen drugs -- tamoxifen and AstraZeneca's newer estrogen-blocker anastrozole or Arimidex.

Arimidex is typically only given to post menopausal women, but the ovarian suppression therapy in effect made women in the study post-menopausal and the researchers wanted to see if this approach would have a benefit.

Researchers also gave the Zometa to prevent bone loss in these younger women. But the bisphosphonate appears to have interfered with the cancer as well, something that has been suggested in smaller studies.

"They can act as anti-cancer drugs. This is the first trial to show they actually do," Gnant said.

The way Zometa reduces cancer risk is not clear. It may be inhibiting cancer cell growth or it may be preventing cancer cells from sticking to the targeted organ. It also could be several things at once, Gnant said.

The American Society of Clinical Oncology's Dr. Julie Gralow of the University of Washington said the findings do not easily translate to breast cancer care in the United States, where most women with early stage breast cancer undergo chemotherapy.

Nevertheless, the drug had very few side effects, and doctors will likely try it. "I think the U.S. will use it," she said in an interview.

Larger trials are under way that will give more evidence on the benefits of such bone drugs in inhibiting cancer. But Gralow said doctors likely will not wait before they start recommending the drug.

"It's a pretty benign therapy for reducing recurrences," she said.

Bone drug helped stave off breast cancer

Zometa (chemical name: zoledronic acid) is a medicine used to strengthen bones in women diagnosed with breast cancer that has spread to the bone. Zometa can reduce bone pain and the risk of fractures. The study reviewed here suggests that Zometa also may lower the risk of early-stage breast cancer coming back.

More than 1,800 premenopausal women being treated for hormone-receptor-positive, early-stage breast cancer got either tamoxifen or Arimidex (chemical name: anastrozole) after surgery and treatment (either medicine or more surgery) to shut down the ovaries. Both tamoxifen and Arimidex are hormonal therapy medicines. About half of the women also got Zometa along with the hormonal therapy medicine. Zometa was given intravenously every 6 months, for a total of 3 years.

Women who got Zometa with the hormonal therapy medicine were 36% less likely to have the breast cancer come back 5 years after treatment than women who got only hormonal therapy medicine:

    * 6% of the women who got Zometa died or had the breast cancer come back 5 years later
    * 9% of the women who didn't get Zometa died or had the breast cancer come back 5 years later

More than 90% of the women in this study didn't have the breast cancer come back 5 years after treatment, whether or not Zometa was part of the treatment plan.

Estrogen can tell hormone-receptor-positive breast cancers to grow. So many premenopausal women diagnosed with hormone-receptor-positive breast cancer either will have their ovaries removed or take medicine after surgery to shut down their ovaries to lower estrogen levels and reduce the risk of the breast cancer coming back. To limit the effects of any remaining estrogen, these women also often take hormonal therapy medicine.

Tamoxifen, which blocks the effect of estrogen on breast cancer cells, often is given to premenopausal women. In this study some of the women were treated with tamoxifen while other women got the aromatase inhibitor Arimidex. Aromatase inhibitors, which block the production of estrogen, usually are given only to post-menopausal women. This study's use of Arimidex in premenopausal women was unusual.

Premenopausal women who take medicines that shut down their ovaries and hormonal therapy medicines after surgery essentially go through menopause because of treatment. This treatment approach dramatically lowers the risk of the breast cancer coming back, but bone loss or weakening (osteoporosis) can be a side effect. So also giving these women a bone-strengthening medicine makes sense. This research suggests that if the bone-strengthening medicine is Zometa, the risk of the cancer coming back also could be lower.

Zometa belongs to a group of medicines called bisphosphonates. All of the bisphosphonates help build bone strength. Other bisphosphonates are Fosamax (chemical name: alendronate), Actonel (chemical name: risedronate), Aredia (chemical name: pamidronate), and Bonefos (chemical name: clodronate).

Fosamax and Actonel are taken by mouth and are used to treat osteoporosis. Zometa and Aredia (given intravenously), and Bonefos (taken by mouth), generally have been used only to strengthen bones in women diagnosed with advanced breast cancer that has already spread to the bone. Research has shown that treatment with Zometa and Bonefos might actually slow the spread of breast cancer to the bones.

This is the first research study to show that Zometa, when combined with ovarian shutdown and hormonal therapy, might help lower the risk of breast cancer coming back in premenopausal women diagnosed with early-stage, hormone-receptor-positive breast cancer. Other research is looking at whether Zometa might lower the risk of breast cancer coming back in post-menopausal women diagnosed with early-stage breast cancer.

In rare cases, taking Zometa or another bisphosphonate can cause a very serious side effect called osteonecrosis of the jaw. This happens when some healthy bone cells die off in a way that's not normal. Osteonecrosis of the jaw usually is seen only in people who have had teeth removed or other dental procedures while taking a bisphosphonate. In this study, none of the women who took Zometa developed osteonecrosis of the jaw or any other serious side effects.

It's not clear how Zometa works to help lower the risk of breast cancer coming back. It's also not clear if Zometa will help lower the risk of cancer coming back in premenopausal women getting chemotherapy. This study was done in Europe; chemotherapy isn't used as often in premenopausal women in Europe as it is in the United States. None of the women in this study got chemotherapy. In the United States, many women similar to those in this study would receive chemotherapy. More research is needed to better understand how Zometa should be used as part of a treatment plan for early-stage breast cancer.

If you're being treated for breast cancer, you might want to ask your doctor about your bone health and bone-strengthening medicines. A bone-strengthening medicine may make sense for you during and after breast cancer treatment.


 

My sister is on Boniva for osteoporosis (thank G-d she doesn't have bc). She told me she has no side effects whatsoever from the Boniva.

Best of luck.

I am taking fasomax once a week for my bones instead of Boniva.  Anyone know if fasomax will do the same in preventing bone mets as Boniva?  Thanks.

According to my Onc, all of the bisphosphonates will work the same. She actually gave me an Rx for Boniva to use if my insurance declined the Zometa, as she said it wasn't worth paying out of pocket for it, when Boniva works the same and is much cheaper. She did feel that oral bisphosphonates had more gastro SE's, and of course you have to take the pill every wek, and do all sorts of things after taking it whereas Zometa is a quick IV.

There is a study ongoing that is comparing three different bisphosphonates, so there should be more answers at some point. 

Do you take any calcium and vitamin d3 supplements for osteopenia and osteoporosis and how much dose?

does your doctor recommends specific exercise ?

is boniva for positive estrogen receptors?
