Triple-negative breast cancer means that the pathology report has shown the cancer to be estrogen receptor negative, progesterone receptor negative, and HER2 negative.

Results published in Clinical Cancer Research found that women with triple negative breast cancer have an increased risk of metastatic disease and death during the first few years after diagnoses, but not after that time period.

A study was conducted among 1,601 breast cancer patients. One hundred and eighty women (11.2%) had triple negative breast cancer.

The results of the study:

Herceptin (trastuzumab) is a targeted therapy used for treatment of HER2 positive breast cancer. Results of a Phase II clinical trial showed that Herceptin might have a roll in treating patients with HER2 positive advanced bladder cancer.

The researchers conducted the clinical trial to examine the effectiveness of Herceptin along with chemotherapy in a little under fifty patients with advanced bladder cancer. The chemotherapy given with the Herceptin was paclitaxel, carboplatin, and gemcitabine.

This was a small study and research will have to continue to see if this treatment is something that will be put into mainstream use. The study concluded that:

• 11 percent of patients experienced a complete disappearance of detectable cancer.
• 59 percent of patients experienced a partial disappearance of detectable cancer.

Drugs currently in trials for obesity and diabetes may soon be fast-tracked for use in the fight against breast cancer. Typically, it takes many years to research and develop new drugs. But these already-developed drugs, if successful, could reach the market much quicker.

The drugs, believed to work by blocking the enzyme PTP1B, could help breast cancer patients because the enzyme is found in high levels in about 40 percent of these patients.

Studies on mice show blocking production of the enzyme significantly slowed tumor development. In some cases, it stopped the spread of the cancer and it might even stop some tumors from forming.

It's been one year since I began writing for The Cancer Blog. According to statistics generated by this site, I've written 27,381 words and 793 posts. If you've been reading for this entire time, you surely know a lot about me. Not only do my posts reflect current news and issues, but they feature all sorts of personal stuff too. When considered together, my work here reflects just about every piece of my cancer journey, my inner most thoughts, my morals and values, my take on the world. But for those of you who haven't been reading for long, for those who have forgotten how I fit into the cancer puzzle, for those who want a recap, here's a rundown on me: Jacki Donaldson.

I was born and raised in Ohio but have also lived in Nevada, Virginia, and Florida -- my current home. My life always went pretty much according to plan -- I lived happily with my parents and one sister, faithfully attended school, went to college, got married, had two baby boys and a series of good jobs, and had just begun commenting to my family members about how lucky our family was not to have been affected by cancer. It seems just as I spoke this aloud, cancer arrived.

On Tuesday, researchers announced that a three-drug cocktail may help women with HER2-positive breast cancer better than any other drug used on its own. About one quarter of women with breast cancer make up this HER2 category.

Tests on mice revealed using the three drugs along with breast cancer drug tamoxifen helped wipe out tumors altogether. And the tumors did not come back. This is the first time mice were cured of a very aggressive human breast tumor. Incidentally, when a single drug was used, tumors returned within several weeks.

The three wonder drugs used in this study -- all are monoclonal antibodies that precisely target certain aspects of tumors -- are the experimental drug pertuzumab; trastuzumab, also known as Herceptin; and gefitinib, or Iressa.

Published in the Journal of the National Cancer Institute, this study supports the notion that HER2-positive tumors eventually become resistant to one drug and attacking them on several fronts seems to work better.

Breast cancer drug Herceptin has been approved in Europe for use with hormonal therapy for postmenopausal patients with HER2 and hormone receptor positive metastatic disease.

Herceptin, made by Swiss drugmaker Roche Holding AG, is already approved in Europe for early and metastatic HER2-positive breast cancer.

This new approval is based on data from an international late stage clinical trial showing the combination of Herceptin with hormonal therapy doubled the median progression-free survival time.

Twenty to thirty percent of breast cancers over express a protein referred to as the human epidermal growth factor receptor, better known as HER2 over expression.

Herceptin is an agent that is targeted against the HER2 receptor and helps to slow or stop the spread of cancer cells that over express this protein. Unfortunately, some women that do have the over expression of HER2 on their breast cancer cells do not respond to treatment with Herceptin.

The Journal of the National Cancer Institute has published a report that says among breast cancer patients with HER2 over expressing cancer cells, those whose cells also express a receptor called p95HER2 have a poor anti-cancer response rate with Herceptin.

The study included forty seven women with metastatic breast cancer. All were treated with Herceptin. Nine of these patients also expressed the receptor p95HER2.

The results showed that only 11 percent of the women with the p95HER2 expression showed an anti-cancer response to Herceptin. Of the patients who did not express p95HER2 demonstrated a response of 51 percent. The report also showed that laboratory testing of cancer cells that do express p95HER2 demonstrated anti-cancer activity with a drug called Tykerb.

The researchers concluded that patients with HER2-over expressing breast cancer who also express p95HER2 appear to be more resistant to treatment with Herceptin and "may require alternative or additional anti-HER2–targeting strategies." Patients with HER2-over expressing breast cancer may wish to speak with their physician regarding their individual risks and benefits of participating in a clinical trial further evaluating biologic markers that may help predict responses to certain therapies.

It's called triple-negative breast cancer and it manifests itself in the lack of expression of two cell surface proteins -- estrogen and progesterone receptors -- and also the protein HER2.

It's a disease that does not typically respond to treatment with standard chemotherapy drugs and therefore, diagnosis can come with a poor prognosis. But a new study out of Massachusetts General Hospital Cancer Center in Boston indicates this type of disease is sensitive to the drug cisplatin.

The study, appearing online in the April 19 Journal of Clinical Investigation and in the journal's May print issue, shows that triple-negative breast cancer expresses larger amounts of two proteins, delta-Np63 and TAp73. Delta-Np63 binds to TAp73 and prevents it from killing cancerous cells. Cisplatin does the trick, though, and releases TAp73 from delta-Np63. This causes the cells to die and offers hope for a sometimes hopeless disease.

Tykerb has been approved by the FDA for use in conjunction with the chemotherapy drug Xeloda. Tykerb is a cancer medication that more precisely targets tumors without killing lots of healthy cells in the process.

Herceptin and Tykerb target a protein called HER-2/neu but work in different ways. Herceptin targets the outside of the HER2 protein and Tykerb works from the inside of the cell. This difference can give advanced breast cancer patients another drug to switch to if Herceptin stops working for them.

Glaxo said that Tykerb will be available in two weeks. The results of a study showed that Tykerb worked so well that the international study was stopped early and all the participants were offered the drug.

The FDA said it was too early to know if women taking Tykerb and Xeloda would live longer than those taking the latter drug alone.

Dr. Steven Galson, FDA drugs chief, said "Today's approval is a step forward in making new treatments available for patients who have progression of their breast cancer after treatment with some of the most effective breast cancer therapies available."

A study appearing in the Journal of Clinical Oncology reveals there may be something out there that can extend the lives of patients with recurrent prostate cancer.

This something is a new class of anti-cancer targeted drugs that scientists at Cedars-Sinai Medical Center in Los Angeles say are quite promising, despite their ineffectiveness in some prostate cancer patients with no previous chemotherapy treatment.

Pertuzumab, a molecular targeted compound that has been used successfully in ovarian cancer patients, has been shown to block the human epidermal growth factor receptor family by binding to and inhibiting the function of HER2 receptors. They essentially block a key pathway that leads to cancer growth. And this blockage can possibly offer a better, longer life for recurrent prostate cancer patients whose diseases no longer respond to traditional chemotherapy.

Pertuzumab, marketed under the brand name Omnitarg by Roche and Genentech, is just one of many targeted cancer therapies that give researchers hope that cancer may one day be a lifetime disease that can be skillfully managed.

I blogged about Diagnosis of triple-negative breast cancer back in November. This topic seemed to get many responses from women who fit into this breast cancer 'category'.

I read a report today that discussed new data that can add to the traditional pathology testing, tumor size and lymph node status to name a few, for women with triple negative disease. This would not be a new treatment for triple negative breast cancer, but I believe this information found to be very important for future discoveries that might lead to more options for triple negative breast cancer patients.

What was discussed was the assessment of basal cytokeratins and androgen receptors in patients with triple negative breast cancer. The researchers are trying to identify prognostic markers that might signal more aggressive behavior of these specific tumors.

The only thing this seems to be able to help with at the moment is getting physicians to understand if you have a triple negative breast cancer that is more aggressive, thus warranting more aggressive treatment.

For those with triple negative disease this might not seem that great, however they are studying what makes these tumors tick and I think this will eventually evolve into new targeted treatments.

If the experimental breast cancer drug Tykerb continues to prove successful in study participants, it could be headed for FDA approval.

Tykerb, now in international study, showed in early studies to be even more effective and to have fewer side effects than similar breast cancer drug Herceptin. Both drugs are part of a cluster of targeted therapies that attack cancer cells while sparing healthy cells. Designed for use on women whose breast cancer is HER2 positive -- meaning it contains too much of an aggressive protein -- Tykerb may be a wonder drug, with the capability of effectively keeping breast cancer at bay.

Dr. Paul Goss of MA General Hospital says, "We're seeing Tykerb, which is a pill, which is easier to take, has a broader attack and gets inside cells. It's like an electrical circuit that's turned on, and Tykerb can pull the lever, the circuit breaker, and switch it off."

Myocet is in its last clinical trial phase prior to FDA review. The trial is enrolling patients to evaluate the investigative chemotherapy agent Myocet (liposomal encapsulated doxorubicin) in addition to standard therapy for HER2-positive breast cancer.

Myocet is a chemotherapy agent that contains the active form of doxorubicin, you might better know it as Adriamycin. This chemotherapy drug is formulated to reduce the side effects associated with Adriamycin. Myocet allows for more of the active drug to be delivered directly to cancer cells, sparing healthy cells from being damaged.

This trial will directly compare the standard option of Herceptin and Taxol to the combination of Myocet, Herceptin and Taxol. Researchers are now enrolling patients with metastatic, HER2-positive breast cancer with a goal in mind to determine if the addition of Myocet to standard therapy can increase response to therapy or regression of cancer.

There are sometimes silver linings to the darkest of cancer clouds. I know -- because I have the dark cloud of HER2 positive breast cancer hanging over my head. HER2 positive means the tumor removed from my breast was aggressive. It aggressively over-expressed a protein that accelerates tumor growth. And it led to a poor prognosis -- that might be considered a good one too.

You see, research on the whole HER2 issue is turning up some pretty powerful potions. Like Herceptin -- the drug that miraculously cuts recurrence upwards of 50 percent for positive women like me. I was a lucky recipient of this drug. And the pharmacist who mixed the drug for all 17 of my infusions tells me it's really a good thing I have this HER2 problem -- because the drugs created to attack the problem may just cure me of my disease.

So in an odd turnabout -- from bad luck to good fortune -- I am not so sad my tumor was aggressive. It means there are bonus treatments for me. And if my cancer comes back and Herceptin no longer works, there is another drug called Tykerb. And now the Army is leading its own breast cancer vaccination study. The focus -- HER2.

Early study results from Walter Reed Army Medical Center in Washington, D.C. suggest a 50 percent reduction in disease recurrence for HER2 positive women who receive a vaccination of AE37.

AE37 targets HER2 and boosts the body's immune system so it can battle the protein before it stimulates growth. It's similar to Herceptin, but the activity of AE37 stimulates a patient's own immune system to recognize the cancer target rather than interacting with the target directly.

Should the Food and Drug Administration decide to support this study, it will proceed to Phase 3 testing, which includes a much larger pool of participants.

Catherine Jones has breast cancer. And she needs Herceptin in order to fight for her life. But Herceptin, a targeted drug used to treat HER2 positive breast cancer, is very expensive -- and for some time, Jones was not sure how she could possibly pay for this potentially life-saving therapy.

Jones, 49 and a resident of New Plymouth, New Zealand, decided to ask for help. So she set up the Herceptin for Catherine Trust to raise the $80,000 needed for the treatment. In less than four weeks, she received $64,600 in donations.

Jones is overwhelmed by the support and says she will continue to use the trust to raise funds -- not just for herself, but for other women in need.

The New Zealand government and its drug-buying agency Pharmac does not fund Herceptin. So most breast cancer patients who medically qualify for the treatment have no means of receiving it.

Jones, who is about to receive her third of 17 Herceptin doses, thinks she can help. She is surely off to a great start.
