Breast Cancer Treatment Recognizesrevolutionary Techniques

WHAT ARE TARGETED THERAPIES?

Targeted therapies as the name suggests are advanced techniques of cancer treatment that specifically target precise features of cancer cells without causing any damage to the healthy cells surrounding it. A few of these targeted therapies are just antibodies similar to the natural antibodies made by our immune system; these are called immune targeted therapies. Except the cases of pregnant and nursing women, these are believed to be safe and successful.

These therapies are usually recommended for patients alongside chemotherapy. Targeted medications are developed by recognizing the precise abnormalities in the molecules that are responsible for malignant cancerous tumors. These targeted medications do not work like standard drugs used with chemotherapy and are also believed to be safer and with less adverse effects.

NEW PROSPECTS OF CANCER TREATMENT

Statistics from a path breaking study by researchers from the CHUM Research Centre (CRCHUM) and the Peter MacCallum Cancer Centre in Australia have made some new revelations about the future of breast cancer treatment. They suggest that the hyperactivity of a protein,in as many as 20 to 30 {abffe3e1318a9624791ae4064333f2f75374704dc13d09152fd440b16c9e1c0c} of breast cancer patients, the human epidermal growth factor-2 (HER2), is the main cause of the rapid growth of cancer cells.

About 25{abffe3e1318a9624791ae4064333f2f75374704dc13d09152fd440b16c9e1c0c} of more aggressive and difficult to treat breast cancers are HER2-positive. These are generally.HER2 positive breast cancers produce excess of this protein found on the surface of cancer cells. It receives signals that lead the cancer to grow and spread. HER2/neu status is determined by testing the tumor tissue of all breast cancer patients in any cancer center PA.

USE OF HERCEPTIN IN TARGETED THERAPIES

Herceptin-(chemical name: trastuzumab), – the man-made version of a specific immune system protein has been used to treat these kinds of is given intravenously to patients who have positive lymph nodes and an abnormal HER2/neu gene. It is an approved drug to treat advanced-stage HER2-positive breast cancers and reduce the risk of recurrence of early-stage HER2-positive breast cancers with a high risk of recurrence by the U.S. Food and Drug Administration. Though many researchers have suggested that Herceptin can reduce the risk of recurrence, only when the cancer is bigger than 0.5 cm and the cancer is grade 2 or 3.

In addition to blocking cancer cell proliferation this drug also provides stimulation to the production of inter ferons, which activate lymphocytes or immune cells. The new study suggests that the success rate of treatment is enhanced by the presence of lymphocytes in tumors.

WHAT TO ASK ABOUT NEW THERAPIES?

Whenever a breast cancer patient is recommended a new therapy, the following queries must be made:

These targeted therapies have also brought some other related issues in focus:

WHAT ARE THE EXPECTED SIDE EFFECTS OF NEW THERAPIES?

These new therapies have proven to be safe but there are some minor side-effects like:

Most of these cease to happen after the first session. There is also a slight possibility of temporary heart damage e which needs constant checking by the doctor and is reversible.

Lately there has been a rise in aggressive enthusiasm for these therapies which medical and research experts believe is too soon to say anything conclusively. They need to be used and analyzed for longer durations for sure results about their long term effectiveness.
