New Technologies For The Treatment Of Breast Cancer

The primary goal of cancer treatment is to achieve better survival and improve. Radiation therapy plays an important role in breast cancer, helps to achieve both objectives treatment.Does cancer radiotherapy improves survival? Breast cancer is an evolutionary process years. In those days, a wide surgical removal of the breast and surrounding areas has been considered the standard treatment of breast cancer. In addition, local radiotherapy in those days was able to reduce the local recurrence of the disease, but shows no effect of adding survival.Improvement survival was achieved with the addition of systemic chemotherapy in breast cancer management protocol.

Oncologists were faced with an awkward question: HOW TO IMPROVE THE LOCAL CONTROL RADIATION AND STILL NO impact on breast cancer survival? The answer came in an elegant analysis of collaboration for early breast cancer trialists' Group (EBCTCG) Authority in breast cancer research worldwide. The EBCTCG conducted a meta-analysis with raw data in prospective, randomized trial to investigate the radiation after mastectomy. The main cause of death from breast cancer has not been found that heart disease which means that the radiation to be delivered to the heart inadvertently caused an increased incidence of heart disease. An important additional observation noted by the group justifies this account - the increased breast cancer deaths was not observed mainly in patients in whom radiotherapy techniques and equipment have been used without a clear distinction in the treatment volume and the risk of organs like the heart, lungs and the other breast.

breast conservation: The importance of radiotherapy

Another area of active development of breast cancer is the development of breast conservation as a standard of care in breast cancer at early stage. National Institutes of Health (NIH) Consensus Conference on the treatment of patients with breast cancer in early stage invasive, which took place in June 1990, recommended a breast conservation treatment for most women with stage I or II breast cancer.

* Local Control: Local control is an important goal of breast conservation therapy. The incidence of local recurrence is low in appropriately selected patients receive optimal treatment of breast conservation.

* The cosmetic outcome: A measure of treatment for early breast cancer is to produce the best aesthetic result consistent with the achievement of local / regional control. Optimal long-term results requires careful integration of cosmetic surgical excision and precise radiotherapy techniques.

* Radiation therapy: Radiation therapy conference that the recommendations after breast conservation surgery.

Modern radiotherapy can be associated with significant morbidity and mortality from cardiovascular disease unless the previous radiation techniques. Currently, many centers use treatment planning computed tomography (CT) and shaping of the radiation dose using 3-dimensional conformal radiotherapy and intensity modulated to avoid treating the underlying heart disease. In addition, the integration of electron beam therapy in the protocols of radiotherapy for breast cancer allow the safe delivery of higher doses of radiation to patients.

It is clear that the availability of radiation therapy is considered an appropriate prerequisite for breast conservation with adequate dose of radiation is necessary to prevent recurrence of breast withheld. The pulse is delivered either by using an electron beam therapy, radiation therapy, 3-D conformal, intensity modulated radiation therapy, interstitial brachytherapy or intraoperative radiation therapy.
