According to new researches for the treatment of breast cancer says that a new simple and non-invasive imaging method helps in determining appropriateness of breast cancer treatment, thereby reducing the need for invasive tissue sampling.
Jens Sorenson, one of the researchers from the Uppsala University in Sweden said that “this new method for the betterment of the treatment might substitute invasive tissue sampling in near future.”
An important tool for deciding the correct treatment for the breast cancer is by measuring the growth factor of HER2 (Human Epidermal growth factor Receptor type 2). The treatments for HER2 are quite expensive but it has been proved successful in saving the lives of many people.
The examination of tissue samples that are obtained by surgery or needle biopsies from the liver, bones and any other organs reveals the current diagnosis of elevated HER2 expression. The researchers currently studied about the treatment with the aim to develop a new, simpler and non-invasive technique that are based on the whole body PET/CT (Positron Emission Tomography/Computerized Tomography) imaging. The results of this image analysis is compared to the invasive measurements in the same patients.
This study included 16 women with the simultaneous ongoing treatment of metastatic breast cancer. When a disease originated in one part of the body gets spreads to other parts of the body is termed as metastatic cancer. The amount of HER2 expression in the metastases was accurately measured with this new method. Additionally, the amount of HER2 expressions that were now and then found in metastases was different from primary tumor. This change led to change in therapy in several patients.
As per wordings of Sorensen, their study resulted in two patients starting therapy and one patient ending therapy with HER2 targeting drugs. This study was also published in the journal Theranostics for spreading this news among people.
