391 results about "Primary tumor" patented technology

A primary tumor is a tumor growing at the anatomical site where tumor progression began and proceeded to yield a cancerous mass. Most cancers develop at their primary site but then go on to metastasize or spread to other parts of the body. These further tumors are secondary tumors.

Primary tumor cell culture medium, culture method and application

The invention belongs to the technical field of medicine, and specifically relates to a primary tumor cell culture medium, culture method and application. The primary tumor cell culture method provided by the invention comprises the steps as follows: preparing a primary cell culture medium which comprises the following components: hydrocortisone, EGF, Insulin, a ROCK inhibitor, but not contains cholera toxin, and is an improvement of the existing primary cell culture medium; culturing tumor tissue epithelial cells on laid-out trophoblast cells by using the primary cell culture medium, and enabling the tumor tissue epithelial cells to proliferate rapidly under the combined action of growth factors secreted by the trophoblast cells and nutrient factors contained in the culture medium; and digesting and sub-culturing the tumor tissue epithelial cells when the tumor tissue epithelial cells grow to a cell density of about 80% to 90%. A convenient primary cell culture method is used to obtain immortalized cells possessing the biological characteristics of a patient's own tumor, and the problem of immortalization of the primary culture of tumor cells is solved, thereby realizing personalized treatment for the patient.

Method for the Diagnosis, Prognosis and Treatment of Breast Cancer Metastasis

ActiveUS20140057796A1Positive diagnosisGreat tendency to develop metastasisSugar derivativesMicrobiological testing/measurementBreast cancer metastasisPrimary tumor
The present invention relates to a method for the diagnosis or the prognosis of metastasis in breast cancer which comprises determining if the c-MAF gene is amplified in a primary tumor sample. Likewise, the invention also relates to a method for the diagnosis or the prognosis of metastasis in ER− breast cancer, as well as to a method for determining the tendency to develop bone metastasis with respect to metastasis in other organs, which comprise determining the c-MAF gene expression level. Finally, the invention relates to the use of a c-MAF inhibitor as therapeutic target for treating the ER− breast cancer metastasis.
