Control of these drugs, due to their peculiarities and the type of technology used in their manufacture. Manufacturing process of biotechnological drugs. For the production of biotechnological drugs, the starting point is a homogeneous material made up of microorganisms (viruses, bacteria or yeasts) or an animal cell line (such as mouse myeloma or chinese hamster ovary cells) genetically modified to obtain the biotherapeutic protein of interest. . Large-scale cultures of these microorganisms or cell lines are then obtained. The recombinant protein is isolated and purified, inactivation or elimination of possible contaminating viruses, and it is packaged in a sterile way to obtain the final product in the form of a whatsapp number list solution or lyophilized. Thus, the biotechnological drug production process basically follows four well-differentiated stages: 1) production of the original cell line that contains the gene that allows the desired protein to be manufactured. 2) culture of large numbers of cells that produce the protein. 3) isolation and purification of the protein. 4) preparation of biological treatment for use in patients. Biotechnology as a therapeutic strategy in cancer as a result of numerous research studies, it has been proven that the production of biotechnological drugs offers a wider range of possibilities to treat cancer . In this sense, one of the greatest advances in cancer treatment lies in the possibility of establishing therapeutic decisions based on the genomic and molecular characteristics of the tumor that each patient suffers from. Pharmacogenomics is based on this . On the other hand, unlike chemotherapy, which is not capable of differentiating between
