Molecular Biology for Pathology Technicians

Molecular biology is a discipline that has been rapidly developing and implementing in Pathology services in recent years. In the era of Precision Oncology, the study of genetic biomarkers acquires a great impact on the clinical management of patients from a diagnostic, prognostic and therapeutic point of view. At present, it is of great importance, above all due to the increasing incorporation of oncological treatments directed against specific molecular targets, which has led to the implementation of these analyzes in the therapeutic guidelines of some of the most prevalent tumors, such as lung cancer or cancer. colorectal cancer. Furthermore, the molecular detection of human papillomavirus (HPV) currently represents a new approach for the screening and prevention of cervical cancer.


This course covers the main aspects to be known by the Pathological Anatomy technician for the understanding and updating of: the characteristics and properties of nucleic acids (DNA - and circulating free DNA or liquid biopsy - and RNA) , the optimization of its obtaining from the different types of samples common in Pathological Anatomy laboratories, the different types of genetic alterations, the most used techniques for their study in the Molecular Biology laboratory and the application of these for detection of biomarkers. Thus, this course addresses, in a global and updated way, the theoretical and applied aspects that the Pathological Anatomy technician requires to develop their work in the Molecular Biology laboratory.
