01132 - Molecular Pathology - Immunology (Integrated Course)

Learning outcomes

At the end of the course the student: - knows the mechanisms that lead genomic alterations to cause disease; the tumor phenotype, the etiopathogenesis and the natural history of neoplasms in a perspective of prevention and innovative preclinical approaches to the control of neoplastic disease. - will be able to apply the knowledge of the basic mechanisms of pathogenesis to specific pathologies.

Assessment methods

The Molecular Pathology course consists of a part of Genetic Pathology (2 credits-Prof.ssa Gri) and a part of Oncology (3 credits - Dr. Santoro).

The exam is unique and aims to evaluate the achievement of the didactic objectives and therefore the knowledge of the main notions of: genetic pathology oncology, with particular emphasis on molecular oncology.

The exam method will be communicated later and in any case before the start of the lessons. The final grade of the Integrated Course of Molecular Pathology and Immunology consists of the synthesis of the final assessments of the courses of Molecular Pathology and Immunology.

The assessments obtained in the various tests do not have validity deadlines (but it is advisable not to let more than a year pass) and are integrated to obtain the final exam grade. The vote is expressed out of thirty on the average of the marks. The exam is passed if a grade of not less than 18 is obtained in each course.
