Objectives

It is intended to teach knowledge of oncobiology, microbial oncogenesis (particularly oncovirology), imunophysiology of cancer as well as prevention and treatment of cancer.

Learning outcomes and competences

Students should understand the biological and molecular basis of cancer as well as the mechanisms of oncogenesis mediated by Helicobacter pylori and by oncogenic viruses. Finally, the biological basis of novel therapeutic molecular targets and resistance to anticancer drugs will be transmitted.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Students should have basic knowledge of Biochemistry, Cellular Biology, Immunology and General Microbiology (including basic knowledge of Virology).

- HTLV-1 and adult T-cell leukemia. Mechanisms of oncogenesis. Possible therapeutic targets.

 

III. Immunophysiology of Cancer

- Host defence against the tumor.

- Mechanisms of immune response in cancer.

- Escape of the cancer cells from the immunological response.

- Inflammation in the oncologic process.

 

IV. Prevention and treatment of Cancer

- Prevention.

- Novel molecular therapies.

- Cancer drug resistance.

- Progresses in the validation of molecular targets for therapeutic intervention.

- Tests of anti-tumor activity of novel molecules.

- Search of novel therapeutic approaches.

- Search of novel tumor biomarkers.

 

Theoretical-practical classes:

Discussion of subjects taught in the theoretical classes.

Resolution of problems, through the elaboration of possible experimental designs.

Discussion of scientific papers.

Elaboration and presentation of two exercises made in group (in the form of oral presentation and of poster presentation), requested by the lecturer. The distributed evaluation component of this subject will consist of these exercises/works.

One of the classes may be destined to the presentation of those exercises/works developed by the students in a conference to be organized by the lecturer, at FFUP.

Teaching methods and learning activities

- Theoretical classes (2 hours/week): presentation of the program contents, with the help of “Power Point”

- Theoretical-practical classes (2 hours/week): the theoretical-practical classes will consist essentially in the discussion and development of the concepts and topics taught in the theoretical classes. The students are invited to actively participate in these classes, in group work, through the elaboration and presentation (oral or poster presentation) of themes that will be given by the lecturer.

- The lecturer responsible for the subject will be available for pedagogical assistance to the students during the hours announced at the beginning of the semester. The students may also contact the lecturer by e-mail.

Eligibility for exams

- The presence of the students in the theoretical classes is not compulsory.

- The presence of the students in the theoretical-practical classes is compulsory, according to the “Evaluation Rules” of FFUP, except for the students who, by law, do not need to attend such classes.

-The evaluation methods of the curricular unit follow those of the “Evaluation Rules” of FFUP. The evaluation consists in a distributed evaluation with a final written exam, covering all the subjects taught.

Calculation formula of final grade

- Distributed componente of evaluation:

 The distributed evaluation will take place during the theorical-practical classes and will take into consideration the following components:

a) Elaboration, presentation as a poster and discussion of a theme given by the lecturer (from 0 to 8.0 points);

b) Elaboration, oral presentation and discussion of a second theme given by the lecturer (from 0 to 12.0 points).

The final classification of the distributed evaluation will be given at the end of the semester, in a scale from 0 to 20 points.

Both components of the distributed evaluation are compulsory.

 

- Final Exam:

The final exam will consist in a written exam, which will comprise the topics taught in the theoretical classes.

The classification of the final exam will be expressed in a scale from 0 to 20 points.

The exam is obligatory and the students will require a minimum classification in this final exam equal or superior to 9.5 points in 20.

There will be no oral exams.

 - In order to get approved in this curricular unit, the students need to obtain a minimum final classification of 10 points (see calculation of the final classification, resulting from the two components of the evaluation), according to the “Rules of Evaluation“ from FFUP. Only this final classification will be rounded up to units.

 Calculation of Final Classification:

The final classification of the curricular unit will correspond to the classification obtained in the final written Exam (contribution of 65%) plus the classification obtained in the distributed evaluation (contribution of 35%). The final classification will be expressed in a numerical scale from 0 to 20.

Examinations or Special Assignments

According to the evaluation rules of FFUP.

In case the students do not carry out one of the components of the distributed evaluation, including the cases in which the students, by law, do not need to attend the classes: the students will need to present a written monograph on the theme(s) of the evaluation component(s) they did not perform. Such monographs must be handed personally to the teacher, up to the end of the theoretical-practical classes. The classification of those monographs will correspond to the classification of the evaluation components that the students did not attend (see distributed component of evaluation).

Special assessment (TE, DA, ...)

According to the evaluation rules of FFUP.

Classification improvement

According to the evaluation rules of FFUP.

Only the evaluation component corresponding to the Final Exam can be repeated in order to improve the classification.
