Objectives

By the end of this UCO, students should know the cellular and molecular characteristics that are inherent to tumor invasion and metastasis, as well as recognize that these characteristics might be modulated by the tumor microenvironment.

These concepts will be explored using specific tumor models. The acquired knowledge will serve as the basis for the UCO Alvos Terapêuticos em Oncologia, where clinic cases and therapeutic strategies will be discussed.

Learning outcomes and competences

At the end, the students should be able to:

- Define and describe the principal characteristics of the tumour cells

- Define the concept of invasion and of metastasis

- Identify cellular and molecular alterations inherent to invasion and metastasis

- Describe the concept of pre-metastatic niche and micrometastases dormancy

- Discuss the concept of cancer stem cells and their importance for tumour heterogeneity

- Outline the role of the tumour microenvironment, in particular of the immune system, for invasion and metastasis

Working method

Presencial

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

The UCO’s proposal is justified by the need of offering to students of the Integrated Master in Medicine from FMUP, basic knowledge on oncobiology, with a special focus on cellular and molecular activities inherent to tumour invasion and metastasis. The UCO promotes a strong discussion component, allowing students to reflect on the topics discussed, formulating their own personal opinion face to concepts and dogmas established in the area. It is also intended that students receive training to prepare the development of their own research projects in the oncobiology field. The programmatic content of this UCO aims to provide basic concepts relevant for the clinical practice in medical oncology.

Program

1. “Hallmarks of Cancer”: maintenance of cell proliferation; cell cycle suppressor signals evasion; resistance to cell death; replicative immortality; mutations and genomic instability; inflammation in the tumor microenvironment; immune system evasion; cell metabolism reprogramming; angiogenesis; invasion and metastasis

2. Cell and molecular alterations associated to tumor invasion: altered cell-cell and cell-extracellular matrix (ECM) adhesion, epithelial-mesenchymal transition, proteolysis and migration/motility

3. Cell and molecular alterations associated to metastasis: intravasation, extravasation, new organ colonization and metastatic specificity

4. Pre-metastatic niche and micrometastasis dormancy

5. The role of cancer stem cells and tumor heterogeneity for invasion and metastasis

6. The tumor microenvironment as regulator of cancer cell invasion and metastasis: the ECM, immune cells (macrophages, lymphocytes, dendritic cells), fibroblasts and myofibroblasts, adipocytes

Teaching methods and learning activities

The lectures are intended to provide the necessary knowledge regarding the biological processes involved in invasion and metastasis, using reference of concrete tumour models. The sequence of the subjects discussed aims the accumulation of knowledge providing students an integrative view and an informed argumentation.

The seminars, presented by researchers/professors specialized in oncobiology, will establish the connection between addressed concepts, research and clinical practice.

The presentation of scientific articles will allow students to discuss the topics addressed along the UCO and to evaluate their ability to integrate the acquired knowledge, to interpret results and to formulate their own critical opinion.

Type of evaluation:

Presentation and discussion of scientific articles previously provided and accounting for 25% of the final classification.

Written examination (2 hours): test with multiple-choice questions and open questions with short answer, accounting for 75% of the final classification.

The classification will be express in a scale from 0 to 20, according to both evaluation criteria.
