Study Notes
- Disorder of growth, differentiation, and tumour is a topic covering growth, differentiation, anaplasia, neoplasia, and tumour.
- Growth is the process of increasing tissue size through synthesis. Differentiation is the process of specialization in cell function and morphology.
- Anaplasia is a lack of differentiation, a hallmark of malignant transformation. It implies a reversion to a lower level and is characterized by pleomorphism, disproportionately large nuclei, and loss of polarity.
- Neoplasia refers to new growth and is an abnormal mass of tissue that grows excessively. It can be benign or malignant, and cancer is the common term for all malignant tumours.
- Tumours are classified based on their behaviour and the type of tissue from which they originate. Benign tumours are non-invasive and slow-growing, while malignant tumours are invasive and capable of spreading.
- Metaplasia is a reversible change in which one adult cell type is replaced by another. It may represent an adaptive response to stress and can predispose to malignant transformation.
- Dysplasia is a term for disordered growth and is commonly encountered in metaplastic epithelia. Dysplastic lesions are often pre-neoplastic and can exhibit pleomorphism, abnormal nuclei, and abnormal mitotic figures.
- Metastasis is the spread of tumour cells to distant sites and marks a tumour as malignant. It can occur via direct seeding, lymphatic spread, haematogenous spread, or implantation.
- Carcinogenesis is the process of tumour formation caused by non-lethal genetic damage to a single precursor cell. Four classes of regulatory genes are targeted in this process: growth-promoting oncogenes, growth-inhibiting tumour suppressor genes, genes that regulate apoptosis, and genes involved in DNA repair.
- In the context of this text, the true statement is that malignant tumour cells often proliferate faster than their normal counterparts.
- Cancer therapy methods include surgical removal, radiotherapy, chemotherapy, immunotherapy, and growth hormone therapy.
- Hyperplasia, hypertrophy, atrophy, metaplasia, anaplasia, and dysplasia are terms used to describe various pathological changes in tissue.
- The learning outcomes of this module aim to provide students with a foundational understanding of the principles of general pathology and their application to systematic pathology.
- Students will learn to define terms for disease description, describe the difference between aetiology and risk factors, and explain the pathogenesis and characteristics of major categories of disease.
- They will gain knowledge of specific organ disorders and their impact on body systems, understand pathology and clinical chemistry data for clinical diagnosis, and show basic knowledge of key areas of clinical medicine.
- The module will cover control of disease via medical interventions, public health, and the outcomes of various diseases.
