Study Notes
Neoplastic Cell Growth
- Key characteristic: Uncontrolled cell proliferation.
- Differentiates from normal cell differentiation, which is regulated.
Abnormal Tissue Growth
- Abnormal tissue growth forming a tumor is termed neoplasia.
- Related concepts: Hyperplasia (increased cell number) and metaplasia (change from one cell type to another).
Tumor Nomenclature
- Benign tumors named using the suffix "-oma" based on their tissue of origin.
- Malignant tumors of epithelial origin use the suffix "-carcinoma".
Malignant vs. Benign Tumors
- Malignant tumors are characterized by invasiveness, poor differentiation, and potential to metastasize.
- Benign tumors are non-invasive and typically well-differentiated.
Carcinoma in Situ (CIS)
- Indicates a preinvasive tumor confined to the epithelium without invading surrounding tissues.
Anchorage-Independence
- Refers to cancer cells' ability to grow without being attached to a substrate, a hallmark of malignancy.
Telomerase and Cancer Cell Immortality
- Telomerase maintains telomere length, allowing continued cell division and contributing to cancer cell immortality.
Genetic Alterations in Cancer
- Gene amplification involves duplication of gene segments, while point mutations alter protein function.
- Tumor suppressor genes regulate cell proliferation and can become dysfunctional when mutated.
Chronic Inflammation
- Chronic inflammation promotes cancer development by increasing cell proliferation and stimulating a wound-healing response.
Cancer Staging and Diagnosis
- The TNM system describes the extent of tumor spread: Tumor size, lymph Node involvement, and Metastasis.
- Tumor markers, such as PSA for prostate cancer and AFP for liver cancer, aid in diagnosis and monitoring.
Treatment Modalities
- Chemotherapy aims to eradicate tumor cells, allowing the immune system to eliminate remaining cells.
- Immunotherapy stimulates the immune system to attack cancer cells, while targeted therapy focuses on specific molecules involved in cancer growth.
Apoptosis and Cancer Cell Survival
- Cancer's ability to evade apoptosis permits survival and accumulation of mutations, thereby contributing to disease progression.
Angiogenesis in Cancer
- Vascular endothelial growth factor (VEGF) promotes the formation of new blood vessels to supply nutrients and oxygen to tumors.
Genetic Risk Factors
- BRCA mutations significantly increase the risk of breast and ovarian cancers.
- Environmental factors like tobacco smoke and alcohol raise cancer risk by causing DNA damage.
Tumor Characteristics
- Pleomorphic cancer cells exhibit varying shapes and sizes, indicating poor differentiation.
- Anaplastic cells are poorly differentiated and lack organization, often leading to aggressive behavior.
Cancer Treatment and Management
- Combination chemotherapy enhances effectiveness by targeting various tumor growth mechanisms.
- Neoadjuvant chemotherapy shrinks tumors before surgery, while adjuvant chemotherapy aims to eliminate remaining cancer post-surgery.
Paraneoplastic Syndromes
- Symptoms can arise from tumor-induced immune responses unrelated to direct tumor effects, such as fatigue and weight loss.
Extra Cellular Matrix Degradation
- The degradation of the extracellular matrix enables cancer cell invasion into surrounding tissues, contributing to metastasis.
Neoplastic Cell Growth
- Key characteristic: Uncontrolled cell proliferation.
- Differentiates from normal cell differentiation, which is regulated.
