24
Progression in Invasion and Metastasis Appearance of Primary Tumor (Neoplasia in situ) Vascularization (Angiogenesis) Invasion Into surrounding tissue Into vascular and lymphatic systems Release of Tumor Emboli (Shedding) Systemic Transport Hematogenous Lymphatic Arrest at Distant Site Secondary Invasion: Extravasation Secondary Angiogenesis Secondary Invasion Tertiary Spread
25
Release of Tumor Emboli and Tumor Cell Shedding Invasion through thin anaplastic venous walls in tumor Facilitated by: Local trauma Diagnostic procedures Surgery Manipulation Emboli (small clumps of cells) Favored for survival by protection of inner cells Surrounded by fibrin clot May protect embolus while in circulation May facilitate survival of tumor cells at secondary tumor arrest site
26
Routes of Systemic Spread of Tumor Emboli and Tumor Cells Direct Extension Across Organ and Body Cavities Peritoneal Cavity Pleural Linings Peri-cardial Space Cerebrospinal Cavity Lymphatic Spread: Lymphatic capillaries to regional lymph nodes Hematogenous Spread: Entry via Lymphatic drainage into circulation Abnormal blood vessels in tumors Tumor cell deformability and motility
27
Arrest and Extravasation
28
Arrest of Tumor Emboli and Tumor Cells at Distant Sites Predilection for Specific Organ Sites Depends only partly on anatomical and circulatory relationships Specific Organ Homing Based on Cell Adhesion Recognition Cell-Cell and Cell-Connective Tissue Adherence Plasma membrane ligands on metastatic tumor cells Cell adhesion receptors on endothelial lining of capillaries in target organs Binding to laminin and fibronectin in extra-cellular connective tissue matrix

Turning Point Questions Coming Up Please get stuff off of the desks.
44
Primary localized carcinoma cells can become invasive and metastatic by invoking genes, gene products, and functions of mesenchymal connective tissue type cells (the epithelial-mesenchymal-transition). Name any one feature, molecule, function, or property of mesenchymal cells that could help to promote invasion and metastasis. RankResponses 1 2 3 4 5 6Other
45
The blue line and the red line in the medulloblastoma cancer (panel III) run very close together after 90 months. What does that tell you about the primary medulloblastoma with no metastasis signature?

Secondary Metastatic Growth Growth at site of secondary arrest Protection by fibrin clot? Secondary Invasion Out of vasculature into target tissue Active Passive Growth of Metastatic Nodules Angiogenesis Invasion into metastatic organ site Potential for Tertiary Invasion
48
Factors Contributing to Metastatic Spread Metastasis-Associated Up-regulated Genes: Promotion of Epitelial-Mesenchymal Transition Host Responses (not necessarily immunological) Inflammatory responses: See Macrophages and Promotion of Metastasis, Figures 14.22 and 14.23, pp. 612-613 At Primary Site At Potential Seeding Site. See Scientific American, March 2007 Article: “Deadly Dialogue”. (Not required reading but of value now or later) Clot Formation Cytokine and Growth Factor Production Tumor Responses Tumor-induced immune suppression Possible Facilitation of Metastasis by Treatment Diagnostic and surgical manipulation X-ray Damage Immune suppression by Drug Treatment by Surgery and Anesthesia by Stress Hormones

Factors Hindering Metastatic Spread Metastasis-Suppressor Genes: See Table 14.4, p. 643 e.g. TIMP: Tissue Inhibitor of Metalloproteinases or RhoGD1-2: Down-regulates Rho – Stimulator of Actin Polymerization Host Responses Activated Macrophages Natural Killer Cells Cytotoxic Lymphocytes Hydrodynamic Effects in Host circulation Failure to Recognize and Arrest at Secondary Site
