Slide 1

Standards of Cancer Biology and Therapy David Dingli, MD, PhD Hematology and Molecular Medicine Mayo Clinic Rochester

Slide 2

Cancer and Age Breast Colon Testicular CNS ALL NCCC 1988 - 2004

Slide 3

Nomenclature Benign " Polyp " Malignant Epithelial "Carcinoma" Mesenchyme "Sarcoma" Hematopoietic Leukemia, lymphoma, myeloma

Slide 6

Etiology Nature Inherited disease disorders p53, BRCA1 and 2, MMR Immune lack disorders Inherited/Congenital or gained Nurture Radiation (inestimable, aftermath, radon) Chemotherapy (MDS) Viruses and microscopic organisms EBV, HTLV-I/II, H. pylori Repeated damage (Acid reflux, hepatitis)

Slide 7

Cancer pathogenesis Oncogenes myc , ras , src, abl, bcl2 Tumor silencer qualities p53, Rb , APC, MEN1, NF1 MicroRNA Transcriptome control

Slide 8

The way to disease Clonal multiplication Starts from a solitary cell Expansion in steps Pre-dangerous states Polyp, MDS, MGUS Serial collection of transformations Clonal development Resistance

Slide 9

"Signs of malignancy" Self-adequacy in development signals Insensitivity to against development signals Evading apoptosis Limitless conceptive potential Sustained angiogenesis Tissue intrusion and metastases Genomic precariousness Hanahan & Weinberg, 2000

Slide 10

"I generally believed that record would remain until it was broken." Yogi Berra

Slide 11

Tissue and tumor engineering Dingli & Pacheco, 2008

Slide 12

Cancer foundational microorganisms Present in most (all) tumors Small portion of populace No widespread marker Often impervious to treatment May be vital focus of treatment Cancer starting cells in mice

Slide 13

Genomic insecurity Is it fundamental? Typical versus irregular transformation rate 2 current perspectives Chromosomal flimsiness Gross translocations, misfortune and pick up of chromosome parts Mutator phenotype Repair qualities Xeroderma pigmentosum MMR and so on

Slide 14

Translocations Balanced Reciprocal Aneuploidy Pseudodiploid Hyperdiploid Complex Random misfortune or increase Cytogenetic variations from the norm

Slide 15

Limitless regenerative potential Hayflick speculation Limited number of doublings Telomere support Telomerase Not all tumor cells have this potential Tumor undeveloped cells

Slide 16

Self-adequacy in development signals Autocrine circles Over-articulation of Receptor is dependably "on" Downstream flags Scaltriti et al, 2006

Slide 17

Insensitivity to antigrowth signals Hanahan & Weinberg, 2000

Slide 18

Evading apoptosis External triggers Intracellular triggers Death receptors Caspases Sensors (8, 9) Executioners (3)

Slide 19

Sustained angiogenesis VEGF FGF1/2 Thrombospondin Thalidomide Avastin

Slide 20

Tissue intrusion and metastases

Slide 21

Tumor load - Staging Tumor Size, container attack Nodes Involved, what number of? Metastases Present/truant "Obscure essential"

Slide 22

Imaging CT filter PET/CT SPECT/CT MRI Staging Response

Slide 23

Prognostic scoring frameworks Host versus Disease load Disease science Co-bleak conditions Performance status

Slide 24

Therapy Surgery Radiation Chemotherapy Antibodies Small atoms Adjunctive

Slide 25

Surgery Diagnosis Therapy Curative Palliative Debulking Symptoms control Prevent complexities

Slide 26

Radiation External bar radiation Gamma photons Neutron shafts Radioimmunoconjugates Antibody focused on radiation Radioconjugates Isotope labeled to bone looking for material Free isotopes 131 I, Gallium

Slide 27

Radiation targets DNA Water Free radical era Oxygen is required Anti-oxidants are not useful Direct and circuitous impacts Not all phones are made equivalent Geometry vital

Slide 28

Radiation Consolidation "Mantle radiation" "Axillary radiation" Palliation Spinal line pressure Pain help

Slide 29

Radio(immuno)conjugates  or -emitters

Slide 30

Free isotopes

Slide 31

Chemotherapy Antimetabolites Antifolates, Purine nucleosides, nucleoside blend inhibitors Alkylators Direct DNA harm (Many), platinum Spindle harms Vinca alkaloids, taxanes Topoisomerase inhibitors Anthracyclines, Etoposide

Slide 32

Chemotherapy Often utilized as a part of mixes "Hack", "ABVD", "Air conditioning", "Taxol/Carbo" Minimizes resistance Reduces harmfulness Different reactions Can be healing in particular cases AML, ALL, HD, NHL, Testicular growth

Slide 33

Antibodies Target particular antigen Specificity is relative Various instruments of activity Complement actuation ADCC Calcium passage May synergize with chemotherapy R-CHOP and CHOP Expected or startling toxicities

Slide 34

Antibodies

Slide 35

Small particles Target oncogene item Bcr-Abl, PML-RARA , Inhibit motioning at key strides Safer than chemotherapy Specific reactions Specificity is frequently relative

Slide 36

Small atoms

Slide 38

Adjuncts Glucocorticosteroids Estrogens/against androgens/SERMs Bisphosphonates

Slide 39

The objective Tumor cells don\'t live in detachment Stroma Adhesion resistance Blood vessels Angiogenesis inhibitors Antibodies (Avastin) Small atoms (Thalidomide, different IMiDs) Immune framework Transplantation Vaccines
