10 Introduction What is cancer? What causes cancer?
How do we prevent cancer? How do we treat cancer?

11 What is cancer? A foreign body? A parasite? Produced by “evil” force?
Neoplasma: “Neo”=New “Plasma”= formation; Tumor: Solid mass, tumor means a neoplasm that has formed a lump

12 History of cancer The earliest known descriptions of cancer, as well as a procedure to remove breast tumours by cauterization appear in several papyri from Ancient Egypt (1600 B.C). Hippocrates: Greek physician ( B.C) “father of medicine”. He described several kinds of cancer, referring to them by the term karkinos (carcinos), the Greek word for crab or crayfish, as well as carcinoma. Body was composed of four fluids: blood, phlegm, yellow bile and black bile. Excess of black bile  cancer. Celsus ( 25 BC - 50 AD) translated karkinos into cancer, the Latin word for crab or crayfish.

13 New Technology： Microscope
1590：Dutch（荷兰） eye glass makers, Zaccharias Janssen and son Hans Janssen：multiple lenses placed in a tube: forerunner of the compound microscope and telescope. 1665, Robert Hooke ( ), English microscopist, cork --empty small compartments. The “cell” was discovered! Latin, cellula ; i.e., small compartment 1676, Anton van Leeuwenhoek, using a simple microscope, was the first to observe microorganisms 1700, first description of the nucleus by Leeuwenhoek.

14 New Theory： Cell 1838 Matthias Schleiden (1804-1881) German botanist
Thousands of plant specimens  all the vegetables are made of cells. 1839, Theodor Schwann ( ) German zoologist and physiologist  all living beings were composed of cells.

15 施莱登 1838 Matthias Schleiden

16 Cell theory All living beings are composed of cells.
The living beings may grow and reproduce themselves because the cells may in turn multiply. The new cells are formed from other pre-existing ones.

17 Histology 组织学 1852: first textbook of Histology ：
Marie François Bichat, French pathologist ( ) A texture was a “tissue” by its macroscopic physical properties. tissu = to weave (ancient French) in 1819, A. Mayer -Histology. histos = tissue logos = study 1852: first textbook of Histology ： Rudolph von Kölliker ( ) Swiss professor of Anatomy <<Handbuch der Gewebelehre>> (i.e., The book for teaching tissues)

18 Histology of Tumor A foreign body? A parasite?
Produced by “evil” force? Tumor under microscope: Mass of cells Similarity to surrounding tissue Less organized  Tumors arise from self

19 Carcinoid Tumor of the Ileum
大肠 小肠 a slow-growing type of neuroendocrine tumor 小肠： 十二指肠(Duodenum), 空肠(Jejunum), 回肠(Ileum).

22 closely packed, uniform round cells with small, central nuclei

23 Classification of tumors
Based on clinical effect on patients Based on location/tissue of origin Based on microscopic features Stages of tumor

24 Based on clinical effect on patients
Benign: Grows locally Without invading of adjacent tissues Malignant Invade nearby tissues Spawned metastasis

25 Clinical effect of Benign tumor
Secrete high levels of hormones Grow only in one place, cannot spread or invade other parts Be dangerous if they press on vital organs

29 Pituitary tumor （Benign)
Because she is illiterate, since 1992 Yao Defen has been forced to earn a living by traveling with her father and performing.

30 Acromegaly（肢端肥大症）

31 Clinical effect of Malignant tumor
90% cancer deaths are due to metastasis Once metastatic cells are attached to the basement membrane (a physical barrier that seperates tissue components), they break through with the help of an enzyme called type IV collagenase. Cancer cells then move through the blood stream enabling them to spread to other parts of the body. A secondary tumor may form at another site in the body. This is a file from the Wikimedia Commons

更令人关注的是，2012年中国新增癌症病例高居世界第一位，肝癌和食管癌患者约占全球一半，死亡分别占全球的51%和49%；胃癌症例和死亡均占全球40%；鼻咽癌80%发生在中国。 全国肿瘤登记中心发布的《2012中国肿瘤登记年报》

36 Cancer Cell types Most adult cancers are carcinomas
Epithelial origin In contrast, most childhood cancers are: Leukemias/lymphomas Blastomas → Embryonal cells Sarcomas → Mesenchymal origin Source:

37 Based on tissue/cell of origin
Carcinomas = epithelia derived >80% of all human cancer-related deaths 1. Adenocarcinoma  gland epithelia 2. Squamous cell carcinoma  Seal, protective layers 3. Other

38 Classification of Epithelium
Simple: One cell layer Stratified: two or more cell layers Squamous: wildth>height Columnar: Height> wildth Cuboidal:wildth=height=depth

39 The Morphology of an Epithelium often Correlates with Its Function
1.Simple: One cell layer Epithelia involved in secretion or absorption Transepithelial transport 2.Stratified: two or more cell layers Transepithelial impermeability 3.Psedostratified: Maintain a stable population of cells to balance cell turnover

Lymphoma = Solid mass in lymph nodes Hodgkin’s lymphoma Non-Hodgkin’s lymphoma=lymphocytic lymphoma subtypes Leukemia=cancer cells in blood （from bone marrow)

59 2. Leukemia: cancer cells in blood
Acute lymphocytic leukemia (ALL) - 80% from B cells, 20% from T cells - Distinguished by cell surface markers Chronic lymphocytic leukemia Acute myelogenous leukemia (AML) - Small rim of cytosol, large nucleus - Pre-granulocytes (precursors of monocyte/macrophage) Chronic myelogenous leukemia - Bone marrow derived Multiple myeloma  Plasma cell derived

73 Stages of tumor Contemporary practice is to assign a number from I to IV to a cancer, with I being an isolated cancer and IV being a cancer which has spread to the limit of what the assessment measures. The stage generally takes into account the size of a tumor, whether it has invaded adjacent organs, how many regional (nearby) lymph nodes it has spread to (if any), and whether it has appeared in more distant locations (metastasized). The most clinically useful staging system is the tumor, node, and metastasis (TNM) staging system developed by the American Joint Committee on Cancer (AJCC) in collaboration with the Union for International Cancer Control (UICC), herein referred to as the AJCC TNM staging system. The AJCC TNM system classifies cancers by the size and extent of the primary tumor (T), involvement of regional lymph nodes (N), and the presence or absence of distant metastases (M).
