Cellular Review • Evolve 3 D Cellular Differentiation on web site
Oncology • Biology of abnormal cancer cells • They have continuous or inappropriate, usually faster growth or larger growth patterns • They have no specific morphology and often do not resemble their parent cells = anaplastic • They do not respond to signals for apoptosis = programmed cell death
Oncology • Biology of abnormal cancer cells • Have a large nuclear – cytoplasmic ratio; the nucleus may occupy most of the cell area • They lose some or all of their normal cell functions • They do not make fibronectin, and thus cannot connect easily and break off easily
Oncology • Biology of abnormal cancer cells • They are able to migrate throughout the body = metastasis • They invade other tissues and types of cells. • They are not controlled by contact • They have more or less chromosomes than the parent cells = aneuploid or a mutation of the genes
Oncology • Cancer development • Initiation – there are many theories as to when the genes in the cells are damaged, maybe in utero, from physical or chemical exposure, latent oncogenes, viruses, or a lack of suppressor genes from our parents, and at this point the cell is not dividing.
Oncology • Skin cells
Oncology • Cancer development • Promotion - the stage when the abnormal cell starts to divide, may be stimulated by environmental changes, hormones, drugs, or irritants
Oncology • Cancer development • Progression – the phase when the abnormal cells have continued to grow into a Primary tumor, may produce angiogenesis factors which supply blood and vascular nourishment to the tumor. The tumor may have subcolonies of cells with different genes and features
Oncology • Cancer development • Metastasis the movement of cancer cells into other organs of the body, thus creating new tumor sites.
Oncology • Cancer grading and staging • Cancer is graded upon the resemblance to normal cells = G (The higher the number, the worse the grade of cancer) i. e. G 1, G 2, G 3, G 4 • • • Staging is based upon the presence of a primary tumor = T involvement in lymph nodes = N and appearance of metastasis = M Numbers of the stage range from x = none to 3 or 4 for each letter
Oncology • Is this a high grade or low grade cancer? • Case study Julie has a breast lump in her right breast, and has also found one in her right armpit. Biopsy and lumpectomy were performed. The tumor was graded G 3, T 2, N 2, M 1.
Is this a high grade or low grade cancer? 1. High 2. Low

Oncology • Malignant Lymphomas – 2 types • Hodgkin's Lymphoma – most common cancer in 10 to 20 year olds (young adults). Associated with an inflammatory process related to +EBV/mono infection. • Diagnosis: Classic Reed-Steinberg cell with two mirrored nuclei, CT scan • Symptoms: Extreme fatigue, enlarged lymph nodes that are painless. May progress to weight loss fevers, night sweats
Oncology • Malignant Lymphomas – 2 types • Hodgkin's Lymphoma • Treatment – combined radiation and chemotherapy, stem cell transplants if resistant type or recurring • 85% curable • (90% in some institutions)
Oncology • Malignant Lymphomas – 2 types • Non-Hodgkins Lymphoma – 3 times more common than Hodgkin’s lymphoma, can either be T-cell lymphomas, or B-cell lymphomas • Can be low grade or high grade disease. B-cell lymphomas = 50% and usually are more aggressive tumors. Since they grow faster, they are also more sensitive to radiation and chemotherapy
Oncology • Malignant Lymphomas – 2 types • Non-Hodgkins Lymphoma • Diagnosis: bone marrow biopsy, CT scan, lymphoma panel with CD markers • Symptoms- adenopathy, spleenomegaly with vague abdominal pain, back pain, and since immunity B or T-cell function is affected- the patient is more prone to infections. Subcutaneous T-cell lymphoma is a classic discoid rash on the upper body and trunk that does not respond to steroids or creams. • NHL can progress rapidly to leukemia if untreated.
Oncology • Malignant Lymphomas – 2 types • Non-Hodgkins Lymphoma • Treatments: Monoclonal antibodies, chemotherapy with Fludara/Fludarabine, radiation therapy, and bone marrow implants
Oncology • Leukemia– hematopoeitic cancer of the stem cells. These stem cells proliferate into non-functional immature white cells. • More children get leukemia than any other type of cancer and it is the #1 cause of death in children. • Anyone can get leukemia at any age.
Oncology • Leukemia -4 types • • • Acute lymphoblastic leukemia (ALL) Acute myelogenous leukemia (AML) Chronic Lymphocytic leukemia (CLL) Chronic myelogenous leukemia (CML) Anagram – ALL Ani. Mals are CLear. Ly Ca. Me. Ls
Oncology • Leukemia –ALL suspected cause is a T -cell virus (HTLV-1) – 85% is seen in children, 25% in adults 30 -to-40 y. o. • Diagnosis: peripheral blood smear after abnormally high white count, bone marrow biopsy shows lymphoblasts >50%m may have decrease in platelets. Lumbar puncture to determine CSF involvement
Oncology • Leukemia –ALL • Symptoms – fatigue, anorexia, malaise, weight loss, bleeding, infections, headaches, adenopathy, spleenomegaly, gingival hypertrophy, hepatomegaly, bone or joint pain • Treatment: complete response is a bone marrow aspirate with < 5% blasts. Chemotherapy – vincristine, prednisone, danorubicin, methotrexate, • Maintenance therapy – 6 weeks of • 6 -mercaptopurine and methotrexate low dose therapy
Oncology • Leukemia – AML – more common in patient’s with chromosomal genetic disorders, exposure to benzene or radiation. Use of alkylating agents for breast, ovarian, or myeloma are associated with a later malignancy of this type. • Symptoms- are like ALL with the additions of anemia, thrombocytopenia, visual disturbances, epistaxis (nosebleeds), headache with vomiting, dysphagia, papilladema, menorrhagia (lots more bleeding problems)
Oncology • Leukemia – AML • Diagnosis: peripheral blood smear shows Auer bodies (rods), platelets less than 20, 000/mm 3, bone marrow biopsy • Prognosis – poor prognosis if patient has already received radiation or chemotherapy, or has a WBC >100, 000
Oncology • Leukemia – AML • Treatment: Cytaribine chemotherapy in combination therapy with Danorubicin or doxirubicin, works 65% of the time. • Bone marrow transplant or stem cell transplant.
Oncology • Leukemia – CLL – staged 0 -5 • chronic diseases have more mature cells, majority of CLL is B-cell proliferation – 95%. Only 5% are Tcells, more common in people with autoimmune diseases, i. e. SJogren’s, SLE, hemolytic anemia • Symptoms: skin and respiratory infections, fatigue, thrombocytopenia, anemia, spleenomegaly
Oncology • Leukemia – CLL • Diagnosis- peripheral blood smear, bone marrow biopsy • Treatments: Gleevac – drug of choice; chemotherapy in combinations, spleenectomy, radiation therapy to spleen, bone marrow transplant, stem cell transplants
Oncology • Leukemia – CML (last is the Ca. Me. L) - More common after radiation exposure, benzene exposure, less common than the other types of leukemia, and occurs most often between 50 -60 y. o. • Diagnosis: hallmark is the presence of the Philadelphia Chromosome, Chromosome #22 is missing part of the long arm which is translocated to Chromosome #9. This is present in 95% of those patients with CML. • WBC >100, 000 with proliferation of all types of mature and immature white cells. • Bone marrow biopsy
Oncology Leukemia – CML • Symptoms: same as other leukemias with chronic fever, sternal tenderness and dyspnea – usually due to severe anemias • Treatments: chemotherapy with Bisulfan and hydroxurea, other combination chemos, • Interferon alpha 2 b to suppress the expression of the Philadelphia chromosome. • Bone marrow transplant or stem cells
Oncology • Bone marrow and stem cell implants New treatments for: Acute myelogenous leukemias (AML) Acute lymphoblastic leukemias (ALL) Myelodysplasia syndromes (MDS) Chronic myelogenous leukemias that do not respond to chemotherapy (CML) Blast crisis Pediatric acute leukemias Non-Hodgkins lymphoma Large B-Cell lymphoma Multiple myelomas
Bone marrow and stem cell implants
Oncology • Bone marrow and stem cell implants • Procedure= multiple punctures • Marrow acquisition from donor or when patient is in remission, or stem cells from umbilical blood of a matching sibling or family member • Marrow is filtered to purge tumor cells, fat and bone particles, then place in a blood bag for cryopreservation.
Oncology • Bone marrow and stem cell implants Preparing Recipient: • Marrow recipient is given high dose chemotherapy alone or in combination with radiation to suppress immune system, open spaces in the marrow, and kill remaining cancer cells. • Bone marrow is thawed and infused through a central venous catheter
Oncology • Bone marrow and stem cell implants Preparing Recipient: • Stem cells are infused after thawing • Post-procedure: • Patient is supported through the period of aplasia, 10 to 30 days, while in reverse isolation and on graft immunosuppressants, • Observed for signs of Graft-versushost disease and/or infection
Oncology • The waves of the future: • Stem Cell Research • Oncogene therapy – now that cancer cells are being genetically tagged, we can tell which growth factors are present, and which enzymes turn off the gene. Soon all gene markers will have a pill that matches the enzyme, i. e. IRESSA is a tyramine kinase inhibitor, and stops the tumors growth that use tyramine kinase
Oncology • Stem Cell Induction – there are new drugs out for stem cell induction to immunosuppress the patient, even in deadly cancers, i. e. Multiple Myeloma. Recently, the combination of lenalidomide(Revalamid), bortezomib (Velcade) and dexamethasone produced a 98% response rate in patients
Oncology • The waves of the future: • Cancer vaccines • Oncology is the science of cancer and treatment of all cancer patients. It is one of the most demanding and rewarding fields in medicine. • The future is open for a cure.
