  6. 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

  7. 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

  8. 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

  9. 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.

  10. Oncology • Skin cells

  11. Oncology • Cancer development • Promotion - the stage when the abnormal cell starts to divide, may be stimulated by environmental changes, hormones, drugs, or irritants

  12. 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

  13. Oncology • Cancer development • Metastasis the movement of cancer cells into other organs of the body, thus creating new tumor sites.

  14. 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. G1, G2, G3, G4 • 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

  15. 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 G3, T2, N2, M1.

  16. Is this a high grade or low grade cancer? • High • Low

  17. Oncology • Julie opted to have a lymphectomy of her right arm lymph nodes, and started radiation treatment right away. Her doctor also suggested that she start Adriamycin IV chemotherapy to get any cells that the radiation might miss.

  18. Oncology • Cancer Risks • #1 = advancing age • #2 = smoking tobacco • Hormones – Prempro caused a substantial increase in breast cancer on the HERS trial • Genetic inheritance of oncogenes and autoimmune diseases • Environmental exposure • Excessive intake of dietary fats

  19. Oncology • Cancer risks • High alcohol consumption • Low dietary vegetables and fiber (sources of antioxidants) • Previous Viral infections: Hepatitis B or C Herpes viruses Papilloma viruses (HPV) Retrovirus HTLV –I

  20. Oncology • Types of cancer cells are named for their site of origin: • Adenocarcinoma • Carcinoma in situ (CIS) • Squamous • Basal cell • Astrocytomas • Melanomas • Sarcomas • Lymphomas

  21. Oncology • Symptoms of Cancer • Cachexia – weight loss,unexplained • Anorexia • Anemia • Impaired immune response • Pain – when the cancer is large enough to compress nerves or organs • Lymphadema – when the tumor blocks lymph or circulatory flow • Motor or sensory deficits

  22. Oncology • The 60 year old client with small cell lung cancer is concerned that his grown children also might develop the disease. What is the nurses best response? • A. “This disease is a random event and there is no way to prevent it.” • B. “Because this disease is inherited as a dominant trait, your children have a 50% risk for developing it.” • C. “Cigarette smoking is the main cause of this disease, and helping your children not to smoke will decrease their risk.” • D. “ Lung cancer can be avoided by decreasing dietary intake of fats and increasing the amount of regular aerobic exercise.”

  23. Oncology • Cancer statistics • The top four cancers found in the United States are: • Lung • Breast • Prostate • Colorectal C

  24. Oncology • Cancer statistics • Prostate cancer is the most common site of cancer and the 2nd most common cause of cancer death in the United States • The first cause of death in males is Lung Cancer

  25. Oncology

  26. Oncology • Cancer statistics • Lung cancer has annual new cases (incidence) of 173,770 people per year: 93,110 males and 80,660 females • Annual mortality: 160,440 per year consisting of 92,000 malesand 68,510 females

  27. Oncology • Cancer statistics • 28% of all cancer deaths are due to lung cancer • This is the leading cause of cancer death in both men and women • There are more deaths from lung cancer than prostate, breast, and colorectal cancers combined

  28. Oncology • Cancer statistics • Risks for lung cancer: • Smoking (75-80% of cases) • Occupational exposure • Nutrition/Diet • Genetic factors

  29. Oncology • Cancer statistics • Prostate cancer is number two cause of cancer in men • Breast Cancer is number two cause of cancer in women • Most common non-malignant or non-fatal cancer is non-melanoma type skin cancers

  30. Oncology • The client says that she has heard that the origin of most cancers is “genetic”. What is the nurse’s best response? • A. “The development of most cancers is predetermined and not affected by environmental factors.” • B. “Cancers arise in cells that have been damaged,which may be in the genes”. • C. “ The majority of cancers are inherited” • D. “Cancer is more common among males than females.”

  31. Oncology • Lab tests for cancer • Ultrasounds to determine size • CT scan with contrast– the golden standard • Genetic markers – BRCA 1 and BRCA 2 • Tumor markers: CEA – general carcinogenic antigen PSA – prostate antigen CA-125 – ovarian CA-25,27 – breast HER 2 NEU – breast tissue needed

  32. Oncology • Lab tests for cancer • Liver function tests • CBC with diff • Renal function tests • PET scan – looks for metastasis using a radioactive glucose solution • PT, PTT, Fibrinogen, Fibrin levels

  33. Oncology • Lab tests for cancer • Pathology slide of tumor: (Should be kept for a period of years) • Determines type of tumor • Source of tumor • Aggression of tumor – whether fast growing, differentiated, or non-differentiated • Used to determine tumor growth factors and susceptibility to certain chemotherapies

  34. Oncology • Chemotherapy • Prevention chemotherapy – for high risk patients, precancerous lesions, or history of cancer • Antioxidants, vitamins • Aldara cream 3x weekly for precancerous skin lesions • Aspirin • Protease inhibitors

  35. Oncology • Chemotherapy- typically started after surgical dissection of tumor, unless the tumor is non-operative • Usually given by a long term venous access device, i.e. PICC line, implanted ports, or direct catheratization to the tumor. • Chemotherapy is usually potent and horribly scarring on normal veins

  36. Oncology • Chemotherapy • Biochemotherapy – used as in-patient or outpatient settings for cancer, MS, and viral treatments: Alpha interferon – (IFN)- Alpha 2a, Roferon, Intron-A- used for leukemias, AIDS, Hep-C Beta interferon – Beta 1b – used for renal carcinoma, melanoma, AIDS, MS, Hepatitis A, B

  37. Oncology • Chemotherapy/Biochemotherapy • Interleukin I (IL-1) • Interleukin 2 (IL-2), Proleukin– stimulates growth of T-cells and NK cytotoxic cells • – used investigationally for melanoma in Stage II to Stage IV cases on a monthly basis with a 80% non-recurrence rate

  38. Oncology • Chemotherapy/Biochemotherapy • Tumor necrosis factor (TNF) – selectively targets abnormal cells, in nature is produced by NK cells

  39. Oncology • Chemotherapy/Biochemotherapy • Vaccines HPV vaccine for cervical cancer Melanoma vaccine - for stage II only at this time, or malignant melanoma

  40. Oncology • Chemotherapy/Biochemotherapy Monoclonal antibodies – used for treatment of cancer, rheumatoid arthritis, transplants, and other autoimmune diseases.
