Nursing Care for a person with Cancer

Cards (33)

  • Differentiate the three phases of cancer development:
    • Latent: time that elapses between the first genetic alteration and actual clinical evidence (includes both the initiation and promotion stages)
    • Initiation: mutations in cell genetic structure
    • Promotion: mutations lead to an increase in altered cells due to reversible proliferation
    • Progression: increased growth rate, invasiveness, and metastasis
  • Describe the role of the immune system in the recognition and destruction of tumor cells:
    • Cancer cells develop in our bodies but usually eliminated by our immune system
    • Cancer cells have altered cell surface antigens
  • Immunological Escape:
    • Cancer cells can and do evade the immune system
    • Cancer cells can mutate which weakens their surface antigens and make them less visible to the immune system
    • Cancer can create cytokines which confuse the immune system and interfere with its communication systems
    • Cancer cells can create proteins which turn off immune cells
    • checkpoint proteins
  • Sentinel Lymph Node:
    • First lymph node to which cancer cells are most likely to spread from primary tumor
    • Sentinel lymph node biopsy (SLNB): determines if cancer cells have spread to lymphatic system
    • Routinely used for people with breast cancer and melanoma
    • If sentinel node is negative it means that lymph nodes distal are not removed
  • Anatomical Site can determine the status of Cancer:
    • Named according to the organ where they originated (most common sites are the skin, lungs, female breasts, prostate, colon and rectum, uterus).
    • Are also based on the type of tissue affected (major categories include carcinoma, sarcoma, myeloma, leukemia, lymphoma)
  • Anatomical Sites:
    • Carcinoma: malignant cancer of epithelial origin
    • Squamous Cell: originates in squamous epithelium and occurs in many areas of the body
    • Adenocarcinoma: develops in mucous-producing (glandular) cells
    • Sarcoma: originates in the connective tissue (bones, cartilage, fibrous tissue, muscle, fat)
    • Lymphoma: cancer that originates in the lymphatic system
    • Leukemia: cancer of bone marrow origin
    • Myeloma: cancer that originates in plasma cells in the bone marrow
  • Histology Grading:
    • Grade 1: cells differ slightly from normal cells (mild dysplasia) and are well differentiated (low grade)
    • Grade 2: cells are more abnormal (moderate dysplasia) and are moderately differentiated (intermediate grade)
    • Grade 3: cells are very abnormal (severe dysplasia) and poorly differentiated (high grade)
    • Grade 4: cells are immature and primitive (anaplasia) and undifferentiated (high grade- cell origin is difficult to determine)
    • Grade 5: grade cannot be processed
  • Clinical Staging:
    • Stage 0: abnormal cells that could grow into cancer are present but have not spread to nearby tissue
    • pre cancer: carcinoma in situ
    • Stage 1: Cancer is present but has not spread
    • early stage cancer
    • Stage 2: Cancer has spread into nearby tissue
    • Stage 3: Cancer has spread further, tumor is larger
    • Stage 4: Cancer has spread to distant parts of the body
    • advanced/metastatic cancer
  • TNM Classification System:
    • T: size of the tumor and extent of tumor invasion into tissue
    • N: spread to nearby lymph nodes
    • M: spread to distant tissue/organs
  • Surgery: used for prevention, cure or control, and supportive/palliative care
  • Chemotherapy: use of chemicals as systemic therapy
    • Can control cure, or offer palliative relief
    • Primarily disrupts the cell cycle and kills rapidly dividing cells
    • cancer cells
    • bone marrow, mucous membranes, integumentary system (skin, hair, nails)
  • Radiation Therapy: energy is emitted from an external source and travels to the intended treatment field to damage the cancer cell's DNA and destroy their ability to grow and divide
    • Used for both curative and palliative treatment of cancer
    • More than half are treated with this
    • Two types: External Beam Radiation, Brachytherapy
  • External Beam Radiation:
    • A machine called a linear accelerator is used to deliver photon external beam radiation therapy
    • First session is simulation session to map out exactly where the radiation needs to be delivered
  • Brachytherapy:
    • Implantation or insertion of radioactive materials directly into the tumor or near the tumor
    • Used for treatment of cervical, breast, prostate, and head and neck cancers
    • Intracavity for cervical cancer allows for higher dose of radiation to the cervix while sparing surrounding tissue
    • Visitors need to limit visiting time and stay 6ft or more away from patient
  • Immunotherapy: boosts the immune system to help the body find and destroy cancer cells
  • Types of Immunotherapy:
    • Non-specific immunotherapies
    • cytokines: Interferon Alfa
    • Immune Checkpoint Inhibitors
    • Pembrolizumab (Keytruda)
    • T-cell Transfer Therapy
    • CAR T therapy for leukemia and lymphoma
  • Side effects of Immunotherapies
    • Tend to be mild but can be severe
    • Include flu like symptoms, rash, diarrhea, fatigue, liver toxicity
  • Targeted Therapy: drugs designed to destroy cancer cells by focusing on a specific protein or mutation in the cancer cell that is allowing it to grow and multiply
    • examples: Trastuzumab (Herceptin) - HER2 inhibitor and Imatinib (Gleevec)
    • side effects: same as immunotherapy
    • Methods of Administration: Chemotherapy
    • Intravenous: Central venous access device
    • Chemo drugs are often vesicant can cause tissue necrosis if infused into tissue surrounding a vein
    • Oral
    • Subcutaneous, intramuscular, topical
    • Regional
    • Intracavitary: into a CAVITY
    • Intrathecal: into the CEREBRAL SPINAL FLUID
