Study Notes
Chemotherapy and Biotherapy Overview
- Knowledge about chemotherapy and biotherapy enhances patient comfort, satisfaction, and coping abilities.
- Anticipating adverse effects reduces distress for patients during treatment.
- Registered nurses play a vital role in educating patients and caregivers about chemotherapy and biotherapy.
Cancer Definition and Characteristics
- Cancer encompasses over 100 diseases characterized by uncontrolled cell growth and potential spread to other body parts.
- Tumors can be malignant (cancerous) or benign (non-cancerous), with malignant tumors invading nearby tissues and capable of metastasis.
- Cancerous cells can arise almost anywhere in the body, and leukemias are examples of cancers that do not form solid tumors.
Differences Between Cancer Cells and Normal Cells
- Cancer cells grow without regulatory signals, while normal cells need such signals for growth.
- They ignore stop signals and undergo uncontrolled division, spreading to nearby areas and distant sites.
- Cancer cells manipulate blood vessel growth to receive nutrients and evade the immune system by hiding or tricking immune responses.
- Genetic changes, including chromosome duplications and deletions, often characterize cancer cells.
Cancer Development and Genetic Changes
- Cancer results from genetic mutations that disrupt normal cell functions, particularly cell growth and division.
- Mutations can arise due to errors during cell division, environmental factors, or inherited genetic predispositions.
- Aging increases the risk of cancer as the body’s ability to eliminate damaged cells declines.
Types of Genes Involved in Cancer
- Proto-oncogenes promote normal cell growth; mutations can convert them into oncogenes, leading to uncontrolled cell survival.
- Tumor suppressor genes normally inhibit cell division; their alterations can result in unchecked cell proliferation.
- DNA repair genes fix damaged DNA; mutations often lead to additional mutations, contributing to cancer development.
Metastasis of Cancer
- Metastatic cancer refers to cancer that has spread from its original site to other body parts while retaining the name and characteristics of the primary cancer.
- Treatment for metastatic cancer aims either to prolong life or relieve symptoms, as it can severely affect body function.
Cancer Treatment Options
- Local treatments target the cancerous area:
- Radiation: High-dose radiation kills cancer cells and shrinks tumors.
- Surgery: Surgical removal of cancer from the body.
- Photodynamic Therapy: Uses activated drugs via light to destroy abnormal cells.
- Hyperthermia: Heats body tissue to damage cancer cells with minimal impact on normal tissue.
- Stem Cell Transplant: Restores stem cells after they are destroyed by chemotherapy or radiation.
- Chemotherapy and biotherapy are systemic treatments that affect the entire body.
Goals of Chemotherapy and Biotherapy
- Treatment aims depend on the type, location of cancer, and the patient's overall health.
- Primary goals include:
- Curing cancer when possible.
- Preventing cancer spread to other body parts.
- Slowing cancer growth.
- Eliminating cancer cells in metastasized areas.
- Providing palliative care to alleviate symptoms and enhance comfort.
Timing of Chemotherapy and Biotherapy
- Treatment may involve multiple approaches, including surgery and radiation.
- Key chemotherapy terminology:
- Adjuvant Therapy: Administered post-surgery to reduce recurrence risk.
- Neo-adjuvant Therapy: Given pre-surgery to shrink tumors, facilitating more complete surgical removal.
- Concurrent Therapy: Involves simultaneous application of therapies like chemotherapy and radiation.
Differences Between Chemotherapy and Biotherapy
- Both therapies are aimed at eradicating cancer cells but differ in methods and side effects:
- Chemotherapy: Utilizes chemical agents to treat cancer.
- Biotherapy: Employs living organisms, derived substances, or lab-created equivalents to combat cancer.
- Side effects vary significantly between the two treatments, impacting patient experience.
