Study Notes
Chemotherapy Overview
- Chemotherapy refers to a diverse range of drugs aimed at treating cancer by targeting rapidly dividing cells.
- Cancer cells continue to divide uncontrollably, making them vulnerable to cytotoxic agents commonly used in chemotherapy.
- Chemotherapy drugs can be natural compounds derived from plants or synthetically created.
Impact on Normal vs. Cancer Cells
- Normal cells typically stop dividing under unfavorable conditions and possess better DNA repair mechanisms compared to cancer cells.
- Chemotherapy also affects rapidly dividing normal cells, leading to side effects like hair loss, anemia, immune suppression, and gastrointestinal issues.
Administration of Chemotherapy
- Chemotherapy is considered systemic therapy, distributing throughout the body to target cancer cells.
- Various administration methods include:
- Oral: pills, capsules, or liquids
- Intravenous (IV): directly into a vein
- Injection: intramuscular or subcutaneous
- Intrathecal: into the space around the brain and spinal cord
- Intraperitoneal (IP): into the abdominal cavity
- Intra-arterial (IA): into the artery supplying the cancer
- Topical: applied as a cream to the skin
Biotherapy Overview
- Biological or biotherapy focuses on enhancing the body's immune system to combat infections and diseases, including cancers.
- Also known as immunotherapy, it employs biological response modifiers (BRMs) for treatment.
Mechanism of Biological Therapy
- This therapy utilizes the immune system's components to fight diseases and mitigate treatment side effects.
- Scientists can produce BRMs in larger quantities for effective therapy against various conditions, such as cancer and inflammatory diseases.
Administration of Biotherapy
- Different forms of biotherapy can be administered via:
- Intravenous (IV)
- Oral (pills or capsules)
- Topical (skin creams)
- Intravesical (directly into the bladder)
Implanted Port
- Many patients receive chemotherapy or biotherapy through an implanted port, which facilitates easier IV access.
- An implanted port reduces discomfort associated with using smaller veins.
- The port is surgically placed under the skin and linked to a vein near the heart.
Care Instructions for Implanted Port
- Avoid getting the incisions wet for 24 hours post-placement and refrain from submerging in water for 7-10 days.
- Manage soreness with prescribed pain medications.
- Contact healthcare providers if experiencing fever, incision complications, or unmanageable pain.
Maintenance of the Port
- Ensure the port is accessed and flushed every 4-6 weeks if not in use.
- Use numbing cream before accessing the port to alleviate discomfort.
- Follow specific care guidelines based on whether the port is accessed or not.
