# Chemotherapy
---
**chemotherapy**
need to be given through a [[central line]]
Most effective in treating fast growing cancers
• Multiple drug therapy is possible
usually done this way, to target different cell cycles
• Decreases cell resistance to single drug
• Impacts cell at different points of cell cycle
• Dose is determined by the body surface area
• Nadir is the point of therapy at which toxicity is at its maximum
Alkylating Agents
• For example Cyclophosphamide
• Nitrogen mustard derivatives
• Administered po or IV
• Alters cell DNA
• Cell cycle nonspecific
• Vesicant — no
• Uses: Cancer of head and neck, breast, ovary, or lung; lymphomas; leukemias; multiple myeloma
• Toxicity includes bone marrow depression, alopecia and hemorrhagic cystitis
Antimetabolites
5-FU fluorouracil (Adrucil)
• Administered IV
• Interferes with synthesis of nucleic acids
• Cell cycle specific- S-phase
• Vesicant — no
• Uses: Carcinomas of pancreas, breast, stomach, colon and basal cell
• Toxicity includes bone marrow depression, nausea, vomiting, diarrhea, stomatitis, alopecia
Miotic Inhibitors
For example Paclitaxel (Taxol)
Administered IV (24 hour infusion)
Arrest metaphase and inhibit DNA synthesis
Cell cycle specific- G2/M phase
Vesicant — no
Uses: Cancer of breast, ovarian, and non-small cell lung
Toxicity includes severe hypersensitivity reactions, bradycardia, bone marrow suppression
Anti-tumor Antibiotics
• Doxorubicin (Adriamycin)
• Administered IV
• Interfere with DNA/ RNA synthesis
• Cell cycle nonspecific
• Vesicant — yes
• Uses: acute leukemias; lymphomas; cancer of breast,
lung and ovary
• Toxicity includes cardiotoxicity, neutropenia
Anti-Estrogens [[antiestrogen]]
• Tamoxifen (Nolvadex)
• Antineoplastic
• Binds to the estrogen receptors on estrogen sensitive tumors
• Used to treat breast cancer and pt remains on it for several years after cancer treatment
• Administered po
• Cell-cycle nonspecific
• Toxicity includes increased risk of thromboembolism and endometrial cancer, hot flashes (pt goes into menopause), fluid retention
Aromatase inhibitors
• Arimidex (Anastrozole)
• Action: block estrogen production in postmenopausal women to treat breast cancer
• Route: oral
• SE: muscle weakness, fatigue, nausea, headache, hot flashes
• Increased r/o osteoporosis, use calcium + Vit D supplement
• May be used if tamoxifen did not work
## Potential Complications of Chemo
-Extravasation
-Alopecia
-Mucositis
-Bone Marrow Suppression-(BMS)
-Nutritional Considerations
anorexia
-Nausea and Vomiting
often given [[ondansetron]]
## Nursing Considerations
SAFETY in Handling Chemotherapeutics
• Extra precautions for pregnant, breast feeding, and those trying to
conceive (both biologic genders)
• Communicate reproductive status to leader to develop a safety plan
to reduce exposure
• Alternative assignment, Appropriate PPE, Collaborate with PCP & 0B
• Beware of possible surface contaminants
• Improper handling of hazardous drugs can lead to contamination on:
Computer, keyboards, phones, doorknobs, bedside tables, call light,
side rails
## Examples
Cisplatin (Platinol)
Class: Cytotoxic Platinum Compound
Indications: Anti-Cancer
Route: IV Central line
Expected Action: Disrupt cell cycle DNA cross-links
Expected Outcome: Stop cancer growth
Common Adverse Effects: Nephrotoxic, N/V, neuropathy,
bone marrow suppression, ototoxicity
Nursing Implications: hydration/diuretics, antiemetics,
monitor kidney function, nutrition, monitor blood counts
(anemia, immunosuppression, thrombocytopenia)
