Study Notes

Cancer Treatment Modalities

Cisplatin: A chemotherapy drug used to treat various cancers by damaging DNA.
Chemotherapy Categories:
- Antimetabolites: Include fluorouracil and methotrexate for disrupting cancer cell metabolism.
- Antibiotics: Doxorubicin hydrochloride, bleomycin, dactinomycin target cancer cells directly.
- Antimitotics: Vincristine and vinblastine inhibit cell division.
- Hormones: Estrogen, progesterone, tamoxifen citrate, and paclitaxel modify hormonal pathways in cancer.
- Biological Modifiers: Epoetin alfa and filgrastim boost immune function and red blood cell production.

Common Side Effects of Cancer Treatments

Bone Marrow Suppression: Causes neutropenia and leukopenia; monitor white blood cell count and implement infection precautions.
Anemia: Hemoglobin less than 10 g/dL; manage with oxygen therapy, iron-rich foods, and blood transfusions.
Thrombocytopenia: Low platelet count; administer platelet transfusions and use bleeding precautions.
Alopecia: Loss of hair occurs two weeks after starting treatment; offers potential solutions like ice application or wig referrals.
Gastrointestinal Issues: Treat with antiemetics before therapy; encourage small, nutritious meals.

Health Promotion and Disease Prevention

Healthy Lifestyle: Focus on low-fat diet, regular exercise, maintaining a healthy weight, and limiting alcohol intake.
Avoid Risk Factors: Reduce exposure to environmental hazards, avoid recreational drugs, and practice safe sex.
Nutrition: Consume a diet rich in fruits, vegetables, and lean protein while reducing processed foods and red meat.

Chemoprevention Strategies

Utilize medications like aspirin and celecoxib for colon cancer prevention.
Vitamin D and tamoxifen may lower breast cancer risk.
Vaccinations against HPV and Hepatitis B can reduce cancer risk.

Screening Recommendations

Regular screenings for various cancers; mammograms, colonoscopies, PSA testing for prostate cancer, and Pap tests at age 21.
Low-dose helical CT scans recommended for older adults with a significant smoking history.

Risk Assessments

Age: Cancer risk increases as age progresses.
Immune Factors: Immunosuppressed individuals have a higher risk.
Genetics: Family history of breast or colon cancer can necessitate genetic testing.

General Symptoms of Cancer

Unintentional weight loss, persistent fatigue, weakness, pain which may appear late in disease progression.

Cancer Management Overview

Employ chemotherapy and other treatments to attack rapidly dividing cells in tumors; effectiveness is higher in fast-growing cancers.

Specific Medication Toxicities

Doxorubicin causes irreversible cardiomyopathy.
Methotrexate may lead to renal toxicity.
Vincristine sulfate is linked to peripheral neuropathy.

Cognitive Effects of Chemotherapy

"Chemo brain" refers to cognitive impairment during and after treatment, affecting concentration and memory.

Radiation Therapy

Utilizes gamma rays to destroy cancer cells while minimizing harm to normal cells; includes teletherapy and brachytherapy.
Teletherapy: External radiation patients receive from a machine.
Brachytherapy: Involves placing radioactive material inside or near tumors, posing radiation exposure risks to others.

Nursing Interventions for Radiation Therapy

Ensure accurate patient positioning for consistent and effective treatment delivery.
