How Do Anti-Cancer Drugs Work? And Can Nutrition Affect Their Effectiveness?
How do anti-cancer drugs work, and can nutrition affect their effectiveness? Anti-cancer drugs are a group of medications designed to inhibit the growth of, or destroy, cancer cells in the body. They are considered one of the main approaches to cancer treatment, alongside surgery, radiation therapy, and immunotherapy. Anti-cancer drugs come in several classes, each with a different mechanism of action depending on the type of cancer cell and the stage of the disease.
Drugs That Inhibit Cell Division (Cytotoxic Drugs)
- Drugs in this group, such as Cyclophosphamide, Doxorubicin, or Methotrexate, damage the DNA of cancer cells so they can no longer divide or continue growing. However, because certain normal cells in the body (such as skin, intestinal, or hair cells) also divide rapidly, side effects such as hair loss, nausea, or lowered immunity can occur.
Targeted Therapy
- This is a class of drugs developed to bind to specific proteins or molecules on the surface of cancer cells, such as Trastuzumab (Herceptin) for breast cancer with high HER2 expression. These drugs act more specifically, reducing side effects on normal cells.
Immunotherapy
- This approach stimulates the body's immune system to recognize and eliminate cancer cells, such as immune checkpoint inhibitors (e.g., Nivolumab, Pembrolizumab).
Hormonal Therapy
- Suitable for cancers that grow in response to hormones, such as breast cancer and prostate cancer, using anti-hormonal drugs to reduce or block the hormones that promote cancer cell growth, such as Tamoxifen or Anastrozole.
How Important Is Nutrition for Cancer Patients?
Proper nutrition helps support treatment so it works more effectively, especially during the period when patients are receiving anti-cancer drugs, when the body often becomes fatigued, immunity drops, and drug side effects appear.
Effects of Malnutrition on Treatment
- Reduces drug effectiveness
- Slows recovery
- Increases risk of infection
- Prevents patients from receiving the appropriate drug dose
Numerous studies confirm that patients with good nutritional status respond better to cancer treatment and recover faster.
Protein: A Key Nutrient for the Recovery System of Cancer Patients
Why Is Protein Important?
- Helps repair damaged cells, especially while the body is receiving drugs that destroy cells
- Builds muscle, preventing the muscle mass loss commonly seen in cancer patients
- Boosts immunity, helping the body cope with infections and drug side effects
Patients should receive approximately 1.2-2.0 grams of protein per 1 kilogram of body weight per day, which may be higher than for a healthy person.
Protein Shakes: A Convenient Recovery Option for Cancer Patients
Suitable for patients who have difficulty eating, such as those with loss of appetite, nausea, or reduced food intake after receiving anti-cancer drugs. Protein shakes are a drink that provides high energy and protein in a small volume, helping patients get adequate nutrition.
Benefits of Protein Shakes for Cancer Patients
- Help maintain muscle mass
- Restore energy after receiving medication
- Help the body tolerate anti-cancer drugs better
- Increase nutrient absorption, especially in patients with a weakened digestive system
How Does Good Nutrition Support the Effectiveness of Anti-Cancer Drugs?
Improves the Body's Response to Treatment
- If the body is strong from adequate protein, vitamins, and energy, it can respond better to drug treatment.
Helps Reduce Drug Side Effects
- Appropriate foods, such as brown rice, fresh vegetables and fruits, and protein from fish, eggs, or beans, can help ease fatigue, diarrhea, or nausea.
Prevents Acute Malnutrition
- Patients often experience loss of appetite or are unable to eat normally. Supplementing with easy-to-digest foods, such as clear soup, fresh fruit juice, or protein shakes, helps prevent the body from becoming malnourished while receiving treatment.
Sample Meal Plan for Cancer Patients Receiving Anti-Cancer Drugs
Breakfast
- Fish rice porridge is an easy-to-digest, low-fat source of protein. Steamed egg is also a source of protein that is gentle on the digestive system, making this a light breakfast that still provides high energy and protein.
Mid-Morning Snack
- Vanilla-flavored protein shake is a convenient way to boost energy and protein between main meals, helping keep blood sugar levels stable and reduce feelings of hunger.
Lunch
- Brown rice is a source of complex carbohydrates and fiber. Clear soup with tofu and minced pork provides easy-to-digest protein, and the broth helps things go down smoothly. Adding fruit boosts vitamins, minerals, and antioxidants.
Afternoon Snack
- Banana smoothie blended with yogurt is an easy-to-digest snack that provides energy from the banana and probiotics from the yogurt, which are good for the digestive system.
Dinner
- Steamed rice is a source of carbohydrates. Fresh shrimp Kaeng Liang is a dish with a wide variety of vegetables, rich in vitamins, minerals, and fiber. Fresh shrimp is a good source of protein that helps nourish the body.
Before Bed
- Honey-flavored protein shake mixed with almond milk is a light drink before bed. Almond milk is easy to digest and low in calories, honey provides a small amount of energy, and the protein helps with recovery and body repair during sleep.
Precautions When Choosing a Protein Shake for Cancer Patients
- Avoid high sugar content; choose a Low Sugar or sugar-free formula
- No added chemicals; make sure there are no preservatives or synthetic colors
- Choose high-quality protein, such as whey protein isolate or plant-based protein (soy, pea) that is easy to digest
- Suitable for those with intestinal or kidney issues; consult a nutritionist or doctor before use if there are underlying conditions
How Anti-Cancer Drugs and Nutrition Work Together
- Anti-cancer drugs help destroy or inhibit cancer cells
- Proper nutrition helps give the body strength to cope with side effects and recover faster
- Protein shakes help supplement nutrients, especially for those who can eat only small amounts
