Why ADCs Are Called ‘Smart Bombs’ in Cancer Treatments

Modern oncology has given rise to many different treatment approaches that are effective in tackling cancer with precision. But have you heard about ‘smart bombs’? Doctors use this term to describe a treatment that is designed to attack the cancerous cells directly without harming other healthy tissues. In therapies like chemotherapy and radiation, the treatment flows through the entire body and damages cancerous as well as healthy cells. But antibody-drug conjugates, or ADCs, work differently. It only attacks the cancer tumor and spares the non-cancerous cells. This results in more accuracy.

How do ADCs find and attack cancer cells?

Antibody-Drug Conjugates are designed to recognize cancer before it spreads. Each molecule of ADC has a special marker that binds to the specific protein found on cancer cells. This protein detects cancer cells and separates them from the healthy ones. Once the antibody attaches to the cancer cell, the ADC medicine is pulled inside. Only then is the chemotherapy drug released that does its work. This accuracy limits the exposure to the surrounding healthy tissue. The goal isn’t to eliminate the side effects but to focus on treatment where it’s needed most.

Controlled drug releases inside the tumor

The targeted therapy approach of ADC is what makes it different from the traditional approaches. When the chemotherapy drug travels through the bloodstream, it stays inactive and reduces exposure to healthy cells. Once the medicine is inside the cancer cells, its enzymes break the linker that holds the drug in place. This allows the drug to be released only when it’s needed. This controlled release of the drugs makes the treatment more precise and safe to adapt.

Precision without harm

Due to the targeted therapy approach of ADC, it reduces the impact of medicine on healthy cells. The following are ways in which it protects the healthy cells:

• Targeted delivery: ADCs are designed to bind specific biomarkers on cancer cells; healthy cells are less likely to absorb this medicine.
• Inactivity during circulation: The medicine remains inactive while traveling through the bloodstream and reduces the damage.
• Lower risk of collateral damage: It releases drugs inside the cancerous tumor that reduce side effects like nausea, hair loss, and fatigue.

Why ADCs are not risk-free

ADCs are designed to be smarter, but they also come with a few side effects. Even with targeted precision, healthy cells may get unintentionally affected. Understanding how patients respond to the treatment can help doctors plan a more accurate treatment plan.

Progress with precision

ADCs might not be perfect, but they are effective in destroying cancer with precision and care. With the right care and balance, patients can heal faster without worrying about the side effects.
