When it comes to cancer treatment, the question that often arises is — which is better, chemotherapy or targeted therapy? Both approaches aim to destroy cancer cells and prevent the disease from spreading, but they differ in how they work and how they affect the body. Choosing the right treatment depends on several factors, such as cancer type, stage, and patient health.
At Sarvesh Health City, recognized as the Best Medical Oncology Hospital in Hisar, oncologists combine advanced diagnostic tools with personalized treatment plans to determine the most effective therapy for each patient.
Let’s explore the differences between chemotherapy and targeted therapy, their benefits, side effects, and how oncologists decide which option is right for you.
Understanding Chemotherapy
Chemotherapy is one of the oldest and most widely used cancer treatments. It involves the use of powerful drugs to kill rapidly dividing cancer cells. However, since these drugs circulate throughout the body, they can also affect healthy cells that divide quickly — such as those in the hair follicles, digestive tract, and bone marrow.
How Chemotherapy Works
Chemotherapy drugs target fast-growing cells by:
-
Interrupting cell division – preventing cancer cells from multiplying.
-
Damaging DNA – making it impossible for cancer cells to repair themselves.
-
Triggering cell death – causing cancer cells to self-destruct.
Common Types of Chemotherapy
-
Alkylating agents (e.g., cyclophosphamide)
-
Antimetabolites (e.g., 5-fluorouracil)
-
Plant alkaloids (e.g., paclitaxel)
-
Antitumor antibiotics (e.g., doxorubicin)
Benefits of Chemotherapy
-
Effective for many types of cancer and stages.
-
Can be used before surgery (neoadjuvant) to shrink tumors or after surgery (adjuvant) to prevent recurrence.
-
Works well in combination with other treatments like radiation or targeted therapy.
Limitations of Chemotherapy
-
Affects healthy cells, leading to side effects such as fatigue, hair loss, nausea, and low immunity.
-
Some cancers may become resistant to chemotherapy over time.
Understanding Targeted Therapy
Targeted therapy is a more recent and advanced approach that focuses on the specific genes, proteins, or tissue environments that help cancer cells grow and survive. Unlike chemotherapy, which affects both healthy and cancerous cells, targeted therapy zeroes in on the cancer’s unique molecular characteristics.
How Targeted Therapy Works
Targeted therapy drugs are designed to:
-
Block signals that tell cancer cells to grow.
-
Stop blood vessel formation that feeds tumors.
-
Trigger immune responses to attack cancer cells.
-
Deliver toxic substances directly into cancer cells.
Types of Targeted Therapy
-
Monoclonal antibodies – lab-made proteins that attach to specific targets on cancer cells.
-
Small-molecule inhibitors – drugs that block the enzymes or proteins cancer cells rely on.
Examples
-
Trastuzumab (Herceptin) for HER2-positive breast cancer.
-
Imatinib (Gleevec) for chronic myeloid leukemia (CML).
-
Erlotinib (Tarceva) for certain lung cancers.
Benefits of Targeted Therapy
-
Precision-based treatment – attacks only cancerous cells.
-
Fewer side effects compared to chemotherapy.
-
Can be used alongside chemotherapy or immunotherapy for better results.
Limitations of Targeted Therapy
-
Only works if cancer has a specific molecular target.
-
Cancer cells can mutate, making drugs less effective over time.
-
Often more expensive than chemotherapy.
Chemotherapy vs. Targeted Therapy: Key Differences
| Aspect | Chemotherapy | Targeted Therapy |
|---|---|---|
| Mechanism | Kills all rapidly dividing cells | Targets specific molecules or genes in cancer cells |
| Selectivity | Non-specific | Highly specific |
| Side Effects | More severe (nausea, hair loss, fatigue) | Milder (rash, diarrhea, liver issues) |
| Effectiveness | Works on many cancers | Works only for cancers with specific targets |
| Resistance | Can develop over time | Can develop due to gene mutations |
| Cost | Generally less expensive | More costly but advanced |
| Treatment Goal | Control or eliminate cancer cells | Block cancer growth at molecular level |
Which Treatment Is Better?
There is no one-size-fits-all answer to this question. Both chemotherapy and targeted therapy have their advantages depending on the type of cancer and patient profile.
When Chemotherapy Is Preferred
-
When cancer is widespread or fast-growing.
-
When molecular targets are not identified.
-
When used in combination with surgery or radiation.
When Targeted Therapy Is Preferred
-
When cancer has a known genetic mutation.
-
For patients who cannot tolerate chemotherapy side effects.
-
In cancers like lung, breast, or colorectal cancer with identifiable molecular markers.
