Targeted Therapy vs Chemotherapy: Which is the better Treatment for Cancer?

When a person talks about treating cancer, the idea that comes to the mind is chemotherapy. It is one of the most common and effective methods to treat different cancers, which have been used during decades. Nevertheless, due to the development of medical science, newer therapies, such as targeted therapy, are altering the approach to cancer treatment.

The most discussed question that patients and their families raise is: What is better, targeted treatment or chemotherapy? It is not as simple as picking one or the other. The treatment options have their respective roles, advantages, and disadvantages, and the most appropriate option is determined by the particular patient and the nature of the cancer.

And shall we divide it up in a plain, colloquial manner?

Understanding Chemotherapy

Chemotherapy, commonly known as chemo, is a treatment that is used by killing the multiplying cells of the body. The cells of cancer multiply rapidly and this is the reason why they respond to chemotherapy. Nonetheless, it does not differentiate so well between malignant cells and normal fast-growing cells (such as those found in hair follicles, bone marrow, and the digestive tract).

This is why chemotherapy is usually linked with the side effects such as:

• Hair loss
• Nausea and vomiting
• Fatigue
• Higher chances of infections.

Irrespective of these side effects, chemotherapy is an effective and even life saving intervention. 

It comes in handy particularly in:

• Fast-growing cancers
• Blood cancers such as leukemia and lymphoma
• Cases where cancer has spread widely

What is Targeted Therapy?

A more modern innovation in cancer treatment is targeted therapy. Rather than attacking all the rapidly growing cells, it targets certain molecules or genetic mutations that promote cancer development.

Consider it in the following way: chemotherapy is a shot at a broad target and a precision strike is targeted therapy.

Targeted therapy works by:

• Blocking specific proteins that help cancer grow
• Preventing cancer cells from forming new blood vessels
• Interfering with signals that tell cancer cells to divide

Due to its greater accuracy, targeted therapy is less likely to have an effect on normal cells and this usually results into fewer side effects than chemotherapy.

The most frequent side effects can be:

• Skin changes
• Mild fatigue
• Diarrhoea
• Hypertension (in certain cases).

Targeted Therapy and Chemotherapy – Key Differences

The biggest difference is how they work.

Chemotherapy does not require special markers, it can be applied in most forms of cancer without special tests. On the other hand, targeted therapy involves determining a specific genetic mutation or markers in the tumor. That is why, before commencing specific treatment, such tests are important such as molecular profiling or biomarker testing.

Another major difference is tolerability. Targeted therapy patients usually can easily maintain normal daily activities as opposed to patients receiving chemotherapy, which may change.

Which is More Effective?

It is here that the nuances come in.

No universal solution exists. Targeted therapy has had impressive outcomes in certain types of cancer, particularly where a particular mutation is causing the condition. For example:

• HER2-positive breast cancer
• EGFR-mutated lung cancer
• Certain colorectal cancers

In such instances, targeted therapy may be very useful and even more effective than conventional chemotherapy.

Nevertheless, chemotherapy cannot be underestimated and in most circumstances it is the mainstay of cancer treatment. Certain types of cancer do not have any recognizable targets hence chemotherapy is the most suitable choice.

In most cases, physicians adopt a combined therapy method of chemotherapy and targeted therapy to obtain improved results.

Some Common Experiences of Patients

On the side of a patient, this may vary a lot.

The process of chemotherapy might be severe, as there are observable side effects throughout and following the chemotherapy. When administered as oral therapy, especially as targeted therapy, there may be less disruption to daily life.

However, one should keep in mind: fewer side effects does not mean none. Targeted therapy requires close monitoring and frequent follow-ups.

How do Doctors choose the Right Treatment?

The decision to follow chemotherapy or targeted therapy is based on the following factors:

• The type and stage of cancer
• Genetic profile of the tumor
• General health condition of the patient.
• Previous treatments
• Treatment objectives (curative vs. palliative)

That is why the treatment of cancer is tailored nowadays. Two patients with similar cancer might get totally different treatment plans based on their health parameters 

The Role of Personalised Cancer Care

Contemporary oncology is shifting towards personalized or precision medicine. In place of treating cancer just by its location (i.e. lung or breast), we now examine the biology of the tumor.

This strategy assists in:

• Choosing the most efficient treatment
• Minimising unwarranted side effects
• Improving overall outcomes

This change includes a lot of targeted therapy, which does not substitute chemotherapy but complements it.

Conclusion

Which is better then, targeted therapy or chemotherapy?

The truthful response is: neither is better than the other. The best treatment is that which is effective in your particular cancer.

The treatment with chemotherapy is still a reliable and effective method, and targeted therapy is the future of the precision care of cancer. In most instances, a combination of the intelligent use of the two has yielded the best outcomes.

In the event of a cancer diagnosis, the first thing you will want to do is to seek the assistance of a seasoned oncologist in Noida who can help you navigate the options and come up with a treatment plan that suits your needs.

Treatment of cancer has come far, and with a proper approach, the results are getting better day by day.
