Targeted Therapy vs Chemotherapy

Targeted Therapy vs Chemotherapy

The diagnosis of cancer turns everything in a moment. Flooding with questions, along with the emotional shock, come the questions: What treatment will I need? Will it be chemotherapy? Is there a better option? I heard of targeted therapy. What does that mean?

Today, treatment is no longer the same for every patient. The new developments in the medical science field enable oncologists to research the specific biology of a particular tumor and select more effective and fewer side effect treatments. Learning the difference between targeted therapy and chemotherapy may enable patients and families to feel more informed, less anxious and more confident about their treatment.

Earlier, chemotherapy was the primary treatment. Although it is very effective, it has been discovered that cancers do not behave at the molecular level.

Two cancer patients of the same kind might react differently to the same treatment.

What is chemotherapy?

Chemotherapy uses powerful drugs to kill cancerous cells. These drugs act by attacking cells that grow and divide rapidly, which is a major characteristic of cancer. Since chemotherapy travels through the bloodstream, it can treat cancer cells throughout the body.

It is helpful in cases of:

• Advanced cancers
• Fast growing tumors
• Cancers that have spread beyond the primary site

Nevertheless, chemotherapy is unable to recognize the difference between the cancer cells and some of the normal rapidly growing cells.

As a result, it may affect:

• Hair follicles
• Bone marrow
• Tissues which line the digestive tract

There are patients who experience:

• Hair loss
• Fatigue
• Nausea
• Vomiting
• Low immunity
• Loss of appetite

What is targeted therapy?

One of the largest achievements in cancer therapy is targeted therapy. It does not attack all the cells that develop fast. Rather, it targets certain genes, proteins and pathways that contribute to the growth and expansion.

Each cancer has a unique biological signature. Some tumors contain specific mutations and receptors that act as growth switches. Targeted therapy works by blocking these signals, slowing and stopping the growth and spread.

The new technique is one of the major aspects of modern targeted cancer treatment in Hyderabad, in which a molecular test is used to determine the best treatment for each patient.

Difference Between Targeted Therapy and Chemotherapy

Both treatments aim to destroy cancer, their approach is different.

Chemotherapy:

• Grows on all rapidly growing cells
• Works with most types of cancer
• Applicable in the case of spreading it
• May have more diverse side effects

Targeted Therapy:

• Only works on distinct cancer markers
• Personalized and precise
• Often better tolerated
• Only effective in case the tumor has a target

In most cases, physicians can also prescribe the combination of chemotherapy and targeted therapy to get better results.

How Doctors Decide the Best Treatment

The decision on whether to use targeted therapy or chemotherapy depends on several factors, among which are

• Type and stage
• Tumor size and spread
• Molecular/genetic profile
• Age and general health of the patient
• Treatment goals

Oncologists can prescribe complex tests like

• Biopsy and histopathology
• Immunohistochemistry
• Molecular testing
• CT scan, MRI and PET scan

The tests can be used to identify that the targeted therapy would be effective and enable the doctor to develop an individual form of treatment.

Side Effects: What Patients Should Know

Understanding possible side effects helps patients prepare mentally and physically.

Chemotherapy side effects

• Hair loss
• Fatigue
• Nausea
• Low blood counts
• High risk of infections

Targeted therapy side effects

• Skin changes
• Rash
• Diarrhea
• Fatigue
• Blood pressure changes
• Mild fever
• Thyroid issues

Targeted therapy is more selective and therefore, most of the patients can resume their normal activities with minimum disturbances. Followups are done regularly to have the side effects managed on time.

Benefit from Targeted Therapy?

Targeted therapy only works when there are particular molecular markers. It is commonly used in:

• HER2 -positive breast cancerE
• EGFR/ALK -mutated lung cancer
• Colorectal cancer
• Leukemia and lymphoma
• Kidney and Thyroid cancer

If these targets are not present, chemotherapy, immunotherapy and other treatments may be more appropriate.

A New Era of Care

The comparison of targeted therapy vs chemotherapy is not about choosing one over the other. It is a choice of appropriate treatment according to the biology of the cancer and the needs of the patient.

Patients nowadays have more effective, safer and personalized treatment options than ever before with improved precision medicine using the available accessible expert oncologists.

Seeking the professional advice of such a specialist as Dr. G. Vamshi Krishna Reddy, patients are evaluated and examined thoroughly and offered individual treatment plans that aim to bring the most possible outcomes.

A Reassuring Final Thought

Cancer treatment has come a long way. What was previously overwhelming has been directed by science, precision and experience. The timely diagnosis, appropriate treatment strategy and qualified care may result in a substantial difference in the recovery and the quality of life.

Consult the experienced medical oncologist that will make you know your options clearly and proceed with confidence, hope and the assurance that you are on the right path toward recovery.
