Targeted Therapy for Cancer Treatment in Delhi

Targeted therapy for cancer is a modern, precision-based treatment approach that uses drugs to attack cancer cells while minimising damage to healthy tissues specifically. Unlike traditional chemotherapy, which affects many fast-growing cells in the body, targeted cancer treatment works by focusing on specific changes inside cancer cells that cause them to grow and spread.

Under the guidance of Dr. Satyendra Katewa, a leading paediatric haemato-oncologist in Delhi, patients receive evidence-based, personalised cancer treatment using targeted therapy. His expertise spans targeted therapy for blood cancer, leukaemia, lymphoma, and various solid tumours, ensuring safe and effective care for both children and adults.

What Is Targeted Therapy for Cancer and How Does It Work?

Targeted therapy works by identifying and attacking specific proteins, genes, or tissue environments that contribute to cancer growth and survival. These targeted drugs for cancer are designed to:

• Block signals that tell cancer cells to grow and divide
• Stop the formation of new blood vessels that feed tumours
• Trigger the immune system to destroy cancer cells
• Deliver toxic substances directly to cancer cells
• Prevent cancer cells from repairing themselves

This precision cancer therapy approach allows doctors to treat cancer more effectively while reducing side effects commonly seen with conventional treatments.

How Targeted Therapy Works in Cancer Treatment?

Targeted therapy identifies molecular markers on cancer cells and uses specialised drugs to interfere with their function. Here’s how the process works:

Molecular Testing: Genetic and molecular testing identify specific mutations or proteins in cancer cells that can be targeted with precision drugs.

Drug Selection: Based on test results, oncologists select targeted drugs that match the cancer’s specific molecular profile.

Treatment Administration: Targeted therapy is typically administered orally as tablets or by intravenous infusion, depending on the specific drug and the type of cancer being treated.

Monitoring Response: Regular scans and blood tests track how well the cancer responds to treatment, allowing adjustments as needed.

Dr. Katewa’s approach combines molecular targeted therapy with comprehensive diagnostic testing to ensure the most effective treatment plan for each patient.

Types of Targeted Therapy for Cancer

Targeted therapy offers multiple treatment options that focus on cancer cells with greater precision and fewer side effects than traditional chemotherapy.

Targeted Therapy for Blood Cancer

Blood cancers like leukaemia and lymphoma often respond well to targeted therapy. These treatments target specific genetic mutations and protein markers in blood cancer cells, offering better outcomes with fewer toxic side effects.

Targeted Therapy for Leukaemia

Leukaemia treatment has been transformed by targeted drugs that attack specific genetic abnormalities. Medications targeting BCR-ABL mutations in chronic myeloid leukaemia and FLT3 mutations in acute myeloid leukaemia have significantly improved survival rates and quality of life.

Targeted Therapy for Lymphoma

Targeted therapies for lymphoma treatment include drugs that target CD20 proteins on lymphoma cells, block growth signals, or enhance the immune response. These therapies are often combined with chemotherapy or used alone in relapsed cases.

Targeted Therapy for Solid Tumours

Solid tumours in organs like the lungs, breast, colon, and kidneys may also benefit from targeted therapy. Drugs targeting HER2, EGFR, VEGF, and other markers help control tumour growth and spread in specific cancer types.

By focusing on the unique biology of each cancer, targeted therapy offers more precise, effective, and better-tolerated treatment outcomes for both children and adults.

When Is Targeted Therapy Recommended?

Targeted therapy is considered when:

• Cancer cells have specific genetic mutations or protein markers
• Traditional chemotherapy has limited effectiveness
• The patient needs a treatment with fewer side effects
• Cancer has relapsed or is resistant to standard therapy
• Molecular testing shows targetable abnormalities

Common Conditions Treated

Targeted therapy can be used for cancers like :

• Chronic myeloid leukaemia (CML)
• Acute lymphoblastic leukaemia (ALL)
• Acute myeloid leukaemia (AML)
• Hodgkin and non-Hodgkin lymphoma
• Multiple myeloma
• Breast cancer with HER2 mutations
• Lung cancer with EGFR or ALK mutations
• Colorectal cancer with specific genetic markers
• Gastrointestinal stromal tumours (GIST)

Special Considerations for Children

Paediatric oncology has benefited greatly from targeted therapy. Dr. Satyendra Katewa, as a pediatric oncologist for targeted therapy, provides specialised care for children with blood cancers and solid tumours, using age-appropriate dosing and careful monitoring to ensure safety and effectiveness.

Diagnostic Tests Before Starting Targeted Therapy

Comprehensive testing ensures the right targeted therapy is selected for each patient’s unique cancer profile.

Tests Performed at Dr. Katewa’s Centre

Molecular and Genetic Testing: Next-generation sequencing (NGS), PCR testing, and fluorescence in situ hybridisation (FISH) to identify specific mutations, gene fusions, and chromosomal abnormalities.

Immunohistochemistry (IHC): Tests for protein markers like HER2, PD-L1, and CD20 that can be targeted with specific drugs.

Blood Tests: Complete blood count (CBC), liver and kidney function tests, and tumour markers to assess overall health and organ function.

Imaging Studies: CT scans, MRI, PET-CT, or ultrasound to determine cancer location, size, and spread.

Bone Marrow Evaluation: For blood cancers, bone marrow aspiration and biopsy help assess disease burden and response to treatment.

Liquid Biopsy: Advanced blood tests that detect circulating tumour DNA, useful for monitoring treatment response and detecting resistance.

This thorough evaluation at our advanced cancer treatment centre in Delhi ensures personalised, effective targeted therapy planning.

Step-by-Step Targeted Therapy Treatment Process

The targeted therapy treatment process is carefully planned and monitored to ensure safe, effective, and personalised cancer care at every stage.

1. Initial Consultation and Molecular Profiling

The journey begins with a detailed consultation where Dr. Katewa reviews medical history, previous treatments, and current health status. Tissue samples or blood tests are sent for comprehensive molecular profiling to identify targetable mutations.

2. Treatment Planning

Based on test results, a personalised treatment plan is created. This includes:

• Selection of appropriate targeted drugs
• Dosing schedule (daily oral medication or periodic infusions)
• Combination with other therapies if needed
• Expected duration of targeted therapy treatment
• Management plan for potential side effects

3. Treatment Administration

Oral Targeted Therapy: Many targeted drugs are taken as tablets at home, with regular follow-up visits to monitor response and side effects.

Intravenous Targeted Therapy: Some targeted drugs are given through IV infusion at the hospital or clinic, usually on an outpatient basis.

Treatment cycles vary depending on the drug type and cancer being treated. Some patients take targeted therapy continuously, while others follow specific cycles with breaks.

4. Monitoring and Follow-Up

Regular monitoring ensures treatment effectiveness and early detection of any issues:

Clinical Assessment: Physical examination and symptom evaluation during follow-up visits, typically every 2-4 weeks initially.

Blood Tests: Frequent CBC and organ function tests to monitor side effects and treatment response.

Imaging: Periodic scans (every 8-12 weeks) to assess tumour size and cancer spread.

Molecular Monitoring: Repeat genetic testing to check treatment response and detect resistance development.

Dr. Katewa’s team provides continuous support and adjusts treatment based on individual response and tolerance.

5. Long-Term Management

The duration of targeted therapy treatment varies. Some patients take targeted drugs for months, while others continue for years, especially if the cancer is well-controlled. Long-term management includes:

• Regular health monitoring
• Management of chronic side effects
• Lifestyle and dietary guidance
• Psychological support
• Surveillance for cancer recurrence

With expert monitoring and personalised planning, targeted therapy offers effective cancer control with fewer side effects and improved quality of life.

Targeted Therapy vs Chemotherapy India: Key Differences

Understanding the difference between these approaches helps patients make informed treatment decisions.

Aspect	Targeted Therapy	Chemotherapy
Precision and Selectivity	Attacks specific molecules or genetic markers on cancer cells while largely sparing healthy cells, leading to better precision and quality of life.	Destroys all rapidly dividing cells, including healthy cells such as hair follicles and gut lining, resulting in broader effects.
Side Effects Profile	Side effects are usually milder and may include skin rashes, diarrhoea, high blood pressure, changes in liver function, and fatigue; most are manageable with supportive care.	Side effects are often more intense and include hair loss, severe nausea and vomiting, mouth sores, bone marrow suppression, and higher infection risk.
Treatment Eligibility	Requires specific genetic mutations or protein markers; not suitable for all cancer types.	It can be used for most cancers regardless of genetic or molecular profile.
Treatment Duration	Often administered long-term as oral medicines or periodic infusions, sometimes continued for years if effective.	Typically given in defined cycles over several months, with rest periods between treatments.

Is Targeted Therapy Safer Than Chemotherapy?

While targeted therapy generally has fewer severe side effects than chemotherapy, “safer” depends on individual circumstances. Targeted therapy can cause unique side effects like heart problems, liver toxicity, or bleeding issues. Dr. Katewa evaluates each patient’s cancer profile, overall health, and treatment goals to recommend the safest and most effective approach.
