Targeted therapy forms the cornerstone of modern precision oncology. Unlike traditional chemotherapy, targeted therapies use specialized drugs formulated to pinpoint and block specific genetic mutations, proteins, or blood vessel signals essential for cancer cell growth and survival.
Understanding Targeted Therapy
Every tumor possesses unique molecular characteristics. Under the direction of Dr. Amit Saklani (MBBS, MD, DM Medical Oncology) in Jalandhar, advanced molecular biomarker testing (such as Next-Generation Sequencing, FISH, and PCR) is performed on biopsy tissues to identify exact genetic alterations. Targeted inhibitors are then chosen to "lock onto" those specific targets, effectively cutting off tumor growth signals while minimizing harm to surrounding healthy tissues.
Key Types of Targeted Therapy
Targeted oncology treatments function through distinct molecular mechanisms:
- Small Molecule Inhibitors: Oral medications (Tyrosine Kinase Inhibitors / TKIs) small enough to enter cancer cells and disrupt internal growth signals (e.g. Osimertinib, Gefitinib, Erlotinib, Alectinib).
- Monoclonal Antibody Targets: IV biological drugs engineered to bind to external receptors on cancer cell surfaces (e.g. Trastuzumab/Herceptin for HER2, Cetuximab for EGFR).
- Angiogenesis Inhibitors: Medications (e.g. Bevacizumab) that block VEGF signals, preventing tumors from growing new blood vessels and starving them of oxygen and nutrients.
- Hormone Receptor Blockers: Specialized therapies that inhibit estrogen or androgen receptors driving hormone-sensitive cancers.
Molecular Biomarker Testing Before Treatment
Before prescribing targeted therapy, Dr. Saklani conducts comprehensive molecular testing for drivers like EGFR, ALK, ROS1, BRAF, HER2, and BRCA to select the exact precision agent proven to yield maximum tumor response.
Targeted Therapy vs. Traditional Chemotherapy
- Higher Specificity: Targeted agents focus exclusively on altered cancer proteins, sparing healthy blood cells and organs.
- Oral Convenience: Many targeted inhibitors are taken as daily oral tablets at home under outpatient monitoring.
- Reduced Side Effects: Eliminates classic chemo side effects like severe hair loss, extreme nausea, and severe bone marrow suppression.
