What is molecular profiling and genomic testing?

Molecular profiling refers to laboratory analyses that identify genetic, epigenetic, and molecular features of a tumor. These tests examine the tumor's DNA, RNA, proteins, or other biomarkers to reveal why a tumor behaves a certain way — why it grows, spreads, or responds (or does not respond) to therapy. Genomic testing specifically looks at the genetic alterations in tumor cells, including mutations, copy number changes, gene fusions, and other genomic events.

In practical terms, molecular profiling may involve:

• Next-generation sequencing (NGS) to sequence many genes at once.
• Comprehensive genomic profiling (CGP) that covers hundreds of genes relevant to cancer.
• Targeted panels focusing on specific oncogenes or tumor suppressor genes (EGFR, ALK, KRAS, BRCA, etc.).
• Liquid biopsy (ctDNA) testing that sequences circulating tumor DNA in blood.
• Immunohistochemistry (IHC) and FISH to test protein expression or gene rearrangements.

The goal of these tests is straightforward: to move from a one-size-fits-all approach to precision oncology — matching patients in Amritsar and across Punjab to therapies that target the specific biology of their cancer. Molecular profiling can identify actionable alterations that direct the use of targeted drugs, determine eligibility for immunotherapies, or help enroll patients in clinical trials. It also separates inherited (germline) genetic risks from somatic tumor changes — an important distinction for family counseling and surveillance.

Why molecular profiling matters in oncology

Cancer treatment has evolved rapidly. Whereas traditional chemotherapy targets fast-dividing cells in general, modern oncology increasingly relies on treatments tailored to a tumor's molecular drivers. Precision oncology aims to give the right drug, to the right patient, at the right time. This strategy improves outcomes, reduces unnecessary toxicity, and can prolong survival and quality of life.

Key reasons molecular profiling is critical:

• Identifies actionable targets: Mutations in EGFR, ALK, ROS1, BRAF, BRCA1/2, and others can be directly targeted with approved therapies.
• Guides immunotherapy use: Biomarkers like PD-L1, tumor mutational burden (TMB), and microsatellite instability (MSI) help predict response to immune checkpoint inhibitors.
• Predicts resistance: Secondary mutations that confer resistance to therapies can be detected early, allowing timely change of treatment.
• Enables clinical trial access: Many trials require specific genomic alterations for enrollment — profiling opens doors to novel treatments.
• Informs prognosis and surveillance: Certain molecular features correlate with prognosis and recurrence risk.

The impact is measurable. Globally, the move to biomarker-directed therapy has improved outcomes across multiple cancers — for example, targeted therapies for lung, breast, melanoma, and ovarian cancers have significantly increased progression-free and overall survival in selected patients. In India and Punjab, as molecular testing becomes more available through centres such as Livasa Amritsar, more patients can access these benefits locally without traveling to distant metropolitan centres.

Common tests and technologies: NGS, CGP, liquid biopsy and more

Several technologies are used for molecular profiling. Choosing the right test depends on the clinical question, type of cancer, available tissue, and turnaround time needed. Here are the commonly used tests and how they differ.

In many cases, a combination of tests is appropriate. For instance, a pathologist may perform IHC to screen for PD-L1 and then send tissue for a multi-gene NGS panel to identify actionable mutations. Liquid biopsy NGS is increasingly used in Punjab and Amritsar for monitoring residual disease or when repeat tumor biopsies are not feasible.

How molecular testing is performed at Livasa Amritsar

Livasa Amritsar follows a standardized, patient-centred workflow for molecular profiling that emphasizes quality, accuracy, and rapid communication of results. Below is a typical pathway from consultation to result and treatment planning.

• Initial oncology consultation: A medical oncologist reviews the diagnosis, staging, prior treatments, and discusses the potential benefits of genomic testing. This consultation determines the most appropriate testing strategy (targeted NGS panel, CGP, or liquid biopsy).
• Sample collection: Testing can use archived tumor tissue (formalin-fixed, paraffin-embedded blocks), fresh biopsy tissue, or a simple blood draw for liquid biopsy. Our pathology team ensures adequate material and preserves quality to reduce test failures.
• Laboratory processing: Samples are handled under strict chain-of-custody and quality control. For complex NGS/CGP, samples may be processed at our in-house molecular lab or partnered accredited labs providing validated oncology genomic testing in Punjab.
• Bioinformatics and reporting: Raw sequencing data are analyzed by specialized bioinformatics pipelines to identify mutations, fusions, and biomarkers. Results are reviewed by molecular pathologists and summarized in a clinician-friendly report with actionable recommendations.
• Multidisciplinary tumor board: At Livasa Amritsar, test results are discussed in a tumor board including medical oncologists, surgical oncologists, radiation oncologists, pathologists and genetic counselors when needed. This ensures individualized treatment planning.
• Patient counseling and follow-up: Results and implications are explained to patients and families in plain language. Genetic counseling is provided if a germline mutation is suspected, and follow-up testing or family screening is arranged.

For patients in Amritsar and nearby areas (including Ranjit Avenue, Model Town, Town Hall and surrounding districts), Livasa Amritsar offers same-day sample collection for many tests and coordinated care to streamline diagnosis-to-treatment timelines. If you are considering testing, request a consultation via Livasa appointment or call +91 80788 80788.

Who should get genomic testing and when

Not every patient with cancer needs the same test. Indications for testing depend on cancer type, stage, previous treatments, and family history. Below are common clinical scenarios where molecular profiling is strongly recommended.

• Advanced or metastatic disease: Most patients with stage IV cancers benefit from NGS testing to identify targeted therapy options.
• Recurrent tumors after standard therapy: Testing helps detect resistance mutations and alternative targeted agents.
• Specific tumor types: Non-small cell lung cancer (NSCLC), colorectal cancer, breast cancer (especially triple-negative), ovarian cancer, melanoma, pancreatic cancer, and certain head & neck and gastrointestinal cancers often require genomic profiling.
• Young patients or unusual presentations: Early-onset cancers or multiple primary tumors may indicate an inherited predisposition requiring germline testing (e.g., BRCA testing in Amritsar).
• When tissue is limited or repeat biopsy risky: Liquid biopsy (ctDNA) NGS testing offers a minimally invasive alternative to detect tumor DNA in blood.

Differentiating somatic tumor testing (changes that occur in cancer cells only) from germline genetic testing (inherited mutations present in all cells) is essential. Somatic testing directs targeted therapy for the individual, while germline results have implications for family members and future cancer risk management. At Livasa Amritsar, clinicians assess history and pathology to recommend the appropriate panel — and provide genetic counseling where germline risk is suspected.

Interpreting results and how they affect treatment decisions

A genomic report contains several types of findings: driver mutations (actionable), variants of uncertain significance (VUS), resistance mutations, and biomarkers like TMB and MSI. Translating these findings into treatment requires experienced oncologists and molecular tumor boards.

How results change care:

• Direct therapy selection: If an actionable mutation is found, approved targeted drugs can be used. Examples: EGFR inhibitors for EGFR-mutated lung cancer; PARP inhibitors for BRCA-mutated ovarian or breast cancer.
• Immunotherapy decisions: High TMB or MSI-high status may indicate a higher likelihood of response to immune checkpoint inhibitors.
• Avoid ineffective treatments: Knowing a tumor lacks a target prevents patients from receiving ineffective targeted agents and suffering unnecessary side effects.
• Resistance management: Detection of secondary mutations (e.g., T790M in EGFR) allows a switch to next-line targeted agents.
• Trial eligibility: Many clinical trials are biomarker-driven; profiling can unlock access to novel therapies when standard options are exhausted.

Reports often categorize alterations as Tier 1 (FDA/approved therapy available), Tier 2 (clinical evidence or guidelines support therapy), or Tier 3/4 (preclinical data or uncertain relevance). At Livasa Amritsar, our molecular pathologists annotate reports with recommended approved drugs, alternative therapies, and potential clinical trials in India and internationally.

Patients and families are encouraged to discuss the report thoroughly with their care team. If a germline mutation is identified, Livasa provides or arranges genetic counseling to discuss family testing, surveillance, and preventive strategies.

Cost, turnaround time and accessibility in Amritsar & Punjab

Cost and access are important considerations for patients choosing genomic testing. Prices vary by test complexity, provider, and whether testing is done in-house or sent to a reference lab. In Amritsar and across Punjab, options are expanding, but patients should understand typical price ranges, expected turnaround times, and insurance coverage possibilities.

These ranges are indicative and depend on panel complexity and the lab used. Insurance coverage is variable in India; some insurers partially cover testing if it directly affects treatment. Livasa Amritsar offers transparent pricing, guidance on financial assistance where available, and explains cost-effectiveness: in many cases, a targeted therapy identified through genomic testing may avoid multiple ineffective lines of chemotherapy, reducing overall cost and improving outcomes.

Accessibility: Historically, patients in smaller cities needed to travel to major metros for CGP and NGS testing. Today, Livasa Amritsar provides local access to high-quality oncology genomic testing in Amritsar and molecular profiling Punjab, reducing travel, delays, and logistical burdens for patients across districts surrounding Amritsar.

Comparing tissue biopsy vs liquid biopsy: which to choose?

One common decision is choosing between tumor tissue sequencing and liquid biopsy (circulating tumor DNA, ctDNA). Each approach has strengths and limitations. The table below summarizes the differences to help patients and clinicians choose the most appropriate test.

At Livasa Amritsar, clinicians often use both strategies complementarily: tissue NGS for initial comprehensive profiling and liquid biopsy NGS for dynamic monitoring or when tissue is not available. Our team recommends the most informative, least invasive approach depending on the individual case.
