Precision Medicine

Precision medicine is an approach to healthcare that considers the individual characteristics of a patient and their disease to help guide treatment decisions. In cancer care, it may involve examining the tumour's genetic changes, molecular features, and relevant biomarkers to identify treatment options that are more suitable for a particular patient.

Patients searching for Precision Medicine in Faridabad may benefit from consulting a medical oncology specialist who can review their diagnosis, pathology reports, and molecular test results. Precision medicine can help doctors understand why certain cancers grow, identify potential treatment targets, and determine whether specific targeted medicines or other therapies may be appropriate.

Dr. Ashish B. Agrawal is a Medical Oncologist, Haematologist, and Bone Marrow Transplant (BMT) specialist. A specialist consultation can help patients understand the role of precision medicine in their cancer treatment plan, the tests that may be needed, and the potential benefits and limitations of personalised treatment.

What Is Precision Medicine?

Precision medicine is a healthcare approach that uses information about a person's disease and other relevant characteristics to support individualised medical decisions. In oncology, it focuses on the biological features of a tumour rather than relying only on its location in the body.

For example, two patients may have cancer in the same organ but have different molecular changes. These differences may influence how their cancers behave and which treatments are appropriate.

Precision medicine may involve:

• Genetic or molecular testing of tumour tissue
• Biomarker testing
• Review of pathology and cancer staging
• Evaluation of inherited cancer-related genetic changes when indicated
• Selection of targeted treatments for specific molecular alterations
• Monitoring treatment response and disease progression

Precision medicine does not guarantee that a targeted treatment will be available or effective for every patient. Test results must be interpreted alongside the cancer type, stage, overall health, and current clinical evidence.

How Precision Medicine Is Used in Cancer Treatment

Precision medicine can help oncologists make informed decisions at different stages of cancer care. It may be used during the initial evaluation, when selecting treatment for advanced cancer, or when a cancer progresses despite previous therapy.

1. Understanding the Tumour's Molecular Profile

Cancer cells can develop genetic and molecular changes that influence their growth and survival. Molecular profiling can help identify certain changes that may be relevant to treatment selection.

The type of testing depends on the cancer diagnosis and the clinical question being investigated.

2. Identifying Potential Treatment Targets

Some cancers have specific molecular alterations that can be targeted by particular medicines. When an appropriate target is identified and a suitable treatment is available, the oncologist can assess whether it is appropriate for the patient.

Not every molecular alteration has an approved or effective treatment, and not every patient with a particular alteration will respond in the same way.

3. Supporting Treatment Decisions

Precision medicine results may help doctors consider targeted therapy, immunotherapy in selected settings, standard cancer treatments, or participation in a suitable clinical trial.

The results are interpreted together with established treatment guidelines and the patient's medical condition.

4. Reviewing Treatment Options When Cancer Progresses

Some cancers develop additional molecular changes over time. When clinically appropriate, repeat testing may help explain treatment resistance or identify new treatment options.

Repeat testing is not necessary for every patient. The oncologist decides whether it is likely to provide useful information.

Types of Tests Used in Precision Medicine

The choice of tests depends on the cancer type, available tissue, previous investigations, and the treatment decisions being considered.

1. Tumour Genetic Testing

Tumour genetic testing looks for changes in the DNA of cancer cells. It may identify alterations that are relevant to prognosis, classification, or treatment selection.

Testing can be performed on tumour tissue and, in selected circumstances, other sample types.

2. Next-Generation Sequencing (NGS)

Next-generation sequencing is a technology that can examine multiple genes or genetic alterations in a single test. In oncology, it may be used to identify molecular changes that could guide treatment decisions.

NGS is not required for every cancer. Its usefulness depends on the diagnosis, clinical stage, treatment options, and whether the results are likely to change management.

3. Biomarker Testing

Biomarkers are measurable features of a tumour or the body that can provide information about disease characteristics or potential treatment response.

Depending on the cancer, testing may include markers such as HER2, EGFR, ALK, BRAF, PD-L1, or mismatch repair and microsatellite instability status. These are examples only; the appropriate tests vary significantly between cancer types.

4. Germline Genetic Testing

Germline testing examines inherited genetic changes that may be associated with an increased risk of certain cancers. It may be recommended when personal history, family history, or specific cancer characteristics suggest an inherited cancer predisposition.

Inherited genetic testing can have implications for biological relatives. Genetic counselling may be useful before and after testing to explain the possible results and their implications.

5. Liquid Biopsy

A liquid biopsy analyses material, such as circulating tumour DNA, found in a blood sample. In selected situations, it may provide information about tumour-related genetic changes when tissue testing is not possible or when additional molecular information is needed.

Liquid biopsy has limitations. A negative result does not always exclude a relevant tumour alteration, and tissue testing may still be necessary.

6. Pathology and Immunohistochemistry

Pathology examination helps establish the cancer diagnosis. Immunohistochemistry uses antibodies to identify specific proteins in tissue and can help classify tumours or assess biomarkers relevant to treatment selection.

These investigations may be used alongside molecular tests to build a clearer picture of the disease.

Which Cancers May Benefit From Precision Medicine?

Precision medicine is used in many areas of cancer care, although its role varies according to the type and stage of cancer.

Examples include:

• Lung cancer: Molecular testing may identify changes such as EGFR mutations or ALK rearrangements that can guide treatment in eligible cases.
• Breast cancer: Biomarkers such as hormone receptor status and HER2 status help determine suitable treatment approaches.
• Colorectal cancer: Molecular markers can help guide selected treatment decisions, including the use of certain targeted medicines.
• Gastrointestinal cancers: Molecular testing may help identify treatment options for specific tumour subtypes.
• Melanoma: Certain molecular alterations, including BRAF changes in eligible cases, may guide targeted treatment.
• Ovarian cancer: Selected patients may benefit from testing for inherited or tumour-related alterations that influence treatment decisions.
• Prostate cancer: Molecular or inherited genetic testing may be relevant for selected patients, particularly in certain advanced disease settings.
• Blood cancers and lymphomas: Specific genetic and molecular findings can assist with disease classification, risk assessment, and treatment selection.

These examples do not mean that every patient with these cancers needs comprehensive molecular profiling. The treating specialist determines which investigations are appropriate.

Benefits of Precision Medicine

When used appropriately, precision medicine can provide useful information to support cancer treatment decisions.

Potential benefits include:

• More informed treatment selection: Molecular findings may help identify therapies relevant to a patient's tumour.
• Better understanding of tumour biology: Testing can reveal characteristics that influence how a cancer behaves.
• Identification of treatment targets: Certain results may indicate whether a targeted medicine is a suitable option.
• Support for personalised care planning: Results can be considered alongside the patient's medical history and treatment goals.
• Information for selected clinical trials: Some molecular findings may help determine eligibility for a relevant research study.
• Additional insight in selected cases: Testing may help inform decisions when cancer progresses or responds poorly to previous treatment.

The benefits depend on the accuracy and relevance of the tests, the availability of suitable treatments, and the clinical context. Precision medicine cannot guarantee a cure or a successful response.

Precision Medicine vs Conventional Cancer Treatment

Precision medicine and conventional cancer treatments are not mutually exclusive. Precision medicine helps guide decisions about treatment, while conventional treatments such as surgery, chemotherapy, radiation therapy, hormonal therapy, immunotherapy, and targeted therapy remain important parts of cancer care.

In modern oncology, precision medicine often complements standard treatment rather than replacing it.

Who Should Consider Precision Medicine?

Precision medicine may be worth discussing with an oncologist if:

• You have a cancer type for which molecular or biomarker testing is recommended.
• You have advanced or metastatic cancer and testing could influence treatment selection.
• Your cancer has progressed after previous treatment.
• Your pathology report suggests a particular biomarker or molecular alteration.
• Your personal or family history raises concerns about inherited cancer risk.
• Your oncologist believes molecular profiling may help clarify treatment options.

Testing is not always beneficial or necessary. It should be considered when the result could meaningfully inform diagnosis, treatment, or risk assessment.

What to Expect During a Precision Medicine Consultation

A consultation usually begins with a review of the cancer diagnosis, medical history, previous treatments, and available reports.

The specialist may discuss:

1. Reviewing the diagnosis: Understanding the cancer type, stage, and pathology findings.
2. Assessing the need for testing: Determining whether tumour profiling, biomarker testing, or inherited genetic testing is appropriate.
3. Choosing a suitable sample: Establishing whether existing tissue is sufficient or another sample may be needed.
4. Interpreting the results: Explaining which findings are clinically relevant and which may not affect treatment.
5. Discussing options: Reviewing available standard treatments, targeted therapies, clinical trials, and other appropriate approaches.
6. Planning follow-up: Monitoring the disease and reassessing treatment options when needed.

Patients should bring their pathology reports, imaging results, previous molecular tests, treatment records, and current medication list to the consultation.

Limitations of Precision Medicine

Although precision medicine has improved treatment selection in many areas of oncology, it has important limitations.

• Testing may not identify an actionable molecular alteration.
• Some results may have uncertain clinical significance.
• A suitable targeted treatment may not be available or accessible.
• A treatment that targets a particular alteration may not work for every patient.
• Tumours can change over time and develop resistance to treatment.
• Some tests can be costly and may not be covered by every health plan.
• Testing results need to be interpreted by qualified professionals in the context of the full diagnosis.

A molecular test result should never be interpreted in isolation. Treatment decisions should consider clinical evidence, the patient's preferences, and the potential benefits and risks of the available options.
