What is precision medicine, and how is it different from standard of care treatment

Precision Medicine vs. Standard of Care Treatment

What Is Precision Medicine?

Precision medicine (also called personalized medicine) is an approach where treatment is tailored to the individual characteristics of each patient's cancer—rather than using a one-size-fits-all approach.

Instead of: "All patients with lung cancer get chemotherapy X"

Precision medicine asks: "What specific mutations does THIS patient's cancer have? What treatment will work best for THEIR tumor?"

How They Differ

| Standard of Care | Precision Medicine | |---|---| | Based on cancer type and stage | Based on cancer type, stage, AND genetic mutations | | Same treatment for most patients | Customized based on tumor biology | | Proven effective in large populations | Targeted to individual tumor characteristics | | Established, well-tested protocols | May include newer targeted drugs or combinations | | Often chemotherapy-based | Often includes targeted therapy or immunotherapy |

A Practical Example

Standard of Care for Stage 3 Lung Cancer: Chemotherapy + radiation therapy (proven effective for most patients)

Precision Medicine Approach:

• Test shows EGFR mutation → Use EGFR inhibitor (targeted drug)
• Test shows PD-L1 high expression → Use immunotherapy
• Test shows KRAS mutation → Use KRAS inhibitor + chemotherapy
• Test shows no actionable mutations → Standard chemotherapy may be best option

Why Precision Medicine Matters

According to NCCN Guidelines and ASCO recommendations, precision medicine can:

1. Improve outcomes - Targeted drugs often work better than chemotherapy for specific mutations
2. Reduce side effects - Targeted therapies may cause fewer side effects than broad chemotherapy
3. Identify clinical trials - Genomic results can match you with trials testing new drugs for your specific mutation
4. Avoid ineffective treatments - Skip drugs unlikely to work for your specific cancer

The Reality: It's Often Both

In modern oncology, standard of care increasingly includes precision medicine elements. Your doctor likely uses both:

• Standard protocols as the foundation (proven, evidence-based)
• Precision testing (genomic sequencing) to personalize within that framework
• Targeted drugs when mutations are found that have FDA-approved treatments

According to the American Cancer Society, genomic testing is now standard practice for many cancer types, including:

• Lung cancer
• Breast cancer
• Colorectal cancer
• Melanoma
• Leukemias and lymphomas

Questions to Ask Your Oncologist

1. Is genomic testing recommended for my cancer type?
2. What does "standard of care" mean for my specific diagnosis?
3. Are there precision medicine options available for my cancer?
4. If my tumor has specific mutations, what targeted treatments exist?
5. Are there clinical trials I might be eligible for based on my tumor's genetics?

Important Context

Precision medicine isn't always "better"—it's different and individualized. Sometimes standard chemotherapy is the most effective option. Your oncologist will determine the best approach based on:

• Your specific cancer type and stage
• Available genomic test results
• Your overall health
• Proven effectiveness for YOUR situation
