5 Reasons Why NOW is the time for Precision Oncology

Precision oncology has reached a pivotal moment in its evolution, driven by various factors and advancements in technology. This transformative approach to cancer care is gaining momentum and holds the potential to revolutionize treatment outcomes. In this blog post, we will explore five compelling reasons why the time is ripe for precision oncology to flourish.


1. Patient and Physician Dissatisfaction with Non-Specific Approaches

Conventional cancer treatments often come with significant toxicity, leading to dissatisfaction among patients and physicians alike. Many patients fear chemotherapy due to its historical portrayal in media, and the side effects can be daunting. However, advancements in supportive care and the introduction of less invasive treatment options, such as targeted radiation therapy and minimally extensive surgeries, are reshaping the landscape. Precision oncology offers hope by tailoring treatments based on the unique biology of each patient’s tumor, minimizing unnecessary toxicity, and maximizing the potential for successful outcomes.

2. More Targeted Therapies

Targeted therapies, designed to address specific molecular alterations or abnormalities in cancer cells, are rapidly advancing. Early successes like trastuzumab (Herceptin) for breast cancer and imatinib (Gleevec) for chronic myelogenous leukemia have paved the way for more targeted treatment options.

In the past, cancer drugs were identified by testing cell lines and determining which drugs effectively killed cancer cells. Determining how they work to kill cancer cells was secondary. The more modern approach to discover cancer drugs is to identify a process or a molecular mechanism that encourages cancer cell growth and proliferation, then to find a drug that inhibits that specific mechanism. This shift from testing drugs on cancer cell lines to understanding and inhibiting specific molecular mechanisms has revolutionized drug development. Diagnostic tests that identify the presence of specific molecular alterations further aid in selecting the most appropriate targeted therapies.

3. The Rise of Immunotherapy

Immunotherapy has emerged as a game-changer in cancer treatment, offering renewed hope for patients. Ongoing research and clinical trials continue to optimize immunotherapy approaches, including the identification of biomarkers that predict treatment response and the development of strategies to overcome resistance mechanisms. Immunotherapy has significantly expanded the treatment landscape and is becoming an integral part of precision oncology.

4. Biomarker Integration in Clinical Trials

With improved understanding of cancer biology and diagnostic capabilities, clinical trials are evolving to incorporate biomarkers in their design. Instead of randomizing patients, trials now assign treatments based on specific molecular alterations or biomarkers. This approach ensures that patients receive tailored treatments based on their individual tumor characteristics, enhancing the likelihood of positive outcomes and minimizing unnecessary exposure to ineffective therapies.

5. Diagnostic Test Development

The success of precision oncology has sparked a flurry of diagnostic test development. Commercially available tests can reliably distinguish aggressive tumors from slow-growing tumors, helping physicians make informed decisions about treatment de-escalation. Additionally, specific mutations can guide the selection of beneficial drugs, while pharmacogenomic tests predict harmful side effects. These advancements in diagnostic testing contribute to the efficient delivery of treatments, maximizing benefits while minimizing unnecessary interventions and potential toxicities.

In Summary

The convergence of patient and physician dissatisfaction, targeted therapies, immunotherapy breakthroughs, biomarker integration in clinical trials, and diagnostic test development has created a favorable environment for the rapid advancement of precision oncology. With ongoing technological advancements, such as those we will explore in our next blog entry, precision oncology is poised to revolutionize cancer care. The future holds immense promise, offering new avenues for improved treatment outcomes, increased patient satisfaction, and enhanced quality of life.
