The revolutionary shift from one-size-fits-all treatments to precision medicine, biomarker-driven therapies, and groundbreaking clinical trials
In the not-so-distant past, a cancer diagnosis often meant a one-size-fits-all approach to treatment, with therapies that couldn't distinguish well between cancer cells and healthy ones. Today, we're witnessing a revolutionary shift in how we understand, diagnose, and treat cancer—a transformation fueled by evidence-based approaches that leverage cutting-edge science to create personalized strategies for each patient.
The field of oncology is being reshaped by precision medicine, where treatments are tailored to the unique genetic makeup of both the patient and their tumor, delivering what many experts call "the right treatment, for the right patient, at the right time."
This revolution extends from the laboratory bench to the patient's bedside, with innovative clinical trials generating robust evidence about what works—and what doesn't. The American Cancer Society estimates that in 2025 alone, there will be over 2 million new cancer cases in the United States, making these advances more critical than ever 2 . As Dr. Thomas Flaig of the University of Colorado Cancer Center notes, "There have been dramatic changes in the way we think about and address the care of patients with bladder cancer"—a sentiment that echoes across virtually all cancer types 1 .
Tailored treatments based on genetic profiles
Evidence-based approaches to validate treatments
Better survival rates and quality of life
At the heart of modern oncology's transformation is what experts call precision medicine—an approach that uses information about a person's genes, proteins, and environment to prevent, diagnose, and treat cancer 2 . This represents a fundamental departure from traditional methods that primarily classified cancers by where they originated in the body.
The shift has been made possible by our growing understanding of biomarkers—molecular characteristics that can indicate normal or abnormal processes in the body, or how someone might respond to a particular treatment. As Lori J. Wirth, MD, from Mass General Cancer Center explains, "Thyroid cancers are poster children for precision oncology" 1 .
The evidence supporting precision oncology comes from a new generation of clinical trials that are themselves evolving to become more efficient and informative. Biomarker-driven trials represent a major paradigm shift from conventional approaches 3 .
These test a single targeted therapy on multiple cancer types that all share a common molecular feature, regardless of where the cancer originated in the body.
These evaluate multiple targeted therapies for a single cancer type, with different treatments assigned based on the specific molecular profile of each patient's tumor.
| Trial Design | Key Feature | When It's Used | Example |
|---|---|---|---|
| Basket Trial | Tests one drug on multiple cancer types sharing a common biomarker | When a specific molecular alteration is found across different cancer types | Testing a NTRK inhibitor on all solid tumors with NTRK fusions |
| Umbrella Trial | Tests multiple drugs on a single cancer type with different biomarkers | When a cancer type has multiple known molecular subtypes with different therapeutic targets | Lung cancer trial assigning different drugs based on EGFR, ALK, ROS1 status |
| Enrichment Design | Only enrolls patients with a specific biomarker | Strong evidence suggests only biomarker-positive patients will benefit | HER2-targeted therapy trial exclusively for HER2-positive patients |
The first half of 2025 has already yielded remarkable advances across multiple cancer types, with updates to the National Comprehensive Cancer Network (NCCN) Guidelines reflecting these practice-changing developments 1 .
In bladder cancer, the approval of nogapendekin alfa inbakicept-pmln plus BCG for high-risk disease represents a significant advancement for patients unresponsive to standard therapy. Additionally, fam-trastuzumab deruxtecan-nxki (T-DXd) has emerged as a preferred treatment for HER2-positive advanced bladder cancer, demonstrating the power of biomarker-directed therapy 1 .
For neuroendocrine tumors, the CABINET trial led to FDA approval of cabozantinib, while the NETTER-2 study supported the use of lutetium Lu-177 dotatate as a first-line treatment for higher-risk tumors. According to Dr. Emily Bergsland of UCSF, "In terms of therapies, we have a number of new tools in the toolkit" 1 .
Beyond specific drug approvals, artificial intelligence (AI) is emerging as a transformative force across the entire cancer care continuum. AI-driven tools are now being deployed to enhance diagnostic accuracy, predict outcomes, and optimize treatment plans for individual patients 2 .
A deep-learning tool that detects homologous recombination deficiency in tumors using standard biopsy slides, identifying patients who may benefit from targeted treatments like PARP inhibitors with up to three times more accuracy than current genomic tests 2 .
Vanderbilt University's AI-powered tool that identifies microsatellite instability-high regions in tumors, potentially allowing more gastrointestinal cancer patients to benefit from immunotherapy 2 .
City of Hope's AI platform that assists physicians in summarizing patient histories, identifying clinical trial matches, and extracting data for research 2 .

|---|---|---|---|
| Lynozyfic | Relapsed/refractory multiple myeloma | Bispecific antibody | New option for patients who have exhausted multiple prior therapies |
| Linvoseltamab | Relapsed/refractory multiple myeloma | BCMA-targeted bispecific antibody | "Off-the-shelf" therapy with impressive response rates and safety profiles |
| Pivekimab sunirine | Blastic plasmacytoid dendritic cell neoplasm (BPDCN) | Antibody-drug conjugate targeting CD123 | First-in-class treatment for a rare, aggressive leukemia |
| Fam-trastuzumab deruxtecan-nxki | HER2-positive advanced bladder cancer | Antibody-drug conjugate | Biomarker-directed therapy regardless of previous treatment |
Anaplastic thyroid cancer is one of the most aggressive malignancies known, with most patients surviving less than a year after diagnosis. For those whose tumors harbor a specific genetic mutation called BRAF V600E, the prognosis has been particularly poor, as the disease is often diagnosed when it's already advanced and cannot be surgically removed.
In 2025, researchers at MD Anderson Cancer Center presented remarkable results from a Phase II clinical trial at the American Society of Clinical Oncology (ASCO) Annual Meeting that may change this dire outlook 6 . The study investigated a novel approach using targeted therapies before surgery—a concept known as neoadjuvant therapy—specifically for patients with Stage IV BRAF V600E-mutated anaplastic thyroid cancer.
Researchers enrolled patients with Stage IV BRAF V600E-mutated anaplastic thyroid cancer, confirming the mutation through comprehensive genomic testing.
Patients received a three-drug combination called DTP, consisting of:
After neoadjuvant treatment with the DTP combination, patients underwent surgery to remove any remaining cancer.
Researchers assessed multiple endpoints, including:
The results, presented by Dr. Mark Zafereo, were striking. An unprecedented two-thirds of patients had no residual anaplastic thyroid cancer after the neoadjuvant DTP treatment and subsequent surgery 6 . This represents a dramatic improvement over historical averages where successful surgical resection was often impossible in this patient population.
Perhaps even more importantly, these patients achieved an overall two-year survival rate of 69%—remarkable for a cancer type where survival is typically measured in months 6 .
| Outcome Measure | Result | Comparison to Historical averages |
|---|---|---|
| Rate of no residual cancer | 66% (2/3 of patients) | Significantly higher than previous approaches |
| Two-year overall survival | 69% | Typically <20% with conventional treatment |
| Treatment approach | Neoadjuvant DTP followed by surgery | Previously: immediate surgery often not possible |
Behind every cancer breakthrough is a suite of sophisticated research tools that enable scientists to probe the mysteries of cancer biology. These reagents form the foundation of the evidence-based approach in modern oncology research, allowing researchers to ask critical questions about how cancer cells behave, why they resist treatments, and how they can be selectively eliminated 8 .

As we look ahead, several emerging trends promise to further transform cancer care:
AI is poised to revolutionize how we interpret complex cancer data. As noted in recent reviews, "AI-driven tools are being used to enhance diagnostic accuracy, predict outcomes, and optimize treatment plans for individual patients" 2 .
A new generation of clinical trials focuses on intercepting cancer at its earliest stages, often by detecting and treating molecular residual disease (MRD)—cancer-derived biomarkers detectable through highly sensitive liquid biopsies .
As genomic sequencing and other technologies become more affordable and widespread, evidence-based oncology will become accessible to more patients worldwide.
The future of oncology lies in continuing to build a robust evidence base while ensuring these advances benefit all patients. As Nicolas Ferreyros of the Community Oncology Alliance notes, addressing key components of health equity and social determinants of health remains critical in cancer care 5 .
The transformation of oncology from a one-size-fits-all approach to a precision, evidence-based science represents one of the most significant medical advances of our time.
Through rigorous clinical trials, sophisticated biomarker development, and innovative research tools, we're building an unprecedented understanding of cancer biology that is directly translating into better outcomes for patients.
The evidence-based approach ensures that each new treatment advance rests on a foundation of robust scientific data, carefully generated and validated through well-designed studies. From the dramatic improvements in aggressive cancers like anaplastic thyroid cancer to the development of sophisticated AI tools that help match patients with optimal therapies, the progress in oncology reflects the power of science to confront even the most complex challenges.
As we continue to unravel the mysteries of cancer at molecular level, the evidence-based approach will remain our most reliable guide, ensuring that today's promising leads become tomorrow's life-saving treatments. The future of oncology is not just about developing more drugs, but about developing smarter strategies—guided by evidence, powered by technology, and centered on the patient.
