New Cancer Treatment Breakthroughs (2026 Update): The Biggest Advances Changing Cancer Care

Medically framed guide · Last updated July 20, 2026 · Originally published May 2026

Quick Answer

The most consequential 2026 cancer breakthrough is daraxonrasib, an oral RAS(ON) inhibitor that nearly doubled overall survival in previously treated metastatic pancreatic cancer in the phase 3 RASolute 302 trial presented at ASCO 2026. Other major advances include the OPTIMA trial, showing many high-risk breast cancer patients can safely skip chemotherapy after genomic testing; the bispecific antibody ivonescimab, which outperformed standard immunotherapy in squamous lung cancer; continued expansion of CAR-T and cell therapies into solid tumors; and growing, evidence-tiered interest in repurposed drugs and metabolic approaches as complementary strategies. AACR 2026 and ASCO 2026 both emphasized that progress is driven by combining precision diagnostics, immunotherapy, and targeted agents — not a single cure.

Cancer remains one of the world's largest health burdens. According to Global Cancer Statistics 2024, published jointly by the American Cancer Society and the International Agency for Research on Cancer (IARC) in July 2026, roughly 21 million people were diagnosed with cancer and close to 9.8 million died from the disease worldwide in 2024 — a toll the World Health Organization says is projected to nearly double to about 35 million annual cases by 2050 without stronger prevention and access to care.1,2 Despite the scale of that burden, cancer research continues to advance at an unprecedented pace, and 2026 has already produced some of the most consequential randomized trial results in years.

The 2026 American Association for Cancer Research (AACR) Annual Meeting took place in San Diego from April 17–22 and reflected how cancer research continues to evolve. A central theme was the idea of cancer as more than a collection of tumor cells — it is shaped by a complex ecosystem of immune cells, surrounding tissue, metabolism, and even the microbiome, all interacting dynamically. Six weeks later, the 2026 ASCO Annual Meeting (May 29–June 2, Chicago) delivered what oncologists are already calling some of the most consequential plenary data in years, including practice-changing results in pancreatic, breast, and lung cancer that are woven throughout this update.

As we move through 2026, several groundbreaking therapies and innovations — next-generation immunotherapy, RAS-targeted drugs, gene-editing technologies, repurposed drugs, and alternative cancer treatments — are reshaping cancer care. Here is what the evidence actually shows.

1. Next-Generation Immunotherapies

Perhaps the most transformative development in modern oncology has been the rise of immunotherapy — treatments that awaken the immune system to recognize and attack cancer rather than attacking cells indiscriminately. Checkpoint inhibitors, CAR-T cell therapies, and bispecific antibodies continue to expand treatment options for hard-to-treat cancers, including pancreatic and brain tumors, and intra-tumoral immunotherapy is emerging as a way to convert accessible tumors like melanoma into an "in situ vaccine," although consistent systemic responses in visceral metastases remain a challenge.

Checkpoint Inhibitors

Checkpoint inhibitors were the first major triumph in this domain. Cancers like melanoma, lung cancer, and Hodgkin's lymphoma once carried grim prognoses; drugs such as nivolumab, pembrolizumab, and atezolizumab have since produced durable responses, and sometimes complete remission, by blocking the molecular "brakes" cancer places on immune cells.

CAR-T Cell Therapy: Durable Remissions and an Updated Safety Picture

CAR-T cell therapy harvests a patient's T-cells, engineers them to recognize a cancer-specific antigen, and infuses them back into the bloodstream, where they become targeted hunters. In blood cancers like B-cell leukemia, CAR-T has produced cure rates above 80% in patients who had exhausted every other option. In 2022, Nature reported that two of the first patients ever treated with CAR-T remained in remission 12 years later; more recently, the journal profiled a woman treated with CAR-T as a four-year-old who is still in remission 19 years on.

The safety picture has also evolved. After the FDA identified postmarketing reports of secondary T-cell malignancies in patients who had received CAR-T therapy, the agency required a class-wide boxed warning on all approved CAR-T products, a labeling update finalized in 2024. Subsequent systematic reviews and meta-analyses suggest the absolute risk of a secondary malignancy is small relative to CAR-T's survival benefit, and oncologists report the warning has not meaningfully changed how often they recommend the therapy, though lifelong monitoring for new malignancies is now standard practice.

A key theme at AACR 2026 was understanding why immune responses fail even when immune cells reach the tumor: tumors can push infiltrating cells into a dysfunctional state, reframing resistance as potentially reversible rather than fixed. The AACR-ASCO Joint Session highlighted ongoing efforts to extend CAR-T into solid tumors — glioblastoma, pancreatic cancer, and ovarian cancer trials are underway, with engineered cells augmented by "logic gates" and "safety switches" designed to spare healthy tissue.

ASCO 2026 Update: A Bispecific Antibody Beats Standard Immunotherapy in Lung Cancer

One of the defining ASCO 2026 plenary results involved ivonescimab, a first-in-class bispecific antibody that simultaneously targets PD-1 and VEGF in a single molecule — pairing immune checkpoint blockade with anti-angiogenic activity. In the phase 3 HARMONi-6 trial of 532 patients with advanced squamous non-small cell lung cancer, ivonescimab plus chemotherapy produced a median overall survival of roughly 27.9 months versus 23.7 months for the established regimen of tislelizumab (a PD-1 inhibitor) plus chemotherapy — about a one-third reduction in the risk of death — and the benefit held regardless of PD-L1 expression level.3 It was also the first China-originated oncology drug ever featured in an ASCO plenary session in the society's history. Independent analysts have cautioned that the trial population was entirely Chinese, so it remains unclear how the results will generalize globally, and additional "HARMONi" trials in broader populations are underway.

Immunotherapy vs. Chemotherapy: A Shrinking Role for Cytotoxic Drugs

Chemotherapy still saves lives and remains essential in many settings, but for a growing number of cancers it is no longer the default. Melanoma specialist Dr. Daniel Flora has noted on Substack that he has not prescribed chemotherapy for melanoma in years, relying instead on immunotherapy, targeted therapy, and clinical trials of newer approaches such as bispecific T-cell engagers and tumor-infiltrating lymphocyte therapy.4 Across oncology more broadly, chemotherapy has moved from first-line default to a more selective tool in cancers including:

  • Melanoma — immunotherapy and targeted treatments are now the primary tools
  • Chronic myeloid leukemia (CML) — oral tyrosine kinase inhibitors like imatinib allow near-normal lifespans without chemotherapy
  • Chronic lymphocytic leukemia (CLL) — targeted drugs like venetoclax and BTK inhibitors are commonly first-line
  • MSI-High colorectal and endometrial cancers — immunotherapy can provide long-lasting responses in mismatch-repair-deficient tumors
  • ER-positive breast cancer with a low Oncotype DX score — hormonal therapy alone is often sufficient
  • PD-L1-high non-small cell lung cancer — single-agent immunotherapy may outperform chemotherapy in selected patients
  • Advanced prostate cancer — hormone-targeting agents like enzalutamide and abiraterone are now often preferred
  • Kidney cancer — most patients now receive immunotherapy and VEGF inhibitors rather than chemotherapy
  • Liver cancer (HCC) — atezolizumab plus bevacizumab is now a standard first-line combination
  • Multiple myeloma — treatment increasingly starts with monoclonal antibodies and other targeted agents

Chemotherapy still matters where the evidence supports it, especially when it improves cure rates, and clinicians generally reach for a clinical trial or a more targeted option first whenever one is available and appropriate for the patient's biology.

2. Breakthrough Targeted Cancer Therapies

Targeted therapy remains a cornerstone of modern oncology, particularly when paired with metabolic and immune strategies. Therapies aimed at tumors with KRAS mutations — once considered "undruggable" — are now showing genuine clinical impact in pancreatic and lung cancers, led by data from Revolution Medicines' RAS(ON) inhibitor program (see the pancreatic cancer section below for the headline 2026 result).

Key developments include:

  • Precision targeted drugs — new compounds inhibiting specific oncogenic pathways (KRAS, EGFR, BRAF) are entering trials or gaining regulatory attention.
  • Molecular profiling for therapy selection — ctDNA liquid biopsies let clinicians match patients to targeted agents and adjust therapy in real time.
  • Combination targeted approaches — blocking multiple signaling pathways simultaneously to delay resistance that limits single-agent therapies.

For patients with actionable mutations identified through molecular profiling, targeted options now commonly include PARP inhibitors for BRCA mutations, NTRK inhibitors, checkpoint inhibitors (pembrolizumab, dostarlimab) for MSI-H/dMMR tumors, KRAS G12C inhibitors, anti-HER2 agents, and BRAF/MEK inhibitors. Their long-term impact on survival still depends on addressing host metabolic and immune context — a theme central to OneDayMD's metabolic–immune framework.

3. AI-Driven Drug Discovery and Clinical Research

Artificial intelligence is now used across the research pipeline, from drug discovery to trial design, helping identify patterns in vast datasets more quickly and consistently than manual analysis allows. Platforms from companies such as 10x Genomics let researchers analyze tumors at single-cell resolution and within their spatial context, offering a more detailed view of how cancer and immune cells interact.

Randomized controlled trials remain costly and time-consuming. Incorporating computational simulation and AI into trial design could improve efficiency, optimize protocols, and reduce costs while improving the relevance of findings. In India, partners of the World Economic Forum are using AI-based risk profiling to help screen for common cancers like breast cancer and to analyze X-rays for cancer signs in settings where imaging specialists are scarce — two of 18 cancer interventions the Centre for the Fourth Industrial Revolution India is working to accelerate. AI-powered radiotherapy planning is following a similar trajectory, tailoring radiation dose to individual anatomy to reduce damage to healthy tissue.

4. Intra-Tumoral Chemotherapy's Revival

Intra-tumoral chemotherapy delivers anti-cancer drugs directly into a tumor rather than throughout the bloodstream. Instead of systemic exposure, doctors inject treatment precisely where it is needed, aiming to raise drug concentration inside the tumor, reduce systemic toxicity and side effects, and potentially stimulate an anti-tumor immune response by releasing tumor antigens locally.

The approach is gaining renewed interest because many tumors develop poor blood supply, hypoxic regions, dense stromal barriers, and resistance mechanisms that blunt intravenous chemotherapy. By bypassing some of these barriers, localized delivery may improve drug penetration — a way of managing the classic oncology trade-off in which enough drug to kill a tumor can also damage healthy tissue. It is being explored most actively in pancreatic cancer, liver tumors, melanoma, head and neck cancers, glioblastoma, and other accessible solid tumors, often in combination with immunotherapy, radiotherapy, nanoparticles, oncolytic viruses, or thermal ablation.

Several technologies are driving the revival: drug-eluting implants, gels, and microspheres that release chemotherapy over days or weeks; nanoparticle delivery systems designed to improve tumor penetration and selective targeting; and image-guided injection using ultrasound, CT, MRI, or endoscopic ultrasound for precise placement. Despite the momentum, intra-tumoral chemotherapy remains experimental in many cancers, technically challenging in tumors that are hard to access safely, and not a substitute for systemic therapy once microscopic metastases are already present. Large randomized trials are still needed to establish survival benefit, optimal drug combinations, and patient selection criteria.

5. Repurposed Drugs and Metabolic Therapy

A significant and socially visible trend in 2025–2026 has been the growing use of repurposed drugs — medications originally developed for non-cancer conditions that show promise in oncology. Genuine "breakthroughs" meaningfully change survival, remission rates, or quality of life, often through a new mechanism of action, a new way to select patients, or a less toxic approach; access to such therapies remains limited in low- and middle-income countries, where cancer survival still lags high-income settings due to funding and infrastructure gaps.5

Repurposing is well-established pharmaceutical practice: it leverages existing safety data instead of developing an entirely new compound from scratch, cutting both timelines and regulatory risk. Sildenafil (originally for hypertension) became Viagra; pembrolizumab, first approved for melanoma, is now used across lung, bladder, and head and neck cancers; semaglutide, developed for type 2 diabetes, found a second life in weight management. Oncology has its own version of this pattern.

Evidence Tier Key (Oxford CEBM Levels)

Tier 1–2Randomized trial / cohort evidence   Tier 3Case-control / limited controlled data   Tier 4–5Case series / mechanistic & expert opinion
  • Metformin Tier 3 — originally for type 2 diabetes; disrupts cancer cell metabolism and is under investigation as a complementary approach, including for enhancing immune response and potentially boosting vaccine efficacy in combination regimens.6
  • Anastrozole Tier 1–2 — an established breast cancer treatment now repurposed and approved in some settings for risk reduction, lowering estrogen levels to reduce breast cancer risk.
  • Ivermectin, mebendazole, and fenbendazole Tier 4–5 — antiparasitic agents studied for anticancer activity via microtubule disruption. A protocol led by researchers including Dr. Ilyes Baghli and Dr. Paul Marik outlines the proposed mechanism.7 More than 700 patient-reported case accounts on fenbendazole exist, but these are anecdotal, not controlled trial data, and should be weighed accordingly.

These repurposed drugs are particularly attractive in low- and middle-income countries, where access to expensive novel therapies is limited and an established safety profile can accelerate responsible clinical use. Still, controlled clinical trials are needed to confirm efficacy for the lower-tier agents, and patients considering these approaches should work with an integrative oncologist to tailor any protocol to their diagnosis and treatment plan rather than substituting it for guideline-based care.

6. Personalized Cancer Vaccines and Gene Therapy

Cancer vaccines have moved beyond prevention into personalized, tumor-specific treatment. mRNA-based vaccines are designed to train the immune system to recognize and attack an individual patient's cancer, offering a highly tailored approach. Thousands of NHS cancer patients in England may soon access trials of a vaccine designed to prime the immune system against cancer cells and reduce recurrence risk, with fewer side effects expected than conventional chemotherapy. Thirty hospitals have joined the Cancer Vaccine Launch Pad, matching patients to trials using the same mRNA platform behind current COVID-19 vaccines; more than 200 patients across the UK, Germany, Belgium, Spain, and Sweden are receiving up to 15 doses, with results expected by 2027.

Cancer Gene Therapy

Gendicine, a recombinant human p53 adenovirus developed by Shenzhen SiBiono GeneTech, was the first commercial gene therapy for cancer, approved in China in 2003 for head and neck cancer. It restores wild-type p53 tumor-suppressor function, prompting cell-cycle arrest, apoptosis, or senescence depending on cellular stress. By 2013, an estimated 30,000 patients had received Gendicine, with published data reporting a cumulative response rate above 90% and few serious adverse effects. Long-term follow-up across thirteen published studies indicates that Gendicine combination regimens extend progression-free survival compared with standard therapy alone, and outcomes did not depend heavily on each tumor's own p53 mutation status.8 Twenty years on, ongoing trials continue to test Gendicine across lung, liver, and cervical cancers.

CRISPR Gene Editing

CRISPR-based gene editing has progressed into clinical trials, allowing researchers to edit genes within cancer cells or immune cells to correct mutations that drive tumor growth or to sharpen immune-cell targeting.

7. Precision Medicine, Genomics & Chemo-Sparing Tests

Precision medicine tailors prevention and treatment to each person's genetic makeup, tumor biology, and lifestyle rather than applying a one-size-fits-all protocol. The UK's 100,000 Genomes Project studied more than 13,000 tumor samples from cancer patients, successfully integrating genomic data to more precisely match patients to effective treatment, and because precision oncology targets specific molecular drivers rather than dividing cells broadly, it generally means less harm to healthy tissue and fewer side effects than conventional chemotherapy.

ASCO 2026 Update: Genomic Testing Now Sparing Patients From Chemotherapy

The clearest 2026 example of precision diagnostics changing practice is the phase 3 OPTIMA trial, led by Professor Rob Stein (UCL) and Professor Iain MacPherson (University of Glasgow). Among 4,429 patients aged 40 and older with high-risk, estrogen receptor-positive, HER2-negative early breast cancer, those whose tumors scored low on Veracyte's Prosigna (PAM50) 50-gene Risk of Recurrence test did just as well on hormone therapy alone as they did on chemotherapy plus hormone therapy at five years.9 The investigators estimate the approach could help thousands of eligible patients avoid chemotherapy and its side effects every year, and a follow-on phase of OPTIMA is now examining whether younger, premenopausal women with this subtype could safely do the same.

A related plenary result, the phase 3 ASCENT-04 trial, found that combining the antibody-drug conjugate sacituzumab govitecan with pembrolizumab improved progression-free survival compared with standard therapy in previously untreated PD-L1-positive metastatic triple-negative breast cancer, supporting the combination as a potential new first-line standard for that subgroup.10

Liquid Biopsies for Early Detection

Work presented at AACR 2026 by CRI research scientist Fahad Benthani, PhD, showed how the clinical landscape is evolving: analyses of more than 24,000 global immunotherapy trials reveal increasing diversity in therapeutic approaches and combination strategies, along with shifting biomarker-driven development. Liquid biopsies — blood tests detecting cancer-related genetic mutations — are becoming more refined and accessible, enabling earlier detection, real-time monitoring, and more personalized treatment adjustments.

8. Pancreatic Cancer Breakthrough 2026

Pancreatic cancer is one of the deadliest common cancers, rarely diagnosed before it spreads, with a five-year survival rate historically below 5%. Two developments in 2026 are meaningfully changing that picture.

Daraxonrasib and the RASolute 302 Trial

RAS mutations drive the overwhelming majority of pancreatic ductal adenocarcinomas (PDAC) and were considered undruggable for decades. Daraxonrasib, Revolution Medicines' oral multi-selective RAS(ON) inhibitor, changed that calculus at ASCO 2026. In the phase 3 RASolute 302 trial, 500 patients with previously treated metastatic PDAC were randomized to daraxonrasib or investigator's choice of chemotherapy. Daraxonrasib produced a median overall survival of 13.2 months versus 6.7 months with chemotherapy (hazard ratio 0.40), with fewer serious adverse events and a generally manageable safety profile — a benefit that held regardless of the patient's specific RAS mutation subtype.11 Results were published simultaneously in the New England Journal of Medicine, and Revolution Medicines intends to submit the data to the FDA to support approval as a new second-line standard of care. A companion trial, RASolute 303, is now testing daraxonrasib with or without chemotherapy in the first-line setting.

Earlier Detection: Liquid Biopsy and PAC-MANN

At the University of California San Diego School of Medicine, scientists developed a test that identified 95% of early pancreatic cancers in a study published in Nature Communications Medicine, using biomarkers in extracellular vesicles to detect pancreatic, ovarian, and bladder cancer at stages I and II. A newer test, PAC-MANN, can flag signs of the disease from a single drop of blood. Separately, a US/UK study found that pancreatic cancer shuts down particular molecules in a key gene, a discovery Dr. Chris Macdonald of Pancreatic Cancer UK said could inform more effective future treatment options.

9. Gut Microbiome and Cancer Therapy

The gut microbiome's role in cancer treatment continues to draw research interest, with evidence that certain gut bacteria can enhance immunotherapy's effectiveness. Personalized probiotics and microbiome-targeted therapies are under active investigation as a way to potentially improve response rates to existing immune-based treatments.

AACR & ASCO 2026 Plenary Highlights

AACR 2026 Clinical Trials Plenary sessions covered:

ASCO 2026 Plenary Session (May 29–June 2, Chicago) delivered three results oncologists are calling practice-changing in a single meeting: daraxonrasib's survival benefit in pancreatic cancer (RASolute 302), the Prosigna test's ability to spare chemotherapy in breast cancer (OPTIMA), and ivonescimab's survival edge over standard immunotherapy in squamous lung cancer (HARMONi-6) — alongside adjuvant selpercatinib data in RET fusion-positive lung cancer (LIBRETTO-432) and perioperative apalutamide results in high-risk prostate cancer (PROTEUS).12 ASCO Breakthrough 2026, held in Singapore June 25–27, followed up with regional context on precision oncology, AI, and biomarker-driven care for Asia-Pacific clinicians and patients.

The Future of Cancer Treatment: Combination Strategies

Cancer is rarely defeated with a single intervention. Think of cancer therapy as a chessboard: no one wins with a single powerful move alone, but by coordinating multiple pieces toward a strategic advantage. Future oncology increasingly combines immunotherapy, targeted therapy, radioligand therapy, surgery, metabolic therapy, anti-angiogenic approaches, repurposed drugs, lifestyle interventions, and precision diagnostics. The likely destination is personalized, adaptive, multi-modal cancer care rather than a single universal treatment.

Important reality check: despite extraordinary progress, cancer remains complex, and many "breakthroughs" generate headlines long before proving a meaningful survival benefit in large human trials. Some therapies work spectacularly for small subsets of patients but not for most people; others improve progression-free survival without significantly extending overall survival. Careful interpretation of the evidence matters more than the headline.

Bottom Line

The landscape of cancer treatment in 2026 is marked by rapid innovation, from high-tech approaches like CRISPR, AI-driven discovery, and RAS(ON) inhibition to practical, cost-effective options like repurposed drugs and integrative approaches. The throughline from both AACR 2026 and ASCO 2026 is the same: cancer research is moving from isolated discoveries toward integration — connecting biology, technology, and policy to deliver real-world impact for a broad community of patients, researchers, and clinicians.

The most important cancer breakthroughs of 2025–2026 include the expansion of immunotherapy and bispecific antibodies, next-generation CAR-T and CAR-NK therapies, antibody-drug conjugates, radioligand therapy, AI-driven oncology, chemo-sparing genomic diagnostics, and earlier cancer detection. Rather than a single "cure for cancer," the field is moving toward increasingly personalized treatment strategies tailored to each patient's and each tumor's biology — a revolution built from many coordinated advances rather than one magic bullet. Staying informed, including about the promise and limits of repurposed drugs, can help patients and caregivers make better-informed treatment decisions in partnership with their care team.

Frequently Asked Questions

What is the biggest cancer treatment breakthrough in 2026?

There is no single breakthrough, but the phase 3 RASolute 302 trial stands out: daraxonrasib nearly doubled overall survival in previously treated metastatic pancreatic cancer compared with chemotherapy, and was published simultaneously in the New England Journal of Medicine. The OPTIMA trial (chemo-sparing genomic testing in breast cancer) and the HARMONi-6 trial (ivonescimab in lung cancer) were the other two headline ASCO 2026 results.

What is daraxonrasib and how does it work?

Daraxonrasib is an oral, multi-selective RAS(ON) inhibitor that blocks the active state of mutant and wild-type RAS proteins, including RAS G12, G13, and Q61 variants that drive most pancreatic cancers. In RASolute 302, it produced a median overall survival of about 13.2 months versus 6.7 months with chemotherapy.

Can a genomic test really help me avoid chemotherapy?

For a defined group, yes. The OPTIMA trial found that patients 40 and older with high-risk, ER-positive, HER2-negative early breast cancer and a low Prosigna (PAM50) Risk of Recurrence score did just as well on hormone therapy alone as with chemotherapy added. This is specific to that population; the decision should always be made with your oncologist based on your own test results.

Is CAR-T cell therapy safe, and does it cause secondary cancers?

CAR-T has produced remissions lasting well over a decade in some patients. After reviewing postmarketing reports, the FDA required a boxed warning on all approved CAR-T products for secondary T-cell malignancies (finalized 2024). Later systematic reviews suggest the absolute risk is low relative to the benefit, and prescribing patterns have not meaningfully changed, though lifelong monitoring is recommended.

What are repurposed drugs in cancer treatment, and how strong is the evidence?

Repurposed drugs are medications developed for other conditions — such as the antiparasitics ivermectin, mebendazole, and fenbendazole, or the diabetes drug metformin — that show anticancer activity. Evidence quality varies widely: some agents have supporting cohort or trial data in specific contexts, while others rest mainly on mechanistic research and patient-reported case series rather than randomized trials. Discuss any repurposed-drug approach with an integrative or treating oncologist rather than substituting it for standard care.

What is the difference between immunotherapy and chemotherapy?

Chemotherapy kills rapidly dividing cells throughout the body, causing broad side effects. Immunotherapy trains or unleashes the patient's own immune system to target cancer specifically, often with a different side-effect profile. Many cancers now use immunotherapy or targeted therapy first, reserving chemotherapy for specific situations.

Are personalized mRNA cancer vaccines available yet?

Mostly through clinical trials rather than as an approved standard treatment. Programs like the UK's Cancer Vaccine Launch Pad are matching patients to mRNA-based vaccine trials aimed at reducing recurrence risk, with results from several studies expected by 2027.

How reliable are early "cancer breakthrough" headlines?

Treat them cautiously. Many promising results come from small, early-phase, or single-arm studies not yet confirmed in large randomized trials, and a progression-free survival benefit doesn't always translate into an overall survival benefit. Look for phase 3, randomized, peer-reviewed data with an overall survival endpoint before treating a result as practice-changing.

Using AI to Personalize This Guide

This guide covers general trends across many cancer types. To connect it to a specific diagnosis, pathology report, or treatment decision, you can paste the relevant section into an AI assistant along with your own details (with personal identifiers removed) and ask it to translate the research into plain language for your situation. A few starting prompts:

  • Claude / ChatGPT: "Here is my pathology report summary and this article's pancreatic cancer section — explain in plain language whether daraxonrasib-type RAS(ON) inhibitors would be relevant to discuss with my oncologist."
  • Gemini: "Compare the evidence tiers for metformin versus fenbendazole in this article and summarize what a treating oncologist would likely want to see before recommending either."
  • Perplexity: "Find the most recent published follow-up data on the OPTIMA trial and the Prosigna test since July 2026."

AI assistants can help you understand terminology and organize questions for your care team, but they cannot replace an oncologist's review of your specific pathology, imaging, and treatment history.
