AI tools for oncology: precision oncology, biomarker matching, and CDS

May 6, 2026 · Pouyan Golshani, MD, Interventional Radiologist

Oncology AI is dense and moving fast. Here’s the directory of tools with real deployment data. The pace of change in precision medicine, driven by AI-powered biomarker analysis and clinical trial matching, is staggering. For practicing oncologists, this isn’t just an academic curiosity; it’s a fundamental shift in our clinical workflow and decision-making. Keeping up requires a dedicated effort, but the payoff in patient outcomes is undeniable. These tools are no longer theoretical—they are being deployed in major cancer centers and integrated into EMRs, directly impacting how we select therapies and manage complex cases. This article serves as a practical directory of the major categories of AI tools in oncology and, just as importantly, the financial and operational strategies required to build a sustainable career around this evolving standard of care. For a broader look at the landscape, the full collection of oncology AI tools and resources provides continuously updated information.

AI in Practice: From Biomarker Matching to Clinical Decision Support

The application of AI in oncology generally falls into three major buckets: precision oncology, operational efficiency, and clinical decision support (CDS). Each has matured significantly, with validated tools now available for clinical use.

Precision Oncology & Biomarker Matching: This is the most mature application. Genomic and proteomic data from patient tumors create a massive dataset that is impossible for a human to manually cross-reference against all available clinical trials and off-label therapies. AI platforms ingest this data (e.g., NGS reports) and match a patient’s specific molecular profile to targeted therapies or trial enrollment criteria. Tools from companies like Tempus and Foundation Medicine have become standard, but a new wave of software aims to integrate this matching process directly into the EMR, flagging potential options in real time. The core function is to reduce the time from molecular diagnosis to effective treatment selection, a critical factor in aggressive cancers.

Operational Efficiency: This category focuses on the non-clinical tasks that consume a significant portion of an oncologist’s day. AI-powered scribes can listen to a patient encounter and generate a structured clinical note, cutting documentation time. Other tools help streamline prior authorization workflows by auto-populating forms and tracking submissions. While less glamorous, these operational tools can have a significant impact on physician burnout and practice throughput, allowing more time for direct patient care and complex decision-making.

Clinical Decision Support (CDS): This is the forward-looking edge. CDS tools integrate directly into the clinical workflow to provide real-time guidance. This can range from flagging potential drug-drug interactions with complex chemotherapy regimens to suggesting imaging follow-up based on guideline criteria (e.g., NCCN). Developer-facing tools like the Pogosh CDS API are designed to allow health systems to build their own custom clinical logic and alerts directly into their existing EMR, rather than relying on a one-size-fits-all solution. The goal is to embed evidence-based medicine directly at the point of care. You can explore a curated list of platforms in the physician AI tools directory.

The Oncologist’s Edge: Actually Qualifying for the 20% QBI Deduction

While we integrate these advanced clinical tools, we can’t neglect the financial tools that sustain our careers. One of the most powerful—and misunderstood—is the Section 199A Qualified Business Income (QBI) deduction. For many high-earning specialists, this 20% deduction on pass-through income is a non-starter because their income exceeds the phase-out threshold for a “Specified Service Trade or Business” (SSTB), which includes the practice of medicine.

However, for many W-2 employed oncologists, whose compensation is often in a range that makes this achievable, the QBI deduction is very much in play. For 2026, the income phase-out threshold is projected to be around $394,000 for single filers and $787,000 for those married filing jointly. If your taxable income is below this, you can get the full 20% deduction on qualified business income. The key is that this threshold is based on your taxable income, not your gross income.

Here’s the strategy: actively manage your Adjusted Gross Income (AGI) down to stay under the threshold.

Max Out Pre-Tax Retirement Accounts: This is the first and easiest step. Contribute the maximum to your employer-sponsored 401(k) or 403(b).
Utilize an HSA: If you have a high-deductible health plan, max out your Health Savings Account ($8,750 for a family in 2026). This is an above-the-line deduction that directly lowers your AGI.
Charitable Bunching: If you make regular charitable donations, consider “bunching” two or three years’ worth of contributions into a single year using a Donor-Advised Fund (DAF). This can create a large enough deduction to push your AGI below the phase-out limit in a given year.

The trap to avoid is assuming you earn too much to qualify without running the numbers. An oncologist with a $450,000 salary might think they’re out of luck. But after maxing a 401(k), an HSA, and making a significant charitable contribution, their taxable income could easily fall below the threshold, preserving a deduction worth tens of thousands of dollars on any side-gig 1099 income.

Rescuing Lost Deductions: The W-2 Employee’s Schedule C Workaround

The Tax Cuts and Jobs Act of 2017 (TCJA) was a major blow to W-2 physicians. It eliminated the miscellaneous itemized deduction for unreimbursed employee expenses. This meant we could no longer deduct essential costs of our profession: CME courses, conference travel, medical license renewals, DEA fees, board certification fees, scrubs, or home office equipment. For many oncologists, these expenses add up to thousands of dollars a year that are now paid with post-tax money.

The fix is to generate even a small amount of 1099 independent contractor income. This income is reported on a Schedule C, “Profit or Loss from Business.” The moment you have a Schedule C, you have a place to deduct all “ordinary and necessary” business expenses against that 1099 income. The same expenses that were non-deductible as a W-2 employee become fully deductible as a business owner.

Here’s the how-to sequence:

Establish a Side Gig: This can be anything from telemedicine shifts, expert witness reviews, consulting for a biotech startup, or medical directorship for a local hospice.
Receive 1099-NEC Income: The entity that pays you will issue a Form 1099-NEC for this work.
File a Schedule C: With your tax return, you’ll file a Schedule C. You report your 1099 income as revenue. Then, you deduct your professional expenses—CME, licenses, DEA, home office, a portion of your cell phone and internet, etc.—against that revenue.

Let’s say you earn $10,000 from consulting but have $8,000 in legitimate professional expenses. As a W-2 employee, you’d pay tax on your full salary and eat the $8,000 cost. With the Schedule C, you deduct the $8,000 from the $10,000, and you are only taxed on the $2,000 of net profit. You’ve effectively “rescued” $8,000 worth of deductions. The planning trap is thinking you need a massive side business. Even a few thousand dollars of 1099 income is enough to open up the Schedule C and make these critical professional expenses deductible again.

The Ultimate Long-Term Shelter: Triple-Stacking Your Health Savings Account

For physicians with a high-deductible health plan (HDHP), the Health Savings Account (HSA) is the single most powerful investment vehicle available—even better than a 401(k) or Roth IRA. It offers a unique triple tax advantage:

Tax-Deductible Contributions: The money you put in is deducted from your income, lowering your current tax bill. For 2026, the family contribution limit is $8,750.
Tax-Free Growth: The money inside the HSA can be invested in stocks and bonds, and it grows completely tax-free.
Tax-Free Withdrawals: You can withdraw the money tax-free at any time to pay for qualified medical expenses.

Most people use their HSA like a checking account for medical bills. This is a massive missed opportunity. The “HSA stacking” strategy turns it into a supercharged retirement account. Here’s how it works:

Step 1: Max It Out. Contribute the maximum family amount ($8,750 in 2026) every single year.

Step 2: Invest It. Do not leave the funds in cash. As soon as the money hits the account, invest it in a low-cost, diversified index fund portfolio, just like you would with your 401(k).

Step 3: Don’t Spend It. Pay for all your current medical expenses out-of-pocket with post-tax dollars. This is the crucial step.

Step 4: Save Your Receipts. Keep a digital record (a folder on your cloud drive is fine) of every single qualified medical expense you pay out-of-pocket. This includes co-pays, prescriptions, dental work, eyeglasses—everything.

Decades from now, in retirement, you will have a massive, tax-free investment account. You can then “reimburse” yourself for all those medical expenses you paid for over the years by taking tax-free distributions from the HSA. If you accumulated $200,000 in receipts over 30 years, you can pull $200,000 out of your HSA completely tax-free. After age 65, any withdrawals not matched to receipts are treated like a traditional IRA—taxable as income, but with no penalty. It’s a can’t-lose vehicle for long-term savings.
