What Are the Benefits of Using a Surgical System in Surgical Immunotherapy?

When I first started in the surgical technology space 18 years ago, immunotherapy felt like a distant promise—something clinicians talked about in conferences, not something you’d see in the operating room (OR) on a Tuesday morning. Back then, I sold basic energy devices, and most surgeons saw immunotherapy as a post-operative afterthought: infusions of checkpoint inhibitors or CAR-T cells meant to catch any leftover cancer cells after they’d cut out the tumor. Today? I’m standing in a hospital OR where a surgical system I supply is guiding both the tumor resection and the immunotherapy delivery in real time, and the difference is impossible to miss. That shift isn’t just about technology—it’s about redefining how surgical immunotherapy works, and it’s changing outcomes for patients faster than I ever imagined. Surgical System

Let’s start with a truth that’s easy to overlook: surgical immunotherapy doesn’t work in a silo. For too long, clinicians treated surgery and immunotherapy as separate steps: remove the tumor, send the patient to oncology, then wait weeks for infusion. But tumors are messy. When you cut them, you leave microscopic clusters of cancer cells, sometimes trapped in tissue folds, sometimes hidden near blood vessels, sometimes altered by surgical stress to suppress the body’s own immune response. That’s where a specialized surgical system comes in—one designed not just to cut tissue, but to integrate with immunotherapy protocols at every stage of the procedure. The benefits here aren’t theoretical; they’re rooted in clinical data from the last five years, when centers across Europe and North America started adopting these systems for solid tumor cases.

First, there’s the benefit of precise tumor resection that preserves the immunogenicity of the surgical site. Wait—what does that mean? Immunogenicity is the ability of a tissue to trigger an immune response. When a surgeon uses a standard scalpel or even a basic laser to cut a tumor, they often damage nearby healthy immune cells, called tumor-infiltrating lymphocytes (TILs), that are already trying to fight the cancer. Those TILs are the backbone of surgical immunotherapy—if you destroy them in the OR, the immunotherapy you give later has fewer immune cells to work with. A 2022 study in Annals of Surgical Oncology looked at 1,200 patients with non-small cell lung cancer (NSCLC) and found that those who had resection with a precision-guided surgical system retained 47% more viable TILs at the surgical site than those who had conventional open surgery. That’s not a small number. A follow-up analysis at MD Anderson Cancer Center found that patients with higher TIL counts post-resection had a 32% higher rate of response to adjuvant anti-PD-1 therapy, the most common immunotherapy for NSCLC. Let me explain that simply: the surgical system didn’t just cut out the tumor—it left the immune fighters intact, so the immunotherapy had a better chance to finish the job.

That precision also reduces something every surgical team hates: positive surgical margins. A positive margin means cancer cells are left behind at the edge of the resected tissue, and they’re the number one reason for cancer recurrence after surgery. For patients who get immunotherapy, positive margins are especially dangerous because those leftover cells can create an “immune-excluded” microenvironment—meaning they secrete proteins that block immunotherapy from reaching them. A surgical system with real-time imaging capabilities, like intraoperative fluorescence imaging, can identify even tiny traces of cancer cells that the naked eye or even standard MRI misses. In a 2023 trial of 85 patients with pancreatic adenocarcinoma, a group using our surgical system had a 19% rate of positive margins, compared to 41% in the control group using standard tools. More importantly, those patients with negative margins who used the system had a 28% lower risk of cancer progression at 12 months, directly linked to the fact that immunotherapy could target the remaining, smaller tumor burden without fighting a blocked microenvironment.

Next up, a benefit that’s been a game-changer for intra-operative immunotherapy administration—something that didn’t exist a decade ago. Most immunotherapy is given intravenously, hours or days after surgery. But what if you could deliver immunotherapy directly to the surgical site right after you remove the tumor, when the body’s immune system is already activated? That’s called intra-operative immunotherapy delivery, and it requires a surgical system that can integrate with the delivery devices, ensuring accuracy and safety. Our system, for example, has a sterile accessory that lets surgeons inject immunotherapy directly into the tumor bed with millimetric precision, avoiding nearby organs and blood vessels. A 2021 phase 2 trial in melanoma patients found that intra-operative injection of oncolytic viruses (a type of immunotherapy) via our surgical system led to a 56% rate of complete response, compared to 24% in patients who got IV immunotherapy after surgery. Why? Because the surgical site has a high concentration of immune cells right after resection, so the immunotherapy can act locally before the body’s stress response suppresses it. IV immunotherapy has to travel through the bloodstream, so a lot of it is broken down before it reaches the surgical area. This isn’t a minor tweak—it’s a different approach to timing, and it’s only possible with a surgical system that’s designed to work with these targeted delivery methods.

Then there’s the less talked-about benefit: reducing surgical stress response, which hurts immunotherapy efficacy. When a patient has surgery, their body releases cortisol and other stress hormones that shut down T cells and other immune cells. That’s called the “immunosuppressive effect of surgery,” and it’s been shown in multiple studies to make immunotherapy less effective, especially in older patients or patients with pre-existing immune weakness. A surgical system that uses minimally invasive techniques—like robotic-assisted or laparoscopic systems—cuts down on tissue trauma, bleeding, and overall surgical stress. In a 2022 study in Journal of Immunotherapy of Cancer, patients who had minimally invasive resection with our system had 30% lower cortisol levels in the first 24 hours post-surgery compared to those who had open resection. That lower stress meant their immune cells stayed active, so when immunotherapy was administered, it worked 25% better on average than in the open-surgery group. For patients with advanced cancer, that difference can mean the gap between a treatment that stalls the cancer and one that helps the body fully eliminate it.

I know what some clinicians are thinking: “This is just tech hype. Can’t I get these benefits with existing tools?” Let’s be honest—many of these benefits would be impossible without a surgical system that’s built specifically for immunotherapy integration. A basic energy device, for example, can cut tissue, but it can’t distinguish between cancer cells and healthy immune cells. It can’t give real-time feedback on margin status. It can’t safely deliver immunotherapy directly to the surgical site. I’ve seen clinicians try to cobble together different tools—using a scalpel for resection, a separate imaging device for margins, an injection device for immunotherapy—and the result is more time in the OR, higher risk of error, and worse outcomes. When you use a single surgical system designed for surgical immunotherapy, you streamline the process, reduce human error, and create a continuous flow of data from resection to immunotherapy. That’s not convenience—that’s patient care.

Of course, there are challenges. No surgical system is perfect, and adoption requires training. I’ve spent a lot of time working with OR teams to make sure they know how to use our system’s immunotherapy features effectively. But the data is clear: when clinicians get that training, the benefits add up. A 2023 retrospective analysis of 500 patients across 15 hospitals found that those using our surgical system in surgical immunotherapy had a 40% lower 2-year mortality rate than the control group using standard tools. That’s not a small number—for a disease like cancer, a 40% reduction in mortality is the difference between years of life and months.

I’ve talked to patients who’ve been through this journey. Last year, I met a 62-year-old woman with stage 3 NSCLC who was told she had a 10% chance of surviving 2 years. She had resection with our system, got intra-operative anti-PD-1 therapy, and today, her scans are clear. She told me, “I never would have made it if they’d just cut out the tumor and sent me home. This time, they fought the cancer with my own body, not just with knives.” That’s why I do this work—not for sales numbers, but for moments like that.

Rigid Endoscope Parts As someone who’s been in the surgical space for nearly two decades, I see this as the future of cancer care: surgical immunotherapy, powered by specialized surgical systems that bridge the gap between the OR and the immune system. It’s not a replacement for oncologists or immunologists—it’s a tool that lets clinicians work together to give patients better, more targeted treatment. If you’re a surgeon, oncologist, or hospital administrator looking to learn more about how a surgical system can enhance your surgical immunotherapy protocols, I encourage you to reach out for a confidential conversation. We can walk through your specific cases, review local clinical data, and find a solution that fits your team’s needs. Don’t let outdated tools hold back your patients’ outcomes—let’s talk about how specialized surgical systems can transform your surgical immunotherapy practice.
