For patients with advanced head and neck cancer, the race against time does not end when a tumor is removed. In many cases, surgery must be followed by radiation therapy to eliminate microscopic cancer cells that remain in the surgical area. Clinical guidelines recommend beginning radiation within six weeks after surgery, a window known as timely adjuvant therapy. Yet nationwide, more than half of eligible patients fail to start treatment within that period. A new study from MUSC Hollings Cancer Center identifies the specific steps that determine whether patients reach radiation therapy on time—and suggests that one early appointment may influence the entire treatment pathway.
The study analyzed the mechanisms behind NDURE, short for Navigation for Disparities and Untimely Radiation Therapy. The program was designed to coordinate the complex sequence of appointments, referrals and treatment decisions that follows major head and neck surgery. Unlike conventional navigation, which may respond to problems after they occur, NDURE anticipates the next clinical requirement and actively helps patients and care teams complete it before delays develop. In an earlier randomized clinical trial, nearly three-quarters of patients receiving enhanced navigation began radiation on time, compared with approximately 40 percent of those receiving standard navigation.
The new analysis, led by head and neck surgical oncologist Evan Graboyes, focused on why the intervention worked. Researchers divided the period between surgery and radiation into five measurable milestones. These included meeting a radiation oncologist before surgery, completing a dental evaluation before the operation, seeing a radiation oncologist within 21 days after surgery, undergoing radiation-planning scans promptly and beginning radiation within 14 days of those scans. Each step represents a potential point of failure in a care pathway that may involve multiple departments, hospitals and health systems.
Patients enrolled in the enhanced navigation program were significantly more likely to complete the milestones than those receiving usual care. The relationship between milestone completion and treatment timing was especially strong. Ninety percent of patients who completed four or five of the care steps began radiation within six weeks, compared with only 10 percent of patients who completed one or none. The pattern suggests that timely cancer care is not determined by a single appointment or physician decision, but by the successful coordination of a tightly connected clinical process.
One milestone had an especially large effect: the postoperative visit with a radiation oncologist within three weeks of surgery. This appointment accounted for nearly one-quarter of the overall benefit associated with the enhanced navigation program. On average, NDURE reduced the time to that visit by about five days. Investigators describe the appointment as a potential “gateway” in the treatment pathway because it brings the radiation oncology team into the patient’s care early enough to organize the remaining steps.
The technical importance of that timing is substantial. Radiation therapy requires treatment planning, which may include imaging, computer-based mapping of the surgical bed and surrounding tissues, dose calculations and decisions about how to protect healthy organs. Dental evaluation can also be essential because radiation involving the jaw and oral cavity may increase the risk of tissue injury or complications involving teeth and bone. If the radiation oncologist is not involved soon after surgery, these preparations may be compressed into the final days of the six-week window, leaving little room for scheduling problems, wound recovery, transportation barriers or communication failures.
Head and neck cancer care is particularly vulnerable to such breakdowns because it relies on a “team of teams.” Surgeons, radiation and medical oncologists, dentists, nurses, rehabilitation specialists and patient navigators must coordinate while the patient is recovering from a major operation. At MUSC Hollings, the challenge can be amplified when patients travel to Charleston for specialized surgery and then return to local communities for radiation. Information and responsibility may pass between institutions, making it harder to maintain a shared timeline.
The findings do not mean that every cancer center must adopt NDURE in its exact form. Instead, they offer practical performance targets that health systems can pursue through different methods, including electronic reminders, rapid referral pathways, dedicated scheduling staff, cross-institution communication protocols or patient navigation. The central lesson is that care coordination can be evaluated scientifically: researchers can track whether patients complete defined milestones and determine which steps contribute most to timely treatment. This approach moves cancer delivery research beyond the simple question of whether an intervention works and toward understanding its mechanism.
For patients, starting radiation within six weeks can affect the likelihood that treatment controls the disease and reduces the risk of recurrence. For health systems, the study provides a measurable roadmap for improving the transition from surgery to adjuvant therapy. The NDURE program is now being tested in a National Cancer Institute-funded multicenter trial involving MUSC, Baylor University, Duke University and Washington University in St. Louis. If the approach improves treatment timing across different hospitals and patient populations, it could offer a scalable model for closing one of the most persistent gaps in head and neck cancer care: ensuring that a medically recommended treatment is delivered not only correctly, but on schedule.
