Pancreatic cancer and its treatment can make it difficult for patients to maintain weight, muscle, and adequate nutrition. The disease may interfere with digestion and nutrient absorption, while chemotherapy can cause nausea, diarrhea, fatigue, appetite loss, and other side effects. These challenges can contribute to malnutrition, treatment interruptions, and a more difficult recovery after surgery.
A new study published in Surgical Oncology Insight examined whether providing nutritional support early—beginning at the time of surgical consultation—could help patients better tolerate chemotherapy and recover from pancreatic cancer surgery.
What Did the Researchers Study?
Researchers at the University of Vermont Medical Center followed 18 patients with pancreatic cancer who participated in a nutritional prehabilitation program between 2023 and 2025. All ultimately underwent surgery.
Each patient met with a dietitian at the time of surgical consultation and received a detailed assessment of weight, muscle and fat loss, food intake, symptoms, and nutritional needs.
Patients then received individualized support that could include:
Strategies to increase calories and protein
Guidance on managing treatment-related digestive symptoms
Education about pancreatic enzyme dosing
Support for dumping syndrome
Vitamin and mineral supplementation
Feeding-tube support when necessary
Continued nutrition monitoring before and after surgery
The patients met with a dietitian an average of 21 times over approximately 10 months. Their outcomes were compared with those of 33 patients treated at the same institution between 2012 and 2022, before the nutritional prehabilitation program was introduced.
What Did the Study Find?
Nutritional concerns were common from the beginning. Thirteen of the 18 patients—72%—were malnourished enough to require dietitian intervention at their first assessment. Ten patients had moderate or severe symptoms related to malnutrition, and three required supplemental nutrition through a jejunostomy feeding tube.
Patients who received nutritional prehabilitation were able to complete substantially more of their prescribed chemotherapy. The average relative dose intensity—the percentage of the planned chemotherapy dose that a patient actually received—was:
81.9% among patients receiving nutritional prehabilitation
50.4% among patients receiving usual care
This difference was statistically significant. When researchers looked specifically at patients who received chemotherapy before surgery, the median relative dose intensity was 97% in the nutritional prehabilitation group compared with 43% in the historical comparison group.
Patients in the nutritional program were also less likely to require chemotherapy dose reductions. Approximately 56% required at least one reduction, compared with nearly 88% of patients in the earlier group.
Shorter Hospital Stays and Fewer Infections
Patients who received nutritional prehabilitation had a median hospital stay of six days following surgery, compared with nine days in the historical group.
Postoperative infections were also less common:
11.1% in the nutritional prehabilitation group
42.4% in the historical comparison group
Rates of gastrointestinal and other serious complications were lower in the nutritional group as well, but those differences were not statistically significant. This means the study could not establish with confidence that nutrition support was responsible for those particular differences.
Why Does This Matter?
Nutrition is sometimes treated as an added service rather than a central part of cancer care. However, this study found that nearly three out of four patients needed nutritional intervention when first evaluated.
The findings suggest that introducing a dietitian early—and keeping that professional involved throughout chemotherapy, surgery, and recovery—may help patients receive more of their planned treatment, spend less time in the hospital, and experience fewer postoperative infections.
For patients, nutritional prehabilitation is not simply about gaining weight or being told what to eat. It may include identifying pancreatic enzyme insufficiency, addressing nausea or diarrhea, managing blood sugar, protecting muscle mass, treating vitamin deficiencies, and finding realistic ways to meet nutritional needs during treatment.
Important Study Limitations
These results are encouraging, but the study was small and conducted at a single medical center. The researchers compared 18 patients in a current nutrition program with 33 patients treated during an earlier period rather than randomly assigning patients to different forms of care.
Other changes in chemotherapy, surgical care, infection prevention, and supportive services over time may have influenced the results. The earlier group also had a higher rate of preexisting gastrointestinal conditions, and their baseline nutritional status could not be reliably assessed.
Because of these limitations, the study shows an association but does not prove that nutritional prehabilitation alone caused the improved outcomes. Larger, multicenter studies are needed to determine whether these benefits can be reproduced and whether they improve long-term survival or reduce the overall cost of care.
What Patients Can Take Away
Patients preparing for pancreatic cancer treatment may benefit from requesting a nutritional assessment as early as possible—ideally before significant weight or muscle loss develops.
A registered dietitian experienced in pancreatic cancer can work with the oncology and surgical teams to address symptoms, pancreatic enzyme needs, food intake, and other factors that may affect treatment tolerance.
Patients and caregivers may want to ask:
Can I meet with an oncology dietitian before beginning treatment?
Have I been screened for malnutrition or muscle loss?
Could pancreatic enzyme insufficiency be affecting my digestion?
What symptoms or weight changes should I report?
How can nutrition support continue during chemotherapy and after surgery?
This study adds to growing evidence that nutrition should be integrated into pancreatic cancer care from the beginning—not introduced only after a patient has already experienced substantial weight loss or difficulty completing treatment.
