Malnutrition impacts head and neck cancer (HNC) outcomes. The geriatric nutritional risk index (GNRI) predicts worse survival and treatment intolerance in operable HNC patients.
Area of Science:
- Oncology
- Geriatrics
- Surgical Oncology
Background:
- Malnutrition is a known predictor of adverse outcomes in head and neck cancer (HNC) patients.
- The Geriatric Nutritional Risk Index (GNRI) is a potential tool for assessing nutritional status and predicting outcomes, but its specific role in HNC requires further investigation.
Purpose of the Study:
- To evaluate the predictive value of the preoperative Geriatric Nutritional Risk Index (GNRI) for postoperative morbidity, mortality, and survival in patients undergoing surgery for head and neck cancer (HNC).
Main Methods:
- An ambispective study included 312 treatment-naïve patients undergoing HNC surgery across two academic centers from 2015 to 2024.
- Preoperative GNRI scores were categorized into moderate-to-high risk (<92), low risk (92-98), and no risk (>98).
- Outcomes assessed included 90-day mortality, treatment intolerance, overall survival, and disease-free survival, with analyses adjusted for relevant clinical and demographic factors.
Main Results:
- Patients with moderate-to-high GNRI risk (13%) experienced higher rates of major adverse events (57% vs. 36%) and treatment intolerance (61% vs. 41%) compared to those with no risk.
- Multivariable analysis revealed that moderate-to-high GNRI risk was significantly associated with increased odds of 90-day mortality (OR 2.99) and treatment intolerance (OR 2.35).
- Cox regression demonstrated that a lower GNRI score predicted significantly shorter overall survival (HR 2.28) and disease-free survival (HR 1.87).
Conclusions:
- The preoperative Geriatric Nutritional Risk Index (GNRI) is a valuable tool for predicting treatment intolerance and poorer survival outcomes in patients with operable head and neck cancer (HNC).
- Incorporating GNRI assessment into preoperative evaluations may aid in identifying high-risk HNC patients who could benefit from targeted nutritional interventions.
