👥Biography 个人简介
Digant Gupta is a cancer outcomes researcher who has extensively studied the prognostic value of nutritional status in oncology. His work validated the Prognostic Nutritional Index and other nutrition-based prognostic scores across cancer types, demonstrating that nutritional assessment provides independent prognostic information beyond tumor staging.
🧪Research Fields 研究领域
🎓Key Contributions 主要贡献
Prognostic Nutritional Index Validation
Systematically validated the Prognostic Nutritional Index (PNI) in large oncology cohorts across multiple tumor types, establishing serum albumin and lymphocyte count as independent prognostic biomarkers.
Malnutrition and Cancer Outcomes
Conducted large observational studies demonstrating associations between pre-treatment malnutrition, nutritional decline during treatment, and survival, hospital resource utilization, and quality of life in cancer patients.
Nutrition Screening Implementation
Investigated patterns of nutritional screening adoption in US cancer centers and barriers to implementation, contributing to quality improvement frameworks for oncology nutritional care.
Representative Works 代表性著作
The relationship between nutritional status and quality of life in cancer
Support Care Cancer (2011)
Large cross-sectional study demonstrating that nutritional status assessed by the PG-SGA strongly correlates with quality of life in cancer patients, supporting nutrition as a quality-of-care indicator.
Malnutrition was associated with poor quality of life in colorectal cancer
Journal of Clinical Epidemiology (2006)
Seminal study linking nutritional depletion to diminished quality of life in colorectal cancer, helping justify investment in nutrition support programs in oncology.
Prognostic nutritional index as a predictor of survival in patients with lung cancer
Clinical Nutrition (2014)
Prospective validation of the Prognostic Nutritional Index in lung cancer, showing PNI adds independent prognostic value beyond standard tumor-node-metastasis staging.
