Introduction: Malnutrition is a common yet frequently underdiagnosed complication in cancer patients and is strongly associated with poor prognosis. Early identification through accurate screening and comprehensive nutritional assessment is essential for improving nutritional status and quality of life. Objective: The objective of this study was to evaluate the nutritional status of adult cancer patients using the Patient-Generated Subjective Global Assessment (PG-SGA) in combination with anthropometric, biochemical, and dietary parameters. Methods: This cross-sectional study assessed the nutritional status of 279 adult cancer outpatients using the PG-SGA, supplemented by medical and dietary histories, physical examinations, anthropometric measurements, and laboratory parameters. Results: According to PG-SGA scores, 31.3% of men and 12.6% of women were classified as severely malnourished. Anthropometric values showed a significant decline across PG-SGA categories, from well-nourished (PG-SGA-A) to severely malnourished (PG-SGA-C) patients (p<0.05). Serum albumin, total protein, hemoglobin, and total cholesterol levels were significantly higher in PG-SGA-A patients, whereas C-reactive protein was elevated in PG-SGA-C patients (p<0.05). Analysis of nutrient intake revealed higher consumption of fiber, fat, saturated fat, and cholesterol among PG-SGA-A patients compared with PG-SGA-C patients (p<0.05). thickness, mid-upper arm muscle area, mid-upper arm muscle circumference, and lean body mass were all negatively correlated with malnutrition severity (p<0.05). Conclusion: These findings confirm the high prevalence of malnutrition in oncology outpatients and underscore the importance of integrating both subjective and objective tools for early detection and timely management of malnutrition in cancer care.
