Can HALP (Hemoglobin, Albumin, Lymphocytes, and Platelets) Score Differentiate Between Malignant and Benign Causes of Acute Mechanic Intestinal Obstruction?

Background: Hematological parameters, including albumin and hemoglobin (Hb) levels and lymphocyte counts, are low-cost tests that can be used to determine inflammation and nutritional status. Recent studies have shown that inflammation plays a very important role in the development of carcinogenesis. Materials and Methods: The authors investigated whether preoperative hemoglobin, albumin, lymphocyte, and platelet (HALP) score can distinguish between benign and malignant causes in patients who are admitted to hospital and operated due to acute mechanical intestinal obstruction (AMIO). The patients were divided into two groups etiologically. Group 1 included the AMIO cases, which developed from benign causes, while Group II contained the AMIO cases, which developed as a result of malignancy. HALP score was calculated based on the latest preoperative Hb, albumin, lymphocyte, and platelet values of patients. Results: HALP variable was an independent prognostic factor (p < 0.001) in determining malignancy (odds ratio = 0.91; 95% confidence interval [CI] = 0.882-0.930). Based on the results, when a cutoff value <23.94 was used for HALP score in receiver operating characteristic analysis, sensitivity for determining the malignancy was 85%, while specificity was 78% (Area under the curve [AUC] ± standard error = 0.86 ± 0.029; 95% CI = 0.80-0.91; p < 0.001). Conclusions: The HALP score could be a useful parameter for the clinician in distinguishing between AMIO due to benign and malignant origins.
