Abstract
BACKGROUND/OBJECTIVE: In this study, we aimed to determine the relationship between HALP score and postoperative complications (According to Clavien-Dindo classification 3 and above), in patients with colo-rectal cancer who underwent curative surgical resection and to determine its clinical value in predicting prognosis.
METHODS: 279 patients who underwent curative surgery for colorectal cancer between 2015-2018 were included in the study. The HALP value was calculated by dividing the product of hemoglobin (g/L), albumin (g/L), lymphocytes (/ L) by the number of platelets (/ L). In order to generate a cut off value for the HALP value, ROC analysis and ROC curve were created. The patients were divided into two groups according to survival, and cut off value was found by ROC analysis: Group 1 (Low HALP) and Group 2 (High HALP). Demographic, clinical characteristics, intraoperative , postoperative results and mean survival were compared between the groups.
RESULTS: The patients were divided into two groups according to cut off value of 15.73. Group 1 consisted of 113 patients; Group 2 consisted of 166 patients. Average age was similar in the groups (62vs61, p:0.480). Patients in Group 1 received more neoadjuvant therapy (31%vs21%, p:0.064). CEA levels were higher in Group 1 (7.6vs4.3 p:0.034). Mucinous adenocarcinoma histological type was more common in Group 1 (24%vs13% ,p:0.040). Pathological grade poorly differentiated was more common in Group 1 (27%vs13%). Postoperative outcomes was similar to groups We found the HALP score as a risk factor for survival in multivariate analysis (HR=0.8552 95% (CI:0.6575-1.1125, p:0.007). If the HALP value is below 15.73, it is assumed that the average survival is 28 months with 45.4% sensitivity and 66.938% specificity.
CONCLUSION: Our results showed that the HALP score is closely related to clinic pathological features and is an independent prognostic factor for survival. Its value in estimating mean survival is limited.
