  • Estimation of Operation Risk in Lung Cancer Patients Undergoing Surgery Using POSSUM

    Abstract : Objective To evaluate the clinical validity of Physiological and Operative Severity Score for theenUmeration of Mortality and Morbidity (POSSUM) in primary lung cancer patients undergoing surgery in order to get clinical treatment reference. Methods A total of 179 patients,with 124 males and 55 females,with primary lung cancer surgery between January 2007 and October 2010 were included in the First Affiliated Hospital of Xinjiang Medical University. Their age was 59.2±11.4 years.Before the surgery,POSSUM was used to each patient to rate the results and substituted the results into Copeland equation to calculate the predicted postoperative mortality and morbidity. The actual number of complications and death were calculated after surgery and the patients were divided into one group with postoperative complications and another group without postoperative complications. The physiological score and the operative risk score were compared between the two groups. Actual number of complications and death were compared with thenumber predicted by POSSUM respectively. The clinical factors related to the actual number of complications and death were analyzed. Results Among 179 patients, there were postoperative complications in 78 patients. The physiological score and the operative severity score were significantly higher in the group in whose complications occurred compared with those without complications (16.11±2.53 points versus 14.88±1.86 points for physiological score,P=0.000 ; 13.47±2.83 points versus 12.88±2.57 points for operative severity score,P=0.000). There was no statistical difference in complication between the predicted and actual number (65/179 versus 78/179,χ2=1.968,P=0.161). There was statistical difference in death between the predicted and actual number(12/179 versus 3/179,χ2=5.636,P=0.018).Univariable analysis revealed that 5 single factors were related to the complications, only hemoglobin was related to the death. Conclusion The POSSUM gives satisfactory prediction in morbidity rate but overrates the mortality rate in primary lung cancer patients undergoing surgery, and 5 single clinical factors show a better clinical value.
