Objective To study the short-and long-term outcomes of high platelet count in patients with colorectal cancer after surgery. Methods A total of 398 patients with colorectal cancer who complied with the requirements for this study and operated in professional group on colorectal surgery of Gastrointestinal Surgery Center of West China Hospital in Sichuan University from January 2009 to October 2009 were retrospectively included in this study. Based on the last preoperative platelet count, these patients were divided into normal platelet group(100×109/L-300×109/L)and high platelet group( > 300×109/L). The short-and long-term outcomes were analyzed and compared between two groups. Results ①The gender, age, histological type, degree of differentiation, diameter of tumor, site of tumor, and operation method had no significant differences between two groups(P > 0.05), but the ratio ofⅢ, Ⅳstages of TNM in the high platelet group was significantly higher than that in the normal platelet group(P < 0.05).②The first exhaust time and defecation time of the normal platelet group was significantly shorter than those of the high platelet group(P < 0.05). The time of the first oral intake, the time of pull out the drainage, ureter, and nasogastric tube, the time of the first ambulation, and hospitalstay had no significant differences between two groups(P > 0.05).③The total complications rate and single complication rate had no significant differences between two groups(P > 0.05).④All the patients were followed-up with average following-up time 58 months, there were 7 patients with recurrence and 35 patients with death in all the followed-up patients, the recurrence rate and death rate in the high platelet group were significantly higher than those in the normal platelet group(3.5% versus 1.1%, P=0.013; 15.7% versus 6.0%, P=0.002). Conclusions There is a relationship of platelet count to colorectal malignant degree. The recovery time of gastrointestinal function is longer, and the local recurrence rate and the postoperative death rate are higher for the patients with high platelet count.
