Increased platelet counts after transthoracic en bloc resection for esophageal cancer is associated with significantly improved survival


Ling, Frederike C; Vallböhmer, Daniel; Hoelscher, Arnulf H; Schmidt, Daniel; Bollschweiler, Elfriede; Schneider, Paul M (2010). Increased platelet counts after transthoracic en bloc resection for esophageal cancer is associated with significantly improved survival. World Journal of Surgery, 34(11):2628-2634.

Abstract

Background: We analyzed perioperative platelet counts as a potential clinical marker for survival after transthoracic en bloc resection for esophageal cancer. Recent data described preoperative thrombocytosis in malignancies to be associated with poor prognosis. Methods: A retrospective analysis from a prospective database (1997-2006) was performed for 291 consecutive patients with esophageal cancer who underwent transthoracic en bloc esophagectomy and extended lymphadenectomy. Squamous cell cancer was found in 47.0% and adenocarcinoma in 50.9% (2.1% had rare histologies). Neoadjuvant chemoradiation was performed in 152 (52%) patients. Platelet counts before surgery and on postoperative days (PODs) 1, 10, and 30 were evaluated. We used the published cutoff value of 293×109/l (mean of 80 healthy controls±standard deviation) for platelet counts. Results: High platelet counts before surgery missed significance for poorer survival (p=0.054). Following a perioperative fall in thrombocytes, a significant rise at POD 10 after surgery was evident. Platelet counts of more than 293×109/l at this time correlated with a significantly improved survival rate (p=0.027). Patients with no increase in thrombocytes until POD 10 had significantly poorer survival (p=0.012). Multivariate analysis confirmed that a thrombocyte increase between the preoperative count and that on POD 10 is an independent prognostic indicator (p=0.035) for patients with completely (R0) resected tumors. Conclusions: An increase in platelet counts measured on POD 10 following transthoracic en bloc esophagectomy and extended lymphadenectomy is an independent prognostic indicator for improved survival in patients with esophageal cancer
