BACKGROUND The significance of allogeneic blood transfusion in the prognosis of patients with nonsmall lung carcinoma (NSCLC) remains controversial. Reports have suggested that patients with adenocarcinoma have a worse prognosis from cancer than patients with squamous cell carcinoma (SCC), but this evidence is lacking in NSCLC. The objective of the current study was to elucidate the correlation between perioperative allogeneic blood transfusion and the prognosis in patients with adenocarcinoma and SCC. METHODS The study group comprised 329 consecutive patients (172 men and 157 women) with a mean age of 67 years who underwent lung resection between 1996 and 2003 in 1 unit. The clinicopathologic and survival data were compared between 62 patients (42.7%) with adenocarcinoma and 58 patients (48.3%) with SCC who received a perioperative blood transfusion and 83 patients (57.3 %) with adenocarcinoma and 126 patients (61.3%) with SCC who did not. RESULTS The overall surgical mortality rate was 3.9% (13 deaths). The median surgical blood loss was 380 mL (range, 125–4500 mL). The mean blood transfusion received was 1.9 U (range, 0–8 U). The overall actuarial 1, 3, and 5‐year survival rates in the adenocarcinoma and SCC groups were 82.3%, 49.6%, and 19.4% and 87.9%, 71.7%, and 32.7%, respectively ( P = 0.021). Multivariate analysis demonstrated that the factors that appeared to be independent prognostic factors in both groups were T‐classification ( P < 0.001), lymph node metastasis ( P < 0.001), and postoperative complications ( P = 0.029). Perioperative blood transfusion was not an independent prognostic indicator in either group. CONCLUSIONS The current study demonstrated that long‐term survival in patients with adenocarcinoma of the lung was significantly worse compared with patients with SCC, but was independent of allogeneic perioperative blood transfusion. The results reaffirmed the importance of tumor invasion and lymph node involvement in the overall poor prognosis of these patients. Cancer 2004. © 2004 American Cancer Society.
