Objective

Retrospective study on the relation between the use of blood products and survival rates in patients treated surgically for stage I non-small cell lung cancer (NSCLC).

Patients and methods

The study included 856 patients who underwent surgical resection from 1969 to 2000 for stage I NSCLC, classified histologically according to the current guidelines of the Spanish Society of Pulmonary and Thoracic Surgery (SEPAR). Patients who died in the postoperative period were excluded from the study. A series of clinicopathological variables were recorded, including the perioperative use or not of blood products. Descriptive, univariate, and multivariate statistical analyses were performed. Follow up concluded in December of 2003.

Results

One hundred twenty-five patients (14.6%) underwent a perioperative transfusion. A significant association was found between the use of blood products and tumor size (P<.001), pneumectomy (P<.001), and cell type (P<.05). The respective 2, 5, and 10-year survival rates were 78%, 63%, and 54% for the nontransfusion group, and 73%, 59%, and 46% for the transfusion group. Both survival curves were compared and no significant differences were found (P = .23). Multivariate regression analysis included tumor size, patient age, and histologic cell type (squamous cell carcinoma or not); no relation between transfusion and survival was found.

Conclusions

In our series, we found no difference in survival rates for patients with stage I NSCLC after perioperative blood transfusion.

Objetivo

Estudio retrospectivo sobre la influencia del uso de hemoderivados en la supervivencia del carcinoma broncopulmonar no anaplásico de células pequeñas (CB-NACP) en estadio I sometido a tratamiento quirúrgico.

Pacientesy métodos

Se incluyó en el estudio a 856 pacientes (1969-2000) diagnosticados de CBNACP, que se resecaron y clasificaron como estadio I patológico según la actual normativa SEPAR, y se excluyó la mortalidad postoperatoria. Se recogieron una serie de variables clinicopatológicas, incluida la utilización o no de hemoderivados en el perioperatorio, y se aplicaron análisis estadísticos descriptivos, univariante y multivariante. El seguimiento finalizó en diciembre de 2003.

Resultados

En el perioperatorio se transfundió a 125 pacientes (14,6%). La utilización de hemoderivados se relacionó significativamente con el tamaño tumoral (p < 0,001), la realización de una neumonectomía (p < 0,001) y el tipo histológico (p < 0,05). La supervivencia fue del 78, el 63 y el 54% a los 2, 5 y 10 años, respectivamente, para el grupo de pacientes no transfundidos, y del 73, el 59 y el 46% para el grupo de transfundidos. La comparación de ambas curvas de supervivencia no mostró diferencias significativas (p = 0,23). En el análisis multivariante entraron en regresión el tamaño tumoral, la edad y la variedad histológica epidermoide/no epidermoide. En este análisis no se demostró ninguna relación de la transfusión con la supervivencia.
