Background. In cardiac disease there appears to be a difference in the
treatment of men and women, and thus an advantage in survival in men.
This study aimed to determine whether these differences exist in lung
cancer. Methods. We undertook a retrospective cohort study in a unive
rsity hospital. The study population consisted of 104 consecutive wome
n and 104 consecutive men with newly diagnosed lung cancer between Mar
ch 1988 and June 1990. The following information was collected: sex, a
ge, presenting symptoms, investigations, histology, stage, treatment,
and survival. Results. The location of the tumor, presenting symptoms,
investigations, and stages were similar in men and women. There was a
difference in the distribution of the various histologic types of lun
g cancer: Small cell lung cancer was more frequent in women (25% versu
s 11.5% in men) and squamous cell carcinoma more frequent in men (38%
in women versus 51% in men). The overall survival was similar among th
e two sexes, but there was a survival advantage in women when adjusted
for stage. Conclusions. There was a higher incidence of small cell ca
rcinoma in women and squamous cell carcinoma in men. There was evidenc
e of a difference in the survival rate of lung cancer in favor of wome
n according to stage. (Ann Thorac Surg 1998;66:1140-4) (C) 1998 by The
