Does preoperative chemotherapy for lung cancer increase surgical morbidity?
C+S did not significantly affect morbidity or mortality overall, based on clinical stage, postoperative stage, or extent of resection. The potential for enhanced survival in resectable NSCLC justifies continued study of C+S.
We find support for our hypothesis that the disproportionate high mortality levels of specific male subpopulations are the central cause of the current extent of sex differences in life expectancy. Thus, public health programmes should be targeted toward these disadvantaged subpopulations among men which seem to be related primarily to socioeconomic characteristics.
