  1. Second primary cancers related to smoking and treatment of small-cell lung cancer.

    Article - En anglais

    Background 

    An increased risk of second primary cancers has been reported in patients who survive small-cell carcinoma of the lung.

    The treatment's contribution to the development of second cancers is difficult to assess, in part because the number of long-term survivors seen at any one institution is small.

    We designed a multi-institution study to investigate the risk among survivors of developing second primary cancers other than small-cell lung carcinoma.

    Methods 

    Demographic, smoking, and treatment information were obtained from the medical records of 611 patients who had been cancer free for more than 2 years after therapy for histologically proven small-cell lung cancer, and person-years of follow-up were cumulated.

    Population-based rates of cancer incidence and mortality were used to estimate the expected number of cancers or deaths.

    The actuarial risk of second cancers was estimated by the Kaplan-Meier method.

    Results 

    Relative to the general population, the risk of all second cancers among these patients (mostly non-small-cell cancers of the lung) was increased 3.5-fold.

    Second lung cancer risk was increased 13-fold among those who received chest irradiation in comparison to a sevenfold increase among nonirradiated patients.

    It was higher in those who continued smoking, with evidence of an interaction between chest irradiation and continued smoking (relative risk=21). (...)
