[Diagnosis and management of lung cancer during pregnancy]

The incidence of lung cancer during pregnancy is very low, but it is becoming more frequent in industrialized countries both because of the increase in smoking in young women and because women are becoming pregnant later in life. Usually, the cancer has a poor prognosis due to the presence of metastatic disease at the time of diagnosis. Diagnosis and management are delicate, and should deal with the gestational age, the maternal prognosis, the fetal toxicity of treatments, but also with the worsening of maternal prognosis and the risk of neoplastic cells being transmitted to the fetus in case of delayed treatment. Psychological and ethical considerations complicate the decision process. We present a review of the epidemiology, clinical characteristics, management, and prognosis concerning lung cancer during pregnancy. Finally, it is important to remember that young women with lung cancer should be advised to use a reliable form of contraception.
