    Abstract:
    Approximately 1 per 1,000-1,500 pregnancies is complicated by maternal malignancies. Metastatic involvement of the products of conception is a rare event. There have been 62 cases of placental and/or fetal metastatic involvement originating from maternal cancer reported since 1866. Only 14 cases of lung cancer associated with pregnancy have been documented. We report on an additional case involving the products of conception, and the management of lung cancer in pregnancy is discussed based on an extensive review of the literature. The case of a 29-year-old woman presenting during the 31(st) week of gestation with metastatic non small-cell lung cancer to the placenta, liver and bone is described. The mother was delivered by caesarean section of a healthy baby girl during her 32(nd) week of gestation. The mother's postpartum course was complicated by disseminated pulmonary and bony metastases and malignant pericardial and pleural effusions causing the patient's death within 1 month after lung cancer was diagnosed. Malignancies spreading to the products of conception are melanoma (32%), leukemia and lymphomas (15%), breast cancer (13%), lung cancer (11%), sarcoma (8%), gastric cancer (3%) and gynecologic cancers (3%), reflecting malignancies with a high incidence in women of reproductive age. All lung cancers were diagnosed with widely disseminated, inoperable neoplastic disease, including distant metastases in 46%. The mean age was 35.1 years (range, 30-45 years) and 60% of patients had a history of tobacco use. The mean survival was 7.5 months (range: 1-42 months). Placenta involvement was present in 7 out of 15 cases. Fetal involvement was reported in only one case. Because there is no evidence of a direct adverse effect of pregnancy on the course of lung cancer, we recommend delivery at a time when enough fetal maturity can be assumed and the subsequent treatment of the mother.
