015. Ethical dilemmas, medical protocols and deontology in diagnosis of lung cancer during pregnancy

Background: Lung cancer is second in frequency in both sexes, with very poor prognosis and high mortality rates. Smoking is the main cause. Malignant neoplasms of the lung on pregnancy are not very frequent. They constitute a direct threat for the woman’s life and simultaneously the outcome of pregnancy is doubtful.

Objective: We present this case because of the rarity of coexistence of lung neoplasm and pregnancy, in absence of treatment guidelines. The question of overcoming, by the attending physician, the ethical dilemmas and the medical protocols is apposed, in the progress and outcome of pregnancy, when lung malignant neoplasm coexists.

Methods: A 33-year-old woman, smoker, with occasional alcohol consumption and medical history of Leiden thrombophilia, is at 18-19 weeks of gestation. She presents to the emergency department of the general hospital with reported episodes of dyspnea and cough. She refers cough with difficulty in the elimination of sputum, dyspnea, orthopnea, facial and neck edema with venous distension, common symptoms of superior vena cava syndrome. The CT scan revealed a lung mass in the right upper lobe with the right hilum involved. The rest of the staging was negative.

Results: The first bronchoscopy revealed edema in the main carina and right upper lobe stenosis while the biopsy samples did not demonstrate a histological identification. Mediastinoscopy was followed and revealed a poorly differentiated carcinoma (primary pulmonary neuroendocrine tumor). Both patient and relatives consented to start chemotherapy treatment. After four cycles of chemotherapy with carboplatin + etoposide, the patient in the 7^th month of gestation, gave birth to a healthy baby boy weighted 1,130 gr. The patient died after four months because she suffered from an extremely aggressive tumor with brain and diffused spinal metastatic infiltrations and also from the appearance of paraneoplastic disorders like Lambert-Eaton myasthenic syndrome.

Conclusions: The successful outcome of pregnancy with coexisting malignant lung neoplasm is an achievable target, even though seems rather impossible. It is required a conscious overcoming, not only of the lack of existing treatment guidelines but also by the involving of the ethical dilemmas that may arise.
