ABSTRACT
The clinical data of 18 patients with PB from April 1989 to April 2013 was analyzed retrospectively, including 11 men and 7 women, aged 45 and 76 years old (mean 53 years). There were 12 cases of PB occurring in right lung and other cases in left lung. Among them, 3 patients had no symptoms, and 15 patients displayed symptoms of cough, chest pain, asthenia or minor haemoptysis. Overall, 11 patients had a preoperative diagnosis of lung cancer, 7 patients were preoperatively diagnosed as the other diseases, which included lung benign tumor (n=5) and mediastinal mass (n=2). All patients received a radical resection. Six patients received postoperative cisplatin-based chemotherapy, and two patients received postoperative irradiation with the dose of 55 Gy. Histologically, 14 cases of 18 patients had biphasic pulmonary blastoma and four cases had well differentiated fetal adenocarcinoma. A total of 12 patients died in a period of 6-36 months after operation, and 1 case was lost after 2 years of follow up. The median survival time was 19 months. PB is a rare primary lung malignant embryonal neoplasm. Despite its assumed embyonal origin, the tumor has a predilection for adults. A preoperative correct diagnosis is very difficult in spite of modern diagnostic imaging and biopsy techniques. Surgical resection is the main method for diagnosis and treatment. Postoperative chemotherapy or irradiation can help eliminate tumor remnants. Its prognosis is very poor, especially for the biphasic type.
