Although nearly half of these patients are stage 1 at the time of diagnosis1, the 5-year survival rate is 20 %. Curative surgical treatment supported by adjuvant oncological therapy is important. In this study we aim to presented prognosis and survival of five cases who were diagnosed as sarcomatoid carcinoma of the lung. Material - Methods: We rewieved retrospectively the clinicopathological data of five patients (3 men, 2 women) with a mean age 62.4 ( 47-76 years) with pulmonary sarcomatoid carcinoma who was treated from January 2005 to December 2012 in our clinic. The prognosis and age, sex, smoking history, tumor size, treatment modality and survival was analyzed by patient hospital data. Results: The tumor in three cases located in the right upper lobe, while two cases were in the left lower lobe. In four cases anatomical resection performed, one case is performed only diagnostic “Video-assisted thoracic surgery " because of the advanced stage. All patients died due to metastasis or tumor progression during the follow-up period. Median tumor diameter, survival time, disease-free survival time and length of stay in the hospital were 5.7 ± 1.7 cm (range 3.5 to 8 cm), 8.6±6.9 months (range 2-18 months), 4.8±4.3 months (range 0 -10 months), 5.2 ± 3.9 days (range 4-12 days), respectively. Median SUVmax (Maximum Standardized Uptake Value) value was measured 16.9 ± 11.2 (range 8.5 to 36.2 ) in main tumor. Discussion: Although ‘Sarcomatoid types of lung cancer’ are extremely rare, they have a poor prognosis and their clinical and pathological features have not been fully highlighted. Anatomic resection with curative intent and adjuvant oncologic treatments seems to be only chance for long term survival rates in these cases. In the future, gene studies and immunotherapy can give hope for a new treatment option for this poorprognosis disease. However, we need further studies with larger series of cases about these rare tumors. CR - 1. Tellioğlu E, Yücel NC, Ceylan KC, Özacarp R. Nadir Görülen Bir Akciğer Karsinomu: Dev Hücreli Karsinom.
