Objective: Our study was planned to investigate the clinical, radiometabolic (PET-CT), and survival properties of primary lung cancer with cavitary.

Material and Method: The files of patients diagnosed as primary lung cancer in our clinic between 2014 and 2016 were examined. The cases were divided into two groups as primary lung cancer with cavity and without cavity. Demographic, radiological, clinical, radiometabolic and survival properties of both groups were recorded. The data of both groups were compared with each other.

Results: A total of 323 cases with a mean age of 61.6 ± 9.8 years were included in the study. There were 36 primary lung cancer cases with and 287 lung cancer cases without cavity. The rate of primary lung cancer with cavity was 11.1%. The rate of cavitation was significantly higher in squamous cell carcinomas (p =0.024). The size of lung cancer with cavity (65 mm) was greater than lung cancer without cavity (50 mm) Mean, maximum ? (p =0.001). Median overall survival in cavitary cancers was 14 ± 2.7 months. In non-cavitary cancers, this time was 12 ± 0.8 months (p =0.887). Ot-herwise, age, gender, smoking history, cancer stage, treatment characteristics, radiometabolic properties and survival were similar in both groups (p >0.05).

Conclusion: The most common cavitation in lung cancers is seen in squamous cell cancers. Clinical, radiometabolic and survival characteristics of cavitary lung cancers are similar to those of noncavitary lung cancer.
