Background: Adenosquamous carcinoma of the lung is a rare pathologic type of lung cancer. The aim of this study is to explore the clinical features of adenosquamous carcinoma of the lung.
Methods: A total of 115 patients with adenosquamous carcinoma of the lung were retrospectively analysed, who were diagnosed by operation and pathology.
Results: Among the 36 female patients, 7 were under 49 years (19.44%). There were 14 patients (12.17%) without any symptom and 16 patients had residual carcinoma at the resection margin (14.04%). The degree of lymph node metastasis was 37.51%. The proportion of stage III patients was 54.78%.
Conclusions: The incidence of adenosquamous carcinoma of the lung in young women (under 49 years, especially under 39 years) is rather high. The residual carcinoma at the resection margin often occurs after routine operation. The degree of lymph node metastasis is rather high.
