Retrospective analysis of clinical pathology characteristic in patients with lung neoplasms

OBJECTIVE: To analyze the clinical pathology characteristic of patients with lung neoplasms. METHODS: A total of 1729 patients with lung neoplasms in cancer hospital, chinese academy of medical sciences from Jan. 2008 to Dec. 2008 were analyzed retrospectively including residence, age, gender, pathological types and HBV results. RESULTS: There were 1179 male patients and 550 female patients in 1729 lung neoplasms patients, including 1474 cases of lung cancer patients, 228 were benign and 27 cases of patients with unclear diagnosis. Totally 95.72% of the patients from the northern region of China. As to the pathological types, 656 patients (44.50%) were adenocarcinoma; squamous cell carcinoma and SCLC, respectively, accounting for 33.24% and 9.50%. And 68.29% of female lung cancer patients with adenocarcinoma. The most common pathological types of benign patients were inflammatory mass, totally 67 cases (29.39%). A total of 55.29% (941/1702) of lung lesions of all lung neoplasms patients were in right lung, especially the right upper lobe. The HBV infection rate was relatively stable at 4.92% in lung neoplasms patients and didn't matter with the pathological types. CONCLUSIONS: Male patients with high incidence of lung neoplasms, and the most common lesions in the right lung, especially in right upper lobe. Adenocarcinoma has become the most common pathological type in lung cancer.
