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 1 729 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 1 179 male patients and 550 female patients in 1 729 lung neoplasms patients,including 1 474 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%(941/1 702) 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.
