Retrospective analysis of 1470 cases with lung cancer diagnosed by fibrobronchoscopy

Objective To evaluate the significance of fibrobronchoscopy for the diagnosis of lung cancer and explore the relationship of pathological types of lung cancer with sex, age and clinical diagnosis. Methods The pathological diagnose data of 1470 patients with lung cancer diagnosed by fibrobronchoscopy was retrospectively analyzed. Results Out of the 1470 patients 1007 were male (68.50 per cent), 463 were female (31.50 percent). The age of the eldest patient was 87, the youngest was 17, average age was 57.41. Among the data of pathological diagnose, the percentage of squamous carcinoma was the largest, which was 39.52 percent (581 cases), adenocarcinoma was 25.44 percent (374 cases), small cell lung cancer was 24.35 percent (358 cases), quesonable lung cancer is 5.71 percent (84 cases), lung cancer that difficult to typing was 2.11 percent (31 cases), other pathological types was 2.86 percent (42 cases). The number of male with lung cancer was significantly greater than that of female (P 0.01). Male was susceptible to squamous carcinoma(P 0.01), while female was more susceptible to adenocarcinoma and small cell lung cancer(P 0.01, (P 0.05). Conclusion The fibrobronchoscopic examination is very important in the pathological diagnosis of lung cancer; The pathological type is different in different age and sex.
