The Characteristic of the Lung Cancer of 44 Young Patients Observed by Fibrobronchoscopy and Clinical Analysis

To study the clinical features and the characteristic of fibrobrochoscopy in young patients with lung cancer. Methods: We retrospectively summarized the clinical data of 44 young lung cancer patients enrolled between January 1995 and October 2000. Results: 84.09% of patients showed the positive results by fibrobronchoscopy, whereas the negative patients were 15.91%.81.08%of the positive patients had direct sign with mass opacities in x-ray. 18.92% with mass and reticular-nodular opacities had direct sign. The chest radiographs of young lung cancer patients presented basically mass opacities (43.18%), hydrothorax opacities (20.45%) .flaky opacities (18.18%) .double lobes reticular-nodular opacities (13.64 %), and atelectatic opacities (4.55%). According to pathologic classification, 50 % were pulmonary adenocarcino-ma, 36.36% were non-differentiated small-cell lung cancer, 13.64% were squamous cell carcinoma. 61.36% were left lung cancer, and 25% were right lung cancer. 13.64% were bronchiolo-alveolar carcinoma. Illb, IV stage (72.73%) were more than II, IIIa stage (27.27% ). Conclusion: The unique clinical symptoms haven't been found in young patients with lung cancer. They are prone to be misdiagnosed pneumonia or tuberculosis. Therefore, it is necessary to pay more attention to the lung cancer of young patients.
