Many patients with early stage lung cancer (stage I and II) are curable by surgical resection. In patients with locally advanced disease surgery plays an important role in order to provide local tumor control. Therefore, the aim of all staging efforts in NSCLC must be to identify all patients, who might be potential candidates for a surgical approach. ⋯ With respect to lymph node staging, VATS is complimentary to cervical mediastinoscopy because it helps to stage the lymph nodes in the A-P. window (#5, 6), as well as the lymph nodes paraesophageal (#8) and in the pulmonary ligament (#9). In conclusion, surgical staging methods provide a 100% specificity in combination with a high sensitivity and only a minimal morbidity. Currently, surgical staging is recommended by the majority of scientific societies for the staging of patients with apparently resectable NCSLC.

A retrospective study was conducted analyzing the clinical outcome and various prognostic factors in patients treated with gamma knife stereotactic radiosurgery (GK-SRS) for solitary brain metastasis from non-small cell lung carcinoma (NSCLC). A total of 72 patients from June of 1992 to January of 1999 were treated. All patients received GK-SRS to a median dose of 18Gy, with 45 patients receiving additional whole-brain radiation therapy. ⋯ In conclusion, patients presenting with a solitary metachronous brain metastasis from NSCLC achieved longer survivals than those with a synchronous metastasis. The tail in the survival curves demonstrates that a prolonged survival may be attained in patients with solitary metastases from NSCLC. This study adds to the growing body of literature that supports the use of SRS in the management of this patient population.

We report a phase II study to evaluate the survival rate, response rate and toxicity of concurrent chemoradiation therapy (CCRT) followed by consolidation chemotherapy (CT) with oral etoposide and cisplatin for patients with locally advanced inoperable non-small cell lung cancer (NSCLC). Fifty-four patients with locally advanced inoperable NSCLC who had received no prior therapy were enrolled into this trial between May 1995 and December 2000. Treatment consisted of two cycles of concurrent CT and four cycles of consolidation CT with oral etoposide (50 mg/m2) on days 1-14 during the CCRT courses and on days 1-21 during the consolidation CT courses, plus cisplatin (75 mg/m2 i.v.) on day 1 of a 28-day cycle. ⋯ After a median follow-up duration of 50 months (range 20-85), the median overall survival time was 15.3 months (95% CI, 9.7-20.8), and the 1-, 2-, 3-, and 5 year overall survival rates were 62, 40, 30 and 16%, respectively. The duration of median progression-free survival was 12.3 months (95% CI, 7.4-17.3), and the 1-, 2-, 3-, and 5-year progression-free survival rates were 47, 40, 29 and 23%, respectively. Thus, concurrent conventional chest radiotherapy with oral etoposide plus cisplatin followed by consolidation CT led to an encouraging survival rate and prolongation of the time to progression, with moderate toxicity in patients with locally advanced inoperable NSCLC.

To investigate the relationship between the clinical features and prognosis in young patients with lung cancer who underwent resection. ⋯ Young patients with lung cancer were more often seen in male than in female. Squamous cell carcinoma accounted for the most part, no statistical difference, however, compared with adenocarcinoma and small cell carcinoma. The pneumonectomy rate in young patients was remarkably higher than that in patients older than 40. The postoperative 5-year-survival in young patients was considerably higher than in patients older than 40 who underwent surgery during the same period. Favorable prognosis was seen in patients with squamous cell carcinoma and undergoing absolutely curative resection, while worse outcome in stage III cancer.

Comparative Study Clinical Trial
Histopathological evaluation of fluorescence bronchoscopy using resected lungs in cases of lung cancer.
Objective evaluation of the performance of autofluorescence bronchoscopy based on analysis of thin sections of the bronchus of resected lungs was performed and compared with the results of preoperative autofluorescence bronchoscopy. Conventional bronchoscopy and autofluorescence bronchoscopy were performed prior to surgery for lung cancer. Thin sections of the bronchus were obtained from the resected specimens. ⋯ The specificity of white light and autofluorescence was 88 and 84%, respectively. The diagnostic accuracy of autofluorescence bronchoscopy was objectively confirmed. Autofluorescence examination showed better sensitivity for cancerous/precancerous lesions and the evaluation of the extent of cancer invasion was accurate.
