In the United States, it causes more cancer-related deaths than the next four causes （breast cancer, prostate cancer, colon cancer, and pancreatic cancer） of cancer-related mortality combined （1）. About 30% of people have already progressed to stage III lung cancer and 40% to stage IV at the time they are diagnosed （2）. Although chest X-ray and sputum cytology, when applied in health check-ups, can identify some relatively small tumors, they are not able to lower the overall mortality （3）. More recently,展开更多

Methods: From December 2009 to March 2011, 20 patients with peripheral lung cancer were treated with single-direction thoracoscopic lobectomy and systemic lymph nodes dissection. Results: Surgeries were successfully performed. No significant complications occurred perioperatively. The average operation time was 193 min, the average blood loss was 234 ml, the average duration of drainage was 6 d, the postoperative hospital stay was 12 d, and the average number of lymph nodes dissected was 16. Conclusion: Single-direction thoracoscopic lobectomy is feasible and safe in the treatment of peripheral lung cancer and can simplify the surgical procedures.展开更多

Methods： We retrospectively analyzed 401 patients with pathological diagnoses of NSCLC who underwent lobectomy, bilobectomy, or pneumonectomy with systematic lymphadenectomy from March 2004 to June 2011 in our hospital. All of the patients enrolled had a SPN preoperatively. Information about the primary tumor location, lymph node metastasis, and other baseline data were collected. Stepwise logistic regression was used to identify the key factors indicating non-regional mediastinal lymph node metastases （NRM）. Results： Of the primary tumors, 117, 39, 74, 104, and 67 were in the right upper lung （RUL）, right middle lung （RML）, right lower lung （RLL）, left upper lung （LUL）, and left lower lung （LLL）, respectively. Stepwise regression showed that #2,4, #10,11, and #10,11 as well as #7 was the key lymph node station for RUL, LUL, and lower lobes： #2,4 [odds ratio （OR）=28.000, 95% confidence interval （CI）： 2.917-268.790, P=0.004] for RUL, #10,11 （OR=31.667, 95% CI： 2.502-400.833, P=0.008） for LUL, #10,11 （OR=19.540, 95% CI： 4.217-90.541, P〈0.001） and #7 （OR=7.395, 95% CI： 1.586-34.484, P=0.011） for lower lobes, respectively. Patients with tumors 〉2 cm rarely had NRM without primary regional mediastinal involvement. Conclusions： With rigid consideration, a lobe-specific lymphadenectomy is feasible in practice. This protocol can be used when the lobe-specific key nodes are negative in intraoperative frozen sections, especially for NSCLC diagnosed as SPN 〈2 cm preoperatively.展开更多
