Abstract： Objective To investigate clinical characteristics， surgical strategy and prognosis of pulmonary pleomorphic carcinoma， and improve the diagnostic and therapeutic level of pulmonary pleomorphic carcinoma. Methods We retrospectively analyzed clinical data of 7 patients with pulmonary pleomorphic carcinoma who underwent surgical resection from January 2006 to August 2011 in West China Hospital of Sichuan University. There were 5 male patients and 2 female patients with the male/female ratio of 2.5︰1.0 and the mean age of 58.85 （43-69） years old. We also conducted a literature review through PubMed using pulmonary pleomorphic carcinoma and surgery as the key words， and 8 patients with integral clinical data from 2005 to 2011 were identified. There were 7 male patients and 1 female patient with the male/female ratio of 7︰1 and mean age of 70.25 （51-79） years old. All the patients underwent surgical resection and systemic lymph node dissection. Results The mean age of this group was 64.93 （43-79） years old. Among the 15 patients， there were 12 males and 3 females with the male/female ratio of 4︰1. The main symptoms were cough， blood in phlegm， hemoptysis and chest pain. Pathology diagnosis confirmed pleomorphic carcinoma in all the patients. Among the 7 patients of our hospital， there were 3 patients with spindle cell with squamous cell carcinoma， 2 patients with spindle cell with adenocarcinoma， and 2 patients with spindle cell with large cell carcinoma and adenocarcinoma. During follow-up， 3 patients died with the longest survival time of 49 months， and the other 4 patients were still alive. Among the 8 patients in the literature review， there were 4 patients with spindle cell with squamous cell carcinoma， 1 patient with spindle cell with adenocarcinoma， 1 patient with spindle cell with large cell carcinoma and squamous cell carcinoma, and 2 patients with spindle cell with adenocarcinoma and squamous cell carcinoma. During follow-up， 5 patients died with the longest survival time of 22 months， and the other 3 patients were still alive. Conclusion Pulmonary pleomorphic carcinoma is extremely rare and surgical resection is an effective treatment strategy for it.
Objective To investigate the impact of complete video-assisted thoracoscopic lobectomy and open lobectomy on perioperative heart rate （HR） and blood oxygen saturation （SO2） of lung cancer patients，and explore whether minimally invasive surgery can enhance postoperative recovery of lung cancer patients. Methods A total of 138 lung cancer patients were chosen from 161 consecutive patients with pulmonary diseases who were admitted to West China Hospital of Sichuan University between September 2010 and December 2011. According to different surgical approach，all the 138 lung cancer patients were divided into routine thoracotomy group （thoracotomy group，70 patients including 53 males and 17 females with their average age of 56.1±9.7 years） and complete video-assisted thoracoscopic lobectomy group （VATS group，68 patients including 46 males and 22 females with their average age of 53.4±6.5 years）. There was no statistical difference in preoperative clinical characteristics between the 2 groups. Preoperative and postoperative （1st，3rd，7th and 30th day） numeric pain rating scale （NPRS），HR and SO2 were compared between the 2 groups. Results （1） There was no statistical difference in NPRS on the 1st and 3rd postoperative day between the 2 groups （3.83±0.79 vs. 3.93±0.67， 2.88±0.59 vs. 3.03±0.71，P＞0.05），but on the 7th and 30th postoperative day，NPRS of the thoracotomy group was signi- ficantly higher than that of VAST group （1.61±0.33 vs. 1.22±0.12，1.58±0.26 vs. 1.19±0.31，P＜0.05）. （2） Postop- erative sedentary HR of both VATS group and thoracotomy group were significantly higher than preoperative levels ［（84.13±17.21） / minute vs. （73.67±10.32）/minute， （86.13 ±19.67） / minute vs. （72.24±14.21） / minute， P＜0.05］. Postoperative HR of VATS group decreased to preoperative level on the 3rd postoperative day，while postoperative HR of the thoracotomy group decreased to preoperative level on the 7th postoperative day. （3） There was no statistical difference between preoperative and postoperative （all the time points） sedentary SO2 of both VATS group and thoracotomy group （96.34 %±2.11% vs. 97.12%±2.31%，95.33%±4.13% vs. 94.93% ±4.31%，P＞0.05）.（4） The changes of HR and SO2 before and after exercise of VATS group were significantly smaller than those of the thoracotomy group on the 3rd postoperative day ［（11.11±4.81）/minute vs. （18.23±6.17）/minute，3.1%±1.2% vs. 7.4 %±2.7%，P＜0.05］ . Conclusion The impact of complete video-assisted thoracoscopic lobectomy on cardiopulmonary function is comparatively smaller，which is helpful for postoperative fast-track recovery of lung cancer patients.
