Objective To evaluate the incidence and to investigate risk factors of supraventricular arrhythmia (SVAs) in postoperative cancer patients in intensive care unit ( ICU ). Methods Data of 570 patients consecutively admitted to oncologic surgical ICU of Cancer Hospital of Chinese Academy of Medical Sciences from Nov. 2008 to Oct. 2009 were retrospectively collected. Univariate and multivariate logistic analysis were conducted for potential factors that influenced SAVs. Results Thirteen patients with a history of atrial fibrillation (AF) were excluded and 557 patients were eligible for the study. SVAs occurred in 72 patients ( 12. 93% ). Multivariate analysis showed four independent predictors of SVAs including age ( OR = 1. 066,95%CI: 1. 034 - 1. 099,P ＜0. 001 ) ,a history of coronary heart diseases ( OR = 2. 644,95% CI: 1. 459 - 4. 790,P ＜ 0. 05), sepsis ( OR = 2. 374,95% CI: 1. 098 - 5. 135, P ＜ 0. 05 ) and intra-thoracic procedure ( OR =2. 322,95 % CI: 1.061 - 5.084, P ＜ 0. 05 ) . ICU length of stay, severity ( APACHE Ⅱ scores in SVAs patients) were significantly greater in patients who were not affected by SVAs ( ICU stay: [2 ( 1 ～ 77 )]vs [3 ( 1 ～ 40 )]days,P ＜ 0. 001; APACHE Ⅱ score: [9 (0 ～ 37 )] vs [11 (3 ～ 38 )], P = 0. 001 ). Nine cases died in SVAs patients ( 12. 5% ) and 19 died in the non-SVAs patients (3.9%), with significant difference between the two groups( x2 = 9. 673, P = 0. 002). Conclusion In oncologic surgical ICU, the incidence of SVAs is high. Age,history of coronary heart diseases, sepsis and intra-thoracic procedure were independent rsik factors of SVAs. SVAs prolong ICU length of stay. SVAs is a marker of critical illness severity.

BACKGROUNDWith the improvement of instrument and operative technique, video-assisted thoracoscopy is more and more widely used. The aim of this study is to summarize and discuss the results of video-assisted thoracoscopic surgery (VATS) in 76 patients with thoracic tumors.

METHODSThe data of 76 cases were analyzed retrospectively. From July 1997 to June 2004, 76 patients (46 men and 30 women) with thoracic tumors underwent VATS for peripheral pulmonary nodules (52), leiomyoma of esophagus (10), mediastinal lymphadenectasis (6), malignant pleural fluid (5), bronchogenic cyst (1), mediastinal cyst (1), neurofibroma (1).

RESULTSAll procedures were performed successfully under VATS except for 8 cases, who were converted to thoracotomy for lung cancer. There was no mortality or severe complication in this series.

CONCLUSIONSVATS is a safe and effective technique in selected patients with thoracic lesions. The overall incidence of perioperative complication is low. VATS has obvious advantages in treatment of benign thoracic lesions, however, the indications should be selected carefully for malignant tumors.

Objective To investigate the clinical effects of treating traumatic lesions of the popliteal artery by staged stretching.Methods From July 2011 to March 2016,29 patients with traumatic lesion of the popliteal artery underwent staged stretching after direct end to end anastomosis at Department of Orthopaedics,The 9th People's Hospital of Wuxi.They were 19 males and 10 females,with a mean age of 38.3 years (range,from 16 to 61 years).The average length of popliteal artery lesions was 3.7 cm (range,from 2 to 5 cm).After the keen joint was immobilized at flexion by external fixation,direct end to end anastomosis was performed with a proper segmental vascular freedom.From 4 weeks after operation,the popliteal artery was stretched stage by stage to its original length by gradual adjustment of the external fixation till the knee joint was fully extended.The color,skin temperature,pulp tension and capillary reaction of the toes were closely observed after surgery.CT angiography (CTA) was performed 6 months after surgery.The active range of motion was assessed at 12 months after surgery for the knee and ankle joints on the injured limb.Results All the patients were available for an average follow-up of 2 years (range,from 1 to 3 years).Blood supply was good for all the affected limbs.The staged stretching of the popliteal artery resulted in no rupture of any anastomotic stoma or no thrombus.CTA at 6 months after surgery showed fine patency of the popliteal artery and no formation of false aneurysm or arteriovenous fistula.At 12 months after surgery,the knee function was excellent in 15 cases,good in 10 and fair in 4;the ankle function was excellent in 18 cases,good in 8 and fair in 3.Conclusion Staged stretching is a safe,convenient and effective treatment of traumatic lesions of the popliteal artery.

BACKGROUNDLung wedge resections and biopsies are frequently needed to diagnose and treat benign or malignant lung lesions. This study aims to compare thoracoscopy with thoracotomy for lung biopsy and wedge resection in solitary pulmonary nodule (SPN).

METHODSA controlled retrospective study was performed in this hospital. Patients with clinical diagnosis of SPN were undergone thoracoscopy or thoracotomy. Data of operation time, hours of stay in recover room, duration and volume of chest tube drainage, accuracy of biopsies, days of hospitalization and the whole cost of hospitalization were evaluated.

RESULTSAll patients were received lung biopsies and wedge resections (thoracoscopy 26,thoracotomy 47), and they were diagnosed pathologically. The days of hospitalization were similar in the two groups. The minutes of operation had no significant difference (thoracoscopy: 103.9±29.4 minutes, thoracotomy: 94.7±33.9 minutes). Both groups had equivalent duration of chest tube drainage (thoracoscopy: 60.3±25.0 hours, thoracotomy: 62.5±20.1 hours, P =0.687) . The total volume of chest tube drainage showed no difference in both groups. The hours of stay in recover room (thoracoscopy: 75.4±21.6 hours, thoracotomy: 80.4±17.7 hours, P =0.287) and days of hospitalization after operation (thoracoscopy: 11.3±3.4 days, thoracotomy: 10.6±2.4 days, P = 0.304 ) were not different significantly. The whole cost of thoracoscopy was 17 800.2±6 038.9 CNY and thoracotomy was 17 677.4±6 327.8 CNY ( P = 0.936 ).

CONCLUSIONSThere is no significant difference in outcomes for thoracoscopy and thoracotomy approaches. Both thoracoscopy and thoracotomy are acceptable procedures for lung biopsy and wedge resection in solitary pulmonary nodules.

OBJECTIVEThe aim of this study was to detect the plasma concentration of OLC1 (overexpressed in lung cancer 1) protein as a potential cancer biomarker, and evaluating its clinical application value in the diagnosis of non-small cell lung cancer (NSCLC).

METHODSWe prepared OLC1 antibody with OLC1 full length protein, in 5-6-week old Bal B/c mice. Each mouse was immunized four times at a dose of 15-30 µg antigen protein, and the interval between two consecutive immunizations was two weeks. Antibody screening was made by ELISA and Western blot, and a double antibody sandwich ELISA kit was developed. We used this established ELISA kit to detect the plasma concentration of OLC1 protein in 281 NSCLC patients and 92 gender- and age-matched healthy controls. Area under the receiver operating characteristic curve (AUC) was used to evaluate the detection efficacy of OLC1.

RESULTSWe obtained 11 OLC1 monoclonal antibodies and successfully established the ELISA kit to detect the plasma concentration of OLC1 with a detection range from 1.95 ng/ml to 62.50 ng/ml. OLC1 concentration in the case group (124.69 ng/ml) was significantly higher than that in the control group (67.07 ng/ml, P < 0.001). In the scenario of distinguishing NSCLC from control group, AUC result was 0.69. When the cut-off was set at 67.72 ng/ml, the sensitivity and specificity was 84.4% and 51.1%, respectively. In term of distinguishing early lung cancer (IA) from normal controls, the AUC, sensitivity and specificity were 0.68, 77.8% and 54.4%, respectively.

CONCLUSIONThe plasma concentration of OLC1 protein is significantly elevated in NSCLC patients. OLC1 may be as a potential cancer biomarker applied in clinical diagnosis.

OBJECTIVETo summarize surgical treatment of lung cancer patients with poor pulmonary function.

METHODSFrom 1991 to 1999, 181 lung cancer patients with poor pulmonary function underwent operation. The correlation between the results of preoperative pulmonary functional tests and the postoperative cardiopulmonary complications was analyzed by Chi-square test (chi(2)).

RESULTSIn 181 patients, pneumonectomy was done in 43, lobectomy in 118, partial lung resection in 16 and exploration in 4. The postoperative complication and mortality rates of the resection group were 42.3% (75/177) and 7.9% (14/177). The cardiopulmonary complication rates were 25.6%, 48.3%, 31.3% in pneumonectomy, lobectomy and partial lung resection. The morbidity and mortality rates of 8 patients who received preoperative chemotherapy and/or radiotherapy were 75.0% and 37.5%. The morbidity and mortality rates of 12 patients who had had a previous history of thoracotomy were 66.7% and 33.3%. In the present series, the 1-, 3- and 5-year survival rates were 71.1%, 42.2% and 31.1%. The 5-year survival rates of patients with stage I, II and III lesions were 55.0%, 25.0% and 0.

CONCLUSIONPreoperative spirometry is an important evaluation test for lung cancer patients with poor pulmonary function. It should be evaluated in combination with other pulmonary function tests such as CO(2) diffusion and cardiopulmonary excise tests, etc whenever possible. Patients with a history of thoracotomy, chemotherapy and radiotherapy should be carefully evaluated before operation to avoid high morbidity and mortality. Stage I and II lung cancer patients with poor pulmonary function can undergo operation if they have been well managed preoperatively and well taken care of with nursing care perioperatively.

BACKGROUNDWith the improvement of the surgical and anesthetic techniques, there are increasing numbers of elderly surgical patients with lung cancer. The purpose of this study is to examine the prognostic factors of surgical resection in patients more than 70 years of age.

METHODSData were retrospectively analyzed from 192 patients aged ≥70 years who underwent lung cancer surgery. Of these patients, 48.4% were in stage I, 20.8% in stage II, 19.3% in stage III, and 2.1% in stage IV. Patient demographics were the following: 79.2% male and 20.8% female; 21.9% ≥75 years older; and 11.5% had significant co-morbidities. Tumor characteristics: squamous cell carcinoma 49.0%, adenocarcinoma 35.9%, adenosquamous carcinoma 8.3%, small cell lung cancer 4.7%, others 2.1%.

OPERATIONSexploration 2.1%, wedge resection 8.3%, lobectomy 72.4%, more than lobectomy 12.5%, pneumonectomy 4.7%. Of these operations, 91.1% were radical surgery. The significance of prognostic factors was assessed by univariate and multivariate COX regression analyses.

RESULTSThe total 5-year survival rate was 33.5% in this series. Age, sex, symptom and co-morbidity had no impact on survival. Multivariable COX analysis demonstrated that incomplete resection (P=0.003), advanced surgical-pathological stage (P < 0.001) and other type of the tumor (P=0.016) were significant, independent, unfavorable prognostic determinants in patients.

CONCLUSIONSThoracic surgery is a safe and feasible approach in elderly patients with lung cancer. Every effort should be made to detect early stage patients who might benefit from surgical treatment. Lobectomy is still the ideal surgical option for elderly patients who are able to tolerate the procedure. More limited lung surgery may be an adequate alternative in patients with associated co-morbidities.
