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.

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.

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.

[ Abstract] Objective To investigate the clinical efficacy of preoperative three-dimensional radiotherapy (3DRT) with or without concurrent chemotherapy for esophageal carcinoma.Methods We retrospectively analyzed 103 esophageal carcinoma patients who received preoperative 3DRT with or without concurrent chemotherapy from 2004 to 2014 in Cancer Hospital CAMS.The median radiation dose was 40 Gy, and the TP or PF regimen was adopted for concurrent chemotherapy if needed.The overall survival (OS) and disease-free survival ( DFS) were calculated by the Kaplan-Meier method, and the survival difference and univariate prognostic analyses were performed by the log-rank test.The Cox proportional hazards model was used for multivariate prognostic analysis.Results The number of patients followed at 3-years was 54.The 3-year OS and DFS rates were 61.1% and 54.9%, respectively, for all patients.There were no significant differences between the 3DRT and concurrent chemoradiotherapy (CCRT) groups as to OS (P=0.876) and DFS (P=0.521).The rates of complete, partial, and minimal pathologic responses of the primary tumor were 48.0%, 40.2%, and 11.8%, respectively.There were significant differences in OS and DFS between the complete, partial, and minimal pathologic response groups (P=0.037 and 0.003). No significant difference in pathologic response rate was found between the 3DRT and CCRT groups (P=0.953).The lymph node metastasis rate was 26.5%, and this rate for the complete, partial, and minimal pathologic response groups was 14%, 30%, and 67%, respectively, with a significant difference between the three groups (P=0.001).The OS and DFS were significantly higher in patients without lymph node metastasis than in those with lymph node metastasis (P=0.034 and 0.020).The surgery-related mortality was 7.8% in all patients.Compared with the 3DRT group, the CCRT group had significantly higher incidence rates of leukopenia (P=0.002), neutropenia (P=0.023), radiation esophagitis (P=0.008), and radiation esophagitis ( P=0.023).Pathologic response of the primary tumor and weight loss before treatment were independent prognostic factors for OS and DFS (P=0.030,0.024 and P=0.003,0.042). Conclusions Preoperative 3DRT alone or with concurrent chemotherapy can result in a relatively high complete pathologic response rate, hence increasing the survival rate.Further randomized clinical trials are needed to confirm whether preoperative CCRT is better than 3DRT in improving survival without increasing the incidence of adverse reactions.

The pathogenesis of aplastic anemia(AA)is complex and associated with hematopoietic stem cell defect,abnormal bone marrow microenvironment,immune dysfunction,and somatic mutation,in which the immune mechanism plays an important role.This article reviews the pathogenesis of AA from the following aspects:regulatory T cell reduction,hematopoietic stem cell reduction caused by factor-related apoptosis/factor-related apoptosis ligand signaling pathway,aberrant target gene expression induced by inflammatory factor-stimulated microRNAs,and regulatory T cell dysfunction,so as to provide ideas and methods for clinical practice.

Objective To analyze the clinical value of postoperative radiotherapy for node-positive middle thoracic esophageal squamous cell carcinoma ( TESCC ) and to modify the target volume .Methods A total of 286 patients with node-positive middle TESCC underwent radical surgery in Cancer Hospital, Chinese Academy of Medical Sciences, from 2004 to 2009.In addition, 90 of these patients received postoperative intensity-modulated radiotherapy.The Kaplan-Meier method was used to calculate survival rates, and the log-rank test was used for survival difference analysis.The Cox model was used for multivariate prognostic analysis.The chi-square test was used for comparing the recurrence between patients receiving different treatment modalities.Results The 5-year overall survival ( OS) rates of the surgery alone ( S) group and surgery plus postoperative radiotherapy ( S+R) group were 22.9%and 37.8%, respectively, and the median OS times were 23.2 and 34.7 months, respectively ( P=0.003) .For patients with 1 or 2 lymph
node metastases (LNMs), the 5-year OS rates of the S group and S+R group were 27.3%and 44.8%, respectively ( P=0.017);for patients with more than 2 LNMs, the 5-year OS rates of the S group and S+R group were 16.7%and 25.0%, respectively (P=0.043).The peritoneal lymph node metastasis rates of N1 , N2 , and N3 patients in the S group were 2.9%, 10.9%, and 20.0%, respectively ( P=0.024) .The S+R group had a significantly lower mediastinal lymph node metastasis rate than the S group ( for patients with 1 or 2 LMNs:8.0%vs.35.3%, P=0.003;for patients with more than 2 LNMs, 10.0%vs.42.3%, P=0.001) , and had a prolonged recurrence time compared with the S group ( 25.1 vs.10.7 months, P=0.000) .However, for patients with more than 2 LNMs, the S+R group had a significantly higher hematogenous metastasis rate than the S group (46.7%vs.26.1%, P=0.039).Conclusions Patients with node-positive middle TESCC could benefit from postoperative radiotherapy.The target volume can be reduced for patients with 1 or 2 LNMs.Prospective studies are needed to examine whether it is more appropriate to reduce the radiotherapy dose than to reduce the target volume for patients with more than 2 LNMs.A high hematogenous metastasis rate warrants chemotherapy as an additional regimen.
