[Show abstract][Hide abstract] ABSTRACT: Since radiation and chemotherapy have limitations as therapies for malignant pleural mesothelioma (MPM). The type of surgery [extrapleural pneumonectomy (EPP), extended pleurectomy (E/P), and pleurectomy/decortication (P/D)] remains controversial.
This study involves 76 consecutive patients. 58 of the cases were males (76%) with a median age of 53.17±10.93 years. EPP, E/P, and P/D were performed in 31, 20, and 25 cases, respectively.
The median survival time was 20 months in all patients. Overall, five-year survival rate was 14.3%. The survival rate was significantly better in epithelioid mesothelioma (P=0.049). For EPP cases, the median survival rate was 17 months, and the three-to-five year survival rates were 21% and 17%, respectively. For E/P cases, the median survival rate was 27 months and the three-year and four-year survival rates were 34% and 30%, respectively. For P/D cases, the median survival rate was 15 months and the three-to-five year survival rate was 13% and 0%. There were no statistically significant differences between the three surgical techniques (P=0.088). A comparative analysis indicates only a statistically significant difference in the E/P and P/D comparison (P=0.032). Hospital mortality showed a higher trend in EPP group (EPP: 12.9%, E/P: 0% and P/D: 4%, P=0.145). N2 cases, there were no cases of two-year survival. The survival rate in N2 was comparatively much lower, which was statistically significant (P=0.005). In multivariate analysis, only P/D (OR 0.3, 95% CI: 0.1-0.9, P=0.049) and N2 (OR 1.6, 95% CI: 0.9-2.6, P=0.090) were found to be poor prognostic factors.
E/P could be encouraged to EPP with lower mortality rate and better survival trend in MPM. N2 diseases were negative prognostic factors in MPM.

[Show abstract][Hide abstract] ABSTRACT: Background
Squamous cell carcinomas confined to the bronchial wall (SCC-CBW) exhibit two distinct patterns of growth: superficially spreading and endobronchial mass lesions. We examined whether differences exist in the histopathological features and prognosis of SCC-CBW exhibiting different growth patterns. Materials and Methods
In this study, 37 cases with SCC-CBW were included. Tumors were classified into two groups: superficially spreading squamous cell carcinoma (s-SCC) and nodular squamous cell carcinoma (n-SCC). For each case, the growth pattern, T and N status, lymphovascular and perineural invasions, immunohistochemical expressions of p53 and K-i-67, and survival rates were analyzed. ResultsTwenty cases were classified as s-SCC, and 17 cases were classified as n-SCC. There was a significant relationship and correlation between the length of s-SCC in the longitudinal axis and the depth of invasion (p=0.01, R=0.557). There was a statistically significant positive relationship between the depth of invasion and the nodal status (N1 involvement) (p<0.0001, R=0.71). ConclusionsSCC-CBW exhibits variable growth patterns. However, despite this variability, there are no biological or histological differences between tumors of different growth patterns, and this variability has very little, if any, effect on survival.

[Show abstract][Hide abstract] ABSTRACT: Optimal resection type for non-small cell lung cancer (NSCLC) with interlobar lymph node involvement (ILNI) has seldom been reported. To completely resect a NSCLC with ILNI, some surgeons believe that a pneumonectomy is needed.
We retrospectively studied 151 patients (147 men, 4 women; mean age 58 ± 8 years, range 34-79) with non-small lung cancer without mediastinal or hilar lymph node metastasis who underwent an anatomic lung resection with systematic lymph node dissection between January 1995 and November 2006. All patients had involvement of the surgical-pathologic interlobar (#11) lymph node: 8 patients had a T1 tumor; 95, T2; 39, T3; and 9, T4. We evaluated the effect of resection type (pneumonectomy in 90 patients versus lobectomy in 61) on their prognosis by univariate and multivariate analyses.
The 5-year survival rate of patients was 61% for the lobectomy and 35% for the pneumonectomy (p = 0.04). We did not find statistically significant differences in sex, median age, distributions of tumor site, histology and differentiation, complete resection rate, N1 involvement status, morbidity and mortality. Patients who underwent the pneumonectomy had larger tumors and more T3 tumors. The T status, multiple levels N1 involvement and histology did not affect survival in the univariate analysis. Multivariate analysis revealed resection type as a significant prognostic factor.
Pneumonectomy was not necessary in patients with NSCLC and interlobar lymph node involvement that we had discovered intraoperatively.
[Show abstract][Hide abstract] ABSTRACT: The presence of synchronous multiple primary non-small-cell lung cancers (SMPLC) is a rare condition and the optimal treatment remains unclear. In this study, the survival of surgically treated SMPLC patients and the factors affecting survival were analyzed. Methods: Between 2001 and 2008, 26 consecutive patients diagnosed with SMPLC, who had all of their tumors resected, were retrospectively evaluated. Patients, who had bronchoalveolar carcinoma or carcinoid tumors and satellite nodules, were excluded. Prognostic factors were analyzed using univariate and multivariate analyses.
The tumors were unilateral in 14 and bilateral in 12 patients. In total, 38 procedures were performed. A complete resection was achieved in 35 (92.1%) procedures. The in-hospital mortality rate was 7.6% (two patients). The overall 5-year survival rate was 49.7%, and the median survival time was 40 months. The 5-year survival rate was 40.6% for unilateral and 62.8% for bilateral SMPLC patients (p = 0.47). Histopathologic tumor type, N1 nodal disease, tumor (T) status, and older age did not influence survival. There was no survival disadvantage for patients, upon whom a sublobar resection had been performed. There was a trend toward poorer survival in patients upon whom a pneumonectomy had been performed (p = 0.12). The 3-year survival rate for patients, who received adjuvant chemotherapy and/or radiotherapy (66.7%), was better than other patients (56.3%). In the multivariate analysis, we found a trend toward poor survival in patients, who received a pneumonectomy, and a trend toward better survival in patients, who received adjuvant therapy (p = 0.05 and p = 0.06).
The survival of SMPLC patients, who were treated surgically, was satisfactory. Pneumonectomy was a poor prognostic factor, whereas adjuvant therapy was a good prognostic factor.

[Show abstract][Hide abstract] ABSTRACT: Background: We evaluated the prognostic role of main bronchial extension of right upper lobe tumors in patients with non-small cell lung cancer (NSCLC). Methods: Between 1998 and 2007, the results of surgery in 302 patients with right upper lobe NSCLC were investigated retrospectively. One-hundred-sixty-nine patients with completely resected pT2 o r p T3 tumor without lymph node metastasis were analyzed. The patients were divided into three groups; patients with NSCLC staged as pT2 (n=82), pT3 with invasion of the main bronchus (pT3-MB; n=41), and pT3 patients without main bronchial involvement (n=46). Results: The five-year survival rate of patients with pT3-MB was 36.7%, whereas it was 55.1% for patients with pT2 and 50.7% for patients with other pT3 tumor (p=0.28). Survival of the patients who had undergone pneumonectomy was poorer than that of others (p<0.01). The hilar or interlobar N1 was found to be predictive for poor prognosis (p<0.001). Conclusion: The survival of patients with resected right upper lobe NSCLC with pT3-MB is poor. Our study confirmed that extralobar N1 i s f requently s een a nd i t worsens the prognosis. This coexistence could be the another reason of poor prognosis in patients with main bronchus invaded T3 tumor.

[Show abstract][Hide abstract] ABSTRACT: The European Society of Thoracic Surgeons (ESTS) has proposed preoperative lymph-node staging guidelines (LNSGs) for non-small-cell lung cancer (NSCLC) based on the introduction of new staging modalities into clinical practice. The validity of these guidelines was assessed.
Among the patients (n=185) with histologically confirmed NSCLC diagnosed between 2007 and 2009, who were suitable for thoracotomy, the 168 who underwent computed tomography (CT) of the chest and CT-integrated positron emission tomography (PET-CT) were included in the study. The preoperative mediastinal stage was confirmed by mediastinoscopy in all patients. A thoracotomy was done for mediastinoscopy-negative patients. The mediastinal staging results were adapted to the ESTS-LNSG (direct thoracotomy for T1-2 N0 tumour according to CT and PET-CT and invasive staging for others) and the validity of the guidelines was tested.
In this series, the overall mediastinal lymph-node metastasis (MLNM) prevalence was 29.2%. If the guidelines had been applied, thoracotomy without invasive mediastinal staging would have been done in only 11 (6.5%) patients, and no MLNM would have been detected. Mediastinoscopy would have been performed in 157 patients and MLNM would have been found in 41 (26%). In the 116 mediastinoscopy-negative patients, MLNM would have been detected after thoracotomy in an additional eight patients. Thus, the sensitivity, specificity, and positive and negative predictive values of the guidelines were calculated as 84%, 100%, 100% and 94%, respectively.
The preoperative LNSGs for NSCLC proposed by the ESTS are effective.

[Show abstract][Hide abstract] ABSTRACT: The effects of angiogenesis on survival were assessed by measuring the tumor microvessel density and vascular endothelial growth factor expression in patients with resected stage I non-small cell lung carcinoma.
The study population included 141 patients who underwent complete resection for stage pT1 and T2 N0 M0 tumors between 1999 and 2007. Lobectomy and pneumonectomy were performed in 131 and 10 patients, respectively. Tumor specimens were analyzed immunohistochemically for staining with anti-CD105 antibody to determine tumor microvessel density and anti-vascular endothelial growth factor antibody to determine the vascular endothelial growth factor expression level. Univariate and multivariate analyses were performed for factors influencing patients' survival.
The overall 5-year survival was calculated as 68%, with rates of 76.9% for patients with T1 disease and 66.2% for patients with T2 disease (P = .4). The vascular endothelial growth factor expression rate was 94.3% for patients with stage I non-small cell lung carcinoma. Vascular endothelial growth factor expression did not influence survival (P = .9). The median microvessel density of the tumors measured based on the level of CD105 expression was 19.8. The effect of microvessel density on survival was significant (P = .02). The 5-year survivals of patients with tumors with 20 or more microvessels and less than 20 microvessels were 76.8% and 56.1%, respectively; this difference was highly significant (P = .004). The microvessel density was determined as an independent factor influencing survival on multivariate analysis (P = .03).
The level of vascular endothelial growth factor expression in tumors was not a successful predictor of survival in patients with resected stage I non-small cell lung carcinoma. A high microvessel density based on CD105 is a strong predictor of prognosis in these patients.

We present a case of contralateral hematoma after left posterolateral thoracotomy as a rare and enigmatic complication.
[Show abstract][Hide abstract] ABSTRACT: Due to its rarity there is no clear policy on the management of spontaneous pneumomediastinum (SPM).
We treated 23 SPM patients between January 1 996 and November 2 006. There were 20 males and 3 females and their mean age was 27. Clinical records of the patients were collected and analyzed.
The most frequent symptoms were neck swelling (n = 20) and rhinolalia (n = 15). Onset of the symptoms was acute. A preceding factor was found in 19 (83 %) patients; these included vigorous cough, forced physical activity, vigorous sneezing and enormous efforts during spontaneous vaginal delivery. Chest X-ray was sufficient to show mediastinal free air in 18 patients. Computerized chest tomography showed pneumomediastinum in all patients. Twenty patients were treated expectantly. Subcutaneous air drainage was needed to drain massive subcutaneous emphysema in three patients.
Acute onset of typical symptoms, the existence of a preceding factor and the exclusion of other possible causes of pneumomediastinum with the help of CT are sufficient to make a diagnosis of SPM. A surgical intervention is generally not needed for the treatment of this entity.

[Show abstract][Hide abstract] ABSTRACT: Patients with N1 non-small cell lung cancer represent a heterogeneous population with varying long-term survival. To better define the importance of N1 disease and its subgroups in non-small cell lung cancer staging, we analyzed patients with N1 disease using the sixth edition and proposed seventh edition TNM classifications.
From January 1995 to November 2006, 540 patients with N1 non-small cell lung cancer who had at least lobectomy with systematic mediastinal lymphadenectomy were analyzed retrospectively.
For completely resected patients, the median survival rate and 5-year survival rate were 63 months and 50.3%, respectively. The 5-year survival rates for patients with hilar N1 (station 10), interlobar (station 11), and peripheral N1 (stations 12 to 14) involvement were 39%, 51%, and 53%, respectively. Patients with hilar lymph node metastasis showed a shorter survival period than patients with peripheral lymph node involvement (p = 0.02). Patients with hilar zone N1 (stations 10 and 11) involvement tended to show poorer survival than patients with peripheral zone N1 (12 to 14) metastasis (p = 0.08). Multiple-station lymph node metastasis indicated a poorer prognosis than single-station involvement (5-year survival 39% versus 51%, respectively, p = 0.01). Patients with multiple-zone N1 involvement showed poorer survival than patients with single-zone N1 metastasis (p = 0.04). A significant survival difference was observed between N1 patients with T1a versus T1b tumors (p = 0.02). Multivariate analysis revealed that only multiple-station lymph node metastasis was predictive of poor prognosis (p = 0.05).
Multiple-station versus single-station N1 disease and multiple-zone versus single-zone N1 involvement indicate poorer survival rate. Patients with hilar lymph node involvement had lower survival rates than patients with peripheral N1. The impact of T factor seemed to be veiled by the heterogenous nature of N1 disease. Further studies of adjusted postoperative strategies for different N1 subgroups are warranted.

[Show abstract][Hide abstract] ABSTRACT: This study aims to investigate the treatment modalities and factors influencing survival in surgically treated superior sulcus tumors.
Sixty-five cases of surgically treated non-small cell carcinoma of the lung occurring as superior sulcus tumors between 1994 and 2007 were retrospectively reviewed. Twenty-five patients underwent induction radiotherapy (RT), 10 had induction chemoradiotherapy (CT/RT). In thirty patients surgery was performed directly. The mortality rate was 6.2 %. Pathological stage was T3 in 55, T4 in 10, N0 in 52, and N1 in 5 and N2 in 8 patients.
Overall 5- and 10-year survival rates were 31 % and 28 %, respectively. Complete resection rate was 90 % for patients who received induction CT/RT and 80 % for patients who either received induction RT alone or patients in whom surgery was performed directly. In patients who received neoadjuvant therapy with complete tumor resection, the median survival time was 33 months (28 months for patients who received induction RT alone and 36 months for patients who received induction CT/RT), and the 5-year survival rate was 41 %. Median survival time and 5-year survival rate of patients treated by direct surgery with complete resection was 24 months and 37 %, respectively ( P = 0.87). Five-year survival and 10-year survival rates were significantly higher after complete resection than after incomplete resection (38 % and 34 % vs. 0 %, P = 0.0001). In multivariate analysis, only N2 disease ( P = 0.04) and incomplete resection ( P = 0.03) were found to be poor prognostic factors.
The presence of N2 disease and incomplete resection are the two most important factors affecting survival. Induction CT/RT may increase the ability to achieve complete surgical resection.

[Show abstract][Hide abstract] ABSTRACT: Pleural effusion due to congestive heart failure (CHF) typically are transudates. Light's criteria may be insufficient in determining if the pleural effusion is transudative or exudative in patients with CHF. The aim of our study was to assess the diagnostic performance of the amino-terminal fragment of pro-brain natriuretic peptide (NT-proBNP) in pleural fluid and serum for the identification of pleural effusion owing to heart failure.
The study prospectively evaluated NT-proBNP in serum and pleural fluid from patients with effusion owing to heart failure (n=51) and other causes (n=64). Measurements were made of levels of NT-proBNP by an electrochemiluminiscence immunoassay. The discriminative properties of NT-proBNP levels in identifying pleural effusion due to heart failure were determined by receiver operating characteristic curve (ROC) analysis and compared to the diagnostic value of finding a transudate by Light's criteria and serum-pleural fluid albumin gradients.
Serum and pleural fluid NT-proBNP levels were significantly elevated in patients with pleural effusion owing to heart failure. The area under ROC for the diagnosis of pleural effusion from heart failure was similar for pleural fluid (0.973, 95% CI: 0.914-0.995) and serum (0.968, 95% CI: 0.890-0.989) NT-proBNP.
NT-proBNP levels in either pleural fluid or serum have high diagnostic values and they are easily useable parameters in the diagnosis of heart failure-related pleural effusion.

[Show abstract][Hide abstract] ABSTRACT: Introduction: Primitive neuroectodermal tumors (PNETs) are rare, rapidly progressive, small- round cell tumors with a poor prognosis despite multimodal therapy, including surgery and chemoradiotherapy. The treatment of choice was unknown since no clinical series with surgical therapy had been reported. We evaluated the impact of multimodal treatment in patients with PNETs located in the thoracic region.
Methods: Between 1998 and 2006, 25 patients with PNETs in the thoracic region were treated in 3 tertiary-care hospitals. The patients consisted of 15 males and 10 females with a mean age of 27.2 years (range, 6-60). The tumor was in the chest wall in 20 (involving the costovertebral junction in 9), the lung in four, and the heart in one patient. Twelve patients received neoadjuvant chemotherapy (54.5%), and 22 of 25 patients underwent surgery.
Results: In patients who received neoadjuvant treatment, the mean regression rate was 65.4% (range, 30-100%). Eighteen (82%) patients underwent chest wall resection, while 7 (32%) had vertebral resections, and the remaining 4 (16%) had pulmonary resections. A complete resection was possible in 18 of 22 patients (82%). Patients with incomplete and complete resections had 25% and 56% 5-year survival rates, respectively (p = 0.13). The progression-free 3-year survival rate was 36% and the median survival time was 13 months. The complete resection rate was significantly higher in patients receiving neoadjuvant therapy (p = 0.027). The 5-year survival rate of the patients with or without neoadjuvant therapy was 77% and 37%, respectively (p = 0.22) although it prolonged the disease-free survival (p = 0.01). The 5-year survival rate of patients without costovertebral junction involvement was 66%, whereas patients with PNETs involving the costovertebral junction had a 21% 3-year survival. The difference was statistically significant (p = 0.01). The 5-year progression-free survival rate of patients without costovertebral junction involvement was 58%, whereas patients with PNETs involving the costovertebral junction had a 14% 1-year progression-free survival (p = 0.004).
Conclusions: PNET is an aggressive malignancy that often requires multimodal therapy. Induction chemotherapy leads to a greater complete resection rate and better disease-free survival, while involvement of the costovertebral junction indicates a poorer survival.

[Show abstract][Hide abstract] ABSTRACT: Most parathyroid glands in hyperparathyroidism can be resected through a cervical approach. In approximately 2% of cases, the ectopic gland is in the mediastinum in a location that requires a thoracic approach. Advancement in video-assisted thoracoscopic surgical (VATS) techniques has decreased the need for sternotomy to successfully remove these ectopic glands. We describe a case involving a 29-year-old woman with hyperparathyroidism resulting from an ectopic mediastinal parathyroid adenoma that caused neonatal hypocalcemia, which was removed through VATS.
[Show abstract][Hide abstract] ABSTRACT: The aim this study is to determine the characteristics, survival, and factors affecting the survival of resected T3 non-small cell lung cancer.
The records of 97 cases were retrospectively reviewed with T3 non-small cell lung cancer patients that were operated between 1996-2001. Complete resection was achieved in 71 (73.2%) patient. The distribution of N status was 47.4%, 28.9%, and 23.7% for N0, N1 and N2 respectively. The evaluated prognostic factors in univariate and multivariate analyses were, histologic type, type of resection, N status, subgroups of pT3, resection margins and effect of adjuvant therapy.
Overall 5-year survival rate was 24.3%. Median survival and 5-year survival of the patients whose tumors resected completely was 33 months and 31.5%, whereas 18 months and 7.3% for the patients resected incompletely (P=0.03). Median survival being not significantly different among the three subgroups: 25, 23, and 32 months (P=0.7) in the bronchial pT3, mediastinal pT3, and peripheral pT3 subgroups, respectively. Histology (P=0.57), type of surgical resection (lobectomy versus pneumonectomy) (P=0.25), and use of adjuvant therapy (P=0.054) did not influence the survival significantly. However N status influenced the survival significantly (P=0.01). According to the multivariate analyses, two factors were selected as prognostic indicators: N2 status (P=0.03) and incomplete resection (P=0.03).
Three pT3 subgroups did not show survival differences. Complete resection and N2 status are the two most influencing factors in survival of the patients. Adjuvant therapy effected the survival and the quality of life reversely.
