Background
In non-small cell lung cancer (NSCLC), the well-developed epidermal growth factor receptor (EGFR) is an important therapeutic target. EGFR activating gene mutations have been proved strongly predictive of response to EGFR-tyrosine kinase inhibitors (TKI) in NSCLC. However, both in daily clinical practice and clinical trials, patients with unknown EGFR gene status (UN-EGFR-GS) are very common. In this study, we assessed efficacy and tolerability of sequential treatment of first-line pemetrexed followed by icotinib in Chinese advanced lung adenocarcinoma with UN-EGFR-GS.Patients and methods
We analyzed 38 patients with advanced lung adenocarcinoma with UN-EGFR-GS treated with first-line pemetrexed-based chemotherapy followed by icotinib as maintenance or second-line therapy.Results
The response rates to pemetrexed and icotinib were 21.1% and 42.1%, respectively. The median overall survival was 27.0 months (95% CI, 19.7-34.2 months). The 12-month overall survival probability was 68.4%. The most common toxicities observed in icotinib phase were rashes, diarrheas, and elevated aminotransferase. Subgroup analysis indicated that the overall survival is correlated with response to icotinib.Conclusions
The sequence of first-line pemetrexed-based chemotherapy followed by icotinib treatment is a promising option for advanced lung adenocarcinoma with UN-EGFR-GS in China. 相似文献2.

Objective
Few treatment options are available for advanced non-small cell lung cancer (NSCLC) patients who have failed of gefitinib or erlotinib treatment in second/third-line treatment. The aim of this study was to investigate the efficacy of re-administration of the same TKI after failure of gefitinib or erlotinib.Patients and methods
The clinical data of 33 patients with advanced NSCLC were retrospectively analyzed. All of the patients were given the same TKI treatment after the failure of gefitinib or erlotinib. Survival analysis was evaluated by Kaplan-Meier method.Results
Twenty patients (60.6%) were re-administration with gefitinib as the 2nd EGFR-TKI, and thirteen patients (39.4%) received erlotinib. One patient (3.0%) showed partial response (PR), 14 (42.4%) achieved stable disease (SD), and 18 (54.5%) had progressive disease (PD). The disease control rate was 45.5% and the median progression-free survival was 1.5 months (95% CI: 0.6-2.3 months). The PFS in patients who got disease control in the prior TKI was 2.2 and 1.2 months in the progression disease cases (P=0.29), the DCR was 54.5% and 27.3% in two group, respectively (P=0.26).Conclusions
Re-administration of TKI seems to be a potential therapeutic option for treatment of selected advanced NSCLC patients after failure of gefitinib or erlotinib, especially for the patients with NSCLC who once responded from the prior TKI treatment.KEY WORDS : Non-small cell lung cancer (NSCLC), erlotinib, gefitinib, retreatment, efficacy 相似文献3.

Background
Crizotinib has been associated with intracranial disease control in anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer (NSCLC) patients with brain metastases. Continued crizotinib treatment has also been used for prolonged disease control in patients experiencing isolated central nervous system (CNS) failure. However, there are few studies of crizotinib efficacy in ALK-positive Chinese patients. Thus, we retrospectively investigated the clinical efficacy of crizotinib in Chinese ALK-positive NSCLC patients with brain metastases at baseline, and evaluated the clinical benefit of continuing crizotinib beyond CNS failure.Methods
A total of 120 advanced ALK-positive NSCLC patients treated with crizotinib were enrolled with 38 having brain metastases at baseline. The objective response rate (ORR) and progression-free survival (PFS) were compared between patients with and without brain metastases at baseline. A subset of patients who developed CNS failure continued crizotinib treatment beyond progressive disease (PD), and the second PFS from the time of the first progression was also evaluated.Results
The ORR of crizotinib was similar between patients with and without brain metastases at baseline (68.4% vs. 69.5%, P=0.904). However, the patients without brain metastases at baseline experienced a longer median PFS [10.0 months, 95% confidence interval (CI), 7.6-12.5 vs. 7.0 months, 95% CI, 6.4-7.6; P=0.021]. Among 88 patients with PD defined Response Evaluation Criteria in Solid Tumors (RECIST), 33 developed CNS failure. A total of 24 patients who developed CNS failure continued crizotinib treatment beyond PD, and they achieved a second median PFS of 6.3 months (95% CI, 2.9-9.7).Conclusions
Chinese ALK-positive NSCLC patients with brain metastases achieved a similar response to crizotinib and significantly shorter PFS compared to those without brain metastases at baseline. Continuous administration of crizotinib beyond PD in patients developing CNS failure appeared to be a valid treatment strategy. 相似文献4.

Background
The aim of this study was to examine the effect of hydration with magnesium and mannitol without furosemide on the nephrotoxocity accompanying combination chemotherapy using cisplatin and pemetrexed in patients with advanced non-small cell lung cancer (NSCLC).Methods
Fifty patients with NSCLC who received cisplatin plus pemetrexed, using either old hydration protocol including normal saline with mannitol and furosemide, or a new one including normal saline with magnesium and mannitol without furosemide were retrospectively analyzed. Nephrotoxicity was compared between patients treated using the old protocol and those treated with the new protocol. Univariate and multivariate analyses were performed to identify the independent factors associated with protection against nephrotoxicity in patients with NSCLC who received cisplatin plus pemetrexed.Results
Thirty patients received the old hydration protocol, while 20 patients were treated using the new hydration protocol. The patients treated using the new hydration protocol showed a significantly greater increase in creatinine clearance (P=0.0004) and a decrease in the serum creatinine level (P=0.0148) after one course of chemotherapy compared with those treated using the old hydration protocol. There were no differences in the chemotherapeutic response or overall survival between the groups (P=0.572). The new hydration protocol with supplemented magnesium with mannitol without furosemide was an independent factor for the protection against nephrotoxicity induced by cisplatin and pemetrexed in patients with advanced NSCLC [HR 0.232 (95% CI: 0.055-0.986), P=0.039].Conclusions
These results demonstrate that the new hydration protocol comprising supplementation with magnesium without furosemide could prevent the nephrotoxicity induced by cisplatin and pemetrexed without affecting the treatment outcome.KEY WORDS : Lung cancer, cisplatin, magnesium, nephrotoxicity, pemetrexed 相似文献5.

Background
The aim of the present study was to explore the association between the pretreatment globulin albumin ratio (GAR) and the survival of advanced non-small cell lung cancer (NSCLC) patients.Methods
Patients hospitalized between January 2007 and December 2010 were enrolled and eliminated according to the inclusion and exclusion criteria. GAR was defined as the absolute globulin value divided by the absolute albumin value. Chi-squared test was performed to compare clinical characteristics in different groups. Kaplan-Meier and Cox regression model were used to determine independent prognostic factors. A P value of ≤0.05 was considered to be statistically significant.Results
Total 316 patients were finally enrolled. The median progression free survival (PFS) and overall survival (OS) were 210.0 and 430.0 days, respectively. The statistical analyses indicated that pretreatment GAR >0.58 [hazard ratio (HR) =1.52, 95% confidence interval (95% CI): 1.12-2.08, P=0.008 for PFS, HR =1.65, 95% CI: 1.20-2.26, P=0.002 for OS], and pretreatment albumin ≤35 g/L (HR =2.09, 95% CI: 1.20-3.65, P=0.003 for PFS, HR =1.92, 95% CI: 1.10-3.36, P=0.022 for OS) were independent prognostic factors for both PFS and OS.Conclusions
Our study first established a connection between pretreatment GAR and advanced NSCLC patients, suggesting that GAR was an independent prognostic factor and could be the biomarker for prognosis. 相似文献6.

Background
Cyberknife stereotactic radiosurgery is an emerging noninvasive technique for treating oligometastatic cancer. The aim of this study is to evaluate the efficacy and tolerability of cyberknife for the treatment of patients with lung metastases.Materials and methods
A total of 134 lung metastases in 95 patients were treated with cyberknife in the radiotherapy center of our hospital from March 2009 to March 2013. The number of lung metastases per patient ranged from one to four (single lesions in 63 patients, 66.3%). The average tumor volume was 14.6 cm3 and the prescribed radiation dosage ranged from 30 to 60 Gy, fractionated one to five times with a 60% to 88% isodose line. The primary end point was local control (LC); secondary end points were survival and toxicity.Results
The median follow-up was 17 months (ranging from 4 to 46 months). The 1-year LC rate was 97.6%, the 2-year LC rate was 90.6%, and the 3-year LC rate was 87.0%. The median survival time was 38.0 months and the median progression-free survival (PFS) time was 14.0 months. The 2-year PFS rate was 29.0% and the overall survival (OS) rate was 61.3%. No grade 4 or higher toxicity was encountered.Conclusions
Cyberknife is safe and effective treatment for patients with lung metastases. 相似文献7.

Objectives
Non-small-cell lung cancer (NSCLC) patients harboring sensitive epidermal growth factor receptor (EGFR) mutations derive greater benefits from EGFR-tyrosine kinase inhibitors (EGFR-TKIs) than those with wild type tumors. However, whether EGFR mutation status is associated with the efficacy of cytotoxic chemotherapy or prognosis in advanced NSCLC patients remained controversial. Thus, we sought to conduct a meta-analysis to answer this question.Methods
Electronic databases were searched for eligible literatures. The primary outcomes were objective response rate (ORR) and 6-month progression-free survival (PFS) rate. The pooled odds ratio (OR) was calculated using random-effects model. Subgroup analyses stratified by study types, EGFR mutation detection methods, chemotherapy regimens, and patient origins were proposed.Results
A total of 14 studies involving 1,772 advanced NSCLC patients with known EGFR mutation status who had received first-line chemotherapy were included. Patients with positive EGFR mutation had numerically higher ORR than wild type patients (36.2% vs. 30.1%) without significant differences (OR 1.24, 95% CI, 0.90 to 1.70; P=0.19). However, patients with EGFR mutants had significantly superior 6-month PFS rate than wild-type patients (58.6% vs. 47.2%; OR 1.88, 95% CI, 1.33 to 2.65; P=0.0003). Results of the subgroup analyses were concordant with the overall ones.Conclusions
This comprehensive analysis revealed that advanced NSCLC patients with sensitivity EGFR mutation had higher 6-month PFS rate and potentially greater ORR compared with wild-type patients after first-line chemotherapy. It suggested that EGFR mutation status should be considered a significant factor for patient stratification in evaluating the efficacy of antitumor agents in addition to EGFR-TKIs. 相似文献8.
Background
To assess the effect of preoperative neoadjuvant therapy on resectability, downstaging, and the prognosis in patients with stage IIIA-N2 non-small cell lung cancer (NSCLC).Methods
Eighty-four patients who underwent resections after induction therapy [76 with neoadjuvant chemotherapy (CTx) and 8 with induction chemoradiotherapy (CRTx)] for clinically evident [larger than 1 cm on computed tomography (CT)] and pathologically confirmed ipsilateral N2 positive NSCLC (stage IIIA) between January 2009 and July 2013 were reviewed retrospectively.Results
Partial response (PR) was observed in 39 patients (46.4%). Standard lobectomy was performed in 63 cases (75.0%), and extensive resection was conducted in 21 cases (25.0%), including four pneumonectomies. Pathologic nodal downstaging (pN2 to pN0-1) was confirmed in 38 cases (45.2%). After induction therapy plus resection, 5-year progression-free survival (PFS) and overall survival (OS) in cases with radical resections were 37.9% and 34.2%, respectively. Patients who underwent lobectomy or pathologic nodal downstaging had better prognosis than those who had extensive resection or persistent N2 in PFS (P=0.036; P=0.025) and OS (P=0.023; P=0.024). On univariate analysis, lobectomy and pathological nodal downstaging were favourably predictive factors both in PFS and OS. Cox multivariate analyses identified only pathologic nodal downstaging to predict better PFS, and lobectomy to be significantly prognostic for OS.Conclusions
These data suggest that neoadjuvant therapy was feasible, and helpful for tumor and pathologic nodal downstaging with promising rates of survival in patients with stage IIIA-N2 NSCLC. After induction therapy, patients with potentially radical lobectomy were more likely to benefit from operation. Pathological nodal downstaging of pN2 to pN0-1, rather than clinical response was predictive of a favorable outcome, and was correlated with a better chance of survival. 相似文献9.

Background
Tegafur-uracil (UFT) is an anticancer agent that inhibits thymidylate synthase (TS). The degree of TS expression in primary lung cancer (LC) is different according to histologic cell type. In this study, we examined the variability of the anti-tumor efficacy of UFT monotherapy depending on histological subtypes of LC.Methods
In the current single-institution, retrospective study, we assigned the patients with LC to three histologic groups [the squamous (Sq) non-small cell lung cancer (NSCLC)] group, the non-Sq NSCLC group and the SCLC group] and then compared the clinical response to UFT monotherapy between the three groups.Results
Our clinical series of 149 patients include 54 cases of Sq NSCLC, 67 cases of non-Sq NSCLC and 28 cases of SCLC. For Sq NSCLC, non-Sq NSCLC and SCLC group, the overall response rates (ORRs) were 1%, 1% and 0% (P=0.522), respectively. The disease control rates (DCRs) were 38.9%, 31.3% and 10.7% (P=0.012), respectively. The median progression-free survivals (PFSs) were 2.68, 2.25 and 1.46 months (P=0.004 for three groups and P=0.773 for two groups except for the SCLC group at the log-rank test), respectively. There was no significant difference between the groups in median overall survival (OS).Conclusions
Our results indicate that the degree of the anti-tumor effect of UFT was higher in patients with NSCLC as compared with SCLC. But it showed no significant difference between the patients with Sq NSCLC and those with non-Sq NSCLC. 相似文献10.
Background
The efficacy of induction treatment plus surgery for improving postoperative survival in patients with non-small-cell lung cancer (NSCLC) in stages IIIA-N2 is controversial, especially compared with the combined chemotherapy and radiotherapy. We therefore performed a systematic review and meta-analysis of the published phase III randomized clinical trials (RCTs) to quantitatively evaluate the survival benefit of preoperative induction treatment vs. combined chemoradiotherapy.Methods
We systematically searched for trials that started after January, 1980. We excluded relevant studies using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) standards. Our primary endpoint, overall survival (OS), was defined as the time from randomisation until death (any cause). Secondary endpoint was progression free survival (PFS). PubMed, EMBASE and Cochrane library were used for the study search. All analyses were by intention to treat.Results
Three studies (1,084 patients) were centrally selected and analyzed for the present meta-analysis. Combination of the three randomized controlled trials showed that there was no significant benefit of induction treatment plus surgery compared to combined chemoradiotherapy on 2-year OS [risk ratio (RR) =1.00; 95% CI, 0.85-1.17; P=0.98] and 4-year OS (RR =1.13; 95% CI, 0.85-1.51; P=0.39). However, from the subgroup analysis, it showed a significant PFS benefit (RR =1.78; 95% CI, 1.08-2.92; P=0.02) regarded chemoradiotherapy as preoperative induction treatment, compared with chemotherapy alone for induction treatment (PFS) (RR =1.05; 95% CI, 0.61-1.81; P=0.86).Conclusions
There was no significant OS benefit of induction treatment plus surgery compared with combined chemoradiotherapy in patients with NSCLC (stages IIIA-pN2) at 2 and 4 years. However, we could conclude PFS could be improved when radiation therapy was added into preoperative induction treatment. Given the potential advantages of adding radiation preoperatively, clinicians should consider using this treatment strategy in the stage IIIA-N2 disease after fully assessment of the patients. 相似文献11.

Background
Although first-generation epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) have shown efficacy in patients with advanced lung cancers, survival predictors with these drugs have not been extensively investigated. This study was performed to explore factors that may predict progression-free survival (PFS) in Chinese lung adenocarcinoma patients treated with EGFR-TKIs.Methods
We retrospectively collected clinicopathologic data on 208 patients who received either gefitinib, erlotinib or icotinib, including the patients’ EGFR mutation status and levels of six serum tumor markers [carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), cancer antigen 125 (CA125), squamous cell carcinoma antigen (SCC), cytokeratin-19 fragments (CYFRA21-1) and lactate dehydrogenase (LDH)]. Univariate and multivariate survival analyses were performed to identify independent prognostic factors associated with PFS.Results
At the study cutoff date, 189 (90.9%) of the patients met the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.0 criteria for progressive disease (PD), while 19 (9.1%) had stable disease (SD). The median PFS of the 208 patients was 12.4 months (95% CI, 11.0–13.8 months). In the multivariate analysis using a Cox proportional hazard model, a non-smoking history [hazard ratio (HR) =2.460; 95% CI, 1.484–4.079; P<0.001], first-line treatment (HR =1.500; 95% CI, 1.062–2.119; P=0.021), and a high pretreatment serum level of CEA (HR =1.424; 95% CI 1.026–1.977; P=0.035) were found to be significant predictors of a longer PFS.Conclusions
In Chinese lung adenocarcinoma patients treated with EGFR-TKIs, a non-smoking history, first-line EGFR-TKIs treatment and a high serum level of CEA were independent predictors of a longer PFS along with an EGFR-activating mutation. 相似文献12.
Background
Extrapleural pneumonectomy (EPP) has been used as a treatment option for selected patients with malignant pleural mesothelioma (MPM). The primary end-point of this study was disease-free survival (DFS). Prognostic indicators for local and overall DFS were statistically analyzed.Methods
Between October 1994 to April 2008, 59 patients who had complete macroscopic cytoreduction after EPP formed the basis of this report. In recent years, selected patients received adjuvant radiotherapy and pemetrexed combined with cisplatin or carboplatin. The clinicopathologic data of all patients were prospectively collected in a computerized database. Statistical analysis was performed by using Kaplan-Meier method and compared using the log-rank test. Cox-regression model was used for multivariate analysis.Results
The mean age at the time of EPP was 59 (S.D. = 8) years. Nineteen patients (32%) experienced perioperative complications. The median survival was 21 months (range 2 to 104). The local disease recurrence rate was 51%. The median local DFS was 22 months (0 to 73). The overall disease recurrence rate was 64%. The median overall DFS was 18 months (range 0 to 73). In multivariate analysis, epithelial subtype (p = 0.026) and adjuvant radiotherapy (p = 0.023) were independently associated with an improved local DFS. Adjuvant radiotherapy (p = 0.011) was also independently associated with an improved overall DFS.Conclusions
This study demonstrated that that local disease failure was still a considerable clinical problem following complete EPP. The data also showed that patients with epithelial histology and receiving adjuvant radiotherapy were associated with an improved disease control. 相似文献13.

Objectives
Postoperative recurrent primary spontaneous pneumothorax (PSP) is a troublesome complication and an important issue to be discussed. This study is to determine whether Re-video assisted thoracoscopic surgery (VATS) should be performed for postoperative recurrent PSP (PORP).Materials and methods
Patients who had underwent needlescopic VATS for PSP between Jan. 2007 and Dec. 2011 were reviewed.Results
VATS was initially performed on 239 patients with PSP in total. Eleven patients were found to have PORP during a follow-up period of 36.95 months. Nine patients received Re-VATS and only two patients receiving conservative treatment had no further recurrence. No conversion to thoracotomy, blood transfusion and prolong air leak were recorded.Conclusions
Even for smaller size cases, Re-VATS, which is technically feasible, safe and effective with better cosmetics and minor postoperative pain, should be a strong contender as priority treatment. 相似文献14.

BACKGROUND
Pegylated interferon (pegIFN) and ribavirin combination therapy remains the first-line treatment for chronic hepatitis C virus (HCV) infection. In contrast to the wealth of studies in treatment-naive patients, the effectiveness of retreatment in patients who have previously failed pegIFN-based therapy is largely unreported.AIM:
To assess the effectiveness of the retreatment of patients who have previously failed an initial course of pegIFN-based therapy with pegIFNα-2a and ribavirin.METHODS:
A post-hoc analysis of a multicentre open-label study was performed. Patients received pegIFNα-2a and ribavirin at a dose of 800 mg/day and later 1000 mg/day to 1200 mg/day for 24 to 48 weeks at the discretion of the investigator. Outcomes at week 12 (early virological response [EVR]) and week 24 (sustained virological response [SVR]) were analyzed.RESULTS:
Eighty-seven patients who had relapsed after previous pegIFN-based therapy (n=28; 78% genotype 1) or were nonresponders (n=59; 71% genotype 1) were analyzed. Of the relapsers, 86% achieved an EVR and 68% achieved an SVR. In relapsers to pegIFN monotherapy (n=15) or pegIFN plus ribavirin (n=13), 60% and 77% achieved an SVR, respectively. Fibrosis and genotype did not affect the likelihood of SVR in relapsers although this may be the result of the relatively small number of patients. In previous nonresponders, an EVR was achieved in 53% but an SVR occurred in only 17%. In nonresponders to pegIFN monotherapy (n=9) and pegIFN plus ribavirin (n=50), 33% and 14% achieved an SVR, respectively. Genotype did not affect SVR in nonresponders. Only 10% with a METAVIR score of F3 or F4 on liver biopsy achieved an SVR.CONCLUSIONS:
Relapse after previous pegIFN-based therapy is associated with a strong probability of treatment success whereas retreatment of those with previous nonresponse does not. 相似文献15.

Background/Aims
Erlotinib and gemcitabine combined chemotherapy is becoming the treatment of choice in advanced pancreatic cancer. We evaluated the effectiveness of treatment with erlotinib plus gemcitabine and the prognostic factors for chemotherapeutic response in Korean pancreatic cancer patients.Methods
Sixty-nine patients with advanced pancreatic cancer who were treated with daily erlotinib 100 mg orally and gemcitabine 1,000 mg/m2/30 min intravenous infusion on days 1, 8, and 15 of each 4-week cycle from 2006 to 2009 were included in this study. This study was a phase II single-center trial.Results
All 69 patients with advanced pancreatic cancer were chemotherapy-naïve. The objective response rate was 18.8%, and the overall tumor-stabilization rate was 49.2%. The median overall survival was 7.7 months (95% confidence interval [CI], 6.0 to 9.4 months). The median progression-free survival was 1.9 months (95% CI, 1.4 to 2.5 months). Prognostic factors for good chemotherapeutic response were good performance status and the presence of skin rash during chemotherapy. Patients with lower performance scores showed worse chemotherapeutic responses (odds ratio [OR], 7.6; 95% CI, 2.4 to 24.8). Poor responses were predicted by the absence of skin rash during chemotherapy (OR, 3.0; 95% CI, 1.4 to 6.3).Conclusions
Erlotinib and gemcitabine chemotherapy is a tolerable treatment regimen and has a favorable therapeutic effect in Korean patients with advanced pancreatic cancer. 相似文献16.

Background
Recurrent pyogenic cholangitis (RPC) is still a common disease in East Asia. The present study reviews the operative results for this disease in a single centre.Methods
The records of 85 patients who underwent surgical treatment for RPC from August 1995 to March 2008 were retrospectively reviewed.Results
Patients included 35 men and 50 women with a median age of 61 years. Types of surgery included: hepatectomy (65.9%); hepatectomy plus drainage (9.4%); drainage alone (14.1%), and percutaneous choledochoscopy (10.6%). There was no operative mortality. Complications occurred in 40% of patients and half the complications involved wound infections. The overall incidences of residual stone, stone recurrence and biliary sepsis recurrence were 21.2%, 16.5% and 21.2%, respectively, over a median follow-up of 45.4 months. The drainage-alone group and percutaneous choledochoscopy group had higher incidences of residual stone, stone recurrence and biliary sepsis recurrence. In hepatectomy patients, regardless of whether or not a drainage procedure had been performed, rates of residual stone, stone recurrence and biliary sepsis recurrence were 15.6%, 7.8% and 9.4%, respectively, over a median follow-up of 42.7 months.Conclusions
Hepatectomy is safe and yields the best treatment outcome for RPC. It should be considered as the treatment of choice for suitable patients with RPC. 相似文献17.

Background
This study aims to explore the feasibility and safety of video-assisted thoracic surgery (VATS) double sleeve lobectomy in patients with non-small lung cell cancer (NSCLC).Methods
Between June 2012 and August 2014, 13 NSCLC patients underwent thoracoscopic double sleeve lobectomy and mediastinal lymphadenectomy at three institutions. A retrospective analysis of clinical characteristics, operative data, postoperative events and follow-up was performed.Results
Thirteen NSCLC patients (median age, 60 years; range, 43-67 years) underwent thoracoscopic double sleeve lobectomy. There were no conversions to thoracotomy. Left upper lobectomy was most frequently performed (eleven patients). Median operative time was 263 minutes (range, 218-330 minutes), and median blood loss was 224 mL (range, 60-400 mL). The learning curve revealed reductions in both operative times and blood loss of ten cases from one center. Median data were duration of blocking pulmonary artery (PA) 72 minutes (range, 44-143 minutes), resected lymph nodes 24 (range, 10-46), stations of retrieved lymph nodes 6 (range, 5-9), thoracic drainage 1,042 mL (range, 500-1,700 mL), duration of thoracic drainage 5 days (range, 3-8 days), postoperative hospital stay 10 days (range, 7-20 days), and ICU stay 1 day (range, 1-2 days). One patient (1/13, 7.70%) suffered from pneumonia after surgery. There were no deaths at 30 days. Median duration of follow-up was 6 months (range, 1-26 months). And no local recurrences or distant metastasis were reported.Conclusions
Thoracoscopic double sleeve lobectomy is a technically challenging, but feasible procedure for NSCLC patients and it should be restricted to skilled VATS surgeons. 相似文献18.
Background
Patients successfully treated for Hodgkin''s lymphoma (HL) are at known risk for subsequent malignancies, the most common of which is lung cancer. To date, no population-based study has analyzed prognostic variables for overall survival (OS) among HL survivors who developed non-small cell lung cancer (NSCLC).Methods
For 187 HL patients who developed NSCLC (among 22,648 HL survivors), we examined the impact of the following variables on OS after NSCLC diagnosis: gender, race, sociodemographic status (based upon county of residence), calendar year and age at NSCLC diagnosis, NSCLC histology and grade, HL stage and subtype, radiation for HL and latency between HL and NSCLC. Patients were grouped by NSCLC stage as follows: localized, regional or distant. All patients were reported to the population-based Surveillance, Epidemiology, and End Results program. For those variables significant on univariate analyses, hazard ratios (HR) were derived from Cox proportional hazards model.Results
Sociodemogaphic status, gender and latency between NSCLC and HL did not significantly affect OS of any NSCLC stage group. For patients with localized NSCLC, a history of mixed celluarlity HL was associated with a 3-fold improved OS (P=0.006). For patients with regional NSCLC, prior radiotherapy for HL was associated with a 2-fold worse OS (P=0.025).Conclusions
A history of mixed cellularity HL subtype and a history of no radiotherapy for HL are favorable prognostic factors among patients who develop NSCLC. Further research into clinicopathologic and treatment-associated variables potentially affecting OS after second primary NSCLC among HL survivors is warranted. 相似文献19.

Introduction
Benign neoplastic, inflammatory or functional pathologies of the ampulla of Vater are mainly treated by primary endoscopic interventions. Consequently, transduodenal surgical ampullectomy (TSA) has been abandoned in many centres, although it represents an important tool not only after unsuccessful endoscopic treatment. The aim of the study was to analyse TSA for benign lesions of the ampulla of Vater.Patients and methods
All patients who underwent TSA between 2001 and 2014 were included. Patients were analysed in terms of indications, postoperative morbidity and mortality as well as long-term success.Results
Eighty-three patients underwent TSA. Indications included adenomas in 44 and inflammatory stenosis in 39 patients. 96% of the patients had undergone endoscopic therapeutic approaches prior to TSA (median no. of interventions n = 3). Postoperative morbidity occurred in 20 patients (24%). There was one procedure-associated death (mortality 1.2%). The mean follow-up was 54 months. Long-term overall success rate for TSA was 83.6%. After TSA for ampullary adenoma, the recurrence rate was 4.5%.Conclusion
TSA is an underestimated surgical procedure, which can be performed safely with high long-term efficacy. It can be implemented in clinical algorithms for patients with benign pathologies of the ampulla of Vater, particularly after unsuccessful endoscopic treatment. 相似文献20.
