Metastasectomy With Standardized Lymph Node Dissection for Metastatic Renal Cell Carcinoma: An 11-Year Single-Center Experience
2013
Background Pulmonary metastasectomy (PM) for metastatic renal cell carcinoma is an established method of treatment for selected patients. The incidence of intrathoracic lymph node metastases (ITLNM) and outcomes remain controversial. The purpose of this study was to determine the incidence of ITLNM and long-term outcome of PM for metastatic kidney cancer. Methods From January 1999 to December 2009, 116 patients (82 men, age 61.7 ± 9.0 years) with metastases from kidney cancer underwent PM and systematic lymph node dissection with curative intent. Kaplan-Meier analyses, log-rank test, and Cox regression analyses were used to estimate survival and to determine prognosticators of survival. Res…
pT2 Adenocarcinoma of the Esophagus: Early or Advanced Cancer?
2013
Background There is an increasing trend to include patients with esophageal carcinoma invading the muscularis propria (pT2) in neoadjuvant therapy regimens. But it is unclear which patients have prognostic benefit from this strategy. The aim of this study was to assess the prognosis and prognostic factors in patients with pT2 esophageal adenocarcinoma to further optimize treatment strategies. Methods Included were patients with pT2 esophageal adenocarcinoma treated operatively at three centers specializing in upper gastrointestinal surgery. There were 159 patients (139 male) without induction therapy; median age was 64.5 years. Survival was analyzed by univariate and multivariate analysis. …
Incidence of venous thromboembolism in patients undergoing thoracotomy for lung cancer
2008
Limited information exists on the incidence of symptomatic venous thromboembolism (vTE) in patients undergoing chest surgery for lung cancer. Several factors increase the thromboembolic risk in patients undergoing surgery for lung cancer: the intrinsic procoagulant effect of cancer,extensive surgical intervention, dependent limb position in the operating room, and vessel injury consequent to the operation. Furthermore,these patients might be especially vulnerable to pulmonary embolism (PE) because of the loss of lung tissue and the presence of chronic obstructive pulmonary disease and cardiovascular diseases caused by smoking.t Older studies found a very high incidence of thromboembolic eve…
Detection of lung cancer in exhaled breath with an electronic nose using support vector machine analysis
2017
Lung cancer is one of the most common malignancies and has a low 5-year survival rate. There are no cheap, simple and widely available screening methods for the early diagnostics of lung cancer. The aim of this study was to determine whether analysis of exhaled breath with an artificial olfactory sensor using support vector analysis can differentiate patients with lung cancer from healthy individuals and patients with other lung diseases, regardless of the stage of lung cancer and the most common comorbidities. Patients with histologically or cytologically verified lung cancer, healthy volunteers and patients with other lung diseases (e.g. chronic obstructive pulmonary disease (COPD), asthm…
Functional assessment of the quality of human hepatocyte preparations for cell transplantation.
2008
Hepatocyte transplantation is an alternative therapy to orthotopic liver transplantation for the treatment of liver diseases. Good quality freshly isolated or cryopreserved human hepatocytes are needed for clinical transplantation. However, isolation, cryopreservation, and thawing processes can seriously impair hepatocyte viability and functionality. The aim of the present study was to develop a fast and sensitive procedure to estimate the quality of hepatocyte preparations prior to clinical cell infusion. To this end, cell viability, attachment efficiency, and metabolic competence (urea synthesis and drug-metabolizing P450 activities) were selected as objective criteria. Viability of hepat…
Retrospective dosimetry for Latvian workers at Chernobyl.
2001
Between 1986 and 1991 approximately 6500 Latvian inhabitants were recruited for clean-up work at the Chernobyl nuclear power plant. Their absorbed doses are usually unknown, because less than half of them had their external exposure officially documented. Clinical investigations show a high morbidity rate for these clean-up workers when compared with that of the general population. In order to understand the causes of their diseases and the impact of ionising radiation, electron spin resonance (ESR) has been used to measure the absorbed doses in human tooth enamel. The doses estimated by ESR were between two and three times higher than previously documented and are in accord with the result…
TC perfusionale nell'ischemia cerebrale acuta: Valore predittivo dei parametri di perfusione cerebrale nel discriminare il tessuto vitale da quello i…
2007
Purpose. The aim of this study was to assess the value of computed tomography (CT) perfusion parameters in differentiating tissue viability in acute stoke patients. Materials and methods. Thirteen patients (mean age 63.3 years) with nonhaemorrhagic stroke underwent multidetector perfusion CT within 3 h of symptom onset. Images were continuously acquired at the basal ganglia over 40 s during injection of 90 ml of iodinated contrast medium injected at a rate of 9 ml/s with a 9-s delay. Z-axis coverage was 20 mm. All patients underwent diffusion-weighted magnetic resonance imaging (DWI) within 12 h of perfusion CT to define the extent of the infarct. Perfusion CT data were analysed in regions …
The influence of histopathologic criteria on the long-term prognosis of locally excised pT1 rectal carcinomas: results of local excision (transanal e…
2006
Local excision of early rectal cancer is a controversial issue, which is in part because of differences in the evaluation of histopathologic criteria. This prospective study was designed to determine prognostic factors for recurrences and the need for reoperation.In 105 of 118 patients with pT1 carcinomas and local excision, results of recurrence rates and ten-year cancer-free survival were studied separately according to different histologic criteria (R0, R1, Rx, Ror = 1 mm, high-/low-risk situation), tumor localization (anterior, posterior, lateral wall and third of rectum), size, and degree of resection (full-thickness/partial wall). Patients were grouped into local excision (n = 89) and…
Low rectal cancer: abdominoperineal resection or low Hartmann resection? A postoperative outcome analysis.
2011
BACKGROUND In distal rectum cancers, when the sphincters are not affected and it is not possible to perform a coloanal anastomosis because of the presence of comorbidities or the advanced age of the patient, a low Hartmann resection with total mesorectal excision can be performed. Low Hartmann resection is usually considered to be a shorter procedure and to have an inferior morbidity compared with abdominoperineal resection of the rectum. OBJECTIVE This study aimed to compare the postoperative outcome of a series of patients with low rectal cancer who have undergone either low Hartmann resection or abdominoperineal resection. DESIGN This study is a retrospective analysis of data collected i…
Incidence of liver retransplantation and its effect on patient survival.
2008
Purpose. The purpose of this study was to review our institutional experience with re-liver transplantation (OLT) after split and full-size OLT. Patients and methods. We evaluated data corresponding to retransplanted patients over an 8-year period who underwent deceased donor OLT at our institution. Variables analyzed included indications for primary OLT, and re-OLT, the type of graft used during the initial versus re-OLT, the time from initial to re-OLT, and patient survival after re-OLT. Results. Sixty-four of 697 first OLT (9.2%) required re-OLT. Forty-nine cases were among 637 (7.6%) full-size OLT, while 15 were among 60 (25%) split OLT (P <.001). Median time to re-OLT was 8 days (range…
