Postoperative radiotherapy (PORT), especially using modern technology, for patients with stage IIIA-N2 non-small cell lung cancer (NSCLC) is controversial. We retrospectively investigated 112 patients with stage IIIA-N2 NSCLC who underwent complete resection of the lung tumor in our institution from 1986 through 2003. Among the 91 patients determined suitable candidates for PORT postoperatively...

We present in this paper a wideband RF demodulator using a five-port correlator and a power detector for channel sounding applications. The demodulator has been fabricated using microstrip components. The correlator receives from the five-port qualities that allow it to be low-cost and less sensitive to the phase and amplitude imbalances. A calibration procedure is proposed to find the complex ...

BACKGROUND The aim of this study was to evaluate the feasibility of single-port video-assisted thoracic surgery (VATS) in the treatment of secondary spontaneous pneumothorax (SSP). METHODS Twenty-four patients who were scheduled to undergo single-port VATS for SSP were studied. The medical records of the patients were retrospectively reviewed. The mean follow-up duration was 26.1±19.8 months....

BACKGROUND To establish a prediction model in selecting fit patients with resected pIIIA-N2 non-small cell lung cancer (NSCLC) for postoperative radiotherapy (PORT), and evaluate the model in clinical practice. METHODS Between January 2003 and December 2005, 221 patients with resected pIIIA-N2 NSCLC were retrospectively analyzed. The effect of PORT on overall survival (OS) of patients with di...

BACKGROUND/PURPOSE The aim was to evaluate the prognostic significance of postoperative radiotherapy (PORT) and surgical type on local recurrence-free survival (LRFS) and overall survival (OS) in triple-negative breast cancer (TNBC) in the Egyptian population. PATIENTS AND METHODS We evaluated 111 patients with stage I-III TNBC diagnosed at our institute during the period from 2004 to 2009. P...

Taking the total volume of import and export trade of Ningbo port in 2004-2011 as the original data, a mathematical model of gray forecasting is established for the total volume of import and export trade of port. The paper predicts the total volume of import and export trade of Ningbo port in 2012-2015 during the 12th Five-Year Plan in accordance with the posterior variance testing. The analys...
