ObjectiveTo explore the correlation between expression of thyroid transcription factor-1 (TTF-1) and gene mutation of epidermal growth factor receptor (EGFR) in patients with resectable lung adenocarcinoma (LAC). Method Sixty-seven LAC patients who underwent surgical resection in the Department of Cardiothoracic Surgery of Shanghai No.6 Hospital and Department of Thoracic Surgery, Renji Hospital, School of Medicine of Shanghai Jiaotong University from June 2009 to December 2012 were enrolled in this study. There were 40 male and 27 female patients with their age of 37-79 (56.7±1.8) years. TTF-1 expression was detected by immunohistochemistry. EGFR gene mutation was examined with mutant-enriched polymerase chain reaction. The correlation between TTF-1 expression and EGFR gene mutation was analyzed with corrected chi-square test. ResultsAmong the 67 LAC samples, 57 samples were TTF-1 positive and 10 samples were TTF-1 negative. There was EGFR gene mutation in 44 samples. EGFR gene mutation rate was 73.7% (42/57) in TTF-1 positive patients and 20.0% (2/10) in TTF-1 negative patients. The sensitivity of TTF-1 expression to predict EGFR mutation was 95.5%, and the specificity was 34.8%. ConclusionEGFR gene mutation rate is higher in LAC patients with positive TTF-1 expression. Positive TTF-1 expression can be used to predict EGFR gene mutation in LAC patients.
ObjectiveTo evaluate nutritional risk of patients with esophagus cancer before operation using nutritional risk screening 2002 (NRS2002), and explore the relationship between nutritional risk score and postoperative results. MethodsWe prospectively evaluated the nutritional risk of 225 patients with esophagus carcinoma patients who were admitted in Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine between March 2012 and March 2013 using NRS2002, in accordance with disease severity score, nutritional status score and age score(age≥70 years old score was 1 point, < 70 years old for 0 point). There were 136 males and 89 females with age of 64.0±8.2 years (ranged from 41 to 85 years). Postoperative results include postoperative complications, mortality, and length of hospital stay. ResultsThe number of patients with preoperative score≥3 points was 75 (33.3%), < 3 points was 150 (66.7%). The incidence rate of postoperative complications was 26.7% in the patients with NRS2002 score≥3 points, and was 12.0% in those with NRS2002 score < 3 points(P < 0.05). And the total hospital stay time was longer in the patients with NRS2002 score≥3 points than that with NRS2002 score < 3 points(29.80±7.94 d vs. 15.30±2.05 d, P < 0.05). Logistic regression analysis showed that the preoperative NRS2002, the underlying diseases, and surgical method were risk factors for postoperative complications. ConclusionsPreoperative NRS2002 score≥3 points can predict more postoperative complications and longer hospital stay time in patients with esophagus carcinoma. It indicates that scientific nutrition support is necessary for esophagus carcinoma patients with NRS2002 score≥3 points. NRS2002 can be used as a predictive index of nutritional risk after operation of esophagus carcinoma.
Objective To explore an effective and minimal invasive drainage procedure for intrathoracic anastomotic leakage after esophagectomy. Method A total of 14 patients (10 males and 4 females, aged 48 to 70 years) with encapsulated effusion due to thoracic anastomotic leakage after esophagectomy were performed accurate thoracic drainage which was guided by ultrasonography in Renji Hospital from January 2012 through December 2014. The J shape flexible catheter was placed into the effusion cavity near the leakage. Gasric drainage and enteral nutrition support were conducted as well. Result All the patients with leakage healed smoothly. The hospital stay was 27 to 94 days. Time of drainage was 17 to 89 days. The drainage volume was 5-260 ml per day. No complication related to drainage occurred. Conclusion Placing the J shape flexible catheter for plural drainage guided by ultrasonography or chest CT scan is a desirable and less injured therapy for intrathoracic leakage after esophagectomy.
