Objective To analyze the relationship between the epidermal growth factor receptor(EGFR) gene mutation and malignant pulmonary focal ground-glass lesion (fGGL). Methods We retrospectively collected the clinical data of 86 patients with surgical treatment in the department of cardiothoracic surgery of Changzheng Hospital from August 2012 to February 2015. There were 26 males and 60 females with a mean age of 56.14±10.55 years. We analyzed the relationship between the EGFR gene mutation and the related clinical data. Results Postoperative pathology showed atypical adenomatous hyperplasia (AAH) combined with focal adenocarcinoma in situ (AIS) or AIS in 10 patients, minimally invasive adenocarcinoma (MIA) in 15, and lepidic predominant adenocarcinoma (LPA) in 61. The EGFR gene mutation reports showed the exon 19 19-del mutation in 14 patients, exon 21 L858R mutation in 27, and exon 21 L861Q mutation in 2. There was no difference between the mutation of EGFR gene and clinical factors except age and smoking (P>0.05). Till June 30, 2015, all patients were alive and follow-up was 440.48±186.61 days. Conclusion The EGFR gene in patients with malignant pulmonary fGGL shows a higher mutation rate, which provides important clinical reference data for the basic research and the clinical treatment.
ObjectiveTo analyze the surgical techniques and perioperative patient management of bronchial sleeve resection and plasty, carinal resection and reconstruction, and angioplasty in the treatment of locally advanced central type of lung cancer and summarize the experiences. MethodsWe retrospectively analyzed the clinical data of 21 locally advanced central type of lung cancer patients with bronchial sleeve resection and plasty, carinal resection and reconstruction, and angioplast in our hospital from December 2011 through November 2014. There were 17 males and 3 females with a mean age of 63.2±6.2 years. All operations were successful. The time of operation was 3.29±0.75 h. The hospitalization time was 25.48±22.31 days. No death ocurred during perioperative period. Postoperative complications were found in 3 patients, including 2 patients with atelectasis and 1 patient with bronchopleural fistula. ConclusionBronchial sleeve resection and plasty, carinal resection and reconstruction, and angioplasty apply to treat locally advanced central type of lung cancer not only maximally remove the lung cancer tissue, but also maximally reserve the healthy lung tissue.
Objective To detect the expression of forkhead box P3 （FOXP3 ）gene in esophageal squamous cell carcinoma(ESCC) and provide a new basis for immunotherapy of esophageal cancer. Methods Based on fluorescent TaqMan methodology, a realtime quantitative reverse transcription polymerase chain reaction (RT-PCR) for detecting the expression of FOXP3 was set up. In this method, a cloning vector pMD 18-T-FOXP3 was constructed as a standard plasmid. The specific expression of FOXP3 in 42 patients with ESCC and 30 healthy controls were measured by using GeneAmp 7500 Sequence Detection Systems. Results FOXP3 mRNA copy number in ESCC was significantly higher than that in healthy control tissue ［(72.20±23.10)×104copy/μg RNA vs.(0.68±0.34)×104 copy/μg RNA；Plt;0.05］. Conclusion A realtime quantitative RT-PCR method for detecting the expression of FOXP3 gene in ESCC has been successfully established. The expression level of FOXP3 is increased in ESCC compare with healthy controls.
ObjectiveTo evaluate effect and safety of a novel conservative therapy for post-lobectomy bronchopleural fistula. MethodsWe retrospectively analyzed the clinical data of 20 patients with post-lobectomy bronchopleural fistula in our hospital between 2000 and 2013 year. There were 12 males and 8 females at average age of 67.7±8.7 years. Endobronchial naso-bronchial lavage (ENBL) was used for 10 patients (an ENBL group). Traditional method-thoracostomy drainage tube (TDT) was used for the other 10 patients (a TDT group). ResultsCompared with the TDT group, shorter hospital day was found in the ENBL group (49.7±9.6 d versus 68.3±9.8 d, P < 0.001). Fistula healing time was also shorter in the ENBL group than that in the TDT group (43.7±9.7 d versus 62.6±8.8 d, P < 0.001). There were lower complication rate, less inflammatory reaction, and better recovery in the ENBL group than those in the TDT group. ConclusionENBL may be a promising procedure for post-lobectomy bronchopleural fistula.
Splanchnicectomy is a minimally invasive and effective method of treating chronic upper abdominal pain in cancer. It offers good, short-term pain relief, reduces morphine consumption, and improves patients' satisfaction. In the wake of developments in minimally invasive technology, the method has brought a number of new breakthroughs. We reviewed the effect of the success of splanchnicectomy.
ObjectiveTo evaluate the efficiency and clinical outcomes of endoscopic thoracic sympathectomy (ETS) with flexible thoracoscopy under local anesthesia with monitored anesthesia care in primary palmar hyperhidrosis. MethodsFrom March 2011 to March 2013, we performed ETS with flexible thoracoscopy under local anesthesia with monitored anesthesia in 23 patients with primary palmar hyperhidrosis (PH), including 10 males and 13 females with their age of 25.6±7.2 years (range, 17-32 years). T3 sympathectomy was performed with flexible endoscopy under local anesthesia with monitored anesthesia care. All patients were followed up until May 2014. ResultsDuring surgery, the vital signs of the patients remained stable. Operation time was 30-40 minites. The symptom of PH disappeared right in the surgery. All patients were discharged from the hospital on the 2nd postoperative day. One patient received unilateral sympathectomy because of pleural adhesion. Other 22 patients received follow-up to May 2014 and no reoccurrence was reported. ConclusionETS with flexible thoracoscopy under local anesthesia with monitored anesthesia is a safe, microinvasive and effective method.
