ABSTRACT

Objective To explore the clinical significance regarding monitoring circulating tumor cells in early stage lung adenocarcinoma.Methods From November 2015 to January 2018,48 patients with stage Ⅰ lung adenocarcinoma were included in the study.BCAR1 expression in CTCs in peripheral blood were detected by using CanPatrolTM and RNA in situ hybridization detection.Results Among the 48 cases,CTCs and BCAR1 (+)-CTCs were detected in 41 cases(85.4%) and 30 cases(62.5%),respectively.Number of BCAR1 (+)-CTCs seemed to be significantly positively related to that of CTCs.BCAR1 (+)-CTCs were more likely to appear in the M-CTCS and E&M-CTCS.BCAR1 (+)-CTCs remarkably increased in three relapsed cases.Furthermore,there were 19 stable cases who had postoperative CTCs data:(1) in 12 patients,either CTCs or BCAR1 (+)-CTCs were significantly reduced or remained stable;(2) in 7 cases,CTCs increased,but BCAR1 (+)-CTCs remained stable in 2 cases,reduced in 1 case,and the other 4 cases underwent close follow-up.Conclusion Evaluation of BCAR1 (+)-CTCs possibly can be contributive to prediction of early lung adenocarcinoma recurrence or metastasis.

ABSTRACT

Objective Summing up and analyzing outcome and influencing factors following thymectomy in patients with ocular myasthenia gravis tries to provide clinical evidence for an option of the treatment modalities.Methods From May 2007 to November 2014,thymectomy was performed in 129 patients with ocular myasthenia gravis consisting of 110 patients by Video-assisted thoracoscopic surgery(VATS) and 19 by partial sternotomy.Follow-up information was obtained by outpatient visit and telephone contact.The outcome evaluation after thymectomy was classified into full remission,partial remission,unchanged and deteriorated.Statistical analysis was done using x2 test and Cox regression model.Results There was no perioperative death.Seven(5.4%) postoperative complications occurred and cured after treatment.Follow-up was complete in 123 patients(95.3%) and the mean duration of follow-up was 49(range 21-99) months.Surgical outcome revealed full remission in 40 patients,partial remission in 68,unchanged in 9 and deteriorated in 6 patients.Response(full remission and partial remission) rate was 87.8% and no benefit(unchanged and deteriorated) rate was 12.2%.Four of 6 patients in deteriorated condition progressed into generalized myasthenia gravis(3.3%).The significant difference was noted in 24 months or less of preoperative clinical duration (P =0.004) and thymic hyperplasia (P =0.001) in postoperative pathology among the full remission,partial remission and no benefit group.On the other hand,there was no statistical difference in sex,age,symptoms,comorbidities,preoperative taking acetylcholinase inhibitor,corticosteroid,surgical approach,and associated thymona among the three groups.Multivariate Cox regression analysis also demonstrated that a preoperative duration of symptoms 24 months or less and postoperative histology being thymic hyperplasia favourably influenced the outcome.Conclusion The role of thymectomy in patients with ocular myasthenia gravis can relieve symptoms effectively and avert or decrease the potential development of generalized symptoms.Thymectomy,which has a low postoperative mortality and morbidity,may be a first-line option of the therapeutic armamentarium to treat ocular myasthenia gravis.Thymectomy via VATS has clinical advantages of minimal trauma,less pain,fast recovery,and the comparable clinical results over via the traditional sternotomy.Therefore,this procedure deserves to be advocated for ocular myasthenia gravis.

ABSTRACT

Objective To assess the therapeutic efficacy of a recombined adenovirus expressing p53 (rAd-p53) via intrapleural injec-tion in the treatment of lung cancer with malignant pleural effusion. Methods Thirty-six cases with lung cancer and malignant pleural effu-sion were randomly divided into two groups,which were given intravenous injection of Nedaplatin with (observation group,n=20) or without (control group,n=16) intrapleural injection of rAd-p53,respectively. Between the two groups,the efficacy in treatment of pleural effusion, the amelioration of maximal ventilatory volume ( MVV) ,Kamofsky scoring ( KPS) and quality of life were compared. Results The efficacy in treatment of pleural effusion in observation group are significantly higher than that in control group(17/20 vs. 50%,P<0. 05). The cases with KPS≥80 in observation group were significantly increased following treatment (5/20 vs. 11/20,P <0. 05). However,there was no difference with the cases in control group. Conclusion Intrapleural injection of recombinant adenovirus expressing p53 (rAd-p53) is effec-tive to reduce the occurrence of malignant pleural effusion and increase the quality of life remarkably.

ABSTRACT

Objective To analyze the perioperative clinical characteristics of non-small cell lung cancer ( NSCLC ) complicated with dermatomyositis ( DM) . Methods Six cases of NSCLC complicated with DM received lobectomy and lymph node dissection by video-assisted thoracoscopic surgery. The same kind of operations were carried out in another six NSCLC cases without DM in the same period. The twelve cases in two groups were 1 ∶ 1 matched study. The operation time, operative blood loss, postoperative pneumonia or atelectasis rate, postop-erative wound recovery, thoracic drainage in postoperative three days, incidence of postoperative atrial fibrillation, perioperative hospital stay were compared between the two groups. Results In operative time, blood loss and thoracic drainage volume in postoperative three days, there was no significant difference in two groups (P>0. 05). In paients with and without DM, the occurrence rate of atrial fibrillation was respectively 50. 00% (3/6) and 16. 66% (1/6), the occurrence rate of postoperative pneumonia or atelectasis was respectively 50. 00%(3/6) and 16. 66% (1/6), and postoperative hospital stay was respectively (16. 28 ± 3. 61) d and (11. 11 ± 2. 92) d. It was of significant differences (P<0. 05). Conclusion Compared with NSCLC patients without DM, postoperative atrial fibrillation and pneumonia or atelec-tasis occured more often in the DM cases. And patients with DM have longer hospital stays.

ABSTRACT

Stomach and colon are always used to reconstruct esophagus after esophagectomy. However, alternative procedures to reconstruct or repair esophagus are required if the patients suffered from gastric or colonic diseases, underwent gastric colonic operations or had severe local esophageal stricture. More than ten kinds of skin flaps and myocutaneous flaps, which are classified into free or pedicled ones, are used to reconstruct or repair esophagus. Microvascular anastomosis is required while using free flaps. Necrosis of the free flaps is prone to developing once the vascular occlusion occurs. The pectoralis major myocutaneous and latissimus dorsi pedicled flaps have sufficient blood supplies. However, both are bulky and difficult to reconstruct a circumferential esophagus through contouring a tube. Platysma myocutaneous flaps have a large surface area and are supplied from multiple vessels. Single lateral and bilateral platysma myocutaenous flap can be applied to repair the cervical esophageal defect and circumferential cervical esophagus, respectively. The use of platysma myocutaneous to repair and reconstruct cervical esophagus is a procedure easy to perform and confer excellent outcomes. There is no development of ulcer and hair growth after long-term follow-up and resistance to radiotherapy.

ABSTRACT

Objective To evaluate the short-term outcome of side-to-side staple cervical esophagogastrostomy after esophagectomy. Methods The clinical data of 105 patients with esophageal cancer who were admitted to the Daping Hospital from January 2006 to March 2009 were retrospectively analyzed. Of the 105 patients, 97 received side-to-side stapled cervical esophagogastrostomy and eight received traditional hand-sewn end-to-end cervical esophagogastrostomy. Nine patients were selected from the 97 patients who received side-to-side stapled cervical esophagogastrostomy to conduct matched pair analysis. The efficacy of the two methods was analyzed using the t test. Results No postoperative death was observed. The mean operation time of side-to-side staple cervical esophagogastrostomy was (21 ± 3 )minutes (range, 15-30 minutes). Postoperative complications were observed in 16 patients, including pulmonary complications in seven patients, vocal cord paralysis in four patients, anastomotic leakage in three patients and anastomotic stricture in two patients. The mean anastomotic diameter of patients who received side-to-side staple cervical esophagogastrostomy was ( 3. 01 ± 0. 17 ) cm, which was significantly longer than ( 1.69 ± 0. 26) cm of patients who received traditional hand-sewn end-to-end cervical esophagogastrostomy (t =2. 093, P <0.05 ). Dysphagia occurred in two patients who received side-to-side stapled cervical esophagogastrostomy and in four patients who received traditional hand-sewn end-to-end cervical esophagogastrostomy.Conclusions Side-to-side stapled cervical esophagogastrostomy is simple, safe and effective for patients with esophageal cancer after esophagectomy. This technique could decrease the incidence of postoperative dysphagia and improve the pharyngo-esophageal motor function.
