Analysis on CT in diagnosis of lymph node metastasis of thoracic esophageal cancer with minimum diameter greater than 1 cm / 中华外科杂志

Objectives@#To evaluate the diagnostic value of CT for lymph node metastasis of thoracic esophageal carcinoma with a diameter of more than 1 cm, and to find the optimal diagnostic index by comparing relevant CT indexes.@*Methods@#Totally 80 patients with pathologically proved thoracic esophageal cancer with preoperative CT examination revealed lymph node diameter greater than 1 cm admitted at Department of Thoracic Surgery, the First Affiliated Hospital of University of Science and Technology of China from January 2016 to January 2018 were enrolled in this study. There were 70 males and 10 females, aging of (60±14) years (range: 40-85 years). According to the pathological result of lymph nodes, all the patients and lymph nodes were divided into two groups (N+group: 47 patients, 62 lymph nodes; N-group: 33 patients, 39 lymph nodes). The average number of dissected lymph nodes were 21±4 and 101 lymph nodes′ diameter were greater than 1 cm. The clinicopathologic factors, postoperative complications, lymph node dissection and relevant CT indexes like the minimum diameter of lymph nodes (Min D), the maximum diameter of lymph node (Max D), lymph node axial ratio(LAR), the enhancement of lymph node (ELN) and the boundary of lymph node (BLN) were compared. The clinicopathological data, lymph node dessection and CT parameters of the two groups were compared by t test, χ2 test or Wilcoxon rank sum test. Receiver operating characteristic (ROC) curve analysis was used to compare the ability to predict lymph node metastasis between Min D, Max D, LAR, ELN and BLN. Multiple Logistic regression analysis were performed to determine the independent variables for prediction of lymph node metastasis.@*Results@#The difference of tumor segmentation, pN stage, pTNM stage, total number of metastatic lymph nodes, total number of abdominal lymph node metastases, Min D, Max D, ELN and BLN between the two groups were statistically significant. The results of univariate and multivariate analyses showed that gender (OR=0.128, 95%CI: 0.019 to 0.858, P=0.034), pTNM stage (OR=1.514, 95%CI: 1.020 to 2.247, P=0.039), Min D (OR=0.102, 95%CI: 0.010 to 0.995, P=0.050) and LAR (OR=0.195, 95%CI: 0.052 to 0.731, P=0.015) were the independent relative factors. The area under the curve of ROC curve analysis of Min D, Max D, LAR, ELN and BLN were 0.679, 0.666, 0.561, 0.650 and 0.820, respectively. BLN was the best CT index to diagnosis lymph node metastasis, while the accuracy of dignosis of lymph node metastasis of BLN was 97.0%. The Youden index of Min D, Max D and LAR were 1.25 cm, 1.64 cm and 0.77, respectively. Combining the BLN and ELN had a higher diagnostic rate (97.0%) of lymph node metastasis.@*Conclusions@#CT has high diagnostic value for lymph node metastasis in thoracic esophagel cancer when the lymph node diameter is greater than 1 cm. BLN is the best diagnostic index for lymph node metastasis.

Application of new ERCC1 antibody for molecular diagnosis of platinum chemotherapy in non-small cell lung cancer / 中国癌症杂志

Background and purpose:High expression of excision repair cross-complementing 1 (ERCC1) is related to resistance in patients treated with platinum-containing regimens. The ERCC1 antibody 8F1 was usually used in past studies, but it was found to have no-speciifcity recently. This study aimed to investigate the predictive role of a new ERCC1 antibody 4F9 to platinum chemotherapy in non-small cell lung cancer (NSCLC) patients. Methods:Expression of ERCC1 was detected using antibody 4F9 by immunohistochemistry (IHC) in 72 NSCLC tissues. The relationship between the expression of ERCCl and the clinical pathological parameters, the efficacy of platinum chemotherapy and overall survival of patients were explored by statistical analysis. Results: The high expression of ERCCl protein was 55.5%in 72 cases. There was no signiifcant correlation between the ERCC1 expression with gender, age, pathological type, clinical stage and lymphatic metastasis (P>0.05). Patients with low expression of ERCC1 had signiifcantly higher response rates to platinum chemotherapy, longer median survival time and 2-years survival rate comparing with those with high expression of ERCC1 (62.5%vs 37.5%;22.9 vs 18.4 month;46.9%vs 37.5%), respectively (P<0.05). Conclusion:The expression analysis of ERCC1 using new ERCC1 antibody 4F9 by IHC method is helpful to assign chemotherapeutic regimen, and guide individual platinum chemotherapy for post-operation patients.

Objective:To investigate the feasibility, safety, and short-term effect of minimally invasive McKeown esophagecto-my. Methods: We conducted a retrospective evaluation of 88 patients with esophageal carcinoma who received minimally invasive esophagectomy in our center from October 2013 to April 2014. Among the 88 patients, 46 patients underwent total endoscopy McKe-own esophagectomy (TEME) and 42 patients underwent thoracoscope combined with laparotomy Mckeown esophagectomy (TLME). The clinicopathologic factors, operational factors, and postoperative complications of the two approaches were compared. Results:The two groups were similar in terms of age, sex, American Society of Anesthesiologists grade, tumor location, preoperative staging, and co-morbidity. The TEME approach was associated with a significant decrease in abdominal blood loss and postoperative pain relative to the TEME approach (P0.05). The total morbidity and total re-spiratory complications in the TEME group were lower than those in the TLME group (P<0.05). Incidences of pneumonia, arrhythmia, wound infection of minor complications, and pneumonia of major complications were relatively low in the TEME approach. Conclu-sion:Our TEME technique can be safely and effectively performed for cervical anastomosis during esophageal surgeries to achieve fa-vorable early outcomes.

The proportion of circulating Tfr and Tfh cells were determined by flow cytometry; real-time PCR was performed to detect the expression of transcription factors and regulatory factors of Bcl-6, c-Maf, Blimp-1 and PD-1 mRNA; ELISA was used to detect plasma concentration of IL-2, IL-6, IL-10 and IL-21.</p><p><b>RESULTS</b>(1)The proportion of Tfh cells were significantly higher (P<0.05), while the Tfr cells and the ratio of tfr/Tfh cells in ITP patients were significantly lower than that in health controls (P<0.05); (2)Correlation analysis showed that the Tfr cells and the ratio of Tfr/Tfh were positively correlated with the platelet counts and negatively with the levels of PA-IgG, while the proportion of Tfh cells was positively correlated with the levels of PA-IgG and negatively with the platelet counts in peripheral blood; (3)Transcription levels of Bcl-6 and c-Maf mRNA in CD4(+) T lymphocytes cells were significantly elevated, the Blimp-1 mRNA in CD4(+) cells and PD-1 mRNA levels of Treg were lower in ITP patients in comparison with healthy controls; (4)The higher Plasma concentration of IL-21, and lower concentration of IL-2 were found in ITP patients.</p><p><b>CONCLUSION</b>(1)The lower proportion of Tfr cells and higher proportion of Tfh cells, as well as the abnormal ratio of Tfr/Tfh might account for the decreased platelet counts to be further involved in the immunological pathogenesis of children ITP; (2)The changes of plasma cytokines IL-2, IL-21 in microenvironment and the over-expression of Bcl-6 mRNA, c-Maf mRNA and the lower-expression of Blimp-1 mRNA in CD4(+) T cells, and over-expression of PD-1 mRNA in Treg cells might be account for the abnormal ratios of Tfr/Tfh cells in ITP patients.</p>

A retrospective study of short-term outcomes of minimally invasive Ivor-Lewis esophagectomy and McKeown esophagectomy for thoracic middle-lower esophageal carcinoma / 中华胸心血管外科杂志

Objective To investigate the feasibility,safety and curative effect of combined laparoscopic and thoracoscopic esophagectomy for esophageal carcinoma and gastro-esophageal anastomosis in right thoracic cavity.Methods We retrospectively evaluated 357patients with esophageal carcinoma who received minimally invasive esophagectomy(MIE) in our center between October 2011 and March 2014.Of those 357 patients,219 underwent MIILE and 138 underwent MIME.The clinicopathologic factors,operational factors,postoperative complications and postoperative recurrence were compared.Results The 2 groups were similar in terms of age,sex,American Society of Anesthesiologists grade,tumor location,preoperative staging.The MILLE approach was associated with no significant decrease in surgical blood loss.Duration of operation,chest tube duration,hospitalization expenses and postoperative stay relative to the MIME approach(P ＞ 0.05).There was no significant difference between the 2 groups in postoperative complications(P ＞0.05).The MIILE approach was associated with significantly fewer anastomotic fistula,RLN injury,anastomotic stensis than the MIME approach(P ＜0.05).Conclusion Our MIILEtechnique can be safely and effectively performed for intrathoracic anastomosis during esophageal surgeries with favorable early outcomes.

Video-assisted thoracoscopic surgery and conventional radical operation on stage Ⅰ , Ⅱ esophageal cancer / 中国医师进修杂志

Objective To compare the results and safety between video-assisted thoracoscopic surgery ( VATS ) and conventional radical operation in patients with stage Ⅰ , Ⅱ esophageal cancer. Methods Retrospectively reviewed 43 patients with stage Ⅰ , Ⅱ esophageal cancer,underwent either VATS radical operation (VATS group,16 cases) or conventional radical operation (control group,27 cases ) from September 2007 to September 2009. Patient's operative characteristics and postoperative courses were compared between two groups. Results In VATS group the operation time was ( 115.6 ± 48.0) min,the peri-operative blood loss was ( 131 ± 71 ) ml,the first postoperative day chest lead quantity was (331 ± 170)ml, the time of postoperative chest tube was (7.25 ± 2.35) d,the postoperative 36 h visual analogue scale (VAS) was (3.4 ± 1.2) scores,the postoperative drainage of chest was ( 1281 ± 534) ml,the 72 h postoperative locomotor activity of right upper extremity was (5.1 ± 1.5) cm. While in control group was ( 145.6 ± 20.6)min, (292 ± 111 ) ml, (494 ± 194) ml, ( 10.00 ± 2.79 )d, (7.3 ± 1.4) scores, ( 1780 ± 731 ) ml, ( 15.6 ± 3.1 )cm respectively (P ＜ 0.01 or ＜ 0.05 ). The lymph node dissection number,the total cost of hospital between were no statistically significant differences in two groups (P ＞0.05). Conclusion Comparing with conventional radical operation, VATS radical operation for patients with stage Ⅰ , Ⅱ esophageal cancer appears to be as effective but less morbid.
